(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) Wnt/β-catenin signaling is activated in colorectal cancer (CRC) and is involved in CRC growth. Tankyrase, a poly(ADP-ribose) polymerase family member, destabilizes Axin and positively regulates the Wnt/β-catenin signaling. Tankyrase inhibitors efficiently suppress CRC cell proliferation. We established 320-IWR cells, which showed resistance to tankyrase inhibitor IWR-1, from human CRC COLO-320DM cells. more...

(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) Tankyrase, a poly(ADP-ribose) polymerase family member, regulates multiple cellular processes. Tankyrase inhibitors efficiently suppress APC-mutated colorectal cancer (CRC) cell proliferation. To examine the mechanism of anti-proliferative effect of tankyrase inhibitors (G007LK and RK582), we analyzed gene expression profiles of patient-derived APC-mutated CRC cells (JC21 and JC475) left untreated or treated with 0.3 µM G007LK or RK582 for 24 h by cDNA microarray analysis.

(Submitter supplied) Prdx2 is the thioredoxin-dependent peroxidase that reduces H2O2 using reducing power NADPH in the presence of thioredoxin and thioredoxin reductase. Prdx2 plays an important role in growth. factor signaling in mammlian cells. Therefore, we examined the gene expression in colon adenocarcinoma cell line HT29 after Prdx2 depletion. Prdx2 depletion resulted in a significant alteration on gene expression, including protein synthesis, metabolisms, and cell cycle.

(Submitter supplied) FVB mice were engineered to express wild-type human cyclin E under control of the human surfactant C promoter (CEO mice; Ma et al, PNAS 2007). These mice develop spontaneous lung tumors, which were shown to be adenocarcinoma by histological analysis. Here we compare whole-genome RNA expression levels between the tumors and normal lung of 4 CEO mice as well as 4 nontransgenic animals.

(Submitter supplied) Background and Aims: Staging inadequately predicts metastatic risk in colon cancer patients. We used a gene expression profile derived from invasive murine colon cancer cells that were highly metastatic in an immunocompetent mouse model to identify colon cancer patients at risk for recurrence in a phase I, exploratory biomarker study. Methods: 55 colorectal cancer patients from Vanderbilt Medical Center (VMC) were used as the training dataset and 177 patients from the Moffitt Cancer Center were used as the independent dataset. more...

(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) Aberrant activation of Wnt/β-catenin signaling is observed in numerous cancers. In hepatocellular carcinoma activating mutations in CTNNB1 (20-25%) or loss of function mutations in AXIN1 (10%), AXIN2 (2%) and APC (1-2%) are observed. All these mutations lead to aberrant stabilization of β-catenin, which constitutively activates downstream Wnt/β-catenin target genes and triggers a genetic program resulting in tumor formation. more...
