It was found that RBM38 was related to tumor purity (r = −0.097, p = 0.037), B cell infiltration (r = 0.271, p < 0.001), CD4+ T infiltration (r = 0.264, p < 0.001), neutrophil infiltration (r = 0.132, p = 0.005), and dendritic cell infiltration (r = 0.24, p < 0.001) (Figure 4A). This evidence concerns the gene CD4 and neoplasm.
