TGFB1 and Alzheimer disease: For the genes upregulated in Alzheimer’s disease and by glutamate in our study, downregulated by candesartan, and, predominately expressed in endothelial cells, the pathway analysis revealed cellular movement/migration, extracellular matrix proteins, apoptosis, angiogenesis and vasculogenesis, and their most significant upstream regulators are beta-estradiol and TGFβ1 (Additional file 10: Figure S4, Additional file 11: Table S6 and Additional file 12: Table S7).
