Figure 4. Inhibition of miR-29a on the expression of Collagen I, Collagen III, TGF-β and SMAD2/3.
The expression of Collagen I, Collagen III, TGF-β and p-SMAD2/3 were detected using Western blot and the mimic group was low as compared with the model group (A & B), while the knockdown group was no obvious difference (C & D). Data are indicated as means ± S.E. **P < 0.01. TGF-β: transforming growth factor-β.
