Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
The human C-type lectin Reg3a (HIP/PAP) is an antimicrobial peptide that kills Gram-positive bacteria. Reg3a preserves gut microbiota homeostasis, reinforces intestinal barrier function and thereby helps to fight induced colitis in mice.

Description
We have recently developed a new generation of induced stem cells that we have called induced Tissue Stem cells (iTSCs) which are generated by using low doses of non-integrative vectors encoding several embryonic reprogramming factors permitting to de-differentiate the cells without passing through a pluripotent state. ITSCs are thus multipotent stem cells rather than pluripotent stem cells. Using this technology we have produced endodermic iTSCs by de-differentiation of murine hepatocytes and shown that they are able to differentiate in vitro and in vivo into tissues restricted to endodermic layers. We report the gene expression profiles of two subclones of murine hepatocytes-reprogrammed iTSCs and of hepatocytes parental cells and murine embryonic stem cells (D3).

Description
Hepatitis C Virus (HCV) core protein plays a major role in HCV mediated liver pathologies. We have previously reported that HCV core variants isolated from tumoral (T) and non-tumoral (NT) livers were capable to alleviate Smad transcriptional activity and to shift TGF- responses from tumor suppressor effects to tumor promotion.

The objective of this study is to assess the effects of the Serum Response Factor deletion on the cardiac gene expression program at different time points after the deletion (day 8 and day 25) and to compare the response of SRF-deficient heart and control heart to phenylephrine, an alpha-adrenergic agonist triggering cardiac hypertrophy.

Description
ZBTB4 is a mammalian transcription factor with Zinc fingers and a BTB/POZ domain, which can bind methylated CpGs, as well as certain unmethylated consensus sequences. ZBTB4 is frequently downregulated in human cancers, but it is unclear whether this is a cause or consequence of transformation. To investigate the role of ZBTB4 in normal and pathological conditions, we generated Zbtb4-/- mice

Description
Pulmonary endothelial dysfunction plays an integral role in mediating the initiation and progression of pulmonary vascular remodelling, an important feature of pulmonary arterial hypertension (PAH). Our aim was to decipher the gene expression program of endothelial cells derived from circulating endothelial progenitor (EPCs) to gain insight into the pathological process of PAH associated with systemic sclerosis (SSc), which is the most extreme vascular phenotype of this disease.

Description
Hematopoietic stem/progenitor cells (HSPCs) are at the basis of the hematopoietic hierarchy. Their ability to self-renew and differentiate is strictly controlled by molecular signals produced by their surrounding micorenvironments composed of stromal cells. HSPCs first emerge in the AGM (Aorta Gonads Mesonephros) region, amplify in the fetal liver (FL) and are maintained in the adult bone marrow (BM). To further characterize the molecular program of the HSPC niches, we have compared the global transcriptome of HSPC-supportive and non/less-supportive stromal clones established from the AGM, FL and BM.

Description
Primary liver tumours include hepatocellular carcinomas (HCC), cholangiocarcinomas (CC) and a group of rare tumours exhibiting biliary and hepatocytic differentiation called combined hepatocholangiocarcinomas (cHCC-CC). To better define this latter group, we take advantage of a series of these tumours based on their morphological characteristics and we performed transcriptional analysis allowing thereafter global comparison with published data. We show that most cHCC-CCs express progenitor cell traits, are committed to biliary lineage and are mainly associated to the activation of Wnt/beta-catenin and TGFbeta signalling pathways. Wnt/beta-catenin pathway activation in cHCC-CC is evidenced by the expression of both its direct targets such as LEF1 and EPCAM. In addition, extracellular matrix (ECM) genes and ECM-remodelling genes which are upon the control of TGF profibrotic program were found up-regulated in cHCC-CC. Interestingly, we show that CC and most cHCC-CC share characteristics associated to a subtype of poorly differentiated HCC suggesting that these tumours could originate from a stem/progenitor cell. The plasticity of these cells may explain the phenotypical heterogeneity of these tumors with the maintenance of some hepatocellular differentiation features such as albumin expression. Interestingly, this is shared by at least one third of CC, raising the hypothesis of a potential continuum between CC, cHCC-CC and poorly differentiated HCC.
