Abstract
多型性神經膠質母細胞瘤 (glioblastoma)是最常見且致死率最高的腦部腫瘤。患者通常接受標準療法:手術切除後接受放療合併使用化療藥物帝盟多 (temozolomide),許多新穎性治療也應用在再復發的多型性神經膠質母細胞瘤,包括血管新生抑制劑及免疫查核點抑制劑。然而目前臨床上多型性神經膠質母細胞瘤的預後和整體存活率依舊很差,因此迫切需要開發更新穎有效的藥物來對抗多型性神經膠質母細胞瘤。萘醌結構天然物及其衍生物因其廣泛的藥理特性而受到關注,除了抗菌、抗炎、抗血小板等功效外,更被報導具有多樣化抗癌機轉。我們實驗室篩選出一個具有抑制血管新生作用的新穎萘醌結構衍生物WTH,本論文我們進一步探討WTH抗多型性神經膠質母細胞瘤之藥理作用以及其可能機轉。實驗結果顯示WTH能夠抑制神經膠質母細胞瘤細胞增生並誘導細胞凋亡,其機轉可能透過調控細胞週期調控蛋白cyclin D1、p21,以及抗凋亡蛋白survivin的表現。我們也建立神經膠質母細胞瘤原位移植動物模型,實驗結果顯示WTH可抑制神經膠質母細胞瘤在Balb/c裸鼠及C57BL/6小鼠體內的生長。概括來說,WTH 可透過影響神經膠質母細胞瘤細胞內STAT3活性及AMPK-p38MAPK訊息路徑來調控p21、survivin的表現,進而抑制神經膠質母細胞瘤細胞增生並誘導細胞凋亡。
