Sci Rep:Survivin的亚细胞区室化与前列腺癌的恶化和预后相关

2020-03-05 AlexYang MedSci原创

Survivin的亚细胞区室化在前列腺癌的生物学和预后中的作用仍旧未知。因此,有研究人员通过使用定量免疫组化在不少于3000个前列腺癌患者中调查了Survivin的亚细胞定位情况,并对公共数据库中的250名前列腺癌患者和健康捐赠者的转录组数据进行分析。研究发现,Survivin(BIRC5)基因表达在原发前列腺癌和转移中增加,但在复发和非复发前列腺癌中没有差异。Survivin免疫组化(IHC)染

Survivin的亚细胞区室化在前列腺癌的生物学和预后中的作用仍旧未知。因此,有研究人员通过使用定量免疫组化在不少于3000个前列腺癌患者中调查了Survivin的亚细胞定位情况,并对公共数据库中的250名前列腺癌患者和健康捐赠者的转录组数据进行分析。

研究发现,Survivin(BIRC5)基因表达在原发前列腺癌和转移中增加,但在复发和非复发前列腺癌中没有差异。Survivin免疫组化(IHC)染色在900(40.0%)个前列腺癌案例中只局限存在于细胞核,并在1338个肿瘤(59.4%)中存在不同水平的细胞质阳性反应。0.5%的前列腺癌不表达Survivin。细胞核和细胞质Survivin染色强度存在强烈的相关性,并且与pT类型和格林森得分也存在强烈的相关性。细胞质Survivin染色而非细胞核Survivin染色与前列腺癌中高度肿瘤细胞增殖相关。强烈的细胞质Survivin染色而非细胞核染色在单变量分析中能够预测不良结果。多变量Cox分析表明了Survivin并不是一个独立的预后标记。

最后,研究人员指出,他们为Survivin表达在前列腺癌中,尤其是在转移疾病增加提供了证据,其表达的增加也导致了更高的侵袭性和更严重的肿瘤恶化。另外,亚细胞区室化是Survivin癌症生物学的重要一方面,即只有细胞质,而非细胞核中的Survivin积累与前列腺癌的侵袭和预后相关。
