RNA modification-mediated multidimensional crosstalk: a novel perspective on gene expression regulation.

Area of Science:

• Molecular Biology
• Epigenetics
• Biotechnology

Background:

• RNA modifications are crucial for regulating RNA metabolism.
• These modifications interact with DNA, protein, and other RNA modifications, forming complex regulatory networks.
• Understanding these crosstalks is essential for deciphering gene expression control.

Purpose of the Study:

• To propose a framework for understanding RNA modification crosstalk.
• To delineate the mechanisms and functions of reciprocal modification axes.
• To explore translational applications of RNA modification crosstalk.

Main Methods:

• Review of existing literature on RNA modifications and their interactions.
• Development of a two-dimensional framework ('cis/trans' and 'direct/indirect').
• Analysis of four reciprocal modification axes: RNA-DNA, RNA-histone, RNA-non-histone, and RNA-RNA.

Main Results:

• A novel framework is proposed to categorize RNA modification crosstalk mechanisms.
• Four key reciprocal modification axes are identified and analyzed.
• RNA modification crosstalk offers significant potential for translational applications.

Conclusions:

• RNA modification crosstalk is a fundamental regulatory mechanism.
• The proposed framework aids in understanding complex gene expression control.
• Further research into RNA modification crosstalk can accelerate advancements in disease therapy, tissue engineering, and plant biotechnology.
