Project description:Although many protein-coding genes have been identified to be aberrantly expressed in gallbladder cancer, the mechanism that account for the development and progression of gallbladder cancer remains unclear. In recent years, long noncoding RNAs have been shown to play vital roles in mammalian cell biology. In this study, we found that a small number of lncRNAs that are aberrantly expressed. A ten chip study using total RNA recovered five separate gallbladder cancer tissues and five matched adjacent gallbladder normal tissues
Project description:Liver invasion and metastasis often occur in gallbladder cancer (GBC). We established a liver metastasis mouse model using NOZ cells for two round intrasplenic injection. We acquired a highly metastatic subclone of NOZ cells, we named it LiM2-NOZ(second-round liver metastasis NOZ) cells. Then we characterized the long noncoding RNAs (lncRNAs) and mRNAs that differentially expressed in NOZ and LiM2-NOZ cells.

Project description:1. Evaluate the diagnostic value of long noncoding RNA (CCAT1) expression by RT-PCR in peripheral blood in colorectal cancer patients versus normal healthy control personal.
2. Evaluate the clinical utility of detecting long noncoding RNA (CCAT1) expression in diagnosis of colorectal cancer patients & its relation to tumor staging.
3. Evaluate the clinical utility of detecting long noncoding RNA (CCAT1) expression in precancerous colorectal diseases.
4. Compare long noncoding RNA (CCAT1) expression with traditional marker; carcinoembryonic antigen (CEA) and Carbohydrate antigen 19-9 (CA19-9) in diagnosis of colorectal cancer.
