  • 研究領域--基因剔除小鼠,心血管發育,顱顏形成,腫瘤形成與基因調控
    我的實驗室主要以組織/細胞特異性基因剔除小鼠(conditional knockout mouse)為動物模式,探討基因在發育及癌症形成所扮演的角色。在發育相關的研究,目前有心臟血管(心中隔缺損)、造血幹細胞之生長和分化及顱顏形成(唇顎裂)的小鼠模式,依所觀察到的缺陷性狀探討參與其中重要基因調控及訊息傳導。在癌症形成方面,主要探討肝癌及大腸癌的致病過程及訊息傳導。近年來,飲食西化易造成肥胖及糖尿病等問題之外,更可導致脂肪肝,進而演變成肝硬化或肝癌形成,我們也建立以diethylnitrosamine(DEN)誘導肝癌發生及高脂食物餵食小鼠模式來模擬人類肝癌發生的狀況;此外,也利用藥物azoxymethane(AOM)+ dextran sodium sulfate(DSS)誘發小鼠炎症相關大腸癌模式,模擬人類大腸炎症及大腸癌發生。希望我們建立的基因剔除鼠資源得以用來研究發育缺陷成因、生理恆定及細胞癌化之重要分子調控。
    Transgenic and knockout mice are powerful model systems for understanding embryonic development and disease progression. In the past, several knockout mouse models have been established in my laboratory. In combination with molecular and biochemical approaches, these mouse models are valuable tools for dissecting the mechanisms of the developmental defects (craniofacial and cardiovascular defects) and tumorigenesis (cancer initiation and the effects of diet or carcinogens on cancer promotion and progression).
