Cancer Gene Ther:在前列腺癌细胞中,SOCS3过表达能够增加对NK细胞的敏感性

2019-01-10 AlexYang MedSci原创

前列腺癌是男性中最常见的癌症之一。IL-6/JAK/STAT3信号途径的过度激活和SOCS3的沉默在前列腺癌中经常出现。最近,有研究人员开发了Ad-SOCS3基因疗法来对前列腺癌进行治疗,并且调查了是否Ad-SOCS3能够增加对NK细胞的敏感性。研究人员指出,Ad-SOCS3能够显著的抑制去势难治性前列腺癌(CRPC)细胞系的生长,包括pSTAT3、DU-145 (在10, 20和40 MOI)、

前列腺癌是男性中最常见的癌症之一。IL-6/JAK/STAT3信号途径的过度激活和SOCS3的沉默在前列腺癌中经常出现。

最近,有研究人员开发了Ad-SOCS3基因疗法来对前列腺癌进行治疗,并且调查了是否Ad-SOCS3能够增加对NK细胞的敏感性。研究人员指出,Ad-SOCS3能够显著的抑制去势难治性前列腺癌(CRPC)细胞系的生长,包括pSTAT3、DU-145 (在10, 20和40 MOI)、 TRAMP-C2 (在40 MOI),但是不包括STAT3基因敲除的PC-3 CRPC细胞系。Ad-SOCS3(40MOI)能够抑制IL-6在DU-145细胞中的产生和抑制TRAMP-C2细胞中由IFN-γ诱导的PD-L1的表达,还能增加DU-145细胞和TRAMP-C2细胞对NK细胞的敏感性。在DU-145小鼠异种种植模型中,瘤内注射1×108 pfu Ad-SOCS3(1周2次,共3周)能够显著的抑制肿瘤的生长。另外,Ad-SOCS3治疗结合瘤内注射1×107人类NK细胞表现出了最大的肿瘤生长抑制效果。

最后,研究人员指出,这些结果表明了Ad-SOCS3基因治疗结合NK细胞免疫治疗是过表达pSTAT3晚期CRPC的有力治疗选择。
