In order to explore whether this contradiction exists in gliomas, we compared the expression levels of vascular stability-related markers (ANGPT1, ANGPT2, JAM2, MCAM, PDGFRB, and VE-Cadherin) in the high- and low-score glioma groups in the TCGA, CGGA, and CGGA (array) datasets. The gene discussed is JAM2; the disease is central nervous system cancer.
