ABSTRACT
The current study reveals the anticancer potential of oleanolic acid conjugated chitosan nanocomplex (OAC) in lung cancer (LC). Cell counting kit-8 (CCK-8) and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium (MTT) assay were used to detect cell viability, 5-ethynyl-2'-deoxyuridine (EdU) assay to detect cell proliferation, flow cytometry and TUNEL assay to detect cell apoptosis in A549 (ATCC®CCL-185™) and NCIH460 cells. Transwell evaluated cell migration and invasion ability, transmission electron microscopy and immunofluorescence observed autophagy, and Western blotting detected apoptosis- and autophagy-associated proteins. OAC inhibited LC cell viability, migration, and invasion, and induced apoptosis and autophagy depending on the concentration. The phosphorylation of signal transducers and activators of transcription 3 (STAT3) in cells was weakened after OAC treatment. STAT3 activation restored the inhibition of cell viability and induction of apoptosis by OAC. We conclude that OAC induces apoptosis and inhibits cell viability, which may be related to the STAT inactivation. Therefore, OAC is a promising compound for LC therapy.
