Abstract
Aurora-A kinase is an important regulator of the cell cycle and many other processes beyond. It also plays an important role in cancer so that it has become an important drug target. However, the success of Aurora-A targeted drugs at present is rather mixed so that a better understanding of this complex enzyme is required. Aurora-A is an unusual kinase that lacks a canonical on-off switch and its activity can be regulated by a combination of interactions with a plethora of accessory proteins and phosphorylation on multiple sites. I will present how NMR spectroscopy has been used in my group over the past years to make important contributions to better understand this enigmatic protein and its partners. This will include the redefinition of the domain architecture of the XMAP215 family (1), structure determination of a novel cryptic TOG domain (1,2) and its partner 4/5 helix domain (1,4), studies of conformation and interactions of small fragments of TACC3 with Aurora-A kinase (3,5), early stages of the development of novel anti-cancer drugs and a first glimpse of the conformation of the overlooked N-terminus of Aurora-A kinase.
Biography
Mark Pfuhl was born in Berlin where he went to school and where he initially studied Chemistry at the Technische Universität before moving on to Biochemistry at the Freie Universität. After graduating there in 1991 he moved to EMBL Heidelberg where he did his PhD in the group of A Pastore using NMR to determine the first structures of domains of the giant muscle proteins Nebulin and Titin. He finished his PhD in 1995 and - after a brief stint at the Université de Haute Normandie with F Toma in early 1996 - he moved to London on an EMBO long term post doc fellowship to work with P Driscoll at UCL. In 1998 he obtained a Royal Society University Research Fellowship for independent research at UCL. In 2001 he moved to the University of Leicester where he held a Lectureship in addition to his fellowship. In 2010 he returned to London to hold a Readership in cardiovascular structural biology in the then Randall Division of molecular and cellular biophysics. His main scientific interests are the regulation of muscle and kinase function which he studies using mainly NMR spectroscopy supported by other biochemical and biophysical methods.

Back on Track
For a few months the Volta website has been silent as much of the communication between the College and its students took place by internal emails.
The Covid-19 pandemic affected our College as it affect other Colleges in Pavia and other Collegiate Universities. But two points clearly emerged from the crisis caused by the SARS Cov-2 virus:
(i) Many Volta students elected to stay in College throughout the lockdown months. Although the College does not have the full data from other Colleges in Pavia it is clear that the occupancy of Volta throughout lockdown has been one of the highest if not the highest across University. And fortunately no Volta student has been infected by the virus or at least not in a recognisable, symptomatic way.
(ii) Volta made the point that teaching ought to continue throughout lockdown and College is indebted and very grateful to the following students (listed alphabetically): A Barone, G Burini, M Freiherr von Wangenheim, V Mangiaterra, S Merlini. D Nodari, O Najlani, I Rosignoli and the following external students or post-doctoral fellows (in alphabetical order): S Burgess, S Fofou Fotchi, P Minerba (a Volta alumnus), M Musci, E Naldi and I Rossinelli.
Together these students and post docs delivered 168 hours of Course material and 264 of supervisions, the majority of which was offered online, often with the help of graphic tables and unquestionably the teaching that College carried out notwithstanding Covid-19 and the ensuing lockdown contributed in a major way to the strong academic results achieved by the members of Volta by the end of July deadline and to be presented at the General Assembly that will take place early in October.
Volta and its members sincerely hope that the worst of the SARS Cov-2 may now be over but the College will maintain the strictest vigilance and enforce tight discipline in order to try and keep the virus outside the College boundaries and enable our students to have a safe and productive 2020/21 academic year at Volta.

Abstract
Blood cells sustain life through oxygen supply and resistance to infection. The hematopoietic system is a source of limitless production of blood cells. Genetic and environmental defects in this system causes hematologic cancers, anemias, and bone marrow failure syndromes. The ultimate goal of our study is to produce blood cells on petri dish so that can be transfused to patients [1]. To do so, understanding how blood cells develop in our body is essential. Blood cell development depends on network of cells. I propose the organ-on-a-chip platform to study network of cells in blood development [2]. This study will ultimately provide a fundamental molecular mechanism of human blood cell development.
Biography
My academic background comprises ten years of professional research experience as a stem cell biologist. I studied the role of microenvironmental signals in the maintenance of hematopoietic stem cells [3,4] and identified gene regulatory networks able to induce the formation of hematopoietic stem cells from human pluripotent stem cells [1]. At iPS Cell Research and Application (CiRA) based at Kyoto University, my research program focuses on understanding molecular mechanisms of human developmental hematopoiesis. My career goal is to contribute to regenerative medicine by bridging expertise in human developmental hematopoiesis and pluripotent stem cells.

