Similarly, other studies demonstrated that targeting of neuron glial antigen 2 or chondroitin sulfate proteoglycan 4 (NG2/CSPG4) with the monoclonal antibody mAb9.2.27 could inhibit tumor growth and prolong survival in GBM-bearing mouse and rat models [99, 100]. This evidence concerns the gene CSPG4 and neoplasm.
