CHD4 in the DNA-damage response and cell cycle progression: not so NuRDy now — Heinrich lab (2013)

Review by O'Shaughnessy and Hendrich that describes that CHD4 is a defining member of the NuRD complex, but evidence is accumulating that CHD4 also plays important NuRD-independent roles in the DNA-damage response and cell cycle progression, as well as in transcriptional regulation.

A dual role for Hdac1: oncosuppressor in tumorigenesis, oncogene in tumor maintenance—Minucci and collaborator labs (2013)

In mice, Hdac1 is shown to act distinctly depending on the tumor stage: it works as an oncosuppressor during initiation but as an oncogene during maintenance.

Epigenetic epistatic interactions constrain the evolution of gene expression — Lehner lab (2013)

Here, Park and Lehner propose that the tight regulation of epistatic interaction network hubs is critical for maintaining a robust phenotype.

Directly from the source: endogenous preparations of molecular machines — Schaffitzel lab (2013)

A timely review from the Schaffitzel lab about recent accomplishments and limitations of purifying large, endogenous macromolecular machines.

Transcriptional repressors: multifaceted regulators of gene expression — Heinrich lab (2013)

Brian Hendrich and coworkers review the evidence for the presence of repressors at actively transcribed regions and assess what roles they might be playing. They propose that the modulation of expression levels by chromatin-modifying, co-repressor complexes provides transcriptional fine-tuning that drives development.

The architecture of human general transcription factor TFIID core complex — Schaffitzel and Berger labs (2013)

Until now, the inability to produce enough high-quality recombinant complex has hindered scientists from obtaining the structural information necessary to fully understand the molecular function of the general transcription factor TFIID. Several groups led by the Berger team have now elucidated a high-resolution structure (11.6Å) for the core TFIID complex, a 650 kDa complex containing ten protein subunits. Their findings, published in Nature, now reveal the architecture of the core TFIID and answer several long-standing questions about TFIID.

RyBP and Cbx7 define specific biological functions of Polycomb complexes in mouse embryonic stem cells — Di Croce lab (2013)

Lluis Morey, Luigi Aloia, Luciano Di Croce, and coworkers analyzed 2.64 billion DNA nucleotides of DNA from mouse embryonic stem cells to determine which regions are controlled by PRC1-RYBP as compared to PRC1-CBX7.

Stoichiometry of chromatin-associated protein complexes revealed by label-free quantitative mass spectrometry-based proteomics – Vermeulen lab (2012)

In this manuscript from the Vermeulen lab, the stoichiometry of the epigenetic regulator complexes of MBD3/NuRD and PRC2 were determined using the novel iBAC system of label-free, quantitative mass spectrometry–based proteomics.
