Since, TRPV6 expression in immunoblotting was rather weak, though detectable, we used tumor sections formed by either PC3Mtrpv6-/- or PC3Mtrpv6-/- +pTRPV6 (a clone 1, where TRPV6 expression was high) cell lines (Fig. 2B and Supplementary Fig. 1B). The gene discussed is TRPV6; the disease is neoplasm.
