چکیده انگلیسی
In the present study, 155 Nellore cattle were genotyped for the CAPN4751 and UOGCAST polymorphisms and phenotyped for shear force (SF) at 1, 7 and 14 days aging. The effects of different genotypic combinations were evaluated on the Longissimus muscle proteomic profile using 2DE and mass spectrometry. A significant association was found between genotypes for UOGCAST and CAPN4751 and meat tenderness. The CC genotype for both markers was favorable for lesser shear force than TT. A total of 40 spots showed significant differential expression profiles (P < 0.05), of which eight had a main effect for the CAPN4751 marker, 11 for UOGCAST, two for both markers, and 19 had interactions between markers, including myosin (MYL1, MYL2, MYLPF and MYL6B), actin (ACTA1 and CAPZβ), troponin (TNNT1 and TNNT3) and heat shock proteins (HSPB6, HSPB1 and HSP70-2). The results demonstrated that UOGCAST and CAPN4751 genotypes led to variability on the expression of proteins that are involved in muscle metabolism, and consequently affect meat tenderness.
