SUMMARY:Institut Jacques Monod lecture - Sophie G. Martin
DESCRIPTION:On Friday\, February 7th 2025\, Sophie G. Martin (Department of Molecular and Cellular Biology\, University of Geneva\, Switzerland) will present an Institut Jacques Monod lecture on the theme: \nSignaling and actin focus architecture for cell-cell fusion \n  \nAbstract: \nSexual reproduction is ubiquitous amongst eukaryotes. This requires alternation of cell-cell (gamete) fusion and genome reduction through meiosis. My lab has been using the yeast sexual reproduction pathway to study how cells polarize to find a mate and mount a fusion reaction. In the fission yeast Schizosaccharomyces pombe\, sexual reproduction occurs between P and M cells\, which communicate through pheromone-GPCR-MAPK signaling\, driving the formation of cell pairs. Transition from gametes to zygote involves local cell wall digestion at the point of gamete contact\, while preserving cell integrity. We have shown that cell-cell fusion requires the actin fusion focus\, an aster-like assembly of linear actin filaments assembled by the formin Fus1\, which concentrates both signaling molecules and secretory vesicles carrying cell wall digestion enyzmes. I will present our recent work on the molecular mechanisms of formation of the actin fusion focus\, which require both formation of a formin biomolecular condensate and cytoskeletal focusing through formin-myosin feedback. I will also describe our progress in understanding the roles of local MAPK and PAK signaling for cells to pierce their cell wall once and only once.

SUMMARY:Institut Jacques Monod  lectures- Richard Benton
DESCRIPTION:On Tuesday\, February 11th\, Richard Benton (Center for Integrative Genomics\, University of Lausanne) will present an Institut Jacques Monod lectures on the theme: \nFatal chemosensation\, and how insects fight back \n  \nAbstract: \nInsecticide resistance is a widespread challenge for the management of vectors transmitting pathogens and agricultural pests\, requiring a better understanding of the genetic mechanisms underlying the evolution of resistance. Drosophila sechellia is a compelling model for such studies as it naturally evolved resistance to octanoic acid\, an abundant chemical of its noni fruit host that is toxic for other insects\, including close relatives D. simulans and D. melanogaster. We have used a multi-pronged strategy to identify genes contributing to octanoic acid resistance. We began by experimentally-evolving D. simulans strains with higher tolerance to octanoic acid and determined the resulting genetic architecture. To identify specific candidate genes\, we integrated this analysis with a genome-wide association study of octanoic acid resistance in D. simulans and a genome-wide CRISPR selection screen upon octanoic acid exposure in D. melanogaster S2R+ cultured cells. We identified four candidates\, with diverse predicted molecular and expression properties\, and validated their relevance using genetic analyses in D. melanogaster. Two of these genes displayed an increased expression in the experimentally-evolved strains\, paralleling their higher levels of expression in D. sechellia. Our results suggest an adaptive role of these genes in shaping toxin resistance both under laboratory conditions and during D. sechellia’s evolutionary history.

SUMMARY:Seminar - Felix Ruhnow
DESCRIPTION:Invited by the Centre for Genomic Regulation\, Felix Ruhnow will present a seminar on the theme: \nNuMA is a mitotic adaptor protein that activates dynein and connects it to microtubule minus ends \n  \nAbstract: \nNuclear mitotic apparatus protein (NuMA) is indispensable for the mitotic functions of the major microtubule minus-end directed motor cytoplasmic dynein 1. NuMA and dynein are both essential for correct spindle pole organization. How these proteins cooperate to gather microtubule minus ends at spindle poles remains unclear. Here we use microscopy-based in vitro reconstitutions to demonstrate that NuMA is a dynein adaptor\, activating processive dynein motility together with dynein’s cofactors dynactin and Lissencephaly-1 (Lis1). Additionally\, we find that NuMA binds and stabilizes microtubule minus ends\, allowing dynein/dynactin/NuMA. to transport microtubule minus ends as cargo to other minus ends. We further show that the microtubule-nucleating γ-tubulin ring complex (γTuRC) hinders NuMA binding and that NuMA can only cap minus ends of γTuRC-nucleated microtubules after γTuRC release. These results provide new mechanistic insight into how dynein\, dynactin\, NuMA\, Lis1 together with γTuRC and uncapping proteins cooperate to organize spindle poles in cells.

