Expression data from liver of young and old rats fed on different dietary fat sources, namely virgin olive, sunflower or fish oils

We used microarrays to detail the changes in gene expression provides by feeding lifelong on different dietary fat sources, and identified distinct classes of up and down-regulated genes during aging under different dietary conditions.本研究采用基因芯片（microarray）技术，详细解析了终身摄入不同膳食脂肪来源所诱导的基因表达变化，并鉴定出不同膳食条件下衰老过程中不同类别的上调与下调基因。
