癌細胞的新陳代謝與普通細胞有著顯著的分別，原因是癌細胞需要截然不同的新陳代謝來滿足生長的需要。761Please respect copyright.ＰＥＮＡＮＡkcSmhKhr22

但是，當癌細胞從原有位置轉移到另一位置後，其新陳代謝有會否有所轉變呢?761Please respect copyright.ＰＥＮＡＮＡ7b5t7DMnQI

（圖2）mTORC1是其中一隻掌管細胞生長的蛋白質，而有研究(Ref1)指出，從乳癌轉移到肺部的癌細胞，其mTORC1所帶來的效果更為強大，能令癌細胞生長得更快。761Please respect copyright.ＰＥＮＡＮＡf5HlFxYkH1

（圖3）科學家發現，肺部含有充足的Pyruvate代謝物，而利用藥物阻擋「乳癌轉移過來的肺癌」吸收Pyruvate的話，便能減低mTORC1的功效。761Please respect copyright.ＰＥＮＡＮＡVCWIFeepUQ

但奇怪的是，用藥物阻擋原發腫瘤乳癌吸收Pyruvate的話，mTORC1的功效並不會有所減低，腫瘤生長的速度並無任何特別變化。761Please respect copyright.ＰＥＮＡＮＡL5ur8aCZK2

這顯示出，癌細胞從原有地方轉移到另一位置後，其新陳代謝亦有著顯著的變化。761Please respect copyright.ＰＥＮＡＮＡirKRAMevvZ
這有可能是因為第二處位置的生長環境有所不同，故此癌細胞需要調節其新陳代謝來適應新環境。761Please respect copyright.ＰＥＮＡＮＡl59oAYhOej

在乳癌轉移到肺部的癌細胞，我們可透過針對Pyruvate的吸收來減慢他們的生長，但這是否只適用於從其他位置轉移到肺部的癌細胞，以及乳癌轉移到其他位置的癌細胞，那還需要進一步的研究確實。761Please respect copyright.ＰＥＮＡＮＡgxKBxfzeJk
