Matrine inhibits the proliferation and migration of lung cancer cells through regulation of the protein kinase B/glycogen synthase kinase‑3β signaling pathways

2018 
: Lung cancer is the leading cause of cancer-related mortality worldwide. Despite recent advances in treatment, lung cancer remains an incurable disease. Matrine, an active compound isolated from Sophora flavescens, has been demonstrated to inhibit proliferation and induce apoptosis of tumor cells. However, the protective effects and molecular mechanisms of matrine in lung cancer remain elusive. In the present study, the lung cancer cells H1299 and A549 were used to investigate how matrine affects the proliferation, migration and apoptosis of lung cancer cells in vitro. It was demonstrated that matrine is able to significantly suppress the proliferation and colony formation of lung cancer cells in vitro. Using cell apoptosis analysis, wound-healing and Transwell assays, it was demonstrated that matrine induced cellular apoptosis and inhibited the migration of lung cancer cells. Further experiments revealed that matrine significantly suppressed the phosphorylation of protein kinase B (Akt) and glycogen synthase kinase-3β (GSK-3β). The present results suggested that matrine inhibits lung cancer cell proliferation, and induces cell apoptosis by suppressing the Akt/GSK-3β signaling pathway, which demonstrated that matrine may have therapeutic potential for lung cancer.
