In utero tobacco smoke exposure, DNA methylation, and asthma in Latino children. [PDF]
, 2019 BackgroundMaternal smoking during pregnancy is a risk factor for chronic disease later in life and has been associated with variability of DNA methylation at specific cytosine-phosphate-guanine (CpG) loci.

DNA methylation in development [PDF]
, 2012 Early embryonic development is a very precise and complicated process. When a sperm meets an egg, a series of well-orchestrated changes take place, which end up with distinct types of cells that make up an organism. Cells start from a pluripotent state and differentiate without changes in DNA sequence. A differentiated cell shares the same DNA sequence

Molecular Oncology, EarlyView.This study simultaneously investigated circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients. The elevated expression of JUNB and CXCR4 in CTCs was a poor prognostic factor for SCLC patients, whereas exosomal overexpression of these biomarkers revealed a high discrimination ability of patients from healthy individuals,

DNA methylation underpins the epigenomic landscape regulating genome transcription in Arabidopsis
Genome Biology, 2022 Background It is challenging to determine the effect of DNA methylation on the epigenetic landscape and the function in higher organisms due to the lack of DNA methylation-free mutants.

Molecular Oncology, EarlyView.Vulnerability to the small molecule STF‐62247 is observed in SETD2‐inactivated VHL‐positive clear cell renal cell carcinoma (ccRCC) cells. DNA damage and loss of CDC25A leads to cell cycle arrest in S phase. Cleavage of caspase‐3 (CASP3) and gasdermin E (GSDME) suggests cell death by pyroptosis.

Specific or not specific recruitment of DNMTs for DNA methylation, an epigenetic dilemma
Clinical Epigenetics, 2018 Our current view of DNA methylation processes is strongly moving: First, even if it was generally admitted that DNMT3A and DNMT3B are associated with de novo methylation and DNMT1 is associated with inheritance DNA methylation, these distinctions are now

IDN1 and IDN2 are required for de novo DNA methylation in Arabidopsis thaliana. [PDF]
, 2009 DNA methylation is an epigenetic mark affecting genes and transposons. Screening for mutants that fail to establish DNA methylation yielded two we termed "involved in de novo" (idn) 1 and 2.

Molecular Oncology, EarlyView.This study shows that patients with gastrointestinal adenocarcinomas can be stratified into six distinct subtypes based on genome‐scale DNA methylation profiling. This stratification, achieved using a robust analytical framework, aligns with established tumor characteristics and holds potential to support prognostication.

Discovery and optimization of cell-type-specific DNA methylation markers for in silico deconvolution [PDF]
arXiv, 2023 DNA methylation is a significant driver of cell-type heterogeneity and has been implicated in various regulatory processes ranging from cell differentiation to imprinting. As the methyl group is embedded in the DNA molecule, assessing DNA methylation is particularly promising in liquid-biopsy-based approaches, as cell-free DNA retains information ...

Methylation of Replicating and Nonreplicating DNA in the Ciliate \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]
, 1989 Methylation of adenine in replicating and nonreplicating DNA of the ciliate Tetrahymena thermophila was examined. In growing cells, 87% of the methylation occurred on the newly replicated daughter strand, but methylation was also detectable on the ...
