Aim: To Characterize a new human lung cancer cell line Am1010, derived from drug-surviving cells (DSCs). Methods: The Am1010 cell line was established after 4 cycles of chemotherapy from an arm muscle metastasic tumor of a patient diagnosed with lung adenocarcinoma. The cell line has been remained in continuous culture for more than one year during this study. Results: The Am1010 cell line demonstrated in vitro multi-drug-resistance to cisplatin, taxol, and gefitinib. The Am1010 cell doubling time without drug treatment was 42.395 h. The IC 50 value of cisplatin was 4.299 μmol/L and >10 μmol/L for the Am1010 and P0318 (a cell line derived from non-DSCs) cells, respectively. The IC 50 value of taxol was 0.067 μmol/L and >1 μmol/L for the Am1010 and P0318 cells, respectively. The IC 50 value of gefitinib was 15.233 μmol/L and >70 μmol/L for Am1010 and P0318 cells, respectively. 11 genes involved in the focal adhesion and cell adhesion pathways were found to be differentially expressed. The cells of Am1010 have a significantly larger chromosome number than most lung cancer cell lines. Conclusion: This novel DSCs derived lung cancer cell line will be a valuable in vitro tool for the investigation of lung cancer drug resistance and metastasis.
