Nat Commun:前馈α粒子放射治疗能够根治雄激素受体依赖的前列腺癌

2018-04-30 AlexYang MedSci原创

人类激肽释放酶肽酶2(hk2)是一种前列腺特异性酶,它的表达受雄激素受体(AR)控制。AR是前列腺癌(PCa)的核心致瘤驱使因子,并且在癌症的DNA修复过程是是关键的调控因子。最近,有研究人员报道了一个创新的治疗策略,该策略利用了激素-DNA修复回路来促使分子特异性的α粒子在PCa中的注入。前列腺癌α粒子注入是通过分子特异性靶标位点和针对hK2的人源化单克隆抗体hu11B6的内化来引起的,并且进一

人类激肽释放酶肽酶2(hk2)是一种前列腺特异性酶,它的表达受雄激素受体(AR)控制。AR是前列腺癌(PCa)的核心致瘤驱使因子,并且在癌症的DNA修复过程是是关键的调控因子。

最近,有研究人员报道了一个创新的治疗策略,该策略利用了激素-DNA修复回路来促使分子特异性的α粒子在PCa中的注入。前列腺癌α粒子注入是通过分子特异性靶标位点和针对hK2的人源化单克隆抗体hu11B6的内化来引起的,并且进一步的可以通过固有的DNA修复机制促进hK2(KLK2)在体内的表达来促进上述作用。 Hu11B6标记的锕-225单独注射能够根除疾病,并且在动物模型中能够显著的延长生存。

另外,由α粒子注入引起的DNA损伤能够诱导AR和随后的KLK2的表达,产生一种特殊的前馈调节机制,该机制能够增加hu11B6的结合能力。在非灵长类动物模型中的成像数据支持了在男性中使用hu11B6的可能性。

Eur J Cancer:卡巴他赛在激发试验在重度治疗转移难治性前列腺癌患者中的疗效分析

之前的转移性去势难治性前列腺癌(mCRPC)治疗选择多烯紫杉醇(DOC)、卡巴他赛(CABA)和新激素治疗(NHT)。因此,治疗选择有限。DOC的再激发由于毒性的积累,使用也是受限的。最近,有研究人员调查了CABA再激发在mCRPC中治疗的活性和安全性。研究总共包括了562名患者,其中69名患者接受了CABA再激发(25 mg/m2 q3w, 58%; 20 mg/m2 q3w, 27.5%; 其

CLIN CANCER RES:STAT5A/B阻滞使前列腺癌对放疗敏感

BJU Int:去势难治性前列腺癌(CRPC)患者中,间断性多烯紫杉醇治疗与持续性多烯紫杉醇治疗比较

最近,有研究人员在转移性趋势难治性(mCRPC)患者中调查了间断性间断性多烯紫杉醇治疗与持续性多烯紫杉醇治疗的优劣。研究包括了187名化疗的mCRPC患者,这些患者分配到两个不同的小组中:间断性多烯紫杉醇和持续性多烯紫杉醇。在两个小组中,多烯紫杉醇使用量为每周35mg/m2或者每3周75mg/m2。初级结果为一年生存率,次级结果为总生存、无进展自由生存(PFS)、治疗失败中位时间(TTF)和毒性。

与正常前列腺比较,前列腺-2的六次跨膜上皮抗原(STEAP2)表达在前列腺癌中增加,表明了STEAP2也许能够促进前列腺癌的恶化。最近,有研究人员进行了旨在阐明STEAP2在前列腺致瘤过程中的功能作用情况和评估将其敲除后是否能够减少前列腺癌细胞侵入能力的研究。研究人员将STEAP2 siRNA转化进入PC3和LNCaP细胞系中,并且分析了增殖、迁移、入侵和基因表达情况。研究人员根据格林森得分情况,
