This study aimed to investigate the expression profiles and regulatory mechanisms of TNF-α and its downstream mediators—including interleukin-1 beta (IL-1β), Mitogen-Activated Protein Kinase Kinase Kinase 8 (MAP3K8), and Mitogen-activated protein kinase kinase 7 (MAP2K7)—in astrocytic tumors of varying malignancy. This evidence concerns the gene MAPK8 and astrocytic tumor.
