Gene variants protect against relapse after treatment for hepatitis C

Gene variants protect against relapse after treatment for hepatitis C

More than 100 million humans around the world are infected with hepatitis C virus. The infection gives rise to chronic liver inflammation, which may result in reduced liver function, liver cirrhosis and liver cancer Continue reading

‘Master regulator’ of obesity? Distant IRX3 gene appears to interact with obesity-related FTO gene mutations

‘Master regulator’ of obesity? Distant IRX3 gene appears to interact with obesity-related FTO gene mutations

Mutations within the gene FTO have been implicated as the strongest genetic determinant of obesity risk in humans, but the mechanism behind this link remained unknown. Now, an international team of scientists has discovered that the obesity-associated elements within FTO interact with IRX3, a distant gene on the genome that appears to be the functional obesity gene.

Cellular alchemy: How to make insulin-producing cells from gut cells

Cellular alchemy: How to make insulin-producing cells from gut cells

Destruction of insulin-producing beta cells in the pancreas is at the heart of type 1 and type 2 diabetes. “We are looking for ways to make new beta cells for these patients to one day replace daily insulin injections,” says Ben Stanger, MD, PhD, assistant professor of Medicine in the Division of Gastroenterology, Perelman School of Medicine at the University of Pennsylvania.

Genetic patch ‘stops deafness’

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. Continue reading
