Phlda3 induction under ER stress is downstream of XBP1. 4-Hydroxytamoxifen-treated control (C) and Xbp1flox/flox-Pdx1-CreER (Xbp1f/f) mouse islets (n = 7 experiments) and MIN6 cells transfected with either control siRNA (si-C), siRNA against Xbp1 (siXbp1) or siRNA against Ddit3 (siDdit3) (n = 9–12 experiments) were cultured in the absence (white bars) or presence (black bars) of cytokines (24 h) or palmitate (48 h). Changes in the mRNA levels of Phlda3 in cytokine-treated MIN6 cells (a) and primary islets (b). Changes in the mRNA levels of Phlda3 in palmitate-treated MIN6 cells (c). **p < 0.01, ***p < 0.001, ****p < 0.0001 vs untreated. #p < 0.05, ##p < 0.01 vs control siRNA or control islets.
