UBF and chromatin structure at the rDNA locus (Tom Moss)

In this episode of the Epigenetics Podcast, we caught up with Professor Tom Moss from Université Laval in Québec City, Canada to talk about his work on the chromatin structure and dynamics at ribosomal RNA genes.   Dr. Tom Moss has been a member of the Department of Molecular Biology, Medical Biochemistry, and Pathology at the Laval University School of Medicine since he was recruited from the University of Portsmouth in the United Kingdom in 1986. Since then he focused on the ribosomal transcription factor Upstream Binding Factor (UBF) and how it regulates the chromatin structure at ribosomal RNA genes (rDNA).   UBF binds to the rDNA as a dimer where it leads to six in-phase bends and induces the formation of the ribosomal enhanceosome. This enhanceosome is required for the initial step in formation of an RNA polymerase I initiation complex, and therefore plays an important role in regulating the expression of ribosomal RNA genes.   In this Interview, we discuss the function of UBF on the rDNA, how UBF impacts the chromatin landscape at rRNA genes, the role of DNA methylation in this process, and how UBF influences the structure of the nucleolus.     References D.

In this episode of the Epigenetics Podcast, we caught up with Dr. Andrew Pospisilik from the Van Andel Institute in Grand Rapids, Michigan to talk about his work on the epigenetic origins of heterogeneity and disease. Dr. Andrew Pospisilik worked at the Max-Planck Institute of Immunobiology and Epigenetics in Freiburg for 8 years and in 2018 he joined the Van Andel Institute as the director of its Center for Epigenetics. At the Van Andel Institute his research focuses on diabetes, neurodegenerative diseases, cancer, and obesity. The goal of the Pospisilik laboratory is to better understand epigenetic mechanisms of these diseases and the roles of epigenetics in disease susceptibility and heterogeneity.   These areas of medicine are among the most important public health challenges, with the latest estimates suggesting that they impact more than 1 billion people worldwide. Although these diverse conditions are all very different, they are now thought to be caused, at least partially, from alterations in the epigenetic mechanisms that regulate gene expression and metabolism. This interview covers recent work from the Pospisilik lab on the epigenetics of these complex diseases.    References https://pospisiliklab.vai.org/ J. Andrew Pospisilik, Daniel Schramek, … Josef M.

In this episode of the Epigenetics Podcast, we caught up with Karol Bomsztyk M.D. and Tom Matula, Ph.D. from the University of Washington and Matchstick Technologies, to talk about their work on DNA and chromatin sonication. During his career, Karol's research has focused on improving ChIP protocols to make them faster, easier and higher throughput. First, to make ChIP assays faster, Karol and his lab developed "Fast-ChIP". More recently, he adjusted this protocol to improve throughput and "Matrix-ChIP" was born. Tom is an expert in the field of ultrasound and cavitation and the Director of the Center for Industrial and Medical Ultrasound at the University of Washington. To further improve and speed up the 96-well "Matrix-ChIP" protocol, Karol and Tom teamed up to found Matchstick Technologies and develop a sonication device that would be able to processes each and every well of a 96-well microplate consistently and quickly. The result of this cooperation is the PIXUL Multi-Sample Sonicator that is now available for order from Active Motif. PIXUL is an ultrasound-based sample preparation platform that was designed completely from the ground up to provide researchers with an easy-to-use tool that is simple to set up, simple to use, and generates consistent results day in and day out. No other sample preparation platform out there can match the power and convenience of PIXUL. PIXUL was conceived by an epigenetics researcher, and designed and built by ultrasound engineers to take the guesswork out of sample preparation. With PIXUL, sample preparation is no longer an art form, but instead a simple and predictable part of experiments that work every single time. This interview goes into the mechanism behind sonication-based shearing of DNA and chromatin and highlights how PIXUL is different from existing sonication instruments.   References http://activemotif.com/PIXUL Karol Bomsztyk Tom Matula Innovation Imperative: New Device Speeds Disease Biomarker Search    Contact Active Motif on Twitter Epigenetics Podcast on Twitter Active Motif on Linked-In Active Motif on Facebook eMail: podcast@activemotif.com

