The results revealed significant associations between FDX1 and various immune-related pathways as well as metabolic responses in GBM, such as interferon gamma response, interferon alpha response, allograft rejection, and oxidative phosphorylation. Furthermore, FDX1 was found to play a role in the regulation of several biological functions, including epithelial mesenchymal transition, apoptosis, G2M checkpoint, and DNA repair (Fig. 7C). Here, FDX1 is linked to glioblastoma.
