This study aimed to investigate the antiproliferative, apoptotic, and antioxidant effects of AP on human lung adenocarcinoma cells (A549) and to investigate the effects on Bax, Bcl-2, NF-κB, and caspase-3 signaling pathways that may play a role in the pathogenesis of lung cancer. Here, CASP3 is linked to lung carcinoma.
