The differences in the levels of hk10 and DJ-1 in preoperative serum as well as the expression of ovarian cancer-related proliferation genes and invasion genes in intraoperative lesion tissue were compared between the two groups. Correlation analysis was used to assess the inner link of serum hk10 and DJ-1 levels with tumor malignancy in patients with ovarian cancer.Results: Serum hk10 and DJ-1 levels of ovarian cancer group were higher than those of ovarian cyst group;proliferation genes Clusterin, FUNDC1, AKT, TNFAIP8 and HBXIP mRNA expression in lesion tissues were higher than those of ovarian cyst group;invasion genes Beclin1, BRMS1 and SIRT2 mRNA expression in lesion tissues were lower than those of ovarian cyst group whereas EFEMP1 mRNA expression was higher than that of ovarian cyst group. The Pearson test showed that serum hk10 and DJ-1 levels in ovarian cancer were directly correlated with the expression of proliferation genes and invasion genes. Conclusion: hk10 and DJ-1 are highly expressed in serum of patients with ovarian cancer, and their levels are directly correlated with the proliferation and invasion activity of cancer cells.展开更多
