Biochemical engineering of 5hmdC-DNA using a Tet3 double-mutant. [PDF]

open access: yesComput Struct Biotechnol J
5-Hydroxymethyl-2′-deoxycytidine (5hmdC) is an important epigenetic marker involved in gene regulation and DNA demethylation. It has potential use as a biomarker for cancer and other diseases due to its significant depletion in various cancers and ...

Cytosolic CTP Production Limits the Establishment of Photosynthesis in Arabidopsis

open access: yesFrontiers in Plant Science, 2021
CTP synthases (CTPS) comprise a protein family of the five members CTPS1-CTPS5 in Arabidopsis, all located in the cytosol. Specifically, downregulation of CTPS2 by amiRNA technology results in plants with defects in chlorophyll accumulation and ...

Significance of Circulating Cell-Free DNA Biomarkers in HBeAg-Negative Chronic Hepatitis B Virus Infection and Their Changes after Treatment Initiation

open access: yesPathogens, 2023
Background: Chronic hepatitis B virus (HBV) infection is a common chronic liver disease that is closely associated with increased morbidity and mortality. Circulating cell-free DNA (cf-DNA) and global DNA methylation, expressed as circulating levels of 5-

DNA hypomethylation promotes learning and memory recovery in a rat model of cerebral ischemia/reperfusion injury

open access: yesNeural Regeneration Research, 2023
Cerebral ischemia/reperfusion injury impairs learning and memory in patients. Studies have shown that synaptic function is involved in the formation and development of memory, and that DNA methylation plays a key role in the regulation of learning and ...

Global demethylation of rat chondrosarcoma cells after treatment with 5-aza-2'-deoxycytidine results in increased tumorigenicity. [PDF]

open access: yesPLoS ONE, 2009
Abnormal patterns of DNA methylation are observed in several types of human cancer. While localized DNA methylation of CpG islands has been associated with gene silencing, the effect that genome-wide loss of methylation has on tumorigenesis is not ...

Profiles of a broad spectrum of epigenetic DNA modifications in normal and malignant human cell lines: Proliferation rate is not the major factor responsible for the 5-hydroxymethyl-2'-deoxycytidine level in cultured cancerous cell lines. [PDF]

open access: yesPLoS ONE, 2017
Active demethylation of 5-methylcytosine moiety in DNA occurs by its sequential oxidation to 5-hydroxymethylcytosine, 5-formylcytosine and 5-carboxycytosine, catalysed by enzymes of the Ten-Eleven Translocation family proteins (TETs 1, 2 and 3).

A new technique for the analysis of metabolic pathways of cytidine analogues and cytidine deaminase activities in cells

open access: yesScientific Reports, 2023
Deoxycytidine analogues (dCas) are widely used for the treatment of malignant diseases. They are commonly inactivated by cytidine deaminase (CDD), or by deoxycytidine monophosphate deaminase (dCMP deaminase).

Artemisinin DNA Base Interaction Studies in Presence of Fe(II): LC/TOF MS Separation of Reaction Products

open access: yesSeparations, 2021
Artemisinin (ART) is a sesquiterpene lactone and a popular malaria drug with potential anticancer properties. In this work, LC/TOF/MS, was used to investigate the reaction of ART with DNA bases. ART-deoxyadenosine and ART-deoxycytidine interactions, were

DCK is an Unfavorable Prognostic Biomarker and Correlated With Immune Infiltrates in Liver Cancer

open access: yesTechnology in Cancer Research & Treatment, 2020
Background: The biological function of deoxycytidine kinase in tumor is not yet clear, and there are a few studies relating to the correlation of deoxycytidine kinase gene with the occurrence and development of liver cancer.
