Tumor necrosis factor (TNF) α-induced protein kinase C (PKC) ζ signaling cascade depends on the interaction between p62 and PKCζ. A, Human umbilical vein endothelial cell (HUVEC) was transfected with either pcDNA3.1 or Phox/Bem1p (PB1)-GFP and stimulated with TNFα (10 ng/mL) for indicated times. Phosphorylation of JNK at Thr183/Tyr185 was analyzed by immunoblotting. B, Quantification of JNK phosphorylation that was normalized to the expression of total JNK. *P<0.01 compared with the respective time control. C, HUVEC was transfected with either pcDNA3.1 or PB1-GFP and stimulated with TNFα (10 ng/mL)+cyclohexamide (CHX) (10 μg/mL) for 6 hours. The cleavage of caspase 3 was analyzed by immunoblotting. D, Quantification of cleaved form of caspase 3 that was normalized to the expression of actin. *P<0.01.
