Abstract
子宮內膜異位症(endometriosis)是一種常見於生育年齡婦女的疾病,其定義為子宮內膜出現及生長於子宮以外的部位,其最常出現的併發症是痛經與不孕症(infertility),約有30%的患者有不孕症的問題。造成子宮內膜異位症的病因尚未完全明確,目前許多研究認為當環境適當而且免疫系統無法清除異位內膜組織時,異位子宮內膜組織便能夠生長,造成子宮內膜異位症。本實驗中以濾泡液及腹腔液作為檢體,以蛋白質體學(proteomics)的方法-二維電泳(two-dimensional electrophoresis),比較子宮內膜異位症與正常病人的濾泡液及腹腔液中蛋白質組成是否有所不同,找出表現量不同的差異性蛋白質以期增加對子宮內膜異位症病理機轉的了解及找出適用的疾病診斷標記。我們嘗試以不同的二維電泳條件包括:檢體前處理、染色方式、等電點電泳條件、IPG strip的選擇,以求出最適合本實驗的狀態,經比較二維電泳膠片之後判斷出穩定出現於每次實驗,及具有差異表現量的蛋白質,且針對這些蛋白質進行了質譜儀分析,鑑定出穩定表現量的蛋白質包括有:serotransferrin、serum albumin、alpha-1 -antitrypsin、actin、apolipoprotein A-1、及transthyretin;在腹腔液中內膜異位組表現量高於對照組2倍的蛋白質有:haptoglobin-2,fibrinogen。以西方墨點法(Western blot)確認腹腔液中serotransferrin、apolipoprotein E、及apolipoprotein A-1的表現量在內膜異位組及對照組相近,無顯著差異。以西方墨點法偵測fibrinogen的表現量並無顯著差異,而腹腔液中haptoglobin的表現量在內膜異位組及對照組雖無顯著差異,但是58.33%內膜異位組的病人表現量高於對照組平均值,顯示在內膜異位組haptoglobin有升高的趨勢。
