有些小孩偏胖或偏瘦,但基因序列相同。他们对此做了专门研究。小孩一出生他们就抽取血样,并以此作为研究的基础。实验显示,很多后来变胖的小孩,其实刚出生时的基因组印记就已经不同了。
Dr Caroline Relton, who led the research, said: ‘This suggests that our DNA could be marked before birth and these marks could predict our later body composition.’ Dr Relton, whose findings are detailed in the journal PLoS Medicine, does not know why some DNA is marked in the womb。
负责这项研究的卡洛琳·雷尔顿博士说:“实验表明,DNA在子宫里就有所改变了。而这些变化能预测人们日后的体型。” 雷尔顿博士的研究成果已经发表在了PLoS Medicine杂志上。不过,她坦言自己也不清楚为何DNA在子宫里就能发生改变。
But previous research suggests it is largely to do with the mother’s lifestyle. However, Dr Relton added: ‘These marks are open to change. I think this puts the onus on the individual to do something about the way their genes work.’
在此之前,研究认为,这与准妈妈的生活习惯有大有关联。但雷尔顿博士也说:“基因组印记的变化是持续的。出生以后的改变,确实跟个人的生活习惯有关。”
