Nicotinamide N-Methyltransferase (NNMT) methylates nicotinamide and other pyridine containing compounds.{24617} NNMT transfers a methyl group from S-adenosylmethionine (SAM) to nitrogen N1 of nicotinamide to produce 1-methylnicotinamide (MNA) and S-adenosylhomocysteine. MNA is a messenger molecule that increases neurite branching, serves as an anti-thrombotic, and has anti-inflammatory properties.{24616,24618,24614} Overexpression of NNMT has been reported in several cancers. Knockdown of NNMT by shRNA lowers the invasiveness of clear cell renal cell carcinoma, and slows the growth of oral squamous cell carcinoma tumors injected into mice.{24615,24613} The role of NNMT overexpression in cancers may be to alter epigenetic methylation patterns in two ways: by lowering the intracellular concentration of SAM, required by methyltransferase enzymes, and by depleting the available NAD+ by transforming nicotinamide to MNA.{24614,24772} Sirtuins use NAD+ as a substrate to alter protein acetylation and ribosylation, including histone targets.{24614}
