Abstract

OBJECTIVE: The goal of this study was to determine the glucometabolic effects of acute activation of G

METHODS: To address this question, we studied mice that express a G

RESULTS: Acute stimulation of GsD signaling in SKM impaired glucose tolerance in lean and obese mice by decreasing glucose uptake selectively into SKM. However, the acute metabolic effects following agonist activation of β

CONCLUSION: Selective activation of G
