DNA methylation and demethylation dynamics
Oncotarget, 2015 DNA methylation is one of the most studied epigenetic modifications and is essential for mammalian development. The methylation pattern is established through an extremely orchestrated mechanism that implicates de novo methylation, maintenance of the methylated cytosine, and demethylation.

Active DNA Demethylation Mediated by DNA Glycosylases [PDF]
Annual Review of Genetics, 2009 Active DNA demethylation is involved in many vital developmental and physiological processes of plants and animals. Recent genetic and biochemical studies in Arabidopsis have demonstrated that a subfamily of DNA glycosylases function to promote DNA demethylation through a base excision-repair pathway.

Genome-wide DNA demethylation in mammals [PDF]
Genome Biology, 2010 The cytidine deaminase AID and elongator-complex proteins contribute to the extensive removal of DNA methylation in mammalian primordial germ cells and in the paternal pronucleus of the zygote.

Molecular Oncology, EarlyView.Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

BioChem, 2022 Three forms of methylated cytosines are present in the eukaryotic genome: 3-methylcytosine, 4-methylcytosine and 5-methylcytosine. 3-methylcytosines create methyl lesions, which impair local DNA function and flexibility, resulting in replication and ...

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance
Aging and Cancer, EarlyView.NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Angewandte Chemie, EarlyView.The carbocyclic Decitabine analog (cAzadC) incorporates as an antimetabolite weakly into the genome of growing tumor cells, where it triggers a genome‐wide demethylation and a surprisingly strong hydroxymethylation of cytosine, which translates into an efficient in vivo antitumor (AML) effect.

Epigenetic modification of gene expression in cancer cells by terahertz demethylation
Scientific Reports, 2023 Terahertz (THz) radiation can affect the degree of DNA methylation, the spectral characteristics of which exist in the terahertz region. DNA methylation is an epigenetic modification in which a methyl (CH3) group is attached to cytosine, a nucleobase in ...

The role of DNA demethylation during development [PDF]
Genes to Cells, 1997 The somatic genomic methylation pattern which plays a role in the suppression of basal gene activity is established anew in each generation through developmentally regulated de novo and demethylation steps. Demethylation appears to be carried out by a nucleotide exchange reaction which may involve RNA molecules, and is directed to specific loci in the ...

Advanced Science, EarlyView.Model of circNrip1 (cNrip1) upregulation driving neuropathic pain mechanisms. After peripheral nerve injury, increased FUS triggers the formation and upregulation of cNrip1 in injured DRG neurons. Upregulated cNrip1 recruits SYNCRIP to the 3′‐UTR of Tlr2 mRNA by binding to both, thereby promoting SYNCRIP‐triggered Tlr2 mRNA stability and increasing ...
