“…Once the ribeye area is considered a polygenic trait and is highly influenced by several environmental factors, many genes and mechanisms that induce differences in the growth of the Nellore breed are still unknown. Despite the crossing between the taurine and zebu breeds leads to higher carcass yields and ribeye area, as the proportion of zebu genes increases (Mendonça et al, 2021) , our results suggest that the expression levels of IGF-1 and IGF-2 genes do not exert a direct effect on REA in Nellore animals of this study and other genes D r a f t are related with the highest ribeye area (Vignato et al, 2017, Silva et al, 2020. No significant differences were found in the expression of NEDD4 (E3 ubiquitin protein ligase) and UBE4A (Ubiquitin conjugation factor E4) genes between the two groups (Table 4).…”

Despite several studies on genetic markers and differently expressed genes related to ribeye area (REA) and tenderness traits in beef cattle, there is divergence in the results regarding the genes associated with these traits. Thirteen genes that had been associated or have biological functions that may influence such phenotypes were included in this study. A total of five genes for REA (IGF-1, IGF-2, MSTN, NEDD4, and UBE4A) and eight genes for meat tenderness (CAPN1, CAPN2, CAST, HSPB1, DNAJA1, FABP4, SCD, and PRKAG3) were selected from previously studies in beef cattle. Genes and its respective proteins expression were validated in a commercial population of Nellore cattle using quantitative real-time PCR (RT-qPCR) and advanced mass spectrometry (LC / MS-MS) techniques, respectively. MSTN gene was upregulated in animals with low REA. CAPN1, CAPN2, CAST, HSPB1, and DNAJA1 genes were upregulated in animals with tougher meat. The proteins translated by these genes were not differentially expressed. Our results could confirm the potential of some studied genes as biomarkers for carcass and meat quality in Nellore cattle.
