We explore the universe of RNA, not just as a messenger of genetic blueprints but as a dynamic entity that shapes life at the molecular level. Our work treats RNA as a puzzle, where each piece is a clue to its myriad roles from catalysts to regulators within the cell. With advanced computational models and experimental techniques, we decode RNA's complex structures and interactions, especially with proteins and small molecules.
Research Summary
Our work is focused on the development and applications of new methods for RNA structure determination and modeling RNA interactions, combining computational predictions with experimental analyses. This approach is vital for delving into RNA's role in biological processes, contributing significantly to the fields of molecular biology, bioinformatics, and structural biology. Our contributions include software tools like ModeRNA and SimRNA, which have become essential for researchers globally. We investigate the three-dimensional structures of RNA from viruses, bacteria, and humans, focusing on potential targets for small molecules. Our research is enriched by interdisciplinary collaborations with various research groups and with commercial partners in Poland and worldwide.
Scientific Impact
- Tools for RNA modeling & small molecule interactions
- Determined structures of viral & bacterial RNAs (e.g., coronavirus 5' regions)
- Collaborated with Molecure to validate tools in drug discovery (inhibiting cancer protein translation)
Future Goals
We aim to deepen our understanding of RNA structure and function, particularly by studying molecules with therapeutic potential. Our advances in computational methods, integrated with experimental studies, are geared towards contributing to both fundamental research and future practical applications, with the ultimate goal of positively impacting scientific knowledge and human health.

We study molecular processes, which degenerate neurons in Alzheimer’s (AD), Parkinson’s (PD) and Huntington’s (HD) diseases. We use cultured human and animal cells as well as fish and mouse models of these diseases. Recently we have shown that the disappearance of neurons in the PD zebrafish model can be stopped by inhibiting the influx of calcium ions to mitochondria. We plan to identify calcium sensitive proteins that take part in the development of this disease.
Research Summary
Parkinson disease (PD) is an incurable neurodegenerative disorder. Its pathological hallmarks include the aggregation of α-synuclein and loss of dopaminergic neurons. In various PD animal models and in cells from PD patients, perturbations of calcium homeostasis occur. Our major focus are on Ca2+ dependent mechanisms involved in the development of PD. Its three types can be distinguished: most prevalent sporadic with a late onset, familial that is caused by mutations of genes such as PINK1 or LRRK2, and environmentally-induced by drugs such as MPTP. Our published data show that degeneration of dopaminergic neurons in zebrafish PD models as a result of a pink1 mutation or MPTP toxicity is rescued by inactivation of the mitochondrial calcium uniporter (MCU). Others showed that MCU inhibition rescues neurons with mutation in LRRK2. If different factors that cause PD have a common denominator that is related to MCU activity, then what is it? Our hypothesis is that specific genes are turned on or off when MCU inactivation exhibits protection of dopaminergic neurons. The aim of our work is to identify those genes, proteins and cells in which they are expressed to understand how they provide neuronal protection.
Scientific Impact
- We expect to identify genes that are turned on or off when calcium ions cannot enter mitochondria via uniporter.
- We will identify cells in which proteins that are encoded by these genes operate.
- The identified genes and proteins might have potential diagnostic value for pre-symptomatic stages of PD and provide a basis for novel anti-PD treatments.
Future Goals
After identifying gene(s) that are turned on or off when calcium ions cannot enter mitochondria via their uniporter and cells in which it takes place to preserve neuronal protection, the goal will be to confirm this mechanism in animal models such as zebrafish.
Comment
"In various animal models of Parkinson’s (PD), as well as of Alzheimer’s (AD) and Huntington’s (HD) diseases and in cells from PD, AD and HD patients, perturbations of calcium homeostasis occur. Studying these processes may identify common pathological mechanism in neurodegenerative diseases", says Prof. Jacek Kuźnicki.

