Retinal ischemia is involved in enormous pathological processes including oxidative stress, reactive gliosis, and retinal functional deficits. Thus, maintaining retinal function by modulating those pathological processes may prevent or protect against vision loss. Over the decades, nicotinamide mononucleotide (NMN), a crucial nicotinamide adenine dinucleotide (NAD+) intermediate, has been nominated as a promising therapeutic target in retinal diseases. Nonetheless, a protective effect of NMN has not been examined in cardiovascular diseases-induced retinal ischemia. In our study, we aimed to investigate its promising effect of NMN in the ischemic retina of a murine model of carotid artery occlusion. After surgical unilateral common carotid artery occlusion (UCCAO) in adult male C57BL\/6 mice, NMN (500 mg\/kg\/day) was intraperitoneally injected to mice every day until the end of experiments. Electroretinography and biomolecular assays were utilized to measure ocular functional and further molecular alterations in the retina. We found that UCCAO-induced retinal dysfunction was suppressed, pathological gliosis was reduced, retinal NAD+ levels were preserved, and the expression of an antioxidant molecule (nuclear factor erythroid-2-related factor 2; Nrf2) was upregulated by consecutive administration of NMN. Our present outcomes first suggest a promising NMN therapy for the suppression of cardiovascular diseases-mediated retinal ischemic dysfunction.<\/jats:p>","DOI":"10.3390\/ijms232314711","type":"journal-article","created":{"date-parts":[[2022,11,25]],"date-time":"2022-11-25T02:05:37Z","timestamp":1669341937000},"page":"14711","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Nicotinamide Mononucleotide Protects against Retinal Dysfunction in a Murine Model of Carotid Artery Occlusion"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5992-9039","authenticated-orcid":false,"given":"Deokho","family":"Lee","sequence":"first","affiliation":[{"name":"Laboratory of Photobiology, Keio University School of Medicine, Tokyo 160-8582, Japan"},{"name":"Department of Ophthalmology, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1013-5737","authenticated-orcid":false,"given":"Yohei","family":"Tomita","sequence":"additional","affiliation":[{"name":"Laboratory of Photobiology, Keio University School of Medicine, Tokyo 160-8582, Japan"},{"name":"Department of Ophthalmology, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5377-6772","authenticated-orcid":false,"given":"Yukihiro","family":"Miwa","sequence":"additional","affiliation":[{"name":"Laboratory of Photobiology, Keio University School of Medicine, Tokyo 160-8582, Japan"},{"name":"Department of Ophthalmology, Keio University School of Medicine, Tokyo 160-8582, Japan"},{"name":"Aichi Animal Eye Clinic, Nagoya 466-0827, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heonuk","family":"Jeong","sequence":"additional","affiliation":[{"name":"Laboratory of Photobiology, Keio University School of Medicine, Tokyo 160-8582, Japan"},{"name":"Department of Ophthalmology, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2322-0332","authenticated-orcid":false,"given":"Ari","family":"Shinojima","sequence":"additional","affiliation":[{"name":"Laboratory of Photobiology, Keio University School of Medicine, Tokyo 160-8582, Japan"},{"name":"Department of Ophthalmology, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norimitsu","family":"Ban","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4917-033X","authenticated-orcid":false,"given":"Shintaro","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ken","family":"Nishioka","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2892-9810","authenticated-orcid":false,"given":"Kazuno","family":"Negishi","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9833-4356","authenticated-orcid":false,"given":"Jun","family":"Yoshino","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5457-2720","authenticated-orcid":false,"given":"Toshihide","family":"Kurihara","sequence":"additional","affiliation":[{"name":"Laboratory of Photobiology, Keio University School of Medicine, Tokyo 160-8582, Japan"},{"name":"Department of Ophthalmology, Keio University School of Medicine, Tokyo 160-8582, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Vilares-Morgado, R., Nunes, H.M.M., Dos Reis, R.S., and Barbosa-Breda, J.
