Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour.
The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science. Scientists have changed the colour of a dark-striped zebrafish to uniform gold by inserting a version of the pigment(色素) gene into a young fish. As with humans, zebrafish skin colour is determined by pigment cells, which contain melanosomes(黑色素). The number, size and darkness of melanosomes per pigment cell determines skin colour.
It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation(变异) in the gene for melanosome production. This results in less pigmented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is dif ferent in human and zebrafish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun(太阳光紫外线), which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vit amin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they pr obably acquired their light skin through the action of some other gene that affects skin colour, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment did on Michael Jackson.

人们可以不用遭受流行音乐之王-迈克尔 杰克孙那样的痛苦而改变皮肤的颜色吗?或许可以.科学家们已经找到了能决定肤色的这种基因.
宾夕法尼亚州立大学的相关研究人员在《科学》上指出,这种基因来自于两个版本,其中一个可以再99%的欧洲人身上看到,另一个则在93%到100%的印度人看上体现出来,科学家把其中一种含有色素的基因注入一条小斑马鱼体内,从而把这条深色条纹的斑马鱼变成了金色.和人类一样的是,斑马鱼的肤色是由其体内色素细胞决定的,黑色素就在其中.每个色素细胞中黑色素的多少,大小以及明暗决定着皮肤的颜色.
显而易见的是,浅肤色的欧洲人和金斑马鱼类似,也是因为产生黑色素的基因发生了变异,从而使皮肤中的色素减少.
然而,研究小组的负责人程凯斯指出,人类的基因和斑马鱼的基因所发生的变异有所不同.
在非洲,大约150万年前,非洲人形成了黑色皮肤,以此使皮肤免受太阳光紫外线的伤害,因为紫外线照射能引发皮肤癌.
但是,当近代人离开非洲,居住在北纬的时候,他们需要的是更多的阳光照耀,以便增加自身的维生素D.所以正如陈所说,相关的基因也有所不同.
陈说:“如非洲人一样,亚洲人也有着同样的肤色基因版本,所以他们在其它肤色基因能影响肤色的前提下,尽可能的让自己的肤色变浅.
这个新发现对医学上治疗皮肤癌有很大的帮助.与此同时,它也促进着越来越多的人研究改变肤色的方法,但不会像迈克尔 杰克逊那样遭受化学药品给他带来的痛苦.
亲,一定要参考采纳,这是我花了2小时翻译出来的,

人们可以改变他们的皮肤颜色不喜欢流行天王迈克尔·杰克逊的痛苦?也许是的。科学家发现基因决定着皮肤的颜色。该基因有两个版本,一个在百分99的欧洲人发现。二是发现在93到100个百分点的非洲人,在科学的最新一期报告宾夕法尼亚州立大学的研究人员。科学家们改变暗条纹的斑马鱼的颜色统一金通过注射一种色素(色素)基因为一位年轻的鱼。作为人类,斑马鱼皮肤颜色的色素细胞决定的,它含有黑色素(黑色素)。的数量,大小...

人们可以改变他们的皮肤颜色不喜欢流行天王迈克尔·杰克逊的痛苦?也许是的。科学家发现基因决定着皮肤的颜色。该基因有两个版本,一个在百分99的欧洲人发现。二是发现在93到100个百分点的非洲人,在科学的最新一期报告宾夕法尼亚州立大学的研究人员。科学家们改变暗条纹的斑马鱼的颜色统一金通过注射一种色素(色素)基因为一位年轻的鱼。作为人类,斑马鱼皮肤颜色的色素细胞决定的,它含有黑色素(黑色素)。的数量,大小和色素细胞的黑素体每黑暗决定了皮肤的颜色。看来,像金色的斑马鱼,浅肤色的欧洲人也有一个突变(变异)基因中的黑素体的生产。这个结果使皮肤中的色素减少。然而,基思程,研究小组的组长,指出突变是不同的人类和斑马鱼的基因。人类获得性皮肤黝黑的大约1500000年前在非洲免受紫外线的太阳(太阳光紫外线),这会导致皮肤癌。但当现代人类离开非洲生活在北半球,他们需要在他们的皮肤产生维生素D.阿明,相关基因的变化,更多的阳光,照成。亚洲人和非洲人的基因相同的版本,所以他们可能获得他们的光PR皮肤通过其他一些基因影响了皮肤的颜色,他说这个行动程。新的发现可能导致皮肤癌的治疗。它也可能导致在改变皮肤的颜色而不破坏它的化学治疗并对迈克尔·杰克逊方法的研究。 希望对你有帮助
