1MicroRNA-185通过靶向调节DN-MT1/PTEN/Akt通路抑制肝细胞癌的生长显示文摘近来研究表明miRNAs与肝癌的发生密切相关,然而单个miRNAs的具体作用机制仍未完全阐明。作者对microR-NA-185(miR-185)在肝细胞癌生物学功能和分子机制方面做了一些研究。实验发现,与非肿瘤性的肝脏实质相比, miR-185在人肝细胞癌组织中的表达减少;qRT-PCR检测显示,与原代肝细胞相比, miR-185在人肝细胞癌细胞中的表达下降;在体外人肝细胞癌细胞中miR-185的过表达会抑制细胞的增殖和侵袭,并且阻止SCID小鼠体内肿瘤的生长。miR-185的过表达能够抑制肝细胞癌细胞中DNMT13′端非翻译区域荧光素酶的活性,当 miR-185结合位点发生突变时,就不存在该效应;miR-185的复制或过表达会减少肝细胞癌细胞中DNMT1蛋白的表达。这些结果表明DNMT1是miR-185在肝细胞癌细胞中的靶向作用蛋白。 DNMT1在miR-185诱导抑制肝细胞癌的增殖中所起的作用,可进一步通过DNMT1的过表达阻止miR-185诱导抑制肝细胞癌细胞的增殖和侵袭这一事实所证实。 miR-185的复制或过表达能够减少PTEN启动子DNA甲基化并且提高PTEN的表达,从而抑制Akt磷酸化;如果DNMT1过表达,这些效应刚好相反。以上结果表明:miR-185靶向作用于DNMT1,通过诱导PTEN和抑制Akt,从而抑制肝细胞癌细胞的增殖,活化或激活miR-185可能成为肝细胞癌新的治疗策略之一。Qadir X V Han C Lu D 魏建国 许春伟 2014临床与实验病理学杂志2014,30,12:12
2油炸食品与心血管病风险和全因死亡率的关系:观察性研究的荟萃分析显示文摘研究者进行了一项荟萃分析,包括剂量反应分析,以定量确定油炸食品摄入与普通成年人群心血管病风险和全因死亡率之间的关系。方法:研究者在PubMed、EMBASE和Web of Science上检索2020年4月11日之前的所有文章。应用随机效应模型估计总的相对危险度(relative risks,RR)和95%CI。结果:与最低油炸食品摄入量相比,最高摄入量者主要心血管事件的总RR(95%CI)=1.28(1.15~1.43),n=17,I^(2)=82.0%,其中前瞻性研究:1.24(1.12~1.38),n=13,I^(2)=75.7%.刘青(译) 练桂丽(审校) Qin P Zhang M Han M Liu D Luo X Xu L Zeng Y Chen Q Wang T Chen X Zhou Q Li Q Qie R Wu X Li Y Zhang Y Wu Y Hu D Hu F 2021中华高血压杂志2021,29,2:3
