Abstract:
Objective To establish a small cell lung cancer (SCLC) multidrug resistance (MDR) cell line SH77/CDDP and analyze its biological properties. Methods The SCLC MDR cell line SH77/CDDP was established by increasing gradually the dose of cisplatin, the first line chemotherapeutic drug for lung cancer. The chemosensitivities of SH77/CDDP and its parental cell line to 7 chemotherapeutic drugs were tested. Changes in cellular morphology and ultrastructure were observed. The cell growth curve and cell cycle were also determined. Results SCLC MDR cell line SH77/CDDP having different drug resistance to the 7 chemotherapeutic drugs was established successfully. Compared with that of its parental cell, the size of MDR cell was a bit bigger. The ratio of nucleus to cell plasma decreased and mitochondria, Golgi bodies, rough endoplasmic reticulums and free ribosomes increased. The finger like apophysis was obvious. The rate of cell proliferation of SH77/CDDP was similar to that of SH77, but the number of cells in S phase increased( P
