First Embryos in UK Screened for Disease

...from an embryo, rather than focusing on a specific mutation in one gene, making it quicker to spot diseases. In addition researchers also look at genetic clues for the disease in the mother and father. The presence of a particular number suggests the embryo is affected. Both Catherine and her husband Jim, ...

Chronic Kidney Disease Related To Mutant Gene

...embryo, so defects were present at birth. A milder mutation seemed to interfere with repair mechanisms in the glomerulus, so defects didn't show up until later in life.' U-M scientists used DNA microarrays to analyze blood samples from 26 families around the world who had children diagnosed with steroid-re...

Strong Evidence Suggests Incidence Of Mating Of Ancestors With Neanderthals

...ch seems to have undergone a conspicuous change or mutation about 37,000 years ago. this gene's modified versions or allele seems to impart an advantage which ensures a fitness in those who possess this allele which is seen in 70% of the population today. This suggests some evidence of mixing of genes 37,000 ...

Colon cancer Linked to low-folate diet

... The researchers also tested mice with a genetic mutation that impairs the body's ability to metabolize folic acid. It was found that rodents with the mutation and also fed a low-folate diet had more than double the incidence of intestinal tumours. "It's sor...

Bird flu outbreak prevented by Tamiflu

...entral China) to Turkey, where the virus underwent mutation and got assorted with the Vietnamese strain. This re-assorted virus strain was brought to India by migratory birds. This kind of re-assorted virus attack has not been reported for the past 4 years in any country. "The influenza virus mutates qui...

Gene Involved In Common Birth Defect Also Regulates Skin Biology

...rray. The Manchester team investigated a different mutation in the mouse IRF6 gene and observed similar results to the UI study. This second study will also be published in Nature Genetics. 'The support from the CARC was critical to the completion of these two studies because several different disciplines w...

Risk of Autism doubled with Single Gene Mutation

...tibility to autism is increased with a single gene mutation according to research conducted by, a Vanderbilt-led research team//. This discovery has far-reaching implications because this gene, a variant form of a gene called MET, is not just specifically a brain gene but rather a gene which has its effect o...

Understanding Sleeping Sickness

A New Way to Treat Colon Cancer?

...ere able to rescue zebrafish from the effects of a mutation in the adenomatous polyposis coli (APC) gene. In humans, mutations in this gene long have been known to initiate a series of events that cause colon polyps, which eventually become cancerous. APC mutations play a role in 85 percent of colon cancers...

Stringent Bird Flu Monitoring Accelerated In China

...sts have already warned of a grim possibility of a mutation in the genetic make-up of the virus that causes bird flu that could enable ‘man-to-man’ infections also Dearth of funds, being understaffed and lack of suitable vaccines are some of the other hurdles that China faces today to tackle this killer disea...

Novel Techniques to Tackle Colon Cancer

Mutations in this gen...

Closing In On the Breast Cancer Gene

...ccording to the researchers the occurrence of this mutation in the population is rare, and new research has lent an insight into just how many of these types of genetic mutations can actually occur in the disease. Researchers said in a statement "In breast cancer families without BRCA 1 or BRCA 2 gene mut...

Highly Potent TB Strain Plays Favorites Targeting Specific Ethnic Groups

...lleagues at Imperial College, London, discovered a mutation in the CH strain, capable of debilitating the immune system of the infected people. Professor Barer, whose study was published in the Proceedings of the National Academy of Sciences, said "If it is adapting to different groups, we may need new approa...
