Candidate SNPs for carcass and meat traits in Nelore animals and in their crosses with Bos taurus Repositório Alice
CURI, R. A.; KRAUSKOPF, M. K.; HADLICH, J. C.; FORTES, M. R. S.; VANKAN, D. M.; SILVA, J. A. V.; OLIVEIRA, H. N. de; MOTA, M. D. S. da.
The objective of this work was to evaluate the effects of single?nucleotide polymorphisms (SNPs) in the genes IGF1 (AF_017143.1:g.198C>T), MSTN (AF_320998.1:g.433C>A), MYOD1 (NC_007313:g.1274A>G) and MYF5 (NC_007303:g.1911A>G) on carcass and meat traits in Nelore (Bos indicus) and Nelore x B. taurus. A total of 300 animals were genotyped and phenotyped for rib eye area (REA), backfat thickness (BT), intramuscular fat (IF), shear force (SF) and myofibrillar fragmentation index (MFI). The effects of allele substitution for each SNP were estimated by regression of the evaluated phenotypes on the number of copies of a particular allele using the general linear model. The polymorphism at IGF1 was non?informative in Nelore animals. In crossbred...

Genetic polymorphisms related to meat traits in purebred and crossbred Nelore cattle. Repositório Alice
CURI, R. A.; FORTES, M. R. S.; CHARDULO, L. A. L.; SILVEIRA, A. C.; DE BENI ARRIGONE, M.; MARTINS, C. L.; ASSUMPÇÃO, M. E. O. d' A.; OLIVEIRA, H. N. de.
Abstract - The objective of this work was to estimate the allelic and genotypic frequencies of CAST/XmnI, a calpastatin gene polymorphism, and CAPN530, a calpain 1 large subunit gene polymorphism, in different beef genetic groups (Nelore and Nelore x Bos taurus), and to investigate associations between these polymorphisms and carcass and meat traits. Three hundred animals ? comprising 114 Nelore, 67 Angus x Nelore, 44 Rubia Gallega x Nelore, 41 Canchim, 19 Brangus three-way cross and 15 Braunvieh three-way cross ? were genotyped by PCR-RFLP and phenotyped for rib-eye area (REA), back-fat thickness (BT), intramuscular fat (IF), shear force (SF) and myofibrillar fragmentation index (MFI). The occurrence of the two alleles of the CAST/XmnI and CAPN530 single...

Genetic regulators of mineral amount in Nelore cattle muscle predicted by a new co-expression and regulatory impact factor approach. Repositório Alice
AFONSO, J.; FORTES, M. R. S.; REVERTER, A.; DINIZ, W. J. da S.; CESAR, A. S. M.; LIMA, A. O. de; PETRINI, J.; SOUZA, M. de S.; COUTINHO, L. L.; MOURÃO, G. B.; ZERLOTINI NETO, A.; GROMBONI, C. F.; NOGUEIRA, A. R. A.; REGITANO, L. C. de A..
Mineral contents in bovine muscle can affect meat quality, growth, health, and reproductive traits. To better understand the genetic basis of this phenotype in Nelore (Bos indicus) cattle, we analysed genome-wide mRNA and miRNA expression data from 114 muscle samples. The analysis implemented a new application for two complementary algorithms: the partial correlation and information theory (PCIT) and the regulatory impact factor (RIF), in which we included the estimated genomic breeding values (GEBVs) for the phenotypes additionally to the expression levels, originally proposed for these methods. We used PCIT to determine putative regulatory relationships based on significant associations between gene expression and GEBVs for each mineral amount. Then, RIF...

Muscle transcriptome analysis reveals genes and metabolic pathways related to mineral concentration in Bos indicus. Repositório Alice
AFONSO, J.; COUTINHO, L. L.; TIZIOTO, P. C.; DINIZ, W. J. da S.; LIMA, A. O. de; ROCHA, M. I. P.; BUSS, C, E.; ANDRADE, B. G. N. A.; PIAYA. O.; SILVA, J. V.; LINS, L. A.; GROMBONI, C. F.; NOGUEIRA, A. R. de A.; FORTES, M. R. S.; MOURÃO, G. B.; REGITANO, L. C. de A..
Mineral content affects the biological processes underlying beef quality. Muscle mineral concentration depends not only on intake-outtake balance and muscle type, but also on age, environment, breed, and genetic factors.

The Bos taurus-Bos indicus balance in fertility and milk related genes. Repositório Alice
KASARAPU, P.; PORTO NETO, L. R.; FORTES, M. R. S.; LEHNERT, S. A.; MUDADU, M. de A.; COUTINHO, L. L.; REGITANO, L. C. de A.; GEORGE, A.; REVERTER, A..
Numerical approaches to high-density single nucleotide polymorphism (SNP) data are often employed independently to address individual questions. We linked independent approaches in a bioinformatics pipeline for further insight. The pipeline driven by heterozygosity and Hardy-Weinberg equilibrium (HWE) analyses was applied to characterize Bos taurus and Bos indicus ancestry. We infer a gene co-heterozygosity network that regulates bovine fertility, from data on 18,363 cattle with genotypes for 729,068 SNP. Hierarchical clustering separated populations according to Bos taurus and Bos indicus ancestry. The weights of the first principal component were subjected to Normal mixture modelling allowing the estimation of a gene?s contribution to the Bos taurus-Bos...
