Differential DNA Methylation Correlates with Differential Expression of Angiogenic Factors in Human Heart Failure
Epigenetic mechanisms such as microRNA and histone modification are crucially responsible for dysregulated gene expression in heart failure. In contrast, the role of DNA methylation, another well-characterized epigenetic mark, is unknown. In order to examine whether human cardiomyopathy of different etiologies are connected by a unifying pattern of DNA methylation pattern, we undertook profilin...
متن کاملDNA methylation abnormalities in congenital heart disease
Congenital heart defects represent the most common malformation at birth, occurring also in ∼50% of individuals with Down syndrome. Congenital heart defects are thought to have multifactorial etiology, but the main causes are largely unknown. We have explored the global methylation profile of fetal heart DNA in comparison to blood DNA from control subjects: an absolute correlation with the type...
متن کاملDNA 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...
متن کاملDNA methylation and healthy human aging
The process of aging results in a host of changes at the cellular and molecular levels, which include senescence, telomere shortening, and changes in gene expression. Epigenetic patterns also change over the lifespan, suggesting that epigenetic changes may constitute an important component of the aging process. The epigenetic mark that has been most highly studied is DNA methylation, the presen...
متن کاملThe role and importance of DNA methylation in spermatogenesis process
Background: DNA methylation is one of the epigenetic marks that are created by de novo DNA methylation and be maintained through cell division. This process is catalyzed by DNA methyltransferases. DNA methylation establishment in germ line is important, since they have the potential to regulate gene expression in offspring and improper DNA methylation patterns in germ lines has serious conseque...
