Project description:To identify the gene expression of early-onset colorectal cancer, we sampled early-onset colorectal cancer patients (age < 50) and late-onset colorectal cancer paitients (age > 70) We then performed gene expression profiling analysis using data obtained from RNA-seq of early-onset colorectal cancer tissues and late-onset colorectal cancer tissues.
Project description:Background: Causative genes for autosomal dominantly inherited familial adenomatous polyposis (FAP) and hereditary non-polyposis colorectal cancer (HNPCC) have been well characterized. There is, however, another 10-15 % early onset colorectal cancer (CRC) whose genetic components are currently unknown. In this study, we used DNA chip technology to systematically search for genes differentially expressed in early onset CRC. Keywords: disease state analysis
Project description:The hypothesis that the onset and development of colorectal cancer result from the alteration of the close cooperation of mRNA-miRNA has gained increasing popularity. We performed a multifaceted enrichment analysis of hypernetworks, taking advantage of the simultaneous evaluation of transcriptome and miRNAome, to search deregulated micro-societies of mRNAs and miRNAs involved in signaling pathways that become critical when altered in colorectal carcinogenesis.
