Quantification of the level of PCNA (detected by western blotting) by densitometric analysis in mice treated with G6–31 by i.p. or aerosol (15 mice per group, 10 mg/kg) and in control mice (15 mice per group) (*P < 0.05 for both, Mann-Whitney test). Results are expressed as the mean ratio of PCNA normalized to β-actin and relative to the control group ± SEM

	Densitometry - Mean% (± SEM)
	I.P. G6–31 / Placebo	Aerosol G6–31 / Placebo
PCNA/β actin	− 46.80 (± 7.70)	− 31.49 (± 8.97)
	P = 0.0065	P = 0.009
