TRPV4 and melanoma: Our results showed that TRPV4 expression in melanoma cells (HaCaT, A375, Sk-mel-24, Malme-3M) was indeed higher when compared to the normal epidermal cell line (HaCaT), as well as gastric-derived cells (GES-1, AGS, MGC-803, BGC-823) and colorectal-derived cells (NCM460, SW480, SW620, HCT116) (Figure 1D).
