New and improved methods for integrated models of metabolism and gene expression

The beginning of the 21st century was marked by the advent of disruptive technologies, which ushered an era of groundbreaking advances in fundamental sciences, carried by the great pace at which computational capabilities spread and evolved. But the new ce ...

Neutrophils suppress tumor-infiltrating T cells in colon cancer via matrix metalloproteinase-mediated activation of TGF beta

Freddy Radtke, George Coukos, Nadine Fournier, Mauro Delorenzi, Marc-Olivier Sauvain, Amber Dawn Bowler, Markus Germann

High T-cell infiltration in colorectal cancer (CRC) correlates with a favorable disease outcome and immunotherapy response. This, however, is only observed in a small subset of CRC patients. A better understanding of the factors influencing tumor T-cell re ...

On null hypotheses in survival analysis

Mats Julius Stensrud, Pal Christie Ryalen

The conventional nonparametric tests in survival analysis, such as the log-rank test, assess the null hypothesis that the hazards are equal at all times. However, hazards are hard to interpret causally, and other null hypotheses are more relevant in many s ...

SPROUTY-2 represses the epithelial phenotype of colon carcinoma cells via upregulation of ZEB1 mediated by ETS1 and miR-200/miR-150

Paloma Ordonez Moran

SPROUTY-2 (SPRY2) is a modulator of tyrosine kinase receptor signaling with receptor-and cell type-dependent inhibitory or enhancing effects. Studies on the action of SPRY2 in major cancers are conflicting and its role remains unclear. Here we have dissect ...

Flexure-based multi-degrees-of-freedom in-vivo force sensors for medical instruments

Simon Nessim Henein, Charles Baur, Marine Chantal Elisabeth Geneviève Clogenson, Sebastian Krzysztof Fifanski, José Luis Rivera Gutiérrez

This paper presents novel multi-degrees-of-freedom force sensors based on flexures used as mecano-optical transducers (named flexure body) and white light interferometers used as opto-electrical transducers. Together, these transducers make up a load cell ...

HOXA5 Counteracts Stem Cell Traits by Inhibiting Wnt Signaling in Colorectal Cancer

Paloma Ordonez Moran, Caroline Dafflon

Hierarchical organization of tissues relies on stem cells, which either self-renew or produce committed progenitors predestined for lineage differentiation. Here we identify HOXA5 as an important repressor of intestinal stem cell fate in vivo and identify ...

Natural compounds boldine and menthol are antagonists of human 5-HT

Rudolf Hovius

Background Impaired 5-HT3 receptor function is likely involved in the pathogenesis of functional gastrointestinal disorders (FGID) and 5-HT3 receptor antagonists are effective treatments for chemotherapy-induced nausea and vomiting (CINV) and irritable bow ...

SPROUTY2 is a β-catenin and FOXO3a target gene indicative of poor prognosis in colon cancer

Paloma Ordonez Moran, Anja Irmisch

SPROUTY2 (SPRY2) is an intracellular regulator of receptor tyrosine kinase signaling involved in cell growth, differentiation and tumorigenesis. Here, we show that SPRY2 is a target gene of the Wnt/beta-catenin pathway that is abnormally activated in more ...

The Intestinal Nuclear Receptor Signature With Epithelial Localization Patterns and Expression Modulation in Tumors

Johan Auwerx, Kristina Schoonjans

BACKGROUND & AIMS: The WNT-adenomatous polyposis coli system controls cell fate in the intestinal epithelium, where compartment-specific genes tightly regulate proliferation, migration, and differentiation. Nuclear receptors are transcription factors funct ...

Serotonin receptor diversity in the human colon: Expression of serotonin type 3 receptor subunits 5-HT3C, 5-HT3D, and 5-HT3E

Rudolf Hovius

Since the first description of 5-HT3 receptors more than 50 years ago, there has been speculation about the molecular basis of their receptor heterogeneity. We have cloned the genes encoding novel 5-HT3 subunits 5-HT3C, 5-HT3D, and 5-HT3E and have shown th ...
