ABSTRACT
Preliminary studies have shown that systemic beta-human chorionic gonadotrophin (betaHCG) therapy alleviates endometriosis-related chronic pelvic pain. The underlying mechanism, however, is completely unknown. This study has investigated the dose-dependent alterations in the overall gene expression profile of endometriosis-derived stromal cells under increasing concentrations of betaHCG by using the Affymetrix GeneChip U133 Set. It has been previously shown that betaHCG concentrations of 0.1U/ml and higher lead to a significant and dose-dependent increase in the expression of 68 genes. This study reports on a cluster analysis which identified three clusters of genes with a comparable expression pattern in response to increasing concentrations of betaHCG. Most of the up-regulated genes encoded proteins that are involved in cell adhesion, intercellular communication, extracellular matrix remodelling, apoptosis and inflammation. Stromal monocultures from eight patients, treated with and without 50U/ml of betaHCG, were then incubated and real-time polymerase chain reaction for the highly up-regulated genes PAI2, DUSP6, PLAU and MMP1 performed in order to validate the cDNA array findings in patients with endometriosis. Taken together, this study shows that betaHCG induces dose-dependent characteristic response clusters in the gene expression profile of stromal cells obtained from endometriotic lesions which could explain the differential biological responses of betaHCG in endometriosis.
