Project description:Background: Duodenal adenoma/adenocarcinomas are rare, and the global gene expression changes associated with the initial stages of carcinogenesis of these neoplasms have not been elucidated. Results: To comprehensively analyze genetic markers and pathways specific to early-stage duodenal adenoma/adenocarcinomas, transcriptional profiles of 4 fresh-frozen non-ampullary duodenal adenoma/adenocarcinomas and surrounding duodenal normal mucosa were compared. Key features of gene expression analysis demonstrated a strong correlation between these tumors and colorectal adenomas, as well as the Wnt/β-catenin pathway. These results shed new light on the transcriptional changes that occur during the early stages of duodenal tumorigenesis. All samples were obtained prior to treatment in order to minimize effects of cauterization, and immediately fresh-frozen.
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.
Project description:sequential changes in gene expression profiles in the gastric adenoma-carcinoma sequence by analyzing eight patient-matched gastric normal mucosa, adenomas and carcinomas. We examined gene expression changes during the gastric adenoma-carcinoma sequence in 26 snap-frozen samples (normal mucosa, adenoma, and carcinoma samples from eight patients and two additional carcinomas) by oligonucleotide microarray

Project description:Gene expression profiling was carried out in 7 matched colon adenoma samples and normal mucosa to characterize the molecular mechanisms relevant to the etiology ofadenoma and human colorectal carcinoma development. Whole-transcriptome RNA sequencing of the 7 matched colon adenoma samples and normal mucosas.
Project description:We evaluated the profile of miRNA expression in 6 colorectal adenoma (CRA), 6 colorectal adenocarcinoma (CRC) and 6 matched normal mucosa (NOR) using the Exiqon miRCURY LNA microRNA array,7th generation. We found that global dysregulated miRNAs between colorectal lesions and normal mucosa. Our findings implicates that dysregulation of miRNAs may play important role in the carcinogenesis and present therapeutic targets for CRC.
