This article looks into the process of embryo implantation. It demonstrates how the activation of the epithelial Na(+) channel triggers prostoglandin E(2) release,phosphorylation of teh transcription factor CREB and upregulation of cyclooxygenase 2, the enzyme required for prostaglandin production and implantation. They detected maximum Epithelial Na(+) channel activation at the time of implantation in mice, and that blocking or knocking down this channel in mice resulted in failure to implant. These results indicate the importance of the Epithelial Na(+) Channel in the process of implantation, and the consequences of defects such as miscarriage and low success rates in IVF.
