研究人員在11月2日出版的英國《自然—遺傳學》雜志上宣布,他們發現兩種
基因變異可能導致患
肺癌的幾率增加60%。
據路透社報道,來自18個國家的
科學家參與了此項研究。研究對象包括6000名肺癌患者和9000名非肺癌患者。
科學家們在對比研究對象的基因后發現,位于第五條染色體某個區域內的兩種基因TERT和CRR9的變異可能使患肺癌的幾率增加高達60%。
據
美國癌癥學會統計,在全球范圍內,肺癌是導致男性癌癥患者死亡的首要原因,也是導致女性癌癥患者死亡的第二大原因。吸煙一直被認為是肺癌的主要誘因,但是一些長期吸煙的人從未罹患肺癌,而一些不吸煙的人反而罹患肺癌,因此促使研究人員更多地從基因角度尋找肺癌病因。(來源:新華網)

We carried out a genome-wide association study of lung cancer (3,259 cases and 4,159 controls), followed by replication in 2,899 cases and 5,573 controls. Two uncorrelated disease markers at 5p15.33, rs402710 and rs2736100 were detected by the genome-wide data ( P = 2 * 10 -7 and P = 4 * 10 -6 ) and replicated by the independent study series ( P = 7 * 10 -5 and P = 0.016). The susceptibility region contains two genes, TERT and CLPTM1L , suggesting that one or both may have a role in lung cancer etiology.
