Recombinant human glucagon-like peptide-1 (7-36) enhances insulin release and insulin mRNA expression in INS-1 cells / 中华内分泌代谢杂志

ABSTRACT

In INS-1 cells, the insulin secretion was investigated by radioimmunoassay (RIA) after 4 h incubation in medium containing different concentrations of glucose and recombinant human glucagon-like peptide-1 (rhGLP-1) (7-36). Insulin mRNA level in INS-1 cells was assessed by a semi-quantitative RT-PCR method. rhGLP-1 (7-36) is not only a powerful insulin secretagogue, but also can increase insulin gene expression in INS-1 cells.
