ER stress-induced activation of IRE1-JNK/XBP-1 is blunted in AIP1-KO
EC. AIP1-WT and AIP1-KO MLEC were treated with Tm (1 μm) for
the indicated times (0, 15, 30, 60,
120, and 240 min). Phosphorylation of IRE1 and JNK and
induction of the spliced XBP-1 (a) and phosphorylation of PERK and
expression of CHOP (b) as well as total AIP1 andβ-tubulin
(c) were determined by Western blot with respective antibodies.
