DNA Methylation, Its Mediators and Genome Integrity
DNA methylation regulates many cellular processes, including embryonic development, transcription, chromatin structure, X-chromosome inactivation, genomic imprinting and chromosome stability. DNA methyltransferases establish and maintain the presence of 5-methylcytosine (5mC), and ten-eleven translocation cytosine dioxygenases (TETs) oxidise 5mC to 5-hydroxymethylcytosine (5hmC), 5-formylcytosi...
متن کاملNoncoding RNAs and DNA Methylation in Plants.
Cytosine DNA methylation is an epigenetic modification in eukaryotes that maintains genome integrity and regulates gene expression. The DNA methylation patterns in plants are more complex than those in animals, and plants and animals have common as well as distinct pathways in regulating DNA methylation. Recent studies involving genetic, molecular, biochemical and genomic approaches have greatl...
متن کاملDNA Methylation and Its Role in the Development of Leukemia
Epigenetic changes play an essential role in cancer pathogenesis. It has been established by next-generation sequencing that more than 50% of the human cancers carry mutations in mechanisms involved in the organization of the chromatin and epigenetic regulations. DNA methylation is among the most common epigenetic changes in leukemia. In contrast to DNA mutations which are passively inherited f...
متن کاملThe role and importance of DNA methylation in spermatogenesis process
Background: DNA methylation is one of the epigenetic marks that are created by de novo DNA methylation and be maintained through cell division. This process is catalyzed by DNA methyltransferases. DNA methylation establishment in germ line is important, since they have the potential to regulate gene expression in offspring and improper DNA methylation patterns in germ lines has serious conseque...
متن کاملDNA methylation and epigenetic inheritance in plants and filamentous fungi.
Plants and filamentous fungi share with mammals enzymes responsible for DNA methylation. In these organisms, DNA methylation is associated with gene silencing and transposon control. However, plants and fungi differ from mammals in the genomic distribution, sequence specificity, and heritability of methylation. We consider the role that transposons play in establishing methylation patterns and ...
