Research findings may speed the development of vaccines for Chlamydia and other STDs

Using a novel mouse model that allows scientists to study how the immune system’s fighter cells respond to invaders in the genital tract during the initial stage of infection, researchers have found a way to track immunity against Chlamydia trachomatis.

New insights into how cells repair damaged DNA

Cancer researchers have discovered that a recently identified protein critical for repairing damaged genes uses an unusual mechanism to keep its repairs accurate.

Scientists characterize structure of calbindin-D28K

Scientists at North Carolina State University have effectively lifted the veil from an important protein that is linked to the prevention of neurodegenerative diseases like Alzheimer's and Huntington's.

Heat sensitivity may make testicular cancer cells more susceptible to standard treatments and die off more readily

Experts at Johns Hopkins have linked scientific evidence spanning more than 30 years to suggest an explanation for why testicular cancer patients like seven-time Tour de France winner Lance Armstrong survive far better than patients with other advanced cancers.

Disease-specific gene expression profiles in patients with rheumatoid arthritis

They sleep together, eat together, and most people find it impossible to tell them apart. Identical twins who grow up together share just about everything, including their genes.

NICE backs use of Enbrel and Raptiva to treat severe psoriasis

NICE has today issued guidance for the use of the targeted biological therapies, Enbrel (etanercept) and Raptiva (efalizumab), to treat adult patients with severe plaque psoriasis.

Mechanism linking alcohol to reduced risk of cardiovascular disease may be related to inflammation

Older adults who consume one to seven alcoholic beverages a week may live longer and have a reduced risk for cardiac events than those who do not drink - an association that appears independent of the anti-inflammatory effects of alcohol.

Interaction of proteins in the intestinal system may be allergic indicators

Researchers have identified one of the proteins that may be responsible for causing food allergies, which could lead to the development of more accurate non-invasive tests to identify true food allergies.

Discovery could help identify genes that cause human heart defects

Researchers at UT Southwestern Medical Center have identified a group of fruit fly gene mutations responsible for "broken hearts" in the embryonic stages of development, a discovery that could help identify genes that cause human heart defects.

Low-glycemic index diet promotes weight loss

A diet high in carbohydrates but low on the glycemic index, which measures the impact of carbohydrates on blood sugar levels, may help promote weight loss, decrease body fat and reduce cardiovascular disease risk.

Scientists identifiy the way MDM2 protein can trigger the spread of cancer

The protein, MDM2, normally functions to control the activity of a key cancer preventing protein called p53.

Which came first, nucleic acids or proteins?

Which came first, nucleic acids or proteins? This question is molecular biology's version of the "chicken-or-the-egg" riddle.

Serotonin reciprocally regulates melanocortin neurons to modulate food intake

Some of the most important weight-loss drugs work by enhancing the effect of the brain chemical serotonin.

Gleevec may cause heart problems

Gleevec, the wildly successful poster-child of a new generation of cancer drugs aimed at specific targets in the cancer cell, can be dangerous to the heart.

Research simplifies diagnosis of Charcot-Marie-Tooth disease

Charcot-Marie-Tooth (CMT) disease is the most common hereditary disorder of the peripheral nervous system, leading to a weakening of the muscles in the lower legs, feet and hands as the nerves that run from the spinal cord to the muscles die off.

New molecular target for obesity

Mice bred without the enzyme MKP-1 are resistant to weight gain despite consuming high fat foods and eating more than control mice, according to a research study published online in Cell Metabolism.

Active mind and body slows Alzheimer's progression

Researchers have uncovered the pathways behind the protection offered by environmental stimulation in Alzheimer's disease, further confirming that enhanced mental and physical activity slows neurological decline.
