چکیده

This perspective on Candiloro and Dobrovic (beginning on p. 862 in this issue of the journal) highlights the interplay between epigenetic aberrations and underlying DNA sequence changes and illustrates how these alterations may predispose individuals to cancer. Candiloro and Dobrovic clearly show that particular genotypes of the MGMT gene are associated with its methylation in healthy individuals. Aberrant MGMT methylation may identify individuals who could be targeted for cancer screening and chemoprevention strategies.

A 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...

P-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...

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...

P-128: The Effect of DNA Methyl Transferase1 Inhibitor (RG108) on DNA Methylation Pattern of Cloned Mouse Embryos

Background: In somatic cell nuclear transfer (SCNT) method of cloning, transferred nucleus should be dedifferentiated from differentiated state to embryonic state. Molecular analysis showed that the reprogramming in the transferred nucleus was incomplete and cloned embryos have epigenetic abnormalities such as high DNA methylations levels. Since methylation in pre-implantation embryos has a cri...

Involvement 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...
