隨著細胞的基因變異一直累積，正常細胞形成癌細胞的機會亦會相應提升。540Please respect copyright.ＰＥＮＡＮＡuoJLBVrsMQ

但細胞是否只需要基因變異這一個誘因便能夠轉化為癌細胞呢？540Please respect copyright.ＰＥＮＡＮＡSGU7YxOfFy
540Please respect copyright.ＰＥＮＡＮＡ4Kc5hUq7Ie
這一方面還有一定程度的斟酌空間。540Please respect copyright.ＰＥＮＡＮＡSPFXJStBuS

舉例來說，NOTCH1基因變異被認定為是推進食道細胞轉化成為癌細胞的其中一個原因。540Please respect copyright.ＰＥＮＡＮＡhJApcnRqz9
540Please respect copyright.ＰＥＮＡＮＡhtlYi4AZPV
但在長者的健康食道細胞裡頭，約有30-80%的細胞均擁有NOTCH1基因變異，而他們身體並沒有出現及發生食道癌。540Please respect copyright.ＰＥＮＡＮＡH10gct986r

（圖2）而在老鼠實驗方面，單憑服用DMBA (引致Hras基因變異)或Croton oil(引致發炎效用，不會促進基因變異)的話，並不會引起癌細胞的出現。540Please respect copyright.ＰＥＮＡＮＡPDbWaj3tOY
540Please respect copyright.ＰＥＮＡＮＡdjSpcyh0yL
唯獨兩者以先後的方式給予老鼠的話，癌細胞才會有所形成。540Please respect copyright.ＰＥＮＡＮＡ4N94ZAtOvE

這不禁讓科學家開始思考一道問題，是否基因變異再加上某種特定條件，就可以促進癌細胞形成呢？540Please respect copyright.ＰＥＮＡＮＡ1FYlW7XkZo

（圖3）為解答這個問題，英國開始了名為Mutographs的計劃，540Please respect copyright.ＰＥＮＡＮＡdbc5vX5t0H

集5大洲超過5000個病人的癌細胞基因圖譜(主要集中在食道、大腸、腎臟及胰臟癌)，540Please respect copyright.ＰＥＮＡＮＡrK5gOEqbhU
540Please respect copyright.ＰＥＮＡＮＡa5d1Jiox3z
同時比對病人的日常習慣(食用習慣、酒精飲用、熱飲喜好等等)，540Please respect copyright.ＰＥＮＡＮＡlAx9rYrLxu
540Please respect copyright.ＰＥＮＡＮＡ1jRVtXTtZc
其中一個目標就是想找出哪一種特殊條件配上某一個基因變異會特別容易促進癌細胞的形成。540Please respect copyright.ＰＥＮＡＮＡ7cvZukzgXc

若然能得出確切的結果並附上內裡的細胞機制支持的話，這將會為預防癌症形成的領域作出重大的貢獻。540Please respect copyright.ＰＥＮＡＮＡTwirMeWRkp
