Hypothesis
A proposed mechanism for progesterone regulation of trophoblast MMP2 transcription independent of classical progesterone response elements on its promoter.
Conclusion
Progesterone can regulate MMP2 expression in trophoblasts through mechanisms that do not rely on classical response elements.
Supporting Evidence
- Progesterone inhibits MMP2 expression in early trophoblast cells.
- PR-B is dominant in early trophoblast, while PR-A is dominant in late trophoblast.
- Progesterone can regulate genes lacking classical response elements.
Takeaway
This study suggests that progesterone can help control certain genes even when they don't have the usual markers that tell cells to respond to it.
Methodology
The study involved transient transfection of mutated or deleted constructs of the human MMP promoter into trophoblast cells to assess progesterone's regulatory effects.
