摘　　要：目的研究核不均一核糖核蛋白F(heterogeneous nuclear ribonucleoproteins F,HNRNPF)在前列腺癌中的表达、临床相关性及其对前列腺癌细胞增殖、迁移和侵袭能力的影响。方法使用TCGA和GEO数据库分析HNRNPF在前列腺癌中的表达特征、免疫浸润特征及其与前列腺癌患者临床病理特征的相关性。使用RNA干扰在前列腺癌细胞PC-3和DU145中沉默HNRNPF基因,使用CCK-8、EdU和集落形成实验检测细胞增殖能力的改变,使用Transwell和划痕愈合实验检测细胞迁移、侵袭能力的改变。结果相比正常前列腺组织,HNRNPF在前列腺癌组织中的表达量显著升高。HNRNPF的表达量与前列腺癌患者的T分期、Gleason评分、前列腺特异性抗原以及多种免疫细胞的浸润水平显著相关。HNRNPF高表达的患者总生存期和疾病特异性生存期较短。沉默HNRNPF基因显著抑制了PC-3和DU145细胞的增殖、迁移、侵袭能力。结论HNRNPF是一个在前列腺癌中高表达的基因,具有显著临床相关性,且能够促进前列腺癌细胞增殖、迁移和侵袭。Objective To investigate the expression and clinical relevance of heterogeneous nuclear ribonucleoproteins F(HNRNPF)in prostate cancer and its effect on the proliferation,migration and invasion of prostate cancer cells.Methods The expression and immune infiltration characteristics of HNRNPF in prostate cancer and its correlation with the clinicopathological characteristics of prostate cancer patients were analyzed using TCGA database and GEO database.The HNRNPF gene was silenced by RNA interference in prostate cancer cell PC-3 and DU145,then the changes in cell proliferation ability was detected by CCK-8,EdU and colony formation assays,and the changes in cell migration and invasion abilities were detected by Transwell and wound-healing assays.Results The expression of HNRNPF was significantly increased in prostate cancer compared with normal prostate tissue and significantly associated with T stage,Gleason score,prostate specific antigen and the infiltration level of multiple immune cells of prostate cancer patients.The prostate cancer patients with high expression of HNRNPF had shorter overall survival and disease-specific survival.HNRNPF silencing decreased the proliferation,migration,and invasion abilities of prostate cancer cells PC-3 and DU145.Conclusion HNRNPF is a gene that is highly expressed in prostate cancer,has significant clinical relevance,and can promote the proliferation,migration,and invasion of prostate cancer cells.