SUMMARY:Institut Jacques Monod Seminar - Peter Andolfatto
DESCRIPTION:Invited by the Courtier\, Peter Andolfatto (Professor\, Dept. of Biological Sciences\, Columbia University) will present an Institut Jacques Monod seminar on the theme: \nThe evolution of toxin-resistant Na+\,K+-ATPases: new insights from frogs and fireflies  \n  \nWe study the process of adaptive evolution through the lens of repeated adaptation of many distantly species to a similar selection pressure (i.e. “parallel evolution”). Over the past decade\, we have explored patterns of adaptation in the context of animals that have specialized in eating plants\, or other animals\, that contain toxic cardiotonic steroids (CTS). CTS are toxic to animals because they inhibit sodium-potassium ATPase\, a key enzyme in animals needed in everything from maintaining cell homeostasis\, muscle contraction to neuron activity. Here I review our most recent work combining comparative molecular evolution\, molecular and biochemical assays and in vivo engineering of Drosophila to deduce the rules governing the adaptive evolution of CTS resistance in animals. Together\, our results have interesting implications for how epistasis and pleiotropy both limit the rate of adaptive protein evolution and increase its predictability.

SUMMARY:[Cancelled] Institut Jacques Monod Seminars - Marla Sokolowski
DESCRIPTION:This seminar is cancelled.\n  \nInvited by the par l’équipe Courtier\, Marla Sokolowski (Department of Ecology and Evolutionary Biology\, University of Toronto) will present an Institut Jacques Monod Seminar on the theme: \nThe foraging gene: will that be for here or to go? \nAbstract: \nThe Drosophila melanogaster foraging (for) gene\, with its rover and sitter larval foraging variants\, is an established behaviour genetics model. Orthologues of the foraging gene also modulate the individual and social behaviour of a wide range of species including the regulation of behaviour in eusocial insects. In Drosophila\, foraging modifies the expression of multiple traits\, including feeding and foraging\, stress tolerance\, sleep\, metabolism\, dispersal\, escape responses\, social behaviour\, and learning and memory. From a social context perspective\, Drosophila foraging affects larval clustering during foraging under high larval densities\, adult social behaviour and social networks\, and social learning. We wondered how foraging accomplishes its behavioural pleiotropy at the molecular level. We found that D. melanogaster foraging has a complex modular genomic structure with four promoters\, 21 transcripts\, and eight protein isoforms. The four promoter modules are differentially regulated during development and in a timescale\, tissue\, and cell-type dependent manner. Two examples illustrate these findings: the epigenetic regulation of the adult rover-sitter foraging-related phenotypes by G9a\, a histone methyltransferase\, and the regulation of differences in the latency of rover compared to sitter larval escape responses to noxious stimuli such as parasitoid wasps. Our work provides a nuanced picture of the molecular basis of foraging’s pleiotropy.

SUMMARY:Paris Postdoc Seminar - Nathaniel Henneman
DESCRIPTION:Invited by the Institut Jacques Monod\, Nathaniel Henneman (team of Ganna Panasyuk at Institut Necker Enfants Malades (INEM)) will present a Paris Postdoc Seminar on the theme: \nNuclear functions of nutrient sensing signaling for metabolic adaptation \n  \nIntroduction & abstract: \nI am a Postdoc in the team of Ganna Panasyuk at Institut Necker Enfants Malades (INEM). I graduated from Bates College (USA) in 2016\, majoring in Biology. I then spent two years working on retinal degeneration at Emory University before obtaining my master’s degree at University of Paris Descartes in 2019 and defended my PhD in December 2023. \nOne of the key questions I am to address in my work is how cellular metabolism\, gene expression and transcription\, are all coordinated. Energy stress in fasting is managed by activating autophagy and promoting the transcriptional remodeling of metabolism. Cytosolic nutrient sensors coordinate extracellular nutrient availability with intracellular metabolic processes to allow for cell survival. Class 3 PI3K is a highly conserved nutrient sensor known to regulate autophagy and endocytosis in response to varying nutrient conditions. It’s direct role in transcription\, however\, was only suggested in few studies in yeast and plants. However\, we believe there is a nuclear pool of class 3 PI3K that directly regulates gene expression for metabolic adaptation. My work aims to address this unmet burden in the field. We find that nuclear class 3 PI3K regulates the transcriptional response to nutrient stress by controlling RNA Polymerase II\, the Set1/COMPASS methyltransferase\, and nuclear methionine to SAM flux. I aim to understand how these players are needed for our fasting adaptation and how these mechanisms could affect our metabolic resilience.

