MAPK3 and colonic neoplasm: Contrasting to other studies, Peng et al. [177], reported that over-expression of FXR suppressed the proliferation of H508, SNU-C4, and HT-29 colon cancer cells, whereas the inhibition of FXR by GS resulted in increased proliferation of the colon cancer cells through the upregulation of Src, EGFR, and ERK-1/2.
