摘要：

The activated type I insulin-like growth factor (IGF-IR) increases the expression of Id1 proteins in mouse embryo fibroblasts (MEF). Up-regulation depends on a functional receptor and on multiple pathways originating from different domains of the receptor. In MEF, Id1 protein expression is also up-regulated by serum and certain oncogenes. Signaling through Stat3 plays an important, but not exclusive, role in the up-regulation of Id1 protein levels. In all instances, the increase in Id1 protein expression is paralleled by a corresponding increase in Id1 promoter activity, as measured with a reporter gene. (C) 2002 Elsevier Science (USA).
