當細胞不斷累積不同數量及數目的基因變異,而細胞又沒能修復其變異的話,癌細胞便有機會形成。893Please respect copyright.PENANAikAs9bVslx

隨著我們的年紀遞增,細胞修復基因變異的能力亦會順之減弱,因此年紀越大,患癌的機率亦會越高。893Please respect copyright.PENANAtpec1T4vIG

(圖2)科學家一直致力研究,希望能找出哪一些的基因變異會導致癌細胞的形成。893Please respect copyright.PENANA6tDt34OyEy

在治療癌症的角度來看,當某特定的基因出現變異後,細胞所運行的機制便會與正常細胞所運行的有所不同。893Please respect copyright.PENANAQLPACh8OEn
893Please respect copyright.PENANAXnUTM8hHOj
若我們能對症下藥針對其癌細胞所運行的變異機制,而其變異機制同時亦是癌細胞生存的救命草的話,那便會是一道非常有效消滅癌症的手法。893Please respect copyright.PENANA11hqn69f82

現今最為成功的例子為口服藥物Gleevec,詳情可參考延伸閱讀。893Please respect copyright.PENANAr1ZQegNAxM

(圖3)圖中為老鼠小腸細胞的圖片,藍色區域為細胞核,紅色區域為發生對應基因變異的細胞,而白色區域則為正在進行自我複雜程序的細胞。893Please respect copyright.PENANAvROZdGldj3

893Please respect copyright.PENANAwtn1wllUDD
透過計算有多少細胞(對比紅白藍區域)正在進行自我繁殖的工序,科學家便能夠推敲那一款基因的變異將有助癌細胞生長。893Please respect copyright.PENANA47OOjfq3py

此為序章,下集將會更深入癌細胞基因變異後對周遭帶來的禍害。893Please respect copyright.PENANAcNstNbAEQk
