Project description:TGF-beta treatment of Panc-1 pancreatic adenocarcinoma cell line on Affymetrix HG_U133_plus_2 arrays; triplicate experiments. The goal of the experiment is to profile temporal gene expression changes during TGF-beta-induced epithelial-mesenchymal transition (EMT). During EMT cancer cells lose their epithelial specifc proteins and gain mesenchymal proteins to acquire migratory and invasive phenotype essential for metastasis. Human Panc-1 pancreatic adenocarcinoma cell line was treated with 5 ng/mL TGF-beta for 48 h to induce EMT. The experiment was repeated 3 times. Samples were assayed using Affymetrix HG_U133_plus_2 arrays with 54675 probe-sets, using standard techniques.

Project description:Gemcitabine has been a first-line therapeutic agent for pancreatic ductal adenocarcinoma (PDAC) pancreatic cancer; however, acquisition of resistance to gemcitabine remains a major challenge. We analyzed miRNAs expression profiles by array-based miRNAs analysis between gemcitabine–resistant (PANC-1/GEM) and parental PANC-1 cells.

Project description:cGMP is well-known secound messanger involved in vascular homeostasis. However little is known the effect of cGMP inducer on mRNA expression in cancer cells. We performed microarrays to revealed the transcriptional change of a human pancreatic ductal adenocarcinoma (PDCA) cell line (Panc -1) to cGMP inducer Bay41-2272 in order to provide insight into impact of cGMP induction on Panc-1 cells. Panc-1 Human PDCA cells were treated with vehicle (DMSO) or 5 μM Bay41-2272 for 48 h and total RNA was extracted by using TRIzol Reagent. The microarray analysis was conducted on the Panc-1 cells expressing by using Agilent Microarray.

Project description:Little is known about the role of FOXO3 and PDHA1 in PDAC. We performed microarrays to revealed the transcriptional change of a human pancreatic ductal adenocarcinoma (PDCA) cell line (Panc -1) to scr-siRNA, FOXO3-siRNA and PDHA1-siRNA in order to provide insight into the role of PDHA1 and FOXO3 in Panc-1 cells. Panc-1 Human PDCA cells were treated with scr-siRNA, FOXO3-siRNA and PDHA1-siRNA for 48 h and total RNA was extracted by using TRIzol Reagent. The microarray analysis was conducted on the Panc-1 cells expressing by using Agilent Microarray.

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 PANC-1, a mutant p53 human pancreatic adenocarcinoma cell line, were established. MicroRNA screening was investigated by microarray. Gemcitabine-resistant PANC-1 (PANC-1-GR) cell clones were produced by exposing the parental cells to repeated pulsatile gemcitabine treatment over 3 days with constant sublethal concentrations followed by recovery-periods with agent-free medium until the cells recovered exponentially. Parental PANC-1 cells were treated with 0.4µM gemcitabine cycles for approximately 9 months. Affymetrix GeneChip miRNA microarrays (Affymetrix UK Ltd., High Wycombe, UK) were performed in parental and chemoresistant PANC-1 cells after 17 chemotherapy cycles using the manufacturers´ protocols. The samples were prepared from 1µg of total-RNA in accordance with the Affymetrix FlashTag Biotin HSR RNA Labeling Kit. The targets were hybridized overnight to Affymetrix GeneChip miRNA arrays. Following hybridization, the arrays were washed and stained using the Affymetrix GeneChip Fluidics Station 450 and scanned using the Affymetrix GeneChip Scanner 3000 7G. Microarray data quality was checked as recommended by the manufacturer and by the quality metrics in the Partek Genomics Suite software (Partek Inc., St. Louis, MO).

Project description:Time Course of TGF-beta treatment of A549 lung adenocarcinoma cell line on Affymetrix HG_U133_plus_2 arrays; triplicate experiments. The goal of the experiment is to profile temporal gene expression changes during TGF-beta-induced epithelial-mesenchymal transition (EMT). During EMT cancer cells loose their epithelial specifc proteins and gain mesenchymal proteins to acquire migratory and invasive phenotype essential for metastasis. Human A549 lung adenocarcinoma cell line was treated with 5 ng/mL TGF-beta for 0, 0.5, 1, 2, 4, 8, 16, 24, and 72 h to induce EMT. The experiment was repeated 3 times. Samples were assayed using Affymetrix HG_U133_plus_2 arrays with 54675 probe-sets, using standard techniques. We provide the raw .CEL files and a supplementary Excel spreadsheet with log-transformed data and selected results from a statistical analysis. Experiment Overall Design: Human A549 lung adenocarcinoma cell line was treated with 5 ng/mL TGF-beta for 0, 0.5, 1, 2, 4, 8, 16, 24, and 72 h. The experiment was repeated 3 times. Samples were assayed using Affymetrix HG_U133_plus_2 arrays with 54675 probe-sets, using standard techniques. The 2 h sample of the third experiment was not run on an array due to poor RNA, so that only 26 arrays were run.

Project description:To explore malignant phenotype related genes in Panc-1-CTC, we performed gene expression array analysis with Panc-1-CTC and Panc-1-Parent (Panc-1-P). As a result, TGFBI upregulation emerged as highly malignant feature for pancreatic ductal adenocarcinoma. Identification of malignant phenotype related genes in pancreatic ductal adenocarcinoma
