The Role of Histone Dopaminylation and Serotinylation in Neuronal Plasticity (Ian Maze)
In this episode of the Epigenetics Podcast, we caught up with Ian Maze from Ichan School of Medicine at Mount Sinai and a Howard Hughes Medical Institute (HHMI) Investigator to talk about his work on the role of histone dopaminylation and serotinylation in neuronal plasticity.
The Maze group focuses on understanding the complex interplay between chromatin regulatory mechanisms in brain and neuronal plasticity. The lab places an emphasis on psychiatric disorders associated with monoaminergic (e.g., serotonin, dopamine, etc.) dysfunction, such as major depressive disorder and drug addiction. In particular the Maze team has investigated cocaine addiction and its effect on chromatin by serotonylation and dopaminylation of Histone H3 Tails.
The Role of Blimp-1 in Immune-Cell Differentiation (Erna Magnúsdóttir)
In this episode of the Epigenetics Podcast, we caught up with Erna Magnúsdóttir from the University of Iceland to talk about her work on the role of Blimp-1 in immune-cell differentiation.
The Magnúsdóttir Lab is interested in how the mammalian genome is interpreted in a context dependent manner, leading to different cellular states, by using mouse primordial germ cells as well as mouse and human B-cells as model systems. More specifically, the team is interested in the Transcription Factor Blimp-1 and its effect on immune cell differentiation. Next to its function in immune cells, Blimp-1 also plays a role in Waldenström’s macroglobulinemia. The lab hopes to reveal the intricacies in disease progression and alteration in cellular states to increasingly aggressive tumor behavior.
Multimodal Characterization of Cellular Identity | CITE-Seq and Beyond (Peter Smibert, VP of 10X Genomics)
In this episode of the Epigenetics Podcast, we speak with Peter Smibert, Vice President of Biology at 10X Genomics to talk about an exciting new method in Multimodal Characterization of Cellular Identity using Barcoding.
During his time at the New York Genome Center, Peter Smibert was instrumental in the development of a new method called "Cellular Indexing of Transcriptomes and Epitopes by Sequencing" short CITE-Seq. This method enables the characterization of a cell's transcriptome, while at the same time, also allows the characterization of the cell's protein surface markers - at the single cell level. In CITE-Seq, sequencing adapters are coupled to antibodies that recognize surface proteins, which can then be detected by sequencing.
Further advancements of the CITE-Seq method led to the launch of BioLegend’s TOTAL-Seq and the integration of scATAC-Seq into the workflow. With the integration of scATAC-Seq in the CITE-Seq protocol, it is now possible to characterize single-cells along the path of the central dogma of biology, this is why the method called DOGMA-Seq.
The Effect of Mechanotransduction on Chromatin Structure and Transcription in Stem Cells (Sara Wickström)
In this episode of the Epigenetics Podcast, we caught up with Sara Wickström, Director at the Max Planck Institute for Molecular Biomedicine in Münster, to talk about her work on the effect of mechanotransduction on chromatin structure and transcription in stem cells.
Sara Wickström and her team focus on the stem cell niche and how that niche affects stem cell function. In order to study the native niche and to even be able to manipulate it, the Wickström Lab was able to develop a ex vivo culture system, allowing systematic identification of factors driving stem cell dynamics and plasticity.
Stem cells in the stem cell niche are exposed to external stimuli such as physical forces which control their growth, fate and self renewal. Recent work in the Wickström lab showed how mechanical signals influence transcriptional regulation, chromatin organization, and nuclear architecture and how this affects aging or lineage commitment. In this Episode we also discuss how chromatin can act as a sensor of mechanical signals taking advantage of the different physical properties of eu- and heterochromatin.
Single-Cell Technologies using Microfluidics (Ben Hindson, CSO of 10x Genomics)
In this episode of the Epigenetics Podcast, we caught up with Ben Hindson, Chief Scientific Officer at 10X Genomics, to talk about single-cell technologies using microfluidics.
Epigenetics has moved well past a simple understanding of a single epigenetic layer of control at genomic regions of interest, thanks to advances in many techniques and the application of “multiomics”. We can now analyze genome-wide histone modification patterns, transcription factor binding profiles, chromatin accessibility profiles, three-dimensional chromosomal conformation, and DNA methylation dynamics combined with transcriptomic analyses and associated analytical platforms.
