Curcumin Inhibits Hyperandrogen-Induced IRE1<i>α</i>-XBP1 Pathway Activation by Activating the PI3K/AKT Signaling in Ovarian Granulosa Cells of PCOS Model Rats

<div>Curcumin activates the PI3K/AKT pathway inhibited by DHEA in ovary tissues of PCOS-like rats. (a–d) Sections of ovarian tissues were immunostained for revealing p-PI3K/p-AKT (red) as indicated. The slides were counterstained with DAPI (blue), and the images were captured using an inverted fluorescence microscope. (e, f) The protein expression of p-PI3K, PI3K, AKT, and p-AKT in ovarian tissues was assessed with western blotting. Representative data are displayed, and the relative protein intensity of p-PI3K, PI3K, AKT, and p-AKT was normalized to GAPDH. Three independent experiments were performed with similar results.
