Self-Introduction

許濤老師 研究室介紹

 

主要研究領域水生環境生物學、分子毒理學

 

相關研究領域環境毒物學、免疫學、生物技術、藻類分子生物學、應用免疫學

 

使用生物材料斑馬魚、小球單胞綠藻、大腸桿菌

 

研究計畫簡介

1.  熱休克蛋白70於斑馬魚發育過程中之自發性表現、其組織特異性分佈與轉譯調控熱休克蛋白70 為細胞內將變性蛋白質摺疊回正常構造之分子監護者(molecular chaperone)。自發性表現之熱休克蛋白70包括等電點分別為5.55.7Hsp70Hsc70,但Hsc70於受精84 小時候(84 hpf)斑馬魚中之自發性表現量為Hsp7010倍,然而Hsc70對熱休克之敏感度較Hsp70為差。當Hsc70尚未出現在36 hpf斑馬魚胚胎中時,全覆式原位雜交顯示其mRNA已廣泛分佈在各組織中反應出此Hsc70之自發性大量表現係於轉譯層次調控。由於Hsp70 mRNA有一較Hsc70 mRNA為長之5’端非轉譯區域,且Hsp70 mRNA於兔子紅血球抽取液中之轉譯效率明顯優於Hsc70 mRNA,因此5’端非轉譯區域在胚胎發育時期之修飾狀態與此區域結合蛋白之含量可能為調控Hsc70 mRNA轉譯能力之關鍵。

 

2.  化學物質引起之氧化壓力抑制斑馬魚胚胎DNA錯誤配對修補因子基因表現之機制真核生物中單一錯誤配對與配對不完全之小型寡核苷酸環由MSH2-MSH6蛋白複合體進行辨識,而MSH6為主要之辨識蛋白。本實驗室發現具致癌性之氯化鎘或殺草劑巴拉刈(paraquat)於非致死濃度下處理斑馬魚胚胎49小時可抑制MSH2/MSH6基因於 mRNA與蛋白質層及之表現,但不干擾β-actin基因活性。基於巴拉刈為一已知之superoxide radical(O2-)誘發劑與鎘對SOD之抑制效果,推論鎘應先引起具組織傷害性之氧化壓力,再以活性氧分子為主要迅號傳遞者調降斑馬魚胚胎中MSH基因表現,最終導致癌症之產生
