The expression of TRP ion channel family genes in cancer tissue was higher than those in paracancerous tissue, and the expressions of TRPV6 (in B1 sample), TRPM4 (in B3 sample), TRPC1 (in B3 sample), and PKD1P1 (in B2 sample) were significantly upregulated compared with those in paracancerous tissues. The gene discussed is TRPV6; the disease is cancer.
