miR-155 suppresses angiotensin II type 1 receptor synthesis during placental morphogenesis (opens in new tab)

Several microRNAs play vital roles in placental development. miR-155 has been implicated in placental development and can directly interact with a variety of targets, including angiotensin type II receptor 1 (AT1R) (Agtr1) mRNA. The AT1R is pro-proliferative and promotes early placental development. We therefore tested the hypothesis that miR-155 downregulates Agtr1 mRNA expression and impairs placental development. Placentae and fetuses from wild-type C57Bl/6 mice (miR-155+/+, control) and C...
