Growth hormone (GH) mRNA and protein have recently been demonstrated in the rat lung throughout the period of alveolarization (day 4-14 postnatally). The functional significance of this finding was therefore assessed, by determining the effects of GH mRNA knockout using aerosolized antisense oligodeoxynucleotides (ODN) directed against the GH gene. In a preliminary experiment, the effectiveness of the antisense GH ODN was demonstrated in a lung Type II epithelial cell line (L2 cells), in which constitutive GH mRNA expression was completely abolished by GH ODN transfection. Administration of the aerosolized GH ODN to 4-day-old rats for 10 days was accompanied by a widespread presence of its delivery liposomes within lung cells. Aerosolized GH ODN treatment decreased lung concentrations of IGF (insulin-like growth factor)-1 and increased concentrations of albumin, calcyclin binding protein, superoxide dismutase, RNA binding protein motif 3, and the alpha- and beta-subunits of ATP synthase and electron transfer flavoprotein. At least 32 other proteins (identified by 2D gel electrophoresis) were also significantly affected by the antisense GH ODN treatment. By changing the lung proteome, these results indicate hitherto unsuspected autocrine/paracrine actions of GH in developmental lung function.
