WebJun 21, 2012 · DNA methyltransferase 3A (DNMT3A) is one of two human de novo DNA methyltransferases essential for transcription regulation during cellular development and differentiation. There is increasing evidence that RNA plays a role in directing DNA methylation to specific genomic locations within mammalian cells. WebMethods: The correlation between miR-29b and DNMT3A/3B expression was evaluated by RT-qPCR, western blotting and immunohistochemical analysis. The functional roles of miR-29b and DNMT3A/3B were tested by anti-miRs and microRNA precursors. A luciferase reporter assay was employed to detect the direct binding of miR-29b to DNMT3A/3B 3' …
WebApr 7, 2024 · Disrupting the adult globin promoter alleviates promoter competition and reactivates fetal globin gene expression. Abstract The benign condition hereditary persistence of fetal hemoglobin (HPFH) is known to ameliorate symptoms of co-inherited β-hemoglobinopathies, such as sickle cell disease and β-thalassemia. WebA myriad of protein partners modulate the activity of the human DNA methyltransferase 3A (DNMT3A), whose interac- tions with these other proteins are frequently altered during oncogenesis. We show here that the tumor suppressor p53 decreases DNMT3A activity by forming a heterotetramer com- plex with DNMT3A.
