Microarray Analysis on the Differences of Gene Expression in Longissimus Dorsi Muscle Tissue between 1-month and 24-month Chinese Red Steppes

ABSTRACT: In order to establish the correlation between biological processes and the mechanisms of gene expression controlling beef traits formation in bovine, microarray analysis was performed to capture the differences in gene expression related to beef traits profile in Longissimus Dorsi muscle tissue between 1-month and 24-month Chinese Red Steppes. 1282 (5.6%) probes showed significant differences at the two stages in the experiment, and 1008 differential gene annotations were obtained using Capitalbio molecule annotation system. BLAST analysis revealed that 1001(78.1%) probe genes shared significant similarity in amino acid sequence with other functional genes (As of June 2009). 126 genes showing strong correlation with beef traits were gained by the GO analysis. With the KEGG analysis, 63 pathways were found to be related to beef traits which involved 73 genes. 28 genes were found in a single pathway, while 35 genes were found in 2-16 pathways respectively. The panels of transcripts and gene pathways analysis in different growth stages may be helpful for the study on beef traits formation, and the gene expression profile construction in Longissimus Dorsi muscle tissues, would make a foundation for screening candidate genes which have genetic effect on meat quality in bovine.

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.

Transcription profiling of Bos taurus Longissimus dorsi skeletal muscle from Korean Native Cattle (Hanwoo)

Project description:To identify transcriptional markers for beef traits related to meat tenderness and moisture, we measured the transcriptome of the Longissimus dorsi skeletal muscle in 10 Korean native cattle (KNC). We analyzed the correlation between the beef transcriptome and measurements of four different beef traits, shear force (SF), water holding capacity (WHC), cooking loss (CL), and loin eye area (LEA). We obtained non-overlapping and unique panels of genes showing strong correlations (|r| > 0.8) with SF, WHC, CL, and LEA, respectively. Functional studies of these genes indicated that SF was mainly related to energy metabolism, and LEA to rRNA processing. Interestingly, our data suggested that WHC is influenced by protein metabolism. Overall, the skeletal muscle transcriptome pointed to the importance of energy and protein metabolism in determining meat quality after the aging process. The panels of transcripts for beef traits may be useful for predicting meat tenderness and moisture. Experiment Overall Design: Gene expression profiles were correlated with beef traits measured at the same cattle.

Small RNA sequencing Analysis of adipose in six month calf Chinese swamp buffalo

Project description:Background: Intramuscular fat (IMF) content is an important index for beef quality. However, the genetics of IMF deposition is complex and still largely unclear, especially in buffalo. To identify miRNAs with potential regulatory role in lipid accumulated in muscle, we performed small RNA sequencing and identified miRNAs expressed in the longissimus dorsi muscle and back fat of Chinese buffalo, which provided vital information for further identification of miRNAs with potential regulatory role in the lipid accumulated in muscle. Results: Three small RNA libraries were constructed. A total of 32762032 raw reads were obtained from adipose groups, respectively. After filtering the adaptor and low quality reads, 32054381 clean reads were retained. In total, 623 miRNAs were identified.

Comparison of transcriptome profiles between bulls and steers in the longissimus dorsi muscle of Korean cattle

Project description:Purpose: The goals of this study are to determine effects of castration on gene expression in longissimus dorsi muscle by comparing transcriptome profiles and to search candidate genes related with beef quality like flavor, tenderness, juiciness and fat deposition Methods: longissimus dorsi muscle mRNA profiles of 3 bulls and 3 steers of Korean cattles were generated by RNA sequencing using Illumina NextSeq 500. After quality checking, Tophat2 software was used for read mapping, and EdgeR was used to identify differentially expressed genes (DEGs) between bulls and steers. Gene ontology pathway analysis on DEGs was conducted with DAVID tool for categorization of DEGs. Results: Using an optimized data analysis workflow, we mapped about 58 million sequence reads per sample to the bovine genome (build UMD3.1) and identified 18,027 expressed genes in the longissimus dorsi muscle of bulls and steers with TopHat2 workflow. RNA-seq data confirmed 1,146 differentially expressed genes (adjusted p-value, FDR <0.05). Conclusions: We comparatively analyzed the transcriptome profile from longissimus dorsi muscle of bulls and steers of Korean cattles using NGS and identified DEGs between bulls and steers. The functional annotation analysis of DEGs found that transcriptome profile difference in longissimus dorsi muscle by castration.

Early postmortem gene expression and its relationship to composition and quality traits in pig Longissimus dorsi muscle

Project description:A mRNA expression study has been performed 20-25 minutes postmortem obtained samples from Longissimus dorsi muscle of 59 Duroc x LD/LW pigs to search for gene sequences related to meat quality (pH24, pH45, “Lab” colour coordinates, curing yield and exudation at three different times) or to meat composition (intramuscular fat, content of several fatty acid (C16:0, C18:0, C18:1 and C18:2), ratio of saturated, monounsaturated and polyunsaturated fatty acids, and protein and humidity contents) traits in order to find targets for selection. Gene ontology analysis, biological pathways and gene networks studies all show, that many more differentially expressed genes (506 vs 279) are related to meat quality (Group P, or perimortem characters) than to meat composition traits (Group L, or whole life traits). The difference between the number of GO terms annotated, biological pathways and gene networks in groups P and L is notable due to the differences in the complexity of the “generation process” of P-traits and the involvement of other tissues or organs in the generation of variability of L-traits. Also, interactions between a list of differentially expressed genes were found in ECM-receptor interaction, TGF-beta signaling pathway, fatty acid elongation in mitochondria and adipocytokine signalling pathway indicating that a substantial fraction of the gene networks could be associated with interactions between differential expressed genes related to traits under study. A high number of the most overexpressed genes are related to muscle development and functionality and repair mechanisms; they could be good candidates for breeding programs whose main goal is to enhance meat quality. 59 Longissimus Dorsi samples from 59 LD/LW x Duroc cross. A total of 33 traits on composition, conformation and meat quality and compositional traits were recorded in the left Longissimus dorsi muscle.
