Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: Adiponectin has been shown to possess potent anti-oxidative properties in various experimental conditions. However, its anti-oxidative effects and underlying mechanisms have not been reported in liver cells. Herein, we investigated the effects of globular adiponectin (gAcrp) on LPS-stimulated reactive oxygen species (ROS) production and its mechanisms underlying in human hepatic cells (HepG2).', 'Intracellular ROS production was determined by fluorescence of 5-chloromethyl-2,7-dichlorodihydrofluorescein diacetate (CM-H2DCFDA). NADPH oxidase-dependent ROS formation was determined by lucigenin-derived chemiluminescence. Messenger RNA expression level of target genes was determined by quantitative RT-PCR and protein expression was measured by Western blot analysis.', 'LPS-induced increase in ROS production was prevented by pretreatment with gAcrp in HepG2 cells. Furthermore, gAcrp treatment suppressed LPS-induced activation of NADPH oxidase and increase in mRNA and protein expression of Nox-4. We also found that adiponectin increased expression of FoxO3A and HO-1 and ablation of either of these genes partially restored suppression of LPS-induced ROS production and NADPH oxidase activation by gAcrp, indicating the vital role of FoxO3A and HO-1 signaling in the inhibition of ROS production and NADPH oxidase activation by gAcrp.
Output:
Does globular adiponectin attenuate LPS-induced reactive oxygen species production in HepG2 cells via FoxO3A and HO-1 signaling?
