ABSTRACT: Purpose
Uterine serous carcinoma (USC) is a highly aggressive and frequently recurring subtype of endometrial cancer with limited treatment options for advanced or recurrent stages. Sulindac, a classic non-steroidal anti-inflammatory drug, has demonstrated anti-tumor activity in several pre-clinical tumor models. This study aims to evaluate the effect of sulindac on cell proliferation and invasion in USC cells.Methods
Human USC cell lines ARK-1 and SPEC2 were treated with different concentrations of sulindac. Cell proliferation was assessed using MTT and colony formation assays. ELISA assays measured cellular stress, cleaved caspase 3 activity, antioxidant ability, and adhesion. Cell cycle arrest was evaluated by Cellometer. The invasive capability was detected by wound healing assay. Western blotting was used to analyze the changes in protein expression induced by sulindac.Results
Exposure to sulindac decreased cellular viability in a dose-dependent manner in ARK-1 and SPEC2 cells. Sulindac effectively inhibited cell cycle progression, increased cellular stress, caused apoptosis, and reduced cell adhesion and invasion in USC cells. Additionally, sulindac decreased the expression of COX-2 and blocked phosphorylation of NF-κB induced by TNF-α.Conclusion
Sulindac is a potential therapeutic agent for USC that deserves further exploration in pre-clinical studies and potentially future clinical trials.
