See legend to Table 1 for explanation of ΔCT. The more negative the ΔCT, the fewer the number of starting copies of a gene (mRNA). Number of separate animals used: CONTROL (Newborn-14 d No Ligation ) (n=12); LIGATION (Newborn-14 d Ligation) (n=7). Newborn-Ligation versus Newborn-No Ligation: Right Middle lobes from 14 days old newborns (whose PDA were ligated) were compared with Right Middle lobes from newborns (whose PDA were NOT ligated). p<0.05, LIGATION Right Middle Lobe ΔCT was significantly greater than CONTROL Right Middle Lobe ΔCT;
p<0.05, ΔCT was significantly less; - p>0.05, was not significantly different.
