SUMMARY:IDP – Image Data Presentation
DESCRIPTION:The human eye is our primary tool for interpreting images\, so scientific images should be adjusted with this perception in mind. However\, display and print transfer characteristics often degrade images\, making them differ from reality. This course offers a unique approach\, focusing on preparing image data for presentation. \nWe’ll cover essential topics like gamma correction and print preparation to ensure your posters and figures appear as true-to-life as possible. \nDay 1: Lectures with scientific colleagues and the opportunity to consult with top experts in advanced graphic displays (Antonin Charvat\, EIZO) and professional photo preparation for print (Karel Pones\, ITF). \nDay 2: Hands-on practice with image processing software and figure-making techniques (Adobe CS and freeware alternatives). \nYou’re welcome to attend the lectures without registration\, but registration is required for the practical sessions. \nWe look forward to seeing you! \nThe Organizing Team \n Oldrich Benada\, MBU & Ivan Novotny\, IMG

SUMMARY:Seminář Nenad Radivojević\, M.Sc.
DESCRIPTION:“Quality control in snRNP biogenesis” \nBefore being assembled into spliceosomes\, small nuclear ribonucleoprotein particles (snRNPs) undergo a complex and regulated maturation pathway. Cajal bodies (CBs) have been shown to monitor the final stage of this process by sequestering immature or misassembled particles through a yet unknown quality control mechanism. Here\, we have identified coilin\, a CB marker protein\, as the quality control factor. We further characterize coilin domains interacting with snRNPs and elucidate the molecular mechanism how coilin recognize immature snRNPs. \n

SUMMARY:Lecture „Unlocking the secrets of the heart – toward an understanding of molecular sex differences in cardiac health and disease“
DESCRIPTION:Lukáš Chmátal\, Ph.D.\, Whitehead Institute for Biomedical Research\, MIT\, USA \nHeart disease is the leading cause of death worldwide\, but its effects are far from uniform. Men and women experience striking differences in symptoms\, prevalence\, and outcomes – yet the molecular mechanisms underlying these differences remain poorly understood. In this lecture\, I will reveal how male and female hearts fundamentally differ in their energy metabolism\, which is driven by mitochondria\, the cell’s powerhouse. I will also outline innovative experimental approaches to uncover the role of sex chromosomes in regulating these differences – insights that will shape the research agenda of my own laboratory. Please\, join me to explore how understanding these mechanisms could transform the way we approach cardiac health for both sexes. \nMore: https://fgu.cas.cz/udalost/lukas-chmatal-ph-d/

SUMMARY:Seminář Karolina Kowalska\, M.Sc.
DESCRIPTION:“Structural basis of MICAL autoinhibition and activation” \nIn this talk\, we will explore the role of MICAL proteins in cellular dynamics\, focusing on their ability to disassemble actin filaments and their implications for processes like axon guidance\, cytokinesis\, and cell morphology. We will present our recent findings based on the cryoEM structure of human MICAL1\, which reveal the molecular mechanisms underlying MICAL1 autoinhibition. Specifically\, we will discuss how an intramolecular interaction between the N-terminal catalytic and C-terminal coiled-coil domains blocks F-actin interaction\, and how structural changes and domain interactions mediate activation. These findings highlight evolutionarily conserved mechanisms within the MICAL family\, shedding light on their broader functional relevance.

SUMMARY:Seminář Dr. Nicolas Rivron
DESCRIPTION:Modeling human early pregnancy with stem cells” \nThe blastocyst is the early mammalian organism before implantation in the uterus. We have promoted the self-organization of stem cells into models of mouse and human blastocysts\, which we have named blastoids (Nature 2018\, Nature 2021). Blastoids are morphologically and transcriptionally similar to the blastocyst and contain analogs of all three cell types that would eventually develop into the complete organism (embryonic and extraembryonic). Because blastoids are complete and model the preimplantation stage\, they can be introduced into the uterus (mouse model) or combined in vitro with uterine cells (human model) to recapitulate aspects of the normally hidden implantation processes. Unlike blastocysts\, blastoids come in large numbers and facilitate a more systematic modulation and analysis of development. As such\, they represent both a scientific and ethical alternative to the use of embryos for research. Using this approach\, we are investigating the genome evolution underlying species-specific aspects of blastocyst development and implantation\, with the long-term goal of understanding the evolutionary basis of human pregnancy characteristics (50% of fertilized eggs never develop). This knowledge could help solve the global health problems of family planning\, fertility decline and prenatal preventive medicine.

