Formation of 3,N4-ethenocytidine moieties in RNA by vinyl chloride metabolities in vitro and in vivo

Abstract
Rats were exposed to [1,2-14C] vinyl chloride. Liver RNA was isolated, hydrolyzed, and the nucleosides separated on Aminex-A-6. Besides the physiological bases and 1,N6-ethenoadenosine, radioactivity was also incorporated into 3,N4-ethenocytidine. Radioactive 3,N4-ethenocytidine moieties were also formed on incubation of polycytidylic acid with rat liver microsomes, NADPH and [14C] vinyl chloride. These alkylation mechanisms are consistent with the mutagenic and cancerogenic properties of vinyl chloride.
