Similarly, in rectal cancer, NMB expression exhibited significant correlations (P < 0.001; correlation coefficient ≥ 0.40) with markers including CD3E, HAVCR2, IL10, CD1C, CEACAM8, CCR7, STAT3, CTLA4, ITGAM, HLA-DPB1, FOXP3, CCL2, KIR3DL1, and STAT1. The gene discussed is KIR3DL1; the disease is rectal cancer.
