美国得克萨斯大学西南医疗中心的研究人员最近称,他们在肺癌和结肠癌肿瘤中发现了一种新的基因,并初步认定其与癌症有关。当这种基因有缺陷时,过量的磷酸盐就会积聚在控制细胞生长的蛋白质上,蛋白质因而不能执行其正常功能,使细胞生长失去控制,恶化成肿瘤。 据该研究项目负责人格兰·埃文斯称,该基因是在癌症基因“云集”的人体细胞第十一染色体上发现的。诱发子宫癌、卵巢癌、肺癌、结肠癌以及其他几种癌症的基因都被认为处于这一区域,只是一直没有证实。 Researchers at the University of Texas Southwestern Medical Center recently stated that they have discovered a new gene in lung and colon cancer tumors and have initially identified it as being associated with cancer. When this gene is defective, excess phosphate accumulates on proteins that control cell growth, and the protein cannot perform its normal function, leaving the cell growth out of control and becoming a tumor. According to the research project leader, Glen Evans, the gene was found on the eleventh chromosome of human cells where cancer genes “grew together”. Genes that cause uterine cancer, ovarian cancer, lung cancer, colon cancer, and several other cancers are considered to be in this area, but they have not been confirmed.
