【在生活中學習語言】《中英對照讀新聞》 Experts identify gene linked to transsexuality 專家鑑定出與變性慾有關的基因
◎魏國金

Scientists in Australia said they have identified a gene which may explain why some people are transsexuals .

澳洲科學家指出,他們已鑑定出一種基因,或能解釋為何有些人會是變性人。


In the largest genetic study involving transsexuals to date, researchers in Australia said they found that transexuality may be linked to the androgen receptor (AR) gene -- which is known to modify the effect of the male sex hormone testosterone.

在迄今規模最大的變性人遺傳研究中,澳洲的研究者指出,他們發現變性慾或許與雄激素受體(AR)基因有關—已知該基因能減輕男性荷爾蒙睪丸酮的作用。


"There is a social stigma that transsexualism is simply a lifestyle choice, however our findings support a biological basis of how gender identity develops," said lead researcher Vincent Harley of Monash University’s Prince Henry’s Institute of Medical Research.

「社會上存在著變性慾僅是生活方式的選擇的污名,然而我們的發現卻對性別認同如何發展的生物學基礎,提供了支持,」主要研究人、孟納許大學亨利王子醫學研究所的文森.哈利說。


The scientists collected DNA samples from 112 male-to-female transsexuals and found that they were more likely to have a longer version of the AR gene than another group of 258 non-transsexual men.

科學家蒐集112位男變女的變性人DNA樣本,結果發現他們要比由258名非變性男子組成的另一組,較可能有長版的AR基因。


The researchers said the longer AR variant gene may have resulted in less effective testosterone signalling, a mechanism that masculinizes the brain during early development.

研究人員指出,較長的AR變異基因或許導致睪丸酮訊號的釋放較無力,而睪丸酮的訊號釋放是腦部發育早期時,男性化的機制。


新聞辭典

transsexuality、transsexualism:名詞,指易性癖、變性慾。transsexual當名詞為變性人,也可做形容詞,比如︰a transsexual operation(變性手術)。


to date︰迄今為止。of even date,當天的。例句︰I telephoned your office last Monday morning, and sent my letter of even date that afternoon.(我上週一打電話到你的辦公室,而且當天下午又寄出信。)


masculinize︰動詞,使男性化、使具有男性特徵。masculine指男子的、男子氣概的,比如,masculine pride(男子的驕傲)、a masculine looking woman(男性模樣的女人)。