SUMMARY:Institut Jacques Monod Lecture - Andrea Musacchio
DESCRIPTION:On Friday\, March 7th\, Andrea Musacchio (Max Planck Institute of Molecular physiology) will present a Institut Jacques Monod Lecture on the theme: \nFeedback control of mitosis in the context of the kinetochore \n  \nAbstract: \nKinetochores provide chromosomes with points of attachment to spindle microtubules during cell division\, and are therefore essential for genome inheritance and the propagation of life. In addition to binding microtubules\, kinetochores control mitotic surveillance mechanisms that promote chromosome bi-orientation (the error correction mechanism) and prevent premature mitotic exit in presence of incomplete or incorrect microtubule attachments (spindle assembly checkpoint\, SAC). Elimination of the NDC80 complex\, the main microtubule receptor of kinetochores\, causes a SAC deficiency\, identifying this complex as a crucial regulatory focus for checkpoint function. In recent years\, there has been considerable progress in understanding how the SAC effector\, known as the mitotic checkpoint complex (MCC)\, assembles from its individual components to inhibit its target\, the anaphase promoting complex/cyclosome (APC/C). Conversely\, how microtubule attachment to kinetochores regulates the SAC remains incompletely understood. From a molecular perspective\, answering this question implies investigating the mechanisms that promote targeting of the SAC proteins to unattached kinetochores\, and suppress it upon microtubule binding and biorientation. In our recent work\, we have combined biochemical reconstitutions\, structural biology/modelling\, and cell biology to gain insights into this fundamental biological question.

SUMMARY:Institut Jacques Monod seminar - Mateusz C. Ambrozkiewicz
DESCRIPTION:Invited by the Konstantinides Lab\, Dr. Mateusz C. Ambrozkiewicz\, FENS-Kavli Scholar (Institute for Cell Biology and Neurobiology\, Charité University Hospital\, Berlin\, Germany) will present an Institut Jacques Monod seminar on the theme: \nProteostatic Mechanisms of Cellular Diversification in the Developing Brain \nAbstract: \nFormation of functional circuits in the adult brain is a biological fundament for its executive role in the living organism and requires specification of neurons\, their correct positioning\, formation of dendrites and synapses. In this talk\, I will present our current research on the translational mechanisms and post-translational modifications orchestrating neuronal diversification in the developing brain. Particularly\, I will shed light on the specific post-transcriptional requirements for neuronal progenitors\, including the dynamics of protein synthesis as well as the role of ubiquitination-dependent degradation in healthy and diseased brain. I will show how deciphering a molecular mechanism at the basis of neurodevelopmental disease etiology can be used to propose therapeutic strategy impinging on modulating the activity of cellular proteostasis effectors\, such as the E3 ubiquitin ligases.

SUMMARY:Institut Jacques Monod Seminar - Lionel Christiaen
DESCRIPTION:Invited by the Minc Lab\, Lionel Christiaen (Michael Sars Centre\, University of Bergen\, Bergen\, Norway) will present an Institut Jacques Monod Seminar on the theme: \nRegulation of deterministic development \nAbstract: \nChristiaen’s research aims at understanding how tissue-specific regulatory programs and cell-cell communication coordinate cellular behavior in the context of animal development\, regeneration and evolution. His laboratory focuses on mesodermal lineages that produce both heart and head muscles\, using the ascidian Ciona as model. His laboratory has contributed seminal findings in developmental and evolutionary biology\, identifying key processes contributing to human congenital disorders. The Ciona model provides a unique opportunity to study the regulation of chordate development at single cell resolution\, thanks to a highly deterministic (“hard-wired”) mode of embryogenesis. However\, recent attempts to uncover the impact of varying temperatures in a changing world are beginning to reveal regulative mechanisms of thermal adaptation.

