OR51B5 and OR1G1 have been previously found in various cell types; for example, OR51B5 in keratinocytes (Tsai et al. 2017), K562 leukemia cells (Manteniotis et al. 2016), while OR1G1 was detected in Dermal papilla cells (DPCs) (Park et al. 2020) and primary iliac Enterochromaffin cells (Braun et al. 2007). This evidence concerns the gene OR1G1 and leukemia.
