Long non-coding RNAs and their role in muscle regeneration

Area of Science:

• Genomics
• Molecular Biology
• Biochemistry

Background:

• Most of the mammalian genome is transcribed into non-protein coding RNAs, categorized by size.
• Long noncoding RNAs (lncRNAs) are a large, versatile class of molecules with emerging roles as gene expression regulators.
• lncRNAs are modulated during myogenic differentiation and are crucial for skeletal muscle development, homeostasis, and neuromuscular disease pathogenesis.

Purpose of the Study:

• To summarize current knowledge on lncRNAs in skeletal muscle.
• To discuss specific lncRNAs (including lncRNAs and circRNAs) that regulate muscle stem cell biology.
• To review lncRNAs implicated in common neuromuscular diseases.

Main Methods:

• Literature review and synthesis of existing research on lncRNAs in skeletal muscle.
• Focus on lncRNAs involved in myogenic differentiation and muscle stem cell regulation.
• Analysis of lncRNAs associated with neuromuscular disease mechanisms.

Main Results:

• lncRNAs play significant roles in regulating gene expression at multiple levels within skeletal muscle.
• Specific lncRNAs and circular RNAs (circRNAs) are identified as critical regulators of muscle stem cell function.
• Several lncRNAs are implicated in the pathophysiology of prevalent neuromuscular disorders.

Conclusions:

• lncRNAs are vital regulators in skeletal muscle, impacting development, differentiation, and disease.
• Understanding lncRNA functions offers potential therapeutic avenues for neuromuscular conditions.
• Further research into lncRNAs and circRNAs is essential for advancing skeletal muscle biology and treating related diseases.
