Numerous studies have reported the benefits of docosahexaenoic acid (DHA) on neurodevelopment and cognitive ability, while comparatively less attention has been given to eicosapentaenoic acid (EPA). Additionally, little is known about the effects and mechanisms of DHA and EPA in relation to seizure-induced cognitive impairment in the young rodent model. Current research indicates that ferroptosis is involved in epilepsy and cognitive deficiency in children. Further investigation is warranted to determine whether EPA or DHA can mitigate seizure-induced cognitive deficits by inhibiting ferroptosis. Therefore, this study was conducted to compare the effects of DHA and EPA on seizure-induced cognitive deficiency and reveal the underlying mechanisms focused on ferroptosis in a pentylenetetrazol (PTZ)-kindling young mice model. Mice were fed a diet containing DHA-enriched ethyl esters or EPA-enriched ethyl esters for 21 days at the age of 3 weeks and treated with PTZ (35 mg\/kg, i.p.) every other day 10 times. The findings indicated that both EPA and DHA exhibited ameliorative effects on seizure-induced cognitive impairment, with EPA demonstrating a superior efficacy. Further mechanism study revealed that supplementation of DHA and EPA significantly increased cerebral DHA and EPA levels, balanced neurotransmitters, and inhibited ferroptosis by modulating iron homeostasis and reducing lipid peroxide accumulation in the hippocampus through activating the Nrf2\/Sirt3 signal pathway. Notably, EPA exhibited better an advantage in ameliorating iron dyshomeostasis compared to DHA, owing to its stronger upregulation of Sirt3. These results indicate that DHA and EPA can efficaciously alleviate seizure-induced cognitive deficiency by inhibiting ferroptosis in PTZ-kindled young mice.<\/jats:p>","DOI":"10.3390\/md21090464","type":"journal-article","created":{"date-parts":[[2023,8,25]],"date-time":"2023-08-25T08:42:20Z","timestamp":1692952940000},"page":"464","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["A Compared Study of Eicosapentaenoic Acid and Docosahexaenoic Acid in Improving Seizure-Induced Cognitive Deficiency in a Pentylenetetrazol-Kindling Young Mice Model"],"prefix":"10.3390","volume":"21","author":[{"given":"Yueqi","family":"Yang","sequence":"first","affiliation":[{"name":"Institute of Biopharmaceutical Research, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueyan","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Biopharmaceutical Research, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Biopharmaceutical Research, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiben","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Pharmaceutical Sciences, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Han","sequence":"additional","affiliation":[{"name":"Institute of Biopharmaceutical Research, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengping","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Biopharmaceutical Research, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8897-1239","authenticated-orcid":false,"given":"Min","family":"Wen","sequence":"additional","affiliation":[{"name":"Institute of Biopharmaceutical Research, Liaocheng University, Liaocheng 252059, China"},{"name":"Pet Nutrition Research and Development Center, Gambol Pet Group Co., Ltd., Liaocheng 252000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e20163908","DOI":"10.1542\/peds.2016-3908","article-title":"Incidence and Prevalence of Childhood Epilepsy: A Nationwide Cohort Study","volume":"139","author":"Aaberg","year":"2017","journal-title":"Pediatrics"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Ren, Y., Pan, L., Du, X., Hou, Y., Li, X., and Song, Y.
