Project description:Genetics of Kidneys in Diabetes (GoKinD) study is an initiative aimed at identifying susceptibility genes for diabetic nephropathy in type 1 diabetes.
A large number of individuals with type 1 diabetes were screened to identify two subsets, one with clear-cut
kidney disease and another with normal renal status despite long-term diabetes. Those who met additional entry criteria
and consented to participate were enrolled. When possible, both parents were also enrolled to form family trios. Altogether, GoKinD
includes 3043 participants comprising 931 cases, 944 singletons, 268 pairs of parents of cases, and 316 pairs of parents of control. Accessible
as a GAIN database are 905 of the cases, 890 of the controls, 10 pairs of parents of cases and 10 pairs of parents of controls
(dbGaP <a href="./study.cgi?id=phs000018">phs000018</a> <i>Search for Susceptibility Genes for Diabetic Nephropathy in Type 1 Diabetes (GoKinD study participants), GAIN</i>).
The other parents and the remaining cases and controls are available by a separate application process through NIDDK. Interested investigators may
request the DNA collection and corresponding clinical data for GoKinD participants using the instructions and application form
available at <a href="http://www.niddkrepository.org">http://www.niddkrepository.org</a> or by contacting the Juvenile Diabetes Research Foundation.

Project description:Comparing glomerular gene expression level between mice with different susceptibilities to diabetic nephropathy, DBA/2 (susceptible) and C57BL/6 (resistant) mice, respectively. The hypothesis is that differential expression of glomerular genes regulate susceptibility to diabetic nephropathy. The results show immune related genes. Thus, glomerular inflammation may increase susceptibility to diabetic nephropathy in mice. RNA isolated from kidney glomeruli of DBA/2 and C57BL/6 mice, with or without 4 weeks diabetes induced by streptozotocin.
Project description:Analysis of ex vivo isolated lymphatic endothelial cells from the dermis of patients to define type 2 diabetes-induced changes. Results preveal aberrant dermal lymphangiogenesis and provide insight into its role in the pathogenesis of persistent skin inflammation in type 2 diabetes. The ex vivo dLEC transcriptome reveals a dramatic influence of the T2D environment on multiple molecular and cellular processes, mirroring the phenotypic changes seen in T2D affected skin. The positively and negatively correlated dLEC transcripts directly cohere to prolonged inflammatory periods and reduced infectious resistance of patients´ skin. Further, lymphatic vessels might be involved in tissue remodeling processes during T2D induced skin alterations associated with impaired wound healing and altered dermal architecture. Hence, dermal lymphatic vessels might be directly associated with T2D disease promotion. Global gene expression profile of normal dermal lymphatic endothelial cells (ndLECs) compared to dermal lymphatic endothelial cells derived from type 2 diabetic patients (dLECs).Quadruplicate biological samples were analyzed from human lymphatic endothelial cells (4 x diabetic; 4 x non-diabetic). subsets: 1 disease state set (dLECs), 1 control set (ndLECs)
