Co-expression networks reveal potential regulatory roles of miRNAs in fatty acid composition of nelore cattle. Repositório Alice
OLIVEIRA, P. S. N. de; COUTINHO, L. L.; CESAR, A. S. M.; DINIZ, W. J. da S.; SOUZA, M. de S.; ANDRADE, B. G.; KOLTES, J. E.; MOURÃO, G. B.; ZERLOTINI NETO, A.; REECY, J. M.; REGITANO, L. C. de A..
Fatty acid (FA) content affects the sensorial and nutritional value of meat and plays a significant role in biological processes such as adipogenesis and immune response. It is well known that, in beef, the main FAs associated with these biological processes are oleic acid (C18:1 cis9, OA) and conjugated linoleic acid (CLA-c9t11), which may have beneficial effects on metabolic diseases such as type 2 diabetes and obesity. Here, we performed differential expression and co-expression analyses, weighted gene co-expression network analysis (WGCNA) and partial correlation with information theory (PCIT), to uncover the complex interactions between miRNAs and mRNAs expressed in skeletal muscle associated with FA content. miRNA and mRNA expression data were...

SOUZA, M. M. de; NICIURA, S. C. M.; ROCHA, M. I. P.; PAN, Z.; ZHOU, H.; BRUSCADIN, J. J.; DINIZ, W. J. da S.; AFONSO, J.; OLIVEIRA, P. S. N. de; MOURÃO, G. B.; ZERLOTINI NETO, A.; COUTINHO, L. L.; KOLTES, J. E.; REGITANO, L. C. de A..
Abstract. Background:Beef tenderness is a complex trait of economic importance for the beef industry. Understanding the epigenetic mechanisms underlying this trait may help improve the accuracy of breeding programs. However, little is known about epigenetic effects on Bos taurus muscle and their implications in tenderness, and no studies have been conducted in Bos indicus.Results:Comparing methylation profile of Bos indicus skeletal muscle with contrasting beef tenderness at 14 days after slaughter, we identified differentially methylated cytosines and regions associated with this trait. Interestingly, muscle that became tender beef had higher levels of hypermethylation compared to the tough group. Enrichment analysis of predicted target genes suggested...

Gene co-expression analysis indicates potential pathways and regulators of beef tenderness in Nellore cattle. Repositório Alice
GONÇALVES, T. M.; REGITANO, L. C. de A.; KOLTES, J. E.; CESAR, A. S. M.; ANDRADE, S. C. da S.; MOURAO, G. B.; GASPARIN, G.; MOREIRA, G. C. M.; FRITZ-WATERS, E.; REECY, J. M.; COUTINHO, L. L..
Beef tenderness, a complex trait affected by many factors, is economically important to beef quality, industry, and consumer?s palatability. In this study, RNA-Seq was used in network analysis to better understand the biological processes that lead to differences in beef tenderness. Skeletal muscle transcriptional profiles from 24 Nellore steers, selected by extreme estimated breeding values (EBVs) for shear force after 14 days of aging, were analyzed and 22 differentially expressed transcripts were identified. Among these were genes encoding ribosomal proteins, glutathione transporter ATP-binding cassette, sub-family C (CFTR/MRP), member 4 (ABCC4), and synaptotagmin IV (SYT4). Complementary co-expression analyses using Partial Correlation with Information...

Identification of putative regulatory regions and transcription factors associated with intramuscular fat content traits. Repositório Alice
CESAR, A. S. M.; REGITANO, L. C. de A.; REECY, J. M.; POLETI, M. D.; OLIVEIRA, P. S. N.; OLIVEIRA, G. B. de; MOREIRA, G. C. M.; MUDADU, M. de A.; TIZIOTO, P. L.; KOLTES, J. E.; Fritz-Waters, E.; KRAMER, L.; GARRICK, D.; BEIKI, H.; GEISTLINGER, L.; MOURÃO, G. B.; ZERLOTINI NETO, A.; COUTINHO, L. L..
Background: Integration of high throughput DNA genotyping and RNA-sequencing data allows for the identification of genomic regions that control gene expression, known as expression quantitative trait loci (eQTL), on a whole genome scale. Intramuscular fat (IMF) content and carcass composition play important roles in metabolic and physiological processes in mammals because they influence insulin sensitivity and consequently prevalence of metabolic diseases such as obesity and type 2 diabetes. However, limited information is available on the genetic variants and mechanisms associated with IMF deposition in mammals. Thus, our hypothesis was that eQTL analyses could identify putative regulatory regions and transcription factors (TFs) associated with...

Potential biomarkers for feed efficiency-related traits in nelore cattle identified by co-expression network and integrative genomics analyses. Repositório Alice
LIMA, A. O. de; KOLTES, J. E.; DINIZ, W. J. S.; OLIVEIRA, P. S. N. de; CESAR, A. S. M.; TIZIOTO, P. L.; AFONSO, J.; SOUZA, M. de S.; PETRINI, J.; ROCHA, M. I. P.; CARDOSO, T. F.; ZERLOTINI NETO, A.; COUTINHO, L. L.; MOURÃO, G. B.; REGITANO, L. C. de A..
Feed efficiency helps to reduce environmental impacts from livestock production, improving beef cattle profitability. We identified potential biomarkers (hub genes) for feed efficiency, by applying co-expression analysis in Longissimus thoracis RNA-Seq data from 180 Nelore steers. Six co-expression modules were associated with six feed efficiency-related traits (p-value ≤ 0.05). Within these modules, 391 hub genes were enriched for pathways as protein synthesis, muscle growth, and immune response. Trait-associated transcription factors (TFs) ELF1, ELK3, ETS1, FLI1, and TCF4, were identified with binding sites in at least one hub gene. Gene expression of CCDC80, FBLN5, SERPINF1, and OGN was associated with multiple feed efficiency-related traits...

Background: The impact of extreme changes in weather patterns on the economy and human welfare is one of the biggest challenges our civilization faces. From anthropogenic contributions to climate change, reducing the impact of farming activities is a priority since it is responsible for up to 18% of global greenhouse gas emissions. To this end, we tested whether ruminal and stool microbiome components could be used as biomarkers for methane emission and feed efficiency in bovine by studying 52 Brazilian Nelore bulls belonging to two feed intervention treatment groups, that is, conventional and by-product-based diets. Results: We identified a total of 5,693 amplicon sequence variants (ASVs) in the Nelore bulls? microbiomes. A Differential abundance analysis...

The structure of microbial populations in Nelore GIT reveals inter-dependency of methanogens in feces and rumen. Repositório Alice
ANDRADE, B. G. N.; DONATONI, F. A. B.; CUADRAT, R. R. C.; TIZIOTO, P. C.; OLIVEIRA, P. S. N. de; MOURÃO, G. B.; COUTINHO, L. L.; REECY, J. M.; KOLTES, J. E.; WALSH, P.; BERNDT, A.; PALHARES, J. C. P.; REGITANO, L. C. de A..
The success of different species of ruminants in the colonization of a diverse range of environments is due to their ability to digest and absorb nutrients from cellulose, a complex polysaccharide found in leaves and grass. Ruminants rely on a complex and diverse microbial community, or microbiota, in a unique compartment known as the rumen to break down this polysaccharide. Changes in microbial populations of the rumen can affect the host?s development, health, and productivity. However, accessing the rumen is stressful for the animal. Therefore, the development and use of alternative sampling methods are needed if this technique is to be routinely used in cattle breeding. To this end, we tested if the fecal microbiome could be used as a proxy for the...
