實驗室研究題目四大方向:
口腔鱗狀細胞癌(OSCC)是全世界中最常見的癌症之一,並且罹癌概率具有區域特異性。儘管口腔癌的診斷與治療方法上有突破性的進展,但是病患的五年存活率並未被顯著提升。進一步理解口腔癌的致病機轉,特別是其中的分子機制,將助於口腔癌的診斷、預防以及治療。近年來因為次世代定序技術的進步,使得過去許多未被發現的非編碼轉錄組體,包含長鏈非編碼轉錄本(lncRNA)、環狀核醣核酸轉錄本(環狀RNA)得以被廣泛的偵測表達,並且證實其具備潛力成為口腔癌症的生物標誌物。本實驗室針對非編碼轉錄本進行一系列功能性分析試驗,以理解其介導的調控網絡對於口腔癌症細胞的生長、轉移、以及藥物反應中扮演的生物角色。透過體學基礎的系統性分析方法所得到的實驗結果,將提升非編碼轉錄體應用於轉譯醫學的潛力。
食道鱗狀上皮細胞癌 (ESCC)是亞洲常見的惡性腫瘤,患者多為中晚期,造成低存活率與不良的預後。而癌症診斷常具有侵入性使患者不適,因此液態生物檢體將是突破這個困境的新星之一。為了尋找能早期診斷食道癌的生物標誌 (Biomarker),我們與長庚醫院合作收集病患與健康受試者的血漿,收取胞外囊泡中的小RNA進行次世代定序,挑選有潛力辨別疾病的微小核醣核酸 (miRNA)。進一步以功能性測試了解胞外囊泡與miRNA具有影響癌細胞的轉移能力、對藥物的敏感性與免疫調控。因此,我們除了探討這些生物標誌在癌症中的功能,更希冀能幫助食道癌早期檢測,並協助預測患者接受治療後的反應,以達到精準醫學的應用與實踐。
RNA編輯可以改變RNA序列並以此增加序列多型性。在神經細胞中許多的蛋白都會受到編輯,並藉此得到蛋白多樣性,以快速調節腦部遇到特定刺激所需的反應。實驗室針對具有腦區的好發性、會導致重編碼與演化上的高度保留的編輯目標去做研究,建立基因剃除和基因單點突變兩種小鼠模式,並依據初步的分析結果,設計一系列動物實驗分別探討特定蛋白之編輯事件在中樞神經系統與行為認知相關的功能性呈現與意義。目前,發現特定標的有過動和學習困難等病徵。為更了解此模式動物的病徵且應用於後續治療上,將進行專注力、學習和中樞神經刺激物治療、成癮等實驗,藉此來探討特定蛋白和其編輯態參與在神經發育和過動症疾病當中的角色。此外,也發現特定蛋白和阿茲海默症有相關聯。在此基因剃除鼠中,能觀察到阿茲海默症模式鼠會有較快發病的結果,包含模式鼠步伐不穩、肌力退化及學習能力退化等等,因此也將針對其機制做一系列探討。 執行中的計畫 Ongoing Research Support 國科會專題研究計畫 2023/08/01 ~ 2026/07/31 剖析重新編碼之UNC80於神經生理中恆定離子與能量之角色
