Abstract

Gastric cancer is a common, worldwide malignancy and has a poor prognosis due to late diagnosis. Long non-coding RNAs (lncRNAs) are a significant subtype of RNA molecules with a length longer than 200 nucleotides (nt) that rarely encode proteins. In recent decades, deregulation of lncRNAs has been shown to be involved in tumorigenesis and tumor progression in various human carcinomas, including gastric cancer. Accumulating evidence has shown that some lncRNAs may function as diagnostic biomarkers or therapeutic targets for gastric cancer. Thus, exploring the specific functions of lncRNAs will help both gain a better understanding of the pathogenesis and develop novel treatments for gastric cancer. In this review, we highlight the expression and functional roles of lncRNAs in gastric cancer, and analyze the potential applications of lncRNAs as diagnostic markers and therapeutic targets.

Core tip: Gastric cancer is a common, worldwide malignancy that has a poor prognosis. The promising regulatory potential of long non-coding RNAs (lncRNAs) in tumorigenesis and cancer development, including gastric cancer, has been widely demonstrated. Thus, exploring the function of lncRNAs can help to both gain a better understanding of the pathogenesis and develop novel treatments for gastric cancer. In this review, we aim to elucidate the expression patterns and functional roles of lncRNAs in gastric cancer, and analyze the latent applications of lncRNAs as diagnostic markers and therapeutic targets.
