RNA-Seq results of four Chinese cattle from longissimus muscles based on Illumina HiSeq 2000 platform

Project description:Purpose: The goals of this study are to identify the molecular mechanism by which NA improves meat quality and find differentially expressed genes in longissimus muscles between cattle treated with/without dietary NA. Methods: gene expression profiles of longissimus muscle from 4 cattle mRNA pools including 6 control and 6 NA treated cattle were generated by single-end sequencing (50 bp), using Illumina HiSeq™ 2000. The sequence reads that passed quality control were analyzed at the transcript isoform level with TopHat followed by Cufflinks. Results: Using SOAPaligner (V2.21) analysis, we mapped about 23,359,272-25,165,811 clean reads per sample to the bovine reference genome assembly (unmasked genomic DNA sequences: Bos_taurus.UMD3.1.75.dna.chromosome.1-29 and X) (ftp://ftp.ensembl.org/pub/release-75/fasta/bos_taurus/dna/). Our NOISeq analysis identified a list of 124 differentially expressed genes with a probability value ≥ 0.8 and an absolute value of log2 Ratio of NA to Control ≥ 1. Conclusions: In our study, dietary NA increases the IMF content of longissimus muscle may through up-regulating the expressions of genes and pathways related to lipid metabolism.

Whole Genome Bisulfite Sequencing of Longissimus Dorsi Muscles between Japanese Black (Wagyu) and Chinese Red Steppes Cattle

Project description:We performed a comparative genome-wide methylation analysis of longissimus dorsi muscles between the Japanese Black (Wagyu) and Chinese Red Steppes cattle, which exhibit significant differences in meat quality traits. This will allow us to better understand the correlation between DNA methylation variants and meat quality traits.

Transcriptome profiling of the intramuscular fat content in Longissimus dorsi between Angus and Chinese Simmental cattle

Project description:The intramuscular fat (IMF) content of different beef cattle breeds varies greatly, which plays an important role in taste and nutritional value. However, the molecular mechanism of fat metabolism and deposition in beef cattle is still not very clear. In this study, the meat quality traits of Angus cattle and Chinese Simmental cattle were compared, the transcriptome of the longissimus dorsi muscle (LD) between Angus cattle and Chinese Simmental cattle was then analyzed to identify key genes related to fat metabolism and adipogenesis by high-throughput RNA-seq technology. In the current study conducted a comprehensive analysis on the transcriptome of the longissimus dorsi muscle (LD) of Angus and Simmental cattle, and identified differentially expressed genes related to lipid metabolism，which may have a great impact on on the formation of IMF.

Transcriptome profiling and Co-expression networks of longissimus dorsi muscle in Gayal（Bos frontalis）and Banna cattle（Bos taurus） with different beef qualities

Project description:The Gayal (Bos frontalis) is a rare semi-domesticated cattle in China. Gayal has typical beef body shape and good meat production performance. Compared with other cattle species, it has the characteristics of tender meat and extremely low fat content. To explore the underlying mechanism responsible for the differences of meat quality between different breeds, the longissimus dorsi muscle (LM) from Gayal and Banna cattle (Bos taurus) were investigated using transcriptome analysis. The gene expression profiling identified 638 differentially expressed genes (DEGs) between LM muscles from Gayal and Banna cattle. Gene Ontology (GO) enrichment of biological functions and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that the gene products were mainly involved in the PPAR signaling pathway, lipid metabolism and amino acid metabolism pathway. Protein-protein interaction（PPI） network analysis showed APOB, CYP7A1, THBS2, ITGAV, IGFBP1 and IGF2R may have great impact on meat quality characteristics of Gayal. Moreover, three transcription factors, FOXA2, NEUROG2, and RUNX1, which may affect meat quality by regulating the expression of genes related to muscle growth and development have also been found. In summary, our research reveals the molecular mechanisms that cause Gayal meat quality characteristics. It will contribute to improving meat quality of cattle through molecular breeding.
