Genetic cause discovered for systemic lupus erythematosus

Mutations in a gene researchers call TREX1 is one cause for systemic lupus erythematosus (SLE), a severe and incurable autoimmune disease.

Brain controls the way fat is stored and metabolized

A system in the brain already known to regulate food intake also serves as a direct "remote control" for the way fat is stored and metabolized in the body, say University of Cincinnati (UC) researchers.

Study looks at mitochondrial variation in sperm traits and sperm competitive ability

University of Nevada, Reno researchers Jeanne and David Zeh of the Department of Biology have received a five-year, $650,000 grant from the National Science Foundation to investigate the effects of natural mitochondrial variation on sperm traits and sperm competitive ability.

Discovery of cause of Job's syndrome

The rare immunodeficiency disorder known as Job's syndrome is caused by a specific genetic mutation that both overstimulates and understimulates the human immune system, leading to harmful bacterial and fungal infections and the physical features characteristic of the syndrome, according to two independent groups of scientists, one from the National Institutes of Health (NIH) and the other from the Tokyo Medical and Dental University.

Study examines implications of genetic screening for disease that can be less serious, treatable

Some couples in Israel whose fetus screened positive for Gaucher disease, which can range from being mild and treatable to being a severe disease, decided to have the pregnancy terminated, raising questions concerning the appropriateness of certain types of genetic screenings, according to a study in the September 19 issue of JAMA.

New cell death pathway involved in sperm development

Heavy and bulky sperm would not be good swimmers. To trim down, sperm rely on cell death proteins called caspases, which facilitate the removal of unwanted cellular material and radically remodel these cells into their sleek, light shape.

New understanding of gene mutation responsible for fragile X syndrome

Scientists have discovered how the gene mutation responsible for fragile X syndrome - the most common inherited form of mental retardation - alters the way brain cells communicate.

New guidelines to diagnose Alzheimer's disease

Physicians may be able to detect and treat Alzheimer's Disease (AD) in its earliest stages, when patients are experiencing only mild degrees of cognitive impairment, thanks to new diagnostic criteria proposed by an international group of researchers.

Mutations in the glucocerebrosidase gene are risk factors for Parkinson's disease

People with a certain gene mutation are more likely to get Parkinson's disease before the age of 50 compared to those without the gene abnormality, according to a study published in the September 18, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

Androstenone determines whether male body odor smells pleasant

New research from Rockefeller University, performed in collaboration with scientists at Duke University in North Carolina, reveals for the first time that this extreme variability in peopl's perception of androstenone is due in large part to genetic variations in a single odorant receptor called OR7D4.
