The maintenance DNA methyltransferase (DNMT) 1 and the de novo methyltransferases DNMT3A and DNMT3B are all essential for mammalian development. DNA methylation, catalyzed by the DNMTs, plays an important role in maintaining genome stability.

The DNA methyltransferase (DNMT) family comprises a conserved set of DNA-modifying enzymes that have a central role in epigenetic gene regulation. Recent studies have shown that the functions of the canonical DNMT enzymes - DNMT1, DNMT3A and DNMT3B - go beyond their traditional roles of establishing …

DNA methyltransferases (DNMTs) are the writers of the epigenome. DNMTs are a highly conserved family of proteins present in nearly all life on earth. In mammals, there are 3 major DNMTs: DNMT1, DNMT3a and DNMT3b. DNMT1 is a maintenance DNMT, while DNMT3a and 3b are de novo DNMTs.

2017年10月16日 · DNMTs are important for normal mammalian development, and DNMT mutations are associated with several human diseases, including cancer. The DNA methyltransferase (DNMT) family comprises a...

2024年12月24日 · DNMT1 (DNA Methyltransferase 1) is a Protein Coding gene. Diseases associated with DNMT1 include Cerebellar Ataxia, Deafness, And Narcolepsy, Autosomal Dominant and Neuropathy, Hereditary Sensory, Type Ie. Among its related pathways are RNA Polymerase I Promoter Opening and Signaling by ALK fusions and activated point mutants.

DNA methyltransferases (DNMTs) is involved for DNA methylation, which are responsible for adding a methyl group to the fifth carbon atom of the cytosine residues within cytosine-phosphate-guanine (CpG) and non-CpG dinuclotide sites. Five DNMT enzymes have been identified in mammals including DNMT1, DNMT2, DNMT3A, DNMT3B, and DNMT3L.

2025年3月19日 · DNMT inhibitors reduce methylation, disrupting these repressive complexes and increasing histone acetylation, leading to a more open chromatin state. This has led to therapeutic strategies combining DNMT and HDAC inhibitors, with studies showing dual inhibition can more effectively restore gene expression in diseases driven by epigenetic silencing.

2025年1月17日 · DNA methylation, catalyzed by DNA methyltransferases (DNMT), plays pivotal role in regulating embryonic development, gene expression, adaption to environmental stress, and maintaining genome integrity. DNMT family consists of DNMT1, DNMT3A, DNMT3B, and the enzymatically inactive DNMT3L.

2025年3月21日 · Treatment with decitabine (DAC), a US Food and Drug Administration–approved nucleoside-based pan-DNMT inhibitor (fig. S2A) , also up-regulated NKp30 and NKp46 in primary human T cells (fig. S2B) and NK1.1 in murine T cells (fig. S2, C and D). DAC treatment enhanced murine CD8 T cell killing capability toward B16F10 cell lines (fig. S2E) and ...

DNA methylation is an epigenetic mark that living beings have used in different environments. The MTases family catalyzes DNA methylation. This process is conserved from archaea to eukaryotes, from fertilization to every stage of development, and …
