36. Efeitos biomoleculares do JB-1 (um peptídeo análogo do IGF-1) em um modelo experimental de retinopatia induzida por oxigênio em ratos / Biomolecular effects of jb-1 (an igf-1 peptide analog) in a Rat model of oxygen-induced retinopathy
INTRODUCTION: Low serum insulin growth factor (IGF-1) levels at birth is a risk factor for the development of retinopathy of prematurity in extremely low birth weight infants. This may be due to its role as a permissive factor for vascular endothelial growth factor (VEGF) function in normal and pathologic vascular development. OBJECTIVE: To test the hypothes
