Fat-clogged cells explain why obesity can cause cancer 被脂肪阻塞的細(xì)胞可解釋為何肥胖能致癌
科學(xué)家們稱，一項(xiàng)新發(fā)現(xiàn)可以解釋肥胖者更容易患癌癥的原因。來(lái)自都柏林圣三一學(xué)院的研究團(tuán)隊(duì)發(fā)現(xiàn)，人體用來(lái)破壞癌變組織的一種細(xì)胞會(huì)被過(guò)多的脂肪阻塞，從而停止工作。英國(guó)癌癥研究院（Cancer Research UK）稱，在英國(guó)，肥胖是僅次于吸煙的最大的、可預(yù)防性的致癌因素。

Obesity is the biggest preventable cause of cancer in the UK after smoking. More than one in 20 cancer cases are caused by excess body weight, according to Cancer Research UK. Experts already suspect that fat sends signals to the body that can cause growth and damage to cells, resulting in cancer.
在英國(guó)，肥胖是僅次于吸煙的可預(yù)防的最大致癌因素。據(jù)英國(guó)癌癥研究院統(tǒng)計(jì)，每二十個(gè)癌癥病例中就有超過(guò)一例是因體重超標(biāo)而導(dǎo)致的。專家們已經(jīng)懷疑，由于脂肪會(huì)給人體發(fā)出可造成細(xì)胞增大和損壞的信號(hào)，所以才引發(fā)了癌癥。
Now the team at Trinity have found another pathway that could explain the obesity-cancer link. Too much fat in the body can clog some of the body’s cancer-fighting cells, according to the new work published in Nature Immunology journal.
現(xiàn)在，這支來(lái)自圣三一學(xué)院的研究團(tuán)隊(duì)發(fā)現(xiàn)了另一種可以解釋肥胖與癌癥之間聯(lián)系的方法。他們?cè)凇蹲匀幻庖邔W(xué)》期刊上發(fā)表的新研究稱，體內(nèi)過(guò)多的脂肪可能會(huì)阻塞體內(nèi)的抗癌細(xì)胞。
By doing tests on these ‘natural killer’ cells in their lab, the researchers were able to pinpoint the steps that led to the clogging. Armed with this knowledge, they hope to be able to find drug treatments that could restore the cancer-fighting abilities of natural killer cells.
通過(guò)在實(shí)驗(yàn)室中對(duì)這類 “自然殺傷” 細(xì)胞進(jìn)行測(cè)試，研究人員得以準(zhǔn)確指出造成細(xì)胞堵塞的每一個(gè)階段。認(rèn)識(shí)到了這一點(diǎn)以后，他們希望能找到可恢復(fù)這類自然殺傷細(xì)胞抗癌能力的藥物療法。

3. 答案
1. What is the biggest preventable cause of cancer in the UK?
The biggest preventable cause of cancer in the UK is smoking.
2. How have the team at Trinity explained the obesity-cancer link?
The team at Trinity have explained in their new work published in the Nature Immunology journal that too much fat in the body can clog some of the body’s cancer-fighting cells.
3. True or false? According to Cancer Research UK, more than 5% of cancer cases are caused by being overweight.
True. The text says that according to Cancer Research UK, more than ‘one in twenty’, which means 5%, of cancer cases are caused by excess body weight.
4. Which word in the text means ‘to bring back something to its former condition’?
Restore.
