Project description:We sought to determine whether certain miRNAs could serve as a biomarker for the prognosis of pancreatic ductal adenocarcinoma (PDAC) and uncover the uncharacterized miRNAs function in the pancreatic carcinogenesis
Project description:Perineural invasion (PNI) is a prominent characteristic of pancreatic ductal adenocarcinoma (PDAC) and indicates poor prognosis. The invasion of the surrounding nerves by pancreatic cancer cells not only provides route for metastasis but also contributes to neural remodeling and changes in the neuronal milieu that can profoundly influenced the microenvironment of pancreatic cancer. To investigate the downstream molecules associated with PNI, the experiment analyzed mRNA expression of 50 pairs of pancreatic ductal adenocarcinoma tissue and paired adjacent non-tumor tissue, among which 28 pairs of cases diagnosed with PNI by experienced pathologist. Results provide new insight into molecular basis for the influence of PNI on the microenvironment of pancreatic cancer.
Project description:Serous (cystic) neoplasm (SCN) of the pancreas is usually benign cystic neoplasm and has unique biological characteristics that are different from those found in the normal pancreatic tissue or pancreatic ductal adenocarcinoma (PDAC) tissue. In order to investigate molecular mechanisms involved in the unique biological phenotypes of, we compared gene expression profiles of SCN tissues with those of normal pancreatic tissues or those of PDAC tissues.
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
