Researchers identify first gene mutation associated with chronic, often fatal form of neuroblastoma

Researchers have identified the first gene mutation associated with a chronic and often fatal form of neuroblastoma that typically strikes adolescents and young adults. The finding provides the first clue about the genetic basis of the long-recognized but poorly understood link between treatment outcome and age at diagnosis.

Gene simultaneously protects against and also promotes cancer growth

Can a gene simultaneously protect against cancer and favor its growth? Researchers at the Spanish National Cancer Research Centre have discovered a gene with this double-edged property and suspect there may be many more that share it. In the words of Oscar Fernandez Capetillo, head of the group responsible for the study, this gene "can be both Dr. Jekyll and Mr. Hyde, in that it can either protect us against the appearance of tumors or promote tumor growth".

Researchers crack problem of predicting gene targets for PcG proteins

Cancer is usually attributed to faulty genes, but growing evidence from the field of cancer epigenetics indicates a key role for the gene "silencing" proteins that stably turn genes off inside the cell nucleus. A new study from Rice University and Baylor College of Medicine promises to speed research in the field by rapidly identifying the genes that epigenetic proteins can target for silencing.

Researchers discover over 500 genes that may contribute to pancreatic cancer

A global team led by scientists from The Methodist Hospital Research Institute has identified more than 500 genes that may cause or contribute to the development of pancreatic cancer.

Majority of physicians utilize genetic testing, finds report

A new report by UnitedHealth Group's Center for Health Reform & Modernization finds that a majority of physicians are utilizing genetic testing. The report, titled "Personalized Medicine: Trends and prospects for the new science of genetic testing and molecular diagnostics," presents new findings on how genetic tests can help diagnose disease, target prevention, and ensure that patients receive the medicines that will best treat their conditions.

Salk scientists' discovery explains how a class of chemotherapy drugs works

The well-being of living cells requires specialized squads of proteins that maintain order. Degraders chew up worn-out proteins, recyclers wrap up damaged organelles, and-most importantly-DNA repair crews restitch anything that resembles a broken chromosome. If repair is impossible, the crew foreman calls in executioners to annihilate a cell. As unsavory as this last bunch sounds, failure to summon them is one aspect of what makes a cancer cell a cancer cell.

Chlamydia has evolved more actively than previously thought

In a study released today in Nature Genetics, researchers have found that Chlamydia has evolved more actively than was previously thought. Using whole genome sequencing the researchers show that the exchange of DNA between different strains of Chlamydia to form new strains is much more common than expected.

HIPK2 regulator protein plays a crucial role in kidney fibrosis

Researchers from Mount Sinai School of Medicine have identified a regulator protein that plays a crucial role in kidney fibrosis, a condition that leads to kidney failure. Finding this regulator provides a new therapeutic target for the millions of Americans affected by kidney failure. The research is published in the March 11 issue of Nature Medicine.

Conference highlights studies on metabolism, aging and monarch butterfly migration

The Genetics Society of America's 53rd Annual Drosophila Research Conference, March 7-11 at the Sheraton Chicago Hotel & Towers, will showcase diverse efforts to understand basic biological processes through the easy-to-study fruit fly, Drosophila melanogaster, and other insects.

Five new genetic mutations linked with Crohn's disease in Ashkenazi Jews

In the largest study of its kind, researchers from Mount Sinai School of Medicine have discovered five new genetic mutations associated with Crohn's disease in Jews of Eastern European descent, also known as Ashkenazi Jews.

Researchers identify specific gene linked with throat cancer

Researchers at King's College London and Hiroshima University, Japan, have identified a specific gene linked to throat cancer following a genetic study of a family with 10 members who have developed the condition.

Do we age as a consequence of being protected against cancer?

The role of one of our genes which protects us from cancer but could also cause us to age will be explained in a lecture at the University of Leicester.

Scientists believe that ageing can be programmed in the womb

Ageing is a complex process involving physical, psychological, and environmental factors. Scientists believe that ageing can be programmed in the womb. One example of stress during pregnancy is the administration of glucocorticoids, i. e. synthetic stress hormones to accelerate fetal lung maturation in premature labor to allow breathing after birth. Could exposure to these stress hormones have an effect on health later in life?

First ever analysis of genetic variation between different regions of same tumour

Taking a sample from just one part of a tumour may not give a full picture of its 'genetic landscape', according to a landmark study published in the New England Journal of Medicine.

NCGR to host eighth annual NMBIST symposium on March 22-23, 2012

The National Center for Genome Resources (NCGR) announced today that it will host the eighth annual New Mexico Bioinformatics, Science and Technology (NMBIST) symposium on March 22-23, 2012.

Novel set of genes linked with epithelial ovarian cancer patient survival

Researchers at Moffitt Cancer Center and colleagues from 11 other institutions in the United States and the United Kingdom have used two genome-wide association studies (GWAS) - one from the U.S. and one from the U.K. - to detect a novel set of genes found to be associated with epithelial ovarian cancer patient survival.

Researchers reveal how melanoma develops resistance to Zelboraf

Cancer is tough to kill and has many ways of evading the drugs used by oncologists to try and eliminate it. Now, researchers at UCLA's Jonsson Comprehensive Cancer Center have uncovered how an advanced form of melanoma gets around an inhibitor, Zelboraf, which targets the mutated BRAF gene.

New DNA-reading technology could lead to correct genetic diagnosis for muscle-wasting diseases

Scientists at The University of Nottingham have used a revolutionary new DNA-reading technology for a research project that could lead to correct genetic diagnosis for muscle-wasting diseases.

New, freely available Web-based program helps predict effect of mutations on mRNA splicing

In a brief paper in the journal Bioinformatics, Brown University researchers describe a new, freely available Web-based program called Spliceman for predicting whether genetic mutations are likely to disrupt the splicing of messenger RNA, potentially leading to disease.

PGen study to examine impact of consumer genomics

As genetic risk information plays an increasingly important role in the diagnosis and treatment of many diseases, private companies have made personal genomic testing for these risk factors widely available to the public. However, very little data has been gathered to understand the motivations and expectations of consumers of personal genomic services, the psychological and behavioral impact of these services, and the associated ethical, legal and social issues-until now.
