Over-expression of KIAA0101 (PCLAF) 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 KIAA0101, also known as the PCNA clamp-associated factor (PCLAF) as among the most differentially expressed genes, transcriptome-wide, in cancers of the endometrium. KIAA0101 was expressed at significantly higher levels in endometrial tumor tissues as compared to the endometrium. Importantly, primary tumor expression of KIAA0101 was correlated with recurrence-free survival in patients with endometrial cancer. KIAA0101 may be a molecule of interest in understanding the etiology or progression of human endometrial cancer.
