Expression data from TGF-beta treated Panc-1 pancreatic adenocarcinoma cell line

ABSTRACT: 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. Human Panc-1 pancreatic adenocarcinoma cell line was treated with 5 ng/mL TGF-beta for 48 h. The experiment was repeated 3 times. Samples were assayed using Affymetrix HG_U133_plus_2 arrays with 54675 probe-sets, using standard techniques.

Expression data of human lung adenocarcinoma cell line H441 treated with TTF-1/NKX2-1 siRNA and TGF-beta

Project description:We determined and analyzed the effect of TTF-1/NKX2-1 on Smad3/Smad4 binding sites by ChIP-sequencing. We used expression microarrays to evaluate the effect of TTF-1/NKX2-1 siRNA on TGF-beta-induced gene expressions. H441 cells were transfected with siRNAs and treated with TGF-beta for RNA extraction and hybridization on Affymetrix microarrays. This submission represents transcriptome component of study.

Expression analysis of human pancreatic cancer cell lines (Capan-1, Panc-1, Panc-1+ve and Panc-1-ve) and pancreatic ductal cell line (HPDE)

Project description:Analysis of differentially expressing genes in whole genome wide analysis of aptamer SQ2 positive cells (Capan-1, Panc-1, Panc-1+ve) and SQ2 negative cells (Panc-1-ve and HPDE) Panc-1 +ve and Panc-1-ve cell lines were generated from Panc-1 cell line based upon its hetergenous binding to aptamer SQ2. Detailed procedure of generation of these cell lines are described in Pooja Dua, Hye Suk Kang, Seung-Mo Hong, Ming-Sound Tsao, Soyoun Kim, and Dong-ki Lee. 2012 Alkaline Phosphatase ALPPL2 is a novel pancreatic carcinoma-associated protein. Cancer Research A five chip study using total RNA recovered from Capan-1, Panc-1, Panc-1+ve, Panc-1-ve and HPDE cells. Each chip measures 45,033 genes with three 60 mer probe pairs per target.

Pancreatic Adenocarcinoma Therapeutics Targeting RTK and TGF Beta Receptor.

Project description:Despite the improved overall survival rates in most cancers, pancreatic cancer remains one of the deadliest cancers in this decade. The rigid microenvironment, which majorly comprises cancer-associated fibroblasts (CAFs), plays an important role in the obstruction of pancreatic cancer therapy. To overcome this predicament, the signaling of receptor tyrosine kinases (RTKs) and TGF beta receptor (TGFβR) in both pancreatic cancer cell and supporting CAF should be considered as the therapeutic target. The activation of receptors has been reported to be aberrant to cell cycle regulation, and signal transduction pathways, such as growth-factor induced proliferation, and can also influence the apoptotic sensitivity of tumor cells. In this article, the regulation of RTKs/TGFβR between pancreatic ductal adenocarcinoma (PDAC) and CAFs, as well as the RTKs/TGFβR inhibitor-based clinical trials on pancreatic cancer are reviewed.

Metabolic characterization of invaded cells of the pancreatic cancer cell line, PANC-1.

Project description:We previously reported that about 0.4% of cells in the cultured human pancreatic cancer cell line, PANC-1, can invade matrigel during the transwell invasion assay, suggesting that these invaded PANC-1 cells may have specific characteristics to keep their invasive potential. To identify the metabolic characterization specific in the invaded PANC-1 cells, metabolome analysis of the invaded PANC-1 compared with the whole cultured PANC-1 was performed using CE-TOFMS, and concentrations of 110 metabolites were measured. In contrast to the whole cultured cells, the invaded PANC-1 was characterized as a population with reduced levels of amino acids and TCA cycle intermediates, and decreased and increased intermediates in glycolysis and nucleic acid metabolism. In particular, the ratio of both adenosine and guanosine energy charge was reduced in the invaded cells, revealing that the consumption of ATP and GTP was high in the invaded cells, and thus suggesting that ATP- or GTP-generating pathways are stimulated. In addition, the GSH/GSSG ratio was low in the invaded cells, but these cells had a higher surviving fraction after exposure to hydrogen peroxide. Thus, the invaded cells were the population resistant to oxidative stress. Furthermore, reduction in intracellular GSH content inhibited PANC-1 invasiveness, indicated that GSH has an important role in PANC-1 invasiveness. Overall, we propose the invaded cells have several unique metabolic profiles.

Expression data of the human hepatoblastoma cell line HepG2 treated with TGF-beta

Project description:Smad2/3 are transcription factors that engage in TGF-beta-induced transcription. We determined and analyzed HepG2 and Hep3B-specific Smad2/3 binding sites by ChIP-chip. We used expression microarrays to compare the Smad2/3 and HNF4alpha binding sites identified by ChIP-chip or ChIP-seq, respectively, to TGF-beta-induced gene expressions.
