Systemic L-Buthionine -S-R-Sulfoximine Treatment Increases Plasma NGF and Upregulates L-cys/L-cys2 Transporter and γ-Glutamylcysteine Ligase mRNAs Through the NGF/TrkA/Akt/Nrf2 Pathway in the Striatum

open access: yesFrontiers in Cellular Neuroscience, 2019
Glutathione (GSH) is the most abundant intracellular antioxidant. GSH depletion leads to oxidative stress and neuronal damage in the central nervous system (CNS).

PKCδ sensitizes neuroblastoma cells to L-buthionine-sulfoximine and etoposide inducing reactive oxygen species overproduction and DNA damage. [PDF]

open access: yesPLoS ONE, 2011
Neuroblastoma is a type of pediatric cancer. The sensitivity of neuroblastoma (NB) cancer cells to chemotherapy and radiation is inhibited by the presence of antioxidants, such as glutathione (GSH), which is crucial in counteracting the endogenous ...

Reactive oxygen species, antioxidants and the regulation of plant development

open access: yesThe FEBS Journal, EarlyView.
The regulation of axillary bud outgrowth by the interplay between phytohormone and redox signals. Axillary bud outgrowth is regulated by cellular energy status and the balance between phytohormones, notably abscisic acid (ABA) and gibberellic acid (GA).

Thiolane Sulfoximines as Azide Surrogates for Quinolyl Nitrenes: Photochemical Access to Ortho‐Diaminoquinolines

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.
Thiolane sulfoximines provide practical and safer surrogates for hazardous azides in nitrene photochemistry, enabling direct access to 7,8‐diaminoquinolines and fused δ‐lactams. DFT calculations support the reaction mechanism and rationalize product selectivity.

A Cascaded DNA Nanocircuit for Multi‐Signal‐Responsive Precision siRNA Delivery in Cancer Therapy

open access: yesAdvanced Science, Volume 13, Issue 63, 12 November 2026.
A cascaded dual‐AND logic DNA nanocircuit is engineered to respond to three tumor‐specific signals in a sequential manner: extracellular acidic pH, membrane‐overexpressed nucleolin (NCL), and intracellular glutathione (GSH). This programmable system selectively releases siPARP1 in glioblastoma (GBM), effectively silencing PARP1 and reversing TMZ ...

Gastric Cancer: Epidemiology, Risk Factors, Pathogenesis, Clinical Features, Diagnosis, and Management

open access: yesMedComm, Volume 7, Issue 11, November 2026.
This comprehensive review summarizes gastric cancer epidemiology, multifactorial risk factors (like infectious, dietary, genetic), pathogenesis such as precancerous evolution, molecular alterations, and a focus on the bidirectional interactions between gastric cancer cells and macrophages in the tumor microenvironment.

Natural Product‐Induced Ferroptosis to Overcome Therapy Resistance in Aggressive Cancers

open access: yesChemMedChem, Volume 21, Issue 20, 28 October 2026.
Natural products trigger ferroptosis through iron overload, glutathione depletion, glutathione peroxidase 4 inhibition, and reactive oxygen species accumulation, selectively targeting aggressive, and drug‐resistant cancers. Polyphenols, alkaloids and terpenoids emerge as promising multi‐target agents to overcome therapy resistance and improve future ...

ReactELISA method for quantifying methylglyoxal levels in plasma and cell cultures

open access: yesRedox Biology, 2019
Methylglyoxal (MG) is a toxic glycolytic by-product associated with increased levels of inflammation and oxidative stress and has been linked to ageing-related diseases, such as diabetes and Alzheimer's disease.

Multidrug Resistance-Associated Protein 1 (MRP1) mediated vincristine resistance: effects of N-acetylcysteine and Buthionine Sulfoximine

open access: yesCancer Cell International, 2005
Background Multidrug resistance mediated by the multidrug resistance-associated protein 1 (MRP1) decreases cellular drug accumulation. The exact mechanism of MRP1 involved multidrug resistance has not been clarified yet, though glutathione (GSH) is ...
