科普專欄–薯不揀單 - 三十秒科學–乳癌細胞的結構

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」。594Please respect copyright.ＰＥＮＡＮＡjFqSwZ3jj2

（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)。594Please respect copyright.ＰＥＮＡＮＡZtTiRx9GJc

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。594Please respect copyright.ＰＥＮＡＮＡ2Zqcl1uuvk

（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。594Please respect copyright.ＰＥＮＡＮＡFM97s6CgO3

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。594Please respect copyright.ＰＥＮＡＮＡj7MhgSIMjr

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。594Please respect copyright.ＰＥＮＡＮＡ1zNPzFCH7H

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。594Please respect copyright.ＰＥＮＡＮＡ2IBzdg5Jve
