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

ABSTRACT: 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.

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.

Testosterone deficiency induces changes of the transcriptomes of visceral adipose tissue in miniature pigs fed a high-fat and high-cholesterol diet

Project description:Testosterone deficiency causes fat deposit, particularly in the visceral region, and its replacement might reverse fat accumulation, but the underlying mechanisms of such processes are largely unclear. To gain insights into the genome-wide role of testosterone on visceral adipose tissue (VAT), RNA-Seq was used to investigate testosterone deficiency induced changes of VAT in miniature pigs fed a high-fat and high-cholesterol (HFC) diet among intact male pigs (IM), castrated male pigs (CM), and castrated male pigs with testosterone replacement (CMT) treatments. The results showed that testosterone deficiency induced VAT deposit and increased serum leptin level. Moreover, a total of 1,732 differentially expressed genes (DEGs) were identified between different two groups. Compared with gene expression profiles in IM and CMT pigs, upregulated genes in CM pigs, i.e., LOC100520753 (CD68), LCN2, EMR1, NCF1 (p47phox), and NOX2 (GP91-PHOX), were mainly enriched in inflammatory response, oxidation-reduction process, and response to oxidative stress, while downregulated genes in CM pigs, i.e., DIO3, PCK1, and ABHD5, mainly focused on small molecule metabolic process. Taken together, our study provides a novel genome-wide view on the role of testosterone on VAT deposit under HFC diet, thus improving our understanding of the molecular mechanisms involved in VAT changes induced by testosterone deficiency.

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.

Evaluation of the impact of the dietary inclusion of salty and sugary former food products on the liver and plasma profile of pigs through OMICS approaches

Project description:The research on alternative and sustainable feed ingredients is a challenge to reduce feed-food competition between humans and monogastrics, in particular pigs. Former food products (FFPs) drop out from the industrial production of food such as pasta, bread, snacks, and chips. They have a high nutritional and energetic value and represent an alternative and sustainable feed ingredient. The aim of this study was to apply omics tools to assess the impact of the dietary inclusion of FFPs in pigs’ diet. For the in vivo trial, thirty-six Swiss Large White male castrated pigs were randomly assigned to three dietary groups: control (CTR), 30% replacement of CTR diet with salty FFPs (SA), 30% replacement of CTR diet with sugary FFPs (SU). The trial lasted from the start of the growing phase (22.4 ± 1.7 kg) until slaughtering phase (110 ± 3 kg). After slaughtering, blood and liver tissue samples were collected and processed according to the omics approaches used. The number of differentially regulated proteins in each comparison matrix (SA/SU vs. CTR) indicated a marginal impact on liver function, as measured by proteomics on tissue samples. The peptidomics investigation on plasma samples showed low variability between the peptidome of the three dietary groups and identified three possible bioactive peptides associated with anti-hypertension in the SA dietary group. To conclude, the safety and the limited impact of the SA and SU diets on liver proteome and plasma peptidome strengthened the idea of recycling FFPs as feed ingredients to make pig production more sustainable.

A pilot proteomic study reveals different protein profiles related to testosterone and gonadotropin changes in a short-term controlled healthy human cohort

Project description:Testosterone deficiency afflicts approximately 30% of men aged from 40-89 years. It is associated with type 2 diabetes, metabolic syndrome and cardiovascular disease. However, the causality of the relationship between low testosterone and metabolic diseases is unclear. We have analysed plasma samples from thirty healthy male volunteers (19-32 years of age) with pharmacologically-induced testosterone deficiency. Blood samples were collected under three conditions: normal testosterone (baseline), ‘zero’ testosterone and ‘restored’ testosterone. As a proof-of-concept, a sample pooling approach was used to obtain one pool per condition, with each pool consisting of 30 individual samples. The proteomic profiles identified significant functional differences, related to the innate immune system, the regulation of insuline-like growth factors, collagen degradation, glycolysis/gluconeogenesis process, among others.
