Over-expression of tumor protein D52-like 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 tumor protein D52-like 1, encoded by TPD52L1, as among the most differentially expressed genes, transcriptome-wide, in cancers of the endometrium. TPD52L1 was expressed at significantly higher levels in endometrial tumor tissues as compared to the endometrium. Importantly, in human endometrial cancer, primary tumor expression of TPD52L1 was correlated with overall survival in white patients with low mutational burden. TPD52L1 may be a molecule of interest in understanding the etiology or progression of human endometrial cancer.