SUMMARY:Seminář Karolína Vaníčková\, M.Sc.
DESCRIPTION:“Infections and hematopoietic stem cells: how do they communicate?” \nInfections are primarily cleared by immune cells in our bodies. However\, we observed that the most immature hematopoietic stem cells also contribute to this process. In this lecture\, we will report on the mechanisms that activate an hematopoietic stem cell during infection and the cellular adaptations that these cells undertake. Special attention will be given to the contribution of the Wnt/beta-catenin signaling pathway.

SUMMARY:Seminář Michal Mrkáček\, M.Sc.
DESCRIPTION:“Tipping the Lipid Scales: Negative Feedback Regulation via ORMDLs Protein Degradation Ensures Sphingolipid Homeostasis” \nSphingolipids are essential lipid molecules that contribute to cellular structure and signaling. Their de novo synthesis is initiated in the endoplasmic reticulum (ER) and catalyzed by the multimeric serine palmitoyltransferase (SPT) complex. The ER-resident ORMDL proteins are well-established regulators of sphingolipid synthesis\, directly inhibiting the SPT complex to control the pathway at its origin. Here\, we identify a negative feedback loop that fine-tunes this regulatory mechanism. Using pharmacological inhibitors such as myriocin and fumonisin B1\, which target different steps of the sphingolipid pathway\, we demonstrate that reduced sphingolipid levels promote enhanced degradation of ORMDL proteins. This degradation alleviates SPT inhibition\, thereby accelerating de novo sphingolipid biosynthesis and restoring metabolic balance.

SUMMARY:Seminář Mgr. et Mgr. Evžen Bouřa\, Ph.D.
DESCRIPTION:“RNA cap methylation in poxviruses and coronavirus – differences and similarities” \nRNA methyltransferases (MTases) are responsible for synthesizing the 5′ RNA cap\, which plays a crucial role in RNA stability and efficient translation. Over the past two years\, both our research team and others have developed numerous inhibitors targeting coronaviral MTases. Through our efforts\, we have successfully determined the crystal structures of these inhibitors bound to the coronaviral nsp14 and nsp16/nsp10 MTases. Additionally\, we recently elucidated the crystal structure of the monkeypox virus MTase VP39\, in complex with the broad-spectrum MTase inhibitor sinefungin and several other inhibitors. These structural studies have unveiled notable distinctions between coronaviral and poxviral MTases\, while also highlighting the potential for targeting these enzymes with the same or closely related compounds.

SUMMARY:Seminář Lenka Ungrová\, M.Sc.
DESCRIPTION:“Birds do it their way: avian interferon regulatory factors (almost) resolved” \nInterferon regulatory factors (IRFs) are transcription factors that play a key role in vertebrate innate antiviral immunity. IRF3 and IRF7 activate the expression of IFN-β\, which in response induces the assembly of STAT1\, STAT2 and IRF9 into the ISGF3 complex. Subsequently\, this complex activates the expression of interferon-stimulated genes (ISGs) mounting the antiviral state of the cell. Interestingly\, IRF9 and IRF3 have been reported to be missing in birds. As part of our efforts to search for hidden genes in avian genomes\, we have identified IRF3 in paleognathous birds and IRF9 in most bird orders with the notable exception of the chicken. We focus on the experimental characterization of IRF9 in a duck cell line and also look for a possible substitute for IRF9 in chickens.

SUMMARY:Seminář Ludovica Antiga\, M.Sc.
DESCRIPTION:“PIP2-RNA-protein interactions in phase separation of Pol II transcription” \nThe RNA Polymerase II transcription is a multifaceted process crucial for gene expression in eukaryotic cells. Over the last decade\, liquid-liquid phase separation (LLPS) was shown to be crucial in regulation of RNA pol II transcription. We have shown that nuclear phosphoinositides are pivotal for regulating biological processes and PIP2 has been shown to localize with RNA Pol II machinery and nascent RNA\, linking it to the initiation step of transcription. Here\, by using lipid-interacting RNA sequencing (LIPRNAseq) and confocal microscopy\, we found a PIP2-binding AU-rich RNA motif and identified the long non-coding RNA HANR (lncHANR) in complex with PIP2 as a part of oncogenic super-enhancers in perinucleolar region of the nucleus.Furthermore\, we used PIP2-pull down coupled with mass spectrometry to identify RNA-dependent PIP2 interactome associated with nuclear processes emphasizing the role of PIP2 in liquid-liquid phase separation of RNA Pol II transcription machinery. \n

