RNA-binding proteins and long noncoding RNAs in intestinal epithelial autophagy and barrier function

Area of Science:

• Molecular Biology
• Gastroenterology
• Genetics

Background:

• Intestinal autophagy and barrier function are vital for maintaining epithelial homeostasis.
• RNA-binding proteins (RBPs) and long noncoding RNAs (lncRNAs) regulate gene expression post-transcriptionally.
• These molecules are implicated in physiological processes and human diseases.

Purpose of the Study:

• To review the roles of RBPs and lncRNAs in intestinal epithelial autophagy and barrier function.
• To highlight their involvement in mRNA stability and translation.
• To discuss their interactions and influence on gut defense mechanisms.

Main Methods:

• Literature review focusing on post-transcriptional regulation.
• Analysis of emerging evidence on RBPs and lncRNAs in intestinal health.
• Synthesis of findings on RBP-lncRNA interactions.

Main Results:

• RBPs and lncRNAs significantly regulate intestinal epithelial autophagy and barrier function.
• They control mRNA stability and translation, influencing gene expression.
• Interactions between RBPs and lncRNAs modulate transcript fate and host defense.

Conclusions:

• Understanding RBP and lncRNA roles in post-transcriptional control is crucial for intestinal integrity.
• Targeting RBPs and/or lncRNAs presents a therapeutic strategy for critical illnesses.
• These findings support developing novel treatments to preserve gut epithelial integrity.
