Cancer Gene Ther:去势抵抗性前列腺癌细胞中的基因疗法研究

2019-02-14 AlexYang MedSci原创

前列腺癌是全球范围内男性的第二大癌症。晚期阶段的前列腺癌患者通常通过雄激素阻断疗法(ADT)来治疗。然而,随着疾病的恶化,常常会发展成为不可治愈的去势抵抗性前列腺癌(CRPC)。JC型多瘤病毒(JCPyV)是一种人类DNA病毒。它的类病毒颗粒(VLPs)展现出了与原生病毒相似的趋向性,并且具有将外源基因转化进靶细胞进行表达的能力。研究人员在前列腺细胞中检测到了JCPyV;因此,前列腺癌细胞可能对J

前列腺癌是全球范围内男性的第二大癌症。晚期阶段的前列腺癌患者通常通过雄激素阻断疗法(ADT)来治疗。然而,随着疾病的恶化,常常会发展成为不可治愈的去势抵抗性前列腺癌(CRPC)。JC型多瘤病毒(JCPyV)是一种人类DNA病毒。它的类病毒颗粒(VLPs)展现出了与原生病毒相似的趋向性,并且具有将外源基因转化进靶细胞进行表达的能力。

研究人员在前列腺细胞中检测到了JCPyV;因此,前列腺癌细胞可能对JCPyV感染敏感,并且JCPyV VLPs可能可以作为前列腺癌基因治疗的的一个载体。最近,有研究人员构建了一种质粒(pPSAtk),该质粒通过使用前列腺特异性抗原(PSA)启动子,可以使胸苷激酶自杀基因只在雄激素受体(AR)阳性前列腺癌细胞中表达。研究人员还利用JCPyV VLPs作为载体来携带pPSAtk (PSAtk-VLPs)来在前列腺癌细胞中确定转录靶向性。另外,研究人员还发现在体外,PSAtk-VLPs只能杀死阳性AR CRPC22Rv1细胞,并且能够抑制肿瘤结节在异种种植小鼠模型中的生长。

最后,研究人员指出,他们的结果阐释了PSAtk-VLPs未来能够作为治疗CRPC患者新的选择。
