OBJECTIVES MUC16 (mucin 16, also known as CA-125, cancer antigen 125, carcinoma antigen 125, or carbohydrate antigen 125) has been predicted as tumor biomarker for therapy. We determined to investigate effects and regulatory mechanism of MUC16 on cervical tumorigenesis. METHODS Expression levels of MUC16 in cervical cancer cell lines was analyzed via qRT-PCR (quantitative real-time polymerase chain reaction). Knockdown of MUC16 was conducted via shRNA (Short hairpin RNA) transfection. MTT and colony formation assays were used to investigate effect of MUC16 on cell proliferation. Wound healing assay was utilized to detect migration and transwell assay to detect invasion. The underlying mechanism was demonstrated via western blot analysis. RESULTS MUC16 was elevated in cervical cancer cell lines. MUC16 knockdown inhibited cell proliferation, invasion and migration. Gain- and loss-of functional assays revealed that over-expression of MUC16 activated Janus Kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) via phosphorylation, thus facilitating cyclooxygenase-2 (COX-2) expression, while knockdown of MUC16 demonstrated the reverse effect on JAK2/STAT3 activation and COX-2 expression. Moreover, inhibition of JAK2/STAT3 attenuated the regulation of MUC16 on COX-2. CONCLUSIONS MUC16 enhanced proliferation and invasion of cervical cancer cells via JAK2/STAT3 phosphorylation-mediated cyclooxygenase-2 expression, suggesting the potential therapeutic target ability of MUC16 to treat cervical cancer.

MUC16通过JAK2 / STAT3磷酸化介导的环氧合酶2表达促进宫颈癌的进展。

目的MUC16(粘蛋白16,也称为CA-125,癌抗原125,癌抗原125或碳水化合物抗原125)已被预测为治疗的肿瘤生物标志物。我们决心调查MUC16对宫颈肿瘤发生的作用和调控机制。方法通过实时定量聚合酶链反应(qRT-PCR)分析MUC16在宫颈癌细胞系中的表达水平。通过shRNA(短发夹RNA)转染进行MUC16的敲除。使用MTT和集落形成测定法来研究MUC16对细胞增殖的影响。伤口愈合测定用于检测迁移,而transwell测定用于检测侵袭。通过蛋白质印迹分析证明了潜在的机制。结果MUC16在宫颈癌细胞系中升高。MUC16组合式抑制细胞增殖,入侵和迁移。功能获得和丧失的测定表明,MUC16的过表达通过磷酸化激活了Janus Kinase 2(JAK2)/信号转导子和转录激活子(STAT3),从而促进了环氧合酶2(COX-2)的表达,同时降低了敲除MUC16的表达证明了对JAK2 / STAT3激活和COX-2表达的反向作用。此外,JAK2 / STAT3的抑制减弱了MUC16对COX-2的调节。结论MUC16通过JAK2 / STAT3磷酸化介导的环氧合酶2表达增强了宫颈癌细胞的增殖和侵袭能力,提示MUC16可能具有治疗宫颈癌的靶向作用。功能获得和丧失的测定表明,MUC16的过表达通过磷酸化激活了Janus Kinase 2(JAK2)/信号转导子和转录激活子(STAT3),从而促进了环氧合酶2(COX-2)的表达,同时降低了敲除MUC16的表达证明了对JAK2 / STAT3激活和COX-2表达的反向作用。此外,JAK2 / STAT3的抑制减弱了MUC16对COX-2的调节。结论MUC16通过JAK2 / STAT3磷酸化介导的环氧合酶2表达增强了宫颈癌细胞的增殖和侵袭能力,提示MUC16可能具有治疗宫颈癌的靶向作用。功能获得和丧失的测定表明,MUC16的过表达通过磷酸化激活了Janus Kinase 2(JAK2)/信号转导子和转录激活子(STAT3),从而促进了环氧合酶2(COX-2)的表达,同时降低了敲除MUC16的表达证明了对JAK2 / STAT3激活和COX-2表达的反向作用。此外,JAK2 / STAT3的抑制减弱了MUC16对COX-2的调节。结论MUC16通过JAK2 / STAT3磷酸化介导的环氧合酶2表达增强了宫颈癌细胞的增殖和侵袭能力,提示MUC16可能具有治疗宫颈癌的靶向作用。此外,JAK2 / STAT3的抑制减弱了MUC16对COX-2的调节。结论MUC16通过JAK2 / STAT3磷酸化介导的环氧合酶2表达增强了宫颈癌细胞的增殖和侵袭能力,提示MUC16可能具有治疗宫颈癌的靶向作用。此外,JAK2 / STAT3的抑制减弱了MUC16对COX-2的调节。结论MUC16通过JAK2 / STAT3磷酸化介导的环氧合酶2表达增强了宫颈癌细胞的增殖和侵袭能力,提示MUC16可能具有治疗宫颈癌的靶向作用。
