TRP channels, including TRPA1, TRPC1, TRPC3, TRPC4, TRPC6, TRPV1-4, TRPM2, TRPM8, PKD2L1, MCOLN1, MCOLN2 had simultaneous high expression levels in tumor cases, while TRPC5, TRPC7, TRPV5, TRPV6, TRPM1, TRPM3, TRPM6, TRPM7, PKD2L2, MCOLN3 had high expression levels in normal cases (Figure 2B). This evidence concerns the gene PKD2L2 and neoplasm.
