OR2B2 and acute myeloid leukemia: For this reason, knowing that ORs with phylogenetic proximity tend to respond similarly to the same odorants [72,73], we selected two AML cell lines known to express OR2B2, MOLM-13 (AML FAB M5a cell line, confirmed both in RNA-Seq and rt-PCR analysis) and Kasumi-1 (AML FAB M2 cell line, negative in RNA-Seq analysis but positive in rt-PCR) and treated with eugenyl acetate [74] and cinnamaldehyde [75,76], two ligands of OR2B11, which belongs to the same phylogenetic family of OR2B2.
