New findings could help scientists design more effective treatments to slow or halt the progression of HIV infection

Random fluctuations in gene expression can influence the fates of cells infected with human immunodeficiency virus (HIV) far more than previously thought, according to new research from Howard Hughes Medical Institute (HHMI) researchers at the University of California, Berkeley.

Valuable clues for rational antimalarial drug design and vaccine development

By determining the molecular structure of a protein that enables malaria parasites to invade red blood cells, researchers have uncovered valuable clues for rational antimalarial drug design and vaccine development. The findings are reported in the July 29 issue of the journal Cell.

New way to prevent macular degeneration

Two studies from an unusual research partnership at the University of Chicago appear to have resolved a long-standing dispute about the role of melanin in the eye. The studies, one published in the Proceedings of the National Academy of Sciences (PNAS) and one early online in the Journal of the American Chemical Society (JACS), also suggest a new way to prevent a common cause of blindness.

New insight into how protein E75 may control circadian rhythms and metabolic processes

University of Toronto researchers have gained new insight into how a specific protein may control circadian rhythms and metabolic processes, which has implications for treating cholesterol-related diseases.

Scientists discover genes linked to spread of breast cancer

In new research scientists have identified genes which enable breast cancer cells to spread to the lungs, and the discovery could very well improve diagnosis and treatment of the disease.

$4.7million grant for research on neuroblastoma

Significant funding from Australia's National Health and Medical Research Council will enable researchers at Children’s Cancer Institute Australia (CCIA) for Medical Research to make progress on the treatment of one the most aggressive, drug-resistant childhood cancers - neuroblastoma - over the next five years.

Bone marrow may be source of new egg-cell generation

Last year a group of Massachusetts General Hospital (MGH) researchers announced surprising findings that female mice - contrary to longstanding theories of mammalian reproductive physiology - retained the ability to make new egg cells or oocytes into adulthood.

Researchers make headway in mystery of migraines

The research, published in the new issue of the Proceedings of National Academy of Sciences (PNAS), reveals how gene mutations known to cause a form of inherited migraine target a cellular process involved in brain cell communication.

Revolutionary finding on female reproductive function

Previously unrecognized stem cells found in the bone marrow and blood of mice can "restock" a depleted ovary with new egg cells within weeks, according to new research published in this week's issue of the journal Cell.

Cancer biology, pharmacology and engineering combine to create cancer smart bomb

Imagine a cancer drug that can burrow into a tumor, seal the exits and detonate a lethal dose of anti-cancer toxins, all while leaving healthy cells unscathed.

New chemical compound can accelerate stem cell mobilization

The finding has led to the development of a new chemical compound that can accelerate this process (called stem cell mobilization) in mice - which could eventually lead to more efficient stem cell harvesting for human use.

Specialized immune-system B cells play dual role in triggering both kinds of immunity - innate and acquired

A specialized subpopulation of the antibody-producing B cells of the immune system plays a "double-barreled" role in triggering both kinds of immunity - innate and acquired, Duke University Medical Center immunologists have discovered.

Research sets foundation for new generation of vaccines for HIV, influenza

Scientists have taken a major step toward the goal of altering viruses, bacteria and tumor cells so that they demand attention from immune cells designed to destroy them.

Single protein regulates secretion levels - helps stem cells become secretory cells

Johns Hopkins researchers have discovered that a single protein regulates secretion levels in the fruit fly's salivary gland and its skin-like outer layer.

Molecular link between a viral infection and development of a common and fatal form of liver cancer

Researchers at The University of Texas M. D. Anderson Cancer Center have uncovered a crucial molecular link between a viral infection and development of a common and fatal form of liver cancer. In the process, they have identified a possible way to treat this disease as well as a number of other cancers.

Decreased breast cancer survival associated with high TRAIL-R2 expression

High expression of TRAIL-R2, a cell surface receptor that triggers cell death, has been shown to be associated with a decrease the survival rates of breast cancer patients according to a study published by Yale Cancer Center researchers in Clinical Cancer Research.
