Cystathionine-\u03b2-synthase (CBS) and cystathionine-\u03b3-lyase (CSE) enzymes play a central role in H2S production and metabolism. Here, we investigated the role of H2S in learning and memory processes by exploring several Drosophila melanogaster strains with single and double deletions of CBS and CSE developed by the CRISPR\/Cas9 technique. We monitored the learning and memory parameters of these strains using the mating rejection courtship paradigm and demonstrated that the deletion of the CBS gene, which is expressed predominantly in the central nervous system, and double deletions completely block short- and long-term memory formation in fruit flies. On the other hand, the flies with CSE deletion preserve short- and long-term memory but fail to exhibit long-term memory retention. Transcriptome profiling of the heads of the males from the strains with deletions in Gene Ontology terms revealed a strong down-regulation of many genes involved in learning and memory, reproductive behavior, cognition, and the oxidation\u2013reduction process in all strains with CBS deletion, indicating an important role of the hydrogen sulfide production in these vital processes.<\/jats:p>","DOI":"10.3390\/biom12060751","type":"journal-article","created":{"date-parts":[[2022,5,26]],"date-time":"2022-05-26T08:50:22Z","timestamp":1653555022000},"page":"751","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Genes Responsible for H2S Production and Metabolism Are Involved in Learning and Memory in Drosophila melanogaster"],"prefix":"10.3390","volume":"12","author":[{"given":"Olga G.","family":"Zatsepina","sequence":"first","affiliation":[{"name":"Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9436-9081","authenticated-orcid":false,"given":"Lyubov N.","family":"Chuvakova","sequence":"additional","affiliation":[{"name":"Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ekaterina A.","family":"Nikitina","sequence":"additional","affiliation":[{"name":"Department of Neurogenetics, Pavlov Institute of Physiology, 199034 Saint Petersburg, Russia"},{"name":"Department of Human and Animal Anatomy and Physiology, Herzen State Pedagogical University, 191186 Saint Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander P.","family":"Rezvykh","sequence":"additional","affiliation":[{"name":"Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexey S.","family":"Zakluta","sequence":"additional","affiliation":[{"name":"Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svetlana V.","family":"Sarantseva","sequence":"additional","affiliation":[{"name":"Petersburg Institute of Nuclear Physics, Russian Academy of Sciences, 188300 Gatchina, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7863-1748","authenticated-orcid":false,"given":"Nina V.","family":"Surina","sequence":"additional","affiliation":[{"name":"Petersburg Institute of Nuclear Physics, Russian Academy of Sciences, 188300 Gatchina, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1585-7907","authenticated-orcid":false,"given":"Alexander L.","family":"Ksenofontov","sequence":"additional","affiliation":[{"name":"Belozersky Institute of Physico-Chemical Biology, Lomonosov Moscow State University, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ludmila A.","family":"Baratova","sequence":"additional","affiliation":[{"name":"Belozersky Institute of Physico-Chemical Biology, Lomonosov Moscow State University, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Viktoria Y.","family":"Shilova","sequence":"additional","affiliation":[{"name":"Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael B.","family":"Evgen\u2019ev","sequence":"additional","affiliation":[{"name":"Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"492","DOI":"10.1016\/j.neuint.2013.09.003","article-title":"Physiological role of hydrogen sulfide and polysulfide in the central nervous system","volume":"63","author":"Kimura","year":"2013","journal-title":"Neurochem.
