Calponin 3 (CNN3), melanoma cell adhesion molecule (MCAM, also named CD146), chemerin (also known as retinoic acid receptor responder protein 2 (RARRES2)), retinol-binding protein 1 (RBP1), growth differentiation factor 15 (GDF15), G protein-coupled receptor 17 (GPR17), and cysteamine (2-aminoethanethiol) dioxygenase (ADO) can induce the phosphorylation of p65 to promote GBM cell proliferation [65,66,67,68,69,70,71]. Here, RARRES2 is linked to glioblastoma.
