DNA Methyltransferase
DNMTs; DNA MTases
DNA methyltransferases (DNMTs) are a family of “writer” enzymes responsible for DNA methylation that is the addition of a methyl group to the carbon atom number five (C5) of cytosine. Mammalians encode five DNMTs: DNMT1, DNMT2, DNMT3A-DNMT3B (de novo methyltransferases), and DNMTL. DNMT1, DNMT3A, and DNMT3B are the three active enzymes that maintain DNA methylation. DNMT3L has no catalytic activity and functions as a regulator of DNMT3A and DNMT3B, whereas DNMT2 acts as a tRNA transferase rather than a DNA methyltransferase.
DNA methylation is a vital modification process in the control of genetic information, which contributes to the epigenetics by regulating gene expression without changing the DNA sequence. In prokaryotes, DNA methylation is essential for transcription, the direction of post-replicative mismatch repair, the regulation of DNA replication, cell-cycle control, bacterial virulence, and differentiating self and non-self DNA. In mammalians, DNA methylation is crucial in many key physiological processes, including the inactivation of the X-chromosome, imprinting, and the silencing of germline-specific genes and repetitive elements.

Hydralazine hydrochloride (Standard)
0 ImagesHydralazine (hydrochloride) (Standard) is the analytical standard of Hydralazine (hydrochloride). This product is intended for research and analytical applications. Hydralazine hydrochloride is an orally active, blood-brain barrier-permeable DNA methyltransferase inhibitor with vasodilatory, arterial smooth muscle relaxant and hypotensive activities. Hydralazine hydrochloride reactivates silenced tumor suppressor genes via mediating DNA demethylation, while exerting neuroprotective and anti-inflammatory properties. Hydralazine hydrochloride inhibits NOS-2 (iNOS) and COX-2, and reduces the production of NO and PGEE2; meanwhile, Hydralazine hydrochloride scavenges reactive oxygen species and inhibits macrophage activation. Hydralazine hydrochloride alleviates motor dysfunction, neuropathic inflammatory pain, and formalin-induced somatic and emotional pain responses. In addition, Hydralazine hydrochloride directly induces DNA strand breaks and sister chromatid exchange, exhibiting certain mutagenic characteristics. Hydralazine hydrochloride has been widely used in studies on hypertension, various cancers (such as cervical cancer, leukemia), spinal cord injury and the mechanisms of inflammatory pain.
