INSULIN-LIKE GROWTH FACTOR-I RECEPTOR ANTAGONISTS

摘要

The present invention relates to IGF-I variants that bind to the Insulin-like Growth Factor Receptor I (IGF-IR) but do not initiate signal transduction and the subsequent metabolic, growth and anti-apoptotic activities associated with this molecule and the progression of cancer. These novel variants act to block the binding of the cognate ligands but do not bind to the insulin receptor.
