CNPY4 and glioblastoma: Simultaneously, we explored the cumulative survival of CNPY4 in GBM and LGG tissues and found that B cells, T cells, macrophages, neutrophils, dendritic cells and CNPY4 were the survival indices for LGG patients, whereas, in GBM patients, only B cells and dendritic cells were related to survival (Fig. 5B).
