Mutations are changes in the molecular 'letters' that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Mitochondria are well known as the powerhouses of the cell because of their energy generating capabilities. These little organelles are very special, because they also carry their own tiny little ...

Meet the luckiest people on Earth — individuals carrying a rare genetic mutation that prevents wrinkles from forming even as they age well into their 80s. These genetic lottery winners have provided ...

Some genetic mutations that are expected to completely stop a gene from working surprisingly cause only mild or even no symptoms. Researchers in previous studies have discovered one reason why: cells ...

Bowel cancer cells have the ability to regulate their growth using a genetic on-off switch to maximize their chances of survival, a phenomenon that's been observed for the first time by researchers at ...

Australian researchers have discovered that a single mutation in the DNA sequence for a methylation enzyme dysregulates key tumor-suppressing pathways, opening up new avenues for blood cancer ...

An affordable new BRCA gene test has hit the market, but who should take it? — -- A new genetic testing kit that hits the market today is the most affordable, and arguably one of the simplest, ...

Modern HIV medicine is based on a common genetic mutation. Now, researchers have traced where and when the mutation arose—and how it protected our ancestors from ancient diseases. What do a ...
