:Genetics

Although identical the genetic composition of the neurons associates I smell with it in the fruit fly, the scientists are a stage more close to understanding as definitive neurons perceive specific cheiros, in accordance with a set free article May in 27, 2008 in the genetics of PLoS of the periodical of the open access.

The embryonic development starts with an only stack, contends the genetic information to create all the parts of the organism that if is becoming. While this stack if divides, it supplies this full compliment of the genes to each stack of subsequent son, who has in turn the potential if to transform some of the found stacks into the organism in a known property as totipotency. Much still has to be learned on as and in because these stacks if differentiate, a great scale and a small scale, and to understand these regulating processes is the genetic foundation of developing biology.

In the fruit fly, of gnero drosophila, two agencies are related to the direction of smell: the main antennas that extend of palps and maxillary in the mouth. In palps, it has six different types of current neurons to transmit the information of the sensorial area to the proper brain. Based in these tests standards, receptors different will discriminate odors different. Each type has a test specific and predizvel standard of receptors olfactory, but until it was not opened here as the neurons had been instructed to become in these different but highly predizveis ways.

To investigate this question, the ray of Anandasankar and the colleagues in the University of Yale had compared the genetic sequences recently published of all the 12 species typically studied of drosophila. In making this, they had identified regions of the upstream ADN and close to the genes for receptors they themselves that are almost identical through the species. To assume that these were the control regions, that will influence when and as the genes will become, the team modified genetically definitive regions of experimental control, showing that these genes were certainly necessary for the control of this part of the development. Some regions regulate the expression of the receiver positively, in way that if are not current, the necessary proteins do not appear. Another one regulates it negative, as soon as when they are lacking receptors will appear, same in the wrong neurons.

Notvel, these regulating sequences can have other papers in the nervous system — they can equally potential actuar in the process to connect the neurons to other neurons in the antennas, called orientation the axnio. This suggests that these genes are not only necessary for the direction of smell, but can equally be integral to the nervous system of the drosophila.

The Anti-HIV drugs reduce the cause of some forms of the loss of the vision

A therapeutical use new potential for the drugs anti-HIV known as inhibiting of protease was suggested by a team of the investigators of the College of Medicine, the Boston, and the Inserm U848 of Harvard, France, in consequence of its work in a model of the rat of the retinal detachment.

An important cause of the loss of the vision in many illnesses of the eye is the death (for a known process as the apoptosis) of stacks of nerve in the eye (known as photoreceptors) after the retinal detachment. In the study, the inhibitor administration of protease of the HIV of alive voice diminished marked the apoptosis of the photoreceptor in the model of the rat of the retinal detachment. The Mechanistic analysis in cultures of retinal stack of the rat and in the rats that to express diminished amounts of specific proteins established that the inhibitors of protease of the HIV had interrupted two ways moleculars that they cause the stack death apoptotic, ambo affect the known compartments of stack as the mitocndria. Because the same ways deinduo of the stack apoptotic had been shown to be activated in the human retinas after the retinal detachment, the authors suggest that even so the inhibitors of protease of the HIV cannot reattach the retina, can be of the clinical benefit with its ability to hinder the apoptosis it photoreceptor that after has a basic paper in the loss of the vision the retinal detachment.

What identifies to the cancerous cells that cause relapse and metstase? Not CD133

The data new, generated by Shahin Rafii and colleagues, in the medical college of Weill of the University of Cornell, New York, with the analysis of stacks and human rats of the cancer of clon, had shed the doubt in the assignment recently to consider of protein CD133 as a marker of stacks of connecting rod of the cancer of clon - a term given to the small number of stacks inside of a cancer of clon that they can probably cause a new tumor and that they are consequently responsible for the return and metstase of the tumor.

