MT2A and red-green color blindness: CBD was associated with higher frequency of consistent DEGs across datasets, such as HMOX1, SLC30A1, MT2A, and SLC39A10. Previous in vitro studies have identified HMOX1 as the most upregulated gene and protein following CBD treatment via CBD-induced nuclear export and proteasomal degradation of transcriptional repressor BACH (Casares et al. 2020).
