MicroRNAs are involved in the development and progression of gastric cancer

Area of Science:

• Molecular Biology
• Oncology
• Genetics

Background:

• MicroRNAs (miRNAs) are crucial RNA molecules with diverse biological functions.
• Altered miRNA expression is implicated in gastric cancer (GC) pathogenesis, acting as both tumor suppressors and oncogenes.
• The precise roles of miRNAs in GC progression remain incompletely understood.

Purpose of the Study:

• To review recent advances in miRNA research concerning gastric tumor cell proliferation, apoptosis, and cell cycle regulation.
• To provide insights into the mechanistic roles of miRNAs in GC development and progression.
• To summarize current knowledge on miRNA impact on epithelial-mesenchymal transition, tumor microenvironment, and chemoresistance in GC.

Main Methods:

• Literature review of recent studies on microRNAs in gastric cancer.
• Analysis of miRNA regulatory mechanisms in GC cell proliferation, apoptosis, and cell cycle.
• Synthesis of findings on miRNA involvement in epithelial-mesenchymal transition, tumor microenvironment, and chemoresistance.

Main Results:

• MiRNAs significantly influence gastric tumor cell proliferation, apoptosis, and cell cycle.
• MiRNAs play critical roles in epithelial-mesenchymal transition and the tumor microenvironment.
• MiRNA alterations are associated with chemoresistance in gastric cancer cells.

Conclusions:

• MicroRNAs are integral to understanding gastric cancer etiology and progression.
• Elucidating miRNA molecular mechanisms can facilitate the development of novel therapeutic strategies for GC.
• Further research into miRNA functions holds promise for improving GC treatment outcomes.
