Hierarchical clustering of differentially expressed genes related to the major functions of AMs. Genes involved in immune response, inflammation, phagocytosis, and cell death were analyzed. Each lane represents the expression profile of AMs from one rat. For each panel, the first four lanes show the expression profiles of AMs from the four Dex-Pc rats compared to that of Dex rats, the middle four lanes display those of the four Dex rats compared to that of Normal rats, and the remaining four lanes represent those of the four Dex-Pc rats compared to that of Normal rats. Red and blue colors indicate high and low expression levels, respectively. Gray color indicates no change in expression levels.
