Transcriptomic profiles of advanced colorectal adenomas from 40 Korean patients

Project description:We report the RNA-seq data of 40 advanced colorectal adenoma patients form Dongguk University Ilsan International Hospital. The polyps with a diameter of 1cm or greater were regarded as advenced colorectal adenoma and obtained through colonoscopy. The data consist of 22 tublar adenoma, 6 tublovillous adenoma, 5 sessile serrated adenoma/polyp, 1 traditional serrated adenoma, intramucosal adenocarcinoma, neuroendocrine tumor, hyperplastic polyp, inflammatory polyp, high grade dysplasia, and atypical glands with adjacent hyperplastic mucosa.

Expression data from human colonic biopsy samples (adenoma-carcinoma)

Project description:Whole genomic microarray analysis was performed in order to identify gene expression profile alterations focusing on the dysplastic adenoma-carcinoma transition. Our aims were to determinate characteristic transcript sets for developing diagnostic mRNA expression patterns for objective classification of benign and malignant colorectal diseases and to test the classificatory power of these markers on an independent sample set. Total RNA was extracted from colonic biopsy samples of histologically negative patients and of patients with adenoma or colorectal cancer and were hybridized on Affymetrix HGU133 Plus 2.0 microarrays

Identification of an intermediate signature that marks the initial phases of colorectal adenoma-carcinoma transition

Project description:The colorectal adenoma-carcinoma sequence describes the stepwise progression from normal to dysplastic epithelium and then to carcinoma; only a small proportion of colorectal adenoma (CRA) progresses to colorectal carcinoma (CRC). Presently, endoscopic intervention is used on patients with CRAs of high grade dysplasia, diameters > 1 cm, or villous components > 25% who are at higher risk than other CRA sufferers. During the process, biopsy samples were taken for conventional histological diagnosis, but poor pathomorphological sensitivity and specificity greatly limit the diagnostic accuracy. Unfortunately, there are no reliable molecular criteria available that can predict the potential development of CRA to CRC. In present study, we use microarrays to detail the global programme of gene expression underlying the gradual progress of colorectal adenoma-carcinoma sequence.

lncRNA and mRNA expression profile in colorectal adenoma and cancer

Project description:We evaluated the profile of lncRNA and mRNA expression in 6 colorectal adenoma (CRA), 6 colorectal adenoma (CRC) and 6 matched normal mucosa (NOR) using the Exiqon miRCURY lncRNA and mRNA array,7th generation. We found that global dysregulated lncRNA and mRNAs between colorectal lesions and normal mucosa. Our findings implicates that dysregulation of lncRNA and mRNAs may play important role in the carcinogenesis and present therapeutic targets for CRC.

mRNA expression data from adenoma, gene modified, and colorectal cancer organoid.

Project description:We established human colorectal tumor organoids from benign adenoma, primary colorectal cancer or metastasized colorectal cancer. The gene signature of tumor organoids associated with their tumor progression status. We also generated genome-edited organoids from human intestinal organoids recapitulating adenoma-carcinoma sequence. Gene expression signature of the genome engineered organoids were similar to that of adenoma organoids. This result indicated multiple (up to five) genetic mutations were insufficient for gene expression reprogramming of colorectal cancer. We used microarrays to detail the global program of gene expression in human colorectal tumor organoids and artificially mutation introduced organoids.

MicroRNA signatures of colonic adenomas according to histology

Project description:Adenomatous polyps adjacent to colorectal cancer (CRC) were found to exhibit two distinct microRNAs (miRs) patterns from normal mucosa to low- and separately, to high-grade dysplasia; presence in screen-detected adenoma of non-cancer patients is unknown. Global miR expression was performed on biopsies obtained from 109 healthy patients undergoing screening/surveillance colonoscopy. Included were normal mucosa (NM); hyperplastic polyp (HP); tubular adenoma (TA), tubulovillous adenoma, with or without, high-grade dysplasia (TVHG) and serrated-polyps; sessile serrated adenoma (SSA) and traditional serrated adenoma (TSA). Logistic regression was used to model miRs predictive of histology and CRC risk. We identified 99 miRs that differed across five histologic groups (FDR=0.05) and that accurately separated on histology (Concordance Index (CI)=0.96). In HPNM, miRs-145, -143, -107a, -23b, and -24 were upregulated whereas miRs-663, -1268, -320b, -1275, and -671 where overexpressed in TVHGs (FDR P<0 .05). The expression of miR-145 and -30a showed high accuracy to separate low from high-risk polyps independent of serrated status (CI= 97.1%; AUC 93.4%). For TSAs, miR-125b and -199a were uniquely downregulated relative to HPNMs and miR-335 discriminated between non-serrated and serrated histology. Histologically advanced polyps from non-cancer patients share miR alterations with those reported for CRC and high-grade adenoma adjacent to tumor including downregulation of immune regulatory miRs-125 and -199a in TSAs; polyp that frequently present with in situ carcinoma. These data extend evidence that miR patterns of high-risk adenoma are detectable in subset of screen-detected adenoma for which measurement may be useful in in adenoma risk stratification.

Genetic lineages of colorectal adenocarcinomas with and without adenoma components

Project description:We tried to examine whether the de novo colorectal carcinomas (CRCs) without an adenoma component can be discriminated from those deriving from adenoma by DNA copy-number alteration profile. The unsupervised clustering of DNA copy-number profiles of 112 colorectal cancer samples, using large-sized (≥ 9 probes) genes, disclosed 4 clusters: Clusters 1, 3, and 4 correspond to carcinoma with an adenoma component. Cluster 2 and some samples in cluster 3 correspond to carcinoma without adenoma component. Our approach suggested that Cluster 2 may represent de novo CRCs since penetrance plots were very different between cluster 2 and the other clusters. Adenocarcinoma in cluster 3 have higher potential for lymph node metastasis than those in cluster 1 and 4 and can derive from clusters 1/4 tumors.
