Cell Death & Disease:前列腺癌中PAX5能够诱导IDH1-AS1上调来促进肿瘤的生长

2019-10-13 AlexYang MedSci原创

前列腺癌(PCa)是世界范围内影响男性健康的主要恶性肿瘤之一。长非编码RNAs(lncRNAs)是一类长的转录本,并且报道在恶性肿瘤中是必要的调控因子。IDH1反义RS1(IDH1-AS1)是一个lncRNA,并能与基因互作来调控瓦博格效应。然而,其在PCa致瘤中的作用和机制仍旧不清楚。最近,有研究人员探索了IDH1-AS1在PCa肿瘤生长中的作用。研究发现,IDH1-AS1的表达在PCa样本和细

前列腺癌(PCa)是世界范围内影响男性健康的主要恶性肿瘤之一。长非编码RNAs(lncRNAs)是一类长的转录本,并且报道在恶性肿瘤中是必要的调控因子。IDH1反义RS1(IDH1-AS1)是一个lncRNA,并能与基因互作来调控瓦博格效应。然而,其在PCa致瘤中的作用和机制仍旧不清楚。

最近,有研究人员探索了IDH1-AS1在PCa肿瘤生长中的作用。研究发现,IDH1-AS1的表达在PCa样本和细胞系中上调。机理试验分析阐释了IDH1-AS1上调的相关机制。结果表明,PAX5是IDH1-AS1的转录激活因子。功能丧失分析阐释了体内体外试验中,IDH1-AS1的沉默能够抑制细胞的增殖和诱导细胞凋亡。通过基因芯片和GO分析,研究人员确定了IDH1-AS1能够通过上调ATG5的表达影响PCa细胞自噬。机理调查进一步确定了IDH1-AS1能够通过增强ATG5的稳定性或者阻断miR-216b-5p来上调ATG5的表达从而后转录调控ATG5的表达。最后,互补试验阐释了IDH1-AS1在PCa中能够通过ATG5诱导的细胞自噬促进增殖和凋亡。

最后,研究人员指出,他们的研究阐释了IDH1-AS1的功能和调控机制,也为PCa提供了新的生物标记。

Sci Rep:精液中的miRNAs可以作为前列腺癌诊断的非侵入性生物标记

尽管对前列腺组织是特异性的,血清前列腺特异性抗原(PSA)筛选经常导致前列腺癌的过度诊断和许多不必要的良性疾病活检,因此需要进一步的改善。最近,有研究人员对PSA水平适度提高的男性的精液的miRNAs表达水平进行了分析,从而评估其作为非侵入性生物标记来对PCa进行诊断和预后的应用价值。研究人员发现,高通量分析表明了PCa患者中miRNA表达模式与健康个体(HCt)相比发生了改变。研究人员考虑了输精

Nat Med:全基因组种系与前列腺癌表观遗传背景相关

肿瘤的发生可以由种系、环境和随机因素诱发。但这些因素是怎样互作产生肿瘤的分子表型的仍旧未知。最近,有研究人员在589个局部前列腺肿瘤中量化了种系多样性对体细胞表观基因组的影响。研究发现,倾向性风险位点影响了肿瘤的表观基因组,揭示了癌症易感性的机制。研究人员总共见顶了1178个位点与肿瘤组织中甲基化的改变有关,而不是非恶性肿瘤组织。这些肿瘤甲基化数量性状位点能够影响染色质结构以及RNA和蛋白的丰度。

Sci Rep:病灶间的异质性挑战了分子分型在原发性前列腺癌中的临床使用

前列腺癌是高度异质性的疾病,并且在起始诊断时往往具有典型的多个不同的癌症病灶。前列腺癌的分子分型能够游离的辅助精准的诊断和治疗。在癌症基因组数据库(TCGA)中公开了一个很有前景的分型工具,并基于每个患者的癌症样本成功的对74%的原发性前列腺癌分型,共分成了7组。最近,有研究人员探索了该分型工具的临床使用情况,他们在一个多病灶的背景下对该分型工具进行了测试。研究人员共分析了来自于39名患者的85个

Nat Commun:PTEN-ARID4B-PI3K途径鉴定了PTEN缺陷前列腺癌对ARID4B的依赖性

在前列腺癌中,PTEN经常发生变异。PTEN的肿瘤抑制子功能归结于其脂肪磷酸化活性且能够拮抗PI3K的作用。最近,有研究人员报道了PTEN-ARID4B-PI3K途径,其中PTEN能够抑制ARID4B的表达,而ARID4B是PI3K亚单元基因PIK3CA和PIK3R2的转录激活因子,且亚单元基因PIK3CA和PIK3R2对PI3K/AKT途径的激活是非常关键的。ARID4B和组蛋白H1结合到PIK

Sci Rep:前列腺癌细胞中AR无差异抗雄激素抗性驱使因子分析

二代抗雄激素类药物抑制雄激素受体(AR)是转移去势抵抗性前列腺癌(mCRPC)的标准治疗方法,但是不可避免的会导致抗性的产生。自从高效AR信号抑制剂的使用,大于20%的mCRPC的患者发展为不依赖AR抗性机制疾病。最近,有研究人员开发了2个抗雄激素药物和不依赖AR活性的去势抵抗性前列腺癌细胞模型,尽管模型中AR表达强烈(AR无差异)。这些模型对所有当今的AR信号抑制剂存在抗性。研究发现,这2个细胞

Sci Rep:亚洲前列腺癌患者中周围血栓栓塞性血管疾病与雄激素阻断治疗相关性分析

最近,有研究人员在前列腺癌(PCa)患者中调查了血栓栓塞的血管疾病在雄激素阻断治疗(ADT)后的风险情况。研究包括了24464名在2000-2008年新诊断为PCa的患者,且是通过纵向医疗保险数据库获得数据。所有的的PCa患者分成了2组:ADT组和非ADT组。ADT治疗的患者再分成手术去势组,化学去势组和单独抗雄激素组。研究人员通过依赖时间变量的多重Cox比例风险回归评估了肺栓塞(PE)、外周动脉
