MgIG increased p27 expression and β-galactosidase activity in TGF-β-activated LX2 cells. (A) Western blot and densitometric analysis (against GAPDH loading control) of the proteins showed that MgIG induced expression of p27 senescence marker particularly at 24 h treatment. Cells treated with 5 μM camptothecin for 24 and 48 h, respectively, were used as positive controls. (B) TGF-β-activated LX2 cells treated with three different concentrations of MgIG for 48 h exhibited an increase in β-galactosidase activity. Data represents means ± SE, n = 3, one-way ANOVA with Tukey HSD test, p-value < 0.05, ∗significance against non-treated control (NegCtrl) at 48 h.
