DLK2 and nonpapillary renal cell carcinoma: From the SCNA module of the TIMER tool, arm-level deletion of the DLK2 gene caused the reduction of B cell (** p < 0.01), CD8+ T cells (** p < 0.01), CD4+ T cells (** p < 0.01), neutrophil (** p < 0.01), and dendritic cell infiltrations (** p < 0.01) in ccRCC (Figure 10).
