Delayed activation of host innate immune pathways in streptozotocin-induced diabetic hosts leads to more severe disease during infection with Burkholderia pseudomallei

ABSTRACT: The purpose of this study was to develop a comprehensive picture of the STZ-diabetic host transcriptional response during the acute stage of melioidosis and investigate the interplay between the diabetic host response and Burkholderia pseudomallei. To adress this, we compared the transcriptome of infected STZ-diabetic liver and spleen with uninfected STZ-diabetic tissues over an infection period of 42 hr (16 hpi, 24 hpi and 42 hpi, respectively) to identify genes whose expression is altered in response to an acute infection. The microarray experimental design included 3 biological replicates for each time point and both liver and spleen were harvested for RNA extraction. The microarray data from each time point was compared relative to uninfected diabetic mice. In addition, the transcriptome of uninfected STZ-diabetic liver and spleen were also compared with uninfected buffer (sodium citrate) control mice.

Differential Expression of MicroRNAs in Mouse Liver under Aberrant Energy Metabolic Status

Project description:Despite years of effort, exact pathogenesis of non-alcoholic fatty liver disease (NAFLD) remains obscure. To gain an insight into the regulatory roles of microRNAs (miRNAs) in aberrant energy metabolic status and pathogenesis of NAFLD, we analyzed the expression of miRNAs in livers of ob/ob mice, streptozotocin (STZ)-induced type 1 diabetic mice and normal C57BL/6 mice by miRNA microarray. Compared to normal C57BL/6 mice, ob/ob mice showed up-regulation of 8 miRNAs and down-regulation of 4 miRNAs in fatty livers. Up-regulation of miR-34a and down-regulation of miR-122 was found in livers of STZ-induced diabetic mice. These results demonstrate that distinct miRNAs are strongly dysregulated in NAFLD and hyperglycemia. Comparison between miRNA expressions in livers of ob/ob mice and STZ-administered mice further revealed up-regulation of 4 miRNAs and down-regulation of 2 miRNAs in livers of ob/ob mice, indicating that these miRNAs may represent a molecular signature of NAFLD. A distinctive miRNA expression pattern was identified in ob/ob mouse liver and hierarchical clustering of this pattern could clearly discriminate ob/ob mice from either normal C57BL/6 mice or STZ-administered mice. These findings suggest an important role of miRNAs in hepatic energy metabolism and implicate the participation of miRNAs in the pathophysiological processes of NAFLD. Keywords: disease state analysis In the present study, we analyzed the expression of miRNAs in livers of 10 ob/ob mice, 8 streptozotocin (STZ)-induced type 1 diabetic mice and 8 normal control C57BL/6 mice by miRNA microarray.

Hepatic gene expression in streptozotocin-induced diabetic mice fed a quercetin diet

Project description:Quercetin is a food component that may ameliorate the diabetic symptoms. We examined hepatic gene expression of BALB/c mice with streptozotocin (STZ)-induced diabetes to elucidate the mechanism of the protective effect of dietary quercetin on diabetes-associated liver injury. We fed STZ-induced diabetic mice with diets containing 0.1% or 0.5% quercetin for 2 weeks and compared the patterns of hepatic gene expression in these groups of mice using a DNA microarray. Diets containing 0.1% or 0.5% quercetin lowered the STZ-induced increase in blood glucose levels and improved plasma insulin levels. A cluster analysis of the hepatic gene expressions showed that 0.5% quercetin diet suppressed STZ-induced alteration of gene expression. Gene set enrichment analysis (GSEA) and quantitative RT-PCR analysis showed that the quercetin diets had their greatest suppressive effect on the STZ-induced elevation of expression of cyclin dependent kinase inhibitor p21(WAF1/Cip1) (Cdkn1a). Six-week-old male mice were divided into 4 groups of 6 mice each, housed in groups of 3 per cage. After 1 week mice were intraperitoneally injected with STZ. Mice (n=6) in the untreated control group did not receive any treatment. After 1 week, 18 mice showing non-fasting blood glucose levels of 230-400 mg/dL were divided into 3 groups: one group was fed with AIN93G only (control group), the others with an AIN93G diet containing 0.1% or 0.5% quercetin (Funakoshi, Tokyo, Japan) for 2 weeks.
