Promoting progression and clinicopathological significance of NEAT1 over-expression in bladder cancer

Abstract

Bladder cancer was the most important reason of cancer-related death around the world, and urgently requires new therapeutic methods targeting the malignant tumor. There are many reports that the long noncoding RNAs are participated in different cancers, however, limited data are found between the long noncoding RNAs and bladder cancer. Previous studies have indicated that lncRNAs play vital roles in gene regulatory processes which could influence carcinoma progression.It is well known that lncRNAs can’t code proteins, however, controlling transcription was found in the life process.In the current study,we firstly reported that NEAT1 was consistently up-regulated in bladder cancer tissues compared to the matched tissues and bladder cancer cell lines compared to the normal bladder epithelial cell and the expression level of the NEAT1 in bladder cancer tissues is closely related to its clinical pathologic grade and TNM phase. Cell proliferation inhibition, cell migration suppression and apoptosis induction were detected by knockdown NEAT1. However, it is imperative that this hypothesis is further tested through. In conclusion, NEAT1 may play oncogenic roles and can be used as a therapeutic target for treating human bladder cancer. Our finding provides a new insight into the role of the LncRNA NEAT1 in the bladder cancer.
