Ignaz L. Lieben Award for CeMM Adjunct PI Nuno Maulide

Congratulations to Nuno Maulide, Professor for Organic Synthesis at the University of Vienna, Corresponding Member of the Austrian Academy of Sciences, and CeMM Adjunct Principal Investigator, for receiving the Ignaz L. Lieben Award of the Austrian Academy of Sciences! As a scientist with a broadly documented expertise in state-of-the-art innovations in organic synthesis, and a great talent and dedication for science communication and teaching, Nuno Maulide highly deserves this prestigious award and recognition.

Nuno Maulide’s research mostly focused on unusual or "unconventional" reactivity profiles of organic compounds with a particular interest in high-energy reactive intermediates that can be generated under mild conditions and subsequently lead to rearrangements, domino reaction sequences or catalytic asymmetric transformations. One of his research goals at CeMM is translating the “precision design” that is enabled by synthesis, whereby modification and tailoring of organic molecules can be done with atomic precision, to the realm of biomedical research with an impact on medical practice.

Nuno Maulide is a trained chemist. He underwent doctoral studies in the Université catholique de Louvain and, in 2007, obtained his PhD working on the application of functionalized orthoesters in organic synthesis. He then moved to Stanford University for a post-doctoral stay. Nuno started his independent career in 2009, when he was appointed group leader at the Max-Plank-Institut für Kohlenforschung in Mülheim an der Ruhr. In 2013 he moved to the University of Vienna, taking up his current position as Full Professor of Organic Synthesis. Nuno is a holder of several ERC Grants, leads a Christian Doppler Laboratory and joined CeMM as Adjunct PI in November 2018. At the beginning of 2019 Nuno Maulide was elected Scientist of the Year by the Austrian Club of Education and Science Journalists.

The Ignaz L. Lieben Award founded in 1863 and named after the banking house Lieben is given to scientists for outstanding achievements in the fields of molecular biology, chemistry or physics. Since 2004 Isabel and Alfred Bader are generously sponsoring the prize. Renowned researchers such as the physicist Lise Meitner or the two Nobel Prize laureates Viktor Hess and Ott Loewi were awarded the Ignaz L. Lieben Prize in the past. In 2010, CeMM Principal Investigator Robert Kralovics received the prize for achievements in uncovering the genetic basis of myeloproliferative disorders.

Targeted drugs are a cornerstone of personalized medicine, yet come with important drawbacks. They restrain disease progression – but rarely eradicate the cancer. Patients therefore need to take the drugs essentially forever, exposing them to severe side effects and incurring high costs for the healthcare system. Combination therapies could potentially overcome these limitations. A study by scientists from CeMM, the Research Center for Molecular Medicine of the Austrian Academy of Sciences in collaboration with the Medical University of Vienna shows how epigenetic analysis and automated microscopy help prioritize new drug combinations for leukemia therapy. The results were published in Nature Chemical Biology(DOI: 10.1038/s41589-018-0205-2) on 28 January 2019.

A catalog of the human kinome in response to genotoxic stress, induced by chemotherapeutic agents

Graphical Abstract: Owusu et al., 2019, Cell Reports 26, 555–563, January 15, 2019. https://doi.org/10.1016/j.celrep.2018.12.087

An important group of genes that is frequently mutated in cancer consists of kinases, which mediate communication within cells. As enzymes, kinases are promising candidates to target for cancer therapy and as such, by identifying interactions between kinases and chemotherapeutic drugs the treatment for cancer could be improved. A research team, led by CeMM PI Joanna Loizou, together with colleagues from the Francis Crick Institute and King´s College, London has now established a catalog of the human kinome in response to different types of genotoxic stress.

Chemotherapy is one of the standard treatments for cancer, and one of the main challenges in cancer treatment is to find means of causing maximum damage to cancer cells with minimum damage to normal cells, by identifying specific cancer vulnerabilities. A group of proteins known to play an important role in the DNA damage response is kinases. Indeed, many kinases are mutated in a variety of human cancers. However, when taken as a whole, it is apparent that the large majority of kinases are understudied. In their recent study, first author Michel Owusu, former PhD Student in Joanna Loizou´s group, and his colleagues, focused on inactivating mutations in kinases generated by CRISPR-Cas9.

