C3AR1 and glioblastoma: 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).
