What is the role of 5-azacytidine in cancer treatment?
5-AZA-CdR can reactivate tumor suppressor genes silenced by aberrant DNA methylation, a frequent event in all types of cancer. Because this epigenetic change is reversible, it is a good target for 5-AZA-CdR therapy.
How does 5-azacytidine affect gene expression?
5-azacytidine (5-azaC) is used as an experimental tool for demethylation and it induces differentiation in various systems. In the chick embryo, the first cellular migrations signal the onset of primitive streak and gastrula formation and result in neural induction and morphogenesis of the embryonic axis.
How do you dissolve 5-azacytidine?
5-Azacytidine is supplied as a crystalline solid. A stock solution may be made by dissolving the 5-azacytidine in the solvent of choice, which should be purged with an inert gas. 5-Azacytidine is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide.

We strongly recommend that patients be treated with azacitidine for a minimum of 6 months, and that in patients who achieve a documented response or stable disease (sd), treatment be continued until disease progression or unacceptable toxicity occurs.
Can azacitidine cure MDS?
Azacitidine is a chemotherapy drug, however, it is a “hypomethylating agent”. Hypomethylating agents are considered a non-intensive treatment. They are aimed at slowing the progression of the disease with as few side effects as possible, maintaining a good quality of life. They will not cure MDS but may ‘modify’ it.
