Abstract
Obesity is the result of lifestyle and genetic predisposition. Tens of genes have been found to be associated with obesity. Among those, FTO showed the highest effect on body weight, but the function of the gene product was unknown at the time of discovering this association. As a consequence, several hundreds of studies have now been performed in just the last 6 years to unravel the biological role of FTO as an obesity gene. Although FTO is very likely to act as a RNA demethylase, the process by which FTO influences body weight is still unknown. In this review we have collected and evaluated most of the recent results which contribute to the relatively small but nevertheless important progress in FTO research with respect to obesity.
