Outline of Final Research Achievements |
p62:Nrf2 double knockout mice (DKO) fed with normal diet develop spontaneous NASH in association with mature-onset hyperphagic obesity. Therefore, to elucidate the onset mechanism of NASH, we focused interests on the intestines and Kupffer cells. In the analysis of intestinal microflora, the number of gram-negative bacteria species was increased in DKO and the serum and fecal LPS concentrations were also increased. The intestinal permeability was increased in Nrf2-KO mice and DKO. The inflammatory cytokine production was increased in the Kupffer cells. It is likely that the onset mechanism of NASH is attributed to an increase in gram-negative bacteria species due to p62 deficiency and a weakness of intestinal barrier function due to Nrf2 defeciency, which in turn let an increased influx of LPS into the liver.
