Objective: To explore the relationship between chemokine axis CXCL12-CXCR4 and the pathogenesis and severity of epithelial ovarian cancer.
Methods: SKOV3 transfected with plasmid, SKOV3 transfected with vector and SKOV3 were cultured in vitro. Methyl thiazolyl tetrazolium (MTT) was used to analyze the effects of different concentrations of CXCL12 on the proliferation, migration and invasion of three cell lines and examine the inhibition of neutralizing CXCR4 antibody or antagonist AMD3100. And the load and weight of acquired tumor were determined at different concentrations of CXCL12.
Results: CXCL12 could promote the proliferation, migration and invasion of SKOV3/CXCR4 cells in a dose-dependent fashion (P < 0.05). The effect on CXCL12 tumorigenesis could be inhibited by neutralizing CXCR4 antibody or antagonist AMD3100 (P < 0.05). Significant differences existed in the mean survival time, load and weight of metastatic tumors among the three nude mice.
Conclusion: A close correlation exists between chemokine axis CXCL12-CXCR4 and the pathogenesis, metastasis of epithelial ovarian cancer. The above axis may be an important pathogenic factor of epithelial ovarian cancer. And the antibody of CXCL12-CXCR4 is probably effective in its management.

Epithelial ovarian cancer (EOC) remains a leading cause of gynecologic cancer mortality. Despite advances in treatment, metastatic progression and resistance to standard therapies significantly worsen patient outcomes. Epithelial-mesenchymal transition (EMT) is a critical process in metastasis, enabling cancer cells to gain invasive and migratory capabilities, often driven by changing miRNA expression involved in the regulation of pathological processes like drug resistance.

Mucinous epithelial ovarian cancer (mEOC) is a rare subtype of epithelial ovarian cancer, characterized by poor responses to standard platinum-based chemotherapy. Polo-like kinase 1 (PLK1) is a key regulator of mitosis and cell cycle progression and its inhibition has been recently identified as a target in mEOC. In this study, we aimed to identify further therapeutic targets in mEOC using a CRISPR/Cas9 library targeting 3015 genes, with and without treatment with onvansertib, a PLK1 inhibitor.

This study aimed to construct a risk score (RS) based on necroptosis-associated genes to predict the prognosis of patients with advanced epithelial ovarian cancer (EOC). EOC data from The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) series 140082 (GSE140082) were used. Based on known necroptosis-associated genes, clustering was performed to identify molecular subtypes of EOC.

Background/objective: Platinum-resistant ovarian cancer (PROC) has limited therapeutic options, and the role of cytoreductive surgery (CRS) in improving survival outcomes remains uncertain. We performed a systematic review to evaluate the oncological benefit of CRS on PROC patients and the associated surgical morbidity and mortality.
Methods: We followed a prospective protocol according to PRISMA guidelines.

Background/objectives: S100A4, a small calcium-binding protein, promotes metastasis in a variety of human malignancies, but little is known about its involvement in ovarian clear cell carcinoma (OCCC). Herein, we characterized the functional role of S100A4 in this tumor type.
Methods: We analyzed immunohistochemical sections from 120 OCCC patients.
