MetabolomicsMaslinic acid-enriched diet decreases intestinal tumorigenesis in Apc(Min/+) mice through transcriptomic and metabolomic reprogramming
Chemoprevention is a pragmatic approach to reduce the risk of colorectal cancer, one of the leading causes of cancer-related death in western countries. In this regard, maslinic acid (MA), a pentacyclic triterpene extracted from wax-like coatings of olives, is known to inhibit proliferation and indu...

TranscriptomicsAnalysis of colorectal tissue from APC- and MYH-associated polyposis patients
Expression profiling is a well established tool for the genome-wide analysis of the transcriptional activity of human neoplasia. However, the high sensitivity of this approach combined with the well-known cellular and molecular heterogeneity of cancer often result in extremely complex and extended e...

ProteomicsUSP7 is a tumor-specific WNT activator for APC-mutated colorectal cancer by mediating B-catenin deu
The tumor suppressor gene adenomatous polyposis coli (APC) is mutated in most colorectal cancers (CRC) resulting in constitutive Wnt activation. To understand the Wnt-activating mechanism of APC mutation, we applied CRISPR/Cas9 technology to engineer various APC-truncated isogenic lines. We find tha...

TranscriptomicsExpression data for 52 microsatellite stable (MSS) primary tumors from patients with proximal colon cancer.
Samples were taken from surgically resected tumor specimens from patients with proximal colon cancer. The expression profiles were determined using the Affymetrix GeneChip Human Exon 1.0 ST Array version 2. APC gene mutation status was determined using Sanger sequencing. A classifier for APC mutatio...

TranscriptomicsB-catenin deficiency, but not c-Myc deletion, suppresses the immediate phenotypes of Apc loss in the liver
Dysregulated Wnt signalling is seen in approximately 30% of hepatocellular cancers, thus finding pathways downstream of activation of Wnt signalling is key. Using cre lox technology we have deleted the the adenomatous polyposis coli tumour suppressor protein (Apc) within the adult mouse liver and ob...

TranscriptomicsThe impact of P53 loss on transcriptome changes following loss of Apc in the intestine
BACKGROUND: p53 is an important tumor suppressor with a known role in the later stages of colorectal cancer, but its relevance to the early stages of neoplastic initiation remains somewhat unclear. Although p53-dependent regulation of Wnt signalling activity is known to occur, the importance of thes...

TranscriptomicsRNA Affymetrix microarray analysis of colonic mucosal layer of Apc Min/+ mice fed or not with maslinic acid.
This experiment reports the RNA microarray data from the microarray analysis performed to the RNA isolated from colonic mucosal layer of Apc Min/+ mice. Apc Min/+ mice develop polyps in both the small and large intestine, with a greater incidence of intestinal adenomas observed in the former. We wan...

TranscriptomicsTranscription profiling of mouse mammary tumors from K14-cre; ApcCKO/+ vs control mammary glands
Many components of Wnt/β-catenin signaling pathway also play critical roles in mammary tumor development. To study the role of Apc in mammary tumorigensis, we introduced conditional Apc mutations specifically into two different mammary epithelial populations using K14-Cre (progenitor) and WAP-cre ...

ProteomicsPhenotypic heterogeneity analysis of APC-mutant colon cancer by proteomics and phosphoproteomics identifies RAI14 as a key prognostic determinant
Adenomatous polyposis coli (APC) is an important tumor suppressor and most directly related to the regulation of WNT/β-catenin signaling pathway. APC mutation has been identified as an early event in more than 80% of sporadic colorectal cancers (CRCs). However, obvious prognostic differences are obs...

ProteomicsMetabolic profiling stratifies colorectal cancer and reveals adenosylhomocysteinase as a therapeutic target
The genomic landscape of colorectal cancer (CRC) is shaped by inactivating mutations in tumour suppressors such as APC, and oncogenic mutations such as mutant KRAS. Here we used genetically engineered mouse models (GEMMs), and multimodal mass spectrometry-based metabolomics to study the impact of co...
