东京12月3日电日本京都大学2日发表公报称,其研究人员弄清了1种致癌蛋白质怎样发挥作用,这将有助于开发治疗多种癌症的新药。多达90%的胰腺癌和约40%的大肠癌都源于1种叫作Ras的蛋白质,白血病和肺癌等也与其有关。这种蛋白质变异并激活后,就会促使细胞异常增殖,最终引发癌症。直接

TOKYO, December 3 - Japan’s Kyoto University said in a statement on the 2nd that its researchers have figured out how one oncogenic protein plays a role, which will help to develop new drugs to treat many cancers. Up to 90% of pancreatic cancers and about 40% of colorectal cancers originate from a protein called Ras, which is also associated with leukemia and lung cancer. This protein mutation and activation, it will promote abnormal cell proliferation eventually lead to cancer. direct
