Transcription profiling of congenic rat strains

ABSTRACT: Expression analysis was carried out in Goto-Kakizaki (GK), Brown Norway (BN) and 24 derived congenic strains using the Illumina RatRef-12 microarray. Each congenic line contains an introgression of a single fragment of the GK strain in the background of the BN recipient strain or vice versa. The resulting lines were fixed by imbreeding. The sizes of the introgressed fragments vary from almost a complete chromosome (consomic) to smaller fragments and some of the fragments overlap. To investigate genetic control of gene expression by the introgressed fragments, we performed transcriptional profiling of liver, soleus muscle and white adipose tissue in 6 months old rats.

Post-translational protein modifications such as acetylation have significant regulatory roles in metabolic processes, but their relationship to both variation in gene expression and DNA sequence is unclear. We address this question in the Goto-Kakizaki (GK) rat inbred strain, a model of polygenic type 2 diabetes. Expression of the NAD-dependent deacetylase Sirtuin-3 is down-regulated in GK rats compared to normoglycemic Brown Norway (BN) rats. We show first that a promoter SNP causes down-regul ...[more]

MiRNA expression in adipose tissue and liver from a spontaneous rat model of Type 2 diabetes

Project description:MicroRNAs (miRNAs) are non-coding RNA molecules involved in post-transcriptional control of gene expression of a wide number of genes, including those involved in glucose homeostasis. Type 2 diabetes (T2D) is characterized by hyperglycaemia and defects in insulin secretion and action at target tissues. Using a miRNA microarray platform, we sought to establish differences in miRNA expression in two insulin-target tissues (liver and adipose tissue) from seven-month-old spontaneously diabetic (Goto-Kakizaki [GK]) and non-diabetic (Brown-Norway [BN]) rats. MiRNA data were integrated with gene expression data from the same rats to investigate how differentially expressed miRNAs affected the expression of their predicted target genes. Two-colour experiment comparing GK and BN rat strains for two different tissues. Biological replicates: 4 GK and 4 BN rats; adipose tissue and liver extracted from each rat. Two samples were hybridised to each array (one of each strain, same tissue)

Genetic and genomic analysis of hyperlipidemia, obesity and diabetes using TALLYHO x C57BL6 F2 mice

Project description:Type 2 diabetes (T2D) is the most common form of diabetes in humans and is closely associated with dyslipidemia and obesity that magnifies the mortality and morbidity related to T2D. The TALLYHO/JngJ (TH) mouse is a polygenic model for T2D characterized by obesity, hyperinsulinemia, impaired glucose uptake and tolerance, hyperlipidemia, and hyperglycemia. To determine the genetic factors that contribute to these T2D related characteristics in TH mice, we interbred TH mice with C57BL/6J (B6) mice. The parental, F1, and F2 mice were phenotyped at 8, 12, 16, 20, and 24 weeks of age for 4-hour fasting plasma triglyceride, cholesterol, insulin, and glucose levels, as well as body weights. Fat pad and carcass weights were measured at 24 weeks after sacrificing the mice. The F2 mice were genotyped genome-wide for 68 markers. Of 393 genotyped F2 mice, 16 were chosen from the extremes of the triglyceride distribution (8 high and 8 low), and liver, pancreas, muscle and adipose tissue were measured for gene expression. Gene expression quantitative trait locus (eQTL) analysis aided in selection of candidates underlying hyperlipidemia, diabetes and obesity QTLs. We identified several genetic loci that affected quantitative variation in plasma lipid and glucose levels and obesity traits. 16 (8 high and 8 low) out of 393 F2 mice were chosen from the extremes of the triglyceride distribution, excluding overtly diabetic mice, and liver, pancreas, muscle and adipose tissue were measured for gene expression. In addition to data from the 64 microarrays on the 16 mice, a supplemental file with phenotypes and marker genotypes is provided for all mice as a supplementary file on the Series record (below). Mouse identification numbers are included to connect the data files.

Project description:Type 2 diabetes (T2D) is characterized by hyperglycaemia and defects in insulin secretion and action at target tissues. Using the Illumina RatRef-12 v1.0 array, gene expression was assessed in two insulin-target tissues (liver and adipose tissue) from seven-month-old spontaneously diabetic (Goto-Kakizaki [GK]) and non-diabetic (Brown-Norway [BN]) rats.

RNA-seq analysis of Entamoeba histolytica glycerol 3-phosphate dehydrogenase (G3PDH) and glycerol kinase (EhGK) gene silencing strain

Project description:Amebiasis is caused by the protozoan parasite Entamoeba histolytica. Treatment options other than metronidazole and its derivatives are few, and their low efficacy against asymptomatic cyst carriers, and experimental evidence of resistance in vitro justify the discovery/repurposing campaign for new drugs against amebiasis. To better understand the role of glycerol metabolism in this parasite, we focused on characterizing two important enzymes, glycerol kinase (GK) and glycerol 3-phosphate dehydrogenase (G3PDH). Recombinant GK was biochemically characterized in detail, while G3PDH was not due to failure of protein expression and purification. GK revealed novel characteristics and unprecedented kinetic properties in reverse reaction. Gene silencing revealed that GK is essential for optimum growth, whereas G3PDH is not. Gene silencing of G3PDH caused upregulated GK expression, while that of GK resulted in upregulation of antioxidant enzymes as shown by RNA-seq analysis. Although the precise molecular link between GK and the upregulation of antioxidant enzymes was not demonstrated, the observed increase in antioxidant enzyme expression upon GK gene silencing suggests a potential connection between GK and the cellular response to oxidative stress. Together, these results provide the first direct evidence of the biological importance and coordinated regulation of the glycerol metabolic pathways for proliferation and antioxidative defense in E. histolytica, justifying the exploitation of these enzymes as future drug targets.

Array CGH between GK and Wistar Rats for Detecting Copy Number Variations

Project description:The Goto-Kakizak (GK) rat, a nonobese animal model of Type 2 diabetes (T2D), were developed by repeated inbreeding of glucose-intolerent individuals selected from Wistar rats. During their development, GK rats suffer from reduced beta-cell mass and insulin resistance spontaneously (T2D phenotype), which are supposed to be caused by loci holding different genotypes between GK and Wistar rats. This array CGH experiment can detect loci which show different copy numbers (genotype) between GK and Wistar rats. These loci serve as a valuable repository for mining candidates contributing to the pathogenesis of T2D.
