Gene expression data of the subcutaneous adipose tissue from entire male, immunocastrated and surgically castrated pigs

Project description:Differences in adipose tissue deposition and properties between pig male sex categories, i.e., entire male, immunocastrated and surgically castrated pigs are relatively well characterized, whereas the underlying genetic mechanisms are still not fully understood. To gain the knowledge about the genetic regulation of the differences in adipose tissue deposition, RNA-sequencing approach was used. A total of 83 differentially expressed genes were identified between entire male and immunocastrated pigs, 15 between immunocastrated and surgically castrated pigs and 48 between entire male and surgically castrated pigs by RNA-sequencing of the subcutaneous adipose tissue. Comparing entire male with immunocastrated or surgically castrated pigs, upregulated genes related to extracellular matrix dynamics, and downregulated genes involved in the control of lipid and carbohydrate metabolism were determinated. Moreover, differential gene expression in general indicated a high similarity between immunocastrated and surgically castrated pigs in contrast to entire males, except for several heat shock protein genes which were upregulated in entire male and immunocastrated pigs compared with surgically castrated pigs.

Adipose Tissue Gene Expression of Entire Male, Immunocastrated and Surgically Castrated Pigs.

Project description:Differences in adipose tissue deposition and properties between pig male sex categories, i.e., entire males (EM), immunocastrates (IC) and surgical castrates (SC) are relatively well-characterized, whereas the underlying molecular mechanisms are still not fully understood. To gain knowledge about the genetic regulation of the differences in adipose tissue deposition, two different approaches were used: RNA-sequencing and candidate gene expression by quantitative PCR. A total of 83 differentially expressed genes were identified between EM and IC, 15 between IC and SC and 48 between EM and SC by RNA-sequencing of the subcutaneous adipose tissue. Comparing EM with IC or SC, upregulated genes related to extracellular matrix dynamics and adipogenesis, and downregulated genes involved in the control of lipid and carbohydrate metabolism were detected. Differential gene expression generally indicated high similarity between IC and SC as opposed to EM, except for several heat shock protein genes that were upregulated in EM and IC compared with SC. The candidate gene expression approach showed that genes involved in lipogenesis were downregulated in EM compared with IC pigs, further confirming RNA-sequencing results.

Hepatic transcriptome changes in testosterone-deficient pigs fed a high-fat diet

Project description:To gain insight into the role of testosterone in modulating hepatic fat accumulation, we collected liver tissues from high fat diet-fed intact male pigs, castrated male pigs, and castrated male pigs with testosterone replacement. RNA-Seq was employed to profile hepatic gene expression in pigs with different testosterone levels. Liver mRNA profiles of intact male pigs fed a HFC diet, castrated male pigs fed a HFC diet, and castrated male pigs treated with testosterone fed a HFC diet were generated by deep sequencing, using Illumina HiSeq 2000.

Renal transcriptome changes in testosterone deficient-pigs fed a high-fat diet

Project description:Purpose: Obesity and dyslipidemia are associated with increased risk of renal disease.Testosterone deficiency aggravated high-fat diet-induced obesity and hypercholeterolemia. However,whether testosterone deficiency or testosterone deficiency-induced dyslipidemia aggravate the progression of renal disease is not clear. To gain insight into the role of testosterone in modulating renal lipid metabolism, we profiled renal gene expression by RNA-Seq in HFC-fed intact male pigs (IM), castrated male pigs (CM), and castrated male pigs with testosterone replacement (CMT). Methods: Sexually mature male miniature pigs were either surgical castrated or sham-operated, and castrated with testosterone replacement. We administrated to pigs a high-fat and high-cholesterol (HFC) diet for twelve weeks. RNA-Seq was employed to profile renal gene expression in pigs with different testosterone levels. Conclusions: This study demonstrated that testosterone deficiency aggravated renal lipid accumulation in pigs fed an HFC diet and that these effects could be reversed by testosterone replacement therapy. Impaired metabolic processes, bile acid secretion,estrogen signaling pathway and enhanced triglyceride synthesis may contribute to the increased renal lipid accumulation induced by testosterone deficiency and an HFC diet.

