  • Title: Insulin-like growth factor mRNA expression in tissues of lean and obese male SHFF/Mcc-fa(cp) rats.
    Author: De Sevilla L, McCune SA, White ME.
    Journal: Comp Biochem Physiol B Biochem Mol Biol; 1994; 109(2-3):371-82. PubMed ID: 7553350.
    Abstract:
    No differences were detected in serum IGF-I levels between lean and obese male SHFF/Mcc-fa(cp) rats expressing non-insulin-dependent diabetes mellitus (NIDDM). In contrast, serum insulin levels, and blood glucose levels were significantly elevated in obese as compared to lean littermates (P < 0.05), indicating that the obese animals were diabetic. Northern blot analysis of total tissue RNA using labeled cDNAs for IGF-I and IGF-II revealed a decrease in liver and adipose IGF-I mRNA expression in the obese littermates while IGF-II mRNA expression was decreased only in adipose tissue of obese animals as compared to lean littermates.
