Background
Alzheimer’s disease (AD) is an all-too-common dementing disease associated with aging, impacting individuals, their families, and society. No specific etiology has been determined despite extensive research over the last century.
Objective
Detoxification is a multifaceted systemic process of variable efficacy that eliminates potentially hazardous exogenous and endogenous substances from the body. Multiple genes responsible for detoxification have been previously identified.
Methods
Utilizing gene set expression analysis, this paper reports two differential gene expression studies comparing AD and non-AD cohorts, first in a Gene Expression Omnibus (GEO) dataset study and second in a tissue RNA-seq study.
Results
We identified several detoxification genes with statistically significant differential expression in AD compared to non-AD samples in both phases of this study.
Conclusions
This set of findings suggests a possible etiologic association of impaired detoxification and AD. Subsequent research to follow up on these findings is needed.
