PROBLEM: Trophoblast cells regulate embryo implantation and placental development. Eukaryotic initiation factor 5A (eIF5A) is an initiator of translation involved in cellular processes, such as migration, proliferation, and apoptosis. However, the function of eIF5A in trophoblast cells is unknown.
METHOD OF STUDY: We inhibited eIF5A and Ca2+ /calmodulin-dependent protein kinase 1D (CAMK1D) expression in HTR8 cells using RNA interference. The effects of eIF5A and CAMK1D on HTR8 cells were investigated using real-time polymerase chain reaction, Western blotting, flow cytometry, cell transfection assays, cell migration assays, and terminal deoxynucleotidyl transferase dUTP nick-end labeling.
RESULTS: eIF5A inhibition decreased CAMK1D expression, proliferation, migration, and invasion, but upregulated apoptosis, in HTR8 cells.
CONCLUSION: Cross-talk between eIF5A and CAMK1D enhances proliferation, migration, and invasion, but inhibits apoptosis, in trophoblasts.