SUMMARY:Seminar - Suzette Lust
DESCRIPTION:Invited by the Institut Jacques Monod\, Suzette Lust (Postdoctoral researcher in Danijela Matic Vignjevic’s team – Cell migration and invasion Laboratory at Institut Curie) will present a seminar on the theme: \nUnderstanding the role of interstitial flow in vascular smooth muscle cell phenotype in the context of aortic aneurysms \n  \nThis seminar is part of the Paris Postdocs Seminars series. \nAbstract: \nAortic aneurysms are abnormal enlargements of blood vessel diameter caused by aberrant extra-cellular matrix (ECM) remodelling. As the tissue dilates\, it loses its mechanical integrity\, exposing patients to risk of highly fatal aortic dissections or ruptures. This is mediated in part by phenotypic switching and or apoptosis of the intima-resident vascular smooth muscles (VSMCs). What drives this pathology is not well understood\, particularly in the case of aneurysms in Bicuspid Aortic Valve disease (BAV) patients\, a congenital condition characterised by the malformation of the aortic valve resulting in only 2 leaflets. Improvements in imaging techniques have now allowed pathological blood flow patterns to be correlated to aneurysm morphology and indeed there is increasing evidence that mechanotransduction from flow may be a driver of aneurysm development. Blood flow imparts mechanical forces to cells through stretching and frictional shear forces and we are focused here on the interstitial flow driven into the wall by differential pressure gradients within the aorta. \nWe hypothesise that interstitial flow plays a crucial role in regulating VSMC phenotype and ECM interactions and that this may be used to correlate disrupted flow patterns seen in BAV patients to the morphology changes in their aortas. \nTo test this hypothesis\, we created a reductionist in-vitro model culturing VSMCs in 3D under interstitial flow. We combined a synthetic PEG based ECM mimicking hydrogel with primary cultures of VSCMs with a microfluidics setup. \nWe showed hydrogels doctored with degradable bioactive peptides could be broken down by exogenous and cell derived MMPs. We measured hydrogel permeability using 2 separate techniques which confirmed the material to have a low permeability compared to other standard hydrogels\, on the order of 10−16 m2. Furthermore\, we characterised mass transport of solutes within hydrogels and were able to demonstrate a negligible impact of changing polymer solid content on diffusivity in hydrogels of up to 5% weight/volume for molecules up to 40 kDa in size. Via production of MMPs\, VSMCs break down the hydrogel and importantly by day 7 of culture\, we detected newly synthesised fibronectin\, collagen 1 and 4 proteins. We stimulated encapsulated cells with interstitial flows demonstrating that cells align to the flow direction. Finally\, we performed RNA sequencing on 3 human patient samples comparing standard culture conditions\, non-flow stimulated encapsulated cells and interstitial-flow stimulated cells. The data set reveals significant upregulation of genes in multiple pathways associated with cyclic AMP production\, which plays a crucial role in regulating VSMC contractility and calcium signalling and hence phenotype. The data suggests that this is mediated via activation of G-protein receptors leading to increased expression of adenylyl cyclase but this remains to be confirmed. \nIn conclusion\, we developed a novel in-vitro platform to study the impact of interstitial flow on VSMC behaviour. Our data suggests that interstitial flow may play a regulating role in determining VSMC phenotype with potential consequences for matrix remodelling in disease.

SUMMARY:Institut Jacques Monod Seminar - Marion Silies
DESCRIPTION:Invited by the Konstantinides Lab\, Dr. Marion Silies (Johannes-Gutenberg-University Mainz\, Germany) will present an Institut Jacques Monod seminar on the theme: \nHeterogeneity of connectivity and function in the fly visual system \nAbstract: \nVisual systems are considered homogeneous structures where repeating visual units contain the same circuit motifs that fulfil the same functional role\, leading to translation invariance. However\, our recent work\, analyzing full fly brain connectomes\, revealed remarkable heterogeneity\, even within anatomically and genetically identifiable cell types. I will describe this heterogeneity in synaptic connectivity\, and address where it arises developmentally. Furthermore\, I will discuss how heterogeneous circuit motifs can lead to degeneracy of neuronal function\, and thus to both\, reliablility and flexiblity of neuronal information processing in the visual system.

