The people behind the papers – Jinjin Zhu & Justin Kumar

Posted by on April 9th, 2018

Cell fate commitment relies on both activation of appropriate genes and suppression of inappropriate ones. Polycomb group proteins are known to be crucial epigenetic silencers of developmental genes, but the manner by which they control fate in vivo, and the relative roles of different Polycomb proteins in silencing, have remained unclear. A new paper in Development[…]

In vivo profiling of chromatin accessibility with CATaDa

Posted by on March 13th, 2018

The following post is an introduction into the technnique described in our recent paper: Aughey, G.N., et al., CATaDa reveals global remodelling of chromatin accessibility during stem cell differentiation in vivo. Elife, 2018. 7.   Attempting to understand the biology of a complex organ, like the brain, comes with an array of technical challenges. Those[…]

Silencing transposons during epigenetic reprogramming

Posted by on November 8th, 2017

Molecules called endosiRNAs help us avoid genetic chaos, according to a new study from a team at the Babraham Institute. Much of the human genome contains pieces of DNA called transposons, a form of genetic parasite. When active, transposons can damage genes so it is important to keep them inactive. At a certain point early[…]

Older wombs linked to complications in pregnant mice

Posted by on September 6th, 2017

This article is recent news from the Babraham Institute in Cambridge, view the original post here and the Nature Communications research paper here. Deciding to start a family later in life could be about more than just the age of your eggs. A new study in mice suggests the age of a mother’s womb may[…]

The people behind the papers: Rute Tomaz & Véronique Azuara

Posted by on February 15th, 2017

Embryonic stem cells express genes necessary for self-renewal, and also ‘prime’ lineage-specific genes which stay silent until differentiation; the molecular players and pathways that govern the timely gene expression are still being delineated. Today’s paper comes from the most recent issue of Development and reveals a role for the histone demethylase Jmjd2c in gene activation in stem cell[…]

Postdoctoral position in chromatin and epigenetic control of Drosophila development

Posted by on June 30th, 2016

Stockholm University, Sweden, invites applications for one postdoctoral position in the laboratory of Professor Mattias Mannervik at the Department of Molecular Biosciences, The Wenner-Gren Institute (http://www.su.se/mbw). The position is scheduled to start as soon as possible.   Transcriptional coregulators are proteins that facilitate communication between transcription factors and the basal transcription apparatus, in part by[…]

Adventures in Studying Brain Sex Differences

Posted by on May 8th, 2015

by Peg McCarthy and Bridget Nugent The biological phenomenon of hormonally induced sexual differentiation of the brain has been an empirical topic of study for over 50 years1 but much remains to be discovered in terms of both mechanism and functional impact. In the McCarthy lab we exploit the many advantages of the laboratory rat[…]

A postdoctoral position is open in an INSERM laboratory (Marseille, France) Cardiac Developmental Biology

Posted by on June 24th, 2013

Our team focuses on epigenetic regulation of determination of cardiac cell lineages using stem cells and mouse embryos. The fellow will investigate how changes in the 3D chromatin configuration affect the development of the heart.  She/he will work with both wt mouse embryos (lineage tracing, micro-ChIP, 3C technologies, DNA microinjection) and from the second year[…]
