DNA Methylation in T-Cell Development and Differentiation

DNA Methylation and Its Role in the Development of Leukemia

Epigenetic changes play an essential role in cancer pathogenesis. It has been established by next-generation sequencing that more than 50% of the human cancers carry mutations in mechanisms involved in the organization of the chromatin and epigenetic regulations. DNA methylation is among the most common epigenetic changes in leukemia. In contrast to DNA mutations which are passively inherited f...

DNA methylation and differentiation.

The methylation of specific cytosine residues in DNA has been implicated in regulating gene expression and facilitating functional specialization of cellular phenotypes. Generally, the demethylation of certain CpG sites correlates with transcriptional activation of genes. 5-Azacytidine is an inhibitor of DNA methylation and has been widely used as a potent activator of suppressed genetic inform...

The Impression of Histone Modification and DNA Methylation in Gastric Cancer Development: Molecular Mechanism Approach

The epigenetic alterations like histone modifications , DNA methylation and others remarkable categories  including nucleosome remodeling and RNA mediated targeting have been strongly investigated  recently .In this way , beside the notable importance of DNA methylation ,the histone modifications are the most important issues in the  tumorogenesis and cancer progression. Moreover...

DNA Methylation Dynamics of Human Hematopoietic Stem Cell Differentiation

Hematopoietic stem cells give rise to all blood cells in a differentiation process that involves widespread epigenome remodeling. Here we present genome-wide reference maps of the associated DNA methylation dynamics. We used a meta-epigenomic approach that combines DNA methylation profiles across many small pools of cells and performed single-cell methylome sequencing to assess cell-to-cell het...
