title: Cellular Localization and Regulation of Expression of the PLET1 Gene in Porcine Placenta.
abstract: The placenta expressed transcript 1 (PLET1) gene, which is expressed in placentas of pigs and mice, has been found to have a potential role in trophoblast cell fate decision in mice. Results of this study showed that the porcine PLET1 mRNA and protein were expressed exclusively in trophoblast cells on Days 15, 26, 50, and 95 of gestation (gestation length in the pig is 114 days), indicating that the PLET1 could be a useful marker for porcine trophoblast cells. Additionally, PLET1 protein was found to be redistributed from cytoplasm to the apical side of trophoblast cells as gestation progresses, which suggests a role of PLET1 in the establishment of a stable trophoblast and endometrial epithelial layers. In addition, two transcripts that differ in the 3' UTR length but encode identical protein were identified to be generated by the alternative cleavage and polyadenylation (APA), and the expression ofPLET1-Ltranscript was significantly upregulated in porcine placentas as gestation progresses. Furthermore, we demonstrated the interaction between the miR-365-3p andPLET1gene using luciferase assay system. Our findings imply an important role of PLET1 in the placental development in pigs.
