Analyzing gene-based apoptotic biomarkers in insomnia using bioinformatics.

Area of Science:

• Neuroscience
• Genetics
• Molecular Biology

Background:

• Insomnia is a prevalent condition with serious health implications.
• Apoptosis-related gene dysregulation is implicated in various neurological disorders.

Purpose of the Study:

• To identify apoptosis-related genes and potential biomarkers for insomnia.
• To explore novel therapeutic targets for insomnia treatment.

Main Methods:

• Analysis of insomnia gene expression profiles from the Gene Expression Omnibus database.
• Differential gene expression analysis, Weighted Gene Co-Expression Network Analysis, and protein-protein interaction network construction.
• Validation of key hub genes (BCL2, SOCS3, IL7R) using Western Blot and qRT-PCR in a modeled insomnia hippocampal neuron system.

Main Results:

• Identified 190 differentially expressed apoptosis-related genes in insomnia.
• BCL2, SOCS3, and IL7R were identified as crucial hub genes.
• Reduced expression of BCL2, SOCS3, and IL7R was observed in modeled insomnia hippocampal neurons, indicating decreased antiapoptotic capacity.

Conclusions:

• Apoptosis-related genes play a significant role in the pathophysiology of insomnia.
• BCL2, SOCS3, and IL7R are potential therapeutic targets for insomnia.
• The study suggests impaired antiapoptotic function in hippocampal neurons contributes to insomnia development.
