Project description:Consensus Molecular Subtypes of colorectal cancer are recapitulated in in vitro and in vivo models [primary cell lines Hubrecht Institute]
Project description:Colorectal cancer can be divided into four consensus molecular subtypes, which might associate with distinct precursor lesions. The aim of this study was to determine the subtype affiliation of two types of colorectal adenomas: tubular adenomas (TAs) and sessile serrated adenomas (SSAs) and to determine the activity of TGFβ signaling and the role of this cytokine in subtype affiliation. Adenoma samples were collected in the Academic Medical Center (AMC), Amsterdam, The Netherlands. Tubular adenomas (TAs) were obtained from familial adenomatous polyposis (FAP) patients and sessile serrated adenomas (SSAs) were collected from serrated polyposis syndrome (SPS) patients. Gene expression was analyzed for 7 sessile serrated adenomas (SSA) and 9 tubular adenomas (TA).

Project description:We have compared the gene expression profiles of primary colorectal cancers and colorectal liver metastases within the framework of the consensus molecular subtypes. This series represents a subset of the primary tumor samples.
Project description:Matrisome-focused integrative omics analysis reveals stromal phenotypes associated with consensus molecular subtypes in colorectal cancer
This reseaerch is conducted using colorectal cancer.
TMT 11plex experiment
Project description:We have analyzed transcriptomic intra-tumor heterogeneity among 2-4 multiregional samples from each of 98 primary colorectal cancers. We investigated the level and prognostic value of intra-tumor heterogeniety of the consensus molecular subtypes, and identified subtypes more robust to heterogeneity based on genes with uniform expression levels across tumor regions.
