To address these challenges, we introduce mulea, an R package offering comprehensive overrepresentation and functional enrichment analysis. mulea employs an innovative empirical false discovery rate (eFDR) correction method, specifically designed for interconnected biological data, to accurately identify significant terms within diverse ontologies. mulea expands beyond traditional tools by incorporating a wide range of ontologies, encompassing Gene Ontology, pathways, regulatory elements, genomic locations, and protein domains. This flexibility enables researchers to tailor enrichment analysis to their specific questions, such as identifying enriched transcriptional regulators in gene expression data or overrepresented protein domains in protein sets. To facilitate seamless analysis, mulea provides gene sets (in standardised GMT format) for 27 model organisms, covering 16 databases and various identifiers resulting in almost 900 files. Additionally, the muleaData ExperimentData Bioconductor package simplifies access to these pre-defined ontologies. Finally, mulea's architecture allows for easy integration of user-defined ontologies, expanding its applicability across diverse research areas.

Our results indicate the presence of high steppe ancestry in the Somogyvár-Vinkovci culture. They were then replaced by the Kisapostag group, who exhibit an outstandingly high (up to ∼47%) Mesolithic hunter-gatherer ancestry, despite this component being thought to be highly diluted by the time of the Early Bronze Age. The Kisapostag population contributed the genetic basis for the succeeding community of the Encrusted pottery culture. We also found an elevated hunter-gatherer component in a local Baden culture associated individual, but no connections were proven to the Bronze Age individuals. The hunter-gatherer ancestry in Kisapostag is likely derived from two main sources, one from a Funnelbeaker or Globular Amphora culture related population and one from a previously unrecognised source in Eastern Europe. We show that this ancestry not only appeared in various groups in Bronze Age Central Europe, but also made contributions to Baltic populations. The social structure of Kisapostag and Encrusted pottery cultures is patrilocal, similarly to most contemporaneous groups. Furthermore, we developed new methods and method standards for computational analyses of ancient DNA, implemented to our newly developed and freely available bioinformatic package. By analysing clinical traits, we found carriers of aneuploidy and inheritable genetic diseases.

In the potentially immortal germline, TEs are effectively suppressed by the Piwi-piRNA pathway. However, in the genomes of ageing somatic cells lacking the effects of the pathway, TEs become increasingly mobile during the adult lifespan, and their activity is associated with genomic instability. Whether the progressively increasing mobilization of TEs is a cause or a consequence of ageing remains a fundamental problem in biology. Here we show that in the nematode Caenorhabditis elegans , the downregulation of active TE families extends lifespan. Ectopic activation of Piwi proteins in the soma also promotes longevity. Furthermore, DNA N 6 -adenine methylation at TE stretches gradually rises with age, and this epigenetic modification elevates their transcription as the animal ages. These results indicate that TEs represent a novel genetic determinant of ageing, and that N 6 -adenine methylation plays a pivotal role in ageing control.}, year = {2023}, eissn = {2041-1723}, orcid-numbers = {Sturm, Ádám/0000-0002-9515-8761; Saskői, Éva/0000-0001-6691-8576; Hotzi, Bernadette/0000-0003-1433-6843; Barna, János/0000-0002-9242-0939; Bodnár, Ferenc/0000-0001-9630-1315; Sharma, Himani/0000-0001-6947-9281; Kovács, Tibor/0000-0002-0632-9128; Ari, Eszter/0000-0001-7774-1067; Kerepesi, Csaba/0000-0001-9541-246X; Perczel, András/0000-0003-1252-6416; Ivics, Zoltán/0000-0002-7803-6658; Vellai, Tibor/0000-0002-3520-2572} } @article{MTMT:33040340, title = {A Single Early Introduction Governed Viral Diversity in the Second Wave of SARS-CoV-2 Epidemic in Hungary}, url = {https://m2.mtmt.hu/api/publication/33040340}, author = {Ari, Eszter and Vásárhelyi, Bálint Márk and Kemenesi, Gábor and Tóth, Gábor Endre and Zana, Brigitta and Somogyi, Balázs Antal and Lanszki, Zsófia and Röst, Gergely and Jakab, Ferenc and Papp, Balázs and Kintses, Bálint}, doi = {10.1093/ve/veac069}, journal-iso = {VIRUS EVOL}, journal = {VIRUS EVOLUTION}, volume = {8}, unique-id = {33040340}, abstract = {Retrospective evaluation of past waves of the SARS-CoV-2 epidemic is key for designing optimal interventions against future waves and novel pandemics. Here we report on analysing genome sequences of SARS-CoV-2 from the first two waves of the epidemic in 2020 in Hungary, mirroring a suppression and a mitigation strategy, respectively. Our analysis reveals that the two waves markedly differed in viral diversity and transmission patterns. Specifically, unlike in several European areas or in the USA, we have found no evidence for early introduction and cryptic transmission of the virus in the first wave of the pandemic in Hungary. Despite the introduction of multiple viral lineages, extensive community spread was prevented by a timely national lockdown in March 2020. In sharp contrast, the majority of the cases in the much larger second wave can be linked to a single transmission lineage of the pan-European B.1.160 variant. This lineage was introduced unexpectedly early, followed by a two-month-long cryptic transmission before a soar of detected cases in September 2020. Epidemic analysis has revealed that the dominance of this lineage in the second wave was not associated with an intrinsic transmission advantage. This finding is further supported by the rapid replacement of B.1.160 by the alpha variant (B.1.1.7) that launched the third wave of the epidemic in February 2021. Overall, these results illustrate how the founder effect in combination with cryptic transmission, instead of repeated international introductions or higher transmissibility, can govern viral diversity.}, year = {2022}, eissn = {2057-1577}, orcid-numbers = {Ari, Eszter/0000-0001-7774-1067; Vásárhelyi, Bálint Márk/0000-0003-1782-8691; Kemenesi, Gábor/0000-0001-9775-3065; Tóth, Gábor Endre/0000-0002-7201-9646; Lanszki, Zsófia/0000-0003-3116-4633; Röst, Gergely/0000-0001-9476-3284} } @article{MTMT:32352175, title = {SignaLink3: a multi-layered resource to uncover tissue-specific signaling networks}, url = {https://m2.mtmt.hu/api/publication/32352175}, author = {Csabai, Luca and Fazekas, Dávid and Kadlecsik, Tamás and Szalay-Bekő, Máté and Bohár, Balázs and Madgwick, Matthew and Módos, Dezső and Ölbei, Márton and Gul, Lejla and Sudhakar, Padhmanand and Kubisch, János and James Oyeyemi, Oyebode and Liska, Orsolya and Ari, Eszter and Hotzi, Bernadette and Billes, Viktor András and Molnár, Eszter and Földvári-Nagy, László and Csályi, Kitti and Demeter, Amanda and Pápai, Nóra and Koltai, Mihály and Varga, Máté and Földvári-Nagy Lászlóné Lenti, Katalin and J Farkas, Illés and Türei, Dénes and Csermely, Péter and Vellai, Tibor and Korcsmáros, Tamás}, doi = {10.1093/nar/gkab909}, journal-iso = {NUCLEIC ACIDS RES}, journal = {NUCLEIC ACIDS RESEARCH}, volume = {50}, unique-id = {32352175}, issn = {0305-1048}, abstract = {Signaling networks represent the molecular mechanisms controlling a cell's response to various internal or external stimuli.
