Microarray analysis was used to characterize the changes in gene expression profiles of AsPC-1 and COLO-357 upon PD-0332991 incubation AsPC-1 and COLO-357 cells were treated in the absence or presence of 5 µM PD-0332991 for 24 h and 72 h. Each expreimental condition had biological triplicates. Twenty-four samples were analyzed in total.
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:This microarray is an analysis of differentially expressed genes in three pancreatic ductal adenocarcinoma cell lines treated with LXR-agonist GW 3965. We first report that GW 3965 has antiproliferative effects in three PDAC cell lines. This microarray was designed to identify key mechanisms of the antiproliferative effect of LXR agonists within pancreatic cancer cell lines.
Project description:Protein arginine methylation has been established an essential protein modification regulating cancer initiation and progression, but its implications in PDAC (Pancreatic ductal adenocarcinoma) still remains poorly elucidated. In this study, we characterized ADMA (asymmetric dimethylarginine)-bearing peptides in human pancreatic ductal epithelium cell line HPDE6c7 and PDAC cell line PANC-1 by a label-free quantitative proteomics combined with affinity purification.
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.

This microarray was designed to identify key mechanisms of the antiproliferative effect of LXR agonists within pancreatic cancer cell lines. Total RNA obtained from BxPC-3, MIA-PaCa-2, and PANC-1 pancreatic cancer cells grown in culture treated GW 3965 or ethanol (vehicle control) for 72 hours.

Project description:No reliable predictors of susceptibility to gemcitabine chemotherapy exist in pancreatic ductal adenocarcinoma. MicroRNAs (miR) are epigenetic gene regulators with tumorsuppressive or oncogenic roles in various carcinomas. This study assesses chemoresistant PDAC for its specific miR expression pattern. Gemcitabine-resistant variants of two mutant p53 human pancreatic adenocarcinoma cell lines were established. MicroRNA screening was investigated by microarray.
