To explore the relationship between chemokine axis CXCL12-CXCR4 and the pathogenesis and severity of epithelial ovarian cancer.
SKOV3 transfected with plasmid, SKOV3 transfected with vector and SKOV3 were cultured in vitro. Methyl thiazolyl tetrazolium (MTT) was used to analyze the effects of different concentrations of CXCL12 on the proliferation, migration and invasion of three cell lines and examine the inhibition of neutralizing CXCR4 antibody or antagonist AMD3100. And the load and weight of acquired tumor were determined at different concentrations of CXCL12.
CXCL12 could promote the proliferation, migration and invasion of SKOV3/CXCR4 cells in a dose-dependent fashion (P < 0.05). The effect on CXCL12 tumorigenesis could be inhibited by neutralizing CXCR4 antibody or antagonist AMD3100 (P < 0.05). Significant differences existed in the mean survival time, load and weight of metastatic tumors among the three nude mice.
A close correlation exists between chemokine axis CXCL12-CXCR4 and the pathogenesis, metastasis of epithelial ovarian cancer. The above axis may be an important pathogenic factor of epithelial ovarian cancer. And the antibody of CXCL12-CXCR4 is probably effective in its management.
探讨趋化因子轴CXCL12 - CXCR4与上皮性卵巢癌的发病机制及严重程度之间的关系。
体外培养质粒转染的SKOV3细胞、载体转染的SKOV3细胞和SKOV3细胞。采用甲基噻唑基四氮唑(MTT)分析法分析不同浓度的CXCL12对三种细胞系增殖、迁移和侵袭的影响,并检测中和CXCR4抗体或拮抗剂AMD3100的抑制作用。同时测定不同浓度CXCL12作用下荷瘤的负荷及重量。
CXCL12能以剂量依赖方式促进SKOV3/CXCR4细胞的增殖、迁移和侵袭(P < 0.05)。中和CXCR4抗体或拮抗剂AMD3100可抑制CXCL12对肿瘤发生的作用(P < 0.05)。三只裸鼠转移性肿瘤的平均生存时间、负荷及重量存在显著差异。
趋化因子轴CXCL12 - CXCR4与上皮性卵巢癌的发病机制、转移密切相关。上述轴可能是上皮性卵巢癌的重要致病因素。并且CXCL12 - CXCR4抗体可能对其治疗有效。
