Because UCA1 is highly expressed in bladder transitional cell carcinoma, it was suggested as a biomarker for diagnosing bladder cancer.[36] Zheng et al[37] detected UCA1 expression in 112 pairs of tumorous and adjacent normal tissues of patients with gastric cancer and found that high UCA1 expression was correlated with poor differentiation, tumor size, invasion depth, TNM stage, and poor overall survival. Here, UCA1 is linked to neoplasm.
