1. 肝癌發生 (hepato-carcinogenesis) 與 B 型肝炎病毒感染之關係與分子機轉: B 型肝炎病毒感染是導致肝癌很重要的原因。在癌症發生過程中,細胞常發生基因不穩定性(genomic instability)。因此維持基因的穩定與完整性對於預防癌症發生扮演重要的角色。我們發現 B 型肝炎病毒的表面抗原 pre-S2 突變種會造成基因不穩定性及造成 DNA 損害(DNA damage)。因此我們以 B 型肝炎病毒為 study model,探討慢性 B 型肝炎帶原者在轉變成肝癌的過程中 DNA damage 與 DNA repair 機制的調控及其對 HCC 發生的影響。

2. DNA Repair 之分子病理: DNA Repair (DNA修復) 是細胞內維持 DNA 結構完整及修復 DNA 損害最重要的一個機制。當生物體 DNA 受到環境途變原(environmental mutagens) 例如 x-ray,紫外線,以及有毒化學物質等刺激而引起 DNA 結構不正常時,就需靠 DNA Repair 功能來使之恢復正常功能。DNA Repair 功能異常的病人由於 DNA 突變率較高,導致癌症的機率較正常人高出許多。我們主要的研究方向為探討 DNA Repair 的分子機轉及其調控,尤其是近年來才分離出的因子 hHR23 A 及 hHR23B (human homolog of Rad23 A / B),探討其在 DNA Repair 過程中所扮演的角色。除此之外,我們也利用微矩陣(Microarray) 生物晶片技術來探討紫外線等環境途變原所引發的 DNA Repair 分子機轉。同時我們也進一步分析 DNA Repair 不正常病人的細胞株,以了解 DNA Repair 異常所引發的相關病理機制。
