Project description:We found that 18-week administration of a prolyl hydroxylase inhibitor, enarodustat, improved glucose/lipid metabolism of BTBR ob/ob mice, which is a model of obesity and type 2 diabetes mellitus. Enarodustat-treated mice also exhibited reduced albuminuria along with ameliorated glomerular epithelial and endothelial damage. In order to elucidate the mechanism of renoprotection, we performed microarray gene expression analysis of isolated glomeruli. The initial screening process revealed 8965 probes whose absolute values of log2 (BTBR ob/ob mice treated with enarodustat/BTBR ob/ob mice treated with vehicle-only) exceeded 0.5. We then compared the expression levels of those 8965 probes between BTBR ob/ob and wild-type mice to identify molecules that were likely to be involved in the pathogenesis of glomerular injury. Such analysis revealed 71 genes which were significantly up-regulated and 47 genes which were significantly down-regulated in BTBR ob/ob mice compared to wild-type mice. The genes were ranked according to their fold-change values, and the analysis presented Ccl2/Mcp1 as the second-most up-regulated gene in BTBR ob/ob mice. The expression level of Ccl2/Mcp1 increased by 24.42-fold in BTBR ob/ob compared to wild-type mice, and its expression in enarodustat-treated BTBR ob/ob mice was decreased to 0.62 of the vehicle-only treated BTBR ob/ob mice. Urinary CCL2/MCP-1 was indeed decreased in enarodustat-treated BTBR ob/ob mice. In vitro experiments also showed that enarodustat suppressed palmitate-induced CCL2/MCP-1 production in murine mesangial cells. Taken together, enarodustat is likely to confer renoprotection through regulating the expression of CCL2/MCP-1 in the glomerulus.

Project description:Obesity is a strong risk factor for the development of type 2 diabetes. We have previously reported that in adipose tissue of obese (ob/ob) mice, the expression of adipogenic genes is decreased. When made genetically obese, the BTBR mouse strain is diabetes susceptible and the C57BL/6J (B6) strain is diabetes resistant. We used DNA microarrays and RT-PCR to compare the gene expression in BTBR-ob/ob versus B6-ob/ob mice in adipose tissue, liver, skeletal muscle, and pancreatic islets. Our results show: 1) there is an increased expression of genes involved in inflammation in adipose tissue of diabetic mice; 2) lipogenic gene expression was lower in adipose tissue of diabetes-susceptible mice, and it continued to decrease with the development of diabetes, compared with diabetes-resistant obese mice; 3) hepatic expression of lipogenic enzymes was increased and the hepatic triglyceride content was greatly elevated in diabetes-resistant obese mice; 4) hepatic expression of gluconeogenic genes was suppressed at the prediabetic stage but not at the onset of diabetes; and 5) genes normally not expressed in skeletal muscle and pancreatic islets were expressed in these tissues in the diabetic mice. We propose that increased hepatic lipogenic capacity protects the B6-ob/ob mice from the development of type 2 diabetes. Diabetes 52:688â700, 2003 Experiment Overall Design: Four B6-ob/ob and four BTBR-ob/ob male mice at 14 weeks of age were used in the microarray study. RNA samples from two individuals were pooled for each tissue, and each pooled RNA sample was applied to an Affymetrix MGU74AV2 array. Because of the scarcity of islets in the BTBR-ob/ob mice, 4 additional mice were pooled to obtain islet RNA from these animals. Sixteen MGU74Av2 arrays (2 strains X 4 tissues X 2 replicates = 16 arrays) were used to monitor the expression level of â12,000 genes or ESTs.

Yandell, and Alan D. Attie*,§ ; Departments of * Biochemistry, and Statistics and Horticulture, University of Wisconsin, Madison, WI, 53706; and Affymetrix, Inc., Santa Clara, CA 95051 ; Communicated by Neal L. First, University of Wisconsin, Madison, WI, July 13, 2000 (received for review April 3, 2000) ; Obesity is strongly correlated with type 2 diabetes mellitus, a common disorder of glucose and lipid metabolism. Although adipocytes are critical in obesity, their role in diabetes has only recently been appreciated. We conducted studies by using DNA microarrays to identify differences in gene expression in adipose tissue from lean, obese, and obese-diabetic mice. The expression level of over 11,000 transcripts was analyzed, and 214 transcripts showed significant differences between lean and obese mice. Surprisingly, the expression of genes normally associated with adipocyte differentiation were down-regulated in obesity. Not all obese individuals will become diabetic; many remain normoglycemic despite profound obesity. Understanding the transition to obesity with concomitant diabetes will provide important clues to the pathogenesis of type 2 diabetes. Therefore, we examined the levels of gene expression in adipose tissue from five groups of obese mice with varying degrees of hyperglycemia, and we identified 88 genes whose expression strongly correlated with diabetes severity. This group included many genes that are known to be involved in signal transduction and energy metabolism as well as genes not previously examined in the context of diabetes. Our data show that a decrease in expression of genes normally involved in adipogenesis is associated with obesity, and we further identify genes important for subsequent development of type 2 diabetes mellitus. Experiment Overall Design: For obesity study, lean samples include C57BL/6J lean, (C57BL/6J X BTBR) F1 and BTBR lean, obese sampples incluse C57BL/6J-ob/ob, (C57BL/6J X BTBR) F2-ob/ob and BTBR-ob/ob. All samples are subjected to Mu11K A and B arrays. Experiment Overall Design: For diabetes study, B6-ob/ob, (C57BL/6J X BTBR) F2-ob/ob low glucose, (C57BL/6J X BTBR) F2-ob/ob medium glucose, (C57BL/6J X BTBR) F2-ob/ob high glucose, and BTBR-ob/ob samples were analyzed for genes whose expression levels changes correlated with the plasma glucose levels in these mice. All samples are subjected to Mu11K A and B arrays.

Project description:The cross-species molecular heterogeneity from mice to patients poses grand challenges for translational research endeavors. A high-fat diet (HFD) model and a genetic model (BTBR ob/ob) at different stand points were used to generate cell atlases of diabetic and obese mise. We identified a previously unrecognized, expanding Trem2-High macrophage population in kidneys of HFD mice that modeled human TREM2-high macrophages in obese patients. Taken together, our cross-species comparison highlights shared immune and metabolic cell-state changes.

Project description:Female mouse models of diabetic peripheral neuropathy (DPN) have not yet been identified. Our aim is firstly to demonstrate that female BTBR ob/ob mice display robust DPN and secondly, to perform relevant comparisons with non-diabetic and gender-matched controls. Lastly, microarray technology was employed to identify dysregulated genes and pathways in the SCN and DRG of female BTBR mice. Dorsal root ganglia (DRG) and sciatic nerve (SCN) were removed from female mice, RNA isolated and processed for gene expression profiling to identify differentially expressed genes using Affymetrix GeneChip Mouse Genome 430 2.0 Arrays.

Project description:Comparison of gene expression in pancreatic islets of BTBR-ob/ob mouse model of obesity-induced type 2 diabetes, and in non-diabetic control mice, B6-ob/ob identified Asf1b as an important gene candidate predictive of diabetic outcome. Asf1B expression was suppressed in response to age in both B6 and BTBR islets, induced by obesity only in B6 islets. This is consistent with other studies reporting a decline in -cell proliferation with age. Asf1b also strongly correlated (R ~ 0.98) with cellular proliferation marker Mki67. Overexpression of Asf1B induced β-cell proliferation in human islets. We show that many genes involved in regulation of cell cycle or programmed cell death are differentially regulated by Asf1B overexpression.
