How ribosome levels control stem cell differentiation is not fully known. Here, we discovered three RNA helicases are required for ribosome biogenesis and for Drosophila oogenesis. Loss of these helicases, which we named Aramis, Athos and Porthos, lead to aberrant stabilization of p53, cell cycle arrest and stalled GSC differentiation. Unexpectedly, Aramis is required for efficient translation of a cohort of mRNAs containing a 5’-Terminal-Oligo-Pyrimidine (TOP)-motif, including mRNAs that encode ribosomal proteins and a conserved p53 inhibitor, Novel Nucleolar protein 1 (Non1). The TOP-motif co-regulates the translation of growth-related mRNAs in mammals. As in mammals, the La-related protein co-regulates the translation of TOP-motif containing RNAs during Drosophila oogenesis. Thus, a previously unappreciated TOP-motif in Drosophila responds to reduced ribosome biogenesis to co-regulate the translation of ribosomal proteins and a p53 repressor, thus coupling ribosome biogenesis to GSC differentiation."}],"main_file_link":[{"url":"https://doi.org/10.1101/2021.04.04.438367","open_access":"1"}],"oa":1,"tmp":{"short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png"},"year":"2022","issue":"7","date_published":"2022-04-11T00:00:00Z","pmid":1,"publisher":"Elsevier","day":"11","_id":"10714","ec_funded":1,"article_type":"original","title":"A translation control module coordinates germline stem cell differentiation with ribosome biogenesis during Drosophila oogenesis","volume":57,"publication":"Developmental Cell","status":"public","isi":1,"type":"journal_article","oa_version":"Preprint","publication_status":"published","doi":"10.1016/j.devcel.2022.03.005","article_processing_charge":"No","author":[{"last_name":"Martin","full_name":"Martin, Elliot T.","first_name":"Elliot T."},{"first_name":"Patrick","last_name":"Blatt","full_name":"Blatt, Patrick"},{"full_name":"Ngyuen, Elaine","last_name":"Ngyuen","first_name":"Elaine"},{"first_name":"Roni","full_name":"Lahr, Roni","last_name":"Lahr"},{"full_name":"Selvam, Sangeetha","last_name":"Selvam","first_name":"Sangeetha"},{"first_name":"Hyun Ah M.","last_name":"Yoon","full_name":"Yoon, Hyun Ah M."},{"first_name":"Tyler","last_name":"Pocchiari","full_name":"Pocchiari, Tyler"},{"full_name":"Emtenani, Shamsi","last_name":"Emtenani","first_name":"Shamsi","orcid":"0000-0001-6981-6938","id":"49D32318-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Siekhaus","full_name":"Siekhaus, Daria E","first_name":"Daria E","id":"3D224B9E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8323-8353"},{"first_name":"Andrea","last_name":"Berman","full_name":"Berman, Andrea"},{"first_name":"Gabriele","last_name":"Fuchs","full_name":"Fuchs, Gabriele"},{"first_name":"Prashanth","last_name":"Rangan","full_name":"Rangan, Prashanth"}],"department":[{"_id":"DaSi"}],"date_updated":"2025-06-12T06:19:50Z","language":[{"iso":"eng"}],"citation":{"ama":"Martin ET, Blatt P, Ngyuen E, et al.

In this context, synthetic auxin analogs, such as 1-Naphtalene Acetic Acid (1-NAA), are often favored over the endogenous auxin indole-3-acetic acid (IAA), in part due to their higher stability. While such auxin analogs have proven to be instrumental to reveal the various faces of auxin, they display in some cases distinct bioactivities compared to IAA. Here, we focused on the effect of auxin analogs on the accumulation of PIN proteins in Brefeldin A-sensitive endosomal aggregations (BFA bodies), and the correlation with the ability to elicit Ca 2+ responses. For a set of commonly used auxin analogs, we evaluated if auxin-analog induced Ca 2+ signaling inhibits PIN accumulation. Not all auxin analogs elicited a Ca 2+ response, and their differential ability to elicit Ca 2+ responses correlated partially with their ability to inhibit BFA-body formation. However, in tir1/afb and cngc14, 1-NAA-induced Ca 2+ signaling was strongly impaired, yet 1-NAA still could inhibit PIN accumulation in BFA bodies. This demonstrates that TIR1/AFB-CNGC14-dependent Ca 2+ signaling does not inhibit BFA body formation in Arabidopsis roots.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://biblio.ugent.be/publication/8738721"}],"quality_controlled":"1","oa":1,"date_published":"2022-04-18T00:00:00Z","year":"2022","issue":"8","citation":{"mla":"Wang, R., et al. “Auxin Analog-Induced Ca2+ Signaling Is Independent of Inhibition of Endosomal Aggregation in Arabidopsis Roots.” Journal of Experimental Botany, vol. 73, no. 8, erac019, Oxford University Press, 2022, doi:10.1093/jxb/erac019.","ieee":"R.

