Abstract excerpt
UNLABELLED: An activated mutation in the FGFR3 gene causes ACH. To examine the effects of IGF-1, which is an important mediator of GH, on apoptosis, we analyzed a chondrogenic cell line expressing the FGFR3 mutants. Our findings that IGF-1 prevented the apoptosis through PI3K and MAPK pathways may explain how GH treatment improves the disturbed bone growth in ACH. INTRODUCTION: Achondroplasia (ACH), which is...
