Fig. 4From: The mechanism of nicotinamide on reducing acute lung injury by inhibiting MAPK and NF-κB signal pathwayThe effect of NAM on MAPK and NF-κB signaling pathway in lung. a–g Lung tissues from different experimental groups were obtained 12 h after LPS administration and total protein extracted. The phosphorylation levels of ERK, JNK, P38, AKT, IκBα and P65 were determined via western blot and quantitated via densitometry using β-tubulin as an internal control. The values are presented as the mean ± SD (*p < 0.05, **p < 0.001, ***p < 0.001 and ****p < 0.0001)Back to article page
