This review explores the HNF-1beta-dependent pathophysiology of clear cell ovarian cancer, highlighting its association with oxidative stress and identifying a redox-sensitive gene subset linked to detoxification and HNF-1beta targets.

This review examines pathogenetic mechanisms of clear cell epithelial ovarian cancer using genome-wide expression studies, focusing on roles of oxidative stress, detoxification, and the transcription factor HNF-1β. The authors report that in cEOC, 54 genes were highly upregulated and 87.0% were redox-related, with 40.7% of these genes overlapping HNF-1β downstream targets, suggesting an HNF-1β-dependent oxidative stress-induced carcinogenesis pathway involving altered glycogen synthesis, detoxification, and anticancer-agent resistance. A systematic search across PubMed and ScienceDirect up to July 2009 is described, but the work is a synthesis of existing studies rather than a new experimental test of causality. Relevance to endometriosis: the paper highlights that clear cell epithelial ovarian cancer frequently concurrently occurs with endometriosis and contrasts its chemoresistance and prognosis with other ovarian cancers, though its main focus is HNF-1β-linked redox mechanisms rather than endometriosis itself.

Abstract

Epithelial ovarian cancer (EOC) is the most common cause of gynecological cancer-related mortality. Clear cell EOC (cEOC) has a number of clinical features distinguishing it from other EOC because of frequent concurrence of endometriosis and highly chemoresistant nature resulting in a poor prognosis. Recent biochemical studies based on genome-wide expression analysis technology have noted specific expression of a transcription factor, hepatocyte nuclear factor-1beta (HNF-1beta), in cEOC and genetic alteration may be involved in oxidative stress. We describe the HNF-1beta-dependent pathophysiology of cEOC and discuss its role in oxidative stress-induced carcinogenesis. A systematic search was performed in the electronic databases PubMed and ScienceDirect up to July 2009, combining the keywords, genome-wide, microarray, epithelial ovarian cancer, clear cell carcinoma, oxidative stress, and detoxification, with specific expression profiles of genes. The catalog of cEOC-specificity might be a manifestation of six essential alterations in cell physiology: oxidative stress and detoxification, proteases, signal transduction, adhesion, transcription, and metabolism. Among 54 genes highly upregulated in cEOC, 47 genes (87.0%) were associated with the redox-related genes. Several important cEOC-related genes overlap with those known to be regulated by HNF-1beta. Twenty-two (40.7%) of the 54 genes predominantly identified in cEOC were involved in downstream targets of HNF-1beta. The HNF-1beta-dependent pathway might provide new insights into regulation of glycogen synthesis, detoxification and resistance to anticancer agents. This review summarizes recent advances in the understanding of oxidative stress and antioxidant mechanisms in pathogenesis of cEOC. A redox-sensitive subset of cEOC genes linked to oxidative and detoxification pathways was identified and associated with HNF-1beta-specific downstream targets.
