The mechanisms that establish and maintain methylation patterns in the mammalian genome are very poorly understood, even though perturbations of methylation patterns lead to a loss of genomic imprinting, ectopic X chromosome inactivation, and death of mammalian embryos. A family
Treatment of C57BL X DBA/2 F (hereafter called BD2F) mice bearing ascitic mammary adenocarcinoma-755 (ADC-755) with [3H]-5-fluoro-2'-deoxycytidine ([3H]FdCyd) plus tetrahydrouridine (H4Urd) resulted in antimetabolite pool sizes indicative of a tumor-selective, dual pathway metabolism of FdCyd via both cytidine deaminase and

The plasma concentration of 5-fluorouracil (FUra) following the i.v. administration of FUra and guanosine 5'-monophosphate (GMP) or guanosine 5'-triphosphate (GTP) was markedly elevated. These values were more than 5-fold higher than those obtained with FUra alone over 60 min after
The metabolic products formed and incorporated into the nucleic acids (RNA and DNA) of mice bearing Lewis lung carcinoma (LLC) following optimal doses of 5-fluorouracil (FUra), 5-fluoro-2'-deoxyuridine (FdUrd), and 5-fluoro-2'-deoxycytidine (FdCyd) coadministered with tetrahydrouridine (H4Urd), a potent inhibitor of cytidine
Cleavage by restriction endonucleases MvaI kappa EcoRII of DNA duplexes, in which the internal deoxycytidine in one of the strands of the recognition site is substituted for 5-fluorodeoxycytidine, has been studied. It has been found that the modified strands of
We offer a variety of small molecule research tools, such as transcription factor modulators, inhibitors of chromatin modifying enzymes, and agonists/antagonists for target identification and validation in gene regulation research; a selection of these research tools is shown below.
