| Main Objective: Rationale for the study: This project investigates the effect of ACE-inhibition on cellular metabolism by gene expression profiling of human muscle tissue, obtained by biopsy prior to and after ramipril intake. This should contribute to our understanding of the pathomechanisms involved in diabetes and the clinical effect of ACE-inhibition on patients with diabetes/metabolic syndrome. Aims of the study: To identify and describe metabolic/signaling pathways in muscle tissue which are affected or induced by ACE-inhibition. This might help to identify targets which could serve as early molecular markers of metabolic disease and success of therapy applicable in a clinical setting. ;Secondary Objective: none;Primary end point(s): Genome-wide gene expression measurements in skeletal muscle at baseline and in response to ramipril intake. Effects common to all subjects as well as intra-individual differences will be identified and analyzed. Study goal is identification of genes encoding e.g. metabolic proteins, whose expression in muscle tissue is modified by ramipril. Optional outcome parameters: Previously described single nucleotide polymorphisms in genes of the renin-angiotensin-aldosterone system may be determined from stored blood optionally if further clarification is requested to interpret potential inter-individual differences of gene expression profiles. | — |
