Sci Rep:生男生女大不同,高龄孕妇男性后代心血管疾病风险明显增高!

2019-12-02 Paris 转化医学网

前段时间,67岁高龄孕妇产子的消息席卷全国。在二胎开放的当今,高龄孕妇(我国将年龄大于35岁的孕妇定义为高龄孕妇)愈发普遍,但其实,35岁以上的高龄产妇妊娠风险值呈明显上升趋势,出现难产、胎儿发育迟缓、先天性畸形儿以及孕产妇、胎儿死亡的几率要远远大于年轻产妇。

前段时间,67岁高龄孕妇产子的消息席卷全国。在二胎开放的当今,高龄孕妇(我国将年龄大于35岁的孕妇定义为高龄孕妇)愈发普遍,但其实,35岁以上的高龄产妇妊娠风险值呈明显上升趋势,出现难产、胎儿发育迟缓、先天性畸形儿以及孕产妇、胎儿死亡的几率要远远大于年轻产妇。

近日,一项刊登于Nature子刊Scientific Reports的新研究关于高龄孕妇又有了新见解,动物实验研究发现,大龄孕鼠的胎盘功能会发生改变,这种改变将导致男性后代健康状况恶化的风险升高,尤其在心血管疾病方面,而对女性后代则无明显影响。



为什么会有这种性别差异呢?胎盘功能变化又是如何影响胎儿健康的呢?

胎盘将营养和氧气从母体输送到胎儿,并向母体分泌信号因子。所以她支持胎儿发育,并且是胎儿对母体血液中的毒素、细菌和激素的主要保护屏障——比如压力激素。它具有高度动态的性质,当生长的胎儿的发育条件变得不太有利时,例如由于缺乏营养或氧气,或当母亲受到压力时,它的功能可以改变,以帮助保护生长中的胎儿。然而,与正常孕龄妇女相比,高龄产妇由于胚胎质量或胎盘功能下降以及子宫内环境改变,胎儿各器官发育不成熟风险增加,因而易出现胎儿、新生儿异常。

在本次研究中,研究人员首先进行了以小鼠为对象的动物实验,他们选择了3~4月龄的年轻雌性小鼠(对应年轻产妇)与9~10月龄的高龄雌性小鼠(对应高龄产妇)分别与3~5月龄的年轻雄性小鼠交配,以评估母体年龄的增长对于胎盘和子代小鼠的影响。


年轻与年老孕鼠的胎儿和胎盘重量
 
在对两组小鼠生产的数据进行对比后,研究人员发现,高龄产妇的后代中,雌性与雄性的体重相比年轻产妇都下降了约20%~25%,其中,在雄性子代个体中观察到,体重的减少与脑、肝与心脏的绝对重量减少有关。高龄产妇的胎盘效率(子代体重/胎盘体重)也出现了下降,其中雌性下降约22%,雄性下降约37%。高龄产妇的雌性子代中,胎盘上会产生有益于子代的变化,但是在雄性中却相反,导致心血管疾病等健康问题的风险升高。

相对于年轻(3-4月)孕鼠,高龄孕鼠(9.5-10个月)更易影响胎盘表型性别。具体来讲,年轻母鼠胎盘转运区和内分泌区面积增加,而在高龄孕鼠中,Igf2和胎盘催乳素(Pr3b1:+59)基因在女性胎儿中表达上调,在男性胎儿中不表达。不仅如此,胎盘IGF2蛋白丰度在男性胎儿中下降了。此外,糖皮质激素代谢(11 β -hsd2:+63和11 β -hsd1:- 33)在女性胎儿中较高,在男性胎儿中则较低(11 β -hsd2:-50和11 β -hsd1:未改变)。这一连串的机制产生的结果最终改变了性别特异的胎盘表型。而这些性别差异的变化对胎儿的健康起关键作用。

该研究进一步推动了高龄孕妇的围产期管理,有助于妊娠期合并症及新生儿远期并发症的减少。研究人员将继续在此研究结果的基础上,寻找如何通过改善胎盘优化胎儿的生长发育过程。