Differential expression and co-expression gene networks reveal candidate biomarkers of boar taint in non-castrated pigs (RNA-seq data set)

Project description:Boar taint (BT) is an offensive odour or taste observed in pork from a proportion of non-castrated male pigs. Surgical castration is effective in avoiding BT, but animal welfare issues have created an incentive for alternatives such as genomic selection. In order to find candidate biomarkers, gene expression profiles were analysed from tissues of non-castrated pigs grouped by their genetic merit of BT. Differential expression analysis revealed substantial changes with log-transformed fold changes of liver and testis from −3.39 to 2.96 and −7.51 to 3.53, respectively. Co-expression network analysis revealed one module with a correlation of −0.27 in liver and three modules with correlations of 0.31, −0.44 and −0.49 in testis. Differential expression and co-expression analysis revealed candidate biomarkers with varying biological functions: phase I (COQ3, COX6C, CYP2J2, CYP2B6, ACOX2) and phase II metabolism (GSTO1, GSR, FMO3) of skatole and androstenone in liver to steroidgenesis (HSD17B7, HSD17B8, CYP27A1), regulation of steroidgenesis (STARD10, CYB5R3) and GnRH signalling (MAPK3, MAP2K2, MAP3K2) in testis. Overrepresented pathways included “Ribosome”, “Protein export” and “Oxidative phosphorylation” in liver and “Steroid hormone biosynthesis” and “Gap junction” in testis. Future work should evaluate the biomarkers in large populations to ensure their usefulness in genomic selection programs.

Soybean molasses increases subcutaneous fat deposition while reducing lipid oxidation in the meat of castrated lambs

Project description:This study aimed to evaluate the effect of including soybean molasses (SM) on performance, blood parameters, carcass traits, meat quality, fatty acid and muscle (longissimus thoracis) transcriptomic profiles of castrated lambs. Twenty Dorper × Santa Inês lambs (20.06 ± 0.76 kg BW) were assigned to a randomized block design, stratified by BW, with the following treatments: CON - 0 g/kg of SM and SM20 - 200 g/kg of SM on DM basis, allocated in individual pens. The diet consisted of 840 g/kg concentrate and 160 g/kg corn silage for 76 days, with the first 12 days as an adaptation period and the remaining 64 days on the finishing diet. The SM20 diet increased blood urea concentration (P = 0.03) while reduced glucose concentration (P = 0.04). Lambs fed SM showed higher subcutaneous fat deposition (P = 0.04) and higher subcutaneous adipocyte diameter (P < 0.01), in addition to reduced meat lipid oxidation (P < 0.01). Soybean molasses reduced the quantity of branched-chain fatty acids in longissimus thoracis (P = 0.05) and increased the quantity of saturated fatty acids (P = 0.01). In the transcriptomic analysis, 294 genes were identified as differentially expressed, which belong to pathways such as oxidative phosphorylation, citric acid cycle, and monosaccharide metabolic process. In conclusion, diet with SM increased carcass fat deposition, reduced lipid oxidation, and changed the energy metabolism, supporting its use in ruminant nutrition.

Transcriptome analysis of mRNAs, lncRNAs, and circRNAs during the differentiation of porcine subcutaneous preadipocytes

Project description:Subcutaneous preadipocyte differentiation play a critical role in fat deposition of pigs. However, the action of different RNAs in subcutaneous preadipocyte differentiation, such as messenger RNAs (mRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), are still largely unclear. In the present study, a transcriptome analysis including mRNAs, lncRNAs, and circRNAs was performed in different stages of D0, D2, D4, and D8 using RNA-seq technology. Our results identified 1,554, 470, 1,344, 1,777, and 676 differentially expressed (DE) mRNAs, 112, 58, 95, 136, and 93 DE lncRNAs, and 902, 787, 710, 932, and 850 DE circRNAs between D2 and D0, between D4 and D2, between D8 and D4, between D4 and D0, and between D8 and D0, respectively. Moreover, functional enrichment analysis showed that the common DE mRNAs during entire differentiation were mainly involved in lipid metabolic and cell differentiation processes. Additionally, co-expression network analysis identified the potential lncRNAs related to adipogenesis, e.g., MSTRG.42239 and MSTRG.146410. Taken together, this study provides a genome-wide landscape of RNA expression profiles during subcutaneous preadipocyte differentiation, thus improving our understanding of molecular mechanism in regulating subcutaneous adipogenesis of pigs.
