PSCA gene’s rs2294008 variant on T nucleotide may increase risk of bladder cancer

Patients who have inherited a specific common genetic variant develop bladder cancer tumors that strongly express a protein known as prostate stem cell antigen (PSCA), which is also expressed in many pancreatic and prostate tumors, according to research at the National Institutes of Health.

Chromatin regulation not governed by a uniform histone code

In a novel use of gene knockout technology, researchers at the University of California, San Diego School of Medicine tested the same gene inserted into 90 different locations in a yeast chromosome - and discovered that while the inserted gene never altered its surrounding chromatin landscape, differences in that immediate landscape measurably affected gene activity.

Statin therapy affects muscles’ energy production

Up to 75 per cent of patients who take statins to treat elevated cholesterol levels may suffer from muscle pain. Scientists at the Center for Healthy Aging at the University of Copenhagen have now identified a possible mechanism underlying this unfortunate side effect.

New insight into 22q11.2 deletion syndrome

Research out of the George Washington University (GW), published in the journal Proceedings of the National Academy of Sciences (PNAS), reveals another piece of the puzzle in a genetic developmental disorder that causes behavioral diseases such as autism.

New rat model simulates traumatic or surgical muscle tissue loss in humans

Penetrating soft tissue injuries that may be caused by bullet wounds or motor vehicle accidents, or exposure to explosive devices in military settings, can cause muscle loss resulting in functional disability and cosmetic deformity. Efforts underway to develop tissue engineering solutions to repair and replace damaged and lost muscle will benefit greatly from the availability of robust animal models to test these innovative therapeutic strategies.

Calphotin essential in keeping cellular calcium concentration low

All living cells keep their cellular calcium concentration at a very low level. Since a small increase in calcium can affect many critical cellular functions (an elevated calcium concentration over an extended period can induce cell death), powerful cellular mechanisms ensure that calcium concentration quickly returns to its low level.

Mayo Clinic researchers identify new target to improve treatment of pancreatic cancer

Researchers at Mayo Clinic in Florida have identified a new target to improve treatment of pancreatic ductal adenocarcinoma cancer, which accounts for more than 95 percent of pancreatic cancer cases. This fast-growing, often lethal cancer is resistant to conventional chemotherapy.

Scientists discover process by which mda-9/syntenin contributes to melanoma metastasis

After recently announcing success in eliminating melanoma metastasis in laboratory experiments, scientists at Virginia Commonwealth University Massey Cancer Center have made another important discovery in understanding the process by which the gene mda-9/syntenin contributes to metastasis in melanoma (the spread of skin cancer) and possibly a variety of other cancers.

New technique can precisely add or delete genes in living cells

Researchers at MIT, the Broad Institute and Rockefeller University have developed a new technique for precisely altering the genomes of living cells by adding or deleting genes.

DRD4 7R allele can contribute to longevity

A variant of a gene associated with active personality traits in humans seems to also be involved with living a longer life, UC Irvine and other researchers have found.

Scientists demonstrate importance of Plvap gene in mammalian physiology

Dartmouth scientists have demonstrated the importance of the gene Plvap and the structures it forms in mammalian physiology in a study published in December by the journal Developmental Cell.

Researchers analyze impact of 3 unexpected sex determination factors

So, is it a girl or a boy? This is the first question parents ask at the birth of an infant. Though the answer is obvious, the mechanism of sex determination is much less so. Researchers at the University of Geneva (UNIGE) attempt to shed light on this complex process by identifying the crucial role played by insulin and IGF1 and IGF2 growth factors, a family of hormones known for its role in metabolism and growth.

Itch-specific nerve cells in skin discovered by John Hopkins scientists

Johns Hopkins researchers have uncovered strong evidence that mice have a specific set of nerve cells that signal itch but not pain, a finding that may settle a decades-long debate about these sensations, and, if confirmed in humans, help in developing treatments for chronic itch, including itch caused by life-saving medications.

Trovagene, MD Anderson partner to detect transrenal BRAF mutations in metastatic cancers

Trovagene, Inc., a developer of transrenal molecular diagnostics, announced that it has entered into a clinical collaboration with The University of Texas MD Anderson Cancer Center to detect transrenal BRAF mutations in the urine of patients with advanced or metastatic cancers.

CXCR5 molecule effectively polices lung tuberculosis and prevents deadly infection

The presence of a certain molecule allows the immune system to effectively police tuberculosis (TB) of the lungs and prevent it from turning into an active and deadly infection, according to a new study led by researchers at Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh School of Medicine.

Gut bacterial communities play an integral role in protecting against human intestinal disorders

Instability in the composition of gut bacterial communities (dysbiosis) has been linked to common human intestinal disorders, including inflammatory bowel disease and colorectal cancer; however, it is unclear if dysbiosis can instigate disease or if it is a consequence of the underlying disorder.

Improving research on BPA chemical may lead to better guidelines for human health

Following a three-year study using more than 2,800 mice, a University of Missouri researcher was not able to replicate a series of previous studies by another research group investigating the controversial chemical BPA. The MU study is not claiming that BPA is safe, but that the previous series of studies are not reproducible.

Molecular signals make some women prone to miscarriage

Scientists have identified molecular signals that control whether embryos are accepted by the womb, and that appear to function abnormally in women who have suffered repeated miscarriages.

Electroconvulsive therapy releases opiate-like substances

Researchers used electricity on certain regions in the brain of a patient with chronic, severe facial pain to release an opiate-like substance that's considered one of the body's most powerful painkillers.

Deimination restores inner retinal visual function in murine demyelinating disease

Demyelinating diseases, such as multiple sclerosis (MS), are frequently associated with the progressive loss of vision. The retinal nerve damage is thought to be caused by immune system-mediated inflammation; however, other demyelinating disorders, such as Pelizaeus-Merzbacher disease, do not involve the immune system, suggesting that there are other causes of retinal nerve damage.
