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:Proliferative diabetic retinopathy (PDR) is a vision-threatening disorder characterized by the formation of cicatricial fibrovascular membranes leading to traction retinal detachment. Despite the recent advance in the treatment of PDR such as vitreoretinal surgery with use of anti-vascular endothelial growth factor (VEGF) drug as an adjunct, it still remains vision-threatening disease. In order to identify genes associated with the pathogenesis of PDR, we performed gene expression analyses in fibrovascular membrane in patients with PDR using DNA microarray technology.

Despite the recent advance in the treatment of PDR such as vitreoretinal surgery with use of anti-vascular endothelial growth factor (VEGF) drug as an adjunct, it still remains vision-threatening disease. In order to identify genes associated with the pathogenesis of PDR, we performed gene expression analyses in fibrovascular membrane in patients with PDR using DNA microarray technology. This study was approved by the Ethics Committee of the Kyushu University Hospital and Fukuoka University Chikushi Hospital, and the surgical specimens were handled in accordance with the ethical standards of the 1989 Declaration of Helsinki. All patients gave informed consent before inclusion in the study. Fibrovascular membranes (FVMs) were surgically dissected from the retinal surface with horizontal scissors of patients with PDR undergoing pars plana vitrectomy. These specimens were classified into active and inactive according to the clinical findings of neovascularization (NV) in the FVMs.Total RNA were extracted from the FVMs. RNA from human retina was obtained from Clontech (Palo Alto, CA).

Project description:Control (n=27) and proliferative diabetic retinopathy (n=23) vitreous samples were treated as biologically distinct individuals or pooled together and aliquoted into technical replicates. Quantitative mass spectrometry with tandem mass tag labeling was used to identify proteins in individual or pooled control samples to determine technical and biological variability. To determine effect size and perform power analysis, control and proliferative diabetic retinopathy samples were analyzed across four 10plexes. Pooled samples were used to normalize the data across plexes and generate a single data matrix for downstream analysis.
