The expressions of CD24, B7-H4 and PCNA have correlations with the occurrence, development, invasion and metastasis of ovarian cancer, and the combined detection may have clinical guiding significance for early diagnosis of ovarian cancer and screening of high-risk patients.
Our findings suggest that CD24 induced the EMT phenomenon in ovarian cancer, and that CD24 amplified cell growth-related intracellular signaling via the PI3K/Akt and MAPK pathways by affecting the EMT signal pathways.
Summing up, in this study, we have demonstrated a negative prognostic significance of a cytoplasmic membranous expression of CD24 in cases of ovarian cancer.
We evaluated CD24 protein expression by immunohistochemistry in 9 normal ovaries and 69 epithelial ovarian tumors (5 adenomas, 8 borderline tumors, and 56 carcinomas) with known follow-up data.
