Gene expression analysis between the pancreatic tissues of Pdx1-cre;Kras LSL-G12D and Pdx-cre;KrasLSL-G12D;IKK2/beta F/F mice

Project description:Constitutive Kras and NF-kB activation is identified as signature alterations in human pancreatic ductal adenocarcinoma (PDAC). Here, we report that pancreas-targeted IKK2/beta inactivation inhibited NF-kB activation and completely suppressed PDAC development. Our findings demonstrated that NF-kB is required for development of pancreatic ductal adenocarcinoma that was initiated by Kras activation. Pancreatic tissue from 4 groups of mice were used in this project: (1) the pancreas normal appearance of Pdx1-cre;KrasLSL-G12D;IKK2/beta mice, (2) the normal pancreas of Pdx1-cre;KrasLSL-G12D mice, (3) the pancreatic lesion of pancreatic intraepithelial neoplasia (PanIN) of Pdx1-cre;KrasLSL-G12D mice, and (4) the pancreatic lesion of PDAC of Pdx1-cre;KrasLSL-G12D mice. Each group included three mice. RNA samples from mouse pancreas were hybridized on GeneChip Mouse Gene 1.0 ST arrays (Affymetrix). Group (1) and group (2) were compared, and group (2), group (3) and group (4) were compared.

S100P is a metastasis-associated gene that facilitates transendothelial migration of pancreatic cancer cells [HG-U133B]

Project description:Pancreatic cancer is a devastating disease with both local invasion and distant metastasis. Identifying the genes expressed in liver metastases and signatures of metastatic progression would therefore be of particular importance as they could aid in both recurrence prediction as well as representing novel therapeutic targets. Keywords: Gene expression profiling We have performed microarray gene expression analysis of normal pancreas, primary pancreatic ductal adenocarcinoma (PDAC), normal liver and pancreatic liver metastases to identify potential therapeutic targets.

Profiling of Kallikrein Proteases and Global Proteome Biology of PDAC, Chronic Pancreatitis and Normal Pancreas

Project description:Cell conditioned medium from human pancreatic cancer cell lines MiaPaCa-2, AsPC-1, primary pancreatic cell lines as well as human FFPE tissue samples from pancreatic ductal adenocarcinoma (PDAC), chronic pancreatitis (CP), ampullary cancer, non-malignant adjacent pancreas and normal pancreas were analyzed via targeted (SRM, PRM) and/or explorative (DIA) mass spectrometry.

Gene Expression of Serous Cystic Neoplasm of the Pancreas Tissues

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.

Methylated DNA immunoprecipitation coupled with NimbleGen's array to identify methylated genes in pancreatic ductal adenocarcinoma

Project description:Pancreatic ductal adenocarcinoma (PDAC) is a highly invasive cancer with a poor prognosis. Using methylated DNA immunoprecipitation (MeDIP)-chip analysis, we found that 161 genes that were specifically hypermethylated in PANC-1 cells. Among them, miR-615-5p was hypermethylated in its putative promoter region, which silenced its expression in PDAC cell lines. Comparison between PANC-1 cell lines and normal pancreas tissue
