Abstract

Preeclampsia, a relatively common pregnancy disorder, is a major contributor to maternal mortality and morbidity worldwide. An elevation in microRNA-210 (miR-210) expression in the placenta has been reported to be associated with preeclampsia. Our bioinformatic analysis showed that thrombospondin type I domain containing 7A (THSD7A) is a predicted target for miR-210. The aim of this study was to determine whether miR-210 is involved in preeclampsia through its targeting of THSD7A in human placental trophoblasts. In preeclamptic placental tissues, THSD7A levels were significantly downregulated and were inversely correlated with the levels of miR-210. THSD7A was validated as a direct target of miR-210 using quantitative real time PCR (qRT-PCR), Western blotting and dual luciferase assays in HTR8/SVneo cells. Transwell insert invasion assays showed that THSD7A mediated the invasion-inhibitory effect of miR-210 in HTR8/SVneo cells. Interestingly, hypoxia markedly increased miR-210 expression while suppressing THSD7A expression in a time-dependent manner in HTR8/SVneo cells. This study provides novel data on the function of THSD7A in human placental cells and extends our knowledge of how miR-210 is involved in the development of the preeclampsia.

  • Other targets identified for miR-210 include the steroidogenic enzyme hydroxysteroid (17-ß) dehydrogenase 1, ephrin-A3 and homeobox-A9 which are involved in trophoblast cell migration and vascular remodeling, and thrombospondin type 1 domain containing 7A in the placental vasculature.

    “Besides mitochondria, other targets identified for miR-210 include the steroidogenic enzyme hydroxysteroid (17-ß) dehydrogenase 1 (272), ephrin-A3 and homeobox-A9 which are involved in trophoblast cell migration and vascular remodeling (611), and thrombospondin type 1 domain containing 7A in the placental vasculature (351).”

  • MiR-210 is increased in normal placentas from pregnancies at high altitude, and in placentas from pregnancies complicated by pre-eclampsia.

    “It is increased in normal placentas from pregnancies at high altitude (121), and in placentas from pregnancies complicated by pre-eclampsia (272, 351, 401, 611).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
