因研究細胞感知氧氣水平而獲得諾貝爾生理學或醫學獎

The Nobel Assembly at Karolinska Institute has today decided to award the 2019 Nobel Prize in Physiology or Medicine jointly to William Kaelin, Sir Peter Ratcliffe and Gregg Semenza for their discoveries of how cells sense and adapt to oxygen availability.

“今天,卡羅林斯卡學院的諾貝爾委員會決定將2019年諾貝爾生理學或醫學獎聯合授予威廉·凱林、彼得·拉特克利夫爵士和格雷格·塞門扎,以表彰他們在細胞感知和適應氧氣供應方面的發現。”

Thomas Perlmann, secretary of the Nobel Assembly, shortly after 5:30 A.M. (Eastern Time).

諾貝爾大會秘書托馬斯·珀爾曼在美國東部時間早上5點30分剛過時宣布。

Gregg Semenza was born in 1956 in New York. He performed his prizewinning studies at Johns Hopkins University in Baltimore, where he's still active. Sir Peter Ratcliffe was born in 1954 in Lancashire in the U.K. He performed his prizewinning studies at Oxford University. And he's continuing to do his research at Oxford University, and he's also at the Francis Crick Institute in London. And William Kaelin, born in 1957 in New York - he performed his prizewinning studies at the Dana-Farber Cancer Institute in Boston, where he's still active in his own lab.

格雷格·塞門扎1956年出生于紐約。他在巴爾的摩的約翰霍普金斯大學完成了他的獲獎研究,在那里他仍然很活躍。彼得·拉特克利夫爵士1954年出生于英國的蘭開夏郡。他的獲獎研究完成于牛津大學,而且他目前仍繼續在牛津大學和倫敦的弗朗西斯克里克研究所做研究。1957年出生于紐約的威廉·凱林在波士頓的丹娜-法伯癌癥研究所完成了他的獲獎研究,獲獎后他也仍然活躍在自己的實驗室。

Karolinska Institute researcher Randall Johnson studies the effects of low oxygen. He explained the significance of the work of the new Nobel laureates:"This year's Nobel Prize is awarded for determining how oxygen levels are sensed by cells. Oxygen is essential for life and is used by virtually all animal cells in order to convert food to usable energy. However, the amount of oxygen available to cells, tissues and animals themselves can vary greatly. This prize is for three physician-scientists who found the molecular switch that regulates how our cells adapt when oxygen levels drop.

卡羅林斯卡學院的研究員蘭德爾·約翰遜研究低氧的影響。他解釋了新諾貝爾獎得主工作的重要性:“今年的諾貝爾獎頒發給了確定細胞如何感知氧氣水平的科學家。氧是生命所必需的,幾乎所有的動物細胞都利用它把食物轉化為可用的能量。然而,細胞、組織和動物本身所能獲得的氧氣量卻有很大的不同。這個獎項是頒給三位科學家的,他們發現了一種分子開關,可以調節細胞在氧氣水平下降時的適應能力。”

Applications of these findings are already beginning to make their way to the clinic, with potential drugs used to treat anemia and to treat some forms of cancer. These fundamental findings have greatly increased our understanding of how the body adapts to change. And applications of these findings are already beginning to affect the way medicine is practiced. This year's three laureates have greatly expanded our knowledge of how physiological response makes life possible.

“這些發現的應用已經開始進入臨床,可能用于治療貧血和某些癌癥的藥物。這些基礎發現大大增加了我們隊身體如何適應變化的理解。這些發現的應用已經開始影響醫學實踐的方式。今年的三位獲獎者極大地擴展了我們對生理反應如何使生命成為可能的認識。”
