Abstract

Background

Glycogen synthase kinase-3β (GSK-3β) is a multifunctional serine/threonine kinase that plays an important role in cancer tumorigenesis and progression. We investigated the role of the GSK-3β inhibitor AZD1080 in ovarian cancer cell lines.

Methods

A2780 and OVCAR3 ovarian cancer cell lines were exposed to AZD1080, after which cell proliferation, cell cycle, invasion, and migration assays were performed. Phalloidin staining was used to observe lamellipodia formation. Reverse transcription polymerase chain reaction and Western blot were used to assess the respective mRNA and protein expression levels of GSK-3β, CDK2, CDK1, cyclin D1, matrix metalloproteinase-9 (MMP9), and Bcl-xL.

Results

AZD1080 exposure suppressed ovarian cancer cell proliferation, invasion, migration, and lamellipodia formation, and induced G1 arrest, which was concentration dependent. AZD1080 also significantly downregulated GSK-3β, CDK2, CDK1, cyclin D1, MMP9, and Bcl-xL expression at both mRNA and protein levels.

Conclusion

Taken together, our results demonstrate that the GSK-3β inhibitor AZD1080 suppresses ovarian cancer development and therefore may indicate a new direction for ovarian cancer treatment.
