An Extracellular Pore‑Targeting Peptide Defines a Designable Allosteric Site in TRPV2

Advanced Science, EarlyView.
Structure‐guided peptide engineering yields Depiv2, a highly potent and subtype‐selective TRPV2 inhibitor that binds to the extracellular pore and remodels it into a closed, non‐conductive state. Depiv2 suppresses pathological cardiac hypertrophy, establishing the TRPV2 outer pore as a designable interface for selective peptide modulation.

Magnetically Guided Macrophage Immunobots Coordinate Iron‐Metabolic Cascades and Immunogenic Ferroptosis for Tumor Immunotherapy

Advanced Science, EarlyView.
Magnetically guided macrophage immunobots integrate active tumor targeting with immunometabolic therapy. After systemic administration, magnetic actuation enhances immunobot retention and tumor penetration, while LPS‐functionalized FePt microrollers sustain M1‐like polarization through inflammatory and iron‐amplified oxidative signaling and trigger ...

SAV1 in Cooperation With FKBP52 Participates in Implantation

Advanced Science, EarlyView.
The MST‐SAV1 complex modulates FKBP52 phosphorylation to fine‐tune PR activity, ensuring timely uterine transition to receptivity under estrogen signaling for implantation. Stromal SAV1 scaffolds MST1/2‐mediated FKBP52 phosphorylation via noncanonical Hippo to promote PR activity.

Nuclear IDH3A Drives Transcriptional Programs in Melanoma via the YBX1–JUN/FOS Axis

Advanced Science, EarlyView.
Genomic amplification drives aberrant nuclear localization of IDH3A in melanoma. Independent of its canonical metabolic activity, nuclear IDH3A cooperates with YBX1 to activate the c‐JUN/c‐FOS transcriptional program, while NONO facilitates its nuclear localization.

The Function of the Glutathione/Glutathione Peroxidase System in the Oxidative Stress Resistance Systems of Microbial Cells

Chinese Journal of Biotechnology, 2007
The physiological roles of the glutathione(GSH)/glutathione peroxidase(GPx) system in protecting microbial cells against oxidative stress were reviewed. In eukaryotic model microbe Saccharomyces cerevisiae,this system is obligatory in maintaining the redox balance and defending the oxidative stress. However, the GSH/GPx system only conditionally exists

A semiautomated system for measurement of glutathione in the assay of glutathione peroxidase

Analytical Biochemistry, 1978
Abstract The most commonly used assay procedures for measurement of glutathione (GSH) peroxidase are unsuitable for kinetic studies; therefore, a semiautomated system that is based upon the 5,5′-dithio-bis-2-nitrobenzoic acid (DTNB) reaction with sulfhydryls was developed for the assay of relatively purified samples of the enzyme.

A novel interaction of diethyldithiocarbamate with the glutathione/glutathione peroxidase system

International Journal of Radiation Oncology*Biology*Physics, 1986
Diethyldithiocarbamate (DDC) exhibits a variety of pharmacologic activities, including both radioprotective and sensitizing properties. Since the glutathione/glutathione peroxidase system may be a significant factor in determining radiation sensitivity, the potential mechanisms of action of DDC in relation to this system were examined in vitro.

Glutathione-mediated detoxification systems in plants

Current Opinion in Plant Biology, 1998
Recent work has highlighted the presence of diverse glutathione-dependent enzymes in plants with potential roles in the detoxification of both xenobiotic and endogenous compounds. In particular, studies on glutathione transferases are further characterising their role in xenobiotic metabolism, and also raising intriguing possible roles in endogenous ...

The systemic availability of oral glutathione

European Journal of Clinical Pharmacology, 1992
When the plasma glutathione concentration is low, such as in patients with HIV infection, alcoholics, and patients with cirrhosis, increasing the availability of circulating glutathione by oral administration might be of therapeutic benefit. To assess the feasibility of supplementing oral glutathione we have determined the systemic availability of ...

The biochemistry of selenium and the glutathione system

Environmental Toxicology and Pharmacology, 2001
In the context of defense against pro-oxidants, selenium and the glutathione (GSH) system play key functions. Major roles of GSH include direct interception of pro-oxidants, as well as a reduction of other antioxidants from their oxidized forms. Furthermore, GSH has ancillary functions, such as metabolism, cell signaling, and protein interactions, that
