Elevated expression levels of TRPC1, TRPC6, TRPM7, TRPM8, and TRPV6 are detected in human breast ductal adenocarcinoma (hBDA) cells (19), whereby the expressions of TRPC1, TRPM7, and TRPM8 were most closely correlated with proliferative deregulation and tumor growth, and TRPV6 was more strongly correlated in invasive breast cancers. The gene discussed is TRPC1; the disease is invasive breast carcinoma.
