Noncoding RNAs in protein clearance pathways: implications in neurodegenerative diseases

Area of Science:

• Genomics
• Molecular Biology
• Neuroscience

Background:

• The noncoding genome, previously overlooked, plays vital roles in cellular functions and disease.
• Noncoding RNAs (ncRNAs), including microRNAs (miRNAs) and long ncRNAs (lncRNAs), are implicated in various physiological and pathological states.
• Neurodegenerative diseases are characterized by the accumulation of toxic, misfolded proteins.

Purpose of the Study:

• To review the significance of ncRNAs in the protein quality control (PQC) system.
• To explore the involvement of ncRNAs in neurodegenerative diseases.
• To identify ncRNAs as potential therapeutic targets for neurodegeneration.

Main Methods:

• Literature review focusing on ncRNAs and protein quality control.
• Analysis of studies investigating ncRNA roles in neurodegenerative disease models.
• Synthesis of current understanding of ncRNA-mediated PQC pathways.

Main Results:

• ncRNAs are integral components of cellular machinery, including the PQC system.
• Dysregulation of ncRNAs is linked to impaired PQC and the pathogenesis of neurodegenerative diseases.
• Upregulation of protein clearance pathways, potentially modulated by ncRNAs, shows promise in combating neurodegeneration.

Conclusions:

• ncRNAs are critical regulators of protein homeostasis and are implicated in neurodegenerative disorders.
• Targeting ncRNAs offers a promising avenue for developing novel therapeutic strategies against neurodegenerative diseases.
• Further research into ncRNA function in PQC is essential for understanding and treating these debilitating conditions.
