Bavachinin exhibits antitumor activity against non‑small cell lung cancer by targeting PPARγ. Mol Med Rep. 2019 Jul 11;: Authors: Ge LN, Yan L, Li C, Cheng K Abstract Bavachinin (BNN), one of the main active ingredients of Psoraleacorylifolia, can activate peroxisome proliferator‑activated receptor γ (PPARγ). PPARγ has become a promising therapeutic target in cancer. The aim of the present study was to explore the antitumor effects of BNN in non‑small cell lung cancer (NSCLC). Cell Counting Kit‑8 and lactate dehydrogenase release assays were performed to measure cell toxicity. Western blotting and immunofluorescence were used to analyze the expression of apoptosis‑related factors and PPARγ. The ability of PPARγ to bind to BNN was evaluated by drug affinity responsive target stability (DARTS) and cellular thermal shift assay (CETSA). A reactive oxygen species (ROS) assay kit was used to detect the ROS level. The results revealed that the survival rates and cell viability of A549 cells were reduced by BNN in a dose‑dependent manner. The present results also demonstrated that BNN dose‑dependently changed the expression of Bcl‑2, Bax, caspases‑3/9 and PPARγ. In addition, through the cytotoxic and anti‑proliferative effects, the apoptosis‑related proteins' inhibitive properties of BNN were completely inhibited by the PPARγ antagonists T0070907 and GW9662. The DARTS and CETSA results confirmed the protein bin...
