Objective To explore the expression of long noncoding RNA ( lncRNA) RN7SK and its screening value in clinical diagno-sis of gastric cancer. Methods The expression of lncRNA RN7SK in gastric cancer cells and paired gastric cancer tissues were meas-ured by qRT-PCR. The screening efficacy was detected by the receiver operating characteristic ( ROC) curve. Results The expression levels of lncRNA RN7SK in gastric cancer lines SGC-7901(3.91±0.53),MGC-803(3.44±0.29),HGC-27(4.04±0.87)and BGC-823 (4.30±1.13) were markedly higher than that in human gastric mucosal epithelial cell line GES-1, and the difference had statistical sig-nificance(1.02±0.27, t=12.33, 7.48, 7.20 and 4.90, P<0.05). The expression of RN7SK was up-regulated in 85.5% (47/55) of gastric cancer tissues while down-regulated in the the other 8 tissues ( 14. 5%) . The area under ROC curve ( AUCROC ) of lncRNA RN7SK expression in gastric cancer patients was 0.827 and the 95% confidence interval (CI) was from 0.746 to 0.907. When the cut-off value was 0.618, the sensitivity and specificity were 0.836 and 0.782 respectively. Conclusion The level of lncRNA RN7SK should be overexpressed in gastric cancer tissues so that it may have high screening efficacy and could be used as a potential molecular marker for the diagnosis of gastric cancer.

Exosomes are nanometer-sized vesicles that contain various types of biologically active components, including proteins, nucleic acids, carbohydrates, and lipids, which vary with the type and physiological state of the cell. In recent years, several studies have showed that exosomes can provide new non-invasive diagnostic and prognostic biomarkers in patients affected by cancers, including bladder cancer (BC), and the lipid bilayer membrane structure makes exosomes as promising delivery vehicles for therapeutic applications. Exosomes have the characteristics of high abundance, high stability, tissue specificity, and wide distribution in body fluids, and are secreted as various types by cells in different states, thereby possessing great potential as biomarkers for BC. Herein, we briefly summarize the functions and roles of exosomes in the occurrence and development of BC and the current progress of research on exosomes in BC, while focusing on potential clinical applications of the diagnosis, treatment, and prognosis of BC.
