Inositol requiring enzyme 1α augments angiogenesis for diabetic wound healing

ABSTRACT: The microarray analysis is to investigate the different expression profile of microRNAs in bone marrow-derived progenitor cells from type 2 diabetic mice and healthy control mice. microRNA expression profiles were compared between bone marrow-derived progenitor cells from either type 2 diabetic db/db mice or their in-colony control litter db/+ mice.

Inositol requiring enzyme 1? augments angiogenesis for diabetic wound healing

Project description:The microarray analysis is to investigate the different expression profile of microRNAs in bone marrow-derived progenitor cells from type 2 diabetic mice and healthy control mice. microRNA expression profiles were compared between bone marrow-derived progenitor cells from either type 2 diabetic db/db mice or their in-colony control litter db/+ mice. Total RNA was extracted from bone marrow-derived progenitor cells from either type 2 diabetic db/db mice (Jackson lab, # 000642) or their in-colony control litter db/+ mice. N=3 per group.

RNA-seq analysis of diabetes induced changes in macrophage transcriptome

Project description:Macrophage dysfunction and polarization plays key role in chronic inflammation associated with diabetes and its complications. However, the effect of diabetes on macrophage transcriptome including long non-coding RNAs is not known. Here, we analyzed global changes in transcriptome of bone marrow macrophages isolated from type 2 diabetic db/db mice and control littermates db/+ mice using high throughput RNA-seq technique. Data analysis showed that expression of genes relevant to fibrosis, cell adhesion and inflammation were altered in diabetic db/db mice relative to control db/+ mice. Furthermore, expression of several known and novel long non coding RNAs and nearby genes was altered in db/db mice. Gene ontology and IPA showed activation of signaling netwroks relevant to fibrosis, cell adhesion and inflammatory pathways . This study for the first time demonstrated that diabetes profoundly affects macrophage transcriptome including expression of long non coding RNAs and altered the levels of genes relevant to diabetes complications. Bone marrow macrophages were isolated from 12 weeks old type 2 diabetic male db/db mice and control littermates db/+ mice. These were differentiated in culture for 7-8 days in the presence of 10 ng/ml of MCSF-1 (BMMC) or 20 ng/ml of GM-CSF (BMGM). Then RNA was extracted and used for RNA-seq.

Expression analysis in pancreatic and liver tissues of diabetic db/db mice in response to dietary supplementation with selenate

Project description:Investigation of gene expression level changes in pancreatic and liver tissues of diabetic db/db mice supplemented with selenate, compared to the diabetic db/db mice administered placebo. Fasting blood glucose levels increased continuously in diabetic db/db mice administered placebo (DMCtrl) but decreased gradually in selenate-supplemented diabetic db/db mice (DMSe) and approached normal values when the experiment ended. The size of pancreatic islets increased, causing the plasma insulin concentration to double in DMSe mice compared with that in DMCtrl mice. Two six chip studies using total RNA respectively isolated from pancreatic and liver tissues of three selenate-supplemented diabetic db/db mice, and three diabetic db/db mice administered placebo.

Transcriptome Alteration in the Diabetic Heart by Rosiglitazone: Implications for Cardiovascular Mortality

Project description:The type 2 diabetes medication, rosiglitazone, has come under scrutiny for possibly increasing the risk of cardiac disease and death. To investigate the effects of rosiglitazone on the diabetic heart, we performed cardiac transcriptional profiling of a murine model of type 2 diabetes, the C57BL/KLS-leprdb/leprdb (db/db) mouse. We compared cardiac gene expression profiles from three groups: untreated db/db mice (db-c), db/db mice after rosiglitazone treatment (db-t), and non-diabetic db/+ mice. Mice were divided into three groups: Non-diabetic controls (db/+), untreated diabetic controls (db-c), and rosiglitazone-treated diabetic mice (db-t). Whole-heart RNA from five mice from each of the three groups after four months with or without treatment was used for microarray analysis.Universal Reference RNAs for mouse (Stratagene, La Jolla, CA) were purchased as microarray reference controls.

Integrative transcriptomic profiling of a mouse model of hypertension-accelerated diabetic kidney disease

Project description:Aim: To compare transcriptomic profiles of kidney cortex between healthy db/m mice, and mice with early stage diabetic kidney disease (uninephrectomized db/db injected with LacZAAV) and advanced stage diabetic kidney disease (uninephrectomized db/db mice injected with ReninAAV) Methods: Bulk RNA sequecing using the Illumina NextSeq 500 platform. Results: We identified 5,500 differentially expressed genes (DEGs) in db/db UNx LacZAVV mice compared to healthy controls, and 4,470 DEGs were identified in db/db UNx ReninAAV mice compared to healthy controls. Also, we showed in supplementery files that 3,039 DEGs were identified between db/db UNx LacZAAV mice and db/db UNx ReninAAV mice. Conclusion: We identified several gene expression changes in our two animal models of diabetic kidney disease.

Expression data from whole retina of 8-week old db/db diabetic mice and lean littermates

Project description:Diabetic retinopathy is one of the leading causes of blindness in diabetic patients. Emerging evidence suggests that retinal neurodegeneration is an early event in the pathogenesis of diabetic retinopathy, but the underlying causes of neuronal loss are unknown. To unravel potential mechanisms underlying early retinal neurodegeneration in diabetic retinopathy, a gene expression profiling study was undertaken to compare the gene expression in retinas of 8-week db/db diabetic mice with that of lean non-diabetic littermates. Retinas were obtained from 8-week db/db diabetic mice and age-matched lean non-diabetic controls. Total RNA was extracted and processed for being hybridized onto affymetrix DNA microarrays.
