Interestingly, among the transcripts down-regulated in DUSP8-GFP GdEC#1 and up-regulated in sh-DUSP8-GFP GdEC#1 we found periostin (POSTN) a matricellular protein that has been associated with glioma progression, particularly with glioma angiogenesis [34]. The gene discussed is POSTN; the disease is glioma.