Bulk Assays, like ATAC-Seq or ChIP, despite all their advantages, do not provide information about the chromatin states of individual subpopulations of cells within a sample. To identify chromatin features in heterogeneous populations, such as blood, pancreas, and brain, those analysis need to be performed at a single-cell level. 10X Genomics has been at the forefront of the movement into the single cell space and in this Episode we discuss this work with Ben Hindson, CSO of 10X genomics.
Epigenome-based Precision Medicine (Eleni Tomazou)
In this episode of the Epigenetics Podcast, we caught up with Eleni Tomazou from St. Anna Children's Cancer Research Institute in Vienna to talk about her work on Epigenome-based precision medicine.
The Tomazou lab studies Ewing sarcoma and the effects of Epigenetic factors on this disease. Ewing sarcoma is a type of cancer that affects bone and soft tissue of children and young adults, with a peak incidence at the age of 15. Ewing sarcoma is among the pediatric cancer types with the lowest survival rates and the development of novel therapies was obstructed by the limited understanding of the mechanisms behind the disease.
Work done in Eleni Tomazou's group identified an epigenetic signature of Ewing sarcoma which, ultimately, lead to the possibility to diagnose Ewing sarcoma from liquid biopsies. The team is now looking to find actionable targets like enhancers to develop therapies, finding biomarkers to enable disease monitoring, and to further characterize these tumors to decipher intra-tumor epigenetic heterogeneity and characterize the developmental stage of the cell of origin.
Epigenetics and Epitranscriptomics in Cancer (Manel Esteller)
In this episode of the Epigenetics Podcast, we caught up with Manel Esteller, Director of the Josep Carreras Leukemia Research Institute to talk about his work on Epigenetics and Epitranscriptomics in Cancer.
The focus of Manel Esteller's research career and the focus of his current team is to characterize the epigenome and epitranscriptome of cancer cells in comparison to healthy cells, and their interplay. Ultimately, their goal is to use this knowledge to develop new therapies for cancer. Key achievements from the Esteller lab began with the discovery of the first miRNA that undergoes specific cancer-methylation associated silencing. The team further identified many more miRNAs that also play a role in cancer. Next to miRNAs, Manel Esteller studied the influence of lncRNAs, enhancers and DNA methylation on cancer development and progression, insights that may be used to develop cancer biomarkers and potential treatments.
Enhancer-Promoter Interactions During Development (Yad Ghavi-Helm)
In this episode of the Epigenetics Podcast, we caught up with Yad Ghavi-Helm from the Institut de Génomique Functionnelle de Lyon to talk about her work on enhancer-promoter interactions during development.
The Laboratory of Yad Ghavi-Helm focuses on how developmental genes are regulated by enhancers. Their work shows that developmental genes are often regulated by more than one enhancer and that those enhancers can often be located many kilobases away on the linear chromosome. Furthermore, their research also indicates that the interactions between promoters and their respective enhancers are usually established before the expression of the target gene is switched on, and that those interactions are generally stable during embryogenesis. In addition, those stable interactions seem to coincide with paused RNA Pol II being located at those promoters before gene activation.
The Effect of Vitamin D on the Epigenome (Folami Ideraabdullah)
In this episode of the Epigenetics Podcast, we caught up with Folami Ideraabdullah from the University of North Carolina at Chapel Hill to talk about her work on the environmental modulation of the epigenome during development.
The lab of Folami Ideraabdullah focuses on studying how environmental factors modulate the epigenome. In particular the team investigates how Vitamin D levels influence epigenetic processes and, hence, the susceptibility for diseases like adipositas. Folami Ideraabdullah started with a genome-wide screen of DNA Methylation patterns that are observed after Vitamin D depletion. This work was then followed up by investigating the impact of Vitamin D depletion on mouse sperm DNA methylation.
H3K4me3, SET Proteins, Isw1, and their Role in Transcription (Jane Mellor)
In this episode of the Epigenetics Podcast, we caught up with Jane Mellor from the University of Oxford to talk about her work on H3K4me3, SET proteins, Isw1 and their role in transcription.
Since the beginning of the century, Jane Mellor and her team have focused on H3K4 trimethylation and the factors that influence this mark. They discovered that H3K4me3 is an almost universal mark of the first nucleosome in every transcribed unit and all organisms. She could subsequently, together with the Tony Kouzarides lab, identify SetD1, the enzyme that is responsible for writing this modification. Later on, the team characterized Isw1, a chromatin remodeler which “reads” H3K4me3. More recently the lab focuses on how the polymerase transcribes throughout the first nucleosomes of the transcribed region at the +2 nucleosome, with the help of Spt4.
