Genetic and DNA methylation changes in cotton (Gossypium) genotypes and tissues. [PDF]

open access: yesPLoS ONE, 2014
In plants, epigenetic regulation is important in normal development and in modulating some agronomic traits. The potential contribution of DNA methylation mediated gene regulation to phenotypic diversity and development in cotton was investigated between

The Role of Host Cell DNA Methylation in the Immune Response to Bacterial Infection

open access: yesFrontiers in Immunology, 2021
Host cells undergo complex transcriptional reprogramming upon infection. Epigenetic changes play a key role in the immune response to bacteria, among which DNA modifications that include methylation have received much attention in recent years.

DNA methylation methods: Global DNA methylation and methylomic analyses

open access: yesMethods, 2021
DNA methylation provides a pivotal layer of epigenetic regulation in eukaryotes that has significant involvement for numerous biological processes in health and disease. The function of methylation of cytosine bases in DNA was originally proposed as a "silencing" epigenetic marker and focused on promoter regions of genes for decades.

DNA methylation and DNA methyltransferases [PDF]

open access: yesEpigenetics & Chromatin, 2017
The prevailing views as to the form, function, and regulation of genomic methylation patterns have their origin many years in the past, at a time when the structure of the mammalian genome was only dimly perceived, when the number of protein-encoding mammalian genes was believed to be at least five times greater than the actual number, and when it was ...

DNA methylation analysis

open access: yesSwiss Medical Weekly, 2013
DNA methylation, the addition of a methyl group to cytosines and adenosines, regulates gene expression on a level that is usually referred to as epigenetic, that is, stably maintained during cell divisions. In humans, aberrant DNA methylation is associated with several malignancies, including cancer and so-called imprinting disorders, making it an ...

Genome-wide profiling of DNA methylation and gene expression in Crassostrea gigas male gametes

open access: yesFrontiers in Physiology, 2014
DNA methylation patterns and functions are variable across invertebrate taxa. In order to provide a better understanding of DNA methylation in the Pacific oyster (Crassostrea gigas), we characterized the genome-wide DNA methylation profile in male gamete

Apoptosis and DNA Methylation [PDF]

open access: yesCancers, 2011
Epigenetic mechanisms assist in maintaining gene expression patterns and cellular properties in developing and adult tissues. The molecular pathology of disease states frequently includes perturbation of DNA and histone methylation patterns, which can activate apoptotic pathways associated with maintenance of genome integrity.

Evaluation of the usefulness of saliva for DNA methylation analysis in cohort studies

open access: yesNeuropsychopharmacology Reports, 2019
Introduction Epigenetic information such as DNA methylation is a useful biomarker that reflects complex gene‐environmental interaction. Peripheral tissues such as blood and saliva are commonly collected as the source of genomic DNA in cohort studies ...

Minimal evidence for consistent changes in maize DNA methylation patterns following environmental stress.

open access: yesFrontiers in Plant Science, 2015
DNA methylation is a chromatin modification that is sometimes associated with epigenetic regulation of gene expression. As DNA methylation can be reversible at some loci, it is possible that methylation patterns may change within an organism that is ...

Sex-specific variations in global DNA methylation levels with age: a population-based exploratory study from North India

open access: yesFrontiers in Genetics, 2023
Purpose: Aging is one of the most important risk factors for a number of human diseases. Epigenetic alterations, including changes in DNA methylation patterns, have been reported to be one of the hallmarks of aging. Being a malleable process, the role of
