Noncoding RNAs in gastric cancer: Research progress and prospects

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Noncoding RNAs (ncRNAs) play vital roles in cellular processes like proliferation and apoptosis.
• Dysregulation of ncRNAs is implicated in the initiation, progression, invasion, and metastasis of various cancers, including gastric cancer (GC).
• Emerging ncRNAs, such as PIWI-interacting RNAs (piRNAs) and circular RNAs (circRNAs), are increasingly recognized for their roles in cancer.

Purpose of the Study:

• To review recent advances in understanding the role of ncRNAs in gastric cancer pathobiology.
• To highlight the significance of competing endogenous RNA (ceRNA) networks in GC tumorigenesis.
• To discuss the potential applications of ncRNAs in GC diagnosis and therapy.

Main Methods:

• Literature review of recent studies on ncRNAs in gastric cancer.
• Analysis of the components and interactions within ceRNA networks relevant to GC.
• Synthesis of current knowledge on ncRNA dysregulation in GC progression.

Main Results:

• ncRNAs are significantly involved in multiple stages of GC development.
• ceRNA networks, comprising mRNAs, microRNAs, lncRNAs, and circRNAs, are critical in GC tumorigenesis.
• Specific ncRNAs show potential as biomarkers and therapeutic targets for GC.

Conclusions:

• ncRNAs are key players in gastric cancer pathobiology.
• Understanding ncRNA-mediated ceRNA networks offers insights into GC mechanisms.
• Targeting ncRNAs presents promising avenues for future GC treatment strategies.
