Cytosolic protein extracts were isolated from liver tissue and separated in SDS-PAGE as detailed before [34 (link)]. After transferring proteins to a polyvinylidene difluoride membrane (Bio-Rad Laboratories, Hercules, CA, USA), and incubating them with primary antibodies detecting cleaved caspase 3 (Cell Signaling Technology, Massachusetts, USA) or β-actin (Santa Cruz Biotechnology, Dallas, Texas, United States), bands were detected using Super Signal West Dura kit (Thermo Fisher Scientific, Waltham, MA, USA) [34 (link), 36 (link)] and analyzed using the ChemiDoc XRS System with Image Lab software (Bio-Rad Laboratories, Hercules, CA, USA).
