TRPV2 and basal cell carcinoma: In order to confirm the results of the microarray analysis, the expression of several genes included in “WNT/β-Catenin signaling”, “basal cell carcinoma signaling”, “regulation of the Epithelial-Mesenchymal Transition Pathway”, and the relationship between stem cell-related genes and TRPV2 expression were validated in more detail using quantitative RT-PCR.
