Rats under urethane anesthesia were implanted with stimulating electrodes in the ventral hippocampal commissure and dMSA and a recording electrode in the CA1 area of the hippocampus. We found that high-frequency stimulation (HFS) of the dMSA led to the induction of long-term potentiation in the synapses formed by the ventral hippocampal commissure on the hippocampal CA1 neurons. One hour after dMSA HFS, we collected the dorsal and ventral hippocampi on both the ipsilateral (damaged by the implanted electrode) and contralateral (intact) sides and analyzed the expression of genes by qPCR. The dMSA HFS led to an increase in the expression of bdnf and cyr61 in the ipsilateral hippocampi and egr1 in the ventral contralateral hippocampus. Thus, dMSA HFS under the conditions of degeneration of the cholinergic neurons in the medial septal area prevented the described increase in gene expression. The changes in cyr61 expression appeared to be dependent on the muscarinic M1 receptors. Our data suggest that the induction of long-term potentiation by dMSA activation enhances the expression of select early genes in the hippocampus.<\/jats:p>","DOI":"10.3390\/ijms241612970","type":"journal-article","created":{"date-parts":[[2023,8,21]],"date-time":"2023-08-21T01:33:11Z","timestamp":1692581591000},"page":"12970","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Induction of Long-Term Potentiation by Medial Septum Activation under Urethane Anesthesia Can Alter Gene Expression in the Hippocampus"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8010-339X","authenticated-orcid":false,"given":"Yulia V.","family":"Dobryakova","sequence":"first","affiliation":[{"name":"Institute of Higher Nervous Activity and Neurophysiology, Russian Academy of Sciences, 117485 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantin","family":"Gerasimov","sequence":"additional","affiliation":[{"name":"Institute of Higher Nervous Activity and Neurophysiology, Russian Academy of Sciences, 117485 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulia S.","family":"Spivak","sequence":"additional","affiliation":[{"name":"Institute of Higher Nervous Activity and Neurophysiology, Russian Academy of Sciences, 117485 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tinna","family":"Korotkova","sequence":"additional","affiliation":[{"name":"Institute of Higher Nervous Activity and Neurophysiology, Russian Academy of Sciences, 117485 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alena","family":"Koryagina","sequence":"additional","affiliation":[{"name":"Institute of Higher Nervous Activity and Neurophysiology, Russian Academy of Sciences, 117485 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelina","family":"Deryabina","sequence":"additional","affiliation":[{"name":"Institute of Higher Nervous Activity and Neurophysiology, Russian Academy of Sciences, 117485 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladimir A.","family":"Markevich","sequence":"additional","affiliation":[{"name":"Institute of Higher Nervous Activity and Neurophysiology, Russian Academy of Sciences, 117485 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexey P.","family":"Bolshakov","sequence":"additional","affiliation":[{"name":"Institute of Higher Nervous Activity and Neurophysiology, Russian Academy of Sciences, 117485 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1917","DOI":"10.1093\/brain\/awy132","article-title":"The cholinergic system in the pathophysiology and treatment of Alzheimer\u2019s disease","volume":"141","author":"Hampel","year":"2018","journal-title":"Brain"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"647","DOI":"10.1111\/nan.12513","article-title":"Review: Revisiting the human cholinergic nucleus of the diagonal band of Broca","volume":"44","author":"Liu","year":"2018","journal-title":"Neuropathol.
