Synergistic Effect of HAD-B1 and Osimertinib Against Gefitinib Resistant HCC827 Non-Small Cell Lung Cancer Cells.

ABSTRACT: In this study, we investigated the synergistic effect of co-administration of osimertinib and HAD-B1 using gefitinib-resistant non-small cell lung cancer cells, HCC827-GR. HAD-B1 is composed of 4 natural drugs, Panax Notoginseng Radix, Panax ginseng C. A. Meyer, Cordyceps militaris, and Boswellia carterii Birdwood, and has been reported to have therapeutic effects on patients with advanced non-small cell lung cancer in several studies. Resistance to gefitinib in HCC827 cells was acquired through MET activity. Co-treatment with osimertinib and HAD-B1 reduced the cell viability of HCC827-GR cells. In addition, phosphorylation of MET and ERK were effectively suppressed for HCC827-GR cells. And, compared to when osimertinib and HAD-B1 were administered alone, cell proliferation was significant
