Isolated myoblasts were incubated in 22 different culture media, designed using a {3, 5} simplex lattice design to cover the entire range of compositions for each BCAA. The proliferation was estimated based on cell quantities after 72 h of incubation. The proliferation data under different BCAA combinations were fitted using Scheffé's seven-term special cubic model for three components. The response surfaces of proliferation showed a convex configuration, with increases in Ile leading to a decrease in proliferation. The maximal proliferation was observed at Leu and Val proportions of 3:7 and 1:1 in an Ile-free medium, as measured by the DNA assay and water-soluble tetrazolium salt (WST-8) assay, respectively. These findings suggest that Val has a greater influence than Leu on myoblast proliferation, particularly in DNA content. The responses of myoblast proliferation-associated factors, Pax7 and p21, corresponded to the proliferation evaluated with DNA and WST-8 assays, respectively. These results indicate that the growth of chick myoblast cells is affected by the combination of BCAAs in a three-component system.</p>\u0000 </div>","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cells treated with varying PUFA ratios showed a significant reduction in cell viability, which was alleviated by the ferroptosis inhibitor ferrostatin-1 (fer-1). The 20:1 n-6 PUFA ratio exhibited the most pronounced decrease in cell viability and the greatest increase in malondialdehyde (MDA) levels, a marker of lipid peroxidation. Levels of 4-hydroxynonenal (4-HNE), total iron, and proinflammatory cytokine IL-6 were significantly elevated in the 5:1, 10:1, and 20:1 groups, with fer-1 treatment mitigating these effects. The GSSG/GSH ratio, an indicator of oxidative stress, also significantly increased in the 10:1 and 20:1 groups.