The Role of DNA Methylation in Epilepsy (Katja Kobow)
In this episode of the Epigenetics Podcast, we caught up with Katja Kobow from the Universitätsklinikum Erlangen to talk about her work on the role of DNA methylation in Epilepsy.
Katja Kobow started studying the role of Epigenetics in Epilepsy by doing a genome wide Bisulfite-Sequencing screen that revealed a typical DNA methylation signature of epileptic patients versus healthy controls. After these initial results in human patient samples, she switched to an animal model to investigate this further. Now the focus of the Kobow Lab is to look for the same DNA methylation signature in blood samples, using this as a basis for the development of a potential prognostic marker for Epilepsy.
MacroH2A Function in Development and Disease (Emily Bernstein)
In this episode of the Epigenetics Podcast, we caught up with Emily Bernstein from Icahn School of Medicine at Mount Sinai to talk about her work on MacroH2A function and the role of Polycomb proteins in its epigenetic regulation, and how this affects stem cell development and disease.
The Bernstein Lab focuses on histone variants, in particular the H2A variant macroH2A. Chromatin architecture is influenced by the composition of the nucleosome and, hence, exchanging the core histones for histone variants can have a major impact on chromatin structure. MacroH2A variants are the most unique histone variants due to a 30kDa non-histone domain (macro domain) at their C-termini. This macro domain likely confers important functions to macroH2A variants, which have important regulatory roles in the cell. Among other things, the Bernstein Lab has shown that macroH2A is enriched at a critical set of Utx target genes whose expression is critical for the early stages of induced pluripotency, and that macroH2A plays a role as a barrier to tumorigenesis.
Spatio-Temporal Alterations in Chromosome Dynamics (Jane Skok)
In this episode of the Epigenetics Podcast, we caught up with Jane Skok from New York University School of Medicine to talk about her work on spatio-temporal alterations in chromosome dynamics.
Studies demonstrating that nuclear organization and long-range chromatin interactions play essential roles in gene regulation have been the focus of the Skok Lab, where the team has played a leading role. Their initial studies focused on lymphocyte development and the control of V(D)J recombination, a key part of generating the diverse repertoire of B-cell antibodies and T-cell receptors. The Skok Lab was among the first to demonstrate the possibility of chromatin forming dynamic loops which lead to the formation of reversible intra-locus loops in the immunoglobulin and T-cell receptor loci and to a profound impact on the ability of B and T cells to generate receptor diversity.
Chromatin Organization During Development and Disease (Marieke Oudelaar)
In this episode of the Epigenetics Podcast, we caught up with Marieke Oudelaar from the Max Planck Institute for Biophysical Chemistry to talk about her work on chromatin organization during development and disease.
Marieke Oudelaar and her team focus on on developing high-resolution Chromosome Conformation Capture (3C) based techniques, like low-input Capture-C, Tri-C, and Tiled-C. Those techniques are then used in combination with other genomic techniques, genetic perturbations, and computational approaches to investigate the 3D structure of chromatin in development and disease. The team focused on the interplay between genome organisation and regulation during mammalian differentiation, and how perturbations in these processes contribute to human disease, including cancer.
Enhancers and Chromatin Remodeling in Mammary Gland Development (Camila dos Santos)
In this episode of the Epigenetics Podcast, we caught up with Camila dos Santos from Cold Spring Harbor Laboratories to talk about her work on enhancers and chromatin remodeling in mammary gland development.
The lab of Camila dos Santos focuses on epigenetic regulation of normal and malignant mammary gland development. After puberty, the next significant phase in mammary gland development occurs in pregnancy, including changes in cellular function, and tissue reorganization. A different and as significant change in mammary glands occurs in the development breast cancer.
Camila dos Santos and her lab were recently able to show that the reaction of mammary glands to a second pregnancy is different than to a first one, which is accompanied by changes in the DNA methylome of the cells. Furthermore, the lab studies the connection of pregnancy-induced epigenetic changes of chromatin and the risk of cancer development.
The Role of SMCHD1 in Development and Disease (Marnie Blewitt)
In this episode of the Epigenetics Podcast, we caught up with Marnie Blewitt from the Walter and Eliza Hall Institute of Medical Research to talk about her work on the role of SMCHD1 in Development and Disease.
The Laboratory of Marnie Blewitt focuses finding inhibitors or activators for the epigenetic regulator SMCHD1. Marnie Blewitt identified and characterized this protein during her PhD and the findings were published in 2008 in Nature Genetics. Since then, she and her team were able to investigate the function of this protein further. By doing so, they showed the involvement of SMCHD1 in cancer and several other diseases. Currently the lab is screening for small molecules that can act as inhibitors or activators of SMCHD1 the former as potential treatments for facioscapulohumeral muscular dystrophy, the latter for Prader Willi and Schaaf-Yang syndromes, both of which have no current targeted treatments.
