Mechanism of estrogen downregulating hypoxia⁃inducible factor⁃1α to promote invasion and migration of endometriosis
To explore the roles and regulatory mechanisms of estrogen and hypoxia⁃inducible factor⁃1α(HIF⁃1α) in the invasion and migration of endometriosis lesions.
Methods
2
Endometrial stromal cells (ESCs) were divided into three groups: oe⁃vector group (overexpressing vector plasmid in ESCs)
oe⁃HIF⁃1 group (overexpressing vector plasmid in ESCs)
and oe⁃HIF⁃1α+E
2
group (overexpressing vector plasmid in ESCs and using 17β⁃Estradiol
E
2
). The invasion and migration ability of ESCs were evaluated
as well as the expression levels of epithelial⁃mesenchymal transition (EMT) related molecules E⁃Cadherin and Vimentin were determined.
Results
2
The expression of HIF⁃1α in the oe⁃HIF⁃1α+E
2
group was lower than that in oe⁃HIF⁃1 group and oe⁃vector group
and the expression of HIF⁃1α in oe⁃HIF⁃1 group was the highest (all
P
<
0.05). The invasion and migration ability of oe⁃HIF⁃1α+E
2
group was higher than that of oe⁃HIF⁃1α and oe⁃vector group
but the ability of oe⁃HIF⁃1α group was the lowest (
P
<
0.05). The protein and mRNA levels of E⁃Cadherin in oe⁃HIF⁃1α+E
2
group were higher than those in oe⁃HIF⁃1α and oe⁃vector group
but the levels in oe⁃HIF⁃1α group were lower than those in the oe⁃vector group (
P
<
0.05). The protein and mRNA levels of Vimentin in oe⁃HIF⁃1α+E
2
group were lower than oe⁃HIF⁃1α and oe⁃vector group
but the levels inVimentin in oe⁃HIF⁃1α group were higher than in oe⁃vector group (
P
<
0.05).
Conclusion
2
E
2
may be inhibited by HIF⁃1α to promote the EMT process in ESCs
thereby promoting the invasion and metastasis of ectopic endometrium
HIF⁃1α is expected to become one of the targets for the treatment of endometriosis.
