Abstract:
:Acquired resistance of afatinib is a significant challenge for non-small cell lung cancer (NSCLC) therapy and the mechanisms remain unclear. Aberrant activation of epidermal growth factor receptor (EGFR)-dependent downstream pathways, especially phosphatidylinositol-3-kinases/protein kinase B (PI3K/Akt) signaling pathway has been reported to be involved in the occurrence of afatinib resistance. Developing effective anti-cancer agents to overcome afatinib resistance by targetting PI3K/Akt signaling pathway will be a potential strategy for NSCLC treatment. Shikonin is a naphthoquinone compound isolated from the roots of Lithospermum erythrorhizon In the present study, the anti-cancer activity of Shikonin was evaluated on afatinib-resistant NSCLC in vitro and in vivo The data showed that Shikonin inhibited the proliferation and induced apoptosis of afatinib-resistant NSCLC cell line by activating apoptosis signaling pathway and negatively regulating PI3K/Akt signaling pathway. These results revealed that Shikonin was a potential apoptosis inducer in afatinib-resistant NSCLC and a promising candidate for treating patients clinically.
