SUMMARY:Seminář doc. Mgr. Lumír Krejčí\, Ph.D. - ZRUŠENO
DESCRIPTION:“Homologous Recombination – From Repair of DSBs to Processing Stalled Replication Forks and Human Diseases” \nOur lab focuses on the mechanisms ensuring accurate DNA replication and the role of homologous recombination (HR) in preventing genome instability. We investigate how endogenous hard-to-replicate regions\, G-quadruplexes (G4) and R-loops\, impact replication and contribute to disease development. A key aspect involves studying the formation and regulation of RAD51 filaments during HR. We explore how positive regulators like BRCA2 and RAD51 paralogs promote filament assembly and its stability\, while negative regulators like RECQ5 and RECQ4 helicase help balance replication stress and genome stability.

DESCRIPTION:Max Planck Institute for Medical Research\, Heidelberg \n“Viruses of unicellular eukaryotes: A tale of giants and hyperparasites” \nViruses of protists play important roles in ecology and evolution by influencing microbial population dynamics and shaping eukaryotic genomes by endogenization. Of particular interest are complex DNA viruses whose particle and genome sizes overlap with those of bacteria. In this talk\, I will highlight some remarkable properties of these giant viruses and explore their relationship with smaller DNA viruses\, called virophages\, which can parasitize giant viruses and thus act as an antiviral defense system in certain protist species.

SUMMARY:Seminář Michaela Procházková\, M.Sc.
DESCRIPTION:“CRL4COP1 ubiquitination complex as a balancer of early odontogenesis” \nCullin-RING ubiquitin ligase (CRL) complexes have been heavily studied in connection to cancer progression but there is limited evidence about their physiological roles. One of the exceptions is disruption of limb development by thalidomide induced by inhibition of CRL4 complex via regulation of Fgf8 (Ito et al.\, 2010). Notably\, Fgf8 expressing population is essential also for development of tooth primordia and we found CRL4 genes to be specifically expressed within odontognic epithelium. We further identified COP1 as a substrate binding protein which can bind ETS transcription factors\, downstream targets of Fgf pathway\, and unveiled that conditional deletion of CRL4 genes severly affects size and morphology of molar primordia and future teeth.

SUMMARY:Seminář Marie Zelená\, M.Sc.
DESCRIPTION:“Every stick has two ends – Using high resolution imaging to characterize both ends of the eukaryotic flagellum” \nThe eukaryotic flagellum is important for cell motility. The microtubule-based axoneme generating the flagellar beating has been extensively studied. However\, additional structures are associated with the proximal and distal end of the flagellum\, with their composition and processes of their formation being poorly understood. \nTo gain an insigth into these structures we have studied them in the protozoan parasite Trypanosoma brucei\, which is experimentally highly tractable. First\, we focused on the flagellar pocket around the proximal end of the flagellum\, which is the exclusive site for endocytosis and exocytosis of the parasite. Using expansion microscopy we were able to define discrete stages of the flagellar pocket division and formation of the flagellar pocket collar\, which seals the pocket. Second\, we took advantage of our knowledge of the flagellum distal-end proteome and combined it with expansion microscopy and cryo-electron tomography to characterize the enigmatic microtubule plugs at the distal end of the flagellum. \nOur work elucidates aspects of the flagellar biology of an important parasite. Moreover\, given the conserved nature of the organelle\, our results have also implications for flagella across eukaryotes.

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.

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

SUMMARY:Seminář Jana Smolíková\, Ph.D. - ZRUŠENO
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.
