Jiedu Fuzheng decoction improves the proliferation, migration, invasion and EMT of non-small cell lung cancer via the Wnt/β-catenin pathway

Abstract

ObjectivesThis study aimed to investigate the effect of Jiedu Fuzheng decoction (JFD) in non-small cell lung cancer (NSCLC) and its potential therapeutic mechanism.ResultsWe prepared JFD-medicated serum from rats and treated NSCLC cells (A549 and NCI-H1650) with 0.5, 1, and 2 mg/mL JFD-medicated serum. CCK-8 and colony formation assays were used to detect cell proliferation. Transwell assays showed that JFD attenuated cell migration and invasion. JFD and SKL2001 (Wnt/β-catenin activator) were simultaneously used to treat NSCLC cells to verify that JFD regulated the biological behavior of NSCLC via Wnt/β-catenin signaling. It was found that 2 mg/mL JFD had the most significant effect on the activity of NSCLC cells. JFD attenuated proliferation and metastasis but increased the proportion of apoptotic cells. At the same time, JFD downregulated N-cadherin, vimentin and β-catenin protein expression in cancer cells. SKL2001 could restore the improvement of JFD on proliferation, metastasis and apoptosis.ConclusionThis study confirmed that JFD suppressed the occurrence and development of NSCLC by regulating Wnt/β-catenin signaling and provided a novel therapeutic scheme for NSCLC.
