The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by:
Aarhus University Hospital
  Purpose
Recently EPO receptors have been found in human muscle tissue, but what is still not known is the physiological role of these receptors. In this study the researchers want to investigate if there is any effect of a acute administration of EPO on insulin resistance and/or substrate metabolism in muscle tissue.

Detailed Description:
Recently EPO receptors have been found in human muscle tissue, but what is still not known is what the physiological role of these receptors are. It has previously been shown that Growth Hormone mediate insulin resistance. The GH receptor and EPO receptor belong to the same family of cytokine receptors, and thereby share many of the same signalling pathways. In this study we want to investigate if there is a similar effect on insulin resistance and/or substrate metabolism after acute administration of EPO in human muscle tissue. Different signalling pathways are investigated på western blotting, and insulin sensitivity are measured be a hyperinsulinemic euglycemic clamp, and substrate metabolism is measured by the forearm model.
