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.
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: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:BRCA1 nestin CRE conditional knockout cortrices of P7 animals were compared to wildtype littermates to characterize the mutant phenotype. Keywords: expression
Project description:BRCA1 nestin CRE conditional knockout cortrices of P7 animals were compared to wildtype littermates to characterize the mutant phenotype. Keywords: expression BRCA1 conditional knockouts using nestin CRE and a null allele with an inverted neo cassette at the 5' end of the exon 11 of BRCA1 on one floxed allele flanking exons 5-13. Cortices of 3 wildtype animals were compred to 3 BRCA cKO at postnatal day 7.
Project description:We performed Spatial transcriptomics (Visium) using the 10X Genomics platform to investigate the role of the autophagy-related protein ATG7 in the context of nontuberculous mycobacterial (NTM) infection. ATG7 in innate immune cells plays a critical role in controlling NTM infection and protecting lung tissue from pathological inflammation. This study represents single-cell analysis of Mice deletion of Atg7 in innate immune cells and reveals the importance of ATG7 in mediating antimicrobial responses during infection and its essential role in host defense mechanisms against NTM.
