Abstract

Cis-diamminedichloroplatinum (II) (cisplatin, CDDP) is a highly effective chemotherapeutic agent against cervical cancer, but drug resistance is a major obstacle in its clinical application. The mechanism of drug resistance in human cervical cancer is not well understood. Here, we established an in vitro endocervical, cisplatin-resistant cell system that mimics the development of cisplatin resistance in the human cervix. Human papillomavirus (HPV) type 16-immortalized human endocervical cells (HEN-16-2) were treated with cisplatin, and the cisplatin-selected cells (HEN-16-2/CDDP) were resistant to cisplatin, paclitaxel, actinomycin D, doxorubicin, etoposide, and 5-fluorouracil, thus demonstrating a multidrug resistance (MDR) phenotype. Furthermore, compared with a similar passage of drug-sensitive HEN-16-2 cells, HEN-16-2/CDDP cells exhibited the general growth characteristics of cancer cell lines: faster growth in medium containing serum and high calcium levels, higher saturation density, anchorage-independent growth, and formation of tumors in nude mice. These results provided the first in vitro evidence that cisplatin selection can transform HPV-immortalized endocervical cells and cause a phenotype of MDR. (C) 2000 Wiley-Liss, Inc.
