The effects of metformin and ATO on the mTORC1 and AMPK/MAPK pathways in ICC in vitro. a and c The effect of metformin and ATO single or combination treatment on the active status of mTORC1, AMPK/MAPK, and ERK3 pathways of ICC cells was determined by western blotting. b and d The data were quantified and are represented as the means ± SD from three independent experiments. (Combination vs metformin * P < 0.05, combination vs ATO # P < 0.05)
