NIH researchers link single gene variation to obesity
Variation in the BDNF gene may affect brain’s regulation of appetite, study suggests
A single variation in the gene for brain-derived neurotropic factor (BDNF) may influence obesity in children and adults, according to a new study funded by the National Institutes of Health. The study suggests that a less common version of the BDNF gene may predispose people to obesity by producing lower levels of BDNF protein, a regulator of appetite, in the brain. The authors propose that boosting BDNF protein levels may offer a therapeutic strategy for people with the genetic variation, which tends to occur more frequently in African Americans and Hispanics, than in non-Hispanic Caucasians. The study is published in the journal Cell Reports.
