摘要：Objectives: To investigate the effects of the human chromosomal segregation 1-like (CSE1L) gene on the biological behaviour of human placental cells. Study design: The CSE1L gene plays important roles in chromosome segregation during mitosis, cell proliferation and apoptosis. We used MTT, Cellomics, cell colony formation and flow cytometry assays in this study. Results: CSE1L mRNA was significantly increased in human placental cells (JAR) and decreased when CSE1L was knocked down. Lentiviral CSE1L knockdown reduced cell proliferation (p < .05) and colony formation (p = .00) and induced apoptosis (p < .000). CSE1L knockdown inhibited the G0/G1 phase (p = .00) and increased the G2/M phase (p = .00) of the cell cycle, but no significant change in the S phase was observed (p = .158). Conclusion: The CSE1L protein is expressed in human placental carcinoma cells, and its knockdown altered biological behaviours, implying that the CSE1L gene may affect human placental formation and even foetal development.
