Abstract
背景與目的:減緩甚至消除腫瘤生長和轉移一直是癌症治療的主要目標。腫瘤相關巨噬細胞(tumor-associated macrophages, TAM)的浸潤(infiltration)所誘發之發炎反應會促進腫瘤的生長和存活(proliferation and survival)並誘發腫瘤血管新生與轉移(angiogenesis and metastasis),其中巨噬細胞分泌的抗酒石酸性磷酸酶(tartrate-resistant acid phosphatase, TRAcP)可能扮演重要角色。因此本研究欲探討M2巨噬細胞是否經由調控抗酒石酸性磷酸酶的表現促進腫瘤生長速度,以及其相關機制。
方法:我們將M2巨噬細胞與JC乳腺癌細胞經由不同組合方式(單純注射JC、M2和JC一起注射,先注射M2 30分鐘後再注射JC)注射至小鼠的乳腺皮下,經過14天後測量其腫瘤生長的速度、大小和重量、腫瘤的抗酒石酸性磷酸酶表現和血清中抗酒石酸性磷酸酶5a的濃度。
結果:實驗結果發現預先注射M2巨噬細胞30分鐘後再注射JC乳腺癌細胞之組別與其他兩組(單純注射JC以及M2和JC一起注射)比較能顯著促進小鼠乳腺癌細胞之生長,而且這與腫瘤抗酒石酸性磷酸酶的表現增加有關。
結論:M2巨噬細胞可以藉由調節抗酒石酸性磷酸酶影響腫瘤相關環境,進而顯著促進小鼠乳腺癌細胞之生長。因此,抗酒石酸性磷酸酶可能可作為臨床監測乳癌癌症預後的生物指標或標靶治療的目標。
