Abstract

Objective: To investigate multi-gene expression in the highly metastasizing human ovarian cancer cell line HO- 8910PM and its mother cell line HO-8910.

Method: The expression of 9 kinds of gene products in HO-8910PM and its mother cell line HO-8910 was detected by S--P immunohistochemical method.

Result: Eight kinds oncogene products showed various degrees of positive expression in both HO-8910PM and HO-8910 cell lines except gene bax. The expression of P53, Cyclin DI, CD44 v6 and EGFR in HO-8910PM was stronger than that in HO-8910. However, the expression of P16, nm23 in HO- 8910PM was weaker than that in HO-8910. There was no significant difference on the expression of C-erbB-2 and bcl-2 between the two cell lines.

Conclusion: Stronger invasive and metastatic patential is found in HO-8910PM than that in HO-8910. Carcinogenesis is a result of multioncogene and multiple step process cooperation.
