SLC25A51 regulates the transport of the coenzyme NAD into the mitochondria
For their growth, cells need various nutrients and vitamins. So-called solute carriers (SLC), proteins that can transport such substances across the boundaries of cellular membranes, play a central role in metabolism. Scientists in Giulio Superti-Furga’s research group at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences have now discovered that the previously uncharacterized protein SLC25A51 acts as a transporter into the mitochondria for the coenzyme NAD. This molecule has already been associated with numerous physiological and pathological processes such as ageing, neurological diseases and the metabolism of cancer cells. Therefore, the results of this study not only open up new possibilities to study the biological role of NAD but also potentially provide the basis for new therapeutic approaches. The work has now been published in the journal Nature Communications.
Solute carriers (SLC) are proteins that act as transporters and enable the entry and exit of nutrients and waste products into and from the cell and its organelles. Many of these transporter proteins are still relatively poorly studied and the question of how some nutrients enter and leave cells often remains unanswered. So far, it has not yet been clarified how mitochondria gain access to an important cofactor of our metabolism, the so-called NAD (nicotinamide adenine dinucleotide). In scientific literature, there were only references to mitochondrial NAD transporters in plants and yeast. Lead author Enrico Girardi and the research group of CeMM Scientific Director Giulio Superti-Furga, in cooperation with scientists from the University of Bari (Italy), have now identified the protein responsible for the important transport of NAD into mitochondria: SLC25A51.
The study "Epistasis-driven identification of SLC25A51 as a regulator of human mitochondrial NAD import" was published in Nature Communications on 1 December 2020. DOI: 10.1038/s41467-020-19871-x

TASL is the SLC15A4-associated adaptor for IRF5 activation by TLR7–9
How cells recognize pathogens and alert the immune system is a fundamental process of high importance for the survival of any species, including humans. A key role is ascribed to so-called adapters, that equal little molecular platforms inside cells where signals from pathogen detectors are integrated for safety and accuracy and conveyed to lasting signals leading to the activation of the major “red alarm” genes, like interferons. Researchers from the lab of Giulio Superti-Furga in collaboration with Boehringer Ingelheim in Ridgefield (US) have identified a new key element of the multi-component machinery that is responsible for sorting out the nature and severity of the pathogen challenge. The new protein, named TASL, is indispensable for the signaling of so-called Toll-like receptors (TLR) in the endosomes leading to activation of the gene-activator IRF5 in certain immune cells. Sensitive “tuning” of the machinery is highly important as too much output causes inflammation also in the absence of the pathogen, as in auto-immune diseases. This particular version of the machinery seems particularly associated with disorders such as systemic lupus erythematosus (SLE). This discovery highlights a potential new target for the development of drugs to treat certain autoimmune diseases and possibly also overreaction to viral and other infections and has been published in the renowned scientific journal Nature.
Previous studies revealed that SLC15A4, a member of the body’s biggest family of transporter proteins, was known as an essential component required for the correct function of these TLRs. Based on their strong research interests in pathogen-sensing by the innate immune system and the characterization of solute carriers, researchers in the group of Giulio Superti-Furga set out to investigate how SLC15A4 influences the ability of TLRs to sense pathogens, and, consequently, gain a better understanding on its implication in autoimmune conditions, and in particular SLE.
In their study, first author Leonhard Heinz and the team, including Boehringer Ingelheim researchers, undertook a precise investigative work, not taking for granted previous findings on SLC15A4 and the connection to this group of specially located TLRs. They painstakingly determined by biochemistry and mass spectrometry the molecular interactions that involved SLC15A4. This led to the identification of an uncharacterized protein CXorf21, belonging to the functionally orphan genes that are merely numbered and assigned to the chromosome of origin. The gene, like SLC15A4, had been previously loosely associated with SLE.
The team demonstrated that the interaction between TASL and SLC15A4 was crucial for the localization and function of the TASL protein and could pinpoint the precise involved portions of both proteins. A eureka moment for the understanding of the protein came with the observation that TASL harbors a specific motif essential for the recruitment and activation of IRF5. “After STING, MAVS and TRIF, the new protein TASL is the fourth key innate immunity adaptor functioning as a platform for the encounter of a kinase and a gene activator of the IRF family”, says Manuele Rebsamen, CeMM senior postdoctoral fellow and project leader of the study.
This study is the result of a collaboration between CeMM and the Drug Concept Discovery Group led by Charles Whitehurst and JangEun Lee in the Immunology and Respiratory Diseases Department at Boehringer Ingelheim (Ridgefield, CT, USA). Researchers also benefited from the support of the Proteomics and Metabolomics (Pro-Met-) facility and the Biomedical Sequencing Facility (BSF) at CeMM.

