(Submitter supplied) We established a mouse model, in which transcription factor Tcfap2c can be activated in an inducible and reversible manner in somatic tissues, taking advantage of the tetracycline-dependent regulatory system. Induction of the transgene led to robust expression in all tissues (except brain and testis) and lead to rapid mortality within 3-7 days. In the liver, accumulation of microvesicular lipid droplets and breakdown of major hepatic metabolism pathways resulted in steatosis.

(Submitter supplied) Trophoblast stem cells (TS cells), derived from the trophectoderm (TE) of blastocysts, require transcription factors (TFs) and external signals (Fgf4, Activin/Nodal/Tgfb) for self-renewal. While many reports have focused on TF networks that regulate embryonic stem cell (ES cell) self-renewal and pluripotency, little is know about TF networks that regulate self-renewal in TS cells. To further understand transcriptional networks in TS cells we used chromatin immunopreciptiation and DNA microarray analysis (ChIP-chip) to investigate targets of TFs Ap-2g (Tcfap2c), Eomes, Ets2, and Gata3, and a chromatin remodeling factor, Brg1 (Smarca4). more...

(Submitter supplied) The complexity of gene regulation has created obstacles to defining mechanisms that establish the patterns of gene expression characteristic of the different clinical phenotypes of breast cancer. Transcription factor TFAP2C plays a critical role in the regulation of both estrogen receptor-alpha (ERα) and c-ErbB2/HER2 (Her2). Herein, we performed chromatin immunoprecipitation and direct sequencing (ChIP-seq) for TFAP2C in four breast cancer cell lines representing different clinical phenotypes. more...

(Submitter supplied) Mutations in the gene encoding lipin 1 cause hepatic steatosis in fld mice, a genetic model of lipodystrophy. Lipin 1 appears to be highly involved in the control of fatty acid metabolism. Lipin 1 is most often located in the nucleus, but other studies suggest that lipin also has effects in the cytoplasm. However, the molecular function of lipin 1 is unclear. To evaluate the effects of activation of the lipin 1 system in liver, lipin 1beta was overexpressed in mouse liver using an adenoviral vector. more...

(Submitter supplied) Apolipoprotein E-knock out (apoE-KO) mouse is known as a model animal for atherosclerosis accompanied by spontaneous hypercholesterolemia. When apoE-KO mice were fed a chow supplemented with 1.25% cholesterol (high-Chol diet), cholesterol and bile acids were highly increased in the liver within a week. However, the amount of triacylglycerol (TG) in very low-density lipoprotein (VLDL), but not in the liver, was reduced by 78%. more...

(Submitter supplied) Perilipin A (PeriA) exclusively locates on adipocyte lipid droplets and is essential for lipid storage and lipolysis. Adipocyte specific overexpression of PeriA caused resistance to diet-induced obesity and resulted in improved insulin sensitivity. In order to better understand the biological basis for this observed phenotype we performed DNA microarray analysis on white adipose tissue (WAT) from PeriA transgenic (Tg) and control wildtype (WT) mice.

(Submitter supplied) Overexpression of the AP-2γ transcription factor in breast tumours has been identified as an independent predictor of poor outcome and failure of hormone therapy, even in ER positive, ErbB2 negative tumours; markers of a more favourable prognosis. To understand further the role of AP-2γ in breast carcinoma, we have used an RNA interference and gene expression profiling strategy using the MCF-7 cell line as a model for ER positive, ErbB2 negative tumours with AP-2γ overexpression. more...

(Submitter supplied) *Objectives:* In addition to their well-known role in the control of cellular proliferation and cancer, cell cycle regulators are increasingly identified as important metabolic modulators. Genome wide association studies identified SNPs near the cell cycle regulator CDKN2A/p16INK4a (p16) as strongly associated with risk of developing type 2 diabetes (T2D). T2D is associated with numerous perturbations of hepatic lipid and glucose metabolism. more...

(Submitter supplied) 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. more...

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.
