不过Szyf博士还想知道是什么把表现遗传与母性关怀联系起来。
But Dr Szyf still wanted to know what triggers epigenetic tagging in response to maternal care.
拉辛格更应该担忧的应该是年纪更轻的受害者们,他们更需要母性关怀。
Ratzinger should have been more alarmed by the young age of the priest's victims; that's what maternal care would have entailed.
Szyf博士认为,受母性关怀影响的表现遗传性变化出现在出生后的第一周,那是所谓的关键时期。
According to Dr Szyf, epigenetic modifications in response to maternal care occur during the first week of life after birth—the so-called critical period.
对这个的一个解释是在人类这样需要有大量的母性关怀的动物中,女性认为身体上的攻击性是很难承担的。
One idea to explain this is that in animals such as humans, where there is a lot of maternal care, females find physical aggression less affordable.
而这个反馈系统在那些缺少母性关怀的老鼠中被弱化了,使他们更焦虑和恐惧,并且对压力的反应更强烈。
This feedback system is weaker in rats that have had little maternal care. As a result, they are more anxious and fearful, and show a heightened response to stress.
Szyf发现鼠仔接受的母性关怀越多,与糖皮质激素受体基因结合的NGFI -A就越多。这证实了他的猜想。
This suspicion was confirmed when he found it is also the case that the more maternal care a pup receives, the more NGFI-A it has bound to its glucocorticoid-receptor genes.
