MAPK phosphorylation and the expression of PCNA and cyclin D1 in the lung tissues. (A) Western blots of lung homogenates. (B) Immunofluorescence of lung sections. PCNA was labeled by Cy3 (red) and cytokeratin or CD31 was labeled by FITC (green). (C) Western blots of Nox2 KO lung homogenates. The levels of the protein bands detected by Western blot were quantified and normalized to the levels of α-tubulin detected in the same sample. *P < 0.05 for indicated values versus vehicle values in the same graph.
