ACVR1 and head and neck squamous cell carcinoma: Although most of the genes are indeed downregulated in HNSCC cells expressing miR-30a-3p or miR-30e-3p, as confirmed by RT-qPCR, some of them are overexpressed in either cell lines or in response to either miRNA (such as GADD45, ACVR1, LTBP2, BNC1, SPTBN1, and DPYSL3 in SCC9, Figure 3b).
