Dr Julia Horsfield

How signalling pathways interact with cohesin deficiency

Julia Horsfield graduated with a PhD in Biochemistry from the University of Otago in 1995, and did her postdoctoral research at the University of Adelaide 1996-1999. In a second postdoctoral stint as a Research Fellow at the University of Auckland, she was the first to discover a gene regulation role for cohesin in a vertebrate model – the zebrafish.

Since 2007, Julia has led the Chromosome Structure and Development Group at the University of Otago.  The overall goal of the group’s research is to understand chromatin mechanisms contributing to gene expression in development and cancer, using mammalian cancer cell lines, induced pluripotent stem cells, and of course, the zebrafish.

Seminar: How signalling pathways interact with cohesin deficiency

The cohesin complex plays key roles in the three-dimensional (3D) organisation of chromatin and is essential for cell division and gene expression.  Cohesin’s role in 3D genome organisation helps determine the accessibility of genes to transcriptional programmes downstream of signalling pathways. We and others have found that hundreds of genes are dysregulated upon cohesin deficiency, but it is not clear how this gene regulation could be ‘direct’. Our results show that minor gene expression changes in cohesin-deficient cells become dramatic in response to signalling pathways. Cohesin deficiency causes loss of constraints on 3D structure such that genes respond abnormally, transiently, when a signal is present, with dependence on enhancer function. Unconstrained 3D chromatin structure may not be the whole picture, because we recently found that the Wnt effector protein, beta-catenin, is stabilised in cohesin mutant cells. This raises the possibility that signalling pathways and cohesin mutation compound to abnormally regulate gene expression at multiple levels. Overall, these results have relevance to the interpretation of “cohesinopathy” human developmental syndromes, and a range of cancers, that are caused by mutations in the cohesin complex or its regulators.

1 – 2 pm (AEST)

Host: A/Prof Pilar Blancafort

Dr Lisa Marie Nicholas

Developmental programming of diabetes by maternal obesity – understanding the role of DNA methylation in pancreatic islets

Dr Lisa Marie Nicholas is an NHMRC C J Martin Fellow and leads the Epigenetics in Diabetes Research Group at the University of Adelaide. Lisa undertook her doctoral studies at the University of South Australia followed by post-doctoral training at Lund University Diabetes Centre where she investigated the role of mitochondria in maintaining pancreatic beta-cell function. Lisa then moved to the University of Cambridge where she defined early functional changes in the pancreatic islets of offspring exposed to maternal obesity leading to sex-specific differences in diabetes risk in later life.

Lisa continues to be fascinated by how a how a child’s metabolic destiny is determined even before birth by their mother’s metabolic health during pregnancy. Specifically, research in her group aims to discover the epigenetic networks in pancreatic beta-cells driving increased type 2 diabetes risk in offspring exposed to maternal obesity using mouse models and primary human islets.

Seminar: Developmental programming of diabetes by maternal obesity – understanding the role of DNA methylation in pancreatic islets

The rapid rise in diabetes incidence over the past decades has highlighted the role of epigenetics (in addition to genetics) in contributing to disease risk. This includes aberrant epigenetic changes resulting from in utero exposure to poor maternal nutritional states. Lisa will discuss whether DNA methylation has a role to play in mediating diabetes risk in offspring exposed to maternal obesity.

A/Prof Luke Selth

Flinders University, South Australia

Post-transcriptional regulation of prostate cancer cell plasticity

Associate Professor Luke Selth is head of the Prostate Cancer Research Group at Flinders University, South Australia, and a Beat Cancer Principal Research Fellow.

Research in the Selth Lab aims to elucidate how prostate tumours metastasise and become resistant to therapies, with a particular focus on non-genomic mechanisms. Luke and his group feed this newly gained knowledge into translational research projects aimed at developing new drugs and biomarkers to improve patient outcomes.

To achieve these research aims, the Selth lab exploits a unique assortment of model systems (including contemporary patient-derived models) and cutting-edge omic techniques.

The Selth lab is currently funded by Cancer Council SA, Movember, The Hospital Research Foundation, the Flinders Foundation and Cancer Australia.