We study epigenetics, i.e. nucleic acid and histone modifications that control cell fate change and maintenance. Our methods range from various flavors of high-throughput sequencing to classical biochemistry and structural biology. We also rely increasingly on “big data”. Our work has implications in oncology, particularly for hematologic malignancies that have a strong epigenetic component.
Research Summary
Our work is focused on chromatin modifications, and on their role in maintaining and changing cell fate. Most of our projects revolve around DNA modifications, particularly DNA maintenance methylation at the replisome, and its reversal by active and active- passive DNA demethylation. We study the links between "epigenetic" and "repair" enzymes, as well as the recruitment and adaptation of DNA repair processes to epigenetic reprogramming. We are also interested in the contributions of histone modifications to cell fate maintenance and change. Specifically, we are investigating COMPASS- like complexes - the mediators of positive genetic memory.
Scientific Impact
- We have contributed to a better understanding of TET dioxygenases that are the drivers of active and active-passive DNA demethylation.
- We have helped to elucidate the feedback loop that implements positive genetic memory.
- We have discovered and classified a number of reader domains for nucleic acid modifications.
- We have elucidated a chemically novel nucleic acid modification pathway.
Future Goals
In the future, we plan to extend our chromatin studies, taking into account preventive epigenome maintenance by nucleotide pool control. We want to focus on "epigenome repair" mechanisms that counteract gradual epigenome degradation with age and in disease. Furthermore, we want to better understand how the loss of enzymes with antagonistic roles (DNMT3A, TET2) can have similar, malignancy-promoting effects in cancers with a strong epigenetic component.
Collaborations
Our collaborators come from both academia (e.g. G. Xu, J. Wong, T. Jurkowski, T. Hore, C. Winata, W. Bickmore, A. Wlodawer) and the biotech industry (S. Xu, P. Weigele). Thanks to this strong circle of partners, we have extended our research methods spectrum and we can now ask questions at very different levels, ranging from atomistic to animal studies.
Comment
"With minor exceptions, all cells in our body carry the same genetic information and yet they are very different. Much of the difference is epigenetically encoded in the form of DNA and histone modifications. We combine genetics, biochemistry and structural biology to study the maintenance and remodeling of the epigenetic layer of our genomes", says Prof. Matthias Bochtler.

The lab works on epigenetic marks on DNA and histones and their effects on cell fate maintenance and change. The picture is an “artistic” representation of the theme of the lab, prepared using generative artificial intelligence.

We study how cells take up and transport various substances within their interior, focusing on how these logistical rules are altered in cancer cells to support their uncontrolled growth. By understanding the differences in cellular functioning between normal and cancerous cells, we aim to guide the development of therapies that selectively target and eliminate cancer cells. We have already identified one such vulnerability, an “Achilles’ heel,” in certain cancer cells and continue our search for additional therapeutic targets.
Research Summary
We are fascinated by two intracellular processes, endocytosis and receptor signaling, and how they are interlinked. We seek to understand how endosomal compartments contribute to the trafficking and signaling of receptors for growth factors and cytokines in normal and cancer cells.
We investigate the roles of endosomal sorting complexes required for transport (ESCRT) in cell physiology and oncogenesis. Our research has revealed that the dysfunction of endosomes caused by the absence of proper ESCRT function induces an intracellular sterile inflammatory reaction.
We also found out that the ESCRT-I complex is indispensable for the biogenesis and proper functioning of lysosomes, as well as energy metabolism in the cell.
The synthetic lethality we identified between two paralogous ATPases of the ESCRT machinery, VPS4A and VPS4B, revealed a novel pair of druggable targets for personalized oncology.
In another line of research, we focus on the receptor tyrosine kinase AXL, which is overexpressed in late-stage cancers. By identifying the interactome of AXL, we revealed that its activation induces several actin-dependent processes, including macropinocytosis.
Scientific Impact
Our studies provide proof of concept that intracellular trafficking and the molecules regulating it can represent a viable therapeutic target in personalized oncology. For example, the synthetic lethality between VPS4A and VPS4B ATPases provides a rationale for developing VPS4 inhibitors for the precision treatment of VPS4B-deficient cancers. Our ongoing studies of AXL-dependent macropinocytosis aim to uncover ways of blocking this process in metastatic and drug-resistant cancers with AXL overexpression.
Future Goals
We wish to understand how altered expression or mutations in the ESCRT components, observed in cancer or some rare diseases, modify cell physiology. In parallel, we aim to elucidate the mechanisms and effector proteins by which the activated AXL receptor drives macropinocytosis in cancer cells.
Collaborations
We collaborate with partners from the IIMCB and external institutions within the HERO consortium project, which aims to develop the next generation of mRNA-based cancer immunotherapies.
Comment
“We study alterations that occur in signaling and trafficking processes in cancer cells because such changes may represent vulnerabilities of cancer cells to specific therapies”, says Prof. Marta Miączyńska

