Expression of beta-human chorionic gonadotropin in ovarian cancer tissue

The purpose of the present investigation was to determinate expression of human chorionic gonadotropin gene in ovarian cancer tissue. The study included 15 patients with epithelial ovarian carcinoma. The expression of mRNA hCGbeta was determinated by the RT PCR method and the distribution of the hormone in study tissue was analyzed immunohistochemicaly. In all 15 study specimens of the ovarian carcinoma tissue the active hCGbeta gene was found, whereas noncancerous tissue demonstrated lack of the hormone expression. Thus, the study clearly shows that the expression of hCGbeta is the feature of ovarian cancer tissue.
