In the myocardial tissue of DCM mice and high-glucose (HG)-treated NMCMs, TRA was found to correct the aberrant expression of key proteins involved in pyroptosis, including cleaved-caspase1, NLRP3, phospho-NF-κB cyclooxygenase-2, interleukin Cleaved-IL-1β, Cleaved-IL-18, and gasdermin D. Furthermore, TRA effectively curtailed the excessive production of ROS and augmented the mitochondrial membrane potential in NMCMs under the HG environment. The gene discussed is IL18; the disease is familial dilated cardiomyopathy.
