This observation suggests that the p53 tumour suppressor gene is involved in the evolution of epithelial ovarian cancer (EOC) and may have prognostic significance.
Growth of epithelial ovarian cancer is influenced by several factors including transforming growth factor-alpha and transforming growth factor-beta, macrophage colony stimulating factor, tumor necrosis factor-alpha, interleukin-1 and interleukin-6, c-erb B-2 (HER-2/neu), and mutant p53.
P-Glycoprotein expression was evaluated in 98 frozen tumor specimens from 57 patients with epithelial ovarian cancer by the indirect immunoperoxidase technique with monoclonal antibodies C219 and JSB-1 used for detection.
P-glycoprotein was positive on luminal surfaces of lining cells of ovarian cancer and on those of inclusion cysts from which epithelial ovarian cancer is considered to develop.
A protein receptor tyrosine kinase (RTK 6) has been isolated from a complementary DNA library of SKOV-3, an epithelial ovarian cancer cell line, using a polymerase chain reaction (PCR)-mediated approach.
The authors analyzed the expression of HER-2/neu on frozen tumor specimens from 40 patients with early epithelial ovarian cancer using the indirect immunoperoxidase technique with monoclonal antibodies that detect epitopes on the extracellular domain of the HER-2/neu protein.
Glucocorticoid regulation of HER-2/neu expression was investigated using the SK-OV-3 human epithelial ovarian cancer cell line in which the HER-2/neu gene is amplified five- to eightfold.
In a study of nine families with "site-specific" ovarian cancer (criterion: three or more cases of epithelial ovarian cancer and no cases of breast cancer diagnosed at age < 50 years) we have obtained evidence of linkage to the breast-ovarian cancer susceptibility gene, BRCA1 on 17q12-21.
Immunohistochemical detection of mutant p53 protein in epithelial ovarian cancer using polyclonal antibody CMI: correlation with histopathology and clinical features.
CA 125, the most widely used marker, is nonspecific, being elevated in about 80% of cases of ovarian epithelial cancer but also elevated in a number of benign conditions, which reduces its potential effectiveness as a screening tool.
Tumor necrosis factor-alpha induced up-regulation of p53 tumor suppressor gene expression in epithelial ovarian cancer cell lines, together with the induction of cell death by apoptosis.

Recombinant interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha) can induce endogenous TNF-alpha mRNA expression and stimulate proliferation of epithelial ovarian cancer cells.
