Colon carcinogenesis in liver-specific IGF-I-deficient (LID) mice.

Abstract excerpt

Circulating insulin-like growth factor I (IGF-I) is associated with increased risk of colorectal cancer. It is not clear, however, whether IGF-1 plays a direct causative role in colon carcinogenesis or whether it mediates the known promoting effects of insulin. The objective of this study was to determine the role of IGF-1 in colon carcinogenesis using liver-specific IGF-I deficient (LID) mice that exhibit 70%...
