Project description:To study the molecular signatures of mRNAs and miRNAs which can potentially act as a prognostic biomarkers in pancreatobiliary and intestinal types of periampullary adenocarcinomas Total RNA was isolated from 10 x 20 µm sections of 83 fresh frozen tumor samples for miRNA expression profiling. A total of 51 PDAC, 8 bile duct adenocarcinoma, 8 ampulla of pancreatobiliary tye, 7 ampulla of intestinal type, 9 duodenum sample and 6 adjacent normal samples were used. These samples were analysed by microarray analysis using the 60K agilent platform. The expression profiles was RMA normalized for miRNA expression data. Filtering of controls, unannotated genes and low expressed probes was done.

A total of 49 PDAC, 8 bile duct adenocarcinoma, 8 ampulla of pancreatobiliary tye, 7 ampulla of intestinal type, 9 duodenum sample and 12 adjacent normal samples were used. These samples were analysed by microarray analysis using the 60K agilent platform. The expression profiles were background corrected and quantile normalized for mRNA. Filtering of controls, unannotated genes and low expressed probes was done.
Project description:Adenocarcinomas of the ampulla of Vater are classified as biliary cancers, though the exact epithelium of origin for these cancers is not known. We sought to molecularly classify ampullary adenocarcinomas in comparison to known adenocarcinomas of the pancreas, extrahepatic bile duct, and duodenum by gene expression analysis. We analyzed 32 fresh-frozen resected, untreated periampullary adenocarcinomas (8 pancreatic, 2 extrahepatic biliary, 8 duodenal, and 14 ampullary) using the Affymetrix U133 Plus 2.0 genome array.

Project description:To identify aberrantly expressed long intergenic noncoding RNAs (lincRNAs) in bladder cancer tissues compared with normal adjacent tissues, we have employed microarray expression profiling as a discovery platform to identify lincRNAs that may play important roles in bladder cancer origin and progression. Samples of fresh frozen cancer tissues, together with normal adjacent tissues (3 cm away from the tumor), were obtained during surgical resection, and total RNA was extracted for microarray analysis. Two pairs of fresh frozen bladder cancer tissues and corresponding normal adjacent tissues were used in the microarray analysis.