In the study, the rats had been projected such that had expressed a protein of the reporter in all part that CD133 is expressed normally. In contrast with the preceding studies where expression CD133 had been shown to be expressed very by few stacks in colon, this protein of the reporter was detected in many stacks in colon, including stacks of the not-connecting rod. A similarly wide expression of CD133 in colon of both the rats and human beings were observed to use the antibodies that bind CD133. The analysis of preliminary tumors of colon of the human and spontaneous rat it indicated that CD133 estve expressed by the majority of stacks. Inversely, all the stacks human beings of the cancer of clon that they had multiplied for metstese to the liver had not expressed CD133. More, the stacks of CD133+ and CD133- had generated transplantadas tumors when in rats immunocompromised. Some of the reasons for which this preceding study and inquiries such distinct conclusions if or not of CD133 alcangaram is a marker of the cancer of clon the stacks of connecting rod that are written down by the argued authors and in detail in a commentary of accompaniment for Mark LaBarge and Mina Bissell, in the national laboratory of Lawrence Berkeley, Berkeley.

It is not a AKT: the genetic variation affects the region of the disfuncional brain in the schizophrenia

The new data, generated by Daniel Weinberger and colleagues, in the national justinian codes of the health, Bethesda, had indicated that in healthful individuals, the variation in a known gene as AKT1 affects the structure and the function of the part of the brain that is disfuncional in the individuals with schizophrenia. Specifically, in healthful individuals, a particular variation AKT1 was associated with the damaged cognition (an ability damaged to the process information), something that is affected marked in the individuals with schizophrenia. Beyond, same variation AKT1 was associated with the diminished volume of the gray-substance in the frontostriatal region of the brain, that is disfuncional in the individuals with schizophrenia. A additional analysis indicated that variation AKT1 estve associated with an increased risk of schizophrenia and the therapeutical implications of this, as well as the other results of the study, is argued in a commentary of accompaniment for Alexander Arguello and Joseph Gogos, in the college of the University of Columbia of the doctors and the surgeons, New York.

OFTALMOLOGIA: Sight of a new perspective in drugs to correct a cause of the loss of the vision

A frequent complication in the individuals with diabetes in the long run is retinopathy of the diabetic one, an eye condition that is the root cause of the blindness in the adults of the propitious age for the work. A factor that contributes to the loss of the vision is the accumulation of liquid in the retina of the eye because the sanguineous vases in the retina if had become permeveis more. The new data, suggesting that a family of the known drugs as vasoinhibins retinopathy of the diabetic one could supply a new approach to diminish the permeability in the sanguineous vases of the eye of the individuals, had been generated in the rats for Carmen Clapp and colleagues, of the Autonomous National Universidad of Mexico.

Vasoinhibins opposes a known molecule as VEGF, that is an important starter of the increased permeability of the sanguineous vase in the retina of the individuals with retinopathy of the diabetic one. In the study, the injection of vasoinhibins in the eye was found to obstruct increases in the permeability of the sanguineous vase in the eye of rats of the diabetic one and to obstruct increases in the permeability of the sanguineous vase in the eye of the normal rats injected (in the eye) with the VEGF or the liquid of the eye of an individual with retinopathy of the diabetic one. Vasoinhibins had been shown to Mechanistically to the work activating a known protein as PP2A, that, in turn, inactivated a known protein as eNOS.

IMUNOLOGIA: A new target for the imunoterapia of the tumor in stacks dendritic?

Many investigators are interested in approaches becoming to induce the antitumorosas immune answers carried through by the known immune stacks as CTLs. In the rats, one-way to make that is to whiten proteins of the tumor to a subgroup of the known immune stacks as the stacks dendritic (DCS) that they express the CD8-alpha protein. That is because the DCS that express CD8-alpha can direct CTLs efficiently to attack all the proteins that will be whitened to them. A new way to whiten proteins of the tumor to the DCS that express CD8-alpha was discovered by Caetano Reis and Sousa and colleagues, in the United kingdom research of the cancer, the United kingdom, that they had identified a molecule whose the expression was restricted in the rats to the DCS that express CD8-alpha and one another subgroup of the known C.C as the DCS of plasmacytoid.

