肾细胞癌(renal cell carcinoma,RCC)是成人肾脏的原发性恶性肿瘤。泛素-蛋白酶体系统(ubiquitinproteasome system,UPS)对控制蛋白质水平和调节生理病理过程至关重要。去泛素化酶(deubiquitinases,DUBs)是UPS的关键成分,特别是从靶蛋白中去除泛素链,通过严格调节正常生理学中泛素化和去泛素化之间的平衡,对蛋白质稳态和质量控制显示出至关重要的作用。越来越多的研究表明,功能异常的DUBs与RCC的进展和转移有关。根据底物的不同,一些DUB可能会抑制RCC,而另一些则促进。本文综述了RCC相关DUB的最新研究进展,描述了其分类、功能作用,总结了DUB在RCC中的作用和作用机制,并讨论了靶向DUBs用于癌症治疗。

Hydralazine represses Fpn ubiquitination to rescue injured neurons via competitive binding to UBA52

Journal of Pharmaceutical Analysis 2024年第1期14卷 86-99页

A major impedance to neuronal regeneration after peripheral nerve injury (PNI) is the activation of various programmed cell death mechanisms in the dorsal root ganglion. Ferroptosis is a form of programmed cell death distinguished by imbalance in iron and thiol metabolism, leading to lethal lipid peroxidation. However, the molecular mechanisms of ferroptosis in the context of PNI and nerve regeneration remain unclear. Ferroportin (Fpn), the only known mammalian nonheme iron export protein, plays a pivotal part in inhibiting ferroptosis by maintaining intracellular iron homeostasis. Here, we explored in vitro and in vivo the involvement of Fpn in neuronal ferroptosis. We first delineated that reactive oxygen species at the injury site induces neuronal ferroptosis by increasing intracellular iron via accelerated UBA52-driven ubiquitination and degradation of Fpn, and stimulation of lipid peroxidation. Early administration of the potent arterial vasodilator, hydralazine (HYD), decreases the ubiquitination of Fpn after PNI by binding to UBA52, leading to suppression of neuronal cell death and significant acceleration of axon regeneration and motor function recovery. HYD targeting of ferroptosis is a promising strategy for clinical management of PNI.

Nonreciprocal Photon Blockade Based on Zeeman Splittings Induced by a Fictitious Magnetic Field

Quantum nonreciprocity, such as nonreciprocal photon blockade, has attracted a great deal of attention due to its unique applications in quantum information processing. Its implementation primarily relies on rotating nonlinear systems, based on the Sagnac effect. Here, we propose an all-optical approach to achieve nonreciprocal photon blockade in an on-chip microring resonator coupled to a V-type Rb atom, which arises from the Zeeman splittings of the atomic hyperfine sublevels induced by the fictitious magnetic field of a circularly polarized control laser. The system manifests single-photon blockade or multi-photon tunneling when driven from opposite directions. This nonreciprocity results from the directional detunings between the countercirculating probe fields and the V-type atom, which does not require the mechanical rotation and facilitates integration. Our work opens up a new route to achieve on-chip integrable quantum nonreciprocity, enabling applications in chiral quantum technologies.

suppressive effect of Armoracia rusticana and three main glucosinolates on heterocyclic amine generation in roasted fish patties and their potential mechanism analyzed by density functional theory

引用

Food Science and Human Wellness 2024年

作者： Zhuoming Huang Tiantian Huang Hang su Zihao Yang Jie luo Qingwu Shen Chaoyi Xue Wei Quan College of Food Science and Technology， Hunan Agricultural University State Key Laboratory of Food Science and Resources， Jiangnan University

This study investigated the suppressive effects of Armoracia rusticana (AR) and its three main glucosinolates on both free and bound heterocyclic amines (HAs)， along with their mechanisms of free radical quenching using density functional theory. Fish patties were supplemented with varying concentrations of AR (0.5%～1.5%) and glucosinolates (0.005%～0.015%)， showing a dose-dependent inhibition of HAs and concurrent elimination of free radicals and HAs intermediates. Glucobrassicin demonstrated the highest reactivity， which was verified by frontier orbit analysis and conceptual density functional parameters， consistent with experimental findings. Furthermore， the O-H bond connected to the sulfur atom of glucobrassicin possessed the smallest bond dissociation enthalpy (BDE) value， which indicated that this particular hydrogen atom is most susceptible to react with free radicals. Overall， AR and its glucosinolates， especially glucobrassicin， show promise as natural additives for improving food safety and quality.
