Over-expression of annexin A1 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 annexin A1, encoded by ANXA1, as among the most differentially expressed genes, transcriptome-wide, in cancers of the endometrium. ANXA1 was expressed at significantly higher levels in endometrial tumor tissues as compared to the endometrium. Importantly, in human endometrial cancer, primary tumor expression of ANXA1 was correlated with recurrence-free survival in white patients with low mutational burden. ANXA1 may be a molecule of interest in understanding the etiology or progression of human endometrial cancer.
