Project description:DNA methylation of 23 familial adenomatous polyposis tumors. Infinium HumanMethylation450 BeadChip was used to obtain DNA methylation profiles across 485,577 CpG sites.
Project description:FAP is an autosomal-dominant inherited disease caused by germline mutations in the APC gene 1. Two major FAP phenotypes, CFAP and AFAP, can be distinguished based on polyp numbers and age of onset. CFAP is characterized by the presence of hundreds to thousands of polyps. About half of these patients develop adenomas by age 15, and 95% develop adenomas by age 35. AFAP patients exhibit a milder phenotype than CFAP patients; AFAP is characterized by fewer polyps, later adenoma onset, and lower CRC risk. We used microarrays to analyze the expression profiles of organoids established from three CFAP and two AFAP patients.
Project description:Here, we generated bulk RNA-seq data on colon organoids derived from both healthy and familial adenomatous polyposis patients. We related findings observed within this dataset to differential expression findings from a publicly available colorectal cancer cohort.
