Nudt21-mediated alternative polyadenylation of HMGA2 3′-UTR impairs stemness of human tendon stem cell


Figure 2. HMGA2 overexpression protects hTSCs from H2O2-induced cell death, cell senescence and decreased S-phase cell number. hTSCs transfected with lenti-HMGA2 (HMGA2 OE) or the negative control (nc) were subjected to H2O2 treatment at indicated concentrations. Non-transfected cells (mock) were included for comparison. (A) Cell viability was determined by the CCK-8 assay after 24 h of H2O2 treatment. (B) Cell senescence was assessed by β-gal staining after 72 h of H2O2 treatment. (C) Cell cycle analysis was performed by flow cytometry after 24 h of H2O2 treatment. The data shown are from three replicates and are presented as mean ± SD. *p < 0.05, **p < 0.01.
