Targeting Noncoding RNAs in Disease: Challenges and Opportunities

September 13, 2013 WhatIsEpigenetics

Noncoding RNAs make up the majority of transcribed RNA and have a wide range of functions in cellular and developmental processes. Consequently, they are also implicated in the development and pathophysiology of many diseases and represent potential targets for therapeutic intervention. Scientists found that effective in vivo inhibition (or silencing) of microRNA, one class of noncoding RNA, has enabled to make groundbreaking discoveries about the contribution of these short regulating RNAs to some of the major human diseases, such as [more…]

Research in Epigenetics Experiencing Exponential Growth

August 26, 2013 WhatIsEpigenetics

Publication growth in epigenetic-related research attests to the exponential expansion of this field since 2000 according to GENRports (GENReports: Market & Tech Analysis, Produced by Enal Razvi). The yearly published articles related to epigenetics are sharply increased from about 1000 in 2000 to more than 11,000 in 2012 (See Figure: “Growth of Epigenetics-Focused Publications in PubMed”). Around 50% of the research is focused on DNA methylation and 25% is for non-coding RNA studies, while another 25% is related to histone [more…]

Illumina Doubles Output of Benchtop Sequencer MiSeq to 15 Gb

August 26, 2013 WhatIsEpigenetics

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…]

System for Optical Control of Mammalian Endogenous Transcription and Epigenetic States

August 26, 2013 WhatIsEpigenetics

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…]

In-Depth Analysis of 42 Whole-Genome Bisulfite Sequencing Data Carried Out by Broad Institute

August 24, 2013 WhatIsEpigenetics

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…]
