    • 本研究試圖去分析現有大量來自不同人類組織的基因表現資料，去尋找那些具有規則性表現或是會同時表現於某幾種組織裡面的基因，這些基因可能具有某些生物上或是藥理學上的關聯性。在本文中，我們提出兩種不同的方式去分析那些表現在不同人類組織中的大量基因之間的關聯性，這些會特別地或是規則地表現在某些特定組織裡的關係透露出這些基因可能具有某些調控上的意義或者是屬於同一個反應路徑和訊號傳導流程的其中一環。

    The study attempts to analyze a large number of human genome transcription products from diverse tissues and to discover genes that are co-expressed in some different tissues. Those genes may be of potential biological or pharmaceutical relevance. We proposed two approaches to discover the correlations of gene expression by analyzing multiple expression profiles of different human tissues. The correlations of gene expression reveal that genes are specifically or regularly expressed in particular tissues simultaneously. Besides, the correlations of gene expression can be used to identify the relationships of genes which are potential to be co-regulated, involving in the same biochemical pathway or signal transduction process.
