Project description:Given the role of lncRNAs and mRNAs in tumor pathogenesis, we set out to identify transcripts that potentially drive colorectal tumorigenesis. To do this, we performed microarray analysis on matched colorectal tumor and non-tumor samples from 6 colorectal cancer patients, and determined their lncRNA and mRNA expression profiles with Agilent microarrays (Arraystar Human LncRNA Array v3.0).
Project description:Long noncoding RNAs (lncRNAs) have been shown to play critical roles in the biology of various cancers. However, their expression patterns and biological functions in human colorectal cancer (CRC) remain largely unknown. The aim of this study was to explore lncRNA profiles in CRC and investigate key lncRNAs involved in CRC tumourigenesis and progression.
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:To determine the mRNA expression profile of colorectal cancer cell line HCT116 transfected with lncRNA-SPRY4-IT1 overexpression vector, we performedd gene expression microArray analysis to examine the expression of mRNAs.
Project description:Long noncoding RNAs (lncRNAs) play important roles in the tumorigenesis and metastasis of colorectal cancer (CRC). This study used a lncRNA microarray to analyze the aberrant lncRNA expression profiles in CRC tissues compared with paired adjacent normal tissues as well as CRC with regional lymph nodes metastasis compared with CRC without regional lymph nodes metastasis.
Project description:LncRNA plays an important role in gene regulation, but its impact on the pathogenesis of colorectal cancer and the biological function of cancer cells is unclear. In this study, we will use the next generation sequencing technique to study the differences of the expression profiles of lncRNA and mRNA in colorectal cancer tissues, analyzing the differentially expressed genes by GO/KEGG enrichment, and predicting the new lncRNAs’ function. Our results revealed that Comparing with the nontumor colorectal tissues, 1019 lncRNAs (512 upregulated, 507 downregulated) and 3221 mRNAs (1606 upregulated, 1615 downregulated) were differentially expressed in tumor colorectal tissues (fold change>2 and P<0.05).
