CD98hc molecule appears to be necessary for rapid and effective skin renewal

These mechanisms, described in vivo in mice, engage molecule CD98hc, which is involved in epidermis renewal and could be an indicator of the skin's capacity for regeneration.

EBV reactivation can increase risk of heart disease

A new study could provide the link that scientists have been looking for to confirm that reactivation of a latent herpes virus is a cause of some heart problems.

Studies identify cellular pathways involved in governing day-night pattern of circadian rhythms

UC Irvine-led studies have revealed the cellular mechanism by which circadian rhythms - also known as the body clock - modify energy metabolism and also have identified novel compounds that control this action. The findings point to potential treatments for disorders triggered by circadian rhythm dysfunction, ranging from insomnia and obesity to diabetes and cancer.

Multiple vascular benefits in salt restriction

Restricting salt intake reverses vascular endothelial dysfunction in people with moderately increased blood pressure, shows a randomized study published in the Journal of the American College of Cardiology.

Studies suggest a new approach to treating HIV

A team of researchers based at Johns Hopkins has decoded a system that makes certain types of immune cells impervious to HIV infection.

Scientists discover role of OTUD7B enzyme as TRAF3's protector

Marked for death with molecular tags that act like a homing signal for a cell's protein-destroying machinery, a pivotal enzyme is rescued by another molecule that sweeps the telltale targets off in the nick of time.

Scientists identify a possible lead in treatment of two childhood leukemia subtypes

Research led by St. Jude Children's Research Hospital scientists has identified a possible lead in treatment of two childhood leukemia subtypes known for their dramatic loss of chromosomes and poor treatment outcomes.

Possible connection between mitochondrial CYP2D6 and Parkinson's

With a new insight into a model of Parkinson's disease, researchers from the University of Pennsylvania School of Veterinary Medicine have identified a novel target for mitigating some of the disease's toll on the brain.

Lack or excess of CaM kinase II affects heart muscle cell stiffness

A certain enzyme, the CaM kinase II, keeps the cardiac muscle flexible. By transferring phosphate groups to the giant protein titin, it relaxes the muscle cells. This is reported by researchers led by Prof. Dr. Wolfgang Linke of the Institute of Physiology at the Ruhr Universität in the journal Circulation Research. In failing hearts, which don't pump enough blood around the body, the scientists found an overly active CaM kinase II.

MPL vaccine can stimulate brain's natural defense mechanisms in people with AD

A team of researchers from Universit- Laval, CHU de Qu-bec, and pharmaceutical firm GlaxoSmithKline (GSK) has discovered a way to stimulate the brain's natural defense mechanisms in people with Alzheimer's disease.

New menu of 61 genetically engineered E. coli strains may improve efficacy of vaccines

Researchers at The University of Texas at Austin have developed a menu of 61 new strains of genetically engineered bacteria that may improve the efficacy of vaccines for diseases such as flu, pertussis, cholera and HPV.

Scientists identify new mechanism for schistosomiasis-bladder cancer connection

About 200 million people across 75 of the poorest countries in the world are now infected by the blood parasite Schistosoma haematobium (S. haematobium). The infection causes severe urogenital disease, but also causes bladder cancer in a number of patients and why this occurs is not clear.

SF3B1 gene mutations in uveal melanoma linked to favorable features

Melanomas that develop in the eye often are fatal. Now, scientists at Washington University School of Medicine in St. Louis report they have identified a mutated gene in melanoma tumors of the eye that appears to predict a good outcome.

Scientists determine structure of Ltn1 protein

Using an innovative approach, scientists at The Scripps Research Institute (TSRI) have determined the structure of Ltn1, a recently discovered "quality-control" protein that is found in the cells of all plants, fungi and animals.

Blocking cholesterol biosynthesis pathway in cancer cells appears to improve ability of common drugs

Shutting down a specific pathway in cancer cells appears to improve the ability of common drugs to wipe those cells out, according to new research from scientists at Fox Chase Cancer Center, published in the January issue of Cancer Discovery.

New system based on photonic biosensors can rapidly diagnose food allergies

Researchers at the Institute of Materials Science of the Universitat de València, in consortium with various European companies and institutions, are developing a system based on photonic biosensors for rapid diagnosis of food allergies.

Clathrin protein may have a role in suppressing tumors

Newly published research by Indiana University structural biologist Joel Ybe and colleagues identifies a "topology switch" in the protein clathrin, the function of which may shed light on molecular processes involved in tumor suppression.

p53 activation suppresses malic enzyme expression and leads to senescence in pre-cancerous cells

It is perhaps impossible to overstate the importance of the tumor suppressor gene p53. It is the single most frequently mutated gene in human tumors. p53 keeps pre-cancerous cells in check by causing cells, among other things, to become senescent - aging at the cellular level. Loss of p53 causes cells to ignore the cellular signals that would normally make mutant or damaged cells die or stop growing.

Aggressive breast cancer’s metastasis molecular switch identified

Scientists at Weill Cornell Medical College have discovered the molecular switch that allows aggressive triple negative breast cancer cells to grow the amoeba-like protrusions they need to crawl away from a primary tumor and metastasize throughout the body. Their findings, published in Cancer Cell, suggest a novel approach for developing agents to treat cancer once it has spread.

UCSF teams to study new ways to reduce childhood mortality and disease in developing nations

Two UCSF teams have received a total of $16 million from the Bill & Melinda Gates Foundation to study new ways to significantly reduce childhood mortality and disease in developing nations.
