问题I 型干扰素 (IFN)、IFN-tau (τ) 是反刍动物妊娠维持的主要胚胎信号。本研究确定了体外热休克对牛囊胚 IFN-τ (IFNT) 基因表达的影响。研究方法将体外产生的囊胚期胚胎暴露于 42°C 4 小时,并对热休克蛋白 70 (HSP70) 和 IFNT 的 mRNA 进行定量。结果热休克增加了 HSP70 和 IFNT 的表达。无论囊胚是否暴露于热休克,HSP70 和 IFNT 转录水平之间都存在显着相关性。结论 热休克导致 IFNTa 增加,表明在囊胚期胚胎中观察到的 IFNT 表达变化的一部分是对应激的反应。
ProblemThe type I interferon (IFN), IFN‐tau (τ), is the primary embryonic signal for pregnancy maintenance in ruminants. This study determined the effects of heat shock upon IFN‐τ (IFNT) gene expression by bovine blastocystsin vitro.Method of studyIn vitro‐produced blastocyst‐stage embryos were exposed to 42°C for 4 hr, and mRNA for heat‐shock protein 70 (HSP70) andIFNTquantified.ResultsHeat shock increased bothHSP70andIFNTexpression. There was a significant correlation betweenHSP70andIFNTtranscript levels irrespective of whether a blastocyst had been exposed to heat shock or not.ConclusionThe increase inIFNTas a result of heat shock suggests that a proportion of the variation inIFNTexpression observed in blastocyst‐stage embryos is a response to stress.
