Project description:Autophagy deficiency caused by conditional knockout of Atg7 results in severe hepatitis accompanied by abundant accumulation of p62. p62 stablizes Nrf2 by disrupting the association between Keap1 and Nrf2. To understand the pathogenesis of hepatitis under the autophagy deficiency, we examined gene expression profiles of livers from Atg7-null, Nrf2-null and Atg7-Nrf2 double mutant mice. Eight week old Atg7F/F:Mx1-Cre mice and Atg7F/F:Mx1-Cre:Nrf2-/- together with control mice were injected with pIpC. At 4 weeks after pIpC injection, total RNAs were purified from each mouse liver.

Project description:To identify Nrf1-dependent and Nrf2-dependent genes in the liver, we examined the gene expression profiles of Nrf1 Alb-CKO, Nrf2 knockout and Keap1 knockdown mouse livers by microarray analyses. Total RNAs from Nrf1dN/-::Alb-Cre, Nrf1dN/+, Nrf2-/-, Nrf2+/+, Keap1KD/- and Keap1KD/+ mouse livers were used for the microarray analyses.

Project description:Expression array analysis of mice livers with conditional deletion of autophagy related protein 7 (Atg7). Whole RNA from mice livers of 2 month old control (Atg7 FF), Olig1-CRE:Atg7 FF (conditional deletion in hepatocytes) and Alb-CRE:Atg7 FF (conditional deletion in hepatocytes/cholangiocytes) were analyzed. The results provide insight into the gene expression profile and role of autophagy in hepatocytes or hepatocytes/cholangiocytes in hepatic growth regulation and hepatocarcinogenesis.
Project description:Transcriptome analysis of NesCre:Atg7 conditional knockout mice. Autophagy plays an important role in regulating protein metabolism and tissue homeostasis. Recent studies have reported that neural stem cell-specific Atg7 knockout mice (NesCre:Atg7f/f cKO mice) exhibit neonatal lethal due to severe neurodegeneration. However, the precise mechanisms of how neuronal fate is regulated by the autophagic pathway have not been elucidated. Here, we performed microarray experiments to analyze the changes in gene expression patterns in NesCre:Atg7 cKO mice. As a result, we could find a lot of candidate genes changed by Atg7 deficiency.