We also focus on feedback inhibition mechanisms that prevent the over-amplification of auxin signals. In addition, we cover the TRANSMEMBRANE KINASEs (TMKs)-mediated non-canonical signaling, which converges with TIR1/AFBs-mediated transcriptional regulation to coordinate plant growth and development. The identification of additional auxin signaling components and their regulation will continue to open new avenues of research in this field, leading to an increasingly deeper, more comprehensive understanding of how auxin signals are interpreted at the cellular level to regulate plant growth and development."}],"date_created":"2022-02-03T09:52:59Z","intvolume":" 64","quality_controlled":"1","volume":64,"title":"Auxin signaling: Research advances over the past 30 years","article_type":"review","publication":"Journal of Integrative Plant Biology","pmid":1,"_id":"10719","day":"01","publisher":"Wiley"},{"month":"01","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","external_id":{"arxiv":["2012.15155"],"isi":["000749198000039"]},"file":[{"file_name":"2022_ScientificReports_Svoboda.pdf","date_updated":"2022-02-07T14:57:59Z","checksum":"247afd30c173390940f099ead35a28ed","relation":"main_file","file_size":2971922,"file_id":"10744","date_created":"2022-02-07T14:57:59Z","success":1,"access_level":"open_access","content_type":"application/pdf","creator":"alisjak"}],"acknowledgement":"K.C. acknowledges support from ERC Consolidator Grant No. (863818: ForM-SMart).

We track how the number of infected and critically ill people develops over time in order to estimate the demand that is imposed on the hospital system. To keep this demand under control, we consider a class of simple policies for slowing down and reopening society and we compare their efficiency in mitigating the spread of the virus from several different points of view. We find that in order to avoid overwhelming of the hospital system, a policy must impose a harsh lockdown or it must react swiftly (or both). While reacting swiftly is universally beneficial, being harsh pays off only when the country is patient about reopening and when the neighboring countries coordinate their mitigation efforts. Our work highlights the importance of acting decisively when closing down and the importance of patience and coordination between neighboring countries when reopening.","lang":"eng"}],"intvolume":" 12","quality_controlled":"1"},{"isi":1,"status":"public","doi":"10.1016/j.jfa.2022.109394","publication_status":"published","oa_version":"Published Version","type":"journal_article","author":[{"first_name":"Giorgio","orcid":"0000-0002-4901-7992","id":"42198EFA-F248-11E8-B48F-1D18A9856A87","last_name":"Cipolloni","full_name":"Cipolloni, Giorgio"},{"full_name":"Erdös, László","last_name":"Erdös","orcid":"0000-0001-5366-9603","id":"4DBD5372-F248-11E8-B48F-1D18A9856A87","first_name":"László"},{"full_name":"Schröder, Dominik J","last_name":"Schröder","id":"408ED176-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2904-1856","first_name":"Dominik J"}],"article_processing_charge":"Yes (via OA deal)","date_updated":"2024-10-09T21:01:33Z","department":[{"_id":"LaEr"}],"article_number":"109394","has_accepted_license":"1","citation":{"mla":"Cipolloni, Giorgio, et al. “Thermalisation for Wigner Matrices.” Journal of Functional Analysis, vol. 282, no. 8, 109394, Elsevier, 2022, doi:10.1016/j.jfa.2022.109394.","ieee":"G.

