doi: 10.1126/scitranslmed.abe1692
Figure Lengend Snippet: (A) Serum LPS, (B) liver Tlr4 mRNA, and (C) liver p65 protein expression in WT mice fed chow or NASH diet for 16 weeks (n = 3 to 6 per group). (D) Jag1 promoter luciferase activity in WT primary hepatocytes cotransfected with p65 (n = 4 per group), and (E) ChIP assay for NF-κB occupancy at the Jag1 promoter in livers from mice fed normal chow or NASH diet for 16 weeks (n = 4 per group). (F) Eight- to 10-week-old Tlr4flox/flox mice were transduced with AAV8-Tbg-GFP (Cre−) or AAV8-Tbg-CRE (L-Tlr4) and then fed NASH diet for 16 weeks (n = 12 to 13 per group). (G) Jagged1 protein expression, (H) expression of Notch targets, and (I) markers of HSC activation. (J) Liver Sirius red staining (n = 4 to 9 per group). (K) Control (pLive-con) or Jag1 expression (pLive-Jagged1) vectors were hydrodynamically administered to adult Tlr4flox/flox mice. Two weeks later, all mice were transduced with AAV8-Tbg-CRE and then fed NASH diet for 16 weeks (n = 8 per group). (L) Expression of Jag1 mRNA and (M) markers of HSC activity. (N) Sirius red staining (n = 5 per group). *P < 0.05, **P < 0.01, and ***P < 0.001 as compared to the indicated controls by two-tailed t tests (two groups). All data are presented as means ± SEM.
Article Snippet: The p65 expression construct ( 72 ) was obtained from Addgene (no. 23255).
