Expression analysis of liver tissues from LPS or LPS/GalN treated mice. Mus musculus

Investigation of whole genome gene expression level changes in the liver tissue from LPS/GalN treated mice, compared to LPS treated mice Treatment of mice with LPS and the liver-specific transcriptional inhibitor D-(+)-galactosamine (GalN) induces fatal hepatitis, which is mediated by TNFα and characterized by massive hepatic apoptosis. Previous studies suggest that GalN increases the sensitivity to LPS/TNFα probably by blocking the transcription of protective factors, but the identity of most of these factors is still unclear. This analysis is performed to indentify these protective factors. Overall design: A six chip study using total RNA extracted from liver tissues of three separate LPS treated mice and three separate LPS/GalN treated mice. Each chip measures the expression level of 44,170 genes from C57 BL/6 mice with three 60-mer probe pairs per gene.
