Of the 157 genes, 27 were included in the eight pathways described above: 18 genes (IL1B, SUCNR1, MUC1, PLXNB1, IFNB1, OR1L4, MUC16, OR1Q1, GRM1, OR1L8, RAMP1, IFNW1, OR1J1, IL5RA, OR13C4, GDF6, GNG8 and RTP3) were upregulated while nine genes (OR5B12, CLEC10A, CCR5, PDGFA, WNT10A, DAGLA, TNFSF15, TNFRSF11A, and CSF1R) were downregulated in the PD-AML group, compared with the PND-AML group (Figure 1). This evidence concerns the gene OR1L4 and acute myeloid leukemia.
