Challenges of Monitoring IGF-1 Levels: Complications and Shortfalls of Existing Assays The crucial role IGF-1 plays in human growth and development, the number of different clinical conditions that it is associated with, combined with the potential for its abuse in sports and its status as a marker for GH abuse, makes detecting its differential expression extremely important

34 EphA4 knockout mice have dramatically reduced body size and impaired GHR signaling: they have normal levels of GH mRNA expression in the pituitary but have reduced plasma IGF1 and reduced IGF1 mRNA expression in the liver
