Study TitleMetabolomic and lipidomic profiles in response to exogenous insulin and GLP-1 infusions during prolonged fasting
Study TypeTimecourse
Study SummarySeventeen 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.

Project Title:Metabolomic & lipidomic profiles in response to exogenous insulin & GLP-1 infusions during prolonged fasting
Project Type:Timecourse
Project Summary:This application requests funding to access state-of-the-art metabolomics and lipidomic platforms at the NIH West Coast Metabolomics Center to analyze plasma samples from recent insulin and glucagon-like peptide-1 (GLP-1) infusion experiments performed in prolong-fasted elephant seals. This suite of studies was designed to better assess the mechanisms contributing to the onset of an insulin resistantlike condition induced by prolonged food deprivation/starvation in mammals. Because elephant seals have evolved robust physiological mechanisms that have allowed them to naturally tolerate such protracted bouts of fasting, they provide an ideal model to address our central hypothesis that increased lipid utilization late in the fast contributes to insulin resistance in elephant seals. Insulin resistance is a common consequence of fasting in mammals and, while the mechanisms by which it manifests are still unclear, a metabolic shift favoring increased mobilization and utilization of lipids during prolonged food deprivation may be a principal causative factor. Insulin resistance has a negative connotation due to its association with obesity and diabetes among humans, but it has been suggested to be an adaptive response to food deprivation.
