Very recently, optogenetic methods have been paired with optical reporters in novel drug screening platforms. In these all-optical platforms, light remotely activated ion channels and kinases thereby obviating the use of electrophysiology or reagents. Consequences were remarkable operational simplicity, throughput, and cost-effectiveness that culminated in the identification of new drug candidates. These blueprints for all-optical assays also revealed potential pitfalls and inspire all-optical variants of other screens, such as those that aim at better understanding dynamic drug action or orphan protein function."}],"type":"journal_article","_id":"1026","quality_controlled":"1","project":[{"_id":"255BFFFA-B435-11E9-9278-68D0E5697425","name":"In situ real-time imaging of neurotransmitter signaling using designer optical sensors (HFSP Young Investigator)","grant_number":"RGY0084/2012"},{"_id":"25548C20-B435-11E9-9278-68D0E5697425","name":"Microbial Ion Channels for Synthetic Neurobiology","call_identifier":"FP7","grant_number":"303564"},{"_id":"255A6082-B435-11E9-9278-68D0E5697425","name":"Molecular Drug Targets","call_identifier":"FWF","grant_number":"W1232-B24"}],"publication_status":"published","publisher":"Elsevier","author":[{"first_name":"Viviana","last_name":"Agus","full_name":"Agus, Viviana"},{"full_name":"Janovjak, Harald L","first_name":"Harald L","id":"33BA6C30-F248-11E8-B48F-1D18A9856A87","last_name":"Janovjak","orcid":"0000-0002-8023-9315"}],"title":"Optogenetic methods in drug screening: Technologies and applications","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","article_processing_charge":"No","publist_id":"6365","department":[{"_id":"HaJa"}],"language":[{"iso":"eng"}],"article_type":"original","volume":48,"date_created":"2018-12-11T11:49:45Z","day":"01","status":"public","publication":"Current Opinion in Biotechnology","doi":"10.1016/j.copbio.2017.02.006","ec_funded":1,"oa_version":"None","isi":1,"date_published":"2017-12-01T00:00:00Z","month":"12","intvolume":"        48","acknowledgement":"This work was supported by grants of the European Union Seventh Framework Programme (CIG-303564), the Human Frontier Science Program (RGY0084_2012), and the Austrian Science Fund FWF (W1232 MolecularDrugTargets).","date_updated":"2023-09-22T09:26:06Z","external_id":{"isi":["000418313200003"]},"page":"8 - 14","year":"2017"},{"year":"2017","external_id":{"isi":["000408077400015"]},"page":"90 - 97","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","date_updated":"2024-03-25T23:30:15Z","oa":1,"month":"08","intvolume":"        46","date_published":"2017-08-01T00:00:00Z","related_material":{"record":[{"id":"6263","relation":"dissertation_contains","status":"public"}]},"isi":1,"ec_funded":1,"oa_version":"Published Version","doi":"10.1016/j.copbio.2017.02.013","publication":"Current Opinion in Biotechnology","date_created":"2018-12-11T11:49:45Z","tmp":{"short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"ddc":["570"],"day":"01","status":"public","volume":46,"language":[{"iso":"eng"}],"pubrep_id":"801","article_type":"original","article_processing_charge":"Yes (in subscription journal)","publist_id":"6364","department":[{"_id":"ToBo"}],"file":[{"relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_id":"5846","creator":"dernst","file_size":858338,"date_updated":"2019-01-18T09:57:57Z","date_created":"2019-01-18T09:57:57Z","success":1,"file_name":"2017_CurrentOpinion_Lukaciinova.pdf"}],"author":[{"full_name":"Lukacisinova, Marta","first_name":"Marta","id":"4342E402-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2519-8004","last_name":"Lukacisinova"},{"full_name":"Bollenbach, Mark Tobias","id":"3E6DB97A-F248-11E8-B48F-1D18A9856A87","first_name":"Mark Tobias","last_name":"Bollenbach","orcid":"0000-0003-4398-476X"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","title":"Toward a quantitative understanding of antibiotic resistance evolution","has_accepted_license":"1","publisher":"Elsevier","project":[{"_id":"25E9AF9E-B435-11E9-9278-68D0E5697425","name":"Revealing the mechanisms underlying drug interactions","grant_number":"P27201-B22","call_identifier":"FWF"},{"call_identifier":"FP7","grant_number":"303507","name":"Optimality principles in responses to antibiotics","_id":"25E83C2C-B435-11E9-9278-68D0E5697425"},{"name":"Revealing the fundamental limits of cell growth","_id":"25EB3A80-B435-11E9-9278-68D0E5697425","grant_number":"RGP0042/2013"}],"publication_status":"published","_id":"1027","quality_controlled":"1","citation":{"short":"M.

