A. Compared to saline controls, placentas from poly(I:C)-injected mothers have significantly reduced expression of IGFI and IGFBP3 mRNA and a trending decrease in GH expression [n=9 placentas per treatment group (pooled from 3 independent litters); **p < 0.001, # p = 0.24]. B. The deficits in IGFI and IGFBP3 expression observed in MIA placentas require IL-6 production [IGFI: F(2,23)=15.95; *p < 0.05; IGFBP3: F(2,23)=37.77; **p < 0.001; n=8-9 placentas per treatment group (pooled from 3 independent litters]. C. MIA placentas exhibit significantly decreased GH protein [n=7 placentas per treatment group (pooled from 3 independent litters); **p < 0.001]. D. MIA placentas exhibit significantly decreased IGFI protein, and this deficiency is dependent on IL-6 production [F(2, 17)=5.908; *p < 0.05; n=5-7 placentas per treatment group (pooled from 3 independent litters)].