Post-transcriptional regulation of prostate cancer cell plasticity

Targeted therapies in prostate cancer can cause epithelial tumours to switch to a neuroendocrine phenotype, a resistance mechanism that is mediated primarily by non-genomic alterations. In this presentation, Luke will describe recent work from his lab in which they have characterised novel post-transcriptional mechanisms underlying epithelial-neuroendocrine plasticity and therapy resistance.

A/Prof Ozren Bogdanovic

Laboratory Head Developmental Epigenomics Lab, Garvan Institute of Medical Research, NSW
Canonical and non-canonical DNA methylation remodelling during early embryogenesis

Associate Professor Ozren Bogdanovic completed his undergrad studies at the University of Zagreb (Croatia) and his PhD at the Radboud University Nijmegen (the Netherlands). Upon the completion of his postdoctoral studies at the Andalusian Centre for Developmental Biology (Spain) and UWA (Perth), he started the Developmental Epigenomics Lab at the Garvan Institute of Medical Research in Sydney in 2017.

Since 2019, Ozren has held a joint position between Garvan and UNSW (School of BABS). His lab investigates the contribution of epigenetic mechanisms to embryogenesis, germline formation, and disease. The Developmental Epigenomics Lab employs teleost systems, CRISPR/Cas9 genome editing and genomics to study the developmental dynamics of epigenetic marks such as DNA methylation and histone modifications.


Canonical and non-canonical DNA methylation remodelling during early embryogenesis.

Early development is characterised by extensive DNA methylome reprogramming events; however, their exact function, biochemical mechanisms and evolutionary conservation remain enigmatic. In this seminar, Ozren will discuss how canonical (CG) and non-canonical (non-CG) methylation are reprogrammed during the earliest stages of teleost development, and the implications these have for our understanding of comparable events in mammals.

Thurs 15 April 2021

4 – 5 pm (AEDT)

Host: Prof Jeff Craig

Prof Wendy Bickmore

MRC Institute of Genetics & Molecular Medicine,  The University of Edinburgh, UK

The role of spatial proximity in genome regulation

Professor Wendy Bickmore is Director of the MRC Human Genetics Unit, Institute of Genetics and Molecular Medicine at the University of Edinburgh, UK.

Wendy is fascinated by the structure and organization of chromatin in the nucleus. Her group showed that different human chromosomes have preferred positions in the nucleus, related to their gene content, and addressed how genes are organized and packaged in the nucleus and how they move in the cell cycle and during development. She demonstrated that the polycomb repressive complex functions by compacting higher-order chromatin at target loci.

Current research in Wendy Bickmore’s laboratory focuses on how the spatial organization of the nucleus influences genome function in development and disease, including how distant enhancers communicate with their target gene promoters.

Wendy is an EMBO member, a Fellow of the Royal Society and of the Academy of Medical Sciences. She is an editor on many journals including PLoS Genetics and Cell. She was the president of the Genetics Society of Great Britain from 2015 to 2018 and was awarded a CBE in the 2021 New Year Honours List for services to biomedical science and for women in Science.

Professor Peter Jones

Van Andel Institute, USA

The whys and hows of DNA methylation

Professor Peter Jones was born in Cape Town, raised and attended college in Rhodesia (now Zimbabwe), and received his Ph.D. from the University of London. He joined the University of Southern California in 1977 and served as Director of the USC Norris Comprehensive Cancer Center between 1993 and 2011. Peter became Chief Scientific Officer of Van Andel Institute (VAI) in Grand Rapids, Michigan in 2014.

Peter’s laboratory discovered the effects of 5‑azacytidine on cytosine methylation and first established the link between DNA methylation, gene expression and differentiation.

Peter has helped pioneer the field of epigenetics, particularly its role in cancer, and helped develop novel cancer therapies. He has published more than 300 scientific papers and received several honors, including an Outstanding Investigator Award. He and Stephen Baylin shared the Kirk Landon Award for Basic Cancer Research from the AACR in 2009 and the Medal of Honor from the American Cancer Society in 2011.

Peter is a past President of the AACR and was elected a Fellow of the American Association for the Advancement of Science in 2009 and a Fellow of the Academy of the AACR in 2013. He was elected a member of the National Academy of Sciences of the USA in 2016, the American Academy of Arts and Sciences in 2017 and received an honorary D.Sc. from Stellenbosch University in 2018.

