Establishment and characterization of human ovarian clear cell adenocarcinoma cell line (SMOV-2), and its cytotoxity by anticancer agents

Hum Cell. 1999 Sep;12(3):139-48.

Abstract

A novel cell line derived from a surgically resected ovarian clear cell adenocarcinoma of 46 year-old Japanese woman was established and designated SMOV-2. Cells of this lineage were continuously propagated in vitro over 44 months and were grown in a mono-layered sheet with a doubling time of 48.2 hours. The histopathology of the transplanted tumor in nude mice showed two distinctive cell types, hobnail cells and clear cells, which demonstrated recognizable characteristics of clear cell adenocarcinoma, as compared to resected original tumors. At the molecular level, SMOV-2 cells had the wild type p53 genes that were free from missence mutations. Anticancer agents (cisplatin and paclitaxel) were examined for cytotoxity against these SMOV-2 cells in vitro. These examinations revealed that the chemotherapy-treated cells had decreased proliferation, cell cycle arrests, and induction of apoptosis by the anticancer agents. As can be gleaned from this research, SMOV-2 is a valuable model to study the mechanism of apoptotic responses of solid tumors to future anticancer agents.
