With this perspective, we report that mice lacking the G protein gamma(3)-subunit (Gng3(-/-) mice) show resistance to high-fat diet-induced weight gain over the course of a 12-wk study. Compared with Gng3(+/+) controls, female Gng3(-/-) mice exhibit a 40% reduction in weight gain and a 53% decrease in fat pad mass, whereas male Gng3(-/-) mice display an 18% reduction in weight gain and no significant decrease in fat pad mass. The basis for the lowered weight gain is related to reduced food consumption for female and male Gng3(-/-) mice of 13% and 14%, respectively. Female Gng3(-/-) mice also show a lesser preference for high-fat chow than their female Gng3(+/+) littermates, suggesting an attenuated effect on a reward pathway associated with overconsumption of fat. One possible candidate is the micro-opioid receptor (Oprm1) signaling cascade. Supporting a defect in this signaling pathway, Gng3(-/-) mice show marked reductions in both acute and chronic morphine responsiveness, as well as increases in endogenous opioid mRNA levels in reward-related regions of the brain. Taken together, these data suggest that the decreased weight gain of Gng3(-/-) mice may be related to a reduced rewarding effect of the high-fat diet resulting from a defect in Oprm1 signaling and loss of the G protein gamma(3)-subunit."xsd:string |
