CDK10, CDK11, FOXO1, and FOXO3 Gene Expression in Alzheimer's Disease Encephalic Samples

Area of Science:

• Neuroscience
• Genetics
• Molecular Biology

Background:

• Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by neuroinflammation and the accumulation of β-amyloid and tau pathology.
• The precise genetic factors contributing to AD pathogenesis remain incompletely understood.
• Investigating gene expression in brain tissues offers insights into AD development.

Purpose of the Study:

• To compare the gene expression of CDK10, CDK11, FOXO1, and FOXO3 in the auditory cortex and cerebellum of Alzheimer's disease patients and elderly controls.
• To identify potential genetic markers associated with AD development.

Main Methods:

• Gene expression analysis using quantitative real-time polymerase chain reaction (RT-qPCR).
• Samples were obtained from 82 individuals: 45 with AD and 37 age-matched controls.
• Statistical analyses included comparative analysis and Spearman correlation tests.

Main Results:

• A statistically significant increase in CDK10 and CDK11 gene expression was observed in the AD group compared to controls, particularly in the cerebellum.
• Positive correlations in gene expression for CDK10 and CDK11 were found in both AD and control groups within the auditory cortex and cerebellum.
• No significant differences or correlations were found for FOXO1 and FOXO3 gene expression between the groups.

Conclusions:

• CDK10 and CDK11 exhibit elevated expression in Alzheimer's disease patients.
• The positive correlation of CDK10 and CDK11 gene expression suggests their involvement in the pathogenesis of Alzheimer's disease.
• FOXO1 and FOXO3 do not appear to play a significant role in the studied AD cohort based on gene expression levels.
