H2O2 treatment induced senescent phenotypes and upregulation of total and phosphorylated tau protein in rat astrocytes. (A–C) Statistical analysis of SAHF- (A), SA-β-gal- (B), and 53BP1-foci- (C) positive cells in rat astrocytes treated with different concentrations of H2O2 for 2 days. (D) Protein levels of 53BP1 and p53 (a), p21 and p16 (b), p-tau and tau (c) in rat astrocytes after treated with different concentrations of H2O2. (E–G) quantification of (D). Data indicate the mean values calculated from three independent experiments (±SD).
