Global gene expression analysis of fresh-frozen, furan-exposed mouse liver using RNA-seq [polyA enrichment]
Furan is a mouse and rat hepatocarcinogen. We sought to determine if furan-induced gene expression changes could be detected in paired fresh-frozen and formalin-fixed paraffin embedded (FFPE) samples using RNA-seq (polyA-enrichment protocol).  All samples in this study (fresh-frozen, 18 hours in formalin, 3 weeks in formalin) were also examined using one- and two-colour microarrays and RNA-seq (ribo-depletion protocol) in order to determine the effect of the technology on gene expression profiles. Overall design: In this study we examined the transcriptional response in liver tissue of female B6C3F1 mice exposed to furan for 3 weeks to 8 mg/kg bw furan (or vehicle control) and sacrificed four hours after the final exposure.  Each dose group had 4 biological replicates. There were a total of 24 samples included in the final analysis of the polyA enrichment RNA-seq experiment.
