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...

for a long time, scientists have tried to describe disorders just by genetic or environmental factors. however, the role of epigenetics in human diseases has been considered from a half of century ago. in the last decade, this subject has attracted many interests, especially in complicated disorders such as behavior plasticity, memory, cancer, autoimmune disease, and addiction as well as neurod...

intoduction: acute myeloid leukemia (aml) is a heterogeneous group of hematologic malignancies with abundant changeability in the pathogenesis. dna methylation of cpg islands within the promoters of specific genes may play roles in tumor initiation and progression. secreted frizzled-related proteins (sfrps) are negative regulator of the wnt signaling pathway. in the present study, we examined t...

Coronary artery disease (CAD) is a common health problem in Iranian population. ATP binding cassette transporter A1 (ABCA1) plays central role in the efflux of the cholesterol from peripheral tissues back to liver. Inactivation of ABCA1 by epigenetic change such as DNA methylation may contribute to the development of CAD. The present study investigated the association between promoter DNA methy...

objective: a recent field of research in epigenetics is dna methylation which involves the cpg island in the genome that subsequently controls transcription and translation of targeted genes. in the hepatitis b virus (hbv) genome, there are three cpg islands which tend to be methylated. the aim of the current study is to determine the methylation pattern of the hbv x gene in chronically infecte...

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...

Objective (s): Titanium dioxide nanoparticles (TiO2 NPs) have been recognized as biologically inert material and have been used in a multitude of applications. Nevertheless, the negative impact on the human health is not yet well understood. Aim of the work: The study attempted to evaluate the epigenetic changes of the genome, in the form of DNA methylation in liver tissue samples, resulting fr...
