Mouse Lung Response to Stainless Steel and Mild Steel Welding Fume. Mus musculus

A/J mice are genetically predisposed to spontaneous and/or chemically-induced lung tumors while C57BL/6J (B6) mice are resistant. This genetic disparity provides a unique scenario to identify molecular mechanisms associated with the lung response to welding fume at the transcriptome level. Overall design: Four mice per group were exposed four times by pharyngeal aspiration to 5mg/kg mild steel (MS) fume, stainless steel (SS) fume, or saline vehicle and were necropsied 28 days and 16 weeks after the last exposure. Whole lung microarray using Illumina Mouse Ref-8 version 1.1 expression beadchips was done.