DESCRIPTION:“Analysis of a novel chicken Pax6 mutant” \nPax6 is known as the „master control gene“ for eye formation\, playing a crucial role in the development of the lens\, retina\, and other ocular structures. It drives the formation of the eye field\, initiates lens differentiation\, and helps establish the retina—all vital for vision. \nWhile the role of Pax6 in eye development is well-studied in other species\, there has been little research on Pax6 in chickens specifically. This gap in knowledge presents an exciting opportunity to understand how the mutation of Pax6 impacts eye formation in birds. \nIn this seminar we’ll explore the role of the Pax6 transcription factor in chicken eye development and this could provide valuable insights into vertebrate eye development.

SUMMARY:Seminář Iris Durić
DESCRIPTION:“Transmembrane adaptor protein WBP1L: searching for its binding partners to understand its role in hematopoiesis” \nTransmembrane adaptor protein WBP1L\, also known as Outcome Predictor of Acute Leukemia 1 (OPAL1) was identified nearly 20 years ago as a positive prognostic marker in childhood acute lymphoblastic leukemia. More recently\, elevated WBP1L expression has also been linked to positive outcomes in ovarian cancer. Despite these clinical associations\, the physiological function of WBP1L has long remained unclear. Recently we demonstrated its involvement in the regulation of hematopoiesis\, hematopoietic stem cell functionality and hematopoietic stem cell performance during transplantation. As an adaptor protein\, WBP1L’s activity depends on its interacting partners. This presentation will describe our efforts to identify these proteins and understand their contributions to WBP1L function\, focusing on two novel interactions: one with the receptor for interferon gamma and the other with the SCFβ-TRCP1 ubiquitin ligase complex.

SUMMARY:Seminář Andrea Pauli
DESCRIPTION:“Fundamental principles during the egg-to-embryo transition” \nFertilization initiates the egg-to-embryo transition\, one of the most dramatic developmental transition resulting in the transformation of the egg from a dormant state into regulatorily and functionally distinct embryonic cells. While this transition has been studied extensively in respect to zygotic genome activation\, the molecular mechanisms that mediate sperm-egg binding and fusion during fertilization and regulate the maintenance of dormancy in the egg and re-activation in the embryo remain poorly understood. The vision of the Pauli lab is to gain mechanistic insights into the egg-to-embryo transition\, with a specific focus on the molecular control of fertilization and developmentally programmed dormancy and re-activation. \nAndrea (Andi) Pauli will talk about recent findings from her lab related to their work towards uncovering the mechanism of vertebrate fertilization and translational regulation during the egg-to-embryo transition. By combining genetic\, molecular\, cellular\, biochemical\, structural and genomics approaches in their main model organism\, the zebrafish\, the long-term vision of the Pauli lab is to unravel new concepts and molecular mechanisms governing this fascinating developmental transition that marks the beginning of life.

SUMMARY:Seminář Jakub Onhajzer\, M.Sc.
DESCRIPTION:“Reactivation of oncofetal genes reveals cellular heterogeneity and zonation in intestinal tumors” \nColorectal cancer is one of the most common malignancies. Recent studies have shown that tumor cells can reactivate so-called oncofetal genes — genes normally expressed during embryonic development but silenced in healthy adult intestinal tissue. These include Trop2 and Sca1\, both of which are reactivated during the development and progression of intestinal tumors. Using a mouse model\, we investigated the timing and molecular mechanisms driving the reactivation of these genes during the transformation of intestinal epithelial cells into tumor cells. By combining flow cytometry\, 3D microscopy\, and transcriptional profiling\, we demonstrate that the re-expression of oncofetal genes is not uniform. Instead\, it creates spatial heterogeneity — a phenomenon known as tumor zonation. This zonation is associated with the activation of fetal gene programs and the acquisition of stem cell-like properties. We also show that Sca1– and/or Trop2-positive tumor cells activate distinct molecular pathways and display unique biological properties. As several oncofetal genes (antigens) are already being explored as potential therapeutic targets\, understanding the mechanisms underlying their reactivation could contribute to the development of new targeted therapies for colorectal cancer.

