(Submitter supplied) Canonical Wnt signaling output is mediated by β-catenin, which interacts with LEF/TCF transcription factors and recruits a general transcriptional activation complex to its C-terminus. Its N-terminus binds BCL9/9L proteins, which bind co-activators that in mammals contribute to fine-tuning the transcriptional output. We found that a BCL9/9L-dependent gene expression signature was strongly associated with patient outcome in colorectal cancer and that stem cell and mesenchymal genes determine its prognostic value. more...

(Submitter supplied) We have analysed transcriptional effects of BRAF(V600K) in the intestinal epithelium of transgenic mice that harbour an inducible BRAF(V600K) transgene. Mice used in this experiment were compound transgenic for a stem-cell specific Lgr5-EGFP Reporter and either an inducible TdTomato-2A-BRAF(V600K) transgene or an inducibe TdTomato-luciferase transgene.

(Submitter supplied) To understand global gene expression patterns of mouse livers upon dual-oncogene transfection, RNA sequencing and analysis were conducted on liver samples from Shp2F/F or Shp2∆H (Shp2F/F:Alb-cre) mice hydrodynamically injected with the combination of Met/β-Catenin or Met/PIK3CA .

(Submitter supplied) Insufficient repair of DNA lesions results in the acquisition of somatic mutations and displays the driving force in cancerogenesis. Ribonucleotide incorporation by eukaryotic DNA polymerases occurs during every round of genome duplication and represents by far the most frequent type of naturally occurring DNA lesions. RNAse H2 removes misincorporated ribonucleotides from genomic DNA in a process termed ribonucleotide excision repair (RER). more...

(Submitter supplied) Constitutive activation of the Wnt pathway leads to adenoma formation, an obligatory step towards intestinal cancer. In view of the established role of Wnt in regulating stemness, we attempted the isolation of cancer stem cells (CSCs) from Apc- and Apc/KRAS-mutant intestinal tumours. Whereas CSCs are present in malignant Apc/KRAS–mutant carcinomas, they appear to be very rare (<10-6) in the benign Apc–mutant adenomas. more...

(Submitter supplied) Breast cancer is the most frequent cancer in women and consists of heterogeneous types of tumours that are classified into different histological and molecular subtypes1-3. Pik3ca and p53 are the two most frequently mutated genes and are associated with different types of human breast cancers4. The cellular origin and the mechanisms leading to Pik3ca-induced tumour heterogeneity remain unknown. Here, we used a genetic approach in mice to define the cellular origin of Pik3ca-derived tumours and its impact on tumour heterogeneity. more...

(Submitter supplied) Here we identify HOXA5 as an important repressor of intestinal stem cell fate in vivo and identify a reciprocal feedback between HOXA5 and Wnt signaling. HOXA5 is suppressed by the Wnt pathway to maintain stemness and becomes active only outside the intestinal crypt where it inhibits Wnt signaling to enforce differentiation. In colon cancer, HOXA5 is down-regulated and its re-expression induces loss of the cancer stem cell phenotype preventing tumor progression and metastasis. more...

(Submitter supplied) We assessed the impact of intestinal epithelial XBP1 in coordinating epithelial DNA damage responses. As our data revealed that low XBP1 activity in the context of chronic DNA damage is associated with both reduced p53 pathway activity and formation of tumors with metastaic potential in-vivo, we performed RNA sequencing of intestinal organoids (H2b/Xbp1fl/fl, H2bΔIEC, H2b/Xbp1ΔIEC, H2b/p53∆IEC) to identify a transcriptional program downstream of p53 that drives the tumorigenic in-vivo phenotype.

(Submitter supplied) Colorectal cancer is treated with antibodies blocking epidermal growth factor receptor (EGF-R) but therapeutic success is limited. EGF-R is stimulated by soluble ligands, which are derived from transmembrane precursors by ADAM17-mediated proteolytic cleavage. In mouse intestinal cancer models in the absence of ADAM17, tumorigenesis was almost completely inhibited and the few remaining tumors were of low grade dysplasia. more...

(Submitter supplied) Gain-of-function mutation of PIK3CA represents one of the most common oncogenic events in human malignancy, making PI3K an attractive target for cancer therapy. Despite the great promise of targeted therapy, drug resistance is likely to develop, causing treatment failure. To elucidate resistance mechanisms to PI3K-targeted therapy, we constructed a mouse model of breast cancer conditionally expressing PIK3CA-H1047R. more...

Gene expression signature of the genome engineered organoids were similar to that of adenoma organoids. more...

(Submitter supplied) The majority of hepatocellular carcinoma (HCC) develops in the background of chronic liver inflammation caused by viral hepatitis and alcoholic or non-alcoholic steatohepatitis. However, the impact of different types of chronic inflammatory microenvironments on the phenotypes of tumors generated by distinct oncogenes is largely unresolved. To address this issue, we generated murine liver tumors by constitutively active AKT-1 (AKT) and b-catenin (CAT) followed by induction of chronic liver inflammation by 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) and carbon tetrachloride (CCl4). more...

(Submitter supplied) Competitive cell-interactions play a crucial role in quality control during development and homeostasis. Here we show that cancer cells use such interactions to actively eliminate wild-type intestine cells in enteroid monolayers and organoids. This apoptosis-dependent process boosts proliferation of intestinal cancer cells. The remaining wild-type population activates markers of primitive epithelia and transits to a fetal-like state. more...
