M2‐polarized tumor‐associated macrophages promote epithelial‐mesenchymal transition via activation of the AKT3/PRAS40 signaling pathway in intrahepatic cholangiocarcinoma

Tumor‐associated macrophages (TAMs) have been considered as a major component of the tumor microenvironment. However, the crosstalk between M2‐polarized tumor‐associated macrophages (M2‐TAMs) and intrahepatic cholangiocarcinoma (ICC) remains undetermined. In the present study, we aimed to clarify the role of M2‐TAMs in ICC and the underlying mechanism. The in vitro assay demonstrated M2‐TAMs promoted epithelial‐mesenchymal transition (EMT) of...
