美國全國癌癥研究會在其網站上指出，甜葉菊甙的主要化學成分在實驗室可以被轉化為能改變基因的物質，而要確定這種甜味劑能否導致癌癥還需進一步研究。The us national cancer institute says on its website that the main chemical in stevioside can be converted in a laboratory into a substance that alters genes. further study is needed to determine whether the sweetener can cause cancer it says
美國全國癌癥研究會在其網站上指出，甜葉菊甙的主要化學成分在實驗室可以被轉化為能改變基因的物質，而要確定這種甜味劑能否導致癌癥還需進一步研究。Exposure to genistein, an estrogen, before puberty causes mammary gland differentiation. " a differentiated cell undergoes less proliferation and therefore is less likely to progress through the cancer process, " he said. " howeer, if the estrogen is administered to an animal after the deelopment of an estrogen - responsie tumor, the growth of this tumor will be stimulated, " he said
青春期前服用雌激素染料木素可導致乳腺分化， 「分化的細胞很少增殖，因而很少發生癌變；然而，如果已經患有雌激素反應腫瘤的動物服用雌激素，則刺激腫瘤的生長。 」This study raises hope that they might have another option - - using drugs rather than surgery to guard against cancers linked to the mutated gene
這一研究使他們有了另一個選擇的希望?應用藥物而不是手術來對抗因基因突變而致的癌癥。Many constituents are mutagens and carcinogenic such as alkenes, nitrosamines, polynuclear aromatic and heterocyclic hydrocarbons, amines

化學致癌物能直接在dna上造成修飾和損傷：如果沒有被正確修復，這些損傷將導致突變的形成。Think now, undesirable disposition sends cancer to adopt 3 approaches : it is to promote cancer cell to grow ; the 2 immune force that are scathing airframe ; the 3 active that are enzymatic department of change airframe small system, affect the change of other and chemical carcinogen
現認為，不良性格致癌通過三條途徑：一是促進癌細胞生長；二是損傷機體的免疫力；三是改變機體微體酶系的活性，影響其他化學致癌物質的轉變。Rapl belongs to ras superfamily of small gtp - binding proteins, which is considered to control cell growth, differentiation and survival. rapl was regarded as an antagonist of ras because it can revert the phenotype of oncogene ras transformed cells. recent researches show that rapl has its ras - independent functions in a variety of cellular systems besides its effect as an antagonist of ras
Rap1除具有逆轉原癌基因ras激活突變體所導致的細胞形態改變而被認為是ras的拮抗物外，最近的研究還發現rap1在一系列的細胞系統中有獨立於ras之外的功能，如控制與細胞粘附有關的事件等，因而成為研究的熱點。分享友人
