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)
Project description:We perfomed transcriptomic and methylomic analysis of sural nerve biopsies from type 2 diabetic patients with neuropathy. Sural nerve transcriptomic and methylomic profiles were integrated and subsequent biological meaning investigated using KEGG pathway analysis of overlapping differentially expressed genes (DEGs) and differentially methylated genes (DMGs). A gene interation network was also generated including DEGs and DMGs, and common biological pathways were identified.

Project description:Diabetic keratopathy(DK) is a common ocular complication of diabetes that seriously threatens diabetic patients' vision. Here, by sequencing of microRNAs (miRNAs) from diabetic and normal TG tissues, we aimed to uncover potential miRNAs involved in the pathogenesis of diabetic corneal neuropathy.
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:Human patients were enrolled in a weight loss clinic and followed. Patients were male and female, normoglycemic,pre-diabetic and diabetic and with and without neuropathy.
