Abstract
The common features of all neurodegenerative diseases, including Alzheimer’s disease,
Parkinson’s disease, Amyotrophic Lateral Sclerosis (ALS), and Huntington’s disease,
are the accumulation of aggregated and misfolded proteins and the progressive loss
of neurons, leading to cognitive decline and locomotive dysfunction. Still, they differ in
their ultimate manifestation, the affected brain region, and the kind of proteinopathy.
In the last decades, a vast number of processes have been described as associated
with neurodegenerative diseases, making it increasingly harder to keep an overview
of the big picture forming from all those data. In this meta-study, we analyzed
genomic, transcriptomic, proteomic, and epigenomic data of the aforementioned
diseases using the data of 234 studies in a network-based approach to study
significant general coherences but also specific processes in individual diseases or
omics levels. In the analysis part, we focus on only some of the emerging findings, but
trust that the meta-study provided here will be a valuable resource for various other
researchers focusing on specific processes or genes contributing to the development
of neurodegeneration.
