Functional expression of TRPV1 was demonstrated in several tumor types including human breast cancer cell lines (MCF-7 and BT-20), human papillary thyroid carcinoma BCPAP cells, prostate cancer (LNCaP and PC-3), urothelial cancer cells, and glioma (51–55). Here, TRPV1 is linked to thyroid gland papillary carcinoma.
