Project description:Abdominal fat deposition is an important trait in meat-producing ducks. F2 generations of 304 Cherry Valley and Runzhou Crested White ducks were studied to identify genes and lncRNAs affecting abdominal fat deposition. RNA sequencing was used to study abdominal fat tissue of four ducks each with high or low abdominal fat rates. In all, 336 upregulated and 297 downregu-lated mRNAs, and 95 upregulated and 119 downregulated lncRNAs were identified. Target gene prediction of differentially expressed lncRNAs identified 602 genes that were further subjected to Gene Ontology and KEGG pathway analysis. The target genes were enriched in pathways associ-ated with fat synthesis and metabolism and participated in biological processes, including Linoleic acid metabolism, lipid storage, and fat cell differentiation, indicating that these lncRNAs play an important role in abdominal fat deposition. This study lays foundations for exploring molecu-lar mechanisms underlying the regulation of abdominal fat deposition in ducks and provides a theoretical basis for breeding high-quality meat-producing ducks.

Project description:we collected tissues of subcutaneous fat and longissimus dorsi (LD) muscle from individuals that have divergent of backfat thickness and intramuscular fat content, and have similar age and body weight. The transcriptomic and proteomic data were gained using RNA-Seq and TMT to identify the key genes and pathways that specifically regulate the subcutaneous fat and intramuscular fat deposition in Dingyuan pig.

Project description:The liver responsible for 90% lipid synthesis in poultry thus plays important role in the growth of Muscovy duck, which obtains high-fat deposition ability in a time-dependent manner. Therefore, male Muscovy ducks at the age of 14, 28, 42, and 56 days were selected for body weight (BW), carcass weight (CW), subcutaneous fat thickness (SFT), abdominal fat weight (AFW), intramuscular fat content (IMF), breast muscle fiber (BMF) diameter and density determination. Two-dimensional electrophoresis (2-DE) combined with liquid chromatography linked to tandem mass spectrometry (LC-MS/MS) was used to analyze the differentially expressed proteins in the liver at each stage.

Project description:<h4>Background: </h4> The study of fat deposition in yaks of different gender plays a positive role in improving the meat quality and breeding of yaks. In this work, the characteristic of fat deposition in male and female yaks, and the regulations of gender difference to fat deposition in yaks were explored. <h4>Result: </h4> Compared with male yaks, the female yaks possessed higher or more body fat rate (BFR) of visceral except liver, fat content in muscle and liver and subcutaneous fat ( p < 0.05); the cholesterol (CH), triglyceride (TG), very low-density lipoprotein (VLDL), leptin (LEP) and cortisol (COR) in serum of female yaks were higher ( p < 0.05 ); meanwhile, the fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC), stearoyl-CoA desaturase (SCD) and diacylglycerol acyltransferase 1 (DGAT-1) in livers of female yaks were higher ( p < 0.05). The metabonomics analysis showed 13(S)-HODE, linoleic acid and linolenic acid and myo-inositol in subcutaneous fat of female yaks increased ( p < 0.05 ); meanwhile, the transcriptomic analysis the gene expressions of prenylcysteine oxidase 1 (PCYOX1), acyl-coenzyme a-cholesterol acyltransferase (ACAT), protein farnesyltransferase subunit beta (FNTB), apolipoprotein E (ApoE), DGAT2, very long chain fatty acids protein 6 (ELOVL6), NADP-dependent malic enzyme (ME1), SCD, acyl-CoA-binding protein (ACBP) and perilipin-5 (PLIN5), LEP, sterol regulatory element-binding protein 1 (SREBF1) upregulated in subcutaneous fat of female yaks ( p FDR < 0.05), whereas the gene expressions of CPT1, acetyl-CoA acyltransferase 1(ACAA1) and adipose triglyceride lipase (ATGL) downregulated ( p FD R < 0.01). <h4>Conclusion: </h4> The fat and cholesterol synthesis increased in liver of female yaks, and the fat transport in blood of female yaks increased too. In subcutaneous fat of female yaks, the high levels of myo-inositol activated the calcium signaling, following the increase of secretion in fat cell. Then, the high levels of LEP and 13(S)-HODE strengthened PPAR signal, and the fat synthesis, cholesterol synthesis, fatty acid biosynthesis of the linoleic and linolenic acid being the precursor increased, whereas lipolysis and fatty acid oxidation decreased by the regulation of downstream genes in PPAR signal. Meanwhile, SREBF1 also played an important part in the regulation of fat metabolism in yaks of different gender.

Project description:Fat is an important energy store in animals, especially pigs, because of their high fat deposition ability. In animal husbandry, fat content is closely related to animal's lean meat rate and other important economic traits. Long-chain non-coding RNA regulates numerous biological processes, including lipid metabolism. Resveratrol (RES) has been reported to have anti-obesity effects. However, it is unclear whether RES can control fat deposition in pigs by regulating the activities of long-chain non-coding RNAs (lncRNA). The aim of this study was to examine the expression of lncRNA in subcutaneous fat tissues of pigs fed RES-supplemented diet. A total of 12 Duroc × Landrace × Yorkshire hybrid pigs were randomly assigned to two diets, the control diet and the experimental diet containing 400 mg/kg RES. At the end of the study, RNA sequencing was carried out, and the results indicated the expression of lncRNA in the adipose tissues of pigs from the two groups. A total of 499 lncRNAs were identified. Eighty-two (82) differentially expressed genes, including 5 lncRNAs and 77 mRNAs, were also identified. We also observed that the lncRNAs, MSTRG.12490 and MSTRG.13223 targeted the mRNAs, THBS4 and SFPR2, respectively. Results of Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses showed that the differentially expressed genes were mainly involved in adipocytokine signaling pathway, Wnt signaling pathway, PI3K-Akt signaling pathway, and MAPK signaling pathway, which are associated with glycolipid metabolism.Results from this study contributes to the knowledge of the genes and pathways involved in fat metabolism in pigs and the role of RES in the diet of pigs.