A widespread role for SLC transmembrane transporters in resistance to cytotoxic drugs
Researchers around first author Enrico Girardi of the Giulio Superti-Furga lab at CeMM have studied how Solute Carriers (SLCs), a large family of membrane transport proteins, influence the activity and potency of cytotoxic drugs. The results show that many cytotoxic compounds need at least one functioning solute carrier transporter to unfold their activity. "The use of a custom-made, SLC-focused library was instrumental in allowing us to screen a large number of compounds, revealing hundreds of SLC-drug associations and providing many novel insights into SLC biology and drug mechanisms", says Enrico Girardi, CeMM senior postdoctoral fellow and first author of the study. Giulio Superti-Furga, CeMM Scientific Director and last author of the study adds: "This study raises strong doubts that the generally accepted idea that most drugs can enter cells by simply diffusing through its membrane is correct and highlights the increasingly appreciated need to systematically studying the biological roles of solute carriers". The present study is the result of a cross-disciplinary collaboration with researchers from the University of Vienna Pharmacoinformatics Research Group of Gerhard Ecker as well as the group of Stefan Kubicek at CeMM.

New mechanism controlling the master cancer regulator uncovered
Who regulates the key regulator? The Superti-Furga laboratory at CeMM reports online in the journal Science about a newly discovered mechanism by which RAS proteins, central to cancer signaling, are regulated in their activity and localization.
Of the more than 23,000 genes in the human genome, only a handful assume a very central role in signal transduction and growth regulation. Of these, the three genes encoding RAS proteins are particularly important, as they are found mutated in over 25% of human cancers. The processes around the RAS gene products are also involved in a variety of rare human developmental disorders called the RASopathies. RAS proteins are absolutely central regulators of growth and oncogenesis and, in turn, every regulator of RAS is poised to be fundamentally important for cancer and a broad variety of human diseases.
Driven by the interest in identifying underlying genetic determinants of drug response in a specific type of cancer of the hematopoietic system, CeMM now reports on the mechanistic link between the LZTR1 gene, previously associated with a variety of rare disorders and rare cancers, and RAS. These findings provide a new key regulator of a pathway that is one of the best studied signaling pathways in biology. As such, it represents a major advancement. The study not only sheds new light and details on the regulation of a central growth-promoting protein, but also offers a molecular explanation for an unusually large number of pathological conditions, ranging from different types of brain and pediatric cancers to developmental pathologies like Noonan syndrome.
The research team found that the protein called LZTR1, in concert with its copartner cullin 3, regulates RAS by attaching to it a small molecular tag, called ubiquitin. The modified RAS proteins demonstrate altered localization within the cell and reduced abundance. Mutational defects or inactivation of LZTR1 lead to an increase of RAS dependent pathways causing dysregulation of growth and differentiation. LZTR1 can therefore be considered a breaker of RAS action.

