科普專欄–薯不揀單 - 三十秒科學–基因突變對細胞的影響力（一）

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。559Please respect copyright.ＰＥＮＡＮＡ7Wox6qs0Gv

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。559Please respect copyright.ＰＥＮＡＮＡ0XAgRhpyNs

(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。559Please respect copyright.ＰＥＮＡＮＡjnsI8MhlAw

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。559Please respect copyright.ＰＥＮＡＮＡZOtCWuYGRg

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。559Please respect copyright.ＰＥＮＡＮＡOMMAVuhZGd

現今最為成功的例子為口服藥物Gleevec，詳情可參考延伸閱讀。559Please respect copyright.ＰＥＮＡＮＡ6EhrZZCnUV

(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。559Please respect copyright.ＰＥＮＡＮＡE21iZK9TxA

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。559Please respect copyright.ＰＥＮＡＮＡZ0jv4YAdPx
