How diabetes drugs may work against cancer

How diabetes drugs may work against cancer

For several years, a class of anti-diabetic drugs known as biguanides, has been associated with anti-cancer properties. Continue reading

Major ‘third-hand smoke’ compound causes DNA damage and potentially cancer

Major ‘third-hand smoke’ compound causes DNA damage and potentially cancer

Leftover cigarette smoke that clings to walls and furniture is a smelly nuisance, but now research suggests that it could pose a far more serious threat, especially to young children who put toys and other smoke-affected items into their mouths. Scientists reported today that one compound from this “third-hand smoke,” which forms when second-hand smoke reacts with indoor air, damages DNA and sticks to it in a way that could potentially cause cancer Continue reading

Small-RNA pathway defends genome against enemy within

Small-RNA pathway defends genome against enemy within

Reproductive cells, such as an egg and sperm, join to form stem cells that can mature into any tissue type. But how do reproductive cells arise? We humans are born with all of the reproductive cells that we will ever produce Continue reading

Roomy cages built from DNA could one day deliver drugs, devices

Roomy cages built from DNA could one day deliver drugs, devices

Move over, nanotechnologists, and make room for the biggest of the small. Scientists at the Harvard’s Wyss Institute have built a set of self-assembling DNA cages one-tenth as wide as a bacterium Continue reading

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.