How immune cells kill bacteria with acid
The first line of immune defense against invading pathogens like bacteria are macrophages, immune cells that engulf every foreign object that crosses their way and kill it with acid, in a process called phagocytosis. In their quest to systematically study proteins that transport chemicals across cellular membranes, researchers at CeMM characterized the critical role for transporter SLC4A7 in this process, providing valuable new insights for many pathologic conditions from inflammation to cancer. Their results were published in Cell Host & Microbe.
Among the many different kinds of immune cells that patrol the body, macrophages are the first when it comes to fight against a foreign threat. With their flexible and versatile surface, they engulf every microorganism or particle that could be harmful for the health of the organism, and enclose it in an intracellular membrane vesicle called phagosome. To eliminate the threat and break it down to its constituents, the interior of the phagosome needs to be effectively and progressively acidified. For this crucial part of phagocytosis, the macrophages must undergo multiple metabolic changes, which are not yet entirely understood.
The team of Giulio Superti-Furga, Scientific Director of CeMM, in collaboration with the laboratory of Nicolas Demaurex of the University of Geneva, discovered in their latest study that a membrane protein belonging to the family of “solute carriers” (SLCs) plays an essential role in phagocytosis and phagosome acidification. Their work was published in the journal Cell Host & Microbe (DOI 10.1016/j.chom.2018.04.013).
The researchers developed an essay with special cells in which they impaired the 391 human SLC genes individually using CRISPR/Cas9 gene editing technology. Strikingly, among all SLCs, SLC4A7, a sodium bicarbonate transporter, was the only one who turned out to be essential for macrophages to undergo phagocytosis and acidification. Cells with impaired SLC4A7 were unable to acidify their phagosomes and by consequence decreased their capacity to kill bacteria.
The results of this study do not only provide new fundamental insights into the molecular functioning of one of the most important cells of the immune system. As phagocytosis plays a significant role in various pathologic conditions from inflammation to cancer, these new insights are likely of relevance beyond the context of infectious diseases. The effort to understand the role of the different cellular transporters, supported by a grant of the European Research Council (ERC), has added a small new piece to the large and fascinating puzzle coupling trafficking of chemical matter to metabolism and cellular function.

A New Achilles’ Heel of Blood Cancer
Acute Myeloid Leukemia (AML) is an aggressive form of blood cancer that frequently develops in children. The diseased cells often carry mutated forms of a specific gene, which is known to function within large protein networks. Researchers at CeMM and LBI-CR identified a protein of this network crucial for the survival of the cancer cells – a novel potential approach for targeted therapies. The study was published in Nature Communications.
AML is not a single disease. It is a group of leukemias that develop in the bone marrow from progenitors of specialized blood cells, the so-called myeloid cells. Rapidly growing and dividing, these aberrant cells crowd the bone marrow and bloodstream, which can be fatal within weeks or months if the disease is left untreated. Myeloid cells of various types and stages can become cancerous and cause AML, which makes the condition very heterogeneous and difficult to treat. Thus, finding drug targets that affect as many forms of AML as possible is a prime goal for researchers.
The research groups of Florian Grebien from the Ludwig Boltzmann Institute for Cancer Research, Giulio Superti-Furga, Scientific Director of the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences, and Johannes Zuber, from the Institute of Molecular Pathology, tackled that question in their latest study. They were able to identify common, conserved molecular mechanisms that drive oncogenesis in the context of the large number of different MLL-fusion proteins by characterizing the protein-protein interaction networks of distantly related MLL fusion proteins. Their results were now published in Nature Communications (DOI:10.1038/s41467-018-04329-y)
The scientists identified the methyltransferase SETD2 as a critical effector of MLL-fusion proteins. Using genomic techniques including CRISPR/Cas9 genome editing, the researchers found that SETD2 loss caused induction of DNA-damage and ultimately cell death in the cancer cells. Moreover, SETD2 loss increased the lethal effect of Pinometostat, a drug that is currently in clinical development for treatment of leukemia patients with MLL fusions. These experiments might pave the way for a more effective therapy in the future using a combination of compounds.

Next-Generation Microscopy with Pharmacoscopy
A novel microscopy method, developed and patented by scientists from CeMM, allows unprecedented insights into the spatial organization and direct interactions of immune cells within blood and other liquid multi-lineage tissues. The assay, called Pharmacoscopy and published in Nature Chemical Biology, is able to determine the immunomodulatory properties of drugs within large libraries on immune cells in high resolution and high throughput.
The search for new drugs, small molecule or biologicals, that influence the immune system in a desired manner is challenging: immune signaling, often a combination of communication via soluble proteins and direct interaction by cell-cell contacts, is subtle and hard to track in all its nuances. So far, there has been a lack of fast and robust technology to measure the effect of a potential immunomodulatory drug in particular in a cell-cell contact dimension.
By combining state-of-the-art high-throughput fluorescent microscopy with single cell image analysis and novel analysis algorithms, Pharmacoscopy provides a powerful solution. Developed by a group of scientists at CeMM led by Director Giulio Superti-Furga and tested in collaboration with the Medical University of Vienna, Pharmacoscopy can quantify the overall spatial patterning and direct interactions of immune cells within blood with unprecedented speed and accuracy. The method was introduced in Nature Chemical Biology (DOI:10.1038/nchembio.2360).
Combined single cell resolution and fully automated platform control, Pharmacoscopy can test large drug libraries, as available in Stefan Kubicek’s PLACEBO (Platform Austria for Chemical Biology) laboratory, for compounds with immunomodulatory potential. With this method, the scientists identified Crizotinib, an FDA approved drug for non-small cell lung cancer, to have a previously unknown immunomodulatory potential.

