Figure Lengend Snippet: Cytokines Activated Their Downstream Pathways in HK-2 Cells. The phosphorylation of ERK, JNK, p38, and NF-κB in HK-2 cells treated with TNF-α (A) or IL-1β (B) was analyzed over a time course ranging from 15 min to 4 h. The phosphorylation of Smad1/5/9 and Smad2/3 in HK-2 cells treated with TGF-β1 (C) or BMP-2 (D) was analyzed over a time course ranging from 15 min to 4 h. GAPDH was served as the loading control.
