MetabolomicsAnalysis of colorectal adenocarcinoma tissue samples by DESI mass spectrometry imaging
Ex vivo colorectal adenocarcinoma samples were analysed by desorption electrospray ionisation using an Orbitrap mass spectrometer. The samples were analysed in negative mode over the m/z range 600-1000. Some of the samples presented in this dataset were analysed as part of [1]. The study makes avail...

Metabolomics3D DESI mass spectrometry imaging of 52 serial sections from a human colorectal adenocarcinoma
Fifty-two serial sections from a single human adenocarcinama are made available in this dataset. Four neighbouring sections were placed on a single slide and analysed together. The tissue sections were analysed by desorption electrospray ionisation mass spectrometry imaging (DESI-MSI) according to t...

MetabolomicsMetabolic Drug Response Phenotyping in Colorectal Cancer Organoids by LC-QTOF-MS
As metabolic rewiring is crucial for cancer cell proliferation, metabolic phenotyping of patient-derived organoids is desirable to identify drug-induced changes and trace metabolic vulnerabilities of tumor subtypes. We established a novel protocol for metabolomic and lipidomic profiling of colorecta...

TranscriptomicsComplex Patterns of Altered MicroRNA Expression during the Adenoma-Adenocarcinoma Sequence for Microsatellite-stable Colorectal Cancer
We searched the database of the Department of Pathology at The University of Texas MD Anderson Cancer Center and selected 21 patients who had invasive microsatellite-stable colorectal adenocarcinoma arising from a pre-existing adenoma and adjacent non-neoplastic mucosa in a resection specimen to per...

MetabolomicsReactive Oxygen Species Deficiency Due to Ncf1-Mutation Leads to Development of Adenocarcinoma and Metabolomic and Lipidomic Remodeling in a New Mouse Model of Dextran Sulfate Sodium-Induced Colitis
Inflammatory bowel disease is characterized by chronic relapsing idiopathic inflammation of the gastrointestinal tract and persistent inflammation. Studies focusing on the immune-regulatory function of reactive oxygen species (ROS) are still largely missing. In this study, we analyzed an ROS-deficie...

MetabolomicsMetabolomics-based and functional validation to explore the effect of the gut microbe-associated metabolite guanidinoacetic acid on rectal adenocarcinoma

Objective: The gut microbiota plays a crucial role in rectal adenocarcinoma (READ). Nonetheless, little is known about corresponding changes in gut microbiota–host interactions. This study aimed to identify the structure of the gut microbiota and the characteristics of faecal metabolites in patie...

TranscriptomicsTranscription profiling of human colorectal adenocarcinoma patients after Celecoxib pre-treatment
Pharmacological inhibition of cyclooxygenase-2 (COX-2) is being explored as a chemotherapeutic option because COX-2 protein expression is often elevated in many cancers. Cancer cells treated with COX-2 inhibitors, such as the selective COX-2 inhibitor celecoxib, show growth inhibition and the induc...

MetabolomicsSpatial and Untargeted Metabolomics Define Location- and Histology-Specific Metabolic Reprogramming in Colorectal Cancer

Colorectal cancer (CRC) exhibits profound molecular heterogeneity based on primary tumor location. A comprehensive understanding of the spatially resolved metabolic differences between right-sided (RCC) and left-sided (LCC) carcinomas remains elusive. Here, to eliminate the influence of inter-ind...

MetabolomicsThe Cancer-Associated Microbe Library reveals functional host-microbe interactions during colorectal cancer progression

Functional characterization of microbes which colonize CRC is impeded by a lack of bacterial strains from tumor tissues. Here, we report the Cancer-Associated Microbe Library (CAM-L), comprising more than 3,000 viable bacterial isolates, representing 121 distinct species, and 60 matching organoid...

TranscriptomicsSmall bowel adenocarcinoma copy number profiles are more closely related to colorectal than to gastric cancers
Purpose: Small bowel adenocarcinoma (SBA) is a rare cancer and consequently the number of clinical trials has been very limited due to the small numbers of patients. Chemotherapy regimens are currently rather arbitrarily chosen between either a colorectal (CRC) or a gastric cancer (GC) regimen. Chr...
