Post-translational modifications (PTMs) are key drivers of neurobiological changes in Substance Use Disorder (SUD). Targeting PTMs offers a promising therapeutic strategy for SUD treatment.
Area of Science:
- Neuroscience
- Molecular Biology
- Pharmacology
Background:
- Substance Use Disorder (SUD) involves complex neurobiological changes.
- Post-translational modifications (PTMs) are critical regulators of protein function and stability.
- PTMs influence neuroadaptations in brain regions like the nucleus accumbens, prefrontal cortex, and hippocampus.
Purpose of the Study:
- To review the role of PTMs in SUD.
- To discuss the therapeutic potential of targeting PTMs for SUD treatment.
- To explore PTM influence on synaptic remodeling, gene expression, and behavior.
Main Methods:
- Literature review focusing on PTMs in SUD.
- Analysis of PTMs' impact on protein stability and function.
- Exploration of emerging proteomic techniques.
Main Results:
- PTMs mediate crucial neurobiological changes in SUD.
- PTMs modulate protein stability and function in key brain areas.
- PTMs influence synaptic remodeling, gene expression, and behavior relevant to SUD.
Conclusions:
- PTMs play a central role in the pathophysiology of SUD.
- Targeting PTMs and their enzymes presents a novel therapeutic avenue for SUD.
- Proteomic techniques can identify PTM-related biomarkers for SUD progression.
