Project description:Objective: To investigate the effects of myeloid MR deletion on hepatic gene expression profiles in female mice Methods: 12-week old female FC-ob and MRKO-ob mice were euthanized and livers were collected and snap-frozen with liquid nitrogen. Total RNA were extracted using Trizol. After assessing the RNA quality with an Agilent 2000 Bioanalyzer, cDNA library was constructed using TruSeq RNA-Seq Sample Prep Kits. Deep sequencing was carried out on Illumina HiSeq 2000. Different gene expressions were confirmed by QRT-PCR. Results: With RNA-seq data, we identified 24 genes that differently expressed in MRKO-ob mice compared to FC-ob group. Confirmation with QRT-PCR revealed that the differently expressed genes were closely associated with hepatic steatosis, especially de novo lipogenesis. Conclusions: Our study investigated for the first time the gene expression profiles of female ob/ob mice with or without myeloid MR ablation. These findings provided clues to explore the mechanisms underlied the crosstalk between macrophages and hepatocytes in females. These findings have provided new knowledge basis for potential new strategies to treat or prevent NAFLD and T2DM.

Project description:Analysis of gene expression profiles is an attractive method for discovering how animals respond to environmental challenges in nature. Compared to low altitudes, high altitudes are characterized by reduced partial pressures of oxygen (hypoxia) and cooler ambient temperatures To better understand how mammals cope with high altitudes, we trapped wild house mice (Mus musculus domesticus) from 3 populations in La Paz, Bolivia (3000 - 3600 m) and 3 populations in Lima, Peru (0 – 200 m). Affymetrix GeneChip® Mouse Genome 430 2.0 Arrays were use to measure mRNA abundance in the livers of these mice.

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.

Affymetrix GeneChipM-BM-. Mouse Genome 430 2.0 Arrays were use to measure mRNA abundance in the livers of these mice. Eighteen male house mice were trapped from three different locations (3 mice per location)at high alttiude (La Paz, Bolivia, 3600 m) and from three locations at low altiditude (Lima, Peru, 100 m). Total mRNA was extracted from the livers and used for hybridization of Affymetrix GeneChip Mouse expression set 420.
