Project description:To explore the potential involvement of circular RNAs (circRNAs) in pancreatic ductal adenocarcinoma (PDAC) oncogenesis, we conducted circRNA profiling in six pairs of human PDAC and adjacent normal tissue by microarray. Our results showed that clusters of circRNAs were aberrantly expressed in PDAC compared with normal samples, and provided potential targets for future treatment of PDAC and novel insights into PDAC biology. Analyze circular RNA expression in pancreatic ductal adenocarcinoma (PDAC) by microarray platform.
Project description:Pancreatic ductal adenocarcinoma, caused by activating mutation in K-Ras, is an aggressive malignancy due to its early invasion and matastasis. Ral GTPases, negatively regulated by RalGAP, are activated downstream of Ras and play a crucial role in development and progression of pancreatic ductal adenocarcinoma. However, the underlying mechanisms remain unclear. We used microarrays to detail the global programme of gene expression underlying the human pancreatic ductal adenocarcinoma cell line, MIA PaCa-2 with RalGAPβ deficiency or not, and identified distinct classes of Ral activation-related mRNA.
Project description:To further development of our lncRNA and mRNA expression approach to pancreatic ductal adenocarcinoma(PDAC), we have employed lncRNA and mRNA microarray expression profiling as a discovery platform to identify lncRNA and mRNA expression in pancreatic ductal adenocarcinoma.Human pancreatic ductal adenocarcinoma tissues and normal pancreatic tissues from PDAC donors and other duodenum diseases donors. analyze mRNA and lncRNA expression in pancreatic ductal adenocarcinoma (PDAC) by microarray platform
Project description:The aim of this project is to identify and characterize circular RNAs with critical roles in pancreatic ductal adenocarcinoma (PDAC).
Project description:Glucose metabolism makes contributions to the development of pancreatic ductal adenocarcinoma (PDAC). Meanwhile, circular RNAs, a subset of noncoding RNAs, plays an important role in glucose metabolism and cancer progression. Analysis of low-glucose-treated and normal-glucose-treated MIA PaCa-2 cells from 6 samples (3 samples each group) was conducted. Results indicate insight into molecular signature of the pathogenesis of PDAC in abberant glucose metabolism.
