Project description:Long non-coding RNAs (lncRNAs) are a large class of non-protein-coding transcripts that are over 200nt in length. LncRNAs have emerged as key regulator of biological process involved in the development and progression of bladder cancer. Bladder cancer is one of the most common genitourinary malignancies worldwide, with approximately 429,800 new cases and 165,100 deaths annually in the world. To identify critical lncRNAs that contributes to the progression of bladder cancer, Next generation sequencing (NSG) was performed in five paired high-grade muscle invasive bladder cancer (MIBC) and normal adjacent tissues (NAT), and in five lymph node (LN)-positive and LN-negative bladder cancer tissues. Our results indicate that the differential expressed lncRNAs in both MIBC tissues and LN-positive tissues associated in a variety of biological functions, such as metastasis.
Project description:To explore the molecular mechanism underlying NONO-mediated lymphatic metastasis inhibition in bladder cancer, a genome-wide RNA-sequencing was conducted to compare gene expression profiles of UM-UC-3 cells with NONO knockdown and control.
Project description:The crosstalk between tumor cells and LECs triggers the LN metastasis in bladder cancer (BCa), but the underlying mechanisms are not completely understood. Previously, we identified that BCa-secreted extracellular vesicles (EVs)-packaged lncRNAs mediated the communication with LECs and promoted LN metastasis. To evaluate whether EV-packaged lncRNAs triggered the LN metastasis of BCa, next-generation sequencing (NGS) to the global expression profiles of lncRNAs was utilized in the urinary EVs (urinary-EV) of five MIBC patients and five healthy volunteers.
Project description:Lung cancer is the leading cause of cancer-related death worldwide, and non-small cell lung cancer (NSCLC) accounts for approximately 85% of lung cancers. Lymphatic metastasis serves as a predominant NSCLC metastatic route and an essential predictor of patient prognosis. Recently, circular RNA (circRNA) has emerged as critical mediator in various tumor initiation and progression. To identify essential circRNA that involves in the lymphatic metastasis of NSCLC, Next generation sequencing (NSG) was performed in 6 paired NSCLC tissues and normal adjacent tissues (NAT).
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.
