研究方向研究室特色

1.癌症抗藥機制與凋亡Modulating chemotherapeutic resistance and apoptosis):
本研究室主要目標是探討癌症之化學及輻射治療失效的分子機制及改進癌療的研發。運用基因科技修改DNA修補及細胞凋亡 (modulation of DNA repair & apoptosis) 可以克服癌細胞的抗藥、抗輻射現象。利用蛋白生化及基因選殖技術,我們發現數種受基因毒損壞DNA 的辨識及修補蛋白,譬如HMG (high-mobility group)DDB1 DDB2 蛋白,其活性在細胞內可明顯地修飾藥物反應。此外,我們更進一步運用基因晶片 (DNA microarray) 配合基因轉殖 (transgenics) 或剔除 (genetic knockout) 及蛋白體 (proteomics),發現一些抗藥基因。有些基因功能還受 p53 抑癌蛋白及ubiquitin-mediated proteasome 蛋白分解的調控。B 型肝炎病毒 HBx 蛋白或鼻咽癌EB病毒LMP-1蛋白所引起的細胞感染反應(譬如細胞生長及細胞死亡)。此外,我們更進一步運用RNAi配合基因轉殖 (transgenics) 或剔除 (genetic knockout) 及蛋白體學 (proteomics),探討是否提升藥效及篩選新藥。   

2.細胞分化、發育與疾病Cell differentiation, development and diseases):
本研究室另一個目標是探討細胞分化與個體發育及疾病的調控。藉由致癌,抑癌與凋亡基因(oncogene, tumor suppressor and apoptotic genes) 的遺傳操作,來分析細胞生長分化與移動,可以 找出關鍵的細胞分子以瞭解癌症及腦神經等疾病的部分成因,及有助於發展新的治療藥物。細胞分化必需先抑止生長 (growth arrest),在這個抑長 階段特別表現的抑長基因 (growth-arrest-specific gene,簡稱 Gas),可能決定細胞是否能夠順利分化,否則就會凋亡 (apoptosis)。我們與德國科學家分別發現了多個的抑長基因,其中我們發現的 Gas7 (growth-arrest-specific 7) 對小鼠及斑馬魚腦神經細胞及骨骼生成是必要的。 Gas7 也與細胞骨幹 (cytoskeleton) 譬如 F-actinmicrotubulin 結合,可以調節其 assembly,可能參與細胞骨幹的相關功能。我們的目的在藉此動物模式進一步探討該關鍵分子,在神經與骨骼肌肉系統的發育 (development) 恆定 (maintenance),以及人類腦神經退化及骨骼疏鬆的相關病理角色。
