The retinal neovasculature was histologically evaluated, and comprehensive transcriptome analysis was conducted.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Compared to OIR neonates with normal birth weight, significant amelioration of the neovasculature, as indicated by decreases in the number of branch junctions, vascular distribution, maximal vascular radius and microaneurysm-like tufts, was observed in OIR mice with FGR. The results of retinal RNA-sequencing revealed downregulation of angiogenic factors that trigger pathological retinal neovascularization, such as the mitogen-activated protein kinase pathway and corresponding upstream signaling pathways in OIR mice with FGR.<\/jats:p><jats:p><jats:bold>Conclusion<\/jats:bold>: Our findings demonstrated that FGR neonates have a higher capacity for retinal oxygen stress, and the risk of OIR development is attenuated compared to that in mature neonates with normal birth weight.<\/jats:p>","DOI":"10.3389\/fcell.2024.1288212","type":"journal-article","created":{"date-parts":[[2024,2,16]],"date-time":"2024-02-16T04:31:42Z","timestamp":1708057902000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Amelioration of oxygen-induced retinopathy in neonatal mice with fetal growth restriction"],"prefix":"10.3389","volume":"12","author":[{"given":"Ryusuke","family":"Watanabe","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuang","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomohisa","family":"Sakaue","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuhito","family":"Ikegawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaaki","family":"Ohta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Higaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaki","family":"Mogi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariko","family":"Eguchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2024,2,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"261","DOI":"10.1016\/j.clp.2013.02.004","article-title":"Algorithms for the prediction of retinopathy of prematurity based on postnatal weight gain","volume":"40","author":"Binenbaum","year":"2013","journal-title":"Clin.
