Project description:aCGH analysis of murine transgenic liver tissues affected with HCC, hybridized with age (12 months) and sex matched alb cre mice. Keywords: Array comparative genomic hybridization analysis (aCGH). Independent HCC of MCL1-/- mice were hybridized with pooled wt mice. Mclâ1flox/flox mice (C57BL/6 background) were obtained from the Dana Farber Cancer Institute, Boston, USA (Opferman JT et al., Nature 2003) and bred to heterozygous Albumin-Cre mice (C57BL/6 background) which led to hepatocyte-specific deletion of Mcl-1. The mice develop severe chronic liver damage (Vick B et al., Hepatology, 2009).

Project description:Microarray analysis of liver tissue from WT SIRT6 and conditional knockout of SIRT6 using albumin-Cre (SIRT6Co/Co ;Alb-Cre) at 2 and 8 months of age RNA was extracted from mouse liver tissue at 2 and 8 months of age. RNA from three pairs of WT SIRT6 and SIRT6Co/Co ;Alb-Cre mice was combined and hybridized to Affymetrix mouse gene 1.0 ST arrays.
Project description:We have previously shown that the HyD-LIR-Venus probe can specifically inhibit selective autophagy by suppressing the interaction of LIR-containing selective autophagy substrates and receptors with ATG8-family proteins in vivo. We generated hepatocyte-specific HyD-LIR-Venus-expressing mice (HyD-LIRflox/flox; Alb-Cre) by crossing HyD-LIRflox/flox mice, in which HyD-LIR-Venus is expressed under CAG promoter in a Cre-recombinase-dependent manner, with Alb-Cre transgenic mice that express Cre under the control of the Albumin promoter. We performed quantitative proteomic analysis of the livers of 5-week-old HyD-LIRflox/flox and HyD-LIRflox/flox; Alb-Cre mice using the RTS-SPS-MS3 method on Tribrid mass spectrometry.
Project description:aCGH analysis of murine transgenic liver tissues affected with HCC, hybridized with age (18 months) and sex matched C57BL/6 mice. Moreover, 18months old C57BL/6 livers were hybridized with independent 18 months old C57BL/6 livers for control. Keywords: Array comparative genomic hybridization analysis (aCGH).

Project description:FBXL6 is frequently over-expressed in human hepatocellular carcinoma (HCC). However, it is still unknown the underlying mechanisms by which FBXL6 promotes HCC. In this study, we compared ubiquitinated protein profiles among a panel of liver tissue samples (including HCC, adjacent tissues and normal tissues) from Fbxl6LSL-fl/+; Alb-cre mice and Alb-cre mice by proteomics and ubiquitomics analysis. There are many proteins with ubiquitination in FBXL6 overexpressed HCC, suggesting ubiquitination may play a critical role in FBXL6-mediated HCC.

Project description:Hepatocellular carcinoma (HCC) is the fastest growing cause of cancer-related mortality with limited therapies. While endoplasmic reticulum (ER)-stress and the unfolded protein response (UPR) are implicated in HCC, the involvement of the UPR-transducer activating transcription factor 6 alpha (ATF6α) remains unclear. We generated hepatocyte specific n-ATF6 overexpression transgenic mice via Cre-mediated recombination. At 3 months age, livers from the transgenic mice and their wild type controls were harvested for ATAC-sequencing.
Project description:To elucidate the functional roles of sMafs in the adult liver, we conditionally targeted the sMaf genes using a transgenic complementation rescue approach. MafF-/-::MafG-/-::MafK-/- (F0G0K0) mice are embryonic lethal but can be rescued by complementation of transgenic MafG expression under the regulation of the MafG regulatory domain (MGRD). Therefore, we rescued F0G0K0 mice using a MGRD transgenic mouse line with a MafG gene flanked with loxP (fMafG) sequences so that the MafG gene could be deleted by Cre-mediated recombination. The Albumin(Alb)-Cre transgenic mice were used to delete fMafG gene specifically in the liver. The genotype used are MafF-/-::MafG-/-::MafK-/-::MGRD-fMafG::Alb-Cre (liver-specific sMaf CKO) and MafF-/-::MafG+/-::MafK-/-::MGRD-fMafG::Alb-Cre (control).
