Global hepatic gene expression data from PPARa liver KO, PPARa liver WT, PPARaKO and WT male mice treated or not with Fenofibrate

ABSTRACT: Fenofibrate is a specific agonist of the nuclear receptor PPARa. To identify the gene expression under the strict dependence of hepatic PPARa activity, we generated a new mouse strain of PPARa-specific deletion in hepatocyte (albumin-Cre+/- Pparaflox/flox or LKO) and we compared them to total Ppara KO (KO), wild-type (WT) and liver WT (albumin-Cre-/- Pparaflox/flox or LWT) mice. We used microarrays to detail the global programme of gene expression in liver of Ppara LKO, LWT, Ppara KO and WT male mice.

We used microarrays to detail the global programme of gene expression in liver of Ppara LKO, LWT, Ppara KO and WT male mice. There are 36 liver samples, each from an individual mouse. The samples are from Ppara liver KO (LKO), Ppara KO (KO), wild-type (WT) and liver WT (LWT) male mice of 14 week-old from the same genetic background (C57Bl/6J) treated with Fenofibrate (100 mg/kg/day) or vehicle (aqueous solution of gum Arabic 3%) by daily gavage for 10 days. n= 4 mice for LKO, LWT and WT genotypes treated with vehicle; n=3 for KO mice treated with vehicle; n=5 mice for LWT, LKO and KO genotypes treated with fenofibrate; n=4 WT mice treated with fenofibrate. All mice were sacrified at ZT14.

Global hepatic gene expression data from PPARa liver KO, PPARa liver WT, PPARaKO and WT male mice fed ad libitum, fasted for 24 hours and re-fed

Project description:If the function of the nuclear receptor PPARa is well-known during a prolongated fasting, its hepatic biological function during feeding and refeeding conditions still needs to be investigated. Moreover, in vivo data collected so far on PPARa function during fasting were obtained using the total Ppara KO transgenic mouse model. To identify genes whose expression is under the strict dependence of hepatic PPARa activity, we generated a new mouse strain of PPARa-specific deletion in hepatocyte (albumin-Cre+/- Pparaflox/flox or LKO) and we compared them to total Ppara KO (KO), wild-type (WT) and liver WT (albumin-Cre-/- Pparaflox/flox or LWT) mice under three nutritional challenges. We used microarrays to detail the global programme of gene expression in liver of Ppara LKO, LWT, Ppara KO and WT male mice fed ad libitum, fasted for 24 hours and refed. There are 52 liver samples, each from an individual mouse. The samples are from Ppara liver KO (LKO), Ppara KO (KO), wild-type (WT) and liver WT (LWT) male mice of 8 week-old from the same genetic background (C57Bl/6J) fed ad libitum, fasted for 24 hours, fasted for 24 hours and then refed 24 hours more with glucose added in water (200g/l). In fed condition (Fed), n= 3 mice for LKO, LWT genotypes, n= 5 for KO and n= 4 fot WT; in fasting condition (Fas), n=5 for LKO, LWT and WT genotypes and n= 3 for KO; in refeeding condition (Ref), n= 5 for LKO, KO and WT genotypes and n= 4 for LWT. All mice were sacrified at ZT14.

Global hepatic gene expression data from PPARa liver-specific KO and PPARa liver wild-type male mice fed ad libitum

Project description:To identify genes whose expression is under the strict dependence of hepatocyte PPARa activity, we used a mouse strain of PPARa-specific deletion in hepatocyte (albumin-Cre+/- Pparaflox/flox or LKO) and we compared them to their liver WT littermates (albumin-Cre-/- Pparaflox/flox or LWT) fed ad libitum or fasted for 24 hours.

Gene expression data of the liver in hepatocyte-specific Phgdh knockout mice

Project description:Live hepatocyte-specific Phgdh KO (LKO) mice were generated by introducing Albumin-Cre transgene into Phgdh flox/flox (Floxed) mice. LKO mice exhibited mild obesity and impaired glucose intolerance at 30 weeks old.

Effect of beta3 adrenergic activation on liver gene expression profile in mice (C57Bl/6J) expressing hepatocyte PPARalpha or not

Project description:Pparα hepatocyte-specific knockout (Pparαhep-/-) mice were generated at INRAE’s rodent facility (Toulouse, France) by mating the floxed-Pparα mouse strain with C57BL/6J albumin-Cre transgenic mice to obtain albumin-Cre+/-Pparαflox/flox mice (LKO). Albumin-Cre-/-Pparαflox/flox (Pparαhep+/+) littermates were used as controls (LWT). Twelve week-old mice were transferred in a ventilated cabinet at the specific temperature of 30°C (thermoneutrality) 2 weeks before experiments. Mice were fed ad libitum or fasted at ZT0 and given beta3 adrenergic receptor agonist: CL316243 ((3 mg/kg body weight; Sigma Aldrich) = Beta3) or vehicle (0.5% carboxymethyl cellulose in sterilized water)=vehicle) by gavage at ZT10 and sacrificed at ZT16.

Serotonin signals through a gut-liver axis to regulate hepatic steatosis

Project description:Purpose: While various functions of peripheral serotonin are known, the direct role of serotonin in regulating hepatic lipid metabolism in vivo is not well understood. We studied whether serotonin directly acts on liver to regulate lipid metabolism. Methods: Methods: 12 weeks aged liver-specific Htr2a KO (Albumin-Cre+/-; Htr2aflox/flox, herein named Htr2a LKO) mice and wildtype (WT) littermates were fed a high-fat diet (HFD, 60% fat calories) for 8 weeks. Results: Hepatic lipid droplet accumulation, NAFLD activity score, and hepatic triglyceride levels were dramatically reduced in HFD-fed Htr2a LKO mice compared to WT littermates. Conclusions: Gut-derived serotonin is a direct regulator of hepatic lipid metabolism via a gut TPH1-liver HTR2A endocrine axis. And shows promise as a novel drug target to ameliorate NAFLD with minimal systemic metabolic effects.

Ago2-RIP-chip in Dicer WT and KO macrophages

Project description:To determine the spectrum of miRNA targets regulated following Dicer deletion, we performed argonaute 2 (AGO2)-RNA Immunoprecipitation (RIP)-microarray in bone marrow-derived macrophages (BMDMs) from LysM-Cre/Dicerflox/flox/Apoe–/– and LysM-Cre/Dicerwt/wt/Apoe–/– mice. This analysis combined with miRNA profiling in Dicer wild type (WT) and knockout (KO) BMDMs may help to identify the miRNA targets regulated by Dicer deletion.
