Role of FFAR1 in the effect of palmitate on human islet respiration. OCR recordings from human islets exposed to 5.6 mM glucose (white symbols) and 0.5 mM palmitate (black symbols) and sequential addition of ANT203 (panel A). Difference in OCR 20 minutes prior and post addition of ANT203 (panel B). OCR recordings from human islets exposed for 2 hours to 5.6 mM glucose (white symbols), 0.5 mM palmitate (black circles, black bars) or palmitate with ANT825 (black triangles, black bars) and the sequential addition of oligomycin and rotenone/antimycin (panel C). Mitochondrial respiration (panel D) and ATP-coupled respiration (panel E) are shown. Results show mean ± SD in (panels A−C) (N = 10) and mean ± SEM in (panels D and E) (n = 5–7 donor experiments). *P < 0.05 vs. control and #p < 0.05 vs. palmitate.
