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:The goal of this study is to investigate the cell type-specific targets of miR-126-3p in human lung microvascular endothelial cells (HLMVEC). Following the transfections of HLMVEC with non-targeting negative controls, miR-126 mimics, or miR-126 antisense inhibitors, we calculated the copy number concentration of miR-126 in each sample and performed genome-wide RNA sequencing. Plotting the gene expression data for each transfection condition (Scramble, 126-OE and 126-KD) against their respective miR-126 concentrations, we performed a linear regression analysis to discover genes that were the most sensitive to changes in miR-126 levels. We identified 1258 genes that were upregulated and 1436 genes that were downregulated by miR-126-3p. Further comparison between the downregulated genes in HLMVEC and targets predicted by online databases including TargetScan and miRDB revealed 6 genes as potential direct targets of miR-126-3p. Our study is the first to report targets of miR-126-3p in HLMVEC and demonstrate the effect of miR-126 level alteration on the HLMVEC global transcriptome. These results add to the diverse functions of miR-126-3p in different endothelial cell types and provide basis for the development of cell type-specific treatment for lung diseases.

Project description:Fish, JE, Santoro, MM, Morton, SU, Yu, S, Yeh, RF, Wythe, JD, Ivey, KI, Bruneau, BG, Stainier, DYR, and Srivastava, D. (2008). miR-126 Regulates Angiogenic Signaling and Vascular Integrity. Developmental Cell 15, 272-284. Precise regulation of the formation, maintenance, and remodeling of the vasculature is required for normal development, tissue response to injury, and tumor progression. How specific microRNAs intersect with and modulate angiogenic signaling cascades is unknown. Here, we identified microRNAs that were enriched in endothelial cells derived from mouse embryonic stem (ES) cells and in developing mouse embryos. We found that miR-126 regulated the response of endothelial cells to VEGF. Additionally, knockdown of miR-126 in zebrafish resulted in loss of vascular integrity and hemorrhage during embryonic development. miR-126 functioned in part by directly repressing negative regulators of the VEGF pathway, including the Sprouty-related protein SPRED1 and phosphoinositol-3 kinase regulatory subunit 2 (PIK3R2/p85-?). Increased expression of Spred1 or inhibition of VEGF signaling in zebrafish resulted in defects similar to miR-126 knockdown. These findings illustrate that a single miRNA can regulate vascular integrity and angiogenesis, providing a new target for modulating vascular formation and function. Human umbilical vein endothelial cells, which express high levels of miR-126, were utilized to identify mRNA targets of miR-126. Cells were electroporated with 15 nmol of an antisense morpholino that blocks the processing of the miR-126 pri-cursor. A non-targeting morpholino (15 nmol) was used as a control. RNA was isolated 72 hr following electroporation and arrays were performed using Affymetrix Human Gene 1.0 ST arrays. Analysis was performed on three biological replicates of control morpholino and miR-126 antisense morpholino transfected cells
