Abstract

Ischemic stroke (IS) is characterized by high morbidity and poor prognosis. However, the mechanisms of IS induced injury are still poorly understood. The main aim of this study is to explore the role of autophagy in IS. Ten pairs of whole blood samples of IS patients and matched controls were included to select differential expressed genes (DE genes) by autophagy-related functional gene microarray analysis. And then, one hundred and fifty pairs of whole blood samples of IS patients and matched controls were included to validate the DE genes. Moreover, Gene Ontology (GO) analyses and Pathway analyses were also performed based on the DE gene results. Our results indicated that the co-regulation of autophagy and apoptosis took part in IS-induced injuries, and mitochondrial autophagy and apoptosis played a crucial role in this process. Furthermore, lysosome, protein kinase and endopeptidase also participated in IS. These findings clarified the role of mitochondrial autophagy and apoptosis in ischemic stroke and provided more important biomarkers for the prevention diagnosis and therapeutic implications in IS.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Autophagy & Model Organisms

Autophagy is a cellular process that allows degradation by the lysosome of cytoplasmic components such as proteins or organelles. Here is the latest research on autophagy & model organisms

Autophagy Networks

Autophagy is a lysosomal pathway that involves degradation of proteins and functions in normal growth and pathological conditions, through a series of complex networks. The catabolic process involves delivery of proteins and organelles to the lysosome. Here is the latest research on autophagy networks.
