研究興趣

　　生物分子影像 (molecular imaging) 近年來已成為一新興的研究領域，藉由核醫藥物或報導基因等方式將活體內的生理生化反應，非侵入且即時反應活體內情形，藉此可了解不同細胞，如癌細胞與周遭腫瘤微環境的交互作用;抑或可用於評估藥物是否適用於病人，達到個人化的精準醫療，提高有效治療。

    放射治療為目前癌症治療的主力之一，但對於具輻射抗性或已轉移之癌細胞效果不彰。因此，如何增進放射治療之療效為一重要課題。脂肪酸合成酶 (Fatty acid synthase, FASN) 為體內脂肪酸合成重要酵素，脂肪酸為重要生物分子，與細胞膜組成激素合成皆有密切關係。研究發現，與正常細胞不同，多數癌細胞大量表現FASN以供應足夠細胞組成原料及能量來源供癌細胞快速增生。然而，FASN表現是否影響細胞之輻射抗性仍未清楚，是否可藉調節FASN表現，達到增進放射治療效果亦尚須探討。

         目前放射治療療效評估係利用CT或MRI判斷腫瘤體積是否變小，但單就體積變化並無法精確判斷治療效果，如腫瘤體積不變，但腫瘤內部凋亡或壞死時。此外核醫常用¹⁸F-FDG PET雖可利用癌細胞較正常細胞有更多的葡萄糖攝取之特性做為癌症偵測工具; 但當癌細胞及放射治療引起之發炎反應 (Radiation-induced inflammation) 並存時，¹⁸F-FDG影像便無法準確反映殘存的癌細胞與治療前之差異。因此若能發展一可反映放射治療療效之工具，將對放射治療的臨床應用有極大助益。

　　本實驗室主要研究興趣於探討調控FASN分子表現是否可增進放射治療效果，透過生物分子影像技術於動物體內追蹤放射治療後FASN 為主的基因轉殖細胞FASN表現的變化反之亦利用分子基因的方式使癌細胞表現不同量的FASN測試所形成之腫瘤，其輻射敏感度是否不同，此外，也將探討FASN 與其他分子表現的關係。此研究結果將有助於放射治療療效，並提供相關機制及新興療法之可能性。實驗室另一研究主題為，利用可被放射線活化基因為核心建立帶有報導基因之載體，選擇具專一性且可利用臨床常規檢查之報導基因，發展出可評估放射治療預後的分子診斷平台。
