虫草素通过Nrf2/HO-1通路抑制铁死亡延缓AKI向CKD转化的作用机制研究

2026-09-17 10:55:36   中国药房 2026年37卷第11期采用网络药理学和生物信息学分析并预测虫草素延缓AKI-CKD的信号通路及其与铁死亡途径的关系。采用细胞实验对预测结果进行验证:将人肾小管上皮细胞HK-2分为空白组、虫草素组、模型组、H2O2+虫草素组,除空白组和虫草素组外,其余各组加入150 μmol/L H2O2处理72 h以诱导细胞持续性氧化应激损伤;虫草素(40 μmol/L)干预72 h后,检测细胞中谷胱甘肽过氧化物酶4(GPX4)...

代谢广度决定虫生真菌"三重身份"——PNAS重磅(英文版)

2026-09-16 11:40:47   UMD News / PNAS | 2026-07-01马里兰大学St.Leger团队发现,绿僵菌(M. robertsii)代谢广度越广,杀虫越快、植物根系定殖越强,破解"杀虫vs共生"权衡之谜,发表于《PNAS》(2026.07.01)。...

虫子是被"顶"死的,不是被毒死的——中科院拆开了绿僵菌/白僵菌的液压钻头:甘油在附着胞里堆出巨大压力,把虫壳硬生生穿透

2026-09-16 11:19:57   探微者真菌三剑客到今天凑齐了——第16期木霉打真菌,第17期淡紫拟青霉打线虫,这期收官:昆虫病原真菌(绿僵菌 Metarhizium 和白僵菌 Beauveria)打虫子。它们用的是同一种武器——附着胞(appressorium),但产生的破坏力来自一个你意想不到的物理原理:甘油渗透压。Trends in Microbiology 2024年发了一篇来自中科院的综述,把绿僵菌和白僵菌并排拆开了感染昆虫...

基于均匀设计与数学模型的蝉拟青霉麦角甾醇过氧化物发酵营养条件优化(中文简译版)

2026-09-16 10:41:33   科学报告 | (2022) 12:5853本研究通过单因素实验、均匀设计和非线性回归分析,优化了蝉拟青霉(Paecilomyces cicadae)产麦角甾醇过氧化物(EP)的培养基组分。优化后EP产量达256 μg/L,较未优化前提高5倍。通过建立Monod模型、Andrews模型、Contois模型和Aibe模型,分析了发酵液黏度、底物及产物对菌体生长的影响。结果表明:Monod模型能较好预测菌体生长;黏度与底物对EP浓度的影响显著...