To address this problem, recent work ranging from clinical studies to theoretical modeling has provided valuable insights into the mechanisms of resistance, its emergence and spread, and ways to counteract it. A deeper understanding of the underlying dynamics of resistance evolution will require a combination of experimental and theoretical expertise from different disciplines and new technology for studying evolution in the laboratory. Here, we review recent advances in the quantitative understanding of the mechanisms and evolution of antibiotic resistance. We focus on key theoretical concepts and new technology that enables well-controlled experiments.

Optogenetic methods that are sensitive to green light and can be used to break protein complexes are not broadly available but would enable multichromatic experiments with previously inaccessible biological targets. Herein, we repurposed cobalamin (vitamin B12) binding domains of bacterial CarH transcription factors for green-light-induced receptor dissociation. In cultured cells, we observed oligomerization-induced cell signaling for the fibroblast growth factor receptor 1 fused to cobalamin-binding domains in the dark that was rapidly eliminated upon illumination. In zebrafish embryos expressing fusion receptors, green light endowed control over aberrant fibroblast growth factor signaling during development. Green-light-induced domain dissociation and light-inactivated receptors will critically expand the optogenetic toolbox for control of biological processes."}],"file_date_updated":"2019-01-18T09:39:55Z","type":"journal_article","publication_identifier":{"issn":["14337851"]},"citation":{"mla":"Kainrath, Stephanie, et al. “Green-Light-Induced Inactivation of Receptor Signaling Using Cobalamin-Binding Domains.” <i>Angewandte Chemie - International Edition</i>, vol. 56, no. 16, Wiley-Blackwell, 2017, pp. 4608–11, doi:<a href=\"https://doi.org/10.1002/anie.201611998\">10.1002/anie.201611998</a>.","apa":"Kainrath, S., Stadler, M., Gschaider-Reichhart, E., Distel, M., &#38; Janovjak, H.

The input is a graph where the edges are labeled with different types of opening and closing parentheses, and the reachability information is computed via paths whose parentheses are properly matched. We present new results for Dyck reachability problems with applications to alias analysis and data-dependence analysis. Our main contributions, that include improved upper bounds as well as lower bounds that establish optimality guarantees, are as follows: First, we consider Dyck reachability on bidirected graphs, which is the standard way of performing field-sensitive points-to analysis. Given a bidirected graph with n nodes and m edges, we present: (i) an algorithm with worst-case running time O(m + n · α(n)), where α(n) is the inverse Ackermann function, improving the previously known O(n2) time bound; (ii) a matching lower bound that shows that our algorithm is optimal wrt to worst-case complexity; and (iii) an optimal average-case upper bound of O(m) time, improving the previously known O(m · logn) bound. Second, we consider the problem of context-sensitive data-dependence analysis, where the task is to obtain analysis summaries of library code in the presence of callbacks. Our algorithm preprocesses libraries in almost linear time, after which the contribution of the library in the complexity of the client analysis is only linear, and only wrt the number of call sites. Third, we prove that combinatorial algorithms for Dyck reachability on general graphs with truly sub-cubic bounds cannot be obtained without obtaining sub-cubic combinatorial algorithms for Boolean Matrix Multiplication, which is a long-standing open problem. Thus we establish that the existing combinatorial algorithms for Dyck reachability are (conditionally) optimal for general graphs. We also show that the same hardness holds for graphs of constant treewidth. Finally, we provide a prototype implementation of our algorithms for both alias analysis and data-dependence analysis. Our experimental evaluation demonstrates that the new algorithms significantly outperform all existing methods on the two problems, over real-world benchmarks.","lang":"eng"}],"arxiv":1,"citation":{"chicago":"Chatterjee, Krishnendu, Bhavya Choudhary, and Andreas Pavlogiannis. “Optimal Dyck Reachability for Data-Dependence and Alias Analysis.” <i>Proceedings of the ACM on Programming Languages</i>.

Two traces are observationally equivalent if every read event observes the same write event in both traces. While the traditional Mazurkiewicz equivalence is control-centric, our new definition is data-centric. We show that our observation equivalence is coarser than the Mazurkiewicz equivalence, and in many cases even exponentially coarser.

Like others, we use variant functions (a.k.a. \"super-martingales\") that are real-valued and decrease randomly on each loop iteration; but our key innovation is that the amount as well as the probability of the decrease are parametric.