In this paper, we present a detailed mapping of the out-of-plane (OOP) magnetic anisotropy in Sr2IrO4 for different sample orientations using torque magnetometry measurements in the low-magnetic-field region before the isospins are completely ordered. Dominant in-plane anisotropy was identified at low fields, confirming the b axis as an easy magnetization axis. Based on the fitting analysis of the strong uniaxial magnetic anisotropy, we observed that the main anisotropic effect arises from a spin–orbit-coupled magnetic exchange interaction affecting the OOP interaction. The effect of interlayer exchange interaction results in additional anisotropic terms owing to the tilting of the isospins. The results are relevant for understanding OOP magnetic anisotropy and provide a new way to analyze the effects of spin–orbit-coupling and interlayer magnetic exchange interactions. This study provides insight into the understanding of bulk magnetic, magnetotransport, and spintronic behavior on Sr2IrO4 for future studies.","lang":"eng"}],"intvolume":" 34","issue":"13","year":"2022","date_published":"2022-01-20T00:00:00Z","oa":1,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"}},{"date_updated":"2025-03-31T16:00:23Z","department":[{"_id":"CaGu"},{"_id":"GaTk"},{"_id":"NiBa"}],"author":[{"last_name":"Lagator","full_name":"Lagator, Mato","first_name":"Mato","id":"345D25EC-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Srdjan","id":"35F0286E-F248-11E8-B48F-1D18A9856A87","last_name":"Sarikas","full_name":"Sarikas, Srdjan"},{"full_name":"Steinrück, Magdalena","last_name":"Steinrück","id":"2C023F40-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-1229-9719","first_name":"Magdalena"},{"last_name":"Toledo-Aparicio","full_name":"Toledo-Aparicio, David","first_name":"David"},{"last_name":"Bollback","full_name":"Bollback, Jonathan P","first_name":"Jonathan P","id":"2C6FA9CC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4624-4612"},{"last_name":"Guet","full_name":"Guet, Calin C","first_name":"Calin C","id":"47F8433E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6220-2052"},{"full_name":"Tkačik, Gašper","last_name":"Tkačik","first_name":"Gašper","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6699-1455"}],"article_processing_charge":"No","publication_status":"published","doi":"10.7554/eLife.64543","type":"journal_article","oa_version":"Published Version","isi":1,"status":"public","acknowledgement":"We thank Hande Acar, Nicholas H Barton, Rok Grah, Tiago Paixao, Maros Pleska, Anna Staron, and Murat Tugrul for insightful comments and input on the manuscript.

Currently, this is possible only locally in a narrow mutational neighborhood around a wildtype sequence rather than globally from any sequence. Using random mutant libraries, we developed a biophysical model that accounts for multiple features of σ70 binding bacterial promoters to predict constitutive gene expression levels from any sequence. We experimentally and theoretically estimated that 10–20% of random sequences lead to expression and ~80% of non-expressing sequences are one mutation away from a functional promoter. The potential for generating expression from random sequences is so pervasive that selection acts against σ70-RNA polymerase binding sites even within inter-genic, promoter-containing regions. This pervasiveness of σ70-binding sites implies that emergence of promoters is not the limiting step in gene regulatory evolution. Ultimately, the inclusion of novel features of promoter function into a mechanistic model enabled not only more accurate predictions of gene expression levels, but also identified that promoters evolve more rapidly than previously thought."}],"date_created":"2022-02-06T23:01:32Z","quality_controlled":"1","publication":"eLife","volume":11,"ec_funded":1,"title":"Predicting bacterial promoter function and evolution from random sequences","article_type":"original","_id":"10736","publisher":"eLife Sciences Publications","day":"26","ddc":["576"],"pmid":1},{"date_published":"2022-01-14T00:00:00Z","issue":"1","year":"2022","oa":1,"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1404.5475"}],"date_created":"2022-02-06T23:01:32Z","intvolume":" 26","abstract":[{"text":"We consider two models for the sequence labeling (tagging) problem.

