Abstract
順氯氨鉑為一被廣泛使用和具有高效用的化療藥物,現已證明其可應用在治療睪丸,卵巢,膀胱和胃腸道等癌症,其療效與其投與劑量相關,然而給予劑量愈高也愈容易引發腎毒性,約有三分之一患者在投與此藥後發生腎損傷,其臨床使用因而受限。本研究的目的是探討經順氯氨鉑引發腎病變後產生差異的蛋白質,以助於早期診斷、預防和分類順氯氨鉑引發之急性腎損傷。6週齡雌性BALB / c小鼠腹腔注射順氯氨鉑5毫克/每公斤體重/天,連續給藥3天或5天後犧牲取得尿液、血清及腎組織。由血中尿素氮、尿中尿酶NAG及腎臟組織確認小鼠腎損傷被成功誘導。將腎均質液以DAABD - Cl衍生化後,利用螢光高效液相層析法分析。最後,將表現量產生變化的蛋白質經LC-MS/MS與 Mascot數據庫檢索系統分析,得到結果。連續給予順氯氨鉑3天的小鼠,與正常小鼠的腎臟相較,共有Catalase、Parkinson disease protein7…等,33個蛋白質的表現出現顯著差異 (P<0.05);連續給藥5天的小鼠腎臟組織中,僅有glial fibrillary acidic protein、peroxisomal membrane protein 20 …等,9個蛋白質的表現有顯著變化 (P<0.05)。由此結果可知,順氯氨鉑可能經由抗氧化和發炎機制誘導小鼠發生急性腎損傷;並且在5天之後,可能因損傷過於嚴重使得蛋白表現趨於鈍化。本研究成功建立以螢光高效液相層析分離小鼠腎臟蛋白質,它可能有助於找到新的生物標誌物,以提高早期發現順氯氨鉑引起的急性腎損傷。
