These results suggest that NEAT1 has a potential to function as a clinical biomarker for predicting disease invasiveness and prognosis of patients with OC.
The nuclear paraspeckle assembly transcript 1 (NEAT1) is one of the most highly regulated lncRNAs in recent genomic datasets, however, its biological role and regulatory mechanism in ovarian cancer (OC) development and progression are poorly defined.
The results showed that high expression level of NEAT1 was significantly associated with shorter overall survival in cancer patients (hazard ratio (HR) = 1.53, 95% confidence interval (CI) = 1.36-1.71); in the subgroup analysis, the positive association was also found in patients with hepato-gastroenterol cancers (HR = 1.79, 95% CI = 1.48-2.16), non-small cell lung cancer (HR = 1.35, 95% CI = 1.04-1.76), ovarian cancer (HR = 1.41, 95% CI = 1.11-1.79) and other types of cancers (HR = 1.42, 95% CI = 1.11-1.81).
