Frankfurt physicians successfully test leukemia-specific therapy in preclinical study

Oncology: Fighting leukemia with therapeutic RNA

Each year, around 13,000 people in Germany are diagnosed with leukemia, of which up to half die from the disease despite intensive chemotherapy. Beyond that, therapies have severe side effects: In particular, they inhibit the formation of normal blood cells. In a preclinical study, a team from the Department of Pediatrics at Goethe University Frankfurt has tested a novel therapy based on a therapeutic RNA. Through the treatment, the laboratory animals survived significantly longer than their untreated counterparts. The hope now is that this leukemia-specific therapy will be able to support existing chemotherapies in the future. 

Each year, about 13,000 people in Deutschland are diagnosed with leukemia, an umbrella term that encompasses various forms of blood cancer. Among those affected are also many children and adolescents under 15 years of age. A common and very aggressive form of leukemia in adults is acute myeloid leukemia (AML). In AML, blood cells in the early stages – the stem cells and the precursor cells that develop out of them – transform. AML is the second most common form of leukemia in children, accounting for around four percent of all malignant diseases in childhood and adolescence. Despite treatment with intensive chemotherapy, only between 20 and 50 percent survive the first five years after diagnosis and treatment; half or more relapse and die. Furthermore, these intensive therapies have severe side effects: In particular, they damage the stem cells that form new blood. There is therefore an urgent need to develop new therapies tailored specifically to AML. 

Researchers led by Professor Jan-Henning Klusmann from the Department of Pediatrics and Professor Dirk Heckl from the Institute for Experimental Pediatric Hematology and Oncology at Goethe University Frankfurt have now tested such a leukemia-specific therapy in animal experiments. They used a therapeutic RNA molecule packaged in lipid nanoparticles to treat animals with leukemia. “By packaging it in lipid nanoparticles, we have in principle applied the same technique that was used for COVID-19 immunization," explains Klusmann. “The lipid nanoparticles transport the therapeutic RNA into the blood cells." 

The therapeutic RNA miR-193b was already described in 2018 as having a protective effect against cancer. In healthy cells, miR-193b slows down signaling pathways that are only activated for cell proliferation and which the stem cell otherwise hardly uses. That is why miR-193b is referred to as a tumor suppressor. In AML cells, however, miR-193b is not present in sufficient amounts and therefore unable to fulfil its task as a tumor suppressor. “Scientists have been testing active substances for many years that act as inhibitors and intervene in these signaling pathways used by AML cells," says Heckl. “The problem is that such substances only ever attack one component, whereas miR-193b acts on all levels of the signaling pathway. This stops the division of the abnormal cells very efficiently and causes the leukemia cells to die off quickly." Another advantage of therapeutic RNAs is that they do not damage the stem cells of the hematopoietic system, unlike conventional chemotherapies, because they are not dependent on the suppressed signaling pathways. 

All the laboratory animals tolerated the treatment with the nanoparticles containing the active substance well, and the leukemia cells were successfully fought off, as Klusmann summarizes: “We were able to significantly extend survival time in all the animals we treated, and some were even cured." What is particularly encouraging is that miR-193b worked in all the AML subtypes tested: The scientists examined four different types of cancer cells in their trials, including one common in people with Down syndrome. “In the past, noncoding RNAs and their genes were regarded as junk DNA," explains Klusmann. “Now we have developed a therapy based on this 'junk' that promises a new and very specific treatment option for myeloid leukemia." The hope is that this therapy can support chemotherapies in the future so that they do not have to be so intensive.

German Research Foundation makes available more than €7 million in funding for research training group focused on housing research 

"Habitual change": On changes in housing and society 

Society is changing and housing with it. A joint research training group of Goethe University Frankfurt and Bauhaus-Universität Weimar will investigate this connection scientifically. 

Goethe University Frankfurt and Bauhaus-Universität Weimar have secured more than €7 million in funding from the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) for the joint research training group on "Societal Transformation and Spatial Materialization of Housing". Starting in fall 2024, young researchers at Weimar and Frankfurt will conduct interdisciplinary research on the current housing provision. 

