TRPM3 and thyroid cancer: Treatment with 5′-aza-2-deoxycytidine (5′AZA), a demethylating agent, for 24 h led to a significant increase of miR-204-5p and its host gene (TRPM3) transcripts in TPC-1 and BCPAP cells, suggesting that DNA methylation mediates miR-204-5p silencing in thyroid cancer cell lines (Figure 7b,c).
