Abstract
由於先前文獻利用DNA微陣列 (microarray analysis) 偵測與乳癌相關的基因,發現HMGCS2在乳癌腫瘤細胞中大量表現,而此研究並未進一步深入探討。本篇利用乳癌細胞株和乳癌臨床檢體探討HMGCS2在乳癌中的機轉與作用。首先,利用Real-time PCR偵測122名乳癌病人HMGCS2的表現,初步觀察到,在病人檢體中HMGCS2在乳癌組織的表現,大於正常組織25倍;並在年齡小於52歲 (中位數)、HER2過度表現、三重陰性 (Triple Negative) 的病人腫瘤組織,HMGCS2的表現量也高於正常組織,且都達到統計上的顯著差異。接著,我們再利用13株乳癌細胞株進行RT-PCR及Western Blot,發現的確HMGCS2在mRNA及蛋白上亦大量表現;並且發現EGF會透過調控HMGCS2 promoter而導致HMGCS2表現量上升。另外,由IP的實驗結果觀察到,在受到EGF刺激後,HMGCS2會與PPARα交互作用;進一步地利用核質分離實驗以及螢光免疫染色實驗發現,HMGCS2在處理EGF後,會從細胞質轉移到細胞核;ChIP證實HMGCS2可能為一個轉錄因子,調控HMGCS2或下游基因,同時HMGCS2也受到p300、SP1及c-jun調控。因此,本篇研究推論,HMGCS2可能為一個轉錄因子,並且受到EGF所調控。未來,我們將透過RNAi和Overexpression的方式,抑制或大量表現HMGCS2,驗證HMGCS2在乳癌之角色。
