研究興趣

        本研究團隊進行基礎與應用性研究，主題包括為： 遺傳物質修補功能、染色體結構完整性、及致癌基因誘發細胞病變機轉。運用細胞株及動物個體研究模式，針對乳癌及肺癌形成機轉進行研究。 
        我們早期研究發現自體免疫蛋白Ku及DNA激脢蛋白(DNA-PKcs)共同參與雙股DNA斷裂修補工作。進一步探討發現Ku及DNA-PKcs在穩定基因體末端架構上伴演重要角色。Ku及DNA-PKcs基因缺失之轉殖鼠細胞呈現染色體末端異常結合形態、縮短染色體長度、加速細胞老化過程、且該動物體易罹患腫瘤病變。實驗證明Ku與染色體末端結合蛋白TRF1具功能性密切交互作用，藉此TRF1/Ku蛋白質體間直接結合，藉以調節染色體末端結構穩定。目前我們正積極從事基因體修補能力及染色體結構整合層面，探索正常細胞的基因體監控調節如何被擾亂導致轉型為癌細胞。
        一方面我們的研究主題針對致癌基因作用機制。新致癌基因MCT-1蛋白質過量表達導致細胞快速增殖、擾亂基因體監視激脢訊息傳導途徑、及持續過度活化DNA修補蛋白脢活性。我們已明顯觀測到MCT-1蛋白嚴重造成多條染色質錯誤連結、遺傳物質轉移、及異常複製現象。增加MCT-1在肺細胞或乳腺細胞表現量，我們可檢測細胞轉化能力、抗癌試劑抗藥性、及基因體結構破壞程度，來剖析基因變異及細胞生理功能惡化機轉。針對抑制MCT-1在癌細胞表現活性，是否可減緩癌細胞增殖能力、提升癌細胞對藥物化學及放射物理療法感受度，預期評估MCT-1基因調控在醫療運用價質。MCT-1基因轉殖鼠技術配合生物化學研究及組織切片分析，將輔助證明體外細胞實驗數據結果。綜合上述之研究成果將益助於早期診斷、治療及預防癌細胞轉移惡化之可能性。
        隨著「後基因體時期」(post-genomic era) 時代來臨，對於基因之結構與功能的瞭解非常迅速，使得我們能據以觀察分析，找出在疾病演生時呈現異常表現的基因。這些基因資訊不僅能顯示疾病的分子遺傳機轉，也發展診斷及治療方法的重要標的。
