Interestingly, as predicted by the Igfbp4-ko and the pappa-ko animal models described previously, a human PAPP-A2 gene defect with growth phenotype was recently reported as detailed below (43)
By analyzing how drugs affect cellular and tissue-level processes, researchers can elucidate mechanisms of action and refine strategies for drug design and screening
