Specific mesoderm subset derived from human pluripotent stem cells ameliorates microvascular pathology in type 2 diabetic mice

ABSTRACT: Human iPSCs were differentiated into a specific mesoderm subset characterized by KDR+CD56+APLNR+ (KNA+) expression. KNA+ cells possessed high clonal proliferative potential and specification into endothelial colony forming cell (ECFC) phenotype. KNA+ cells differentiated into perfused blood vessels when implanted subcutaneously into the flank of NOD/SCID mice and when injected into the vitreous of type 2 diabetic mice (db/db mice). Transcriptomic analysis showed that differentiation of hiPSCs derived from diabetics into KNA+ cells was sufficient to change baseline differences in gene expression caused by the diabetic status and reprogram diabetic cells to a pattern similar to KNA+ cells derived from nondiabetic hiPSCs. Proteomic array studies performed on retinas of db/db mice injected with either control or diabetic donor derived KNA+ cells showed correction of aberrant signaling in db/db retinas towards normal healthy retina. These data provide “proof of principle” that KNA+ cells restore perfusion and correct vascular dysfunction in db/db mice.

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.

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.

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.

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.