Single-Molecule Imaging of the Epigenome (Efrat Shema)
In this episode of the Epigenetics Podcast, we caught up with Efrat Shema from the Weizmann Institute of Science to talk about her work on Single Molecule Imaging of chromatin, and the analysis of nucleosomes circulating in plasma.
In ChIP-Seq experiments the peak you get as a read out represents an average over, most often, millions of cells. Furthermore, one often does not know if that peak represents one or more than one nucleosome. If you then want to study multiple marks at the same time, the question remains: do those modifications occur at the same time, in the same cell?
The Laboratory of Efrat Shema works on answering those questions by developing methods to study the modification patterns on single nucleosomes with single molecule imaging. With that it is possible to study single nucleosomes in a high throughout manner to identify the modifications they are decorated with. A subsequent sequencing step makes it possible to identify the genomic location of that nucleosome.
Heterochromatin Protein 1 and its Influence on the Structure of Chromatin (Serena Sanulli)
In this episode of the Epigenetics Podcast, we caught up with Serena Sanulli from Stanford University to talk about her work on Heterochromatin Protein 1 (HP1), the structure of chromatin on the atomic-scale and the meso-scale, and phase separation.
The Laboratory of Serena Sanulli is interested in finding connections between changes that happen on the nucleosomal level and the resulting impact on chromatin conformation on the meso-scale. They combine methods like NMR and Hydrogen-Deuterium Exchange-MS with Cell Biology and Genetics. This enables them to dissect how cells use the diverse biophysical properties of chromatin to regulate gene expression across length and time scales.
A second focus of the lab is HP1, which interacts with the nucleosome and changes its conformation, enabling the compaction of the genome into heterochromatin, effectively silencing genes in that region. A high concentration of HP1 leads to the phenomenon of phase separation in the nucleus, which the Sanulli lab is now investigating.
The Effects of Early Life Stress on Mammalian Development (Catherine J. Peña)
In this episode of the Epigenetics Podcast, we caught up with Catherine Jensen Peña from Princeton University to talk about her work on early life stress and its effects on behavior.
The Peña lab focuses on how early life experiences are encoded and maintained into adulthood, with a long-lasting impact on behavior. Recent work shows that child maltreatment and other forms of early life stress increase the lifetime risk of depression and other mood, anxiety, and drug disorders by 2-4 fold. The Peña lab uses genome wide approaches to investigate key brain regions with a two-hit stress model.
Using RNA-Seq, the Peña Lab has shown that depression-like gene expression patterns are programmed by early life stress, similar to observations in mice exhibiting depression-like behavior after adult stress and are visible even before behavioral changes. Furthermore, latent and unique transcriptional responses to adult stress among a subset of genes is programmed by early life stress. The role of chromatin modifications in regulating these processes are investigated using state of the art technologies like Mod-Spec or ATAC-Seq.
Targeting COMPASS to Cure Childhood Leukemia (Ali Shilatifard)
In this episode of the Epigenetics Podcast, we caught up with Ali Shilatifard from Northwestern University to talk about his work on targeting COMPASS to cure childhood leukemia.
The Shilatifard Lab studies childhood leukemia and how it can potentially be treated using epigenetic targets. The team focuses on is SET1/COMPASS, a histone H3 lysine4 methylase. Ali Shilatifard was able to purify and identify its activity, with results published in 2001 in PNAS. This protein complex is conserved from yeast to drosophila to humans.
Surprisingly, the Shilatifard Team could show that the catalytic activity of COMPASS is not necessary for viability of drosophila. Furthermore, they found that catalytic activity was not the decisive feature of the complex, but rather its role in the context of chromatin structure, in particular a protein domain that only spans 80 amino acids within the 4000 amino acid protein.
Effects of Non-Enzymatic Covalent Histone Modifications on Chromatin (Yael David)
In this episode of the Epigenetics Podcast, we caught up with Yael David from Memorial Sloan Kettering Cancer Center in New York to talk about her work on Effects of Non-Enzymatic Covalent Histone Modifications on Chromatin.
The David lab studies on non-enzymatic covalent modifications of Histones, including Histone glycation and citrullination. These modifications recognize metabolites that are produced in the cell and aid as a sensor for chromatin to quickly adapt to cellular changes. These unique modifications do not have a so-called erasing enzyme, which makes them terminal, rendering these sites inaccessible for further modifications such as methylation or acetylation.
