Transcription profiling of human GRE specific DNA-binding polyamide effect on dexamethasone-stimulated lung adenocarcinoma cell line

ABSTRACT: Analysis of dexamethasone-stimulated A549 lung adenocarcinoma epithelial cells treated with a glucocorticoid response (GR) element (GRE) specific DNA binding polyamide. Polyamide designed to target the sequence 5'-WGWWCW-3' and disrupt GR-mediated gene expression. Effects of the GR antagonist mifepristone also examined. Experiment Overall Design: A549 cells were treated with compounds for 48 hours before RNA extraction and hybridization on Affymetrix microarrays.

Transcription profiling of human A549 lung adenocarcinoma cell line time Course of TGF-beta treatment

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.

Oligonucleotide DNA microarray profiling identifies novel genes involved in lung adenocarcinoma

Project description:The purpose of this study was to find novel gene(s) involved in the development of lung adenocarcinomas (AD) using an oligonucleotide based DNA microarray platform with a selected set of genes from Human Apoptosis Subset v2.0 and Human Cancer Subset v3.0 (Operon). In order to identify possible novel genes involved in the development of lung ADs we analysed the expression profile of 12 lung adenocarcinomas. We used dual color approach. Tumour tissue was labeled with Cy5 and corresponding normal tissue was labeled with Cy3. Each array contained at least 4 replicate spots for each gene analysed. Gene expression was obtained by calculating median from replicate spots.

Sequence-specific DNA cleavage mediated by bipyridine polyamide conjugates.

Project description:The design of molecules that damage a selected DNA sequence provides a formidable opportunity for basic and applied biology. For example, such molecules offer new prospects for controlled manipulation of the genome. The conjugation of DNA-code reading molecules such as polyamides to reagents that induce DNA damages provides an approach to reach this goal. In this work, we showed that a bipyridine conjugate of polyamides was able to induce sequence-specific DNA breaks in cells. We synthesized compounds based on two polyamide parts linked to bipyridine at different positions. Bipyridine conjugates of polyamides were found to have a high affinity for the DNA target and one of them produced a specific and high-yield cleavage in vitro and in cultured cells. The bipyridine conjugate studied here, also presents cell penetrating properties since it is active when directly added to cell culture medium. Harnessing DNA damaging molecules such as bipyridine to predetermined genomic sites, as achieved here, provides an attractive strategy for targeted genome modification and DNA repair studies.
