A lentiviral vector was used to produce non-human animals that express human sFLT1 specifically in the murine placenta, to provide model animals of diseases such as pregnancy-induced hypertension syndrome that are close to the clinical conditions, methods for producing the model animals, methods of screening for candidate compounds as therapeutic agents for diseases such as pregnancy-induced hypertension syndrome by using the model animals, and therapeutic agents for diseases such as pregnancy-induced hypertension syndrome. As a result, the model animals were found to exhibit symptoms that are very close to the clinical conditions in human, which are presentation of hypertension as well as placental insufficiency, intrauterine growth retardation, glomerulosclerosis, and proteinuria during pregnancy, and improvement of those symptoms postpartum. Furthermore, when pravastatin was administered to this model animal, it was found that diseases such as pregnancy-induced hypertension syndrome were improved by the activation of placenta-derived growth factor (PIGF) which antagonizes sFLT1.
使用了一个lentiviral载体来产生非人类动物,这些动物在小鼠胎盘中特异性地表达人类sFLT1,以提供近似于临床情况的妊娠诱发高血压综合症等疾病的模型动物,以及制备该模型动物的方法,利用该模型动物筛选候选化合物作为治疗妊娠诱发高血压综合症等疾病的治疗剂的方法,以及用于治疗妊娠诱发高血压综合症等疾病的治疗剂。结果发现,模型动物表现出与人类临床情况非常接近的症状,包括妊娠期高血压、胎盘功能不全、胎儿宫内生长迟缓、肾小球硬化和蛋白尿,以及产后这些症状的改善。此外,当普伐他汀被用于该模型动物时,发现通过激活胎盘源性生长因子(PIGF)来对抗sFLT1可以改善妊娠诱发高血压综合症等疾病。
