NAC inhibited NLRP3 inflammasomes in the cardiocytes aging model. H9c2 cells were pre-treated with or without NAC (1 mM), a commonly used ROS scavenger, for 1 hour and then incubated with or without 10 g/L D-gal for 24 hours. (A) Representative confocal fluorescent images showed that NAC pre-treatment decreased the colocalization of NLRP3 (red) and caspase-1 (green) proteins in the cardiocytes aging model induced by D-gal. (B) Representative immunoblots of the NLRP3 and ASC proteins and the corresponding quantification were shown. (C) IL-1β, IL-18 and LDH release levels in cell culture were detected. NLRP3, Nod-like receptor family pyrin domain containing 3; ASC, apoptosis-associated speck-like protein.
