Prostate Cancer P D:雄激素轴靶向治疗的前列腺癌患者中,胃肠道微生物组成差异研究

2018-07-19 AlexYang MedSci原创

胃肠道(GI)微生物能够影响癌症疗法的代谢、药物代谢动力学和毒性。但是,癌症治疗对GI微生物组成的影响却了解甚少。最近,有研究人员提出雄激素轴靶向治疗(ATT),包括巴比卡鲁胺、苯扎溴铵和乙酸阿比妥钠也许与GI微生物组成差异相关。研究人员分析了30名健康男性志愿者和具有不同临床状态前列腺癌男性患者的粪便样本,具体是通过16S rDNA扩增子测序技术来分析,并利用PICRUSt对鉴定的类群进行功能性

胃肠道(GI)微生物能够影响癌症疗法的代谢、药物代谢动力学和毒性。但是,癌症治疗对GI微生物组成的影响却了解甚少。最近,有研究人员提出雄激素轴靶向治疗(ATT),包括巴比卡鲁胺、苯扎溴铵和乙酸阿比妥钠也许与GI微生物组成差异相关。

研究人员分析了30名健康男性志愿者和具有不同临床状态前列腺癌男性患者的粪便样本,具体是通过16S rDNA扩增子测序技术来分析,并利用PICRUSt对鉴定的类群进行功能性的分析。研究发现,在健康男性和前列腺癌患者的GI微生物群众,alpha多样性具有显著的差异。进一步的分析鉴定了ATT治疗的男性在GI微生物中具有明显的组成差异,包括了对PD-1免疫治疗产生抗性的有关类群的更大丰度,包括了Akkermansia muciniphila和Ruminococcaceae spp。在功能性分析中,研究人员在接受口服ATT治疗男性的粪便微生物中,发现了一个广泛存在的与类固醇生物合成和类固醇激素生物合成有关的细菌基因信号通路。

最后,研究人员指出,在接受口服ATT药物男性的GI微生物中,是存在可测量的差异的。他们还推断了前列腺癌患者口服激素药物能够改变GI微生物,从而影响对ATT治疗的临床响应,且还能潜在的调节未来治疗方法(免疫治疗)的抗肿瘤作用。

Jpn J Clin Oncol:临床T3前列腺癌患者根治性前列腺切除后生化复发预测因子研究

临床T3前列腺癌患者经历根治性前列腺癌切除术后,癌症控制的效果仍旧不清楚。最近,有研究人员回顾了那些经历了根治性前列腺切除的1409名患者,时间为2007年4月到2014年12月,同时也包括了210名Ct3前列腺癌患者。研究排除了9名经历新辅助激素治疗的患者和3名跟踪调查失败的患者。临床阶段由一名经验丰富的放射科医生通过术前磁共振成像来判断。研究人员利用Cox比例风险分析了生化复发的预测因子。研究

Urol Int:术前睾丸素水平与阳性手术切缘风险正相关关系研究

最近,有研究人员在前列腺癌(PCA)中评估了术前总睾丸素(TT)作为阳性手术切缘(PSM)预测因子的情况。研究时间段在2014年11月到2017年7月,在476名PCA且只经历根治性前列腺切除术(RP)的患者中测量了术前TT水平,并且包括了所有风险等级的患者。手术切缘包括阴性、焦点阳性(单个或者小于1ml)和多焦点阳性(多于1个)。研究人员还利用多项逻辑回归模型评估了TT和临床风险因与PSM风险(

IJIR:白藜芦醇治疗能够维持放射治疗后阴茎的勃起功能

前列腺癌(PC)的放射治疗(RT)能够通过氧化胁迫引起神经血管结构的损伤,从而引起阴茎勃起功能障碍(ED)。最近,有研究人员评估了一种抗氧化剂-白藜芦醇在RT术后对ED的治疗效果。研究包括了5个小组的50只小鼠,包括了对照组和长期的或短期的溶媒或者白藜芦醇治疗。研究人员还获取了阴茎海绵体组织来分析谷胱甘肽(GSH)、一氧化氮(NO)、环磷酸鸟苷(cGMP)、8-OHdG水平和超氧化物歧化酶(SOD

Curr Mol Med:在前列腺癌中,MYPT1表达的减少能够促进肿瘤血管生成和不良预后

之前的研究阐释了靶向肌球蛋白磷酸酶1亚基(MYPT1)可能是microRNA-30d的直接靶标,并且能够促进前列腺癌(PCa)肿瘤血管生成和肿瘤的生长。最近,有研究人员调查了MYTP1表达的临床意义和在PCa中的功能。在小鼠模型中,通过功能的获得和丧失试验,研究人员发现,MYPT1能够抑制上皮细胞毛细血管的生成和体内试验中肿瘤血管的生成,并且还伴随VEGF和CD31表达的下调。另外,与良性前列腺癌
