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…]

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…]
