Sci Rep:转移前列腺癌中HOXB13同源异型盒基因能够调控有丝分裂蛋白激酶互作网络

2019-07-21 AlexYang MedSci原创

HOXB13是一个同源异型盒转录因子,并且与根治性前列腺切除术后复发有关。虽然HOXB13能够以环境依赖的方式来调控雄激素受体(AR)功能,它在前列腺癌(PC)转移中的关键影响仍旧大部分未知。最近,有研究人员为了鉴定转移性PCs中HOXB13的转录靶标,在人类前列腺肿瘤特异性AR结合位点附近进行了综合的差异化基因表达(DEGs)生物信息学分析。无监督主成分分析(PCA)表明HOXB13靶基因聚焦于

HOXB13是一个同源异型盒转录因子,并且与根治性前列腺切除术后复发有关。虽然HOXB13能够以环境依赖的方式来调控雄激素受体(AR)功能,它在前列腺癌(PC)转移中的关键影响仍旧大部分未知。

最近,有研究人员为了鉴定转移性PCs中HOXB13的转录靶标,在人类前列腺肿瘤特异性AR结合位点附近进行了综合的差异化基因表达(DEGs)生物信息学分析。无监督主成分分析(PCA)表明HOXB13靶基因聚焦于HOTPAM9。HOTPAM9包括了7个有丝分裂基因,并在PCs中过表达;另外,与原发性疾病相比,TRPM8和热激蛋白HSPB8的水平在转移性PCs中显著更低。CIT和HSPB8这2个基因集的整体平衡准确度为98.8%且阈值为0.2347,且能够充分的对转移进行分类。在多个转移性CRPC模型中,HSPB8 mRNA表达水平在HOXB13缺失后显著增加。微管抑制剂秋水仙碱处理或者外源方法使得HSPB8表达的增加能够抑制mCRPC细胞的迁移。

最后,研究人员指出,他们的结果表面了HOXB13能够促进PCs的转移,具体是通过有丝分裂激酶的调控和假定的肿瘤抑制基因的阻断两者协同来实现的。