How does biparental sexual reproduction influence the chances of population persistence compared to clonal reproduction or selfing? In this article, we set up a one‐locus two‐allele model for adaptation in diploid species, where rescue is contingent on the establishment of the mutant homozygote. Reproduction can occur by random mating, selfing, or clonally. Random mating generates and destroys the rescue mutant; selfing is efficient at generating it but at the same time depletes the heterozygote, which can lead to a low mutant frequency in the standing genetic variation. Due to these (and other) antagonistic effects, we find a nontrivial dependence of population survival on the rate of sex/selfing, which is strongly influenced by the dominance coefficient of the mutation before and after the environmental change. Importantly, since mating with the wild‐type breaks the mutant homozygote up, a slow decay of the wild‐type population size can impede rescue in randomly mating populations."}],"type":"journal_article","project":[{"_id":"25B07788-B435-11E9-9278-68D0E5697425","name":"Limits to selection in biology and in evolutionary computation","grant_number":"250152","call_identifier":"FP7"}],"publication_status":"published"},{"external_id":{"isi":["000399506600005"]},"page":"25 - 29","year":"2017","intvolume":"       122","month":"06","date_published":"2017-06-01T00:00:00Z","oa":1,"date_updated":"2023-09-20T12:08:18Z","doi":"10.1016/j.ipl.2017.02.003","publication":"Information Processing Letters","isi":1,"oa_version":"Submitted Version","ec_funded":1,"volume":122,"status":"public","day":"01","date_created":"2018-12-11T11:49:57Z","ddc":["000"],"publist_id":"6323","department":[{"_id":"KrCh"},{"_id":"HeEd"}],"article_processing_charge":"No","pubrep_id":"991","language":[{"iso":"eng"}],"publisher":"Elsevier","has_accepted_license":"1","file":[{"file_name":"IST-2018-991-v1+2_2018_Chatterjee_Pushdown_PREPRINT.pdf","date_updated":"2019-10-15T07:44:51Z","date_created":"2018-12-12T10:13:17Z","content_type":"application/pdf","file_id":"4998","file_size":247657,"creator":"system","access_level":"open_access","relation":"main_file"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","author":[{"full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","last_name":"Chatterjee","orcid":"0000-0002-4561-241X"},{"id":"464B40D6-F248-11E8-B48F-1D18A9856A87","first_name":"Georg F","orcid":"0000-0002-8882-5116","last_name":"Osang","full_name":"Osang, Georg F"}],"title":"Pushdown reachability with constant treewidth","publication_status":"published","project":[{"call_identifier":"FWF","grant_number":"P 23499-N23","name":"Modern Graph Algorithmic Techniques in Formal Verification","_id":"2584A770-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FWF","grant_number":"S11407","_id":"25863FF4-B435-11E9-9278-68D0E5697425","name":"Game Theory"},{"_id":"2581B60A-B435-11E9-9278-68D0E5697425","name":"Quantitative Graph Games: Theory and Applications","grant_number":"279307","call_identifier":"FP7"}],"type":"journal_article","file_date_updated":"2019-10-15T07:44:51Z","scopus_import":"1","abstract":[{"text":"We consider the problem of reachability in pushdown graphs.

In that case, the dynamics of the frequency of one of the genotypes is approximately described by a generalized Fisher–Kolmogorov–Petrovskii–Piskunov (F–KPP) equation. This generalized F–KPP equation with (nonlinear) frequency-dependent diffusion and advection terms admits traveling wave solutions that characterize the invasion of the dominant genotype. Our existence results generalize the classical theory for traveling waves for the F–KPP with constant coefficients.

Previous works focused on the qualitative problem that asks whether an input program terminates with probability~1 (almost-sure termination). A powerful approach for this qualitative problem is the notion of ranking supermartingales with respect to a given set of invariants. The quantitative problem (probabilistic termination) asks for bounds on the termination probability. A fundamental and conceptual drawback of the existing approaches to address probabilistic termination is that even though the supermartingales consider the probabilistic behavior of the programs, the invariants are obtained completely ignoring the probabilistic aspect. In this work we address the probabilistic termination problem for linear-arithmetic probabilistic programs with nondeterminism. We define the notion of {\\em stochastic invariants}, which are constraints along with a probability bound that the constraints hold. We introduce a concept of {\\em repulsing supermartingales}. First, we show that repulsing supermartingales can be used to obtain bounds on the probability of the stochastic invariants. Second, we show the effectiveness of repulsing supermartingales in the following three ways: (1)~With a combination of ranking and repulsing supermartingales we can compute lower bounds on the probability of termination; (2)~repulsing supermartingales provide witnesses for refutation of almost-sure termination; and (3)~with a combination of ranking and repulsing supermartingales we can establish persistence properties of probabilistic programs. We also present results on related computational problems and an experimental evaluation of our approach on academic examples.

