科普專欄–薯不揀單 - 三十秒科學–癌細胞裡頭的油脂粒

前列腺癌與正常前列腺細胞的其中一道不同之處，就是前列腺癌細胞裡頭含有豐盛的油脂粒(Lipid Droplet)。461Please respect copyright.ＰＥＮＡＮＡ6QjCGoVUrc

油脂粒為細胞儲存脂肪的一道地方，在不少癌症例如乳癌、腸癌及腦癌也能找得到數量充盛的油脂粒。461Please respect copyright.ＰＥＮＡＮＡSlG1KmjGa9

（圖2）前列腺癌細胞油脂粒的主要成份，是名為Cholesteryl ester (CE)的物質，461Please respect copyright.ＰＥＮＡＮＡgELPP88z32
簡單來說可以看成為脂肪酸與膽固醇結合在一起的物質。461Please respect copyright.ＰＥＮＡＮＡyDiI3DZx5c

（圖3）CE，亦即是前列腺癌細胞油脂粒的主要成份，是依靠細胞裡頭一隻名為ACAT的蛋白酶製作而成。461Please respect copyright.ＰＥＮＡＮＡCK0md6re1w

利用抑壓ACAT的藥物不但之能夠將老鼠的前列腺腫瘤縮小，更對老鼠身體的其他器官及細胞並無做成任何大的影響。461Please respect copyright.ＰＥＮＡＮＡrMbMytBzJe

某部份的前列腺癌細胞可依靠抑壓雄激素來阻止其生長，但此方法並非絕對有效，某部份的前列腺癌細胞並不依賴雄激素亦能快速生長及轉移到骨頭等各身體部位。461Please respect copyright.ＰＥＮＡＮＡl0SWuGppnb

在這種情況下，針對前列腺癌細胞的油脂新陳代謝來抑壓其生長，未嘗不是一道可行的方向。461Please respect copyright.ＰＥＮＡＮＡp6yS7oqqqm
