1.肝癌發生(hepato-carcinogenesis)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 damageDNA 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 AhHR23B (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。
