Abstract
Sleep deprivation leads to the deterioration in physiological functioning of the brain, cognitive decline, and many neurodegenerative diseases, all which progress with advancing age. Sleep insufficiency and impairments in cognitive function are characterized by progressive neuronal losses in the cerebral cortex. In this study, we analysed gene expression profiles following sleep deprived murine models and circadian matched controls to identify genes that might underlie cortical homeostasis in response to sleep deprivation. Screening of the literature resulted in three murine (Mus musculus) gene expression datasets (GSE6514, GSE78215, and GSE33491) that included cortical tissue biopsies from mice that were sleep deprived for 6 hours (n = 15) and from circadian controls that were left undisturbed (n = 15). Cortical differentially expressed genes were used to construct a network of encoded proteins that were ranked based on their interactome according to 11 topological algorithms. The analysis revealed three genes– NFKBIA, EZR and SGK1 – which exhibited the highest multi-algorithmic topological significance. These genes are strong markers of increased brain inflammation, cytoskeletal aberrations, and glucocorticoid resistance, changes that imply aging-like transcriptional responses during sleep deprivation in the murine cortex. Their potential role as candidate markers of local homeostatic response to sleep loss in the murine cortex warrants further experimental validation.