The functional studies had indicated that the molecule, that was nominated the group dendritic receiver-1 of lectin of stack NK (DNGR-1), was a receiver endocytic and that if an antibody that recognized DNGR-1 was lig to one peptide it delivered peptide specifically to the DCS that express CD8-alpha. The CTL answers had directed to peptide had been induced in the rats vacinados with the antibody peptide-lig of DNGR-1-specific and an adjuvant. To direct these answers of CTL for stacks of the melanoma lig the antibody of DNGR-1-specific to peptides of proteins overexpressed for an eradicated melanoma cellular line of the melanoma in a therapeutical model of the rat. More, as the expression of DNGR-1 in the human beings was found to be restricted to a subgroup of the DCS with the similar characteristics to the DCS of the rat that express CD8-alpha, the authors had suggested that this to whiten the DCS through DNGR-1 could supply a new approach to the imunoterapia of the tumor.

NEUROBIOLOGIA: To protect of meeting or to promote, that one is the question on the paper of the cellular process autophagy in the illness of Alzheimer

All the clutters neurodegenerative (for example illness of Alzheimer [ANNOUNCEMENT], illness of Parkinson, and illness of Huntington) are characterized by the presence of added of the protein in the death of stack of the brain and the nerve. The recent data had implied a known cellular process as autophagy (by means of that the stacks can degrade proteins and compartments long-lived to remodel its interiors and/or to survive the fatigantes situations) in neurodegeneration, but if it protects of meeting or it promotes neurodegeneration remains controversial. The data new, generated by Tony Wyss-Coray and colleagues, in the University of Stanford, had indicated that one diminished autophagy in stacks of nerve can increase neurodegeneration in a model of the rat of the ANNOUNCEMENT.

In the study, the rats that lack one of its Becn1 genes, that carreg the demanded information to make beclin autophagy key 1 of the protein, had been found to show the diminished stack of nerve autophagy and to this they had been associates with neurodegeneration increased. When a model of the rat of the ANNOUNCEMENT was projected similarly to lack a Becn1 gene, an increased amount of accumulation of neurodegeneration and of the protein in the brain it was observed. Inversely, if the model of the rat of the ANNOUNCEMENT was projected to express amounts increased of beclin 1, the diminished accumulation of the protein in the brain was observed. The authors suggest consequently that one the increasing levels of beclin 1 can be of the benefit to the individuals with ANNOUNCEMENT.

In a accompaniment commentary, Jin-Um Lee and fen-Biao Gao, in the University of California in San Francisco, writes down that even so to modulate levels of beclin 1 it can be a attractive approach to treat individuals with the ANNOUNCEMENT, studies more adds in other animal models is demanded for verific the viability of this strategy.

INFLAMMATION: Round Redondo and we go: bow of positive answer sheet proinflammatory identified in the intestines of the individuals with illness of Crohn

Although the illness of Crohn (COMPACT DISC) and colitits ulcerosos (UC) are both the types of the illness of viscera inflammatory (IBD), the mechanisms that are the base of these two illnesses are different. The new introspection in the inflammatory riots of the stack in the intestines of the individuals with COMPACT DISC was supplied by Toshifumi Hibi and colleagues, in the College of Medicine of the university of Keio, Japan, who had suggested that these changes could contribute to the development of the illness.

The majority of known immune stacks as the macrophages that live in the intestine does not express molecule CD14 and this characteristic proinflammatory is associates with a lack of the production of known factors as cytokines. In the study, an increased number of macrophages that they express CD14 (as well as other molecules expressed not generally for intestinais macrophages) was detected in the intestines of the individuals with the COMPACT DISC compared with the intestines of healthful individuals and those with UC. These stacks had produced great amounts of cytokines proinflammatory IL-23 and TNF-alpha, that had made with that other immune stacks in the area produced one another one cytokine proinflammatory, IFN-gamma. Because IFN-gamma was found to cause a later increase in the number of macrophages that express CD14 and that they produce IL-23, the authors suggest that IL-23 and IFN-gamma give form to a bow of positive answer sheet that promotes the inflammation in the intestine of the individuals with COMPACT DISC.

