"The Nobel Assembly at Karolinska Institute has today decided¹ to award the 2019 Nobel Prize in Physiology² or Medicine jointly³ to William Kaelin, Sir Peter Ratcliffe and Gregg Semenza for their discoveries of how cells sense and adapt to oxygen availability."

“卡罗林斯卡学院诺贝尔大会今天决定将2019年诺贝尔生理学或医学奖共同授予威廉·凯林、彼得·拉特克利夫爵士以及格雷格·塞门扎，以表彰他们发现了细胞如何感知和适应氧气的可用性。”

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

美国东部时间早上5点30分稍过，诺贝尔大会秘书托马斯·珀尔曼宣布了这一消息。

"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 Oxford⁴ 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·塞门扎1956年出生于纽约。他在巴尔的摩的约翰·霍普金斯大学进行获奖研究，现在依然在该校从事研究。彼得·拉特克利夫爵士1954年出生于英国的兰开夏郡。他在牛津大学进行获奖研究。他现在仍在牛津大学和伦敦的弗朗西斯克里克研究所从事研究工作。威廉·凯林1957年出生于纽约，他在波士顿的丹娜·法伯癌症研究院进行获奖研究，目前仍在自已的实验室从事研究工作。”

Karolinska Institute researcher Randall Johnson studies the effects of low oxygen. He explained the significance of the work of the new Nobel laureates:

卡罗林斯卡学院的研究员兰德尔·约翰逊研究低氧效应。他解释了新任诺贝尔获奖者的研究的重要性：

"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 molecular⁵ switch that regulates how our cells adapt when oxygen levels drop."

“今年的诺贝尔奖颁发给确定细胞感知氧气水平方式的科学家。氧气是生命所必需的，几乎所有动物细胞都用氧气将食物转化为可用能量。然而，细胞、组织和动物本身所能获得的氧气量可能在很大差异。这个奖项颁给三位医生科学家，他们发现了一种分子开关，可以在氧气水平下降时调节细胞的适应方式。”

"Applications of these findings are already beginning to make their way to the clinic, with potential drugs used to treat anemia⁶ 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 physiological⁷ response makes life possible."

“这些发现和用于治疗贫血和某些癌症的潜在药物一起，已经开始进入临床应用。这些基础发现大大增加了我们对人体如何适应变化的理解。这些发现的应用已经开始影响医学实践的方式。今年的三位获奖者极大扩展了我们对生理反应如何使生命成为可能的认知。”
