Signaling pathways required for expansion of insulin-producing beta cells

IDDM, which used to be referred to as Type 1 diabetes, results from selective destruction of insulin-producing pancreatic islet beta cells by the body's immune system.

Plasminogen activator inhibitor type 2 may play role in infection and dry eye

Plasminogen Activator Inhibitor Type 2 (PAI-2), a protein found in various cell types including the skin, has been discovered in the tissue covering the eye and may have future clinical implications in various pathologies of the ocular surface such as eye infection or dry eye.

Association between Pak1 expression and subcellular localization and tamoxifen resistance in breast cancer patients

A protein that activates estrogen receptors in breast cancer may play a role in resistance to therapeutic effects of anti-estrogen tamoxifen treatment, according to a study in the Journal of the National Cancer Institute.

Gene family of potential tumor inhibitors identified

Proteins from a newly discovered family of genes, LRIG, function as a retardant for a protein that is important to tumor cells. It is probably this mechanism that lends the gene family its inhibiting effect on cancer tumors.

Oxygen free radicals associated with Parkinson's Disease

Research by neuroscientists at the University of Virginia Health System shows that oxygen free radicals are damaging proteins in mitochondria, the tiny cellular 'batteries' of brain cells.

Exercise shown to protect against skin and bowel cancer

Two studies have shown that exercise can protect against skin and bowel cancer, and they have identified new mechanisms that could be responsible for this effect.

Taking astrocytes seriously

By blowing gentle puffs of air onto a mouse's whiskers and watching how its brain reacts, scientists are discovering that a long-overlooked signaling system in the brain is crucial to our everyday activity.

Exercise a possible factor in protection against skin and bowel cancer

According to two new studies proper exercise may provide some protection from skin and bowel cancers.

New compound shows unique potency against cancer cell proliferation

By determining how a class of compounds blocks signaling in cells, University of California, San Francisco (UCSF) scientists have identified what is perhaps the most potent drug candidate yet against a highly lethal kind of brain tumor.

Exercise protects against skin cancer

While doctors and scientists have long agreed that physical activity has health benefits, Rutgers cancer researcher Allan Conney and his New Jersey colleagues have found that exercise can even protect against skin cancer.

Researchers discover naturally occurring growth factor that stimulates regeneration of injured nerve fibers in the central nervous system

Researchers at Children's Hospital Boston have discovered a naturally occurring growth factor that stimulates regeneration of injured nerve fibers (axons) in the central nervous system.

SOX2 neural stem cell gene important in eye development

Scientists at the University of North Carolina at Chapel Hill have demonstrated that normal development of the eye requires the right amount of a neural stem cell gene be expressed at the right time and place.

Signaling pathways in immune cells may lead to novel HIV treatment

New research on signaling pathways in immune cells bolsters evidence of connections between the central nervous system and the immune system.

A dual PI3 kinase/mTOR inhibitor reveals emergent efficacy in glioma

Scientists have identified a new molecule that inhibits proliferation of a broad range of lethal malignant glioma cells in vitro and in vivo.

Low affinity analogs of thyrotropin-releasing hormone are super-agonists

Chemical knockoffs resembling a key thyroid-related hormone are, in certain cases, more effective than the real thing at activating the target receptor.

First animal model that mimics human head and neck cancer

An Oregon Health & Science University Cancer Institute research laboratory has developed a novel mouse model designed specifically to study the often devastating head and neck squamous cell cancers.

Renal cell carcinoma in the pediatric population

While the incidence of renal cell carcinoma (RCC) is rising, it remains a relatively uncommon malignancy in the pediatric population, where it represents only 2-6% of solid renal malignancies.

Study holds promise for malarial susceptibility test

Cell and animal studies conducted jointly by scientists at Johns Hopkins, Yale and other institutions have uncovered at least one important contributor to the severe anemia that kills almost half of the 2 million people worldwide who die each year of malaria.
