Fig. 7: TEFM activated ROS/ERK signaling in HCC cells.

A Flow cytometry for intracellular ROS level in SNU-354 with TEFM knocked-down and HUH-7 cells with TEFM over-expression. B The expression levels of AKT, p-AKT, p65, p-p65, Hif-1α, Erk1/2, p- Erk1/2, JNK, p-JNK, p38, and p-p38 were analyzed by western blot. C The expression levels of p-ERK1/2 were analyzed by western blot. Cells were treated with 90 μM H2O2 or 30 mM NAC for 12 h. D Immunohistochemistry analysis for correlation between TEFM and p-ERK1/2 in 209 tumor tissues from HCC patients (scale bars, 20 μm).