VIROLOGY: The stacks of T of CD4+ are really rest candy home for the relative of the monkey of the HIV

Many tensions of the monkey become of course contaminated with viruses that are related to the HIV. These viruses are known collectively because the SIV and the monkeys of course contaminated do not develop the AIDS. One expects that because the monkeys contaminated of course with SIV if do not become the comprehensive AIDS it could teach the investigating lies important on the mechanisms that are the base of the development of the AIDS in the contaminated human beings with HIV and to identify ways to hinder this event. The new introspection in the mechanisms that of course control the particle number of the virus in the blood of mangabeys sooty contaminated with SIVsmm, the tension of the SIV that contaminates mangabeys of course sooty, has been supplied now for a team of the investigators of the University of the Pensilvnia, the Philadelphfia, and the university of Emory, Atlanta.

The HIV and the SIV contaminate the known immune stacks as stacks of T of CD4+. Thus, the authors to display to determine as the stacks of T of CD4+ had of course affected the particle number of the virus in the blood of mangabeys sooty contaminated with SIVsmm - they had supplied the immune control of the particle number of the virus or them they had supplied a place simply to live one replicate. The particle number of SIVsmm in the blood of mangabeys sooty of course contaminated diminished when the monkeys had been depleted of stacks of T of CD4+ and had increased then another time while the number of proliferating stacks of T of CD4+ repercutiriu. Thus, a little of what was concluded that the availability of proliferating stacks of T of CD4+ is a determinative cause key how many particles of SIVsmm could be detected in the blood of mangabeys sooty of course contaminated, of the stacks of T of CD4+ that supply the immune control of the virus.

METABOLIC ILLNESS: The FoxO1 protein of the liver can lig overindulgence with the type - diabetes 2

The high levels of blood of known fats as triglycerides and triglyceride-rich molecule VLDL are factors of risk for the cardiac illness and diabetes. The VLDL production is dependent of the regulator of insulin of the levels of blood sugar (works to lower levels of blood sugar) and of protein MTP of the liver, these interactions are even so not understood well. In a new study, dong of Henry and its colleagues in the university of the College of Medicine of Pittsburgh had disclosed a relationship enters the FoxO1 protein of the liver and the superproduction of VLDL.

Using cellular line cultivated human beings of the liver, the investigators had shown that the FoxO1 limit and the stimulated expression of MTP and secretion inhibited of insulin. Consistent with this, overexpression of FoxO1 increased, and prostrao diminished FoxO1, levels of MTP and VLDL in the rats. Moreover, the rats with deficiencies in damage of triglycerides had equally had high levels of FoxO1 and VLDL. The authors conclude consequently that this relationship between FoxO1, insulin, and VLDL could explain, in the part, the simultaneous increases in the blood sugar and triglyceride is even at risk seen in the patients for the type - diabetes 2. A commentary of accompaniment for sparks of Janet and Charles in the university of the College of Medicine of Rochester concludes more than this study it establishes a linking between overindulgence dietary and the multiple clutters that for an individual in the increased risk to develop the type - diabetes 2, including the hipertenso, the obesidade, the high neses of the cholesterol, and the resistance to the effect of insulin.

A new report in the genetic test of the agency of HHS for calls of the research and the quality of medical cares for the creation of public databases improved of the sanitary control and the technologies of the information of the health to monitor the use of gene-base tests and its impact in patient results.

Financed for centers for the control and prevention of diseases, for the intitled report, the infrastructure to monitor the use and the results of Gene-base applications: An evaluation, found that the current systems of monitoring of the public health lack the capacity to monitor the use or the results of tests and gene-base treatments. The authors of the report had identified diverse limitations of existing potential solution and databases to surpass these limitations.

