摘要: The interaction of the IGF-1 receptor with its ligands (IGF-1, IGF-II and insulin at supraphysiological concentrations) plays a major role in normal development control both abnormal growth (for reviews, see Werner et al., 1991 Lowe, 1991). importance is especially supported by seminal experiments Efstratiadis co-workers (DeChiara 1990, personal communication). These investigators have shown that targeted disruption gene results progeny, which, birth, has body weight 70% wild type litter mates. When genes are disrupted homologous recombination, homozygous mutant embryos birth only 30% Thus, it can be stated activation (IGF-1 or IGF-II) accounts for embryonal murine growth.
