Fig. 7From: Landscape of lipidomic metabolites in gut-liver axis of Sprague–Dawley rats after oral exposure to titanium dioxide nanoparticlesThe correlation between the level of MDA and differential metabolites induced by oral exposure to TiO2 NPs in serum and liver. A MDA was significantly correlated with 11 kinds of differential metabolites in liver (p < 0.05), 7 of which were positively correlated. B MDA was significantly correlated with 21 kinds of differential metabolites in serum (p < 0.05), 20 of which were positively correlated. Lipid peroxidation was closely related to abnormal lipid metabolism induced by oral exposure to TiO2 NPsBack to article page
