Hypoxia-induced TET1 facilitates trophoblast cell migration and invasion through HIF1α signaling pathway

Abstract Low oxygen is a typical extrinsic factor for the regulation of trophoblast biological function, including cell migration, invasion and proliferation. Ten-eleven translocation methylcytosine dioxygenase 1 (TET1), an enzyme converting 5-methylcytosine (5-mC) to 5-hydroxymethylcytosine (5-hmC)...

Ten-eleven translocation methylcytosine dioxygenase 1 (TET1), an enzyme converting 5-methylcytosine (5-mC) to 5-hydroxymethylcytosine (5-hmC), is transcriptionally activated by hypoxia in cancer cells. Therefore, we focus on the role of TET1 on trophoblast function in a physiologically hypoxic environment (3% oxygen), which is related to early placentation. Here, we found that TET1 was highly expressed in first trimester villi compared with normal term placentas. In vitro, both TET1 mRNA and protein expression levels in JEG3 cells were increased following exposure to 3% oxygen, and the migration and invasion capacities of JEG3 cells were up-regulated. Furthermore, TET1 knockdown decreased the migration, invasion and proliferation of JEG3 cells exposed to 3% oxygen, and the expression of HIF1α and its downstream target genes was also decreased, which was related to hyper-methylation of the HIF1α promoter. Finally, increased HIF1α protein expression reversed the inhibitory effect of TET1 knockdown on the migration and invasion of JEG3 cells exposed to 3% oxygen. These data show that hypoxia-induced TET1 expression facilitates trophoblast cell migration and invasion through the HIF1α signaling pathway, which plays an important role during placentation.Jingping ZhuKai WangTing LiJiayu ChenDandan XieXinwen ChangJulei YaoJinting WuQian ZhouYuanhui JiaTao DuanNature PortfolioarticleMedicineRScienceQENScientific Reports, Vol 7, Iss 1, Pp 1-11 (2017)
