Project description:The growth and development of duck skeletal muscle is an important economic trait that is genetically regulated. The internal mechanism underlying the regulation of skeletal muscle growth and development in ducks remains unclear. The purpose of this study was to identify candidate genes related to growth of duck skeletal muscle. RNA-sequencing technology was used to com-pare the transcriptome of duck breast muscles in an F2 population with the high breast muscle rate (HB) and the low breast muscle rate (LB). A total of 14,522 genes were confirmed to be ex-pressed in the breast muscle, and 173 differentially expressed genes (DEGs) were identified be-tween the HB and LB groups. Functional analysis showed that these DEGs were mainly involved in biological processes and pathways of fat metabolism and muscle growth, especially the FABP3 and MYL4 involved in the PPAR signaling pathway and cardiac muscle contraction pathway. These findings deepened our understanding of the molecular mechanisms involved in muscle growth in ducks, and provided a theoretical basis for improving duck production and breeding of ducks.

Project description:DNA methylation is a key epigenetic modification in mammals, have essential and important roles in muscle development. Here, using cattle as a model, we investigate the systematic association between DNA methylation and muscle development. We sample longissimus thoracis tissues from a famous elite native breed of Chinese Qinchuan cattle living within comparable environments under fetal and adult stages. Using methylated DNA immunoprecipitation sequencing (MeDIP-Seq) , we generate and provide a genome-wide landscapes of DNA methylomes for muscle studies. The analysis shows global similarity and difference among fetal and adult stage and identifies the differentially methylated regions. The differentially methylated regions in promoters are highly associated with muscle development via expression repression of both known muscle-related genes and novel genes. This comprehensive map provides a solid basis for exploring epigenetic mechanisms of muscle growth and development. Examination of 2 different developmental stages of the Longissimus Muscle

Project description:Long non-coding RNAs (lncRNAs) have been identified in various tissues and cell types from human, monkey, porcine and mouse. However, expression profile of lncRNAs across Guangxi native cattle and swamp buffalo muscle development has never been investigated. Here, we examine the expression of lncRNA in cattle and buffalo muscle at adult stage(12 months), exhibiting the first report of lncRNA in the Guangxi native cattle and swamp buffalo muscle development of a large animal. 16,236 lncRNA candidates were obtained from buffalo skeletal muscle samples, of which a number of lncRNAs were highly abundant, and 2,161 lncRNAs were differentially expressed between buffalo and cattle. Real-time quantitative PCR (qPCR) analysis confirmed the expression profile of these lncRNAs, including several highly abundant lncRNAs, and a subset of differently expressed lncRNAs according to the high-throughput RNA sequencing (RNA-seq) data. These results indicate that abundant lncRNA is differentially expressed in bovine muscle, indicating important and diverse functions in mammalian muscle development.

Project description:Microarray technologies,which can measure the expression of thousands of genes simultaneously are useful in understanding global gene networks and identifying novel genes and functional gene classes.The adipose depots may have various adipogenic state-specific genes and regulations of adipose accretion patterns in beef cattle.Therefore,the purpose of this study was to examine the molecular mechanisms of longissimus dorsi muscle,subcutaneous and abdominal adipose tissue depots in a native Chinese yellow breed by identifying differentially expressed genes using Bovine Genome Array.The GO and pathway analysis further validated differentially expressed genes identified in array analysis.

Project description:In this project we try to character potential candidate genes and signaling pathways related to PM development during late-term embryonic to neonatal development in indigenous chinese duck breeds. We use RNA-seq to analyse PM samples selected at embryonic days (E) 21 and 27 and 5 days post-hatch (dph) in Gaoyou and Jinding ducks. There were about 45 million clean reads, the total mapped rate was 58.58%–64.82%, and the uniquely mapped rate was 56.21%–63.55%.The results of cluster analysis of DEGs are shown that with the same developmental time nodes superimposed. There were 522 DEGs between Gaoyou and Jinding ducks at E21, including 146 novel genes. There were 299 DEGs and 81 novel genes at E27, and 510 DEGs and 118 novel genes at 5 dph. A total of 43 DEGs were shared by both breeds at all time points, including 19 novel genes.We further considered the 393 genes with expression patterns in line with the muscle development curve in both breeds. these DEGs may be involved in the mechanisms responsible for the phenomenon of static or decreased breast muscle growth in duck breeds during the late embryonic period.

Project description:Muscle development and lipid deposition are complex processes regulated by a coordinated expression profile of genes. Pekin ducks displayed a significant difference from Cherry Valley duck in muscle fiber development and IMF contents. Genetic comparisons between these two breeds would contribute to the exploration of mechanisms underlying the phenotypic differences. In the present study, breast tissues of Pekin (BD) and Cherry Valley (CD) ducks were used for RNA-seq in two different time points (3 and 6-week) to investigate the transcriptome basis. A total of 16705 genes from duck breast muscle were detected as positively expressed genes (RPKM>0.1) and 2273 genes were regarded as novel genes. Differentially expressed genes (DEGs) in BD3 VS CD3 were regarded as muscle development-related genes as CD3 grown faster than BD3 in muscle fibers. DEGs in BD6 VS CD6 were regarded as lipid-related genes as a much higher IMF contents in BD6 than CD6 while no differences observed in 3-week. DEGs obtained from BD3 VS BD6 and CD3 VS CD6 were also analyzed as relative genes here. In all, 9 genes (MAT1A, KAZALD1, SHROOM3, KLHL6, MYH13, ALDOA, TNNT2, PDLIM3 and PFKM) were validated as muscle development correlated candidate genes, and another 11 genes (DHCR24, CNTFR, ANGPTL4, BCL6, HIP1, TRIB1, ADORA1, C1QTNF2, CD36, PRKAG2 and ACSL1) were regarded as lipid correlated genes in duck. What’s more, functional analysis confirmed that the immune reaction, ECM and energy metabolism also correlated with muscle development and lipid deposition closely. The present study not only enlarged the duck genetic information pool but also provided a dozen of candidate genes related to muscle development and lipid deposition, which laid a firm foundation for the further studies on molecular mechanisms in duck.
