The Wnt signaling pathway is deregulated in over 90% of human colorectal cancers. beta-Catenin, the central signal transducer of the Wnt pathway, can directly modulate gene expression by interacting with transcription factors of the TCF/LEF family. In the ...
Cyclin E is often overexpressed in cancer tissue, leading to genetic instability and aneuploidy. Cullin 3 (Cul3) is a component of the BTB-Cul3-Rbx1 (BCR) ubiquitin ligase that is involved in the turnover of cyclin E. Here we show that liver-specific ablat ...
beta-catenin and Adenomatous poliposis coli (APC) have been implicated in non-ductal pancreatic cancers. As for many other organs, several recent publications show that beta-catenin and more largely the Wnt pathway appear to function at the level of pancre ...
We recently showed that IL-13 or peroxisome proliferator activated receptor gamma (PPARgamma) ligands attenuate Candida albicans colonization of the gastrointestinal tract. Here, using a macrophage-specific Dectin-1 deficient mice model, we demonstrate tha ...
The antitumor activity of the organometallic ruthenium(II)-arene mixed phosphine complexes, [Ru(h6-p-cymene)Cl(PTA)(PPh3)]BF4 1b and [Ru(h6-C6H5CH2CH2OH)Cl(PTA)(PPh3)]BF4 2b (PTA = 1,3,5-triaza-7-phosphaadamantane), have been evaluated in vitro and compare ...
Protein kinases (PKs) are prime targets for drug discovery in a variety of diseases, including cancer and neurodegenerative pathologies. The characterisation of the kinome of the human malaria parasite Plasmodium falciparum has revealed profound divergence ...
We generated and characterized a firefly luciferase reporter mouse for the nuclear receptor farnesoid X receptor (FXR). This FXR reporter mouse has basal luciferase expression in the terminal ileum, an organ with well-characterized FXRalpha signaling. In v ...
Liver receptor homolog 1 (LRH-1) is an orphan nuclear receptor that synergizes with beta-catenin/T cell factor 4 signaling to stimulate intestinal crypt cell renewal. We evaluated here the impact of haploinsufficiency of LRH-1 on intestinal tumorigenesis b ...
Ductal cells of the pancreas form the epithelial lining of the branched tubes that deliver enzymes produced by pancreatic acinar cells into the duodenum. In addition, these cells secrete bicarbonate that neutralizes stomach acidity. During development, epi ...
Three human liver tissue samples (similar to 5 mm x 40 mm x 20 mm) were excised from a cancer patient's liver during surgery. The microradiology analysis was performed with a non-standard approach on a synchrotron. High-resolution refractive-index edge-enh ...
