چکیده
Purpose of review To provide guidance for investigators who are new to the field of DNA methylation analysis. Recent findings Epigenetics is the study of mitotically heritable alterations in gene expression potential that are not mediated by changes in DNA sequence. Recently, it has become clear that nutrition can affect epigenetic mechanisms, causing longterm changes in gene expression. This review focuses on methods for studying the epigenetic mechanism DNA methylation. Recent advances include improvement in highthroughput methods to obtain quantitative data on locusspecific DNA methylation and development of various approaches to study DNA methylation on a genome-wide scale. Summary No single method of DNA methylation analysis will be appropriate for every application. By understanding the type of information provided by, and the inherent potential for bias and artifact associated with, each method, investigators can select the method most appropriate for their specific research needs.

The 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...
متن کاملA convenient method to generate methylated and un-methylated control DNA in methylation studies
Methylated and un-methylated control DNA is an important part of DNA methylation studies. Although human and mouse DNA methylation control sets are commercially available, in case of methylation studies on other species such as animals, plants, and bacteria, control sets need to be prepared. In this paper a simple method of generating methylated and un-methylated control DNA is described. Whole...
متن کاملInvolvement of Cytosine DNA methylation in different developmental stages of Aeluropus littoralis
DNA methylation as epigenetic mark plays a key role in normal differential and developmental processes as well as in dynamic gene regulation at the genomic level. To assess DNA methylation pattern in different developmental stages of Aeluropus littoralis, methylation sensitive amplified polymorphism (MSAP) was used. Methylation and demethylation status at the CCGG recognition site were...
متن کاملO-37: Pseudomalignant Nature of Placenta during Normal and Pathological Gestation Is Regulated by Epigenetic Mechanisms which Can be Exploited To Design Non-Invasive Fetal Dna Markers
Background Placentation shares many analogues with the development of tumors such as rapid proliferation, invasiveness, gene expression profiles especially the expression of tumor suppressor genes, oncogenes and matrixmetallo proteinases (MMPs). Thus, a placenta has been described as a pseudomalignant tissue. However, placentation is tightly regulated and any deregulation of this pseudomalignan...
متن کاملP-13: Comparison of Sperm Quality, Oxidative Stress, DNA Fragmentation, Protamine Deficiency, and DNA Methylation in Varicocele and Fertile Individuals
s:1993:"Background: There are many approaches that gene expression is controlled in eukaryotes. DNA methylation is one of several epigenetic mechanisms that cells use to control gene expression and lock genes in the "off" position. In addition, sperm DNA damage can correlate with DNA methylation defect. There is evidence that sperm of infertile men contain more DNA damage than fertile men and t...
