In addition, univariate Cox regression analyses indicated significant correlations between the expression of these hub genes (ITGB2, CD53, C3AR1, CYBB, ITGAM, SYP, CPLX1, GABRG2, SLC6A1 and SCRT1) and the prognosis of glioma (Supplementary Fig. S6A-B). The gene discussed is C3AR1; the disease is central nervous system cancer.
