Fizz1 overexpression has no effect on bleomycin-induced fibrosis in the lung. CCSP/- and CCSP/Fizz1 mice were exposed to saline or bleomycin (0.15U) via the I.T. route, with pulmonary fibrosis assessed at day 10. (A) Masson Trichrome stained lung sections at 10X magnification. Scale bar 200 μm. (B) Total lung weights were measured in all groups at day10 post-bleomycin. (C) The lung collagen deposition, expressed as micromoles of hydroxyproline per lung. The above data is an average of two independent experiments with the total 7–14 mice per group. Statistical significance is measured using one way ANOVA (n = 7-14/group).
