It incorporates into DNA strands upon replication, and then when DNA methyltransferases (DNMTs) such as DNMT1, are engaged to bind the DNA and to replicate the methylation to the daughter strand, DNMTs are bound to decitabine irreversibly and cannot disengage. Therefore, the action of decitabine is division-dependent, meaning the cells have to divide in order for the pharmaceutical to act. |
|||
Piml, J.; Sorm, F.; Coll. Czech. Chem. Commun. 1964, 29, 2576. |
|||
Therefore, cancer cells which divide much more rapidly than most other cells in the body will be more severely affected by decitabine just because they replicate more. It seems that DNA hypermethylation is critical for development of cancer cells, and specifically for haematological malignancies. Methylation of CpG islands upstream of tumor suppressor genes in order to silence them seems to be critical for these type of cancers. Thus at optimal doses, decitabine blocks this type of methylation and has an anti-[[Neoplasm|neoplastic]] effect. |

===Atherosclerosis=== |
|||
⚫ | |||
A number of investigators have shown a relationship between [[atherosclerosis]] and disturbed blood flow. This upregulates DNA [[methyltransferase]] expression, which leads to genome-wide DNA methylation alterations and global gene expression changes. These studies have revealed several mechanosensitive genes, such as HoxA5, Klf3, and Klf4, whose promoters were hypermethylated by disturbed blood flow, but rescued by DNA methyltransferases inhibitors such as 5-aza-2'-deoxycytidine. It has been found that use of this DNA methyltranferase inhibitor prevents atherosclerosis lesion formation and reduces the production of inflammatory [[cytokine]]s by [[macrophages]].<ref>{{cite journal | vauthors = Dunn J, Thabet S, Jo H | title = Flow-Dependent Epigenetic DNA Methylation in Endothelial Gene Expression and Atherosclerosis | journal = Arteriosclerosis, Thrombosis, and Vascular Biology | volume = 35 | issue = 7 | pages = 1562–1569 | date = July 2015 | pmid = 25953647 | pmc = 4754957 | doi = 10.1161/atvbaha.115.305042 }}</ref> |