In this episode of the Epigenetics Podcast, we sat down with Marcus Buschbeck, Group Leader at the Josep Carreras Leukaemia Research Institute in Barcelona, to talk about his work on the histone variant macroH2A, its role in metabolism and how it contributes to the regulation of chromatin structure.   Histone variants equip chromatin with unique properties and show a specific genomic distribution. The histone variant macroH2A is unique in having a tripartite structure consisting of a N-terminal histone-fold, an intrinsically unstructured linker domain and a C-terminal macro domain. Recent discoveries show that macroH2A proteins have a major role in the nuclear organization which has the potential to explain how these proteins can act as tumor suppressors, promoters of differentiation and barriers to somatic cell reprogramming.   We discuss these topics, the mission of the Josep Carreras Leukaemia Research Institute, and much more in this episode.    References http://www.carrerasresearch.org/Buschbeck_Marcus Marcus Buschbeck, Iris Uribesalgo, … Luciano Di Croce (2009) The histone variant macroH2A is an epigenetic regulator of key developmental genes (Nature Structural & Molecular Biology) DOI: 10.1038/nsmb.1665  Julien Douet, David Corujo, … Marcus Buschbeck (2017) MacroH2A histone variants maintain nuclear organization and heterochromatin architecture (Journal of Cell Science) DOI: 10.1242/jcs.199216  Melanija Posavec Marjanović, Sarah Hurtado-Bagès, … Marcus Buschbeck (2017) MacroH2A1.1 regulates mitochondrial respiration by limiting nuclear NAD+ consumption (Nature Structural & Molecular Biology) DOI: 10.1038/nsmb.3481 Oriana Lo Re, Julien Douet, … Manlio Vinciguerra (2018) Histone variant macroH2A1 rewires carbohydrate and lipid metabolism of hepatocellular carcinoma cells towards cancer stem cells (Epigenetics) DOI: 10.1080/15592294.2018.1514239 Contact https://twitter.com/activemotif https://twitter.com/epigenetics_pod https://www.linkedin.com/company-beta/35651/ https://www.facebook.com/ActiveMotifInc/ podcast@activemotif.com

In this Episode of the Epigenetics Podcast our guest Ana Pombo from the Max-Delbrück-Center in Berlin provides insight in her work on the interplay between gene regulation and genome architecture. To do so she and her team use different state of the art methods, including cryo-sectioning to unravel this regulatory network. In 2006, they proposed the Interchromatin Network Model of chromosome organization which postulates that chromosome folding is driven by contacts between different genomic regions and between chromatin and nuclear landmarks, such as the nuclear lamina. And later on they used polymer physics modeling to study those mechanisms, which lead to the development of the Strings & Binders Switch (SBS) model. And this is just a glimpse of the topics that are discussed in this Episode.   References Miguel R.

Dosage compensation is an essential process to regulate the gene expression of the X-chromosome in female and male flies. Thereby the mechanism of regulation in humans and in drosophila is different. In humans one X-chromosome is randomly shut down in females compared to men, whereas in drosophila equilibrium is achieved by overexpression of the single X-chromosome in males. In this Episode our guest Dr. Asifa Akhtar provides information on her work on dosage compensation in drosophila melanogaster and how the MSL-complex, the Histone-acetyltransferase MOF work together in this process. Furthermore, she also talks about potential functions of those Proteins in the human system.   References  Jan Kadlec, Erinc Hallacli, … Asifa Akhtar (2011) Structural basis for MOF and MSL3 recruitment into the dosage compensation complex by MSL1 (Nature Structural & Molecular Biology) DOI: 10.1038/nsmb.1960  Thomas Conrad, Florence M.G.

In recent years it has become more and more evident, that genome folding and chromatin packaging into the nucleus plays a pivotal role in the regulation of gene expression. In this Episode of our Podcast our host Dr. Stefan Dillinger spoke with Professor Wendy Bickmore about her work on the spatial organization of the human genome. Prof. Bickmore and her team mainly use visual methods like fluorescence in situ hybridisation (FISH) to study the organization of chromosomes in human and murine cells and how they contribute to transcriptional regulation and how this organization changes during ageing, development or disease.
