  • 1.One possible new treatment strategy: preventing EGFR from binding to the glucose transport protein. It is possible, Fidler adds, that it will take a two-hit approach to defeat EGFR's dual role in promoting growth and survival of tumor cells.

    一个可能的新治疗策略:阻止EGFR与葡萄糖转运蛋白结合。Fidler补充说,这一新策略有可能对EGFR促进肿瘤细胞的生长和生存的双重作用产生双重打击。

  • 2.For years researchers have been trying to understand how a few HIV-infected patients naturally defeat a virus that otherwise overwhelms the immune system. Last year, a research team at the University of Rochester Medical Center confirmed that such patients, called long-term non-progressors, maintain higher than normal levels of the enzyme called APOBEC-3G (A3G) in their white blood cells, which function to stave off infections. Now, the same group has teamed up with a structural biologist to provide the first look at the A3G structure. Such information represents an early step toward the design of a new class of drugs that could afford to all the same natural protection enjoyed by few, according to a study published today in The Journal of Biological Chemistry.

    对蛋白结构最初的观察为以后的新药设计找到方向。多年以来,研究者都一直努力了解,当病毒已侵袭整个免疫系统,少数感染HIV的患者如何还能自身战胜病毒。去年,Rocheste大学医学中心的研究小组证实,这类病人,也就是“长期非进行者”的白细胞中的A3G酶维持在比正常情况下更高的水平,这种酶有避免感染的功能。现在,同一研究组联合一位结构生物学家来一同首次揭开A3G的结构。根据发表于《生物化学期刊》的相关研究,这一信息代表了向设计出具有相同自然保护的新药提前迈进了一步。

  • 3.Intelligent design (ID) received a drubbing yesterday, with pro-evolution candidates taking control of the Kansas State Board of Education and strengthening their representation on the Ohio State Board of Education. Many scientists also cheered the defeat of Senator Rick Santorum (R-PA), one of the most politically influential supporters of the ID movement.

    随着后进化论候选人控制堪萨斯州教育委员会及其代表性在俄亥俄州教育委员会的增强,昨天,智力测试(ID)遭受挫折。很多科学家也对Rick Santorum参议员(对ID运动最有政治影响力的支持者之一)的失败表示高兴。

  • 4.“The implication is that once you know the mechanism by which tumors evade the immune system, you can match that tumor to available therapies,” said senior author Alan L.Epstein, M.D., Ph.D., professor of Pathology at USC's Keck School of Medicine. “First, we find the genetic changes that allow a tumor to defeat the immune system, then we can apply therapies that compensate for these genetic alterations.”

    “很明显,一旦识破了肿瘤逃避机体免疫监视的机制,我们就能给予该肿瘤相应有效的治疗,”南加州大学Keck医学院病理学教授、论文资深作者Alan L.Epstein医学博士说,“首先,我们在肿瘤细胞中发现了某些可以导致肿瘤逃避机体免疫监视的遗传改变;然后,我们通过修正这些遗传改变来进行肿瘤治疗。”

  • 5.But the House margin of 265 to 159 is about two dozen short of the two-thirds needed to defeat Mr. Bush's veto. Democrats have been trying to pressure some Republicans loyal to the president to switch sides. But if the House sustains his veto, Mr. Bush said, he hopes there will be negotiations to get S-chip money to those it “was intended to help first and foremost.”

    但是白宫的表决265比159还差大约两打才能达到推翻布什的否决所需的三分之二的比例。民治党已经试图压迫某些忠于布什的共和党人动摇。但是布什说如果白宫支持他的否决的话,他希望通过协商把S-chip的资金用于最需要的人。
