Irisin Enhances Doxorubicin-Induced Cell Apoptosis in Pancreatic Cancer by Inhibiting the PI3K/AKT/NF-κB Pathway.

ABSTRACT: BACKGROUND Irisin, a myokine released from skeletal muscle following exercise, has been shown to affect the proliferation of some cancer cells and chemosensitivity of anticancer drugs like doxorubicin (DOX). However, the effects of irisin on chemosensitivity in pancreatic cancer (PC) cells have not been studied. MATERIAL AND METHODS In this study, the effects of irisin co-treatment with DOX or gemcitabine (GEM) on MIA PaCa-2, BxPC-3 PC cells, and H9c2 cardiomyocytes were investigated. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, flow cytometry, and TUNEL (TdT-mediated dUTP nick-end labeling) assays were conducted to evaluate cytotoxicity induced by DOX or GEM. Fluorescence microscopy and flow cytometry experiments were performed to assess the intracellular accu
