From: Overexpression of Insig-1 protects β cell against glucolipotoxicity via SREBP-1c
Overexpression of Insig-1 suppressed SREBP-1c transcription and affected mRNA expression of insulin secretion genes. Two groups of cells were exposed to 11.2 mM or 25.0 mM glucose for 0, 24 and 72 h, mRNA level of insulin secretion genes and FAS was detected by real-time PCR. A-G represented SREBP-1c, IRS-2, PDX-1, GLUT-2, insulin, UCP-2 and FAS mRNA fold change in INS-1-Insig-1 cells compared to INS-1 cells. * P < 0.05, ** P < 0.01 VS control INS-1 cells at the same time point.
