RESUMEN
Objective To study the expression of hypermethylated gene 1 protein and ovarian cancer gene 1 protein in ovarian cancer and its relationship with the pathological features of ovarian cancer,and to explore its significance in ovarian cancer.Methods Sixty-three cases of ovarian cancer specimens and 63 cases of normal ovarian tissue were taken from January 2014 to December 2015 at the First Hospital of Jilin University.Western blot was used to detect the expression of hypermethylated gene 1 protein and ovarian cancer gene 1 protein in ovarian cancer tissues and normal ovarian tissues,and to analyze the relationship between the expression of two proteins and ovarian cancer.Results The expression of hypermethylated gene 1 protein and ovarian cancer gene 1 protein in ovarian cancer tissues were significantly lower than that in normal ovarian tissues (P＜0.05).There was no significant difference in the expression of hypermethylated gene 1 protein in different staging,different degree of differentiation and different pathological types in ovarian cancer (P＞0.05).The expression of ovarian cancer gene 1 protein in ovarian cancer stage Ⅰ was higher than that in stage Ⅱ and Ⅲ-Ⅳ (P＜0.05).The expression of ovarian cancer gene 1 protein in ovarian cancer stage Ⅱ was higher than that in stage Ⅲ-Ⅳ (P＜0.05).The expression of ovarian cancer gene 1 protein in high differentiation of ovarian cancer was significantly higher than that in moderately differentiated and poorly differentiated (P＜0.05).There was no significant difference between ovarian cancer gene 1 protein expression and poorly differentiated ovarian cancer (P＞0.05).There was no sig nificant difference in the expression of ovarian cancer gene 1 protein in different pathological types of ovarian cancer (P＞0.05).Conclusion Hypermethylatel gene,protein participate in the occurrence of ovarian cancer,the ovarian cancer gene 1 protein is only related to ovarian cancer clinical stage and degree of differentiation.