Abstract
Despite rapid technological progress, the discovery of novel antibiotics has been stalled for the past 50 years. To combat the growing burden of antibiotic resistance, innovative drug discovery paradigms are required to improve and expedite the antibiotic discovery process. A crucial bottleneck in drug discovery is the identification of compounds’ Mode of Action (MoA). To address this problem we developed a rapid and systematic metabolome profiling strategy to classify the MoA of bioactive compounds. In contrast to existing methods based on phenotypic drug profiling, mostly on the basis of growth assays, we exploit here the intracellular response of about 1000 metabolites as a truly multiparametric readout of the cellular response. The specific advance over existing metabolic platforms is a faster throughput of 1-2 orders of magnitude, allowing our combined MS-based metabolomics and computational workflow to scale with the size of typical compound libraries. I will illustrate how this technology enables monitoring the metabolic response of Escherichia coli to 1279 human targeted drugs and revealed an unexpectedly large spectrum of metabolic effects in E. coli. Combining metabolic profiling with chemogenomic data, we predicted drug MoAs and epistatic drug interactions. Our approach opens new opportunity in systems pharmacology and reveals new ways to expand the search for new antimicrobial treatments to compounds with no growth-inhibitory activity (keywords: Metabolomics, Antibiotics, Drug Mode of Action).

Multiplexed genome engineering by Cas12a and CRISPR arrays encoded on single transcripts
On the 14th of November 2019 Carlo Cosimo Campa, ETH Zurich, will give a seminar entitled Multiplexed genome engineering by Cas12a and CRISPR arrays encoded on single transcripts at 5.00 pm in the College lecture theatre (Collegio a Volta).

Abstract
The ability to modify multiple genetic elements simultaneously would help to elucidate and control the gene interactions and networks underlying complex cellular functions. However, current genome engineering technologies are limited in both the number and the type of perturbations that can be performed simultaneously. Here, we demonstrate that both Cas12a and a clustered regularly interspaced short palindromic repeat (CRISPR) array can be encoded in a single transcript by adding a stabilizer tertiary RNA structure. By leveraging this system, we illustrate constitutive, conditional, inducible, orthogonal and multiplexed genome engineering of endogenous targets using up to 25 individual CRISPR RNAs delivered on a single plasmid. Our method provides a powerful platform to investigate and orchestrate the sophisticated genetic programs underlying complex cell behaviours.

Biography
Carlo Campa has a background in industrial biotechnology (B.Sc. and M.Sc. – University of Turin). He started his PhD studies at the PI3Ks Signalling Laboratory of University of Turin (Prof. Emilio Hirsch). For his postdoc, he moved to ETH Zurich at the Laboratory of Biological Engineering (Prof. Randall J. Platt – ETH Zurich) where his research activities are focused on the development of novel genome engineering tools. He has provided seminal contributions in the characterization of membrane dynamics and lipid signalling in embryogenesis and immunity (Developmental Cell 2014, Science Signalling, 2016, J. Immunol. 2013). Together with Kither Biotech s.r.l. he developed and exploited inhibition of lipid signalling to treat chronical airway diseases (Nature Communication 2018). He demonstrated the role of endosomes as a signalling platform in embryo development, and insulin resistance (Developmental Cell 2014, Nature Communication 2015). He defined that temporal control of signalling events provides a strategy to govern stochastic egression of neutrophils from the bone marrow (Science Signalling, 2016). He realized the first class of biosensors able to detect signalling events on endosome membrane microdomains and he provided the evidence that activation of endosomal signalling enables receptors exit from endosomes (Nature Chem. Biol 2018). Recently, he assessed the scaffold function of a lipid kinase in cancer resistance (Cancer Cell 2017) and I generated new genome editing tools for fast rewiring of complex pathways in cells (Nature Methods, 2019). By conducting investigations at the interface between biology, mathematics and engineering, he has aimed at defining both the design principles and the molecular mechanisms by which cells make decisions.

