研究興趣

密碼子是將遺傳訊息傳遞到胺基酸以至於蛋白質的橋樑，也是分子生物學的中心法則的核心。絕大部分的胺基酸可以被兩個以上的同義密碼子表達，但是這些同義密碼子的使用頻率並不相同，我們稱這種現象為密碼子使用偏移。有趣的是，密碼子使用偏移存在於幾乎所有已知的基因體中，但是為什麼這種現象會在長久的演化過程中被保留下來，並不清楚。 我們之前的研究結果顯示，密碼子的使用偏移雖然不改變胺基酸的序列，卻可以調控蛋白質的摺疊以及調控信使核醣核酸與蛋白質的表達量。在臨床上，隨著定序技術的進步，越來越多的疾病也被發現是與序列中同義密碼子的突變有關。未來實驗室的研究將運用分子生物學、生物化學、遺傳學以及生物資訊學的方法，來探討為什麼密碼子使用偏移會影響基因表達的機制。也希望透過更深入了解密碼子使用偏移的機制，可以發展出治療同義密碼子突變相關疾病的方法。
