Additional file 2: Figure S2. of M2-polarized tumor-associated macrophages facilitated migration and epithelial-mesenchymal transition of HCC cells via the TLR4/STAT3 signaling pathway

Levels of the p-ERK, p-Ikkα/β, total STAT3, ERK, Ikkα, and Ikkβ proteins were detected using western blotting. (A) Levels of the p-STAT3 and STAT3 proteins in the control, LPS, and M2-CM + LPS groups. (B) Levels of the p-ERK and ERK proteins in the control, M2-CM + LPS, and M2-CM groups. (C) Levels of the p-Ikkα/β, Ikkα, and Ikkβ proteins in the control, M2-CM + LPS, and M2-CM groups. (TIFF 601 kb
