A Pilot Proteomic Analysis of Huntington's Disease by Functional Capacity

Area of Science:

• Neuroscience
• Molecular Biology
• Biochemistry

Background:

• Huntington's Disease (HD) involves complex molecular changes including genetic, epigenetic, and proteomic alterations.
• The proteome and metabolome offer insights into cellular function, reflecting both disease pathology and compensatory mechanisms.

Purpose of the Study:

• To explore the relationship between cerebrospinal fluid (CSF) proteomic profiles and functional severity in Huntington's Disease.
• To identify potential protein biomarkers that correlate with HD progression and phenotype.

Main Methods:

• Cerebrospinal fluid (CSF) proteomics analysis was performed on eight Huntington's Disease participants.
• Proteins were assessed for correlation with functional severity (TFC score range 3-13).
• Statistical analysis identified 47 proteins with significant correlations (r-value >= 0.7, p-value < 0.05).

Main Results:

• Exploratory analysis revealed correlations between Huntington's Disease progression and key biological processes.
• Significant correlations were observed with inflammation, extracellular matrix (ECM) homeostasis, and NAD+ metabolism.
• Specific protein targets associated with disease phenotype and progression were identified.

Conclusions:

• Validated protein targets correlating with Huntington's Disease phenotype or progression could serve as valuable biomarkers.
• These biomarkers may enhance clinical trial enrichment strategies.
• Identified targets may also function as markers for therapeutic response in Huntington's Disease.