Dissecting cytosine modifications
31st October 2019.
Francesco Spallotta, Institute for Cancer Research, Candiolo
On the 31st of October 2019 Francesco Spallotta of the Institute for Cancer Research in Candiolo will give a seminar entitled Vaccines: Dissecting cytosine modifications at 2.00 pm in the College Lecture Theatre. In his talk F Spallotta will discuss recent advances in the understanding how chemical modifications of cytosine, one of the four bases found in DNA, can affect gene expression not only during embryogenesis and in normal tissues but also in major diseases such as diabetes and cancer. The poster of the seminar can be downloaded here. All College students are warmly invited to participate.
Abstract
Cytosine methylation harnesses chromatin plasticity and gene transcription affecting cell functions and fate. Recently an active biological role has been assigned to different stable cytosine iterative modifications enriched during DNA demethylation cycle including 5-hydroxy- and 5-formyl-cytosine. Metabolite availability directly regulates DNA (de)methylation enzymatic machinery, as the involved enzymes, DNA methyltransferases, Tet methylcytosine dioxygenases (TETs) and Thymine DNA Glycosylase (TDG), exploit S-Adenosyl methionine and α-ketoglutarate (αKG) to exert their activity. Consequently, metabolite availability can ultimately influence the levels of different cytosine modifications. In this light, in the tumor microenvironment, the balance between αKG and oncometabolites, including 2-hydroxyglutarate (2HG), succinate and fumarate, plays a crucial role in the regulation of DNA demethylation. In first part of my talk, I will show how chronic metabolic derangement associated to type 2 diabetes and cancer affects intracellular balance between αKG and 2HG, thus altering DNA (de)methylation cycle. Specifically, we recently published that cardiac mesenchymal cells isolated from diabetic donors show reduced levels of αKG in comparison to the ones isolated from normoglycemic donors. The decreased availability of αKG associates to an altered cytosine methylation pattern consequence of a compromised TET/TDG association and function with TET1 relocation out of the nucleus. In the second part of the talk, I will show preliminary data about the effect of chronic dysmetabolism, achieved by high-fat diet, on a genetically engineered mouse model of pancreatic ductal adenocarcinoma (PDAC). Specifically, I will show the impact of dysmetabolism on the αKG/oncometabolite balance and the cytosine modification levels. Moreover, the effect of oncometabolite enrichment on pancreatic stellate cells and cancer associated fibroblasts isolated from pancreas of PDAC patients will be discussed. Lastly, the efficacy of epi-metabolic compounds, aimed at restoring the epi-metabolic control of DNA methylation cycle, will be showed in rescuing type 2 diabetes-dependent cardiac features and in preventing breast cancer associated lung metastasis. Specifically, the novel compound (S)-2-[(2,6-dichlorobenzoyl)amino]succinic acid (AA6), identified as an inhibitor of αKG dehydrogenase, increased the αKG level in diabetic cardiac mesenchymal cells and in the heart of hyperglycemic mouse models eliciting DNA demethylation, glucose uptake, and insulin response. The same compound was tested in an orthotopic mouse model of breast cancer. Also in this context, AA6 altered Krebs cycle causing intracellular αKG accumulation and, consequently, the activity of TETs was restored. In mice, AA6 injection reduced metastasis formation and increased 5hmC levels in primary tumours. This epigenetically remodelled metabolic environment efficiently counteracted the initiating steps of tumour invasion inhibiting the epithelial-to-mesenchymal transition (EMT).

Biography
F. Spallotta is a senior research fellow at Department of Oncology, Turin University (Turin-Italy) located at Candiolo Cancer Institute FPO-IRCCS. From 2005 to 2010 he was Master of Science student and PhD student at the Vascular Pathology Laboratory of the "Istituto Dermopatico dell'Immacolata-IRCCS" (Rome-Italy). From 2010 to 2012 he accomplished his PhD in Experimental Medicine and started his postdoctoral training at the Vascular Biology and Regenerative Medicine Laboratory of the “Centro Cardiologico Monzino-IRCCS” (Milan-Italy). From 2012 to 2018 he was one of the former postdoctoral fellow at the Division of Cardiovascular Epigenetics at Goethe University (Frankfurt am Main-Germany). Moving from one lab to another was extremely stimulating and enriched his background, giving him the opportunity to contribute to several research projects. F Spallotta has a strong expertise in cellular and molecular biology and he is extremely proficient with many cellular and in vivo models suitable to study different physio-pathological context. Since 2005, he worked in the field of epigenetics pointing out novel molecular mechanisms underpinning onset and progression of different human diseases. Since 2014, he started to explore the link between epigenetics and metabolism, especially in response to dysmetabolic contexts associated with diabetes, aging and cancer and established following specific dietary regimens, including high fat diet, fast mimicking diet and ketogenic diet. Recently he elucidated an altered DNA methylation pattern associated with reduced level of α-ketoglutarate in mesenchymal cardiac cells isolated from type-2 diabetic patients pointing out a mechanism at the molecular base of the so called “hyperglycemic memory” responsible for cardiovascular complications in diabetes. Moreover, he characterized the contribution of the same metabolite, α-ketoglutarate, during breast cancer-associated lung metastasis. At present he is investigating the link between colorectal cancer and pancreatic ductal adenocarcinoma with diabetes and obesity. In all his studies he applied integrative OMICS analysis by performing DNA methylome sequencing, ChIP-sequencing, RNA-sequencing and metabolome analysis.

Epigenetics and Disease
F Spallotta, a scientist at the Institute for Cancer Research in Candiolo (Italy) will give a seminar tomorrow Thursday the 31st of October at 2.00 pm in the College lecture theatre on the role of epigenetic processes in diseases such as diabetes and cancer. Epigenetic changes are subtle but stable chemical modifications of the genetic material (DNA) that influence in a fundamental way gene activity during development as well as in disease. The speaker will also address the prospect that new drugs interfering with the biochemical pathways responsible for epigenetic changes may find important applications in diabetes and cancer.
All College students are invited to participate, notably natural science and medical students. The poster of the seminar can be downloaded here. Further information about the seminar and speaker can be found at this page.
