Geranylgeranylacetone (GGA)-induced expression of heat shock protein 70 (HSP70) in the lungs. a Representative immunoblotting data for HSP70 and β-actin expressions 24 h after the administration of GGA or vehicle alone (vehi) under normoxia or hyperoxia are shown. b Expression levels of HSP70 normalized by β-actin signal were calculated by densitometry and compared between the vehicle-treated group (open bars) and the 500 mg/kg GGA-treated group (closed bars). vehi vehicle administration. Data shown represent means ± the standard error of the mean (SEM) (normoxia/vehicle group: n = 8; normoxia/GGA group: n = 7; hyperoxia/vehicle group: n = 6; hyperoxia/GGA group: n = 7). Comparison between the indicated groups (*p < 0.05, **p < 0.01)
