Subsequently, a least absolute shrinkage and selection operator (LASSO) Cox regression analysis was implemented based on the 53 genes to establish the prognostic signature for glioma patients, identifying 11 key genes (Figure 3a): PLOD1, CCR5, CTSZ, ITGB2, TLR2, ASPM, GINS4, KIF14, KIF2C, KPNA2, and POLD3. The gene discussed is CCR5; the disease is central nervous system cancer.