SUMMARY:Seminář Jakub Sumbal
DESCRIPTION:“Probing the functional heterogeneity and hierarchy in mammary gland fibroblasts” \nIn this talk\, I will focus on the heterogeneity and hierarchy of mouse mammary fibroblasts – the predominant cell type of mammary stroma. By single cell RNA sequencing\, genetic lineage tracing and microscopy we show that fibroblast transcriptomic clusters represent spatially differentiated populations with specific functions. Moreover\, we used the lineage tracing to show differentiation traits within fibroblast populations and other stromal cell types. Finally\, I will discuss how the regulation of fibroblast differentiation may be important for proper organ morphogenesis and cancer progression.

SUMMARY:Lectures – Laboratory of Experimental Hypertension\, IPHYS
DESCRIPTION:Silvie Hojná: Anorexigenic neuropeptides in the treatment of obesity \nObesity and its complications have reached epidemic proportions. Therefore\, finding new\, more effective drugs for the treatment of obesity without side effects is a major challenge. Natural anorexigenic neuropeptides have this potential\, but their major disadvantage is their low stability in plasma and inability to cross the blood-brain barrier (BBB) after peripheral administration. One strategy to develop peptidic drugs is based on peptide lipidization. This modification leads to increased stability and half-life of the peptide in the organism and allows its application in the periphery because lipidized peptides are able to cross the BBB. In Monday’s seminar\, you will hear the full story of the development of anorexigenic analogs of prolactin-releasing peptide (PrRP)\, including their implications not only for the treatment of obesity\, but also for their other potential applications. \nMahak Arora: Role of mTOR in cardiometabolic dysfunction \nCardiometabolic disorders (CMDs) such as hypertension\, diabetes and obesity are associated with damage to key organs such as the heart\, liver and kidneys. The mammalian target of rapamycin (mTOR) signaling pathway\, which is critical for cell metabolism and growth\, is often dysregulated in these diseases. In a mouse model of steatohepatitis\, the mTOR inhibitor KU-0063794 ameliorated oxidative stress\, reduced liver triglycerides and downregulated TNF-alpha mRNA by altering mTOR signaling. Recent pilot studies in high-fat fed SHR rats treated with empagliflozin and salt-sensitive Dahl rats exposed to high or low salt diet showed significant changes in mTOR-related genes such as mtor\, akt\, pgc1a\, srebp\, etc. in liver and kidney. These results suggest that mTOR plays a key role in the regulation of cardiometabolic functions

SUMMARY:Seminář Jakub Gemperle\, Ph.D.
DESCRIPTION:“Live-cell magnetic micromanipulation of recycling endosomes reveals their direct effect on actin-based protrusions to promote invasive migration” \nEndocytic recycling pathways play key roles in the re-routing of cargoes through the cell to control a broad range of cellular processes\, and many vesicle trafficking regulators are implicated in progression of disease such as cancer. The Rab11 family (Rab11a\, Rab11b\, and Rab25) control return of internalised cargoes to the plasma membrane\, and Rab25 has been implicated in the aggressiveness of cancer by promoting invasive migration. However\, whilst Rab25 vesicles distribute to the leading of edge of moving cells\, how directly they contribute to cell protrusion is not clear. Here we adopt a magnetogenetic approach that allows direct manipulation of Rab25 positioning to show that localisation to the cell periphery drives the formation of F-actin protrusions. We demonstrate that endogenous Rab25 vesicles coordinate the positioning of key cargoes\, including the actin regulator FMNL1 and integrin β1\, with the activation of Rho GTPases at the plasma membrane to generate and maintain F-actin rich filopodial protrusions and promote cancer cell invasive migration in 3D matrix.

SUMMARY:Seminář Diego F. Joseph\, M.Sc.
DESCRIPTION:“Life Through Colors: Single-cell fluorescence-based reporter system for monitoring gene expression” \nThe presentation will depict a long journey from decision to actual making a novel reporter system for RNA silencing\, which could also be adopted for studying other mechanisms manipulating gene expression. This development lead to production of two types of triple-color reporter HeLa lines where fluorescence reporters are inserted in frame in into endogenous genes encoding highly abundant soluble nuclear proteins. The system now allows for monitoring repression (loss of specific dluorescence) and derepression (appearence of previously silenced fluorescence) across the entire population of cultured cells and\, possibly\, for high throughput screening.

