To better understand the contribution of dysregulated DNA methyltransferase 1 (DNMT1) expression to the progression and biology of clear cell renal cell carcinoma (ccRCC). We examined the differences in the expression of DNMT1 in 89 ccRCC and 22 normal tissue
Arul J Duraisamy et al.
Biochimica et biophysica acta. Molecular basis of disease, 1865(6), 1617-1626 (2019-03-30)
Mitochondria are dynamic in structure, and undergo continuous fusion-fission to maintain their homeostasis. In diabetes, retinal mitochondria are swollen, their membrane is damaged and mitochondrial fusion protein, mitofusin 2 (Mfn2), is decreased. DNA methylation machinery is also activated and methylation
Laura P Sutton et al.
Epigenetics, 14(10), 989-1002 (2019-06-19)
Many cancer therapies operate by inducing double-strand breaks (DSBs) in cancer cells, however treatment-resistant cells rapidly initiate mechanisms to repair damage enabling survival. While the DNA repair mechanisms responsible for cancer cell survival following DNA damaging treatments are becoming better
Carlos Alberto Valencia Antúnez et al.
Oncology reports, 32(5), 2093-2103 (2014-09-06)
Carcinogenesis is driven by the accumulation of mutations and abnormal DNA methylation patterns, particularly the hypermethylation of tumor‑suppressor genes. Changes in genomic DNA methylation patterns are established by the DNA methyltransferases (DNMTs) family: DNMT1, DNMT3a and DNMT3b. The DNMTs are
Rajiv P Sharma et al.
Neuropsychopharmacology : official publication of the American College of Neuropsychopharmacology, 35(10), 2009-2020 (2010-07-16)
The study of CpG methylation of genomic DNA in neurons has emerged from the shadow of cancer biology into a fundamental investigation of neuronal physiology. This advance began with the discovery that catalytic and receptor proteins related to the insertion
Laccaic Acid A Is a Direct, DNA-competitive Inhibitor of DNA Methyltransferase 1
Fagan RL, et al.
The Journal of Biological Chemistry, 288(33), 23858-23858 (2013)
Depolarization induces downregulation of DNMT1 and DNMT3a in primary cortical cultures.
Sharma, et al.
Epigenetics, 3, 74-80 (2019)
M R Rountree et al.
Nature genetics, 25(3), 269-277 (2000-07-11)
DNA methylation can contribute to transcriptional silencing through several transcriptionally repressive complexes, which include methyl-CpG binding domain proteins (MBDs) and histone deacetylases (HDACs). We show here that the chief enzyme that maintains mammalian DNA methylation, DNMT1, can also establish a
Mina Sasaki et al.
Biochemical and biophysical research communications, 452(3), 622-628 (2014-09-03)
Reactive oxygen species (ROS) can cause severe damage to DNA, proteins and lipids in normal cells, contributing to carcinogenesis and various pathological conditions. While cellular senescence arrests the early phase of cell cycle without any detectable telomere loss or dysfunction.
Li Zhang et al.
Kidney international, 92(1), 140-153 (2017-03-21)
The contribution of DNA methylation to diabetic nephropathy, especially the effect on podocyte integrity, is not clarified. Here we found that albuminuria in a db/db mouse model was markedly attenuated after treatment with a DNA methylation inhibitor. This was accompanied
Qiong Zhu et al.
Journal of molecular neuroscience : MN, 46(2), 420-426 (2011-08-10)
DNA methylation is a key epigenetic modification of DNA that is catalyzed by DNA methyltransferase (DNMT). Increasing evidence suggests that DNA methylation in neurons regulates synaptic plasticity as well as neuronal network activity. Here, we evaluated DNA methyltransferase 1 (Dnmt1)
Michalina Alicka et al.
Stem cell research & therapy, 11(1), 4-4 (2020-01-05)
Progressive loss of cell functionality caused by an age-related impairment in cell metabolism concerns not only mature specialized cells but also its progenitors, which significantly reduces their regenerative potential. Adipose-derived stem cells (ASCs) are most commonly used in veterinary medicine
Depolarization induces downregulation of DNMT1 and DNMT3 in primary cortical cultures
Sharma RP, et al.
Epigenetics, 3(2), 74- 80 (2008)
I Rhee et al.
Nature, 404(6781), 1003-1007 (2000-05-09)
Hypermethylation is associated with the silencing of tumour susceptibility genes in several forms of cancer; however, the mechanisms responsible for this aberrant methylation are poorly understood. The prototypic DNA methyltransferase, DNMT1, has been widely assumed to be responsible for most
Xiangmei Wu et al.
Molecular neurobiology, 50(3), 839-851 (2014-04-15)
Chronic cerebral hypoperfusion is associated with cognitive decline in aging and age-related neurodegenerative disease. Epigenetic mechanisms are involved in the maintenance of long-term hypoxia-adapted cellular phenotypes. In the present study, the epigenetic signatures such as DNA methylation and histone acetylation
Bo Ra You et al.

Zebularine (Zeb) is a DNA methyltransferase (DNMT) inhibitor to that has an anti-tumor effect. Here, we evaluated the anti-growth effect of Zeb on A549 lung cancer cells in relation to reactive oxygen species (ROS) levels. Zeb inhibited the growth of
Eriko G Clements et al.
Nucleic acids research, 40(10), 4334-4346 (2012-01-27)
While DNA methyltransferase1 (DNMT1) is classically known for its functions as a maintenance methyltransferase enzyme, additional roles for DNMT1 in gene expression are not as clearly understood. Several groups have shown that deletion of the catalytic domain from DNMT1 does

People with type 2 diabetes mellitus (T2DM) have a 25-fold higher risk of limb loss than non-diabetics due in large part to impaired wound healing. Here, we show that the impaired wound healing phenotype found in T2D mice is recapitulated

Benzo(a)pyrene (BaP) is a known carcinogen cytotoxic which can trigger extensive cellular responses. Many evidences suggest that inhibitors of poly(ADP-ribose) glycohydrolase (PARG) are potent anticancer drug candidates. However, the role of PARG in BaP carcinogenesis is less understood. Here we
