Functional Genomics of Sulfur Metabolism in Rice: Insights From Transgenic and MicroRNA‐Based Strategies

Plant Direct, Volume 10, Issue 7, July 2026.
ABSTRACT Sulfur (S) is an essential macronutrient that plays critical roles in plant growth, redox homeostasis, stress adaptation, and immunity. In rice (Oryza sativa), sulfur deficiency is becoming increasingly common due to modern agricultural practices, yet the molecular regulation of sulfur metabolism remains incompletely understood.

A Phase 1 dose-escalation study of disulfiram and copper gluconate in patients with advanced solid tumors involving the liver using S-glutathionylation as a biomarker

BMC Cancer, 2021
Background Disulfiram and metals inactivate key oncoproteins resulting in anti-neoplastic activity. The goal of this study was to determine the maximum tolerated dose of copper when administered with disulfiram in patients with advanced solid tumors and ...

Redox signals and oxidative stress in the control of mitochondrial protein import

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Mitochondrial protein import is essential for organelle biogenesis and cellular homeostasis. It operates in an environment that is intrinsically shaped by redox chemistry. Mitochondria are major sources of reactive oxygen species (ROS), which arise as by‐products of oxidative phosphorylation. Cells therefore maintain sophisticated ROS‐handling

Cellular redox imbalance and changes of protein S-glutathionylation patterns are associated with senescence induced by oncogenic H-ras.

PLoS ONE, 2012
H-Ras oncogene requires deregulation of additional oncogenes or inactivation of tumor suppressor proteins to increase cell proliferation rate and transform cells. In fact, the expression of the constitutively activated H-RasV12 induces cell growth arrest

Non‐triazine photosystem II inhibitors provide effective control of metabolic atrazine‐resistant Amaranthus tuberculatus

Pest Management Science, Volume 82, Issue 7, Page 6864-6876, July 2026.
Metabolism‐based atrazine‐resistant Amaranthus tuberculatus populations ACR and MCR exhibit little or no cross‐resistance to amicarbazone and metribuzin, suggesting that non‐halogenated Group 5 herbicides can be utilized to re‐establish effective control.

Protocols for the Detection of S-Glutathionylated and S-Nitrosylated Proteins In Situ [PDF]

, 2010
The oxidation of protein cysteine residues represents significant posttranslational modifications that impact a wide variety of signal transduction cascades and diverse biological processes. Oxidation of cysteines occurs through reactions with reactive oxygen as well as nitrogen species.

Pharmacological treatment with a GABA(A) receptor modulator and a selective serotonin reuptake inhibitor as a mitigation strategy against aircraft noise‐induced cardiovascular and neuronal damage

British Journal of Pharmacology, Volume 183, Issue 13, Page 3762-3779, July 2026.
Abstract Background and Purpose Noise pollution, particularly by aircraft, is a significant risk factor for cardiovascular disease. Aircraft noise activates stress response pathways in the brain, via the amygdala, the sympathetic nervous system and the hypothalamic–pituitary–adrenal axis.

Spontaneous Non‐Catalyzed Molecular Reactions and Interactions in the Human Body: Biomedical Implications

Advanced Science, Volume 13, Issue 36, 29 June 2026.
ABSTRACT The human body functions as a natural reactor for a vast network of chemical and biological reactions and physical interactions among small molecules, proteins, cells, and numerous other components. These reactions/interactions are essential for maintaining normal physiological functions.

S-Glutathionylation of metallothioneins by nitrosative/oxidative stress

Experimental Gerontology, 2008
Cystein residues within metallothionein (MT) structure have been shown to be particularly prone to S-nitrosylation. The objective of this study was to examine the possibility that MTs undergo S-glutathionylation under nitrosative/oxidative stress. MT from rabbit liver was treated with different concentrations of GSNO, diamide plus GSH or H(2)O(2) plus ...
