St with the downregulated genes and their possible involvement in pEAE is presented in Table 2. The Gene Ontology biological processes which can be implicated in neurodegeneration, remyelination and connected functions for every gene are also listed, also as associations with chronic EAE processes, differentiation, de/remyelination, neurodegeneration and neuroprotection.Gene Network ConstructionThe gene network construction performed employing the IPA platform aimed at generating a visual tool to assess connections involving differentially expressed genes. The direct or indirect connectivity of genes as disclosed within the literature enables the assessment of connections among any two provided genes. A network was constructed for the upregulated genes with 3fold enhance (Fig 2). A sizable variety of functional direct and indirect connections may be seenPLOS A single | DOI:ten.1371/journal.pone.0157754 June 29,5 /Transcriptional Alterations in the Progressive Experimental Encephalomyelitis Biozzi ABH Mouse ModelFig 1. Identification of differentially expressed genes. (A) MA plot representing the ratio of FPKM expression values between chronic relapsing secondary progressive EAE samples and control samples plotted against their average. All 14,373 genes are plotted with drastically regulated genes (q0.05) plotted in red. (B) Volcano plot presenting the 14,373 genes, with genes more than the significance reduce off at p 0.0072 (log p 2.1426) plotted in grey. The statistically considerable genes with 2fold adjust in expression are plotted in red. doi:10.1371/journal.pone.0157754.gPLOS One | DOI:10.1371/journal.pone.0157754 June 29,six /Transcriptional Modifications inside the Progressive Experimental Encephalomyelitis Biozzi ABH Mouse ModelTable 1.