The investigators had agreed that the development of gene-base tests is taking the advantage to the evaluation of its exactness and clinical utility. the Gene-base tests can, in some cases, to help to in advance make the diagnosis of an illness, to improve the prediction of the risk, and the therapies of the target for both the traditional gene-base clutters as well as common crnicas illnesses. However, since all the tests and treatments are not waited to have the same amount of benefit, the connoisseurs had said that it is important to distinguish beneficial tests and treatments of that they have almost no benefit or that they can exactly harm the public.

Many gene-base tests are only recommended for peoples with determined risk factors. For example, the services that preventive of the E.U the work group recommends doctors of the primary attention must only consult women of high risk so that the genetic assistance and to test detects the genetic mutations associates with the ovarianos chest or cancers. The work group recommends that the women who do not have familiar antecedents of the chest or the ovariano cancer and are little susceptveis to test the positive for the mutations do not have to be consulted for the test, because she has potential harms involved in the genetic test that includes resulted of the analysis falsifies-positive. Equally, the work group recommends of meeting to the routine genetic election in the general population for hemocromatose hereditary, a genetic illness that makes with that the body absorbs and stores iron too much.

The best capacities of the monitorao would help to identify that gene-they had based tests they improve resulted patient and they are cost-effective, the joined investigators. In 2009, the world-wide market for the gene-base test is waited to alcangar $12,5 billion.

More than 1,000 gene-base tests are now available to the consumers through its physicians, and they are not waited to become in a next future available. Some of these tests are introduced in the market directly the consumers. The commission of federal commerce emitted an alert one of the consumer in the familiar genetic test and stirs up consumers to be skeptical of the claims made for the company that are introducing in the market these tests directly to the consumers. AHRQ recommends patients consults with its physicians to evaluate its factors of risk and to determine its necessity for the genetic test.

The immune stacks calls macrophages can destroy stacks of the tumor producing the inflammatory proteins that are toxic to the tumor. But the environment inside of the tumor stops in some way this production and makes with preferably that the stacks make the proteins that promote the growth of the tumor.

The new study it identifies a protein, call IKK (beta), that this interruptor of the pro-tumor leads. This protein stimulates the protective inflammation normally. But in the context of the tumors, the study it shows, IKK (beta) equally obstructed the activity of a protein that turns on antitumorosos genes.

When the scientists inactivated IKK (beta) in the macrophages of the tumors of the rat, the tumor-friendly stacks had been in the attack. These stacks had equally segregated the proteins that had attracted the professional stacks of the tumor-slaughter that they had helped to shrink the tumors. The investigators are leading clinical assays now to determine if the macrophages of the patients who you suffer from cancer similarly can reprogrammed in assassins of the tumor.

Many species participate in the version of the nature of the games of the rock-paper-shears, where the rock beats shears, paper of the strokes of the shears, and strokes of the paper balan. Because nobody type is better of what all the other, such games are a powerful force that promotes biodiversity.

A mathematical model of this situation discloses that with sexual reproduction and interactions with neighboring organisms - factors thought generally to promote the stability ecological - the games of the rock-paper-shears are only desestabilizados extremely, enhancing in this manner the risk of the extinguishing, and reducing biodiversity.

The scientists in the IFOM-IEO campus had disclosed the function of a protein that was indispensable to pass in an accurate copy of genome of the mother to the stacks of the son. This study, published in the stack, he opens above of the new avenues of the research reducing toxicity of chemotherapy in the treatment of cancer.

