Deaminase-independent inhibition of parvoviruses by the APOBEC3A cytidine deaminase.

PLoS Pathogens, 2009
The APOBEC3 proteins form a multigene family of cytidine deaminases with inhibitory activity against viruses and retrotransposons. In contrast to APOBEC3G (A3G), APOBEC3A (A3A) has no effect on lentiviruses but dramatically inhibits replication of the ...

The antilymphocytic activity of brequinar sodium and its potentiation by cytidine: Effects on lymphocyte proliferation and cytokine production [PDF]

, 1993
Based on its capacity to inhibit de novo pyrimidine biosynthesis by blocking dihydroorotate dehydrogenase activity, the antitumor agent brequinar sodium (BQR) has emerged as a new immunosuppressive agent.

Genotoxic stress and viral infection induce transient expression of APOBEC3A and pro-inflammatory genes through two distinct pathways

Nature Communications, 2021
The cytidine deaminase APOBEC3A is a main source of mutagenesis in many types of cancer. Here the authors reveal that transient up-regulation of APOBEC3A and other pro-inflammatory genes can occur due to viral infection and genotoxic stress via multiple ...

p53 independent epigenetic-differentiation treatment in xenotransplant models of acute myeloid leukemia [PDF]

, 2011
Suppression of apoptosis by TP53 mutation contributes to resistance of acute myeloid leukemia (AML) to conventional cytotoxic treatment. Using differentiation to induce irreversible cell cycle exit in AML cells could be a p53-independent treatment ...

Contribution of Cytidine Deaminase to Thymidylate Biosynthesis in Trypanosoma brucei: Intracellular Localization and Properties of the Enzyme

mSphere, 2019
Cytidine deaminase (CDA) is a pyrimidine salvage enzyme that catalyzes cytidine and deoxycytidine hydrolytic deamination to yield uridine and deoxyuridine.

Increasing fidelity and efficiency by modifying cytidine base-editing systems in rice

Crop Journal, 2020
The efficiency of plant cytidine base-editing systems is limited, and unwanted mutations frequently occur in transgenic plants. We increased the cytidine editing frequency and fidelity of the plant base editor 3 (BE3) and targeted activation-induced ...

DNA demethylation pathways: Additional players and regulators. [PDF]

, 2017
DNA demethylation can occur passively by "dilution" of methylation marks by DNA replication, or actively and independently of DNA replication. Direct conversion of 5-methylcytosine (5mC) to cytosine (C), as originally proposed, does not occur.

Gender effects on cytidine analogue metabolism and myelodysplastic syndrome treatment outcomes [PDF]

, 2012
In vivo, half-lives of cytidine analogues such as 5-azacytidine and decitabine, used to treat myelodysplastic syndromes (MDS), are determined largely by cytidine deaminase (CDA), an enzyme that rapidly metabolizes these drugs into inactive uridine ...
