200 million people worldwide, maintain NAD homeostasis via the NAD salvage biosynthetic pathway. The transmethylation pathway and methionine salvage pathway (MTA cycle) are two major pathways regulating methionine metabolism. https://doi.org/10.1111/1523-1747.ep12482292. Methotrexate effectively blocked thymidylate synthesis de novo but did not inhibit DNA synthesis as determined by [3H]thymidine incorporation into DNA thymidylate residues or by [14C]deoxycytidine incorporation into DNA deoxycytidylate residues.
