Nat BME: 通过综合性磷酸化蛋白质组学分析来自各种来源的心肌纤维化中的信号扰动

2020-07-25 MedSci原创 MedSci原创

心血管疾病是一种全球流行病,每年导致全世界1770万人死亡,并且据预测,它仍然是发达国家死亡的主要原因之一

血管病理发生和发展的分子机制可能是多方面的,并且很大程度上未知,这使治疗方向复杂化。 需要鉴定临床样品和心脏病理学实验模型在疾病过程中受到干扰的信号级联和分子过程,从而以改善慢性心血管疾病的早期发现,监测和管理。肥厚型心肌病(HCM)是最常见的遗传性心脏病。心肌纤维化是HCM的标志,被认为是导致快速性心律失常和心力衰竭发展的主要因素。纤维化通常在其他心血管疾病(例如缺血性和非缺血性心肌病)之后自然发生,其特征是心脏成纤维细胞过度增殖,肌成纤维细胞活化和纤维状细胞外基质(ECM)蛋白沉积增加。了解和靶向患者中干扰的信号传导级联至关重要。 要寻找新的诊断和治疗方式来对临床样品进行高通量分析外,测试和验证还将需要一种简单且具有代表性的心脏纤维化模型,以及可重现的方法来记录和分析由于病理发作或化学干预而发生的分子变化。

方法:使用磷酸化蛋白质组学分析作为统一的信息框架,我们对纤维化心脏组织的Biowire模型与来自HCM患者的心脏标本以及已建立的心脏肥大的横向主动脉缩窄(TAC)小鼠模型进行了比较,并分析和表征了信号扰动和纤维化。将所有受疾病影响的样本类型与匹配的非病理对照组织进行比较。这种系统的分析导致整个样本队列中数千种蛋白质,磷蛋白和磷酸化位点的鉴定和相对定量。此外,对于每组分析的实验,深度定量数据的生成使统计分析成为可能,揭示了数十种特定生物过程和信号传导途径,提供了有关心脏纤维化机制的进展和维持的潜在临床可行信息。病理。

结果:本研究涉及OOC模型系统以及动物和人类组织的磷酸化蛋白质组学分析,并概述了与患有HCM的患者的肌瘤切除术样本相关的磷酸化级联失调,以及最常用的心脏小鼠模型的最全面的磷酸化蛋白质组学分析 。

Circulation:转录后调控在心肌纤维化中的重要作用

纤维化是多种心脏病的一种常见病理,是由常驻成纤维细胞的激活所驱动的。心脏成纤维细胞向肌成纤维细胞转化的整体转录后机制尚不明确。采用RNA测序和核糖体分析技术,监测人心肌成纤维细胞活化过程中RNA转录和翻译的全基因组变化。研究人员采用RNA结合蛋白为基础的分析来识别成纤维基因的翻译调控因子。在转化生长因子β1驱动的人心肌成纤维细胞向肌成纤维细胞转化过程中,研究人员生成了核苷酸解旋的翻译组数据,证实了

Circulation:内皮细胞Foxp1通过TGF-β1-内皮素-1通路调控病理性心室重

病理性心肌纤维化和心肌肥厚,是左心室重构的共同特征,常进展成心力衰竭(心衰)。内皮细胞上的叉头框转录因子P1 (Foxp1)在心脏发育过程中起着重要作用。但EC-Foxp1对病理性心室重构的作用基本尚未明确。现研究人员对EC-Foxp1在病理性心脏重构中的作用及其机制进行研究。通过建立EC特异性Foxp1功能丧失或恢复的小鼠模型以及血管紧张素II灌注或主动脉缩窄术处理的小鼠模型来研究心室重构的机制

Heart:心源性猝死患者心电图与心肌纤维化的关系

心肌纤维化与QRS波延长、深Q波、T波倒置和QRS波碎裂有关。这些结果为识别纤维性心肌病和SCD风险患者提供了潜在有用的无创早期指标。

Circulation:纤维母细胞的初级纤毛对心肌纤维化的重要作用

初级纤毛是一种独特的细胞结构,见于多种类型的细胞,从细胞表面延伸出来,在脊椎动物的发育过程中起着至关重要的作用,包括心脏的发育。虽然纤毛细胞在心脏发育过程中的作用已有研究,但纤毛细胞在成人心脏中的作用尚无报道。现已明确某些编码纤毛蛋白的基因突变所导致的多囊肾病患者,常会伴发多种心血管症状。现研究人员对纤毛细胞在成人心脏中的作用进行研究。对C57BL/6小鼠胚胎、新生鼠和成年鼠的心脏进行组织学分析来

AP&T:肝纤维化和炎症也会促进心肌纤维化的发生

纤维化和炎症促进肝硬化的发展。但是,尚不清楚这些过程是否也有助于肝硬化性心肌病(CCM)的发展。新型的核磁共振成像可以量化细胞外体积(ECV),从而可以估算肝脏和心脏中的纤维化重构。本项研究旨在探讨肝
