Genetic patch ‘stops deafness’
4 February 2013 Last updated at 21:33 ET By James Gallagher Health and science reporter, BBC News A tiny “genetic patch” can be used to prevent a form of deafness which runs in families, according to animal tests. Patients with Usher syndrome have defective sections of their genetic code which cause problems with hearing, sight and balance.
New stroke gene discovery could lead to tailored treatments
Jan. 31, 2013 A study led by King’s College London has identified a new genetic variant associated with stroke
Gene found that turns up effect of chemotherapy
Jan. 29, 2013 Chemotherapy is one of the most common treatments for cancer patients
One-step test for mitochondrial diseases
Jan. 28, 2013 More powerful gene-sequencing tools have increasingly been uncovering disease secrets in DNA within the cell nucleus. Now a research team is expanding those rapid next-generation sequencing tests to analyze a separate source of DNA — within the genes inside mitochondria, cellular power plants that, when abnormal, contribute to complex, multisystem diseases
New mutations discovered driving malignant melanoma
Jan. 24, 2013 Two new mutations that collectively occur in 71 percent of malignant melanoma tumors have been discovered in what scientists call the “dark matter” of the cancer genome, where cancer-related mutations haven’t been previously found.
Linchpin of skin response to UVA light discovered
Jan. 21, 2013 Researchers have strengthened their understanding of how skin cells called melanocytes sense ultraviolet light and act to protect themselves with melanin. In a new study, they report experiments showing that an ion channel well-known elsewhere in the body for its chemical sensitivity, plays a central role in this process
Enzyme helps cancer cells avoid genetic instability
Jan. 21, 2013 Cancer cells are resourceful survivors with plenty of tricks for staying alive. Researchers have uncovered one of these stratagems, showing how cells lacking the tumor suppressor BRCA1 can resume one form of DNA repair, sparing themselves from stagnation or death.
DNA chip to diagnose attention deficit hyperactivity disorder?
Jan. 21, 2013 Attention Deficit Hyperactivity Disorder (ADHD) is the most common childhood neuropsychiatric disorder. Yet there is currently no tool that will confirm the diagnosis of ADHD
Tumors evolve rapidly in a childhood cancer, leaving fewer obvious treatment targets
Jan. 20, 2013 An extensive genomic study of the childhood cancer neuroblastoma reinforces the challenges in treating the most aggressive forms of this disease. Contrary to expectations, the scientists found relatively few recurrent gene mutations — mutations that would suggest new targets for neuroblastoma treatment.
Epigenetics explains rheumatism? Genes and their regulatory ‘tags’ conspire to promote rheumatoid arthritis
Jan. 20, 2013 In one of the first genome-wide studies to hunt for both genes and their regulatory “tags” in patients suffering from a common disease, researchers have found a clear role for the tags in mediating genetic risk for rheumatoid arthritis (RA), an immune disorder that afflicts an estimated 1.5 million American adults.
