Fig. 1.

The concentration of resistin in bronchoalveolar lavage fluid (BALF; A) and serum (B) of wild-type C57BL/6 mice and mice genetically deficient in resistin (resistin-deficient mice) 24 h following cessation of a 3-h exposure to either filtered room air (air) or ozone [O₃; 2 parts/million (ppm)]. Resistin was not detectable in BALF or serum of resistin-deficient mice exposed to air or O₃ when using the immunoassay described in materials and methods. Each value is expressed as means ± SE; n = 7 to 8 mice in each group. *P < 0.05 compared with genotype-matched mice exposed to air; #P < 0.05 compared with resistin-deficient mice with an identical exposure.