SUMMARY:Seminář Jana Smolíková\, Ph.D.
DESCRIPTION:“Analysis of a novel chicken Pax6 mutant” \n Pax6 is known as the „master control gene“ for eye formation\, playing a crucial role in the development of the lens\, retina\, and other ocular structures. It drives the formation of the eye field\, initiates lens differentiation\, and helps establish the retina—all vital for vision. \nWhile the role of Pax6 in eye development is well-studied in other species\, there has been little research on Pax6 in chickens specifically. This gap in knowledge presents an exciting opportunity to understand how the mutation of Pax6 impacts eye formation in birds. \nIn this seminar we’ll explore the role of the Pax6 transcription factor in chicken eye development and this could provide valuable insights into vertebrate eye development.

SUMMARY:Seminář Goncalo Oliveira\, Ph.D.
DESCRIPTION:“Deciphering PNKP Functions in Neurological Disorders” \nHereditary mutations in polynucleotide kinase-phosphatase (PNKP)\, a key enzyme in DNA strand break repair\, result in a broad spectrum of neurological disorders\, ranging from mild neurodegeneration to severe neurodevelopmental defects. PNKP has dual phosphatase and kinase activities essential for DNA break repair\, but their specific contributions to preventing neuropathology remains unclear. In this seminar\, we will present findings from mouse genetic models that highlight the crucial role of the PNKP phosphatase domain in neurodevelopment. Additionally\, we will introduce a novel cell-based system to investigate the immediate effects of acute PNKP depletion and explore how this model helps identify key sources of DNA damage and the molecular mechanisms underlying PNKP-related disease pathology.

SUMMARY:Seminář Irena Adkins\, Ph.D.
DESCRIPTION:“Preclinical development of IL-15-based immunocytokine SOT201 and antibody-drug conjugate SOT106 for treatment of solid tumors” \nSOT201 is a novel cis-acting immunocytokine consisting of an antibody against PD-1 genetically fused to a sushi+ domain of IL-15Ra and IL-15 mutein. SOT201 targets PD-1+ TILs with a balanced cytokine potency to revive exhausted T cells in tumor microenvironment. SOT201 is currently being evaluated in Phase I clinical study VICTORIA-01 (NCT06163391) in metastatic advanced cancer patients.SOT106 is a novel antibody-drug conjugate (ADC) targeting LRRC15\, comprised of a proprietary humanized monoclonal antibody conjugated to monomethyl auristatin E (MMAE) via a beta-glucuronidase (GUSB) cleavable linker. SOT106 anti-tumor efficacy was confirmed in soft tissue sarcoma and pediatric osteosarcoma models with moderate to low LRRC15 expression supporting its clinical development as a novel therapy for sarcomas. Combined with its superior performance over a clinical benchmark ADC\, these results underscore the potential of SOT106 as a best-in-class targeted treatment for these challenging malignancies.

DESCRIPTION:Dear friends and colleagues\, \nit is my pleasure to invite you to a special seminar given by \n\n \n                      Prof. Sophie Janssens\, PhD. \nVIB-UGent Center for Inflammation Research\, Belgium \nTitle: The unfolded protein sensor IRE1 as a regulator of homeostatic dendritic cell maturation  \n  \nMonday\, April 28\, 2025 at 10 am\, in Hasek’s lecture hall\, Institute of Molecular Genetics (Videnska 1083) \nThen\, after the seminar you are invited to join us for an informal post-seminar hangout with the speaker\, 🍕 A PIZZA TALK 🍕🎤 Open Q&A on science\, careers\, life in academia\, women in science & more.👩‍🔬 For students & early-career scientists.🍕 Yes\, there will be pizza. \nProf. Sofie Janssens’s research team focuses on the role of the unfolded protein response (UPR) in several immune cell types. Their recent work has shown that the UPR is an important component in the functioning of the immune system. In CD8α conventional dendritic cells (DCs) the UPR sensor IRE-1α and its downstream transcription factor XBP-1s is constitutively active and deficiency of XBP-1s leads to defects in cross-presentation of dead cell-derived antigens. \nExamples of recent publications: \nStriking a balance: new perspectives on homeostatic dendritic cell maturation.\nBosteels Victor\, Janssens Sophie \nNATURE REVIEWS.
