What is Epigenetics technical articles are geared towards epigenetic research techniques, news, and trends in the field of epigenetics, written by scientists from universities and institutions including UCLA, Hofstra, NIH, Johns Hopkins, and more.
Explore in detail new epigenetic research techniques and tips for topics like next-generation sequencing (NGS) in epigenetics, m6A RNA methylation, CRISPR/Cas9 system epigenetic editing, chromatin immunoprecipitation (ChIP) protocol optimization, and single-cell epigenomics methods.

San Diego-based Illumina, Inc. doubles the sequencing output of its benchtop sequencer MiSeq to 15 gigabases (Gb) by increasing the number of sequencing reads to up to 25 million reads and overall read length to up to 2×300 base pairs. Subsequently, researchers can perform additional new applications on the MiSeq, including exome sequencing. Transcriptome applications such as mRNA sequencing can be supported now as well. Increased paired-end read lengths also improves the quality of genome assemblies, thereby advancing applications that [more…]
Currently, DNA methylation is one of the most broadly studied and well-characterized epigenetic modifications associated with gene silencing. The biological importance of 5-mC as a major epigenetic modification in phenotype and gene expression has been widely recognized. DNA hypomethylation is likely caused by methyl-deficiency due to a variety of environmental influences and has been proposed as a molecular marker in multiple biological processes such as cancer. The quantification of 5-mC content or global methylation in diseased or environmentally impacted cells [more…]
Robust and versatile technologies that enable optical modulation of transcription in the mammalian endogenous genome have been difficult to achieve for a while. To solve this problem, scientists at the Broad Institute of MIT and Harvard developed light-inducible transcriptional effectors (LITEs) — an optogenetic two-hybrid system integrating the TALE DNA-binding domain with a light-sensitive cryptochrome 2 protein and its partner CIB1 from the Arabidopsis thaliana plant. LITEs can be customized to target many endogenous genomic loci and can be quickly [more…]
Scientists from Broad Institute of MIT and Harvard report in-depth analysis of 42 whole-genome bisulfite sequencing data sets across 30 diverse human cell and tissue types. This study tries to answer when, where, and how many CpGs are involved in genomic regulation. Within a normal developmental context, the scientists observed dynamic regulation for only 21.8% of autosomal CpGs, most of which are situated away from transcription start sites. These dynamic CpGs co-localize with enhancers and transcription-factor-binding sites, allowing for identification [more…]
