Identification of a novel rat hepatic gene induced early by insulin, independently of glucose.

ABSTRACT: We used mRNA differential display to identify new genes induced early after exposure to insulin. Our screening strategy was based on the comparison of gene expression during the time course of insulin induction in the liver of 12-day-old suckling rats both in vivo and in vitro. A novel, early induced transcript, EIIH, was identified that encodes a 353-amino-acid protein with several features suggesting that it may be secreted or bound to membranes. EIIH is also distantly related to a variety of LRR (leucine-rich repeat) proteins. Insulin treatment increased EIIH mRNA levels in the hepatocytes of suckling, fasted adult and STZ (streptozotocin)-treated diabetic rats, where insulin was required to maintain the basal level of EIIH expression. EIIH expression was induced during the suckling/wea
