Figure Lengend Snippet: VEGF levels were estimated by ( A ) western blot and ( B ) ELISA. ( C ) PCNA levels estimated by western blot. Data were normalized with tubulin. ( D ) Representative images of PCNA immunohistochemistry staining in the nucleus is shown for CS-exposed mice (CSE) and CS-exposed and LGF-treated mice (CSE+LGF). Scale bars = 50 µm. LGF promoted an increase of PCNA+ cells as showed in the bar graph. ** P <0.01 vs. air-exposed mice; ¥ P <0.05 vs. CS-exposed mice (n = 5 per group). Data are presented as mean ± SEM.
Article Snippet: Using total protein extracts from lung tissue homogenates, ELISA was performed with a mouse specific VEGF ELISA kit (ref: CSB-E04756m; CUSABIO), as indicated in the manufacturer’s protocol.
