Figure 2. miR-27-3p impairs fibroblast function in vitro. (A) qRT-PCR was used to detected levels of miR-27-3p expression. (B) CCK8 assays were used to assess the viability of fibroblasts. (C) Fibroblast migration was evaluated using transwell assays. (D) Flow cytometry was used to evaluate apoptosis (Q2+Q3) among fibroblasts: Q1, dead cells; Q2, later apoptosis; Q3, early apoptosis; Q4, living cells. (E, F) pro-apoptotic and anti-apoptotic proteins were assessed with Western blotting and qRT-PCR. (G, H) The ECM-related proteins collagen III, MMP1 and MMP3 were evaluated with Western blotting and qRT-PCR.
