High-content, targeted RNA-seq screening in organoids for drug discovery in colorectal cancer

Maxim Norkin, Paloma Ordonez Moran

Organoids allow the recapitulation of intestinal homeostasis and cancerogenesis in vitro; however, RNA sequencing (RNA-seq)-based methods for drug screens are missing. We develop targeted organoid sequencing (TORNADO-seq), a high-throughput, high-content d ...

Genomic Instability Profiles at the Single Cell Level in Mouse Colorectal Cancers of Defined Genotypes

Maxim Norkin, Paloma Ordonez Moran

The genomes of many human CRCs have been sequenced, revealing a large number of genetic alterations. However, the molecular mechanisms underlying the accumulation of these alterations are still being debated. In this study, we examined colorectal tumours ...

Cross-Tissue Identification of Somatic Stem and Progenitor Cells Using a Single-Cell RNA-Sequencing Derived Gene Signature

Bart Deplancke, Paloma Ordonez Moran, Petra Catalina Schwalie

A long-standing question in biology is whether multipotent somatic stem and progenitor cells (SSPCs) feature molecular properties that could guide their system-independent identification. Population-based transcriptomic studies have so far not been able to ...

The most prevalent single-nucleotide substitution (SNS) found in cancers is a C-to-T substitution in the CpG motif. It has been proposed that many of these SNSs arise during organismal aging, prior to transformation of a normal cell into a precancerous/can ...

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 ...

Nature Publishing Group2016

Polycomb repressive complexes (PRCs) are among the most important gatekeepers of establishing and maintaining cell identity in metazoans. PRC1, which plays a dominant role in this context, executes its functions via multiple subcomplexes, which all contrib ...

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 ...

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 ...

Nature Publishing Group2014

Metastatic spread is an inefficient process which requires generation of supportive microenvironments in which cancer cells can survive, proliferate and escape from immune attack. These niches are induced by systemic and locally produced factors and establ ...

Autolysosomal β-catenin degradation regulates Wnt-autophagy-p62 crosstalk

Paloma Ordonez Moran

Abstract The Wnt/β-catenin signalling and autophagy pathways each play important roles during development, adult tissue homeostasis and tumorigenesis. Here we identify the Wnt/β-catenin signalling pathway as a negative regulator of both basal and stress-in ...
