(Submitter supplied) Resistance to Ras pathway inhibition is a major challenge in the treatment of colorectal cancer (CRC), but the underlying mechanisms are incompletely understood. Here we performed large-scale small molecule screens in CRC and identified inhibitors of MEK1/2 as potent activators of Wnt/beta-catenin signalling. Targeting MEK increased Wnt activity in different CRC cell lines and in the murine intestine in vivo. more...

(Submitter supplied) Wnt signaling plays a pivotal role in colorectal cancer. Intrinsic activation of Wnt by mutational events, such as mutations in the tumor suppressor gene APC, represents the most frequent initiating event in this disease background. Long truncated versions of APC retain partial functionality, which leads to a sub-maximal, “just right” activation state of Wnt signaling supposed to be beneficial for disease initiation. more...

(Submitter supplied) VGLL4, a tumor suppressor, is negative regulator of Hippo/YAP signaling. To explore the role of VGLL4 during colorectal cancer cell line, we explore microarray analysis of HCT116 cells after stable transfection of VGLL4 and shVGLL4 for 48 h.

(Submitter supplied) Tankyrase enhances beta-catenin signaling via PARsylation and subsequent degradation of Axin, a negative regulator of beta-catenin. Tankyrase inhibitors stabilize Axin and suppress beta-catenin signaling. We developed a novel tankyrase inhibitor, RK-287107. We used microarrays to elucidate the gene expression profile of human colorectal cancer cells treated with RK-287107 in a mouse xenograft model.

(Submitter supplied) Multiple myeloma (MM) is a hematological malignancy caused by accumulation of abnormal clonal plasma cells. Despite the recent development of novel therapies, relapse of MM eventually occurs due to a remaining population of drug-resistant myeloma stem cells. Side population (SP) cells exhibit cancer stem cell-like characteristics in MM; thus targeting these cells is a promising strategy to completely cure this malignancy. more...

(Submitter supplied) Mutant KRAS activates cancer stem cells (CSCs) contributing transformation of colorectal cancer (CRC) cells harboring adenomatous polyposis coli (APC) mutations. The factors mediating activation of CSCs by KRAS mutation were systematically investigated through a microarray analysis of the APC-mutated isogenic DLD-1 CRC cells harboring homogeneous wild-type KRAS (D-WT) or mutant KRAS (D-MT). The objective of the study was to find the factors specifically induced in the spheroids harboring both APC and KRAS mutations.

(Submitter supplied) Extracellular vesicles (EV) are membrane-surrounded vesicles secreted by cells that carry biologically important molecules to the target cells. EVs form a heterogenous group and they represent a novel way of intercellular communication. To study the importance of colorectal cancer (CRC)-derived EVs on stromal fibroblasts, we applied CRC patient-derived 3D organoid cultures and commercially available human colon fibroblasts. more...

(Submitter supplied) In order to examine how IOX1 affects the global Wnt target gene transcriptome in colorectal cancer cells, we performed RNA-sequencing in HCT116, DLD-1 and HCP-1 cells treated with IOX1. IOX1 led to global inhibition of Wnt target transcription in colorectal cancer cells.

(Submitter supplied) In colorectal cancer (CRC), WNT/β-catenin signaling is aberrantly activated mainly by loss-of-function mutations in adenomatous polyposis coli (APC) and is involved in tumor progression. Tankyrase inhibitors, which suppress WNT/β-catenin signaling, are under pre-clinical and clinical trials, while their resistance mechanisms remain unclear. In this study, we established tankyrase inhibitor-resistant CRC cells, JC73-RK100, from APC-mutated patient-derived CRC cells. more...

(Submitter supplied) Transcriptional profiling of Caco2 and SW480 CRC cells transfected with AURKA siRNA or a control (non-targeted) siRNA. Caco2 and SW480 both have a gain of chromosomal arm 20q, where the AURKA gene is located. The goal was to determine the effects of AURKA knock-down on global gene expression.

(Submitter supplied) Constitutive Wnt activation upon loss of Adenoma polyposis coli (APC) acts as main driver of colorectal cancers (CRC). Targeting Wnt signaling has proven difficult because the pathway is crucial for homeostasis and stem cell renewal. To distinguish oncogenic from physiologic Wnt activity, we have performed comprehensive transcriptome and proteome profiling in human colon organoids. Culture in the presence or absence of exogenous ligand allowed us to discriminate receptor-mediated signaling from the effects of CRISPR/Cas9 induced APC loss. more...

(Submitter supplied) We stratified colorectal tumor samples using a new unsupervised, iterative method based on non-negative matrix factorization (NMF). The resulting five subtypes exhibited activation of specific signaling pathways, and significant differences in microsatellite status and tumor location. We could also align three CRC cell lines panels to these subtypes.