By inactivating all possible kinases in human cells and treating them with different types of DNA damaging chemotherapeutic drugs they uncovered vulnerabilities to certain types of DNA damage. This is particularly important for genes such as MARK3 or EPHB6, which are less characterized and yet commonly inactivated in the development of cancer.

In addition, the researchers characterized the effect of selected chemotherapeutic drugs on cancer cells in regards to growth, death, cell cycle and DNA damage. They revealed that within cells, MARK3 mediated communication after DNA damage. In the absence of MARK3, this communication was disrupted, leading to increased death of cancer cells after treatment with DNA damaging chemotherapeutic drugs. Thus, MARK3 is a potential novel biomarker in the treatment of cancer.

How cancer becomes transmissible in Tasmanian devils: molecular mechanisms elucidated

Kosack et al., 2019, Cancer Cell 35, 1-5, January 14, 2019 © 2018 Published by Elsevier Inc. DOI: 10.1016/j.ccell.2018.11.018.

Facial tumors of Tasmanian devils belong to the extremely rare cases of transmissible cancers. Nevertheless, they are highly interesting for biomedical research, as they allow the study of fundamental properties of cancer cells and their interaction with the host´s immune system. Scientists at CeMM, the Vienna University of Veterinary Medicine, the Medical University of Vienna and the LBI for Cancer Research were able to elucidate key molecular mechanisms that are crucial for the transmissibility of the tumor cells. The study „The ERBB-STAT3 Axis Drives Tasmanian Devil Facial Tumor Disease” was published in Cancer Cell, on 14 January 2019, DOI: 10.1016/j.ccell.2018.11.018.

Tumors usually grow exclusively in the organism where their cell of origin derives from. The same applies for human cancers: apart from some rare cases, like the accidental transmission by a cut during surgery, there a no reports on contagious cancer cells. A multitude of molecular safety measures of the immune system is responsible for rejecting and destroying any foreign tissue.

An exception to this nearly universal rule exists among Tasmanian devils, the world’s largest living carnivorous marsupial. Since two decades, a deadly facial tumor is spreading at a rapid pace among the animals that killed according to current estimates around 90 percent of the wild population. Peculiarly, the cancer cells are transmitted from one Tasmanian devil to the other by bites. All collected tumor samples are genetically nearly identical and derive presumably from a single cell of origin.

How this cancer became transmissible and by what means it escapes the immune system of its otherwise healthy hosts puzzled scientists since the discovery of the mysterious disease. The scientists found that receptor molecules on the surface of the cancer cells, so-called ERBB receptors, show massively increased activity. Those receptors trigger a biochemical chain reaction within the cells that eventually activates STAT3 proteins, transcription factors that alter the cell’s genetic program. The result is an extensive rebuild of the cell: The number of molecules serving as identification for the immune system are reduced, while at the same time proliferation is accelerated and factors for metastasis of the tumor cells are produced.

9th S.M.A.R.T. Lecture held by Professor Wolfgang Lutz

Population trends and the global sustainable development goals

The 9th S.M.A.R.T. Lecture held by Professor Wolfgang Lutz, Founding Director of the Wittgenstein Centre for Demography and Global Human Capital (IIASA, VID/ÖAW, WU), was a plea for education. Particularly female education not only connects to a decrease of child mortality and to an increase of life expectancy, it proves to be key to the alleviation of poverty.

In his talk, Wolfgang Lutz proclaimed that essentially people are not very different all over the world. However, we face a universal development of “demographic modernization” with countries currently at different stages of the same process: In the first stage falling death rates due to better sanitation and medical advance together with a culturally determined high birth rate result in a high population growth. In a later stage of development birth rates also fall, leading to low or even negative population growth. By the examples of the demographic transition of Finland from 1722-2017, birth and death rates at Mauritius from 1875 on, and a study on the effect of income or education on the infant mortality in India Wolfgang Lutz impressively showed the effect of education on a higher life expectancy: When it comes to survival, mind matters more than money!

Empirical studies show that the most transformative social changes are associated with the spread of universal female literacy, and the future of world population growth and adaptive capacity to environmental change will crucially depend on female education. The “homo sapiens literata” (MPI-EVA, McElreath) - a sub-species of homo sapiens characterized by high abstraction, literacy, codified knowledge, complex socio-economic institutions and modern science - makes the change. A lively discussion followed the talk, which will continue at CeMM: How can we contribute to a positive societal development? Education matters!