The second model is a Weighted Context-Free Grammar (WCFG) frequently used for natural language processing. PB and WCFG encode local and non-local interactions respectively, and thus can be viewed as complementary. We propose a Grammatical Pattern-Based CRF model (GPB) that combines the two in a natural way. We argue that it has certain advantages over existing approaches such as the Hybrid model of Benedí and Sanchez that combines N-grams and WCFGs. The focus of this paper is to analyze the complexity of inference tasks in a GPB such as computing MAP. We present a polynomial-time algorithm for general GPBs and a faster version for a special case that we call Interaction Grammars.","lang":"eng"}],"quality_controlled":"1","publication":"Intelligent Data Analysis","volume":26,"title":"Combining pattern-based CRFs and weighted context-free grammars","article_type":"original","_id":"10737","day":"14","publisher":"IOS Press","arxiv":1,"date_updated":"2024-10-09T21:01:33Z","department":[{"_id":"VlKo"}],"author":[{"full_name":"Takhanov, Rustem","last_name":"Takhanov","first_name":"Rustem","id":"2CCAC26C-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Kolmogorov","full_name":"Kolmogorov, Vladimir","id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","first_name":"Vladimir"}],"article_processing_charge":"No","doi":"10.3233/IDA-205623","publication_status":"published","oa_version":"Preprint","type":"journal_article","isi":1,"status":"public","external_id":{"arxiv":["1404.5475"],"isi":["000749997700015"]},"page":"257-272","publication_identifier":{"eissn":["1571-4128"],"issn":["1088-467X"]},"month":"01","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","scopus_import":"1","corr_author":"1","citation":{"ieee":"R.

In particular social media platforms provide rich sources of user-generated data, though typically in unstructured form, and with high diversity, such as written in many different languages. Automatically identifying meaningful information in such big data resources and extracting it efficiently is one of the ongoing challenges of our time. A common step for this is sentiment analysis, which forms the foundation for tasks such as opinion mining or trend prediction. Unfortunately, publicly available tools for this task are almost exclusively available for English-language texts. Consequently, a large fraction of the Internet users, who do not communicate in English, are ignored in automatized studies, a phenomenon called rare-language discrimination.In this work we propose a technique to overcome this problem by a truly multi-lingual model, which can be trained automatically without linguistic knowledge or even the ability to read the many target languages. The main step is to combine self-annotation, specifically the use of emoticons as a proxy for labels, with multi-lingual sentence representations.To evaluate our method we curated several large datasets from data obtained via the free Twitter streaming API. The results show that our proposed multi-lingual training is able to achieve sentiment predictions at the same quality level for rare languages as for frequent ones, and in particular clearly better than what mono-lingual training achieves on the same data.

We previously reported that store-operated Ca2+ entry (SOCE) blockers, such as RP4010, are promising antitumor drugs for esophageal cancer. As a tyrosine kinase inhibitor (TKI), afatinib received FDA approval to be used in targeted therapy for patients with EGFR mutation-positive cancers. While preclinical studies and clinical trials have shown that afatinib has benefits for esophageal cancer patients, it is not known whether a combination of afatinib and RP4010 could achieve better anticancer effects. Since TKI can alter intracellular Ca2+ dynamics through EGFR/phospholipase C-γ pathway, in this study, we evaluated the inhibitory effect of afatinib and RP4010 on intracellular Ca2+ oscillations in KYSE-150, a human esophageal squamous cell carcinoma cell line, using both experimental and mathematical simulations. Our mathematical simulation of Ca2+ oscillations could fit well with experimental data responding to afatinib or RP4010, both separately or in combination. Guided by simulation, we were able to identify a proper ratio of afatinib and RP4010 for combined treatment, and such a combination presented synergistic anticancer-effect evidence by experimental measurement of intracellular Ca2+ and cell proliferation. This intracellular Ca2+ dynamic-based mathematical simulation approach could be useful for a rapid and cost-effective evaluation of combined targeting therapy drugs."}],"intvolume":" 23","date_created":"2022-02-13T23:01:35Z","quality_controlled":"1"},{"status":"public","oa_version":"Published Version","type":"journal_article","doi":"10.1088/1751-8121/ac3947","publication_status":"published","author":[{"full_name":"Feliciangeli, Dario","last_name":"Feliciangeli","first_name":"Dario","id":"41A639AA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0754-8530"},{"first_name":"Simone Anna Elvira","orcid":"0000-0001-5059-4466","id":"856966FE-A408-11E9-977E-802DE6697425","last_name":"Rademacher","full_name":"Rademacher, Simone Anna Elvira"},{"full_name":"Seiringer, Robert","last_name":"Seiringer","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6781-0521","first_name":"Robert"}],"article_processing_charge":"Yes (via OA deal)","department":[{"_id":"RoSe"}],"date_updated":"2025-04-15T06:54:54Z","language":[{"iso":"eng"}],"article_number":"015201","has_accepted_license":"1","citation":{"ieee":"D.

