The expression or activity of the proteins of interest were detected by WB using protein-specific antibody as described previously [9 (link)]. The rabbit anti-phosphorylation p38 MAPK (Thr180/Tyr182), rabbit anti-phosphorylation p44/42 MAPK (Erk1/2) (Thr202/Tyr204) monoclonal antibody and rabbit anti-phosphorylation STAT3 (Phospho-Tyr705) antibody were provided by Cell signaling technologies (Danvers, MA, USA). Mouse anti-p38, rabbit anti-ERK, anti-STAT3 and mouse anti-GADPH and anti-β-actin antibodies were purchased from Beyotime Institute of biotechnology. Rabbit anti-LANA [9 (link)] and anti-RTA [35 (link)] antibodies were prepared by our laboratory.