Kickoff for Pharmacoscopy – a novel tool for precision medicine
In light of the importance of research on precision, molecular, and personalized medicine, CeMM and the Medical University of Vienna hosted on March 6, 2017 a kick off meeting to celebrate the start of Pharmacoscopy, a novel high-content screening and imaging platform to break resistance of relapsed and refractory hematological malignancies - a true bench-to-bedside circle.
This meeting presented and celebrated the collaborative project between the Superti-Furga and Kubicek laboratories at CeMM and the Division of Hematology and Hemostaseology, Department of Internal Medicine I of the medical University of Vienna. The Pharmacoscopy platform is funded with the precision medicine grant from the WWTF (Wiener Wissenschafts-, Forschungs- und Technologiefonds / Vienna Science and Technology Fund) awarded to Giulio Superti-Furga and Ulrich Jäger.
The meeting began by reviewing the importance of the strong CeMM and MedUni Wien collaborative atmosphere that has propelled basic and translational science, as reiterated by the Vice Rector for Research and Innovation Michaela Fritz. Christoph Zelinski, Director of the Department of Internal Medicine I, touched upon ongoing precision medicine programs in the MedUni Wien such as the EXACT trial. Ulrich Jäger, Head of the Division of Hematology and Hemostaseology, further spoke about the need for personalized and precision medicine in the hematological space, where functional testing that will be used to meet the aims of the WWTF grant can synergize with genetic testing that is clinically routine.
CeMM scientific Director Giulio Superti-Furga and his Senior Postdoctoral Fellow Gregory Vladimer outlined the image-based screening platform that is the backbone of this program, and how the technology is currently being used for clinical utility. The meeting was finished by Ulrich Jäger presenting interim results of an ongoing clinical study aimed at describing the benefits of data generated through this collaboration for the treatment of patients.
The Pharmacoscopy project aims to break resistance of refractory blood cancers through ex vivo automated image-based analysis of drug action, and potentially drive clinical trials of already approved drugs in off-indication blood cancers. The approach provides a very concrete and actionable platform for precision medicine and the use of off-indication approved drugs for late stage hematological malignancies. The collaboration is tuned directly to unmet clinical needs of resistant blood cancer patients.

Giulio Superti-Furga new Member of Scientific Council of the European Research Council (ERC)
Giulio Superti-Furga, Scientific Director of CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and Professor for Medical Systems Biology of the Medical University of Vienna has been appointed Member of the Scientific Council of the ERC, on the 10th anniversary of its existence, for a function period of 4 years.
The European Research Council is the most important and prestigious funding institution for basic research in any field conducted within the European Union. Excellence is the sole criterion for selection; there are neither thematic priorities, nor geographical or other quotas for funding. Perhaps the most important funding programme of the ERC is the ERC Starting Independent Research Grant, promoting early scientific independence of promising talents with 2 million Euros over a period of 5 years. It has created a very positive impact on the attractiveness of Europe as research area. But the ERC has also other programmes, such as the ERC Advanced Investigator Grant, which fosters innovation carried out by established scientists with a proven scientific track record of excellence. Having been awarded two ERC Advanced Investigator Grants over the years and two ERC Proof-of-Concept Grants, to explore the application potential of research ideas, Giulio Superti-Furga, who also acted as ERC panel member in the past, knows the ERC well and is well suited to offer his experience to the organization that this year celebrates its 10th anniversary.
The ERC is governed by the Scientific Council, consisting of eminent European scientists and scholars including Nobel Prize laureates. Members are nominated by an independent search committee and appointed by the European Commission. Since 2014 Professor Jean-Pierre Bourguignon, a renowned French mathematician, is President of the European Research Council. From 2010 to 2013 Professor Helga Nowotny, a Viennese Professor of Social Studies of Science held this prestigious position. She was also a founding member of the ERC in 2007. In 2017 the European Research Council is celebrating its 10th anniversary.
The ERC Scientific Council acts on behalf of the scientific community in Europe to promote creativity and innovative research. Giulio Superti-Furga: “It is a great honor to accept this important responsibility, which has had a tremendously positive impact on basic research in Europe. My aspiration is to contribute to a more science and innovation-friendly climate in Europe by promoting excellence in research and ensuring that politicians protect and promote the ERC as the most successful research funding scheme of the EU. Results from basic research accompany us at every step and should therefore become a core theme in everyday life - in education, in the media and in public discussions. Society and politics must have the courage to invest in new projects, to keep pace with scientific developments and associated implications. It is important to understand science as a fundamental component of our culture and of our future and a motor for innovation and competiveness also for the European industry."

