Project description: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.

Keywords: Microarray analysis; Beef traits; Differences of gene expression; Longissimus Dorsi muscle tissue; Chinese Red Steppe A total of 18 bulls of the same breed (Chinese Red Steppe) were included in the study; 9 were 1month old while another 9 were 24 months old and were provided by Jilin Academy of Agricultural Sciences. They were maintained in standard conditions and fed with standard diet. The bulls were humanely killed at the slaughter house of the academy, and fresh longissimus dorsi muscle tissues were obtained during slaughter, immediately frozen in liquid nitrogen and stored at -80M-BM-0C for microarray analysis.

Project description:Bovine longissimus lumborum (LL) and psoas major (PM) muscles biopsy samples were collected from four carcasses (n = 4) at 45 min, 12 h, and 36 h postmortem from a commercial beef processing facility. Proteome profile variation between beef LL and PM during the early postmortem period were evaluated by tandem mass tag labeling containing ten different isobaric compounds.

Project description:MicroRNAs (miRNAs) are small (∼22 nucleotides) noncoding ribonucleic acids (RNAs) that regulate gene expression by binding to their complementary sequences. Recent years, a great deal of miRNAs which highly-enriched in skeletal muscle have been identified, which can influence multiple facets of muscle development and function through their regulation of key genes controlling myogenesis. However, to date no miRNAs have been reported to modulate muscle development in goat. Total RNAs from the xuhuai goats longissimus thoracis at fetal and six month old stages were used to construct small RNA libraries for Solexa SBS technology sequencing. In the small RNA profile, a total of 15,627,457 clean reads were obtained from the fetal goat library and 15,593,721 clean reads from the six month old goat library. There are 471 conserved miRNAs overlapped in both libraries, of which 343 miRNAs were differential expressed. We identified 122 novel miRNAs in the fetal caprine library and 53 novel miRNAs in the six month old-caprine library.

Project description:The transcriptome of bovine Longissimus thoracis muscles from 15- and 19-month-old Charolais young bulls were analyzed in order to identify genes whose expression level was associated to beef quality scores, in particular to tenderness, juiciness and flavor, and to muscle growth potential. The expression of over 5000 genes was compared between high and low meat quality samples according to the three sensory traits, taken individually, and between animals with either a high or a low muscle growth potential. Keywords: meat sensory quality, growth potential

Project description:Texel and Ujumqin sheep show obvious differences in muscle and fat growth, so they are ideal models not only to understand the molecular mechanism in prenatal skeletal muscle development, but to identify the potential target genes of myostatin. To elucidate the phenotypic variation between the two sheep breeds and the dynamic characteristics of gene expression in skeletal muscle during the development, we examined the development of skeletal muscle in transcriptome-wide level at 70, 85,100,120 , 135 days post coitus (dpc),birth, 1 month and 2 month. Using the specialized and standardized sheep transcriptome-wide oligo DNA microarray (Agilent), we analyzed the transcriptomic profiles of longissmuss dorsi muscle from fetuses of Texel and Ujumqin sheep. We characterized dynamic transcriptome-wide profiles that accompany the prenatal skeletal muscle and fat development in Texel and Ujumqin sheep respectively, and compared the difference in profiles of gene expression between the two sheep breeds at the same developmental stage.Some potential myostatin target genes and other genes controlling the growth of skeletal muscle and adipose were identified for further examinations. Our findings not only contribute to understand the molecular mechanism of prenatal skeletal muscle development in large precocial species, but also provide some clues for human myopathy and obesity at prenatal stages. Moreover, we also can identify putative candidate genes for meat quality traits in farm animals. Longissimus dorsi muscles were sampled from five prenatal development stages (70, 85, 100, 120 and 135 day of gestation) in Texel and eight development stages (at 70, 85, 100, 120, 135 days post coitus (dpc), birth, 1 month and 2 month) in Ujumqin sheep. There were at least three replicates at each development time in each breed. Two gene expression experiments were conducted with a total of 40 hybridizations.

Project description:It has been proved that intramuscular fat (IMF) or marbling in beef improves palatability. Recently, consumers have considered not only the degree of marbling but also the size and distribution of marbling flecks for their health and appetizing looking of beef. Computer image analysis (CIA) systems have been developed to assess various characteristics of marbling particles (MPs) such as the number, size, and distribution (fineness or coarseness) objectively. Some CIA indexes about MPs indicating how MPs are distributed evenly had significant positive relationship with price which represents consumers’ interest. RNA-seq research about formation of fine MPs in the longissimus thoracis (LT) muscle tissue of cattle have not yet been tried in transcriptome level. This study was conducted to reveal the DEGs between groups which have high or low number of fine MPs in the Longissimus thoracis muscle of Korean beef cattle and to understand molecular events associated with marbling fineness.
