Project Title:Glutathione-deficiency promotes basal hyperinsulinemia in the insulin secreting cell line INS-1 (832/13)
Project Summary:This study sought to determine the impact of Glutathione (GSH) synthesis on β-cell function. Glutamate-cysteine ligase catalytic subunit (Gclc) is essential for GSH synthesis. To induce GSH deficiency, GCLC was inhibited in INS-1 (832/13) cells using buthionine sulfoximine (BSO). The 24-hour treatment of INS-1 cells with BSO (250 µM) reduced GSH levels to 33% of untreated, however, glucose-stimulated insulin secretion was unchanged. The 24-hour treatment of INS-1 cells with BME-free medium containing BSO further reduced GSH levels to 9% of untreated and elicited significantly higher basal insulin secretion. We sought to determine if higher basal insulin secretion was related to metabolic alteration therefore, we performed a metabolomics screen. This data is presented here. Out of 53 identified metabolites, we found 6 with significantly lower abundance in -BME+BSO as compared to -BME. Those include, adenosine monophosphate, deoxycytidine monophosphate, glucose 1-phosphate, ADP-glucose, thymidine monophostphase, and deoxycytidine diphosphate.
