Figure 3. TUSC7 specifically inhibits miR-23b. (A) Putative binding sites of miR-23b within TUSC7 mRNA, and the sequences of wild-type and mutant-type vectors. (B) In peritoneal macrophages co-transfected with wild-type vectors and pagomir-23b, relative luciferase activity was inhibited rather than co-transfected with mutant vectors. Firefly luciferase activity normalized to renilla luciferase. **p < 0.01.