A second area of research in the David lab is Histone H1. The lab has developed a new method to purify Histone H1, superior to the commonly used method of acid extraction which leads to degradation of Histone H1. This purification method enabled the lab to purify and characterize the functional properties of all Histone H1 variants.
ATAC-Seq, scATAC-Seq and Chromatin Dynamics in Single-Cells (Jason Buenrostro)
In this episode of the Epigenetics Podcast, we caught up with Jason Buenrostro from Harvard University to talk about his work on developing biological tools to measure chromatin dynamics in single-cells.
We hear the story of how in his early years in the lab, Jason took a risk and added an enzyme called Transposase to cells in culture. What he saw on an agarose gel astonished him. He was able to recreate a nucleosomal ladder similar to using MNase or DNase-Seq, without the tedious steps of optimization. In following years he optimized the method into what is known today as ATAC-Seq. In recent years he was also able to bring ATAC-Seq to the next level, developing single cell ATAC-Seq (scATAC-Seq), and combining it with RNA-Seq in a multi-omics approach.
In this Episode we discuss how Jason Buenrostro developed ATAC-Seq in William Greenleaf's lab, how a lack of equipment shaped the ATAC-Seq protocol, and how scATAC-Seq has enabled a whole different way of looking at biological samples.
Synthetic Chromatin Epigenetics (Karmella Haynes)
In this episode of the Epigenetics Podcast, we caught up with Dr. Karmella Haynes from Emory University to talk about her work on synthetic chromatin epigenetics, specifically on the design of synthetic chromatin sensor proteins. The first one of its kind, the Polycomb Transcription Factor (PcTF), senses H3K27me3 and recruits effector proteins to the sites of this modification. This sensor can be brought into cancer cells to activate hundreds of silenced genes. The lab hopes to characterize these effects genome wide and seeks to find a way to deliver those sensor into cancer cells, without affecting healthy cells.
In this Episode we discuss how Karmella Haynes got into the field of Epigenetics and the way she came to learn how important the right control experiments are. In the end we also discuss her activities to promote diversity and inclusion in science.

Identification of Functional Elements in the Genome (Bing Ren)
In this episode of the Epigenetics Podcast, we caught up with Bing Ren, Ph.D., from the University of California, San Diego and the Ludwig Institute for Cancer Research to talk about his work on identifying functional elements in the genome and higher order genome structure.
Dr. Ren’s lab invented an approach for finding cis-elements that involves the identification of transcription factor binding sites and chromatin modification status genome-wide using chromatin immunoprecipitation-based methods. His group demonstrated that this is an effective approach for genome-wide mapping of cis-elements, and their approach has now been widely adopted in the field. Among many other distinctions, Bing Ren's group was also a major contributor to the ENCODE Project.
In this interview, we discuss the path Bing Ren has taken so far on scientific career, his role in the ENCODE Project and Roadmap Epigenome Consortia, and the discovery of topologically associating domains (TADs).
Hi-C and Three-Dimensional Genome Sequencing (Erez Lieberman Aiden)
In this episode of the Epigenetics Podcast, we caught up with Erez Lieberman Aiden, Ph.D. from Baylor College of Medicine and Rice University in Houston to talk about his work on developing Hi-C and investigating the three-dimensional structure of the genome. He was the first author on a publication in the journal Science titled "Comprehensive Mapping of Long-Range Interactions Reveals Folding Principles of the Human Genome" which was the paper that first introduced the Hi-C method in 2009 and he has continued studying the structure of the chromosome ever since.
Erez Liebermann Aiden is currently an Assistant Professor in both the Department of Genetics at the Baylor College of Medicine, where he directs the newly-established Center for Genome Architecture, and in the Department of Computer Science and Computational and Applied Mathematics at Rice University across the street.

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.

Multiple Challenges in ChIP (Adam Blattler)
In this first episode of the Active Motif Epigenetics Podcast we chatted with Dr. Adam Blattler from the R&D team at Active Motif and discussed the multiple challenges of ChIP, the critical points of the ChIP protocol, as well as possible pitfalls.
Chromatin immunoprecipitation has become a very powerful method to study protein-DNA interactions, identify the binding profiles of DNA binding proteins, and determine whether specific proteins are associated with specific genomic regions. However, the workflow is complicated and involves many steps, so extensive experience and optimization are often required to achieve the best results.
