Proteomics of In Vivo Models of Ischemic Stroke: A Systematic review with a Systems Biological Perspective

Deregulated proteins in multiple independent studies

A total number of 534 deregulated proteins were manually extracted from the ivProt studies (n=130). Twenty-nine proteins were deregulated in more than one independent study. These proteins were grouped into 4 categories based on sample location, model type, occlusion/ reperfusion, and regulation; 1) Group I- Consistent Regulation Matched Variables, 2) Group II- Consistent Regulation Unmatched Variables, 3) Group III- Inconsistent Regulation, 4) Group IV- Unmatched models-inconsistent regulation. *Group IV has not been discussed in the main text.
