doi: 10.1172/jci.insight.164694
Figure Lengend Snippet: ( A ) Immunostaining using anti-TRIM21 in liver sections from Ad-shTrim21 or Ad-Ctrl C57BL/6N mice fed a NASH diet for 30 weeks. ( B and C ) Relative hepatic mRNA expression of Trim21 ( B ), and A1cf and Khk ( C ). ( D ) Western blot analysis of indicated proteins ( n = 3 mice per group). ( E – I ) Liver weight ( E ), ratios of liver/body weight ( F ), liver TG ( G ), H&E and Oil Red O staining of liver sections ( H ), and immunoblot analysis of indicated lipogenesis genes ( I ) ( n = 3 mice per group) from mice indicated as in A . ( J–N ) Endogenous ubiquitination of SREBP1 ( J ), ChREBP ( K ), ACC ( L ), FASN ( M ), and A1CF ( N ) from liver extracts from mice indicated as in A ( n = 2). ( O ) Relative mRNA expression of de novo lipogenesis and glycolysis genes from mice indicated as in A . Scale bars: 50 μm. n represents number of replicates, 1 mouse/replicate. In all statistical plots, data are expressed as the mean ± SD; **** P < 0.0001; *** P < 0.001; ** P < 0.01; * P < 0.05. Statistical analysis for B , C , E–G , and O were carried out by 1-way ANOVA with Sidak’s post hoc analysis, n = 6 mice per group.
