研究方向及研究室特色：

細胞自噬作用(Autophagy)是一種經由細胞遭遇壓力(如營養缺乏)所引發的一種細胞反應，自噬作用藉由細胞內膜構造的重組以及一連串訊息傳遞而產生前自噬體(preautophagosome)，再形成雙層膜構造(Isolation membrane/phagophore)，藉由此雙層膜結構包覆細胞質成為自噬體(autophagosome)，隨之自噬體便與溶小體結合為溶自噬體(autolysosome)，將其包覆之內含物分解。細胞自噬作用對於清除細胞內蛋白質的堆疊、破損的胞器以及外來感染的病原體扮演非常重要的角色，研究細胞自噬作用對於了解細胞如何拮抗細胞所面臨壓力至為重要。本研究室未來有下列幾個方向:

(1)       許多病毒的感染被發現會引起細胞自噬作用以促進病毒的複製，以C型肝炎為例，我們過去的研究(Journal of Clinical Investigation, 2011), 發現病毒感染宿主細胞會經由不正常蛋白質堆疊反應(unfolded protein response)引發自噬作用，而自噬作用則透過抑制即時性抗病毒免疫力的活化來促進病毒RNA基因體的複製。因循這些結果，未來本研究室利用分子生物學、蛋白質體學方法以及電子顯微鏡技術繼續探討細胞自噬作用如何透過調節調控即時性免疫反應訊息傳遞或是分子的運輸以抑制抗病毒免疫反應的活化。

(2)       許多病毒所引發之自噬作用多半透過不正常蛋白質堆疊反應而活化，截至目前為止，其詳細的分子機制依然不清楚；目前的研究顯示，由於病毒大多於內質網(endoplasmic reticulum)所形成的膜狀構造進行複製而產生的內質網壓力(endoplasmic reticulum stress)，因而誘發不正常蛋白質堆疊反應，再進而活化細胞自噬作用，本研究室將來將利用干擾性RNA以及轉錄基因體學的方法來探討究竟是什麼樣的分子在不正常蛋白質堆疊所引發的細胞自噬作用扮演重要的角色，而其透過的是什麼樣的分子機制，包括，基因轉錄、蛋白質新合成或是蛋白質轉錄後修飾等。

(3)       細胞自噬作用對於癌細胞發生及演進既是促進者也是抑制者的角色，目前對於自噬作用在癌症形成的過程其確切角色的相關研究結論依舊是混沌不清的，因此本研究室將對細胞自噬作用在國人常見的肝癌發生過程中扮演的功能角色進行探討。