SUMMARY:Seminar - Daehan Lee
DESCRIPTION:Invited by the Courtier lab and the Konstantinides Lab\, Daehan Lee (Department of Biological Sciences\, College of Natural Sciences\, Sungkyunkwan University\nSuwon 16419\, Republic of Korea) will present a seminar on the theme: \nEcological Transitions Across Scales: Rewiring Sense\, Losing Sex\, Dodging Death\, and Becoming Complex \nAbstract: \nEcological transitions—changes in the physical\, chemical\, or biotic environment experienced by organisms—can have profound effects on developmental\, physiological\, and evolutionary trajectories. In this seminar\, I will examine how ecological shifts across multiple scales drive remodeling of biological systems\, from gene regulatory networks to life history strategies. Using a set of diverse model organisms\, I will present evidence for ecological transitions as catalysts of evolutionary change: sensory system reorganization during host specialization in Drosophila sechellia; the evolutionary loss of sexual reproduction under laboratory conditions in Caenorhabditis elegans; stage-specific aging and regeneration linked to ecological niches in the life cycle of jellyfish; and the emergence of multicellularity in choanoflagellates in response to environmental and social cues. Together\, these studies illustrate how ecological context shapes the evolution of complexity\, modulates developmental plasticity\, and alters fundamental features of animal biology.

SUMMARY:Institut Jacques Monod Seminar - Frédéric Pincet
DESCRIPTION:Invited by the Romet-Lemonne/Jégou\, Frédéric Pincet (CNRS/ENS-PLS\, Paris) will present an Institut Jacques Monod seminar on the theme: \nThe Dual Role of Golgins in Maintaining Golgi Structure and Mediating Vesicle Traffic \n  \nAbstract: \nThe architecture of the Golgi apparatus is remarkably complex. In mammalian cells\, it is composed of stacks of disk-shaped membrane compartments that are laterally connected to form a ribbon-like structure. These stacks are polarized along the cis-to-trans axis and are embedded within a dense protein matrix\, whose primary components belong to the Golgin protein family. This refined organization is transiently lost during mitosis\, when the Golgi apparatus disperses into small vesicular and tubular remnants. However\, during telophase\, these remnants rapidly reassemble within minutes\, restoring the original architecture and cisternal composition. Even during interphase\, the integrity of the Golgi architecture is continuously challenged by dynamic processes\, including intensive vesicular trafficking both within the Golgi and with neighboring compartments\, as well as by cisternal maturation. As a result\, the Golgi apparatus presents a seemingly paradoxical combination of dynamic plasticity and structural robustness. In this seminar\, I will propose that Golgins act as key regulators balancing this duality. Golgins can function both as vesicle tethers\, facilitating trafficking\, and as structural scaffolds\, promoting the spontaneous organization of the Golgi matrix. We tested this hypothesis using a combination of in vitro biophysical and biochemical assays\, as well as super-resolution imaging of Golgin localization. Our results show that Golgins can self-assemble into two-dimensional condensates exhibiting a hierarchical set of interactions correlated with Golgi organization. Simultaneously\, Golgins and their condensates are capable of specifically tethering vesicles\, thus maintaining efficient vesicular trafficking within the matrix.

SUMMARY:Seminar - Irene Basili
DESCRIPTION:Invited by the Institut Jacques Monod\, Irene Basili will present a seminar on the theme: \nAMBRA1 controls the Sonic Hedgehog signaling pathway and SHH-medulloblastoma \nAbstract: \nAMBRA1 (Autophagy and Beclin 1 Regulator 1) is primarily recognized as a tumor suppressor\, however its role as a tumor promoter has garnered increasing attention. Here\, leveraging clinical data of an international multi-omic medulloblastoma (MB) cohort\, we identified that elevated AMBRA1 protein levels\, independently of its mRNA expression\, correlate with poor prognosis in the Sonic Hedgehog subgroup (MBSHH) compared to other MB variants. Mechanistically\, AMBRA1 enhances SHH signaling by stabilizing GLI1\, the pathway’s final effector\, via inhibition of its βTrCP-mediated degradation. Additionally\, AMBRA1 protein stability is modulated by the REN E3 ubiquitin ligase\, a tumor suppressor gene lost in MBSHH. Inhibition of AMBRA1 blocks MBSHH growth in murine and patient-derived pre-clinical models\, highlighting its therapeutic potential. Moreover\, combining AMBRA1 knockdown with FDA-approved SHH inhibitors enhances antitumor efficacy. These findings identify the AMBRA1/βTrCP/REN axis as a key regulatory mechanism in SHH signaling and discover an unrecognized function of AMBRA1 in MBSHH\, providing actionable insights for innovative targeted therapies. \nThis seminar is part of the Paris Postdoc seminar series.

