背景

血管紧张素I(Ang I)化学式为C62H89N17O14,多肽序列为H-Asp-Arg-Val-Tyr-Ile-His-Pro-Phe-His-Leu-OH ,是通过肾素对血管紧张素的作用形成的。肾素在肾脏中产生,肾脏响应肾交感神经活动,减少肾小球旁细胞中肾内血压(收缩压小于90mmHg),从而产生肾素。Ang I似乎没有生物活性,仅仅是作为血管紧张素II(AII)的前体物质。在血管紧张素转换酶(ACE)作用下,血管紧张素I转变为血管紧张素Ⅱ。在血管平滑肌细胞中,血管紧张素Ⅱ通过刺激Gq蛋白增加血压,最终通过IP3依赖机制激活血管收缩。

试验操作

Animal experiment:[1]

Animal models

Time-dated pregnant ewes (gestational day 125 ± 5, term ~ 145 days)

Dosage form

5 μg/kg

Intracerebroventricular injection

Applications

Intracerebroventricular injection of Ang I significantly increased fetal blood pressure and c-fos expression in the supraoptic nuclei (SON) and the paraventricular nuclei (PVN) in the hypothalamus, accompanied by an increase of fetal plasma arginine vasopressin (AVP). Double labeling experiments showed colocalization of AT1 receptor and c-fos expression in both SON and PVN following Ang I treatment. The results indicate that central angiotensin I increases fetal AVP neuron activity and pressor responses.
