Global gene expression analysis of fresh-frozen, furan-exposed mouse liver using RNA-seq [polyA enrichment]

(Submitter supplied) 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.

Global gene expression analysis of fresh-frozen, furan-exposed mouse liver using one-colour Agilent microarrays

(Submitter supplied) 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 one-colour microarrays.

Global gene expression analysis of formalin-fixed paraffin-embedded (FFPE), furan-exposed mouse liver using one-colour Agilent microarrays

(Submitter supplied) 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 one-colour microarrays. To determine the effect of time-in-formalin on gene expression signatures we performed microarray analysis of livers that were fixed in formalin for 18 hours or 3 weeks. All samples (fresh-frozen, 18 hours in formalin, 3 weeks in formalin) were also examined using two-colour microarrays and RNA-seq (ribo-depletion and polyA-enrichment protocols) in order to determine the effect of the technology on gene expression profiles.

Preparation of archival formalin-fixed paraffin-embedded mouse liver samples for use with the Agilent gene expression microarray platform

(Submitter supplied) For decades, formalin-fixing and paraffin embedding (FFPE) has been routinely used to preserve tissue samples for histological analysis. Global gene expression analysis of these archival tissues has the potential to greatly advance research attempting to link perturbations in molecular pathways to disease outcome. We investigated 16-year-old FFPE mouse liver samples treated with phenobarbital and created a protocol for their analysis using Agilent gene expression arrays. more...

Gene profiling using archival formalin-fixed paraffin-embedded breast cancer specimens can generate informative microarray data: A comparison with matched fresh fine needle aspiration biopsy samples (FNA samples)

(Submitter supplied) The Formalin-Fixed Paraffin-Embedded (FFPE) samples on selected breast cancer subtypes (ER+/Her2-, ER+/Her2+, ER-/Her2+, and ER-/Her2-) and their paired fresh fine needle aspirated biopsies (FNA) were investigated. The cases represented different subtypes of breast cancers based on their clinical receptors ER (E) and Her2 (H) status to demonstrate the ability of gene profiles to differentiate these tumors. more...

Gene-expression profiles of archived section of formalin-fixed paraffin-embedded (AS-FFPE) liver tissues from hepatocellular carcinoma patients

(Submitter supplied) Background and Aims Formalin-fixed, paraffin-embedded (FFPE) tissue is the most commonly available form of archived clinical specimens, which are often stored as thin sections on glass slides. RNA isolated from such archived section (AS) of FFPE tissue is more degraded compared to freshly cut (FC) FFPE section because of prolonged air exposure. In this study, we evaluated performance of transcriptome profiling-based disease classification in AS-FFPE tissue. more...
