Abstract

OBJECTIVE
Granulocyte-macrophage colony-stimulating factor (GM-CSF) facilitates mammalian embryonic development and implantation. However, its biological function after implantation is not elucidated. The aim of this study is to assess the changes of gene expression by GM-CSF in human trophoblast obtained in early pregnancy. METHODS: Human trophoblast obtained in early pregnancy was cultured with or without GM-CSF. The difference of gene expression was evaluated with microarray and selected genes were reevaluated with real-time reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: Microarray analysis revealed that the expressions of 468 genes were increased while those of 40 genes were decreased by GM-CSF. These genes were evaluated according to the known biologic pathways. The regulation of actin cytoskeleton and focal adhesion pathways were mostly influenced by GM-CSF. Annexin A2, thymosin-like 3, vimentin, myogenin, ACK1, and tensin1 genes were selected for real-time RT-PCR. The increased expressions of of vimentin and ACK1, and decreased expressions of tensin1 were confirmed by real-time RT-PCR. CONCLUSION: GM-CSF activates focal adhesion pathway in human trophoblast by increasing the expression of vimentin and ACK1, and decreasing the expression of tensin1.
