Zeng et al. observed high expression levels of spliced variants TRPC1β, TRPC3a, TRPC4β, TRPC4γ, and TRPC6 (with exon 3 and 4 deletions), as well as a novel TRPC1 isoform with exon 9 deletion (TRPC1(E9del)) in human ovarian adenocarcinoma and ovarian adenocarcinoma-derived cell line SKOV3 [41]. Here, TRPC1 is linked to ovarian adenocarcinoma.