The protein can be compared with lasso of a cattle tender: constraint chromosomes and mooring cable them it a structure transitory mounted during the stack division. A time that had been moored ordenadamente above, chromosomes waits the extremity of replication to be distributed ingualmente enters the two stacks of the son. But if lasso not to stop them, chromosomes above finishes aleatria to be exhausted, with disastrous effect genetic potential: if the stacks to survive this, receive inheritance genetic wrong, with consequences dire. The structure and the function of this lasso chromosomal had been discovered in Milan, in the campus of IFOM-IEO (these hosts the laboratories of the institute of FIRC of molecular foundation IFOM of oncology and the European institute of oncology IEO) and these findings had been published only in the prestigious scientific periodical, stack. “we have studied a called molecule Ndc80 we explain Andrea Musacchio, main author of the study, and head of a group of research in the department of oncology experimental (IEO). This protein is a necessary player key for the correct distribution of inheritance genetic. Ndc80 could potential be used as a target for toxic the new drugs that would have few side-effects of that the current drugs, such as paclitaxel (called originally taxol), that they act mainly as inhibiting of replication of the stack.” The operative word is here ‘ mainly ‘. Although many used drugs in chemotherapy traditional act in the targets molecular that are in involved in the duplication of the stacks (during a known phase as ‘ mitosis ‘), these targets also have other cellular functions. Ndc80, in the other hand, only executes its work during the mitosis. Thus, obstructing Ndc80, the only stacks that would be affected would be dividing. All the other stacks would not be affected. Musacchio and its colleagues (together with the co-author PeterWulf and its team of research) are testing already a substance number that had been able to be able to obstruct the action of Ndc80. Findings published was a truily international effort that involves groups of research of England and U.S.A.; much of the work was made possible gratefulness to the financial sustentation of the Italian association for the research of cancer (AIRC).

TREATMENT Of the MITOSIS And the CHEMOTHERAPY FOR the CANCER

“we have studied the mechanisms that regulate the accurate duplication of genome per many years we explain Musacchio now. Our hope must discover new drugs, more less toxic for chemotherapy. The stacks of cancer grow in a much more fast tax of that the normal stacks and the traditional drugs of chemotherapy, as paclitaxel, obstructs this process of the stack division. Efficacy of these drugs depends on the differences in the taxes of growth of the normal one and the stacks on cancer. This means that paclitaxel is toxic for all the stacks that if they submit to the mitosis; however, since that the majority of stacks mitotic in patients of cancer is really stacks of cancer, it follows that this drug will make the majority of its damages in stacks of cancer. The problem is that paclitaxel acts in the proteins that are essential not only so that the stacks if they divide, but also for other phases of the cycle of the stack. This means that the drug has toxicity associated significant, something that we would prevent to rather. We hypothesized that Ndc80 was only active during the stack division, that is because we think that he could be an interesting target to study. E our results had proved them for the right. We discover that Ndc80 acts as a type of lasso molecular that tethers chromosomes to the axle mitotic, a molecular structure this only gives form during the mitosis. Chromosomes of the Ndc80 braces firmly in the axle until the dividing stacks separates; after this period of training, is not of not more use to the stack. Thus, if we to intervene with the Ndc80, us we can significantly reduce ‘ the window so-called of toxicity ‘.” All the drug that to inhibit the function of Ndc80 would be consequently much specific tumor-more of that currently available treatments. “PeterWulf and I continue Musacchio have celebrated already some interesting molecules. Ours inside work of vitro needs now to be validated in living creature, first in models of the laboratory, and then in clinical experimentations standard.”

STRATEGY IN CHANGE: OF TARGETS THERAPEUTIC TO DRUGS THERAPEUTIC

Musacchio and the colleagues had made a forward important stage in understanding the functionings molecular of the normal one and the stacks of cancer. This work is the point to start for the development of new drugs. But, as this scientist indicates, the needed skill to obtain this last stage is lacking sorely in Italian environments academic of the research. “the development of the new drug explains Musacchio depends on the mutual interaction of chemistries and the biologists. The Italian research academic still not capitalized in this, and the academy limits it the identification of targets therapeutic. When this will be a necessary stage and important, the development of new drugs is left in the great hands of the pharmaceutical company.”

