BACKGROUND/AIM: Mucinous ovarian carcinoma (mOC) is a rare subtype with distinct clinical characteristics and biological behavior that differentiate them from other epithelial ovarian cancers. This study aimed to evaluate BMI-1 expression as a potential target for therapeutic approaches in advanced stage mOC.
MATERIALS AND METHODS: We performed gene set, as well as transcription factor enrichment analysis and immunohistochemistry assessing of the BMI-1 protein levels in tissue specimens of eighteen mucinous ovarian cancer patients. To validate the clinical relevance of the findings, we performed cell viability assays and western blot analysis utilizing high-grade serous (HGSC) and mOC cell lines.
RESULTS: BMI1 expression was not significantly associated with patient age, FIGO stage, lymph node status, and family history. With regard to progression-free survival, there was also no significant association (p=0.418). Cell viability was significant decreased in response to carboplatin in HGSC cells TYK-nu and OVHASO, and in mOC cell lines COV644 and EFO-27. Western blot analysis demonstrated various expression levels across all cell lines.
CONCLUSION: BMI-1 could be a useful potential therapeutic target in some ovarian cancer patients, including mOC patients.
