Expression of the novel gene NM23-H1B in ovarian cancer

摘要

Objective: To study the expression of the human novel gene NM23-H1B in ovarian cancer. Methods: Totally 24 samples from patients with epithelial ovarian tumor at different clinical stages and 4 from normal ovaries were examined for NM23-H1B mRNA expression by RT-PCR and Northern blot. Results : All samples expressed NM23-H1B mRNA through RT-PCR, while the level of expression in ovarian tumor was higher than that of normal ovary. The results of Northern blot showed that NM23-H1B was overexpressed in ovarian cancer while lowexpressed in normal ovary or low malignant potential (LMP). The level of expression at early stage cancer (stage Ⅰ and Ⅱ ) was higher than those in advanced cancer (stage Ⅲ and Ⅳ ). In early stage carcinoma, the expression level was involved in the differentiation of tumor cell, and well-differentiated cancer expressed NM23-H1B mRNA in comparatively higher level. Conclusion; The novel gene NM23-N1B is closely correlated with the ovarian cancer.
