A–C: Quantitative RT-PCR for mRNA levels of β-cell–specific genes Glut2, Ins1/2, Pdx-1, MafA, and Gck in islets from P1, P14, and P56 pancreata (n = 6–11 per group). D and E: Quantitative RT-PCR analysis of UPR genes Atf4, Grp78, Chop, spXbp1, tXbp, and Atf6α and Atf6β in P1 and P14 islets from Pdx-1Cre+/−::Manffl/fl and Manffl/fl mice (n = 6–11 per group).
