Genes that were persistently upregulated in both age groups included transcripts of the TGF-beta signalling pathway involved in CNS vascular remodelling and angiogenesis including, Eng, Gpc3, Mmp14, Scpep1, Tgfbr2 the latter being more strongly upregulated in aged (3-fold) than in young rats during the recovery phase of stroke. Here, SCPEP1 is linked to Stroke.
