The following will concentrate on the enzymes that can affect BH4 levels and its relationship to histamine; Methyltetrahydrafolate reductase (MTHFR), dihydropteridine reductase, dihydrofolate reductase (DHFR), and quinoid dihydropteridine reductase (QDPR) heavily influence BH4 (tetrahydrobiopterin) synthesis and recycling.
[sup][35],[36],[37] In addition, a SNP 829C-T near the miR-24 binding site in the 3′ UTR of dihydrofolate reductase was closely associated with methotrexate resistance by interfering with miR-24 function, [sup][38] while SNPs in miRNAs lead to altered expression levels and functions of miRNA, resulting in an increased risk of illness.
Methotrexate works by blocking the action of a key enzyme, dihydrofolate reductase (DHFR), which cancer cells require to thrive.
