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。693Please respect copyright.PENANAwC2JnPtBTg

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?693Please respect copyright.PENANAzsU8994c6b

(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。693Please respect copyright.PENANAYzsfTnFQK2

(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。693Please respect copyright.PENANA8N6oYe75jJ

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。693Please respect copyright.PENANAKABbizou2z

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。693Please respect copyright.PENANAdhePuId2fF
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。693Please respect copyright.PENANAdYSXQOGJCW

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。693Please respect copyright.PENANAHnUNIiKLTO
