Over-expression of CUB domain containing protein 1 in human endometrial cancer.
Gynecologic cancers including cancers of the endometrium are a clinical problem (1-4). We mined published microarray data (5, 6) to discover genes associated with endometrial cancers by comparing transcriptomes of the normal endometrium and endometrial tumors from humans. We identified CUB domain containing protein 1, encoded by CDCP1, as among the most differentially expressed genes, transcriptome-wide, in cancers of the endometrium. CDCP1 was expressed at significantly higher levels in endometrial tumor tissues as compared to the endometrium. Importantly, in human endometrial cancer, primary tumor expression of CDCP1 was correlated with overall survival in endometrial cancer patients with Grade 2 tumors. CDCP1 may be a molecule of interest in understanding the etiology or progression of human endometrial cancer.
