Project description:The goal of this study was to analyse the effect of a 12 weeks treatment with rosiglitazone on gene expression in adipose tissue of type 2 diabetic patients. Diabetic patients were treated with rosiglitazone, agonist of PPAR gamma, during 12 weeks. Adipose tissue biopsies were taken before and after the treatment.
Project description:The goal of this study was to analyse the effect of a 12 weeks treatment with rosiglitazone on insulin sensitivity in the adipose tissue of type 2 diabetic patients. Diabetic patients were submitted to a 3 hours hyperinsulinemic- euglycemic clamp. Adipose tissue biopsies were taken before and after the clamp, labelled A & B respectively. Then, the patients were treated with rosiglitazone, agonist of PPAR gamma, during 12 weeks. After the treatment, all the patients were submitted to a second 3 hours hyperinsulinemic-euglycemic clamp. Adipose tissue biopsies were taken before and after the clamp, labelled C & D respectively.
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)