We thank Professor Lutz for his inspiring talk within the S.M.A.R.T. lecture series at CeMM!

CeMM position on genome editing in the light of recent reports about gene-edited babies

Following internal discussions at CeMM on human genome editing – prompted by recent reports on the birth of gene-edited babies using CRISPR technology in China – we distance ourselves from human trials performed without adequate ethical approval by the responsible institutions and in violation of both local regulations and the international consensus in the scientific community.

CeMM welcomes responsible research on understanding and advancing genome editing technology including CRISPR, which greatly benefits basic biomedical research and has great potential also for the treatment of many genetic diseases. Importantly, any such research must be performed in strict concordance with local, national, and international laws and regulations. Furthermore, it should be discussed and supported by the international scientific community, including biologists and medical researchers as well as ethicists, social scientists and various stakeholders of civil society, such as patients’ organizations.

There is broad consensus within the scientific community that editing of the human germline for human enhancement is entirely unacceptable. In contrast, genome editing to correct severe genetic diseases may be acceptable if there is a clear positive risk-benefit ratio, no suitable alternatives, comprehensive preparatory work supporting feasibility, full legal and regulatory compliance, and strong framework of ethical guidance and supervision.

CeMM is committed to participate in a broad societal dialog about CRISPR technology, genome editing, and other developments in the life sciences. It is important that these developments are not happening in perceived or actual secrecy at highly specialized research institutions, but that they are part of a broad discussion about chances and risks, and based on information, education and divulgation on all scientific, medical, ethical and societal aspects associated. CeMM is committed in fostering this debate and promoting genetic literacy in the general population.

Kaan Boztug, Director of the Ludwig Boltzmann Institute for Rare and Undiagnosed Diseases (LBI-RUD), is awarded a prestigious Consolidator Grant of the European Research Council (ERC) for research on human immune dysregulation.

Kaan Boztug, Director of the Ludwig Boltzmann Institute for Rare and Undiagnosed Diseases (LBI-RUD), Adjunct PI at CeMM and Professor of Pediatrics at the Medical University of Vienna and St. Anna Children’s Hospital, receives the renowned funding by the ERC with a project duration of five years to decode disorders of the human immune regulation. After being granted a FWF START prize and an ERC Starting Grant in 2012, Kaan Boztug’s research is now funded for the second time by the ERC. This shows recognition of the excellent work of Prof. Boztug’s research group, who is regarded as an international expert in the field of rare diseases of the immune system and hematopoiesis.

Why does the human body attack itself sometimes? What causes problems in the regulation of the immune system? And why are these disorders often leading to cancer? How can these insights be used to develop targeted therapies in the future? Kaan Boztug and his team try to answer these questions. The goal is to identify novel genetic factors for autoimmune disorders – diseases where the body is not able to distinguish between the body’s own cells and cells of invading pathogens. Kaan Boztug hypothesizes that the number of pathways involved is finite: “My goal is to create a map showing as many genes and pathways as possible that play a role in disorders of the balance of the immune system. This marks the foundation of further research activities and will lead to starting points for novel therapies.”

ERC Consolidator Grant
Project funding by the European Research Council (ERC) ranks among the most prestigious fundings within Europe. The Consolidator Grants are awarded up to two million euros and are intended to support excellent researchers by securing their independence and developing a successful career path. Kaan Boztug’s Consolidator Grant is already the 10th funding by the ERC for (Adjunct) PIs at CeMM.

The Ludwig Boltzmann Institute for Rare and Undiagnosed Diseases (LBI-RUD) was launched by the Ludwig Boltzmann Gesellschaft in April 2016 together with its partner institutions including the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences, the Medical University of Vienna and the Children’s Cancer Research Institute and the St Anna Children’s Hospital Vienna. Its research remit is the thorough analysis of rare diseases of the hematopoietic system, the immune system and the nervous system – as such not only dedicated to provide research for the development of personalized therapeutics for affected patients, but with similar efforts dedicated to unravel novel insights into human biology. Benefitting from full access to the infrastructure of its partner institutions, LBI-RUD has established a coordinated research programme, integrating and considering scientific, sociologic, ethical and economical aspects of rare diseases. www.rare-diseases.at

We congratulate Kaan Boztug and his team!

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.