The model-measuring problem presupposes a distance function on models. We concentrate on . automatic distance functions, which are defined by weighted automata. The model-measuring problem subsumes several generalizations of the classical model-checking problem, in particular, quantitative model-checking problems that measure the degree of satisfaction of a specification; robustness problems that measure how much a model can be perturbed without violating the specification; and parameter synthesis for hybrid systems. We show that for automatic distance functions, and (a) . ω-regular linear-time, (b) . ω-regular branching-time, and (c) hybrid specifications, the model-measuring problem can be solved.We use automata-theoretic model-checking methods for model measuring, replacing the emptiness question for word, tree, and hybrid automata by the . optimal-value question for the weighted versions of these automata. For automata over words and trees, we consider weighted automata that accumulate weights by maximizing, summing, discounting, and limit averaging. For hybrid automata, we consider monotonic (parametric) hybrid automata, a hybrid counterpart of (discrete) weighted automata.We give several examples of using the model-measuring problem to compute various notions of robustness and quantitative satisfaction for temporal specifications. Further, we propose the modeling framework for model measuring to ease the specification and reduce the likelihood of errors in modeling.Finally, we present a variant of the model-measuring problem, called the . model-repair problem. The model-repair problem applies to models that do not satisfy the specification; it can be used to derive restrictions, under which the model satisfies the specification, i.e., to repair the model.","lang":"eng"}],"citation":{"apa":"Henzinger, T.

This is typically justified by assuming a very large number of loci with additive effects. However, it applies even when genes interact, provided that the number of loci is large enough that selection on each of them is weak relative to random drift. In the long term, directional selection will change allele frequencies, but even then, the effects of epistasis on the ultimate change in trait mean due to selection may be modest. Stabilising selection can maintain many traits close to their optima, even when the underlying alleles are weakly selected. However, the number of traits that can be optimised is apparently limited to ~4Ne by the ‘drift load’, and this is hard to reconcile with the apparent complexity of many organisms. Just as for the mutation load, this limit can be evaded by a particular form of negative epistasis. A more robust limit is set by the variance in reproductive success. This suggests that selection accumulates information most efficiently in the infinitesimal regime, when selection on individual alleles is weak, and comparable with random drift. A review of evidence on selection strength suggests that although most variance in fitness may be because of alleles with large Nes, substantial amounts of adaptation may be because of alleles in the infinitesimal regime, in which epistasis has modest effects."}],"scopus_import":"1","citation":{"chicago":"Barton, Nicholas H. “How Does Epistasis Influence the Response to Selection?” <i>Heredity</i>.

Maximum likelihood estimation for this class of models leads to a non-convex optimization problem which typically has many local maxima. Using recent results on the asymptotic distribution of extreme eigenvalues of the Wishart distribution, we provide sufficient conditions for any hill climbing method to converge to the global maximum. Although we are primarily interested in the case in which n≫p, the proofs of our results utilize large sample asymptotic theory under the scheme n/p→γ&gt;1. Remarkably, our numerical simulations indicate that our results remain valid for p as small as 2. An important consequence of this analysis is that, for sample sizes n≃14p, maximum likelihood estimation for linear Gaussian covariance models behaves as if it were a convex optimization problem. © 2016 The Royal Statistical Society and Blackwell Publishing Ltd."}],"scopus_import":"1","type":"journal_article","project":[{"_id":"2530CA10-B435-11E9-9278-68D0E5697425","name":"Gaussian Graphical Models: Theory and Applications","call_identifier":"FWF","grant_number":"Y 903-N35"}],"publication_status":"published","title":"Maximum likelihood estimation for linear Gaussian covariance models","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","author":[{"full_name":"Zwiernik, Piotr","first_name":"Piotr","last_name":"Zwiernik"},{"orcid":"0000-0002-7008-0216","last_name":"Uhler","id":"49ADD78E-F248-11E8-B48F-1D18A9856A87","first_name":"Caroline","full_name":"Uhler, Caroline"},{"last_name":"Richards","first_name":"Donald","full_name":"Richards, Donald"}],"publisher":"Wiley-Blackwell","language":[{"iso":"eng"}],"article_processing_charge":"No","department":[{"_id":"CaUh"}],"publist_id":"6142"}]
