Am J Resp Crit Care:长期电子烟暴露改变人支气管上皮细胞蛋白质组!

2018-03-01 xing.T MedSci原创

由此可见,长期接触电子烟对肺脏有显著的生物效应,这些效应可能部分由PG/VG所介导。这些变化可能不是无害的,可能对慢性肺病的发生发展有临床意义。需要进一步的研究以确定电子烟对肺脏的影响程度。

电子香烟气化丙二醇/甘油(PG / VG)、尼古丁和香料。然而,气化的电子烟液体对肺部健康的长期影响仍是未知的。近日,呼吸内科以及重症医学领域权威杂志Am J Resp Crit Care上发表了一篇研究文章,该研究旨在评估长期吸入电子烟对肺上皮的影响。

研究人员对健康的非吸烟者、吸烟者和电子香烟用户进行支气管镜检查,以获得支气管刷活检和灌洗样本进行蛋白质组学研究。研究人员进一步采用体外和小鼠暴露模型来支持佐证在人体实验中的发现。

经纤维支气管镜检查显示,电子烟使用者呼吸道出现松散、红斑。从活检标本中的上皮细胞显示吸烟者和电子烟使用者呼吸道中有300个蛋白表达存在差异,只有78个蛋白在两组中均有差异表达,113个蛋白只在电子烟使用者中改变。例如,CYP1B1、MUC5AC和MUC4水平在电子烟使用者中增加。在培养人类呼吸道上皮和小鼠体内鼻黏膜上皮细胞中雾化的PG/VG单独引起MUC5AC蛋白显著增加。研究人员还发现,电子烟液体可以迅速进入细胞,PG/VG可以降低膜流动性,使蛋白质扩散受损。

由此可见,长期接触电子烟对肺脏有显著的生物效应,这些效应可能部分由PG/VG所介导。这些变化可能不是无害的,可能对慢性肺病的发生发展有临床意义。需要进一步的研究以确定电子烟对肺脏的影响程度。

J Periodontol:电子烟液对人体口腔成纤维细胞超微结构、胶原蛋白生成和溶酶体室的影响

电子烟作为一种更便宜,更安全的无烟产品替代传统香烟和可能的戒烟工具,最近受到许多吸烟者的青睐。 尽管这些电子产品的安全性尚未完全知晓,但是有证据表明它们对口腔细胞具有细胞毒性。 在作者之前的研究中,在人类牙龈成纤维细胞(HGFs)中证实了电子烟会导致活性氧产生和Bax表达的增加,进而发生凋亡。 本文进一步研究了电子烟液(含/不含尼古丁)对同一实验模型的影响。

PNAS:电子烟也致癌,还是彻底戒了吧!

电子烟(E-cig)一直被推广为非致癌物和更安全的烟草替代品。然而,1月29日发表在《美国科学院院报》(PNAS)杂志上的最新研究表明,电子烟中的尼古丁会破坏DNA和抑制DNA修复,从而可能导致肺癌和膀胱癌以及心脏病。

Sci Rep:电子烟和非电子烟使用者尿液中膀胱癌致癌物质比较

电子烟(EC)的使用的流行度越来越高,并且可以作为传统抽烟的替代品,原因是人们认为电子烟是一种更为安全的选择。与使用者认为ECs代表没有风险的观念不同,研究人员的起始研究阐释了电子烟液体中复杂的物质组成。传统的抽烟已被人们认识是膀胱癌发展的风险因子,并且先前的研究报道提醒了人们电子烟液体或者蒸汽中也许包括了那些引起膀胱癌发展的复合物。研究人员从13名电子烟使用者和10名非电子烟使用者中搜集了尿液样
