A subset of ER stress-induced JAK1-dependent signaling is insensitive to kinase inhibition of JAK1. (A) Astrocytes were pretreated with JAK1/2 kinase inhibitor AZD1480 (1 μM) for 1 h before 0.5 h treatment with oncostatin M (OSM). Protein lysates were collected and analyzed by immunoblot. (B) Astrocytes were pretreated with AZD1480 for 1 h and then treated with thaps for 4 h. Gene expression was analyzed by RT-qPCR. Data are represented as means ± standard deviation. N = 3. ∗p < 0.05.
