Biological Function of Rab11-Family Interacting Protein 4 in the Development of Preeclampsia and Their Underlying Mechanism

Abstract

To elucidate the biological function of Rab11-FIP4 in the development of preeclampsia, as well as its clinical significance and underlying mechanism. Relative levels of Rab11-FIP4, IL-6 and TNF-α in placental tissues of PE pregnant women and healthy pregnant women were detected by qRT-PCR. The correlation between Rab11-FIP4 and IL-6 or TNF-α was assessed by Pearson correlation test. After constructing overexpression lentivirus targeting Rab11-FIP4, its influences on biological characteristics of HTR-8/SVneo cells and expression levels of inflammatory cytokines were examined. Rab11-FIP4 was highly expressed in placental tissues of PE pregnant women. Overexpression of Rab11-FIP4 enhanced migratory and invasive capacities of trophoblasts, and upregulated inflammatory proteins. Rab11-FIP4 aggravates the development of PE by upregulating inflammatory proteins, and stimulating migratory and invasive capacities of trophoblasts.
