Among them, C3AR1, CLCF1, OSMR, KCNN4 and HTR7 were also positively correlated with several genes related to cell–matrix adhesion (e.g., FN1, ITGA3, ITGA5, ITGB1), EMT (e.g., TGFB1, TGFBR2, SNAI1, SNAI2, VIM) and matrix remodelling (e.g., ADAM8, ADAM9, MMP14, MMP19) in GBM (Figure 7C–E). The gene discussed is MMP19; the disease is glioblastoma.
