Gene expression data from 16-month and 3-month old male rats, with three different levels of activity over the life span: sedentary, twice weekly physical activity, regular running wheel exercise.

We used microarrays to detail global gene expression underlying select health-related phenotypes and identified differentially expressed genes among the three groups.本研究通过基因芯片（microarrays）技术，详细解析了与选定健康相关表型相关的全局基因表达谱，并在三个组别中鉴定出差异表达基因。
