Results indicate that cfa-let-7a_R+2 mimic significantly reduced the mRNA expression level of beta-1,3-glucuronyltransferase 3 (B3GAT3), ring finger protein 7 (RNF7), transforming growth factor beta receptor 3 (TGFBR3), thrombospondin 1 (THBS1), and translocase of inner mitochondrial membrane 17B (TIMM17B) (Figure 9A). Significant downregulation of RNF7, TGFBR3, THBS1, and TIMM17B was verified by RT-qPCR (Figure 9B).
