Establishment and characterization of a new drug surviving cell line Am1010, derived directly from muscle metastases of a human lung adenocarcinoma patient with multi-drug-resistance to cisplatin, taxol, and gefitinib.

ABSTRACT:

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 metastatic 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 micromol/L and >10 micromol/L for the Am1010 and P0318 (a cell line derived from non-DSCs) cells, respectively. The IC(50) value of taxol was 0.067 micromol/L and >1 micromol/L for the Am1010 and P0318
