说明

一般描述

核黄素是一种可溶于水的必需维生素。牛奶和鸡蛋是它的主要来源。核黄素在所有组织中通常与酶结合。核黄素在血浆中定位时，与白蛋白和特异性免疫球蛋白结合。

应用

(-)-核黄素已用于实验小鼠腹腔注射给药，以研究其对大脑中动脉阻塞卒中的保护作用。它也可与克雷布斯液一起使用，以体外模拟类缺血状态。

生化/生理作用

核黄素是活性辅酶因子核黄素 5′ -单磷酸盐（也称为黄素单核苷酸或 FMN）和黄素腺嘌呤二核苷酸 (FAD)的前体。饮食中的核黄素缺乏会导致一种称为阿里波黄素沉积症的综合征，其症状包括唇炎、口角炎、舌炎、角膜炎和脂溢性皮炎。核黄素具有抗肿瘤发展和心血管疾病的保护作用。其缺乏常影响涉及氧化还原反应的代谢。核黄素对铁的吸收、胃肠道发育、神经发生、角膜血管化和角膜混浊都有重要作用。

LetB Structure Reveals a Tunnel for Lipid Transport across the Bacterial Envelope.

Georgia L Isom et al.

Cell, 181(3), 653-664 (2020-05-04)

Gram-negative bacteria are surrounded by an outer membrane composed of phospholipids and lipopolysaccharide, which acts as a barrier and contributes to antibiotic resistance. The systems that mediate phospholipid trafficking across the periplasm, such as MCE (Mammalian Cell Entry) transporters, have…

Pancreatic cancer has a poor prognosis after complete macroscopic resection combined with chemotherapy. Even after neoadjuvant chemotherapy, R0 resection is often not possible. Moreover, current imaging techniques cannot reliably distinguish viable cancer cells from scar tissue at the resectional margin….

PasT of Escherichia coli sustains antibiotic tolerance and aerobic respiration as a bacterial homolog of mitochondrial Coq10.

Cinzia Fino et al.

MicrobiologyOpen, 9(8), e1064-e1064 (2020-06-20)

Antibiotic-tolerant persisters are often implicated in treatment failure of chronic and relapsing bacterial infections, but the underlying molecular mechanisms have remained elusive. Controversies revolve around the relative contribution of specific genetic switches called toxin-antitoxin (TA) modules and global modulation of…