Housing is a basic human need and fundamentally important to both individual and social development. It also reflects epochal upheavals and processes of social change. Creating more socially just housing is a central and major challenge of contemporary urban development. 

Given that tomorrow's built environment is shaped by today's social developments, the research training group focuses on changes in the living environment caused by social conflicts, ecological demands or digitalization processes, asking, for example, what challenges, problems, contradictions and conflicts this poses for housing. And how does this built-up living environment in turn influence future social developments, or how should it shape them? 

Sebastian Schipper, who is the research training group's deputy spokesperson and Professor of Geographical Urban Research at Goethe University Frankfurt, explains: "The work being produced by the group will focus on the tense relationship between social transformation and the built-up residential environment. The aim is to develop research perspectives with which questions of housing, its transformation and its future can be systematically researched from a social and structural-spatial perspective." 

The research training group brings together specialist expertise from Goethe University Frankfurt and Bauhaus-Universität Weimar: On the one hand, the consortium includes experts from Weimar, who take a planning and engineering or design-related perspective on housing, and, on the other, professors from Frankfurt, who research housing primarily from a social science and humanities perspective. 

Up to 36 doctoral theses on housing issues can be completed over the entire nine-year funding period. For the research training group's first, five-year funding phase, Bauhaus-Universität Weimar and Goethe University Frankfurt will receive a total of €7.2 million from the DFG. As the main applicant, Bauhaus-Universität Weimar will initially act as the group's spokesperson. The other cooperation partners are Darmstadt-based Institute for Housing and Environment – Institut Wohnen und Umwelt GmbH (IWU), Frankfurt University of Applied Sciences (UAS), Klassik-Stiftung Weimar, Stiftung Baukultur Thüringen and Bundesverband für Wohnen und Stadtentwicklung e.V. (federal association for housing and urban development).

Plans to conduct further research into a new pathway of the cellular recycling system (autophagy)

Biochemist Christian Münch from Goethe University Frankfurt receives ERC Consolidator Grant

Dr. Christian Münch from Goethe University Frankfurt's Institute of Biochemistry II has been awarded the European Research Council's (ERC) prestigious Consolidator Grant to conduct further research into a mechanism he discovered, which the cell uses to operate its recycling system. The research funding consists of two million euros provided over the next five years. The mechanism, which Münch has named "autoxitus", could serve as a novel communication pathway between neighboring cells and play a role in viral infections and neurodegenerative diseases. 

Congratulating the biochemist, Goethe University President Prof. Enrico Schleiff said: "Dr. Christian Münch is an outstanding scientist, who has now succeeded for the second time in asserting himself in the highly competitive ERC grant selection process. As in the past, his research project on 'autoxitus', too, will yield fundamental and groundbreaking insights into the interplay between metabolism and signaling in the cell. That is because with his program, Münch demonstrates the courage to take scientific risks – something we at Goethe University greatly appreciate and encourage, because such projects truly advance our knowledge, and thereby constitute the absolutely necessary prerequisite for innovation and transfer. This ERC grant once again illustrates just how successful we are in attracting excellent young talent to Goethe University." 

As part of his new research project, Dr. Christian Münch is investigating a new type of degradation process through which the cell maintains a finely tuned balance for its constant synthesis of diverse substances and organelles. As part of the so-called autophagy, the cell encloses components that are no longer required with membrane vesicles, within which these components are broken down. However, as part of the "autoxitus" degradation pathway discovered by Münch, the contents of these membrane vesicles are transported out of the cell. One of Münch's research questions is whether the cell can use this to signal to its neighbors that it is in a state of stress, caused, for example, by a viral infection or a neurodegenerative disease. 

