A RAGE mRNA expression was elevated in lungs from RAGE TG mice compared to WT controls in the absence of SHS exposure (p = 0.02). RAGE mRNA was significantly elevated in WT (p = 0.02) and RAGE TG mice (p = 0.03) following exposure to SHS compared to room air (RA) controls. Expression of RAGE transcripts were not detected in RAGE KO mice regardless of exposure. The mRNA was normalized to β-actin (n = 6 mice per group) and representative data are shown. B Analysis of RAGE protein demonstrated that RAGE TG animals expressed significantly more RAGE protein compared to controls (p = 0.02). SHS exposure significantly increased RAGE protein expression in WT (p = 0.01) and RAGE TG mice (p = 0.04) compared to RA controls while RAGE KO animals had no expression. Blots were densitometrically normalized to β-actin and representative blots were cropped and presented
