Genome-wide gene expression profiles of ovarian carcinoma: Identification of molecular targets for the treatment of ovarian carcinoma.

Abstract
This study aimed to clarify the molecular mechanisms involved in ovarian carcinogenesis, and to identify candidate molecular targets for its diagnosis and treatment. The genome-wide gene expression profiles of 22 epithelial ovarian carcinomas were analyzed with a microarray representing 38,500 genes, in combination with laser microbeam microdissection. A total of 273 commonly up-regulated transcripts and 387 down-regulated transcripts were identified in the ovarian carcinoma samples. Of the 273 up-regulated transcripts, only 87 (31.9%) were previously reported as up-regulated in microarray studies using bulk cancer tissues and normal ovarian tissues for analysis. CHMP4C (chromatin-modifying protein 4C) was frequently overexpressed in ovarian carcinoma tissue, but not expressed in the normal human tissues used as a control. Our data should contribute to an improved understanding of tumorigenesis in ovarian cancer, and aid in the development of diagnostic tumor markers and molecular-targeting therapy for patients with the disease.
