In a small study of mice with a defective Adenomatous polyposis coli gene, oral administration of zebularine to males had no effect on the overall methylation of DNA or the number of polyps, but in females the average number of polyps was reduced from 58 to 1.[2] It has therefore been suggested for drug use as a prototype of epigenetic therapy for cancer chemoprevention.[3]
