Tribbles-1 regulates hepatic lipogenesis through post-transcriptional regulation of C/EBPα [array]
Ontology highlight
ABSTRACT: Comparison of gene expression in livers of either WT mice or mice with hepatic specific deletion of the gene Tribbles1. Animal groups were both Trib1 cKO mice homozygous for a floxed allele of Trib1. Mice aged 8-10 weeks were treated with adeno associated virus (AAV) encoding Cre recombinase (AAV_Cre) or no gene (AAV_null). The WT group is mice treated with AAV_Null, the liver-specific KO group treated with AAV_Cre. Gene expression data was then used in Ingenuity Pathway analysis to attempt to identify upstream transcription factors that might be responsible for the gene expression changes observed. All animals were 8-10 weeks of age, and all animals were homozygous for the floxed allele of Trib1. WT animals were treated with AAV_Null, Trib1 liver specific KO mice were treated with AAV_Cre. Mice were euthanized at 1-week post injection of AAV, and RNA collected from whole liver tissue.

Project description:We report ChIP-Seq data for C/EBPa in livers of mice with liver-specific KO (LSKO) of Trib1 as compared to WT controls, or in livers of mice overexpressing C/EBPa via adeno-associated virus (AAV) as compared to controls. 8-10 week old Trib1 flox/flox mice treated with AAV_Null (WT) or AAV_Cre (LSKO); 8-10 week old C57B/6 WT mice treated with AAV_Null or AAV_Cebpa.

Project description:We have shown that intravenous injection of HDAC3 floxed mice with adeno-associated virus (AAV) expressing Cre depletes hepatic HDAC3, upregulates lipogenic gene expression, and causes fatty liver. When AAV-Flag-HDAC3 wild-type (WT) is co-injected along with AAV-Cre, the exogenous HDAC3 is expressed at endogenous levels and can completely rescue fatty liver phenotype. Here we profile transcriptome of the rescued WT livers in comparison with HDAC3-depleted (KO) livers. 4-months old C57BL/6 male mice were co-injected with AAV-Cre or AAV-Cre plus AAV-Flag-HDAC3. Mice were fed ad libitum and harvested at 5 pm (ZT10) at 2-weeks post-injection. Liver total RNA was extracted and hybridized to Affymetrix Mouse Gene 1.0ST array.

Project description:We used AAV as a vector to deliver hGRβ to C57BL/6 mouse liver. We collected liver samples for microarray analysis to investigate any phenotype as well as the underlying specific signaling pathway. In particular, we would like to determine if and how hGRβ overexpression in liver affects mGRαâs gene transcription profile in C57BL/6 mice. Three replicates for each group: untreated WT liver, AAV-GFP treated liver, and AAV-hGRB treated liver.
Project description:Using the 10X Genomics platform, we performed single cell RNA-sequencing on activated T cells from LCMV clone 13-infected control or CD4-cre+ Trib1-floxed mice to determine how Trib1 regulates T cell population dynamics during chronic infection.
Project description:The experiment evaluates the therapeutic effect brain injected AAV9-IDS (Adeno-associated virus 9 encoding IDS enzyme) treatment in a mouse model of Mucopolysaccharidosis Type II (MPSII). Microarrays were performed in order to compare the transcriptional profiling after the treatment. Three groups were analyzed, wild type (WT) mice, MPSII mice treated with AAV-NULL (AAV vector alone) and MPSII mice treated with AAV-IDS (vector encoding IDS enzyme). Four months after vector administration (at 6 months of age), animals were sacrificed and tissues were harvested and processed. RNA isolated from the encephalon of three groups of mice was analysed using the Affimetrix® microarray platform
Project description:Foxl2 is a forkhead transcription factor expressed only in the female, but not in the male gonad. We have created mice homozygous mutant for the Foxl2 gene (KO) as well as mice carrying a conditional mutant Foxl2 allele (floxed). The expression profiles of conventional Foxl2 knockout and wildtype ovaries were compared at P3, using the Affy Mouse Genome 430 2.0 Array. Adult wildtype and conditional mutant (Foxl2 floxed x RosaCre-EBD treated with tamoxifen) ovaries were compared to adult wildtype testes using the Affymetrix Mouse Gene 1.0 ST Array. Both experiments (KO/WT P3 and Mutant/WT/Testis Adult were also compared to each other.)
Project description:Mcl1-conditional mice were injected with AAV-LP1-Cre to delete endogenous MCL-1 and with AAV-LP1-Mcl1Flag (FLINT) or AAV-LP1-GFP (wt control). After 14 days, mitochondria were harvest from mouse livers and subjected to anti-FLAG immunoprecipitation. Immune complexes were subjected to LC MS/MS mass spectrometry. Two independent liver mitochondria immunoprecipitations were run in parallel.
