Non-coding RNA basis of muscle atrophy

Area of Science:

• Biochemistry
• Molecular Biology
• Genetics

Background:

• Muscle atrophy is a prevalent complication in chronic diseases like heart failure and cancer cachexia, as well as aging and hormonal imbalances.
• The precise molecular mechanisms driving muscle atrophy remain incompletely understood.
• Non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long ncRNAs (lncRNAs), and circular RNAs (circRNAs), are increasingly recognized for their critical roles in cellular regulation.

Purpose of the Study:

• To review the regulatory roles of ncRNAs in muscle atrophy across diverse conditions.
• To highlight ncRNAs as common molecular players in various types of muscle atrophy.
• To summarize current therapeutic approaches and underlying mechanisms for muscle atrophy.

Main Methods:

• Literature review focusing on ncRNA regulation in muscle atrophy.
• Analysis of studies investigating muscle atrophy induced by heart failure, cancer cachexia, aging, COPD, PNI, CKD, unhealthy habits, and hormone use.
• Synthesis of findings on common ncRNA regulators and therapeutic strategies.

Main Results:

• ncRNAs significantly regulate muscle atrophy induced by a wide range of factors, including chronic diseases and external stimuli.
• Specific ncRNAs function as common regulators across multiple etiologies of muscle atrophy, suggesting conserved pathways.
• Current research identifies several therapeutic avenues targeting ncRNAs for muscle atrophy.

Conclusions:

• ncRNAs are crucial in the pathogenesis of muscle atrophy, acting as conserved regulators.
• Further understanding of ncRNA mechanisms in skeletal muscle biology can lead to novel gene therapies.
• Targeting ncRNAs presents a promising strategy for developing effective treatments for muscle wasting conditions.
