WebMar 7, 2011 · In addition, the AMPK activator metformin reversed the EB-induced decreases in food intake and weight gain and restored the ability of WIN 55,212-2 to reduce mEPSC frequency. These data reveal that estrogens physiologically antagonize cannabinoid-induced changes in appetite and POMC neuronal activity by activating PI3K and inhibiting AMPK. WebMay 7, 2016 · A Gene Mutation That May Affect Appetite. The gene that is linked to a Labrador Retriever's weight gain and obesity is known as the POMC or pro-opiomelanocortin gene. (There may be other genes that can also cause obesity in the breed.) The mutation consists of the deletion of a section of DNA from the gene.
