摘要

目的探讨人卵巢癌干细胞（ovarian cancer stem cells，OCSCs）自分泌趋化因子CXCL16对OCSCs增殖及侵袭迁移能力的影响。方法采用Real-time PCR、ELISA及流式细胞仪检测A2780细胞株诱导的CD133

非卵巢癌干细胞（non ovarian cancer stem cells，nOCSCs）中CXCL16及CXCR6的表达；用CCK-8法检测阻断CXCL16对OCSCs增殖能力的影响；利用Transwell迁移、侵袭实验检测分别阻断CXCL16或CXCR6及shRNA沉默CXCL16对OCSCs侵袭迁移能力的影响。结果与nOCSCs比较，OCSCs中CXCL16及CXCR6 mRNA均表达上调（P0.01）。ELISA结果显示OCSCs 的CXCL16分泌量远远高于nOCSCs[（2 434.00±204.65）vs （129.33±31.64）ng/mL

non-ovarian cancer stem cells (nOCSCs) was detected by real-time PCR

enzyme linked immunosorbent assay and flow cytometry. CCK-8 assay was used to assess the effect of CXCL16 on proliferation of OCSCs. Transwell migration assay and Matrigel invasion assay were used to determine invasion and migration ability of OCSCs after blocking CXCL16 or CXCR6 with neutralizing antibody or short hairpin RNA (shRNA). Results Compared with nOCSCs

CXCL16 and CXCR6 at mRNA expression level were increased in OCSCs (P0.01). OCSCs had more CXCL16 secretion (2 434.00±204.65 ng/mL) than nOCSCs (129.33±31.64 ng/mL) (P0.01). And the CXCR6 expression in OCSCs (60.6%) was higher than that in nOCSCs (2.4%) (P0.01). CCK-8 assay showed that the proliferation of OCSCs was not affected after blocking CXCL16 with neutralizing antibody (P0.05). When CXCL16 or CXCR6 was blocked with neutralizing antibody

OCSCs showed decrease of invasion and migration ability (P0.01). Invasion and migration ability of OCSCs was also significantly inhibited when blocking CXCL16 with shRNA (P0.01). Conclusion Autocrine chemokine CXCL16 can bind to CXCR6 to maintain high ability of invasion and migration of CD133

OCSCs.
