A study on mice by researchers has uncovered a mutation in the brain-derived neurotrophic factor (BDNF) gene responsible for overeating. The gene mutation prevents leptin and insulin hormones, released after eating, from passing through the brain and causing satiety. Mice with the BDNF mutation suffered from severe obesity. Despite its obvious link to obesity, how BDNF controls body weight has yet to be determined.
We would like to acknowledge that The Varsity's office is built on the traditional territory of several First Nations, including the Huron-Wendat, the Petun First Nations, the Seneca, and most recently, the Mississaugas of the Credit. Journalists have historically harmed Indigenous communities by overlooking their stories, contributing to stereotypes, and telling their stories without their input. Therefore, we make this acknowledgement as a starting point for our responsibility to tell those stories more accurately, critically, and in accordance with the wishes of Indigenous peoples.
