Functional regulation of human trophoblast cells by CSE1L

Abstract

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.
