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.

Prenatal brain development may be important influence on psychiatric risk later in life

Some brain changes that are found in adults with common gene variants linked to disorders such as Alzheimer's disease, schizophrenia, and autism can also be seen in the brain scans of newborns.

TFP5 molecule restores memory in mice with Alzheimer's

A new ray of hope has broken through the clouded outcomes associated with Alzheimer's disease. A new research report published in January 2013 print issue of the FASEB Journal by scientists from the National Institutes of Health shows that when a molecule called TFP5 is injected into mice with disease that is the equivalent of human Alzheimer's, symptoms are reversed and memory is restored-without obvious toxic side effects.

Fructose linked to food-seeking behavior and food intake

In a study examining possible factors regarding the associations between fructose consumption and weight gain, brain magnetic resonance imaging of study participants indicated that ingestion of glucose but not fructose reduced cerebral blood flow and activity in brain regions that regulate appetite, and ingestion of glucose but not fructose produced increased ratings of satiety and fullness, according to a preliminary study published in the January 2 issue of JAMA.

Study identifies mechanism by which bacterium S. aureus colonizes nasal passages

A collaboration between researchers at the School of Biochemistry and Immunology and the Department of Microbiology at Trinity College Dublin has identified a mechanism by which the bacterium Staphylococcus aureus (S. aureus) colonizes our nasal passages. The study, published today in the Open Access journal PLOS Pathogens, shows for the first time that a protein located on the bacterial surface called clumping factor B (ClfB) has high affinity for the skin protein loricrin.

Common cholesterol-lowering drug may help protect against cerebral malaria

Researchers have discovered that adding lovastatin, a widely used cholesterol-lowering drug, to traditional antimalarial treatment decreases neuroinflammation and protects against cognitive impairment in a mouse model of cerebral malaria.

Hepatitis C virus takes over invaded cell by hijacking protein making machinery

Researchers at the University of Colorado School of Medicine have figured out intimate details of how the hepatitis C virus takes over an invaded cell, a breakthrough that could point to way for new treatments for the virus.

Scientists identify molecular mechanism central to development of osteoarthritis pain

Researchers at Rush University Medical Center, in collaboration with researchers at Northwestern University, have identified a molecular mechanism central to the development of osteoarthritis (OA) pain, a finding that could have major implications for future treatment of this often-debilitating condition.

Manipulating transcription factor can change subtype of breast cancer

Australian scientists have shown how a 'transcription factor' causes breast cancer to develop an aggressive subtype that lacks sensitivity to oestrogen and does not respond to anti-oestrogen therapies such as Tamoxifen and aromatase inhibitors.
