Project description:Transcription profiling of human A549 lung cancer cells treated with actinomycin D and sapphyrin PCI-2050 a new class of tumor-selective inhibitors of gene expression.
Project description:The goal of this project was to characterize changes in gene expression in response to the anti-cancer agent sapphyrin PCI-2050. Cultured A549 human lung cancer cells were treated with sapphyrin PCI-2050 or actinomycin D.
Project description:The goal of this project was to characterize changes in gene expression in response to the anti-cancer agent sapphyrin PCI-2050. Cultured A549 human lung cancer cells were treated with sapphyrin PCI-2050 or actinomycin D, a known transcripitonal inhibitor. The gene expression profiles of drug-treated and control A549 cultures were determined using Human Genome U133 Plus 2.0 Arrays (Affymetrix, Santa Clara, CA). Further details are provided in our published manuscript: <http://www.molecular-cancer.com/content/6/1/9>. Keywords: responses to treatments with anti-cancer agents

Project description:We have shown that water solubilized versions of a zinc ionophore increase intracellular concentrations of free zinc and have antiproliferative activity in exponential phase A549 lung cancer cultures. The gene expression profiles of A549 lung cancer cultures treated with the lead compound PCI-5002 reveal the activation of stress response pathways. Medium supplementation with zinc (25 μM) led to activation of additional oxidative stress response as well as apoptotic pathways. We propose that the pharmacologic delivery of zinc to tumors using water solubilized ionophores is a potential approach to cancer therapy. Keywords: Dose response
