Project description:Although the well-known importance of pig in agriculture, as well as a model for human biology, the miRNA catalog of pig has been largely undefined. Identification and preliminary characterization of adipose- and muscle-specific miRNAs would be a prerequisite for a thorough understanding of their roles in regulating adipose deposition and muscle growth. In the present study, we get insight into the miRNA transcriptome in eight adipose tissues, two skeletal muscles and cardiac muscle of pig using deep sequencing technology, and to elucidate their characteristic tissue-specific profiles and genomic context. Eleven small RNA libraries from eight adipose tissues, two skeletal muscle tissues and cardiac muscle of pig were sequenced.

Project description:It is evident that epigenetic factors, especially DNA methylation, play essential roles in obesity development. To learn systematic association of DNA methylation to obesity, we used pig as a model, and sampled eight diverse adipose tissues and two distinct skeletal muscle tissues from three pig breeds with distinguished fat levels: the lean Landrace, the fatty Rongchang, and the feral Tibetan pig. We sequenced 180 methylated DNA immunoprecipitation (MeDIP) libraries, generated 1,381 Gbp sequence data, and provided a genome-wide DNA methylation map for pig adipose and muscle studies. The analysis showed global similarities and differences between breeds, genders and tissues, and identified the differentially methylated regions (DMRs) that are preferentially located in intermediate CpG promoters and CpG island shores. The DMRs in promoters are highly associated to obesity development. We also analyzed methylation and regulation of the known obesity-related genes and predicted novel candidate genes. The comprehensive map here provides a solid base for exploring epigenetic mechanisms of adipose deposition and muscle growth. We collected eight diverse adipose tissues and two phenotypically distinct skeletal muscle tissues from three well-defined pig models with distinct fat rates, and studied genome-wide DNA methylation differences among breeds, males and females, and tissues.

Project description:Obese and lean-type pig breeds show obvious differences in adipose deposition and muscle growth; however, the molecular mechanisms underlying this phenotypic variation remains unclear. Landrace (a leaner, Western breed), Rongchang (a fatty, Chinese breed) and Tibetan (a feral, indigenous Chinese breed that has not undergone artificial selection) pig breeds were used in this study. We collected eight diverse adipose tissues and two phenotypically distinct skeletal muscle tissues from three well-defined pig models with distinct fat rates, and studied mRNA expression differences among breeds, males and females, and tissues. These results highlight some possible candidate genes for porcine adipose deposition and muscle growth and provide some data on which to base further studies of the molecular basis of energy metabolism. The mRNA expression differences of eight diverse adipose tissues and two phenotypically distinct skeletal muscle tissues from three well-defined pig models with distinct fat rates are measured.

Project description:Domestication of pig results in modifications of many traits, including fatness traits, which are important in pig production since they have effect on meat quality, fattening efficiency, reproduction and immunity.In this study, we investigate 3D genome organization and transcriptomic characterization of adipose tissues (ATs) between wild boars and Bama pig, a typical indigenous domestic pig in China, to uncover molecular mechanisms of fatness-phenotypic shifts.

Project description:Background Clenbuterol, a beta-agonist, can dramatically reduce pig adipose accumulation at high dosages. However, it has been banned in pig production because people who eat pig products treated with clenbuterol can be poisoned by the clenbuterol residues. To understand the molecular mechanism for this fat reduction, cDNA microarray, real-time PCR, two-dimensional electrophoresis and mass spectra were used to study the differential gene expression profiles of pig adipose tissues treated with/without clenbuterol. The objective of this research is to identify novel genes and physiological pathways that potentially facilitate clenbuterol induced reduction of adipose accumulation. Results Clenbuterol was found to improve the lean meat percentage about 10 percent (P< 0.5). The adipose cells became smaller and the muscle fibers became thicker with the administration of clenbuterol. The mRNA abundance of 82 genes (ESTs) were found to be statistically differentially expressed based on the Student t-test (P<0.5) in the microarray analyses which containing 3358 genes (ESTs).Theses 82 genes (ESTs) were divided into four groups according to their Gene Ontology Biological Process descriptions. 16 genes were cellular metabolism related genes (including five lipids metabolism related such as apolipoprotein D and apolipoprotein R), 10 were signal transduction related genes, 45 were expressed sequence tags (ESTs) and other 11 others were of various categories. Eleven of the 82 genes (ESTs) were chosen for real-time PCR analysis, with eight of them induced to express similar magnitudes as in the microarray analyses, two could not be detected and one expressed magnitudes that disagreed with the microarray results. Apolipoprotein R was also found to be up-regulated by the proteomic analysis. Conclusions Profound changes were observed in adipose cells after administration of clenbuterol in pigs by histological section and cDNA microarray techniques. The adipose cells became smaller with stimulation by clenbuterol. Changes in mRNA abundance indicated that DNA transcription and protein translation were enhanced in the adipose cells with clenbuterol stimulation. Five lipids metabolism related genes, such as apoD and apoR, were significantly up-regulated. ApoR was up-regulated in both the mRNA transcription and the protein synthesis. ApoR may be one of the critical molecules through which clenbuterol reduces fat accumulation. Keywords: dose response
