The results showed that compared with that in the control group, the expression of mir-129-5p in the TGF-β-induced fibrosis group was significantly decreased (0.12 ± 0.08, P < 0.01), while the NDK mixture-containing serum increased the expression of mir-129-5p (0.77 ± 0.55, P < 0.01) (Figure 2(c)). Here, TGFB1 is linked to fibrosis.
