Insights Into Translatomics in the Nervous System

Area of Science:

• Neuroscience
• Molecular Biology
• Genetics

Background:

• Neurological disorders often stem from errors in gene translation, disrupting neuronal and glial function.
• Current transcriptomic and proteomic analyses have limitations in directly correlating mRNA and protein levels for translational studies.

Purpose of the Study:

• To highlight the importance of translatomics in understanding gene translation in neurological diseases.
• To review key translatomics methods for profiling ribosome-associated mRNAs.

Main Methods:

• Focus on three primary translatomics techniques for analyzing ribosome-nascent chain complex-mRNA (RNC-mRNA).
• These methods capture and sequence mRNAs actively being translated by ribosomes.

Main Results:

• Translatomics effectively identifies translational changes, including ribosome stalling and transcript isoforms, within the nervous system.
• Applications of these methods in studying glioma, neuropathic pain, depression, fragile X syndrome, and neurodegenerative disorders are discussed.

Conclusions:

• Advances in translatomics are essential for overcoming limitations in current proteomic and transcriptomic approaches.
• This review enhances understanding of how aberrant gene translation contributes to the development of neurological diseases.
