科研: 憑淚水所含獨特蛋白質測試是否患癌

16-11-2016

眼淚可以被用作檢測乳腺癌？研究人員進行一項奇特的實驗，要求電影院裡看電影看得傷感的觀眾捐出她們的眼淚作研究之用。

約400名新西蘭婦女捐贈了她們的眼淚作科研

她們觀賞電影《布魯克林之戀》(Brooklyn) 期間被收集眼淚樣本

美國 Ascendant Diagnostics（診斷公司）收集這些眼淚樣本, 他們認為眼淚蛋白有助檢測乳腺癌. Ascendant Diagnostics（診斷公司）正在開發一種新的癌症篩選技術.通常，一齣悲傷的電影會導致大量的爆米花消耗和一些沾濕了的面紙。

最近在新西蘭的電影院裡，卻取得了其他成果－在檢測乳腺癌方面的一個潛在性突破。

觀賞電影《布魯克林之戀》(Brooklyn) 的婦女捐贈了她們的眼淚予正在開發一個新的癌症檢測裝置的研究人員。

新西蘭婦女捐贈了他們的眼淚，嘗試和幫助乳腺癌研究。

淚液由Ascendant Diagnostics（診斷公司）收集，他們相信眼淚中的蛋白質可以檢測乳腺癌。

來自美國 Ascendant Diagnostics（診斷公司）的研究人員認為眼淚可能有助檢測乳腺癌，準確度達90％。

「乳腺癌的篩選分析乃基於淚液中發現的一組稱為 Melody 的專有蛋白質。」該公司在一篇研究摘要中解釋。

「採集這種蛋白質可以區分患乳腺癌的女性和沒有患乳腺癌的女性，敏感度達 88％，特異性達 86％。」

目前，乳腺X光造影是檢測乳腺癌最常見的方法，但對於乳房組織密度高的婦女而言，乳腺X光造影並非最有效的檢測方法。

但在尋求法例准許使用之前，科學家需要改進測試設備和收集更多的眼淚。

400名婦女自願參加研究。屏幕上播放《布魯克林之戀》(Brooklyn) 如此一齣催淚電影，要收集她們的眼淚樣本，一點也不難。

Ascendant Diagnostics（診斷公司）希望創建一種能夠更容易地檢測早期乳腺癌的設備。

Could TEARS be used to detect breast cancer? Bizarre experiment sees researchers asking weepy cinema goers to donate theirs to find out

Around 400 New Zealand women have donated their tears to science
They watched the film Brooklyn as their tears were collected
American company Ascendant Diagnostics collected the samples
They believes proteins in tears could help detect breast cancer
The company is working on a new technology for cancer screening

Usually all that comes out of a screening of a sad movie is a lot of popcorn consumed and some soggy tissues.

But at a New Zealand cinema recently, something else was achieved—a potential breakthrough in detecting breast cancer.

Women watching the drama Brooklyn donated their tears to researchers who are developing a new cancer detection device.

The tears were collected by Ascendant Diagnostics Dx, who believe proteins in tears could detect breast cancer

American researchers from company Ascendant Diagnostics (Dx) believe that tears could potentially help breast cancer with 90 per cent accuracy.

'The screening assay for breast cancer is based on a proprietary set of proteins found in tear fluid, called Melody,' the company explains in a research abstract.

'This collection of proteins can distinguish women who have breast cancer from women who do not with sensitivity of 88 per cent and a specificity of 86 per cent.'
