Abstract
Transcriptome study in neurodegenerative disease has advanced considerably in the past 5 years. Increasing scientific rigour and improved analytical tools have led to more-reproducible data. Many transcriptome analysis platforms assay the expression of the entire genome, enabling a complete biological context to be captured. Gene expression profiling (GEP) is, therefore, uniquely placed to discover pathways of disease pathogenesis, potential therapeutic targets, and biomarkers. This Review summarizes microarray human GEP studies in the common neurodegenerative diseases amyotrophic lateral sclerosis (ALS), Parkinson disease (PD) and Alzheimer disease (AD). Several interesting reports have compared pathological gene expression in different patient groups, disease stages and anatomical areas. In all three diseases, GEP has revealed dysregulation of genes related to neuroinflammation. In ALS and PD, gene expression related to RNA splicing and protein turnover is disrupted, and several studies in ALS support involvement of the cytoskeleton. GEP studies have implicated the ubiquitin–proteasome system in PD pathogenesis, and have provided evidence of mitochondrial dysfunction in PD and AD. Lastly, in AD, a possible role for dysregulation of intracellular signalling pathways, including calcium signalling, has been highlighted. This Review also provides a discussion of methodological considerations in microarray sample preparation and data analysis.
Key Points
-
Gene expression profiling (GEP) has advanced considerably over the past 5 years, and has provided important insight into mechanisms underlying neurodegenerative disease
-
In amyotrophic lateral sclerosis, GEP studies have consistently implicated certain biological structures and pathways, including the cytoskeleton, inflammation, protein turnover and RNA splicing
-
GEP studies in Parkinson disease have highlighted dysfunction of the ubiquitin–proteasome system, RNA splicing, mitochondrial function and inflammation
-
In Alzheimer disease, affected pathways identified by GEP analysis include neuroinflammation, mitochondrial function and calcium signalling
-
GEP studies have investigated selective vulnerability to neurodegeneration between patients and in different anatomical areas of the CNS, in order to characterize disease mechanisms, identify therapeutic targets and potentially inform development of individualized treatments
-
Technical aspects of GEP, including sample preparation, data analysis and validation, require careful consideration to optimize assays and yield reliable results
