The Epigenteics Of Obesity

The Epigenteics Of Obesity

By Hamilton Erridge

Ever since the human genome project was finished researchers have been searching for the "genes of obesity" without much success. Recently a new field of genetics has emerged termed "epigenetics" which studies how certain genes are turned on and how strongly they are turned on, has provided some new clues as to how people may be more prone to becoming obese.

The researchers looked at the blood of 74 adults and scanned over 4.5 million genes for an epigenetic "tag" called a methyl group. These methyl groups are genetic "switches" that turn genes on or off. The researches found that of the 74 adults, those that were obese had a very specific pattern of methyl groups on certain genes compared to those that were not obese.

If it turns out that this specific pattern of methyl group tagging holds up, it may be a signature of obesity, that could allow doctors to identify people at risk of developing obesity and assisting them early on as children. Future research is looking to confirm the initial study results.
