Scientists identify compounds for stem-cell production from adult cells

In the study, the scientists screened known drugs and identified small molecules that could replace conventional reprogramming genes, which can have dangerous side effects.

Gail model no better than coin flip in predicting risk of breast cancer

A statistical model commonly used to predict the risk of breast cancer in women was not accurate when used to evaluate women with atypical hyperplasia, according to a new Mayo Clinic study published in the Oct. 14, 2008, issue of the Journal of Clinical Oncology.

Proteomics provides clues to how tuberculosis thwarts the immune system

A link between the immune system and the self-cleaning system by which biological cells rid themselves of obsolete or toxic parts may one day yield new weapons in the fight against tuberculosis and other deadly infectious diseases.

Wide variability in rheumatoid arthritis drug Methotrexate suggests alternative dosing should be considered

Methotrexate (MTX) is commonly used to treat rheumatoid arthritis (RA) and is suggested as the "anchor" drug in treating the disease.

Lung airway cells activate vitamin D and increase immune response

Vitamin D is essential to good health but needs to be activated to function properly in the human body.

Pycnodysostosis sheds light on enzyme's role in bone metabolism

Pycnodysostosis, a condition from which the painter Henri de Toulouse-Lautrec suffered, is a genetic disease characterized by short stature.

Resveratrol type drug mimics low-cal diet to ward off weight gain

A drug designed to specifically hit a protein linked to the life-extending benefits of a meager diet can essentially trick the body into believing food is scarce even when it isn't, suggests a new report in the November Cell Metabolism.

Apelin hormone shows promise as target for managing insulin resistance and type 2 diabetes

By injecting a hormone produced by fat and other tissues into mice, researchers report in the November Cell Metabolism that they significantly lowered blood sugar levels in normal and obese mice.

New weapon in the fight against obesity and diabetes

A study appearing November 5 in the journal Cell Metabolism demonstrates that a synthetic new chemical entity protects against diet-induced obesity, improves glucose tolerance and insulin sensitivity and enhances exercise endurance by enhancing fat utilization in certain target tissues.

Targeting epigenetic changes helps tackle MLL-AF4 leukemias

A very difficult-to-treat child leukemia may benefit from the discovery of a small but potent epigenetic change that launches the cancer - but could potentially be reversed relatively easily, preventing cancer-promoting genes from being turned on.

Parasites that live inside cells use loophole to thwart immune system

St. Jude Children's Research Hospital scientists have discovered a mechanism by which intracellular pathogens can shut down one of the body's key chemical weapons against them: nitric oxide.

No need for RNA

Not all enzymes that are assumed to require an RNA component in order to function do actually contain RNA. This surprising discovery was made during a project supported by the Austrian Science Fund FWF that focussed on the enzyme RNase P.

Halozyme Therapeutics starts phase 2 trial of insulin with rHuPH20 in type 1 diabetes

Halozyme Therapeutics, Inc. today announced it has started a Phase 2 study of proprietary recombinant human hyaluronidase enzyme (rHuPH20) co-formulations with Humulin R (regular insulin human injection) and with Humalog (insulin lispro) in Type 1 diabetic patients.

Parasites that live inside cells use loophole to thwart immune system

St. Jude Children's Research Hospital scientists have discovered a mechanism by which intracellular pathogens can shut down one of the body's key chemical weapons against them: nitric oxide. The researchers found that the microbes block nitric oxide production by subverting the biochemical machinery used by immune cells called macrophages to produce the chemical.

Persistent bacterial infection exploits killing machinery of immune cells

A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them. This discovery may lead to new treatments and vaccines for tuberculosis (TB) and certain other chronic bacterial and parasitic infections.

Alternative splicing in genes more prevalent than previously believed

Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA.

FDA grants tentative approval for 75th generic anti-retroviral drug

The Food and Drug Administration within the U.S. Department of Health and Human Services (HHS) has reached the milestone of the 75th anti-retroviral generic drug approved or tentatively approved as part of President Bush's Emergency Plan for AIDS Relief (PEPFAR).

Systems biology and glycomics used to study human inflammatory diseases

An innovative systems biology approach to understanding the carbohydrate structures in cells is leading to new ways to understand how inflammatory illnesses and cardiovascular disease develop in humans. The work was described in two recent publications by University at Buffalo chemical engineers.