This situation is unacceptable. The Italian research academic (that, for the free definition, and lucr-no is lead) can and must also focus in selecting for the molecules that can interact with the new-identified targets to inhibit them. To add to the insult the wound, such composites are neglected frequent by pharmaceutical company, when they do not fall inside of its strategies of the production. Musacchio and the strategy of Of Wulf in its hunting for the molecules that can inhibit Ndc80, exemplifies what it needs to be made. But, unhappyly, its approach is not adopted generally in Italy, and the opening between the basic and translational or applied research always grows wider. Musacchio uses a vivid metaphor to describe the situation: “we discover mountains to scale, but we do not have the needed equipment to guarantee the success of our expeditions”. We do not have underestimate the value of the collections of composites hidden moved away in laboratories from chemistry academic; these could be public available facts. Mussacchio concli: “a contribution of this type would be invaluable for the international research and a culminating accomplishment for our nation”.

Because the foundation of Nobel recognizes 55th anniversary of the discovery of the structure of the DNA, the society recently given form of Rosalind Franklin commemorates the contribution of the behind Rosalind Franklin, whose the data crystallographic had made this possible discovery.

Although Franklin is not enclosed in the prize of Nobel granted to crick been slow of Francis, the behind Maurice Wilkins, and the James Watson to decide the structure of the DNA, today the importance and the beauty of its work are recognized in almost each general modern molecular biology and textbook of biology. The purpose of the society of Rosalind Franklin is to promote one recognition greater of the prominent contributions made by women to life sciences. Since the start of Nobel in 1901, 12 prizes only are of 419 had been given to the women in sciences (physical, chemistry, and medicine). Because the foundation of Nobel rejoices in the discovery that was recognized for the 1962 prize, us we wait that they make examination of this chance to appropriately also recognize the contributions seminal of the Dr. Franklin.

The society of Rosalind Franklin stirs up the foundation of Nobel to consider recognition future of more of the truily great scientists of the women of century XXI.

the investigators Kingdom Join-based in the functional unit of Genomics of the advice of medical research in Oxford and the European institute molecular European of Bioinformatics of laboratory of biology in Cambridge had disclosed to the composition genetic of this of the most strange mammals of the world. They had analyzed blueprint of platypus, one of the DNA of some you only monotremble to survive that, of all the mammals, are the distantone related to the human beings. Platypus, a female nicknamed Glennie, was arranged in sequence for scientists in genome that it arranges in sequence the center of the school of the university of Washington of the medicine, of U.S.A. as the part of an international contribution of the research including scientists of the Joined Kingdom and Australia. The analysis is published in the introduction of 8 May of the nature.

Platypus is thought for diverged of a common ancestor shared with 170 human beings approximately million years has. The species has many characteristics that are original to the mammals; for the example it has the skin and it raises its young in milk. However, it also shows reptile-as characteristic; the females place eggs and the males produce venom. Some characteristics, such as a system specialized in the account of platypus that it uses the electricity to detect the food under the water (electro-reception), are original to monotremble them. The investigators had found that these diverse characteristics are espelhadas by one patchwork of the genes that if are similar to those of the reptiles, the birds and the other mammals. The investigator Chris Ponting of the linking of the functional unit of MRC Genomics in the university of said Oxford “genome of platypus is extremely important because it is the missing linking in our understanding of as we and other mammals evolves first. This is our back part of the ticket the time when all the mammals had placed eggs to suckling its young in milk. It also supplies a deep essential to the future advances in understanding biology and the evolution mammalian.”

The investigators procurararam genome for the sequences of the DNA that is original to monotrembles them, as.well.as those known to be involved in the production of venom, the electro-reception and the milk production in the other species. They had discovered that venom of platypus is a cocktail of the proteins that had had very different functions originally. Surprising, the same proteins are found in venom of the same reptile that venom of platypus and the serpent evolves independently. They had also found that platypus more has much chromosomes of the sex - the organized structures where the DNA is packed that it determines the sex - of that human beings. Platypus has ten chromosomes of the sex, compared with ours two. Moreover, the responsible sequences of the gene to determine the sex are more similar to those in the birds of that in the mammals. Ewan Birney, that lead to the analysis of genome executed in the European institute of Bioinformatics, commented “the looks of platypus as a mixture so stranger of mammalian, bird-as and characteristics reptilian and now we know that genome is a mixture ingualmente bizarre of all to these. Mlange of that is much more of one any one waited.”

