different levels of global methylation in the adult rat dentate gyrus and CA1 region in comparison with the CA2 and CA3 regions. mRNA levels of DNA methyltransferases exhibit similar regional specificity and are correlated with global DNA methylation levels
pleomorphic adenoma, adenoid cystic carcinoma, mucoepidermoid carcinoma and polymorphous low-grade adenocarcinoma of lower lip, buccal mucosa, mandible, tongue, floor, or palate. Positive nuclear and cytoplasmic labeling for DNMT1 occurs in all samples, positive nuclear labeling for DNMT3a occurs only in few neoplasms: 1 pleomorphic adenoma, 2 adenoid cystic carcinoma and 1 mucoepidermoid cases, immunohistochemical
CD4+, ranscript levels of DNA methyltransferases DNMT1, DNMT3A and DNMT3B in CD4+ T cells from patients with systemic lupus erythematosus, an autoimmune disease with CD4+ T cells with hypomethylated DNA. It is possible that patients are reacting indirectly to an underlying DNA hypomethylation status by increasing the mRNA levels of DNA methyltransferases when the disease is definitely active, overview
B lymphoblast cell line containing wild-type p53. The interaction between p53 and DNMT1 controls DNA methylation of the p16ink4A promoter that consequently reduces the level of the p16ink4A
B lymphoblast cell line with mutant p53. Mutant p53 loses its ability to suppress DNMT1 expression, and thus enhances methylation levels of the p16ink4A promoter and subsequently down-regulates p16ink4A protein
the somatic form of Dnmt1 is present in association with chromatin in MII-stage oocytes as well as in the nucleus throughout preimplantation development. At the early one-cell stage, somatic Dnmt1 is asymmetrically localized in the maternal pronuclei. Thereafter, somatic Dnmt1 is recruited to the paternal genome during pronuclear maturation. During the first two cell cycles after fertilization, Dnmt1s is exported from the nucleus in the G2 phase in a CRM1/exportin-dependent manner
