TRPM2 regulates cell cycle through the Ca2+-CaM-CaMKII signaling pathway to promote HCC.

Our results indicate that TRPM2 promotes HCC cell proliferation via activating the Ca2+-CaM-CaMKII signaling pathway to induce the expression of the key G1/S regulatory proteins and accelerate the cell cycle. This study provides compelling evidence of TRPM2 involvement in a previously unrecognized mechanism that drives HCC progression and demonstrates that TRPM2 is a potential target for HCC treatment.
