Transcriptional profiling of clonal INS-1 832/13 beta-cells

ABSTRACT: This experiment aimed to measure gene expression in glucose-responsive beta-cells. RNA was extracted using RNeasy Mini kit. Quantity and quality of extracted RNA were assessed by the NanoDrop spectrophotometer ND-1000 and Experion RNA StdSens Analysis Kit, respectively. Background correction, normalization, and probe summarization were performed by the Robust Multichip Average method. More details can be found in J Biol Chem (doi: 10.1074/jbc.M112.422527).

Lipotoxicity is a presumed pathogenetic process whereby elevated circulating and stored lipids in type 2 diabetes cause pancreatic β-cell failure. To resolve the underlying molecular mechanisms, we exposed clonal INS-1 832/13 β-cells to palmitate for 48 h. We observed elevated basal insulin secretion but impaired glucose-stimulated insulin secretion in palmitate-exposed cells. Glucose utilization was unchanged, palmitate oxidation was increased, and oxygen consumption was impaired. Halting expos  ...[more]