Our results demonstrate that 5caC has a pH-dependent global destabilizing and a base-pair mobility enhancing local impact on dsDNA, albeit without any detectable influence on the ground-state B-DNA structure. Measurement of hybridization thermodynamics and kinetics of 5caC-bearing DNA duplexes highlighted how acidic environment (pH 5.8 and 4.7) destabilizes the double-stranded structure by ∼10–20 kJ mol–1 at 37 °C when compared to the same sample at neutral pH. Protonation of 5caC results in a lower activation energy for the dissociation process and a higher barrier for annealing. Studies on conformational exchange on the microsecond time scale regime revealed a sharply localized base-pair motion involving exclusively the modified site and its immediate surroundings. By direct comparison with canonical and 5-formylcytosine (5fC)-edited strands, we were able to address the impact of the two most oxidized naturally occurring cytosine derivatives in the genome. These insights on 5caC’s subtle sensitivity to acidic pH contribute to the long-standing questions of its capacity as a substrate in base excision repair processes and its purpose as an independent, stable epigenetic mark."}],"title":"1H NMR chemical exchange techniques reveal local and global effects of oxidized cytosine derivatives","article_type":"original","volume":2,"publication":"ACS Physical Chemistry Au","pmid":1,"ddc":["540"],"day":"11","publisher":"American Chemical Society","_id":"10758"},{"volume":398,"title":"Arithmetic purity of the Hardy-Littlewood property and geometric sieve for affine quadrics","article_type":"original","publication":"Advances in Mathematics","_id":"10765","day":"26","arxiv":1,"publisher":"Elsevier","oa":1,"date_published":"2022-03-26T00:00:00Z","issue":"3","year":"2022","main_file_link":[{"url":"https://arxiv.org/abs/2003.07287","open_access":"1"}],"abstract":[{"text":"We establish the Hardy-Littlewood property (à la Borovoi-Rudnick) for Zariski open subsets in affine quadrics of the form q(x1,...,xn)=m, where q is a non-degenerate integral quadratic form in n>3 variables and m is a non-zero integer.

Once established, the channels provide positional information, along which new vascular strands form, for example, during organogenesis, regeneration, or leave venation. The main prerequisite of this still mysterious auxin canalization mechanism is a feedback between auxin signaling and its directional transport. This is manifested by auxin-induced re-arrangements of polar, subcellular localization of PIN-FORMED (PIN) auxin exporters. Immanent open questions relate to how position of auxin source and sink as well as tissue context are sensed and translated into tissue polarization and how cells communicate to polarize coordinately.

Our main result states that there exist Reed–Solomon codes with rate Ω(ε) which are (1 - ε, O(1/ε))-list-decodable, meaning that any Hamming ball of radius 1-ε contains at most O(1/ε) codewords. This trade-off between rate and list-decoding radius is best-possible for any code with list size less than exponential in the block length.

Moreover, while their result requires the field to be exponentially large in the block length, we only need the field size to be polynomially large (and in fact, almost-linear suffices).

Given a point p in the interior of K, a hyperplane h passing through p is called barycentric if p is the barycenter of K∩h. In 1961, Grünbaum raised the question whether, for every K, there exists an interior point p through which there are at least n+1 distinct barycentric hyperplanes. Two years later, this was seemingly resolved affirmatively by showing that this is the case if p=p0 is the point of maximal depth in K. However, while working on a related question, we noticed that one of the auxiliary claims in the proof is incorrect. Here, we provide a counterexample; this re-opens Grünbaum’s question. It follows from known results that for n≥2, there are always at least three distinct barycentric cuts through the point p0∈K of maximal depth. Using tools related to Morse theory we are able to improve this bound: four distinct barycentric cuts through p0 are guaranteed if n≥3."}],"date_created":"2022-02-20T23:01:35Z","intvolume":" 68","year":"2022","date_published":"2022-12-01T00:00:00Z","oa":1,"day":"01","publisher":"Springer Nature","arxiv":1,"_id":"10776","publication":"Discrete and Computational Geometry","article_type":"original","title":"Barycentric cuts through a convex body","volume":68}]
