Gene expression in old and chemotherapy. a Heatmap of pair-wise analysis of differential (limma-based general linear model) gene expression (log2 (1 + x) counts per million); YvsO and YvsC. The corresponding max and min values are as follows; YvsO (0, 12.96), YvsC (0, 13.52). b IPA core-pathway analysis; no color = no activity detected; grey color = direction of activity cannot be predicted; orange color = up-regulated activity. Color intensity reflects level of expression
