PIO upregulated hepatic SIRT1/Notch1 signaling in TAM- received rats. PIO upregulated SIRT1mRNA (A) and decreased Notch1 mRNA (B) along with reduced HES1 level (C) in TAM-received rats. Data are mean ± SEM, n = 6. *P < 0.05, **P < 0.01, and ***P < 0.001. D PIO and SIRT1 interacted with one another multiple times, according to a molecular docking study. In addition to a hydrogen bond, these interactions also involve the residues Ile227 and Lys235. TAM tamoxifen, PIO pioglitazone, SIRT1 Sirtuin 1, HES1 hairy and enhancer of split1
