The role of the REG4 gene and its encoding product in ovarian epithelial carcinoma
BMC cancer · Jun 2015 · cell line experiments plus human tissue expression and survival analysis
This study looked at REG4 in ovarian epithelial carcinoma using SKOV3 cells and ovarian tissue samples. In cells, adding REG4 or making cells overexpress REG4 reduced apoptosis and increased proliferation, migration, invasion, and G2/S cell-cycle progression. In patient tissues, REG4 was more highly expressed in tumor samples than in normal ovarian tissue, and higher REG4 expression was linked with worse survival outcomes.
Key findings
- REG4 overexpression and recombinant REG4 inhibited apoptosis in SKOV3 cells.
- REG4 increased proliferation, migration, invasion, and G2/S progression in SKOV3 cells.
- Wnt5a, p70s6k, survivin, and VEGF increased, while Bax decreased with REG4 overexpression.
- REG4 mRNA and protein were higher in ovarian tumor tissues than in normal ovarian tissue.
- Higher REG4 expression was associated with poorer cumulative and relapse-free survival.
REG4 was studied as a biomarker and functional regulator in ovarian cancer, not as a repurposed drug or natural compound.
