a Western blot analyses for pAKT (S473, serine 473; T308, threonine 308), AKT, pERK, and ERK in control (shCTL) and stable PIERCE1 KD (shP#1 and shP#3) A549 cell lines. HSP90 was used as a loading control. Western blot analyses for pAKT (S473) and AKT in control and stable PIERCE1 KD A549 cell lines 36 hours after transient transfection of PIERCE1-GFP (b) and in time dependent TGFβ-treatment conditions (c). GFP was used to detect overexpressed PIERCE1. ACTIN was used as a loading control. Western blot analyses for pAKT (S473), AKT under TGFβ and TNFα treatment conditions during transient transfection of PIERCE1 (d) or doxycycline-induced PIERCE1 overexpression condition (e) in A549 cells. Doxycycline (1 μg/mL) was administered for 48 hours. ACTIN was used as a loading control. Overexpression of PIERCE1 was verified using GFP or PIERCE1 antibodies.
