Abstract
The natural occurring pristimerin, a quinonemethide triterpenoid, is extracted from a variety of species of the Celastraceae and Hippocrateaceae family. This research investigated the in vitro anti-cancer potential of pristimerin on NSCLC cells NCI-H1299 and elucidated the molecular mechanism. Methods: Cell growth inhibition by pristimerin was assessed using the MTT assay. Apoptosis was detected using the Annexin V/propidium iodide (PI) test. The colony forming assay was used to investigate the anti-proliferative effects of pristimerin. Wound healing assay and the transwell cell migration assay were utilized to determine the inhibitory effects of migration and invasion, respectively. Western blot was used to detect the protein expression, and real-time-quantitative (RT-q) PCR was used to analyze the mRNA expression.
