The role of long non-coding RNA UCA1 and MALAT1 in bladder cancer patients

Abstract

BackgroundBladder cancer (BC) is considered the most prevalent tumor of the urinary tract, and incidence rates are rising globally. Long noncoding RNAs (lncRNAs) can serve as biomarkers to help the diagnosis and anticipation of recurrence in cancer patients as they are implicated in carcinogenesis and tumor progression. This study targeted to investigate the expression of lncRNA as urothelial cancer associated 1 (UCA1) as well as metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in the diagnosis of BC. Subjects and methodsThe study included 70 BC patients, 70 benign urinary tract diseases and 70 controls. The UCA1 and MALAT1 expressions were studied utilizing quantitative real-time polymerase chain reaction. ResultsThe UCA1 and MALAT1 expression were significantly increased in patients with BC than patients with chronic cystitis and controls (p < 0.001). The sensitivity and specificity for the diagnosis of BC for UCA1(87.14%, 97.14% respectively) and MALAT1 (92.86%, 90% respectively). Multivariate logistic regression analysis showed that UCA1 and MALAT1 were risk factors for the development of BC where the odds ratio (OR) for UCA1 was 1.262 (CI 1.004–1.587) and MALAT1 was 2.201(CI 1.036–4.676). ConclusionUCA1 and MALAT1 could be potential diagnostic biomarkers with good specificity and sensitivity in bladder cancer.
