BMP1 and nonpapillary renal cell carcinoma: As presented in Table 2, Expression of BMP1 correlated significantly positively with B-cell biomarkers (CD19 and CD79A), CD4+ T-cellcell biomarkers (CD4), CD8+ T-cell biomarkers (CD8B), neutrophil biomarkers (ITGAM and CCR7), M1 macrophage biomarkers (NOS2, PTGS2, and IRF5), M2 macrophage biomarkers (CD163, VSIG4, and MS4A4A) and dendritic cell biomarkers (HLA-DPB1, CD1C, NRP1, and ITGAX) in ccRCC.
