Study identifies regions of genes linked to Beh-et's disease

Researchers don't know the exact cause of Beh-et's disease, a chronic condition that leads to oral and genital sores and serious complications such as blindness, but new research brings better understanding to what makes some people more susceptible to being affected.

Researchers discover SCANR that helps protect a cell's genes against DNA interlopers

Gene wars rage inside our cells, with invading DNA regularly threatening to subvert our human blueprint. Now, building on Nobel-Prize-winning findings, UC San Francisco researchers have discovered a molecular machine that helps protect a cell's genes against these DNA interlopers.

University of Utah geneticists engineer mice that develop clear cell sarcoma

Geneticists led by University of Utah Nobel Prize Laureate Mario R. Capecchi, Ph.D., have engineered mice that develop clear cell sarcoma (CCS), a significant step in better understanding how this rare and deadly soft tissue cancer arises. The mouse model also can potentially speed the development of drugs to target genes that must be activated for the cancer to form.

Two different mechanisms trigger early-onset prostate cancers

While prostate cancer is the most common cancer in elderly Western men it also, but more rarely, strikes patients aged between 35 and 50. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, in collaboration with several other research teams in Germany, have discovered that such early-onset prostate cancers are triggered by a different mechanism from that which causes the disease at a later age.

Key details of how TRF2 protein performs crucial chromosome-protecting function

We take it for granted that our chromosomes won't stick together, yet this kind of cellular disaster would happen constantly were it not for a protein called TRF2. Now, scientists at The Scripps Research Institute (TSRI) have discovered key details of how TRF2 performs this crucial chromosome-protecting function.

Migraine, epilepsy and genetics: an interview with Dr. Melodie Winawer

This work is the product of an extraordinary consortium called the Epilepsy Phenome/Genome project (EPGP). It is a consortium of 27 centres in the U.S. and internationally with several hundred physicians and staff who have worked together to enrol more than 4000 patients with epilepsy and their family members.

UPCI researchers uncover new technique to stop growth of cancer cells

University of Pittsburgh Cancer Institute (UPCI) researchers have uncovered a technique to halt the growth of cancer cells, a discovery that led them to a potential new anti-cancer therapy.

Cells lose ability to defend against transposons as they age

Even in our DNA there is no refuge from rogues that prey on the elderly. Parasitic strands of genetic material called transposable elements - transposons - lurk in our chromosomes, poised to wreak genomic havoc. Cells have evolved ways to defend themselves, but in a new study, Brown University researchers describe how cells lose this ability as they age, possibly resulting in a decline in their function and health.

Brandeis University researchers to receive Wiley Prize in Biomedical Sciences

Deborah E. Wiley, Chair of The Wiley Foundation, John Wiley & Sons, Inc., announced today that the twelfth annual Wiley Prize in Biomedical Sciences will be awarded to Dr. Michael Young, Rockefeller University, Dr. Jeffrey Hall, Brandeis University (Emeritus), and Dr. Michael Rosbash, Brandeis University.

Study demonstrates new fragile genomic sites responsible for chromosomal alterations in tumors

Cancer arises from the accumulation of mutations and structural changes in chromosomes, which in some cases give rise to combinations that favour the growth or expansion of the disease. In this context, chromosomes tend to lose or duplicate entire regions, although, the mechanisms that initiate these chromosomal abnormalities are not fully understood.

C. albicans capable of sexual reproduction

Like many fungi and one-celled organisms, Candida albicans, a normally harmless microbe that can turn deadly, has long been thought to reproduce without sexual mating. But a new study by Professor Judith Berman and colleagues at the University of Minnesota and Tel Aviv University shows that C. albicans is capable of sexual reproduction.

Researchers identify mechanism by which vancomycin resistance spreads between bacteria

Worldwide, many strains of the bacterium Staphyloccocus aureus, commonly known as staph infections, are already resistant to all antibiotics except vancomycin. But as bacteria are becoming resistant to this once powerful antidote, S. aureus has moved one step closer to becoming an unstoppable killer.

Bipolar pedigree endophenotypes found

Researchers have found cognitive endophenotypes in a single extended family showing linkage of bipolar disorder to a risk locus on chromosome 4.

Telomerase gene mutation immortalizes deadly skin cancer

About ten percent of all cases of malignant melanoma are familial cases. The genome of affected families tells scientists a lot about how the disease develops. Prof. Dr. Rajiv Kumar of the German Cancer Research Center together with Prof. Dr. Dirk Schadendorf from Essen University Hospital studied a family where 14 family members were affected by malignant melanoma.

Novartis receives FDA approval for Ph+ acute lymphoblastic leukemia

The U.S. Food and Drug Administration today approved a new use of Gleevec (imatinib) to treat children newly diagnosed with Philadelphia chromosome positive (Ph+) acute lymphoblastic leukemia (ALL).

Genome sequencing data gives important clues on cancer

Genome sequencing data once regarded as junk is now being used to gain important clues to help understand disease.

Mice with reduced caloric intake accumulate longer telomeres

One of the indicators of a cell's health is the state of its DNA and containers-the chromosomes-so when these fuse together or suffer anomalies, they can become the source of illnesses like cancer and/or ageing processes.

Brown biology professor named Pew's Scholar of the Month

Biologist Erica Larschan, Ph.D., was named by The Pew Charitable Trusts as the "Scholar of the Month," for her innovative findings on chromosomal activity in fruit flies.

BRCA1-deficient cancer cells take advantage of DNA repair mechanism

Cancer cells are resourceful survivors with plenty of tricks for staying alive. Researchers have uncovered one of these stratagems, showing how cells lacking the tumor suppressor BRCA1 can resume one form of DNA repair, sparing themselves from stagnation or death. The study appears in the January 21st issue of The Journal of Cell Biology.

New details about molecular surveillance system that helps detect and correct errors in cell division

Studies led by cell biologist Thomas Maresca at the University of Massachusetts Amherst are revealing new details about a molecular surveillance system that helps detect and correct errors in cell division that can lead to cell death or human diseases. Findings are reported in the current issue of the Journal of Cell Biology.
