TRPM3 and head and neck squamous cell carcinoma: We first examined miR-204 host gene TRPM3 expression by quantitative PCR (qPCR) and observed near complete TRPM3 suppression in four micro-dissected HNSCC tumors (Figure 1B) and in a panel of 10 low passage HNSCC cell lines generated from tumors of diverse head and neck locations (Figure 1C and Table 5 in Text S2) [26].
