Study Title | Metabolomic and lipidomic profiles in response to exogenous insulin and GLP-1 infusions during prolonged fasting |
Study Type | Timecourse |
Study Summary | Seventeen northern elephant seal pups constituting four different cohorts at Año Nuevo State Reserve were studied at two post-weaning periods: early (1-2 wk post weaning; n=5) and late (6-7 weeks post weaning; n=12). Study #1: Prior to each infusion protocol, plasma U/kg). Following the infusion, blood samples were collected at 10,To determine the effects of prolonged fasting on peripheral insulin activity and function, samples were collected. Ten fasting seal pups (n=5 early, n=5 late) were infused (i.v.) with a mass-specific dose of insulin (0.065 U/kg). Following the infusion, blood samples were collected at 10, 30, 60, 90, and 120 minutes. Study #2: Seven, late-fasted seal pups were administered either a low (LDG; 10 pmol/kg; n=3) or high (HDG; 100 pmol/kg; n=4) dose of GLP-1 immediately following a glucose bolus (0.5 g/kg) (i.v.) infused within 2 mins. the infusions, blood samples were collected at 10, 30, 60, 90, 120, and 150 minutes. |