Christian Münch completed his doctorate at the University of Cambridge and worked as a postdoctoral researcher at Harvard Medical School. He has served as head of the Department of Quantitative Proteomics at Goethe University Frankfurt's Institute of Biochemistry II since 2016. His research focuses on cellular stress responses to misfolded proteins in the cell's power plants (mitochondria) as well as on infections and diseases, all with a view towards understanding how the entire cell system reacts to stress. For his work, he has already received an ERC Starting Grant, an Emmy Noether grant and a number of awards. Münch is an EMBO Young Investigator and a steering committee member in the Federal Ministry of Education and Research's Cluster4Future Proxidrugs, the Collaborative Research Center 1177 on selective autophagy, the Fraunhofer High-Performance Center TheraNova, and the Goethe University-led EMTHERA (Emerging Therapeutics) research cluster initiative. 

The European Research Council's ERC Consolidator Grant supports excellent, promising scientists whose working group is in the consolidation phase. The grant is intended to enable them to expand their own field of research and conduct visionary, basic research. With a funding volume of up to two million euros for five years, the Consolidator Grant is one of the most highly endowed individual funding measures in the European Union.

In the DNA of leukemia cells, physicians from Goethe University Frankfurt have identified a promising target for new therapeutic approaches.

Pediatric oncology: Scientists discover new Achilles heel of leukemia cells 

Leukemia is the most common type of cancer in children. Treatment involves intensive chemotherapy, which has severe side effects due to its non-specific mode of action. A team from the Department of Pediatrics and the Institute for Experimental Pediatric Hematology and Oncology at Goethe University Frankfurt has now discovered a site in the DNA of cancer cells that is essential for leukemia cells to survive. Cancer cells in which the gene encoded at this site was modified experimentally died off. The gene locus thus constitutes a promising target for an alternative therapy in the future. 

The term 'leukemia' encompasses various forms of blood cancer, including acute myeloid leukemia (AML). In AML, blood cells in the early stages – the stem cells and the precursor cells that develop out of them – degenerate. AML is the second most common leukemia in children, accounting for around four percent of all malignant diseases in childhood and adolescence. Despite intensive chemotherapy, only around half of those affected survive without relapsing. About one third of children are dependent on a stem cell donation. Since non-specific chemotherapies have severe side effects, there is an urgent need to find new and specific therapy approaches. 

A team led by Jan-Henning Klusmann from the Department of Pediatrics and Dirk Heckl from the Institute for Experimental Pediatric Hematology and Oncology at Goethe University Frankfurt has now discovered an unusual “Achilles heel" in AML cells. For their study, which has now been published, they looked at a specific group of nucleic acids in leukemia cells: noncoding RNAs. Just like regular messenger RNAs (mRNAs), these are produced through gene transcription. However, unlike mRNAs, noncoding RNAs are not translated into proteins but instead often assume regulatory functions, for example in cell growth and cell division. A typical characteristic of cancer cells is a massive disruption of regulatory processes. This makes noncoding RNAs an interesting starting point in the fight against cancer. 

Against this background, the researchers led by Klusmann and Heckl wanted to know more about the role of noncoding RNAs in AML cells. For this purpose, they compiled a kind of inventory of these molecules in cancer cells taken from sick children and compared the resulting pattern with that of healthy blood stem cells. AML cells differentially expressed almost 500 noncoding RNAs in comparison to healthy cells – an indication that they could perform an important function in cancer cells. To validate this, the researchers turned off every single one of these RNA molecules by preventing the coding gene in the genome from being read. The most distinct effect they found was for the gene MYNRL15: Cancer cells in which this gene was turned off lost their ability to replicate indefinitely and died off. 

Surprisingly, however, it was not the absence of noncoding RNAs that was responsible for this effect, as Klusmann comments: “The regulatory function we observed is due to the MYNRL15 gene itself." The team was able to show that destroying the gene altered the spatial organization of the chromatin, i.e. the three-dimensional structure of the genome. “This led to the deactivation of genes that AML cells need for survival," says Klusmann. This offers a new and unforeseen possibility for fighting leukemia. 

