| 摘 要： | 目的 探究 DR-NM23在卵巢癌组织中的表达及对细胞增殖和转移的影响。方法 收集卵巢癌肿瘤组织和癌旁组织各 68例，通过免疫组化染色检测 DR-NM23表达水平，分析绝经、肿瘤大小、分化程度、局部浸润、淋巴转移和远端转移与 DR-NM23表达水平的相关性。在 SKOV3细胞系中过表达、沉默 DR-NM23，分别得到 DR-NM23组和 SiDR-NM23组，与对照组（ NC组）相比，评估各组增殖、迁移和侵袭能力，以评估 DR-NM23在卵巢癌组织中的作用机制。结果 卵巢癌组织中 DR-NM23平均染色强度为 2.68±0.75，低于癌旁组织 7.05±2.05，差异具有统计学意义（ P<0.05）。卵巢癌组织中 DR-NM23表达水平与是否绝经、肿瘤大小以及局部浸润无相关性，差异均无统计学意义（ χ2=0.418, 0.864,

| Abstract: | Objective To explore the expression of DR-NM23 in ovarian cancer and its effect on cell proliferation andmetastasis. Methods 68 cases of ovarian cancer tissues and adjacent tissues were collected clinically, and the DR-NM23expression level was detected by immunohistochemistry, and the correlation of DR-NM23 expression level with menopause,tumor size, differentiation, local invasion, lymph node metastasis and distal metastasis was analyzed. Overexpression andsilencing of DR-NM23 in SKOV3 cell line were used to obtain DR-NM23 group and Si-NM23 group, respectively. Comparedwith the control group (NC group), the proliferation, migration and invasion ability of each group were evaluated for themechanism of DR-NM23 in ovarian cancer tissue. Results The average staining intensity of DR-NM23 in ovarian cancer tissuewas (2.68±0.75), which was lower than that in adjacent tissues (7.05±2.05) with stastically significant difference (P<0.05).Whether there was no correlation in menopause, tumor size and local invasion with the expression level of DR-NM23 in ovariancancer tissue, the differences not were statistically significant（χ2=0.418, 0.864, 2.915, all P>0.05）. The expression level ofDR-NM23 was lower in tissues with poor differentiation, lymph node metastasis and distant metastasis, the differences werestatistically significant (χ2=6.678, 6.845, 8.215, all P<0.05). The CCK-8 absorbance (1.16±0.18), migration distance percentage(88.58%±5.48%) and invasive cells (207.26±13.52) of siDR-NM23 group was higher than that of NC group(0.68±0.11,62.34%±2.15%, 125.54±8.15), while DR-NM23 group(0.47±0.07, 45.12%±3.76%, 59.57±5.02) was lower than that of NCgroup, the differences were stastically significant (all P<0.05). Conclusion DR-NM23 was lowly expressed in ovarian cancertissue, might has the effect of inhibiting the proliferation, migration and invasion of tumor cells. |