2nd ERC Advanced Investigator Grant
Giulio Superti-Furga, scientific director at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and Professor of Medical Systems Biology at the Medical University of Vienna is to receive the Advanced Investigator Grant of the European Research Council ERC in the amount of approximately 2.5 million euro. The term for the prestigious grant is 5 years.
"ERC Grants are the most important promotions for life sciences in Europe. Unfortunately, the situation is becoming increasingly competitive due to budget cuts," says Giulio Superti-Furga who has built up and is leading CeMM at the campus of the Medical University of Vienna and the Vienna General Hospital: "I am all the more delighted to receive this extraordinary distinction as it also confirms the relevance and quality of CeMM research." The goal of CeMM is to prepare the precise medicine of the future by decoding molecular causes for important diseases such as cancer, inflammation and immune disorders. Giulio Superti-Furga already received an ERC Advanced Grant in 2009 for the exploration of basic immune system mechanisms. In 2011, he also received the first ERC Proof of Concept Grant in Austria.
The molecular system biologist has been granted the present ERC funding for research into existing components in cell membranes that transport dissolved substances into cells. Previous studies have shown that these "cell gates", so-called SoLute Carrier Proteins (SLCs) perform an important task in regulating the cellular metabolism and are responsible for accepting medications. The goal of the research project with the title "Game of Gates" is to decode the previously unknown rules according to which cells open or close their gates, either permitting or preventing the entry of substances. Giulio Superti-Furga: "Thus far, SLCs were treated more or less as second-rate by the scientific community. However, we expect that insights from our study will significantly contribute to a new, fundamental understanding of cellular physiology and thus prepare the way for the development of new, targeted therapies for various illnesses."
The ERC Advanced Investigator Grant is being awarded to Giulio Superti-Furga after two ERC Starting Grants had been given to Andreas Bergthaler and Christoph Bock in the autumn of 2015. Moreover, CeMM Principal Investigator Kaan Boztug won the bid – also in the autumn of 2015 – for founding the Ludwig Boltzmann Institute for Rare and Undiagnosed Diseases. The "Vienna Research Groups for Young Investigators" grant of the Vienna Science and Technology Fund WWTF had also been awarded to the CeMM PI Jörg Menche. All of these promotions once again emphasize the excellent work being performed at the CeMM.

A “hot” approach for understanding drug action and identifying new drug targets
How do successful drugs actually work? And how can we identify new targets for drug discovery to enable the development of novel potential therapeutics? A key challenge for scientists in academia and the pharmaceutical industry is to find out how small molecules such as drugs or cellular metabolites act within a cell – who are the mediators and effectors required for a drug or metabolite to exert their effect e.g. on cell proliferation, shape etc.? Based on the simple fact that interaction between a small molecule - such as a drug - and a given target protein increases the thermal stability of that protein, scientists at CeMM have developed a new state-of-art approach to reveal the cellular proteins that are engaged by small molecules and metabolites. By refining the established cellular thermal shift assay (CETSA) approach in which cells are treated with a small molecule and then heated to measure the differential protein stability upon target engagement and combining it with modern protein mass spectrometry a broad view of small molecule-protein interactions is provided. A particular advantage of the new methodology is the fact that the assay works with intact living cells and thus reflects a more natural (“physiological”) context in which the small molecule and its target proteins interact without any interference considering compound uptake, efflux, metabolism as well as cellular compartments. A potential future application includes the use of patient material to identify patient specific bio markers to enable personalized medicine.
