Experimental approaches using small interfering RNA to inhibit uPAR expression or blocking antibody to impair uPAR function can significantly interfere with glioma/glioblastoma invasion in vivo and in vitro and can also downregulate intracellular signalling leading to reduced tumor vascularization, suppress cell survival and proliferation [16, 19, 28, 29, 35]. This evidence concerns the gene PLAUR and central nervous system cancer.
