Abstract:

Cancer, the uncontrolled growth of cells, is a major disease that threatens the worldwide population. Among all cancer types, lung cancer has the highest morbidity rate, with a survival rate of less than 5%. Various studies have focused on discovering a potent anticancer drug that will increase the survival rate of lung cancer patients. Lutein (3,3'-dihydroxy-β, ε-carotene), a carotenoid present in fruits and vegetables, is one such compound that possesses excellent antioxidant properties. The present study was designed to determine the anticancer effect of lutein against A549, a non-small-cell lung cancer cell line. The cytotoxic effect of lutein against lung cancer cells (A549 and HCC827) and normal cells (BEAS-2B) was detected by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The Transwell assay was performed to detect the inhibitory potential of lutein against cell invasion and migration of A549 cells. The inductionof apoptosis by lutein in A549 was analyzed by a double-staining technique using TUNEL (terminal deoxynucleotidyltransferase-mediated dUTP nick end-labeling) and DAPI (4',6-diamidino-2-phenylindole) staining assays to confirm the molecular mechanism exhibited by lutein to induce apoptosis through regulating the phosphoinositide 3-kinase (PI3K)/AKT signaling molecules that are often deregulated in cancerous condition. The results show that lutein inhibits the PI3K/AKT signaling pathway and induces apoptosis in A549, which may therefore be used as a potent natural anticancer drug with no side effects to treat lung cancer.
