Early preclinical studies in experimental diabetes demonstrated toxicities such as anemia, thrombocytopenia, splenomegaly, lymphadenopathy, lung histiocytosis, mortality with multiple organ pathology, gastrointestinal, and central nervous system toxicity
demonstrated in KO mice that the regulation of -cell number and function by GLP-1 depends on the cAMP/PKA mediated-induction of insulin-like growth factor-1 receptor (IGF-1R) expression and the increased activity of insulin-like growth factor 2 (IGF-2)/IGF-1R by an autocrine mode of action [25]
