Chromatin Structure and Dynamics at Ribosomal RNA Genes (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.
Epigenetic Origins Of Heterogeneity And Disease (Andrew Pospisilik)
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 for 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 podcast interview covers recent work from the Pospisilik lab on the epigenetics of these complex diseases.
PIXUL: On the Leading Edge of Chromatin Shearing (Karol Bomsztyk and Tom Matula)
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 physics 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 and co-founded Matchstick Technologies to 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 works 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.
Influence of Histone Variants on Chromatin Structure and Metabolism (Marcus Buschbeck)
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 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.

The Interchromatin Network Model (Ana Pombo)
There are many levels of control that contribute to regulating the levels of gene expression. One major mechanism of gene regulation involves organization of the genome within the nucleus. In this episode of the Epigenetics Podcast, our guest Professor Ana Pombo from the Max-Delbrück-Center in Berlin provides insight into her work on the interplay between gene regulation and genome architecture.
Dr. Pombo and her team use different state-of-the-art methods in their research, 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 chromatin and nuclear landmarks, such as the nuclear lamina. They also used polymer physics modeling to study those mechanisms, which lead to the development of the "Strings and Binders Switch" model of chromatin organization.
Listen to the podcast episode to learn more about this fascinating topic.
Dosage Compensation in Drosophila (Asifa Akhtar)
For many organisms, from fruit flies to humans, sex is determined by the number of X chromosomes. Females often have two copies of the X and males have one, creating an imbalance in the number of X chromosome genes present in each sex. Different organisms have evolved different strategies for how to cope with this imbalance. For example, in humans, one of the two X chromosomes in every female cell is randomly inactivated, leaving both males and females with one active X chromosome each. However, in Drosophila, the balance is achieved by males overexpressing the genes on their single X chromosome two-fold to bring up the levels of gene expression to match expression from the two X chromosomes in females. Essentially the same end result is achieved in both humans and Drosophila, balanced levels of X chromosome transcription in both males and females, but using two extremely different mechanisms.
In this episode, our guest Dr. Asifa Akhtar, Senior Group Leader and Director at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg, Germany, discussed her lab's recent work on dosage compensation in Drosophila melanogaster. Dr. Akhtar talked about how the MSL complex, and the histone acetyltransferase MOF in particular, contributes to the regulation of the dosage compensation process. Furthermore, she also talked about some potential functions of the conserved MSL proteins in humans and how they are similar to and different from their fruit fly counterparts.

Diabetes and Epigenetics (Jean-Sébastien Annicotte)
Type 2 Diabetes (T2D) is a chronic metabolic disease that is caused by the failure of beta-cells in the pancreas and insulin resistance in peripheral tissue, and is characterized by high glucose levels in the blood. 382 million people suffer from diabetes worldwide, which makes up >8% of the global population.
Due to this high proportion of people affected, it is of high interest to find a cure for this disease and tremendous efforts have been made on deciphering epigenetic regulations that control metabolic tissue function.
For several years, the research team led by Dr. Jean-Sebastien Annicotte have dissected the molecular links between insulin producing cells, insulin target tissues, and T2D/obesity development. Their research has specifically been focused on the role of cell cycle regulators and their transcriptional co-regulators in the control of metabolic homeostasis, T2D and obesity.
In this podcast episode, we caught up with Dr. Jean-Sebastien Annicotte to discuss his views on type 2 diabetes and the roles of epigenetic mechanisms in regulating this disease.
