Clinical significance of high expression with UTX in renal cell carcinoma

To investigate the expression and significance of ubiquitously transcribed TPR gene on the X chromosome (UTX) in renal cell carcinoma (RCC) tissues, then to explore the relationship between UTX expression and renal cancer pathologic characteristics.In the study, 45 patients with dignosed renal cell carcinoma clinical samples were collected in Peking University Shenzhen Hospital. Total RNA and protein were extracted from the cancer tissues and adjacent normal tissues. UTX expression of cancer tissues and adjacent normal tissues was detected on both mRNA and protein levels using real time-PCR and IHC, respectively. And the relationship between UTX expression and the 45 patients' clinical characteristics was analyzed.The mRNA level of UTX in cancer tissues(C) was 4.4 folds, higher than that of the adjacent normal tissues(N) [ 0.883 2±0.703 8 vs. 0.199 7±0.140 0, P<0.05]. The protein expression of UTX in cancer tissues was up-regulated, and the protein score of cancer tissues was 4 folds, change compared with adjacent normal tissues[12±4 vs. 3±3, P<0.05].The expression of UTX was associated with pathological grade(P=0.004)but without gender, age, tumor size and TNM stage.UTX is up-regulated in RCC tissues and the expression of UTX is associated with pathological grade, illustrating that UTX may play an important role in renal cancer progression.PubMed06926-304
