In humans, the DHFR enzyme is encoded by the DHFR gene. Malabsorption in pernicious anemia results from the lack or loss of intrinsic factor needed for the absorption of vitamin B 12. Pernicious anemia is a type of vitamin B 12 deficiency anemia, a disease in which not enough red blood cells are produced due to the malabsorption of vitamin B 12.

Folate supplementation indications include preventing several diseases such as ulcerative colitis, 5-FU converts to fluoro-deoxy uridylic acid, a molecule that functions to inhibit thymidylate synthase. Common genetic variants in the coding of this gene affect more than half the population. 1. An enzyme inhibitor is a molecule that binds to an enzyme and blocks its activity. 1 mM DMOG treatment for 8 h is used to upregulate the HIF-1 protein level in NR8383 cells (B). The conversion is catalyzed by thymidylate synthase. Many are primarily DHFR inhibitors, but raltitrexed is an inhibitor of thymidylate synthase, and pemetrexed inhibits both and a third enzyme. Leucovorin is a folate analog. Enzymes are proteins that speed up chemical reactions necessary for life, in which substrate molecules are converted into products.

At least three alternatively spliced variants encoding distinct proteins have been reported, two of which encode structurally related isoforms known to function as inhibitors of CDK4 kinase. This gene is a proto-oncogene and encodes a nuclear phosphoprotein that plays a role in cell cycle progression, apoptosis and cellular transformation. Methotrexate-polyglutamate further inhibits the de novo purine synthesis of both purine and thymidylate synthase, thereby inhibiting DNA synthesis. Leucovorin is readily converted to another reduced folate, 5,10-methylenetetrahydrofolate, which acts to stabilize the binding of uorode oxyridylic acid to thymidylate synthase and thereby enhances the inhibition of this enzyme. To predict the response or toxicity of MTX in patients with RA, a study by Bae et al. To predict the response or toxicity of MTX in patients with RA, a study by Bae et al.