The whys and hows of DNA methylation

The origins and functions of DNA cytosine methylation remain enigmatic even after more than 50 years of intensive research. I will re-examine Bestor’s hypothesis that the original appearance of DNA methylation is linked to its ability to silence intragenomic transposable elements (TEs). Because cytosine methylation is inherently mutagenic and leads to diagnostic C-T transitions at methylated CpG sites in the germline, CpG depletion can be used as a surrogate for ancient methylation. We examined the distribution of CpG sites in the published whole genome sequences of 53 organisms. We found a strong correlation between CpG depletion and genome size which in turn is largely dependent on the quantity of TEs it contains. This finding provides evidence for an unrecognized function of DNA methylation which is to enable genome expansion. Given the importance of CpG methylation in this process, as well as in gene control in health and disease, the mechanisms for de novo methylation need to be understood in more detail. While the chemical mechanisms by which methyl groups are applied to the 5 position of the cytosine ring are well understood, this process is much more complicated in the context of chromatin particularly because nucleosomal DNA cannot be methylated by prokaryotic or eukaryotic methylases. We used the power of Cryo-EM to solve the structure of a tetrameric complex of two molecules each of human DNMT3A2 and DNMT3B3 bound to a nucleosome core particle. Unexpectedly, the catalytically inactive DNMT3B3 acts as an accessory protein for the potentially active DNMT3A2. This binding occurs through the involvement of the acidic patch on the nucleosomal histones whereas the DNMT3A2 is positioned on the linker DNA. The structure predicts that the nucleosome must be moved or remodeled for de novo methylation to occur as is predicted in several publications. Understanding the whys and hows of DNA methylation will help in understanding its multiple roles in health and disease.

Novel epigenetic driven re-invigoration: progress from mechanism to therapeutics in immuno-oncology

Professor Sudha Rao has extensive experience in transcriptional biology and genomic technologies that spans both pharmaceutical and academic settings. The primary focus of Sudha’s research group is to unravel complex epigenetic-signatures in the immune system, as well as to understand the deregulatory mechanisms operating in cancer settings.

Sudha obtained her PhD from the University of London, Kings College in 2000. During this period, she joined a team of scientists at Rhone Poulenc/Sanofi Pharma, both in UK and France. During this time, she was part of one of the first groups world-wide to establish the clinical genomics platform for therapeutics in the UK.

Sudha has developed close partnerships with global technology companies and established novel liquid biopsy clinical platforms, first of its kind in Asia, for non-invasive tracking of blood samples from cancer patients. She has attracted highly competitive NHMRC, ARC and commercial funding to advance her cancer work. Sudha’s work has yielded national and international patents for both novel diagnostics and therapeutics in the emerging arena of immune-oncology and this work has great potential for cancer patients.

Professor Jus St. John

The University of Adelaide

Genomic balance

Professor Jus St. John is based in the Robinson Research Institute and The School of Medicine at The University of Adelaide. His research focuses on understanding how mitochondrial DNA is replicated and transmitted during development.

Jus uses a variety of assisted reproductive technologies and stem and tumour-initiating cell models to show how mitochondrial DNA replication is regulated in oocytes, embryos and undifferentiated and differentiating stem cells and why mtDNA replication is important to developmental outcome. His work indicates that the nuclear and mitochondrial genomes should be in synchrony for mitochondrial DNA replication and cellular differentiation to take place.

Jus has further shown that modulating the nuclear genome through, for example, DNA demethylation agents can impact on mitochondrial copy number. Likewise, modulating mitochondrial DNA copy number or haplotype can alter the global DNA methylation profiles of the nuclear genome. In cells that have established genomic balance, these actions can result in arrest whilst, in tumour-initiating cells, this can promote differentiation.

Dr Alyson Ashe

The University of Sydney

Insights into transgenerational epigenetic inheritance from C. elegans

Dr Alyson Ashe is an early career research fellow in the School of Life and Environmental Sciences at The University of Sydney. She is interested in all areas of epigenetics and small RNA molecules.

Alyson studies epigenetic regulation of gene expression: the interplay between the environment that an organism encounters during its lifetime, and the expression patterns of its genes. Importantly, these environmental signals can sometimes get passed between generations (Darwin was wrong!), and Alyson’s work is trying to understand how this occurs.

To do this Alyson mainly uses the model organism C. elegans, a small nematode worm, but is also branching out into other species such as the honey bee.
