Mouse prostate strain-associated gene expression and analysis in human prostate tissues: FVB/N and C57BL/6. (a) Genes differentially expressed in prostates of FVB/N and C57BL/6 strains. Heat map colors reflect fold ratio values between sample and reference pool. Columns 1-4 represent biological replicates for each strain. Rows represent individual genes. Values shown in red are relatively larger than the overall mean; values shown in green are relatively smaller than the overall mean. (b) Transcript abundance levels in benign human prostate tissues associated with high grade (7-10) or low grade (≤6) adenocarcinomas for each gene determined to be altered in mouse strain comparisons where a corresponding ortholog was identified. Genes depected in (a) and (b) are in identical order. Black box (b) and text (a) represent genes with significant differential expression in the human datasets altered in the expected orientation. Gray box (b) and text (a) represent genes with significant differential expression in the human datasets altered in the opposite orientation. (c-e) Transcript alterations for selected genes in benign tissue samples associating with high (Gleason 7-10) and low (Gleason ≤6) prostate cancers. Plots represent the 95% confidence intervals of log₂ expression ratios of tissues samples relative to a cell line reference.
