Figure 1From: Ambient particulate air pollution induces oxidative stress and alterations of mitochondria and gene expression in brown and white adipose tissues Exposure to PM 2.5 resulted in increased superoxide production in iBAT. A. DHE staining of adipose tissue sections from the mice exposed to PM2.5 or FA for 2 months. Frozen iBAT sections were stained with DHE (10 μmol/L). The oxidative red fluorescence was analyzed by fluorescent microscope. B. DHE signals were quantified by the percentage of DHE-positive areas in 5 random fields. n = 8. *P < 0.05 vs. FA.Back to article page
