We previously showed that exposure of mouse sires to AA for three consecutive generations induces a cumulative change in fatty acid (FA) involved in inflammation and an increase in body and liver weight in the offspring. Here, we tested the hypothesis that paternal AA exposure changes the progeny\u2019s behavioral response to a proinflammatory insult, and asked whether tissue-specific FA are associated with that response. Male BALB\/c mice were supplemented daily with three doses of AA for 10 days and crossed to non-supplemented females (n = 3\/dose). Two-month-old unsupplemented male and female offspring (n = 6\/paternal AA dose) were exposed to Gram-negative bacteria-derived lipopolysaccharides (LPS) or saline control two hours prior to open field test (OFT) behavioral analysis and subsequent sacrifice. We probed for significant effects of paternal AA exposure on: OFT behaviors; individual FA content of blood, hypothalamus and hypothalamus-free brain; hypothalamic expression profile of genes related to inflammation (\n                    <jats:italic>Tnfa<\/jats:italic>\n                    ,\n                    <jats:italic>Il1b<\/jats:italic>\n                    ,\n                    <jats:italic>Cox1<\/jats:italic>\n                    ,\n                    <jats:italic>Cox2<\/jats:italic>\n                    ) and FA synthesis (\n                    <jats:italic>Scd1<\/jats:italic>\n                    ,\n                    <jats:italic>Elovl6<\/jats:italic>\n                    ). All parameters were affected by paternal AA supplementation in a sex-specific manner. Paternal AA primed the progeny for behavior associated with increased anxiety, with a marked sex dimorphism: high AA doses acted as surrogate of LPS in males, realigning a number of OFT behaviors that in females were differential between saline and LPS groups. Progeny hypothalamic\n                    <jats:italic>Scd1<\/jats:italic>\n                    , a FA metabolism enzyme with documented pro-inflammatory activity, showed a similar pattern of differential expression between saline and LPS groups at high paternal AA dose in females, that was blunted in males. Progeny FA generally were not affected by LPS, but displayed non-linear associations with paternal AA doses. In conclusion, we document that paternal exposure to AA exerts long-term behavioral and biochemical effects in the progeny in a sex-specific manner.\n                  <\/jats:p>","DOI":"10.1371\/journal.pone.0300141","type":"journal-article","created":{"date-parts":[[2024,3,21]],"date-time":"2024-03-21T13:27:51Z","timestamp":1711027671000},"page":"e0300141","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":2,"title":["Effects of paternal arachidonic acid supplementation on offspring behavior and hypothalamus inflammation markers in the mouse"],"prefix":"10.1371","volume":"19","author":[{"given":"Atenea","family":"V\u00e1zquez-S\u00e1nchez","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dalia","family":"Rodr\u00edguez-R\u00edos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dannia","family":"Col\u00edn-Castel\u00e1n","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"Molina-Torres","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enrique","family":"Ram\u00edrez-Ch\u00e1vez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gloria del Carmen","family":"Romo-Morales","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvio","family":"Zaina","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3556-8520","authenticated-orcid":true,"given":"Gertrud","family":"Lund","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2024,3,21]]},"reference":[{"key":"pone.0300141.ref001","doi-asserted-by":"crossref","DOI":"10.1186\/s12944-019-1039-y","article-title":"Intake of arachidonic acid-containing lipids in adult humans: dietary surveys and clinical trials","volume":"18","author":"H.