SUMMARY:Institut Jacques Monod Seminar - Frank Maixner et Sabry Sarhan
DESCRIPTION:Invited by the Grange/Geigl\, Frank Maixner and Sabry Sarhan (Eurac Research – Institute for Mummy Studies\, Bolzano\, Italy) will present an Institut Jacques Monod seminar on theme: \nGenome wide data of a Penicillium roqueforti strain from Iron Age Austria: the oldest molecular evidence for fermented blue cheese. \nAbstract: \nThe application of metagenomic analysis on dated ancient human specimens opens a window into the past that enables scientists to address unique evolutionary research questions. Paleofeces are an important source of information to study the evolution of dietary habits and human health. The UNESCO World Heritage region of Hallstatt-Dachstein/Salzkammergut is one of Europe’s oldest cultural and industrial landscapes; its underground salt mines dating back at least to the 14th century BC are one of the few archaeological sites where paleofeces are well preserved. Here we subjected human paleofeces dated from the Bronze Age to early Modern Times to an in-depth microscopic\, metagenomic and proteomic analysis. This allowed us to reconstruct the diet of the former population and gain insights into their ancient gut microbiome composition. Dietary survey identified a highly fibrous\, carbohydrate-rich diet supplemented with proteins from broad beans and occasionally with fruits\, nuts\, or animal food. Linked to these traditional dietary habits all ancient miners up to the early Modern times have gut microbiome structures akin to modern non-Westernized individuals which may indicate a shift in the gut community composition of modern Westernized populations due to quite recent dietary and lifestyle changes. When we extended our microbial survey to fungi present in the paleofeces\, we observed in one of the Iron Age samples a high abundance of Penicillium roqueforti DNA. Genome-wide analysis placed the ancient P. roqueforti strain into the current non-Roquefort blue cheese diversity next to modern variants from different parts of the Alps (e.g. Termignon). Our findings present the earliest molecular evidence for blue cheese consumption during Iron Age Europe\, which opens a new opportunity to better understand the domestication history of blue cheese fermentation.

SUMMARY:Institut Jacques Monod Seminar - Carlos Estella
DESCRIPTION:Invited by the Konstantinides Lab\, Carlos Estella (Laboratory of stress response and morphogenesis. Centro de Biología Molecular CSIC-UAM\, Madrid\, Spain) will present an Institut Jacques Monod seminar on the theme: \nA cross talk between p53 and the cell cycle regulates apoptotic induction and tumor formation in Drosophila \nAbstract: \nCell division is essential for tissue regeneration and organismal survival. However\, errors in this process can lead to uncontrolled cell proliferation and cancer. The tumor suppressor gene p53 plays a critical role in maintaining genomic integrity by coordinating cellular responses to stress\, such as DNA damage. These responses include cell cycle arrest\, DNA repair\, senescence\, or apoptosis. Importantly\, how these responses are precisely coordinated to maintain tissue homeostasis remains poorly understood. \nTo address this challenge\, simple genetic models are needed to study the precise regulation of cellular responses triggered by p53 and its role in tumorigenesis. To simplify the study of p53’s functions\, we use Drosophila melanogaster\, which has a single p53 homolog. Drosophila serves as a powerful genetic model due to its highly conserved pathways and sophisticated genetic tools. Notably\, approximately 85% of human cancer-related genes have orthologs in flies. In this seminar I´ll discuss recent work from our laboratory that demonstrated how the cellular context and proliferative status of a cell significantly impact p53’s ability to regulate the various responses triggered by DNA damage. In addition\, I´ll present the tumorigenic potential of p53 when its apoptotic role is inhibited. We find that cells with chronic p53 activity that have inhibited its apoptotic potential acquire a persistent activity of the JNK pathway\, which drives them into a senescent-like status and induce the non-autonomous overgrowth of the surrounding tissue. These results lead us to propose a model in which cell cycle progression and p53 pro-apoptotic activity are molecularly connected to coordinate the appropriate response after DNA damage.
