世間建築各具特色,而事實上,我們身體的細胞亦有著自己的一套「建築構念」。459Please respect copyright.PENANAczFoyoEyAm

(圖2)正常的乳房細胞在體外培植的時候,當繁殖數量去到一定程度時便會停止生長,並建構出與體內相似的腺胞結構(acini)。459Please respect copyright.PENANAviABD3Cq6u

而乳房癌細胞在體外培植的時候,則會無止境地生長,結構雜亂無章,不會展現出腺胞結構形狀。459Please respect copyright.PENANAFQPBZPEPvE

(圖3)癌細胞不依正常預設方式生長的話,除了不斷增大,更會開拓出轉移到其他器官的可能。459Please respect copyright.PENANAvMBicGKrvz

當p53蛋白質發生變異的時候,乳房細胞呈現正常腺胞結構的比例會因而減少。459Please respect copyright.PENANAy6NMZuDrXX

事實上,癌細胞出現p53蛋白質特定位置的變異後,在老鼠身上出現轉移的機率亦會大增。459Please respect copyright.PENANAfdLmnvCCdc

上集講及了癌細胞缺氧會引致p53蛋白質發生變異,而這道研究亦佐證了其異變為癌細胞帶來的好處。459Please respect copyright.PENANAbvoQotnYDn
