Defective control of pre-messenger RNA splicing in human disease

Area of Science:

• Molecular Biology
• Genetics
• Biochemistry

Background:

• Growing evidence links errors in pre-messenger RNA (pre-mRNA) splicing and alternative splicing to human diseases.
• Mutations in splicing signals and regulatory elements are known causes.
• Recent research also implicates mutations in spliceosome components and splicing regulatory proteins.

Purpose of the Study:

• To review recent advancements in understanding the role of altered splicing function of RNA-binding proteins in disease.
• To highlight the contribution of these splicing defects to specific pathologies.

Main Methods:

• Literature review of recent studies on RNA splicing and disease.
• Focus on the impact of mutated RNA-binding proteins and spliceosome components.
• Analysis of disease mechanisms in myelodysplastic syndromes, cancer, and neuropathologies.

Main Results:

• Accumulating examples demonstrate associations between human diseases and splicing defects.
• Mutations in generic spliceosome components and splicing regulatory proteins disrupt normal splicing.
• Altered splicing function of RNA-binding proteins is a significant contributor to disease pathogenesis.

Conclusions:

• Splicing defects, especially those involving RNA-binding proteins, are critical in the development of myelodysplastic syndromes, cancer, and neuropathologies.
• Further research into these mechanisms is essential for therapeutic development.
• The role of RNA-binding proteins in splicing fidelity and disease warrants continued investigation.
