Insulin-like growth factor-I (IGF-1) mRNA levels and chicken muscle growth.
Insulin-like Growth Factor-1 is a key regulator of muscle development and metabolism in birds and other vertebrate species. In a first part, the present paper sums up the specificities of the IGF system in birds and especially those related to muscle development. In a second part, it reviews available data obtained with avian genetic or nutritional models. Data obtained by comparing genetic mod...
متن کاملPolymorphism of insulin-like growth factor I gene among chicken breeds in Egypt.
The insulin-like growth factor I (IGF-I) regulates growth, protein synthesis, and cell proliferation and differentiation in vertebrates. Polymorphisms of IGF-I gene transcripts of three breeds of chicken were assessed. The associations of these polymorphisms with the growth rate of the studied breeds were also evaluated. Total RNA was isolated from chicken livers, and the IGF-I gene was amplifi...
متن کاملEffects of insulin and insulin-like growth factor I on growth of human leukemia cells in serum-free and protein-free medium.
Human myeloid leukemia cells (HL60) and malignant lymphocytes (Namalwa) were grown in protein-free, Fe-supplemented media and used to study growth responses to insulin and insulin-like growth factor 1 (IGF-I). HL60 cells previously grown in serum-free medium containing microgram quantities of insulin showed an 18-fold reduction in cumulative cell production when grown without insulin. However, ...
متن کاملMaternal serum insulin-like growth factor-I.
The recent report on maternal insulin-like growth factor-I is very interesting. Yang et al. concluded that “maternal serum IGF-I is significantly related to GA, maternal BW, and BMI during pregnancy.” In fact, there are some previous reports on this issue. Pathmaperuma et al. made a completely different observation. In their report, it was reported that serum IGF-I “did not correlate with newbo...
متن کاملSingle nucleotide polymorphisms of the chicken insulin-like factor binding protein 2 gene associated with chicken growth and carcass traits.
Five single nucleotide polymorphisms (SNP) of the chicken insulin-like factor binding protein 2 (IGFBP2) gene were selected to genotype a F2 designed population with restriction fragment length polymorphisms and single stranded-conformation polymorphisms. The associations of the SNP and their haplotypes with chicken growth and carcass traits were analyzed. Results showed that the difference ind...
