Project description:This study was performed to determine the effects of dietary fat sources, i.e., beef tallow, soybean oil, olive oil and coconut oil (each 3% in feed), on the growth performance, meat quality and gene expression in growing-finishing pigs. The results of this study indicate that the type of dietary fat affects fatty acid composition and insulin signaling-related gene expression in the longissimus dorsi muscle of pigs. Effects of dietary fat types on meat quantity, meat quality and gene expression in pig.

Project description:Intramuscular fat (IMF) content is an important trait closely correlated with meat quality, which is highly variable among swine breeds from diverse genetic backgrounds. In order to elucidate the molecular mechanism underlying porcine meat quality, we adopted RNA-sequencing to detect transcriptome in the longissimus dorsi muscle of Wei pigs (a Chinese indigenous breed) and Yorkshire pigs (a Western lean-type breed) with different IMF content. A total of 717 differentially expressed genes (DEGs) were identified in our study, with 323 up-regulated and 394 down-regulated genes in Wei pigs compared with Yorkshire pigs. GO analysis showed that DEGs significantly related to muscle proliferation and development, lipid storage and catabolic, extracellular matrix structural constituent, and neutral amino acid transmembrane transporter activity. Pathway analysis revealed that DEGs associated with fatty acid metabolism, steroid biosynthesis, glycerophospholipid metabolism, protein digestion and absorption, and amino acid metabolism. Quantitative real time PCR confirmed the differential expression of 11 selected DEGs from both pig breeds. The results provide useful information to investigate the transcriptional profiling in skeletal muscle of different pig breeds with divergent phenotypes, and several DEGs can be taken as functional candidate genes for affecting pork quality.

Project description:Meat quality is one of the most important traits in pig production. Long non-coding RNAs (lncRNAs) has been involved in diverse biological processes such as muscle development through regulating gene expression. However, studies on lncRNAs lag behind and a comparatively small number of lncRNAs have been identified in pigs. Also, effects of lncRNAs on meat quality remains to be characterized. Here, we analyzed lncRNAs in longissimus thoracis (LT) and semitendinosus (ST) muscles, being different in meat quality, with RNA-sequencing technology. A total of 500 differentially expressed lncRNAs (DELs) and 2094 protein-coding genes (DEGs) were identified. Through KEGG analysis on DELs we first made clear that fat deposition might be the main reason resulting in differential phenotype of LT and ST, on the basis of which 41 key DELs and 50 DEGs involved in differential fat deposition were characterized. One of the key genes, cAMP-response element binding protein 1, was selected to confirm its role in porcine adipogenesis with molecular biology methods and found that it promotes the differentiation of porcine preadipocytes, consistent with its higher expression level and intramuscular fat contents in LT than that in ST muscle. Furthermore, through integrated analysis of DELs and DEGs, transcription factors important for differential fat deposition were characterized among which BCL6 have the most target DEGs while MEF2A was targeted by the most DELs. The results provide candidate genes crucial for meat quality, which will contribute to revealing the molecular mechanisms underlying meat quality

Project description:Porcine latissimus dorsi muscle is one of the main sources of pork products. Meat quality indicators such as the proportion of muscle fibres within the latissimus dorsi muscle and intramuscular fat deposition change during the growth and development of pigs.We used single-nucleus sequencing (snRNA-seq) to analyse the changes occurring in the longest dorsal muscles of pigs at different growth stages
