Fig. 10: FMT from the 0.6-Se group activated the Nrf2 signaling pathway to inhibit the diquat-induced intestinal mitochondrial dysfunction.

a, b ROS production was determined by DHE staining (n = 7). c Mitochondrial ultrastructure was observed by TEM. d Mitochondrial ATP level in the jejunal mitochondria (n = 6). e MMP was measured by JC-1 staining in the jejunal mitochondria (n = 6). f Level of 8-OHdG in the jejunal mitochondria (n = 6). g The mtDNA copy number was analyzed by qPCR (n = 6). h The mRNA expression levels of TFAM, POLG, and POLG2 in the jejunum (n = 6). i The expression levels of NLRP3 inflammatory protein were measured by Western blot analysis (n = 3). j Nrf2 activation and expression levels of its downstream proteins measured by Western blot analysis (n = 3). Data are expressed as the fold change versus the control group (set to 1). Data are expressed as mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001.
