Transcriptomics analysis of Colon tumor xenograft model in streptozotocin-induced diabetic mice

Project description:This is a transcriptomics analysis contributing to a bigger project that tries to shed light on the role of type 2 diabetes mellitus (T2DM) as a risk factor for colon cancer (CC). Here we present a gene expression screening of 7 colon tumor xenograft samples, 2 with diabetic mice and 5 with normal blood glucose levels. For xenograft model details see: Prieto I, et al. (2017) Colon cancer modulation by a diabetic environment: A single institutional experience. PLoS One 12(3):e0172300

Enarodustat, hypoxia-inducible factor stabilizer, counteracts the diabetic renal energy metabolism alterations in streptozotocin-induced diabetic rats

Project description:We analyzed the effects of enarodustat (JTZ-951; HIF stabilizer) on renal energy metabolism in streptozotocin-induced diabetic rat model. Transcriptome analysis of renal cortex revealed that genes related to fatty acid metabolism and amino acid metabolism were upregulated in diabetes and downregulated by enarodustat, whereas genes related to glucose metabolism were upregulated by enarodustat. Thus, HIF stabilization counteracts the renal energy metabolism alterations occurring in the early stages of diabetic kidney disease.

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

Project description:Phloridzin is a dihydrochalcone typically contained in apples. A diet containing 0.5 % phloridzin significantly improves hyperglycemia but not hypoinsulinemia and tissue lipid peroxidation in streptozotocin (STZ)-induced diabetic mice after 14 days. The phloridzin diet has no effect on the alteration of hepatic gene expression in STZ-induced diabetic mice. A quantitative RT-PCR analysis showed a reversal of the STZ induction of the sodium/glucose cotransporter gene Sglt1 and the drug-metabolizing enzyme genes Cyp2b10 and Ephx1 in the small intestine of mice fed a 0.5% phloridzin diet. These mice also showed a reversal of the STZ-mediated renal induction of the glucose-regulated facilitated glucose transporter gene Glut2. Dietary phloridzin improved the abnormal elevations in blood glucose level and the overexpression of Sglt1, Cyp2b10 and Ephx1 in the small intestine of STZ-induced diabetic mice.

Analysis of altered miRNA expression profiles in the streptozotocin-induced diabetic rats compared to normal SD rats

Project description:Diabetes mellitus (DM) is one of the most common chronic diseases around the world, and diabetic peripheral neuropathy (DPN) is one of the most common complications of DM. We used microarrays to identify the differentially expressed miRNAs in dorsal root ganglia (DRG) tissues from streptozotocin (STZ)-induced diabetic rats, taking normal SD rats as controls, and tried to find out the related genes which may be involved in the development of DPN.

Comparison of Glomerular and Podocyte mRNA Profiles in eNOS-/- Diabetic Mice Induced by Streptozotocin

Project description:We compared mRNA profiles of isolated glomeruli versus sorted podocytes between diabetic and control mice. IRG mice crossed with eNOS-/- mice were further bred with podocin-rTTA and TetON-Cre mice to permanently label podocytes before the diabetic injury. Diabetes was induced by injection of streptozotocin. mRNA profiles of isolated glomeruli and sorted podocytes from diabetic and control mice at 10 weeks after induction of diabetes were examined. Consistent with the previous reports, expression of podocyte-specific markers in the glomeruli were down-regulated in the diabetic mice compared to controls. However, these differences disappeared when mRNA levels were corrected for podocyte number per glomerulus. Interestingly, the expression of these markers was not altered in sorted podocytes from diabetic mice, suggesting that the reduced expression of podocyte markers in isolated glomeruli is likely a secondary effect of reduced podocyte number, rather than the loss of differentiation markers. Analysis of the differentially expressed genes in diabetic mice also revealed distinct up-regulated pathways in the glomeruli (mitochondrial function and oxidative stress) and podocytes (actin organization). In conclusion, our data suggest that podocyte-specific gene expression in transcriptome obtained from the whole glomeruli may not represent those of podocytes in the diabetic kidney. We compared mRNA profiles of isolated glomeruli versus sorted podocytes between diabetic and control mice.
