Most support Alzheimer's research based on family consent

By the time they have been diagnosed with Alzheimer's disease, many patients' decision-making ability is so impaired that they cannot give informed consent to participate in research studies.

Genetic variation cues social anxiety in monkeys and humans

A genetic variation involving the brain chemical serotonin has been found to shape the social behavior of rhesus macaque monkeys, which could provide researchers with a new model for studying autism, social anxiety and schizophrenia.

Discovery of link between genetic defect on chromosome 15 and epilepsy

In a research published in the advanced online publication of the scientific magazine Nature Genetics, researchers have identified a genetic defect for common epilepsies on chromosome 15.

Discovery of potential biomarker for smoking-related lung diseases

Researchers from Boston University School of Medicine (BUSM) have demonstrated that a recently discovered class of molecule called microRNA (miRNAs), regulate the gene expression changes in airway cells that occur with smoking and lung cancer.

Photoacoustic tomography changes lymph node biopsy, reduces radiaiton exposure

Information obtained from a new application of photoacoustic tomography (PAT) is worth its weight in gold to breast cancer patients.

Research confirms value of risk-reducing salpingo-oophorectomy for women with BRCA mutations

Prophylactic salpingo-oophorectomy-removal of the ovaries and fallopian tubes--reduces the relative risk of breast cancer by approximately 50 percent and the risk of ovarian and fallopian tube cancer by approximately 80 percent in women who carry a mutation in the BRCA1 or BRCA2 gene, researchers report in the January 13 online issue of the Journal of the National Cancer Institute.

Important discovery in human insulin-producing cells

Researchers at the University of Pittsburgh School of Medicine have successfully induced human insulin-producing cells, known as beta cells, to replicate robustly in a living animal, as well as in the lab.

Gene therapy kills brain tumors through selective recruitment of immune cells

Scientists seeking to harness the power of the immune system to eradicate brain tumors face two major hurdles: recruiting key immune cells called dendritic cells into areas of the brain where they are not naturally found and helping them recognize tumor cells as targets for attack.

Proteins called ankyrins required to prevent muscular dystrophy

A protein that was first identified for playing a key role in regulating normal heart rhythms also appears to be significant in helping muscle cells survive the forces of muscle contraction.

Natural 'defence' gene reveals how oestrogen fuels cancer

CANCER RESEARCH UK scientists have shown for the first time how a natural 'defence' gene involved in fighting infections such as common colds, can be triggered by hormones to ignite and drive cancers like breast, ovarian, and possibly prostate cancer. Their findings are published in the Journal of Experimental Medicine.

Wyeth and Santaris Pharma to collaborate on RNA-based medicines

Wyeth Pharmaceuticals, a division of Wyeth, and Santaris Pharma have announced that the companies have entered into a worldwide strategic alliance to discover, develop and commercialize new medicines based on Santaris Pharma's proprietary Locked Nucleic Acid (LNA) drug platform, which allows specific targeting and regulation of microRNAs (miRNAs) and messenger RNAs (mRNAs) as a means to affect gene expression mediated by the targeted RNAs.

Discovery of first gender-linked susceptibility gene for late-onset Alzheimer's disease

In the Jan. 11 online edition of Nature Genetics, they report the results of their two-stage genome-wide association study of patients with Alzheimer's disease. The research showed that women who inherited two copies of a variant in the PCDH11X gene, found on the X chromosome, are at considerably greater risk of developing Alzheimer's disease.