Our goal is to understand how nerve cells develop their characteristic shape, critical for the functioning of the brain. Our "gateway" to the world of neurons is the protein mTOR. By utilizing molecular and cellular biology tools, we have come to understand what functions of mTOR are essential for neurons. We want to use this knowledge to diagnose and treat tuberous sclerosis, a disease caused by excessive mTOR activity.
Research Summary
Since the inception of our laboratory, our goal has been to understand how neurons develop their characteristic shape, which is crucial for brain function. We have sought to identify such mechanisms by studying the mammalian/mechanistic target of rapamycin (mTOR) protein, which is involved in neuronal development and various neuropathologies known as mTORopathies. mTOR is a serine-threonine kinase involved in almost all aspects of mammalian cell function. It forms two protein complexes that were originally thought to regulate translation (mTORC1) or affect the actin cytoskeleton (mTORC2). My postdoctoral work showed that regulating mTOR-dependent translation contributes to dendritogenesis. However, our subsequent work has shown that mTOR functions during neuronal development go beyond the canonical control of translation, e.g., cytoskeleton regulation, intracellular transport or transcription. Our recent studies focus mainly on mTOR functions in neuronal nuclei. An essential part of our work has been to apply our findings in cellular models to clinically relevant models and material. We focused on tuberous sclerosis (TSC), a disease caused by hyperactive mTOR. As a result, we have identified new potential drug targets (TrkB, GCLC) and predictive biomarkers for epilepsy in TSC. In parallel, in recent years we have investigated the mechanisms underlying the stability of neuronal morphology associated with the development of depression.
Scientific Impact
- Discovery of numerous regulators of neuronal cell morphology, including several mTOR substrates.
- Identification of GCLC and TrkB as new potential therapeutic targets in tuberous sclerosis.
- Development of predictive biomarkers for drug-resistant epilepsy in children with tuberous sclerosis.
Future Goals
Our primary goal for the coming years is to find out what functions mTOR fulfills in the nucleus of neurons and how they affect their proper development and function. Our current research suggests that destabilizing nuclear mTOR functions, such as controlling transcription factors, can lead to epilepsy. Therefore, we want to test this hypothesis thoroughly.
Collaborations
Our key collaborators include Prof. Kathrin Thedieck, Prof. Sergiusz Jóźwiak, Prof. Katarzyna Kotulska, Prof. David Kwiatkowski, Prof. Eleonora Aronica, Prof. Leszek Kaczmarek and Prof. Ewelina Knapska. We are working to understand how molecular biology translates into clinical features of tuberous sclerosis or depression and how this knowledge can be used to help patients.
Comment
"Our research focuses on the molecular basis of the development and stability of neuronal networks. In particular, we focus on the molecular functions of the mTOR protein, which will enable better diagnosis and potential therapy of mTORopathies, diseases caused by mTOR hyperactivity", says Prof. Jacek Jaworski.
