New role for miRNA in leukemia discovered

Scientists here have found that mini-molecules called micro-RNA may play a critical role in the progression of chronic myeloid leukemia (CML) from its more treatable chronic phase to a life-threatening phase, called blast crisis.

New understanding of biological effects of alcohol on genes within cells

Alcohol triggers the activation of a variety of genes that can influence the health and activity of brain cells, and new research from Weill Cornell Medical College in New York City sheds light on how that process occurs.

Research findings link weight gain and diabetes to a variety of cancers

During this holiday season with its tempting bounty of edible delights, new research calls attention to the role of the expanding American waistline in health and medicine.

Study shows how mutations in the BRCA1 gene lead to breast cancer

An international team of researchers led by Columbia University Medical Center's Herbert Irving Comprehensive Cancer Center and Sweden's Lund University has, for the first time, revealed how mutations in the BRCA1 gene lead to breast cancer.

Mechanism for regulation of growth and differentiation of adult muscle stem cells is revealed

During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue.

Researchers photograph cystic fibrosis protein interaction

New microscopic pictures show the first-ever physical evidence of interaction between two proteins involved in Cystic Fibrosis (CF) disease.

Antibacterial chemical in bath soaps disrupts hormone activities

A new UC Davis study shows that a common antibacterial chemical added to bath soaps can alter hormonal activity in rats and in human cells in the laboratory - and does so by a previously unreported mechanism.

Chikungunya virus spreads to new vectors

Researchers at the University of Texas Medical Branch have discovered how a key protein switch allows Chikungunya Virus (CHIKV) to spread to new vectors.

Reprogrammed stem cells cure sickle cell anaemia

Scientists in the U.S. have made a breakthrough in the fight against sickle cell anaemia, a blood disease caused by a defect in a single gene.

Smell experience during critical period alters brain

Unlike the circuitry of the visual system, that of the olfactory system was thought to be hardwired: Once the neurons had formed, no amount of sensory input could change their arrangement.

Scientists strike blow in super bugs struggle

Scientists from the University of Manchester have pioneered new ways of tweaking the molecular structure of antibiotics - an innovation that could be crucial in the fight against powerful super bugs.

Discovery of potential "getting drunk" gene

A variant of a gene involved in communication among brain cells has a direct influence on alcohol consumption in mice, according to a new study by scientists supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH), and the U.S. Army.

Missing brain protein may be one of the culprits behind autism and other brain disorders

The protein helps synapses develop. Synapses--through which neurons communicate with one other-underlie our ability to learn and remember. Now Li-Huei Tsai, Picower Professor of Neuroscience at MIT, has uncovered an enzyme that is key to that protein's activity.

Researchers gain new understanding of the causes of dyslexia

Dyslexia marked by poor reading fluency - slow and choppy reading - may be caused by disorganized, meandering tracts of nerve fibers in the brain, according to researchers at Children's Hospital Boston and Beth Israel Deaconess Medical Center (BIDMC).

Genetic markers for mental illness

Researchers have discovered natural genetic differences that might help predict the most effective antipsychotic drugs for particular patients with mental disorders such as schizophrenia, Parkinson's and drug addiction.

Research may lead to more effective sunscreens

Chronic exposure to the sun increases the risk of an individual developing skin cancer because UV light from the sun can cause genetic mutations that enable cells in the skin to grow in an uncontrolled manner.

Lymphatic vessel and lymph node function are restored with growth factor treatment

The frequent spread of certain cancers to lymph nodes often necessitates surgery or radiation therapy that damages the lymphatic system and can cause lymphedema, a condition of localized fluid retention that often increases susceptibility to infections.

Humans not the major target of Shiga toxin

If you've survived Shiga toxin and the after-effects of food poisoning, you may have been the innocent victim of a battle for survival between predator and prey.

Heavy drinking, linked to high number of sex partners in young adults

Psychiatry researchers at Washington University School of Medicine in St. Louis have found that a clinical diagnosis of alcohol dependence in young adults is associated with having a high number of sex partners.

Genetic testing for severe type of migraine may help identify new treatment options

People with a severe type of migraine in which one side of the body becomes weak should consider genetic testing, according to research that has found familial genes for this type of migraine in people who did not have family members experiencing the problem.
