Project description:Expression analysis of 36 pancreatic ductal adenocarcinoma tumors and matching normal pancreatic tissue samples from pancreatic cancer patients of the Clinical Institute Fundeni (ICF) using Affymetrix U133 Plus 2.0 whole-genome chips.
Project description:In this study, we screened 457 tissue samples of patients with various pancreatic neoplasms by transcriptional profiling. In the analysis, we focused particularly on the expression variations detected for genes that are associated with autophagy in pancreatic ductal adenocarcinoma (PDAC) and cystic tumors as well as the tumors macro-environment. The files contain both raw and normalized data.
Project description:Expression analysis of 36 pancreatic ductal adenocarcinoma tumors and matching normal pancreatic tissue samples from pancreatic cancer patients of the Clinical Institute Fundeni (ICF) using Affymetrix U133 Plus 2.0 whole-genome chips. Pairs of normal and tumor tissue samples were obtained at the time of surgery from resected pancreas of 36 pancreatic cancer patients. Gene expression was analyzed on Affymetrix U133 plus 2.0 whole genome microarrays. For three of the 36 normal-tumor sample pairs we carried out replicate microarray hybridizations in order to gauge the technical measurement errors. We thus performed 78 genechip hybridizations in total. A patient sample pair was excluded from further analysis since one of the samples did not meet the quality controls. The microarray data was subsequently normalized using the RMA algorithm.
Project description:The goal of the experiment was to explore the differences in the proteomic landscape of pancreatic cancer tissues collected by the Rapid Autopsy Program at UNMC. We hypothesized the proteomic profile can reflect some of the clinical features observed in the patient, and such information can be used for the diagnosis of the disease, or assisting in the selection of treatment options in a clinical setting. The liver metastases tissue collected from 59 pancreatic cancer patients were used to explore the proteomic landscape. 56 of these patients were diagnosed with pancreatic ductal adenocarcinoma (PDAC) and 3 of them had pancreatic neuroendocrine tumors (PanNET).
Project description:Genome wide DNA methylation profiles of human pancreatic tissue. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 485,000 CpGs. Dataset includes in total 24 pancreatic tissue samples,12 samples of patients with ductal adenocarcinoma and 12 samples of healthy person. Bisulphite converted DNA from the 24 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip.

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: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:Transcriptomic analysis of cancer samples helps to identify the mechanism and molecular markers of cancer. However, transcriptomic analyses of pancreatic ductal adenocarcinoma from the Japanese population are lacking. We performed RNA sequencing of flesh or frozen pancreatic ductal adenocarcinoma tissues and adjacent normal pancreatic tissue from 12 Japanese patients to identify genes critical for the clinical pathology of pancreatic cancer among the Japanese population.
