Redox homeostasis regulates key cellular signaling pathways in both physiology and pathology. The cell's antioxidant response provides a defense against oxidative stress and establishes a redox tone permissive for cell signaling. The molecular regulation of the well-known Keap1/Nrf2 system acts as sensor responding to changes in redox homeostasis and is poorly studied in the heart. Importantly,...
Exercise redox biochemistry is of considerable interest owing to its translational value in health and disease. However, unaddressed conceptual, methodological and technical issues complicate attempts to unravel how exercise alters redox homeostasis in health and disease. Conceptual issues relate to misunderstandings that arise when the chemical heterogeneity of redox biology is disregarded: wh...
The jasmonate family of phytohormones plays central roles in plant development and stress acclimation. However, the architecture of their signaling circuits remains largely unknown. Here we describe a jasmonate family binding protein, cyclophilin 20-3 (CYP20-3), which regulates stress-responsive cellular redox homeostasis. (+)-12-Oxo-phytodienoic acid (OPDA) binding promotes CYP20-3 to form a c...
Formaldehyde (HCHO) and protoporphyrin, are in connection with redox homeostasis. Data show the importance of HCHO in proliferative as well as in apoptotic processes. Free protoporphyrin can be detected near the Zn-protoporphyrin in cancer and it has pro- and antioxidant forms depending on concentrations. The aim was to determine the amount of HCHO and protoporphyrin concentrations of erythrocy...
The present study shows that DR1114 (Hsp20), a small heat shock protein of the radiationresistant bacterium Deinococcus radiodurans, enhances tolerance to hydrogen peroxide (H2O2) stress when expressed in Escherichia coli. A protein profile comparison showed that E. coli cells overexpressing D. radiodurans Hsp20 (EC-pHsp20) activated the redox state proteins, thus maintaining redox homeostasis....
AIMS The maintenance of heme homeostasis, mucosa cell renewal, and redox environment in the intestine is essential to permit digestion, absorption, cell proliferation, cell apoptosis, and immune response and to avoid the development of gut disorders. The feline leukemia virus, subgroup C, receptor 1a (FLVCR1a) is a heme exporter expressed in almost all cell types, including intestinal cells. Th...
Chronic sustained hypoxia (CH) induces structural and functional adaptations in respiratory muscles of animal models, however the underlying molecular mechanisms are unclear. This study explores the putative role of CH-induced redox remodeling in a translational mouse model, with a focus on the sternohyoid-a representative upper airway dilator muscle involved in the control of pharyngeal airway...
Redox regulatory system controls normal cellular functions. Controlled changes in redox couples potential serve as components for signal transduction, similarly to the phosphorylation cascade. Cellular redox biology requires both compartimentalisation and communication of redox systems: the thermodynamic disequilibrium of the major redox switches allows rapid and sensitive responses to perturba...