What is significant against this background is the fact that the inhibitory effect triggered by the modified MYNRL15 gene could be observed in different AML cell lines. These cells originated both from children as well as adults and included various subtypes of the disease – among them one common in people with Down syndrome. “The fact that all the leukemias we studied were dependent on this gene locus tells us it must be important," concludes Klusmann. The researchers now hope that the cancer cells' dependence on MYNRL15 can be used to develop a specific gene therapy. “In our study, we systematically examined noncoding RNAs and their genes in AML cells for the first time, and in the process we identified a gene locus that constitutes a promising target for developing a therapy in the future," says Klusmann, summing up.

New record for lead ion collisions at CERN: Highest energy and highest collision rate – Goethe University physicists and computer scientists involved in data collection and analysis

Tiny Big Bang: ALICE experiment restarts with lead ions – Goethe University Frankfurt helped set new measurement record

After a five-year break, the large LHC accelerator at the CERN international research institute has once again brought lead ions to collision. During the process, the colliding matter dissolves into its components for an extremely short time, reaching a state like the one that prevailed in the universe a few millionths of a second after the Big Bang. The particle tracks of these collisions are recorded by the house-sized ALICE detector, which Goethe University researchers helped upgrade. Already during the first month of the new data collection period, a new record was set: 20 times more collision events were registered than in the data-taking periods of previous years combined. 

On September 26, 2023, the accelerator team at the CERN European Council for Nuclear Research in Geneva declared stable lead-beam conditions, ushering in the first data-taking campaign of lead-ion collisions in five years. From then until the late evening of October 29, the accelerator produced lead-ion collisions at the world's highest-ever collision energy of 5.36 terra electron volts per colliding nuclear particle (nucleon-nucleon collision). In addition to the collision energy, the collision rates also increased significantly compared to the data taking periods of previous years. The ALICE detector, specialized in recording lead atomic nucleus collisions, recorded 20 times more events than in the previous four data-taking periods combined – each of which lasted about one month, and the first of which dates back to 2010. 

This is important because of the tremendous number of particles that are created and decay in a very short timeframe during the collisions. Recording the tracks of these particles allows conclusions to be drawn about exactly what happens at the moment of collision and shortly thereafter: The particles dissolve into their elementary components – quarks and gluons – and form a kind of "matter soup", a so-called quark-gluon plasma. Immediately afterwards, new, very unstable particles form again, which finally transform into stable particles in complex decay chains. In this way, researchers in the ALICE experiment are studying the properties of matter as it existed shortly after the Big Bang. 

Research groups from Goethe University Frankfurt are part of the experiments: The new record was first made possible because the world's most powerful particle accelerator, the Large Hadron Collider (LHC), was upgraded during the four-year reconstruction phase from 2018 to 2022. The upgrades of the ALICE detector during the same timeframe enable it to record the traces of the LHC's higher collision rates. 

To carry out these upgrades, it was necessary to replace the readout detectors of the experiment's central detector, the so-called Time Projection Chamber (TPC). Professor Harald Appelshäuser from Goethe University's Institute for Nuclear Physics Frankfurt (IKF) serves as project lead for this 10-year undertaking. 

The enormous amount of data generated during the measurements – which reaches the range of terabytes per second for the TPC alone – constitutes a major challenge. To be able to sufficiently reduce the amount of data stored, this data stream must be processed in real time, using effective pattern recognition methods. The Event Processing Nodes (EPN) computing cluster was set up specifically for this experiment. Based on both conventional computing cores (CPUs) and special graphics processors, the EPN project is led by Volker Lindenstruth, Professor for High-Performance Computer Architecture at Goethe University and Fellow at the Frankfurt Institute for Advanced Studies (FIAS). 

The measurements at higher collision rates are a major success for CERN's heavy ion program. Prof. Appelshäuser: "It's finally happening! We have been working towards this for 10 years, and are looking forward to evaluating the data we have now obtained. I would especially like to thank Germany's Federal Ministry of Education and Research for its long-term funding, not least since the only way for research projects of this dimension to be successful is by having such a reliable partner on board."
