Combining RNA fluorescent in situ hybridization (FISH) with immunofluorescence (immuno-FISH) creates a technique that can be employed at the single cell level to detect the spatial dynamics of RNA localization with simultaneous insight into the localization of proteins, epigenetic modifications and other details which can be highlighted by immunofluorescence. X-chromosome inactivation is a para...

The term epigenetic modification denotes reversible traits of gene expression that do not include alterations to the DNA sequence. These epigenetic alterations are responsible for chromatin structure stability, genome integrity, modulation of tissue-specific gene expression, embryonic development, genomic imprinting and X-chromosome inactivation in females. Epigenetic changes include reversible...

DNA sequencing technology is one of the important tools in modern life science research, and with development technology, constantly changing. High-throughput known as second generation technology. Compared Sanger high-throughput has characteristics high throughput, fast speed low cost. In this paper, researcher briefly introduced emergence expounded application epigenetic research from aspects...

INTRODUCTION Epigenetic modification plays a critical role in regulating gene expression. To understand how epigenetic modification alters miRNA expression in monocyte-derived dendritic cells (moDCs) in different environments, we analyzed the connections between H3K4me3 and H3K27me3 modification and the expression of miRNAs in LPS- and TGF-β-conditioned moDCs. RESULTS In moDCs, H3K4me3 modifi...

Epigenetics can be defined as all the meiotically and mitotically inherited changes in gene expression that are not encoded in the DNA sequence itself. Epigenetic modifications of chromatin and DNA have been recognized as important permissive and suppressive factors in controlling the expressed genome via gene transcription. Two major epigenetic mechanisms are the posttranslational modification...

In recent years, the role of epigenetics in the development and treatment of cancer has gained interest and the effects of internal and external factors on the epigenetic profile are under investigation. The term “epigenetics” refers to modifications that influence phenotype without altering genotype. Epigenetic changes are potentially reversible but generally stably maintained during the cell ...

BACKGROUND The therapeutic use of multipotent stem cells depends on their differentiation potential, which has been shown to be variable for different populations. These differences are likely to be the result of key changes in their epigenetic profiles. METHODOLOGY/PRINCIPAL FINDINGS to address this issue, we have investigated the levels of epigenetic regulation in well characterized populat...

Background: Hepatocellular carcinoma (HCC), primary liver cancer, is a major health problem and the third most common cause of cancer-related deaths worldwide. Epigenetic modulations are essential for the maintenance of gene expression patterns in mammals. Disruption of these processes can lead to silenced gene and malignant cellular transformation. The current study was designed to compare the...

Epigenetic modifications of the chromatin structure are crucial for many biological processes and act on genes during the development and germination of seeds. The spatial distribution of 3 epigenetic markers, i.e. H4K5ac, H3K4me2 and H3K4me1 was investigated in 'matured,' 'dry,' 'imbibed" and 'germinating' embryos of a model grass, Brachypodium. Our results indicate that the patterns of epigen...