The investigators in the institute of cancer of OR had identified a new gene that caused cancer. The research land-breaking appears monday in the Oncogeneperiodical of cancer of the nature.

The gene and its protein, both called RBM3, are vital for the division of stack in normal stacks. In cancers, the low levels of the oxygen in tumors make with that the amount of this protein goes above dramtica. This makes with that the stacks of cancer divide uncontrollably, leading to the increased formation of the tumor.

The investigators had used the new powerful technology “to silence” the protein and to reduce genetically the level of RBM3 in stacks cancerous. The approach stopped cancer of the growth and lead it it the death of the stack. The new technique was successfully tested in diverse types of cancers - chest, pancreas, colon, lung, ovarian and prostate.

“we are excited on this discovery because the majority of cancers is thought to come of mutations in the genes, and our studies, for the first time, we had shown that too much of this type of protein he makes with really that the normal stacks turn in stacks of cancer,” Shrikant cancer of in the project had said Anant of cancer in the institute of main investigator OR and a biologist, Ph.D..

Anant said that they had found protein RBM3 in each period of training of many cancers, and the amount of increased protein as cancer grew. The protein helped cancer to grow more quickly, prevents the death of the stack and was party to suit that gave to form the new boats of blood to feed the tumor.

“this process, called angiogenesis, is essential for the growth of the tumor and suggests perhaps that this to whiten RBM3 can be an extremely powerful tool of continuous meeting to many and to all tumors,” said Anant.

One room to finance for the research of cancer comes of a concession $800,000 of the national justinian codes of the health with the deep remains of the university of the college of Oklahoma of the medicine. The following stage for Anant, Dr. Courtney Houchen and its team of research in the center of sciences of the health of OR is to develop the agents who obstruct the function of the protein in a variety of cancers. The investigators wait to start clinical experimentations in OR approximately five years.

The Dr. Eric Fombonne, of the institute of research of the MUHC in the hospital of the children of Montreal, is involved in one consortium of the multi-place to collect samples of the DNA of 2.000 patients of autism and its families on the three following years.

The simple collection of Simons (SSC) is a coordinate effort to create a database of the information genetic and behavioral on the cases where it only has a member of the family with autism. This group, that represents the great majority of disorders of spectrum of autism, expects to lead to the discovery of the new factors genetic that they increase the risk of autism.

Beyond, this database will be accessible in line for the scientific community and will represent a tool invaluable for the future projects of research.

“this database will bind to the advanced analysis genetic to the evaluations behavioral very detailed. This is a project unprecedented that it could extremely enhance our understanding of underlying biological processes, “explains the Dr. Fombonne. “this is an important stage for unraveling of mechanisms genetic and the understanding of pathophysiology of this disorder of the development of the brain.”

The families currently are being enlisted to participate in an initial evaluation and then they can be invited to participate in other projects of research while the work continues. Those eligible ones to participate are families with only a child with disorder of spectrum of autism (ASD) that it is four years of age or older; with one or more siblings without a ASD, ages the four or oldest one; e biological parents without a ASD and who is made use to participate. The eligible children with a ASD will receive an evaluation behavioral and all the members of the family will donate the blood, a source of the DNA. A small number of the families with nenhuns siblings or siblings under the age of four can be eligible to participate in the study.

“the MUHC is committed to enlist 200 families for the 2009 end. This represents an important challenge, but being the only center in Canada we wait to be able to attract the required number of English talkative patients, “we say the Dr. Fombonne.

Beyond to the research institute of the MUHC, the SSC will be lead in the university of Baylor, in the university of Colombia, the university of Emory, the university of Harvard, the university of California, Los Angeles (UCLA), in the university of Illinois-Chicago, the university of Michigan, the university of Missouri, the university of Washington, the university of Vanderbilt, the university of Washington, and the university of Yale.
