Site-Specific Oxidative Stress Induction

Oxidative Stress – Environmental Induction

Induction of Oxidative Stress in Kidney

Oxidative stress has a critical role in the pathophysiology of several kidney diseases, and many complications of these diseases are mediated by oxidative stress, oxidative stress-related mediators, and inflammation. Several systemic diseases such as hypertension, diabetes mellitus, and hypercholesterolemia; infection; antibiotics, chemotherapeutics, and radiocontrast agents; and environmental ...

Induction of Oxidative Stress by Glutathione Depletion

Several recent studies have shown that certain forms of genetic or acquired hypertension are associated with oxidative stress and that animals with those types of hypertension respond favorably to antioxidant therapy. We hypothesize that oxidative stress may cause hypertension via (among other mechanisms) enhanced oxidation and inactivation of nitric oxide (NO). To test this hypothesis, Sprague...

Induction of chromosomal instability by chronic oxidative stress.

Earlier studies using GM10115 cells analyzed the capability of different DNA-damaging agents to induce genomic instability and found that acute oxidative stress was relatively inefficient at eliciting a persistent destabilization of chromosomes. To determine whether this situation would change under chronic exposure conditions, the human-hamster hybrid line GM10115 was cultured under conditions...

Site-specific oxidative cleavage of DNA by metallosalen-DNA conjugates.

Ni-salen-DNA conjugates, prepared by template-directed synthesis, targeted oxidative adduct formation and strand scission at deoxyguanosine sites in complementary DNA strands of Watson-Crick duplexes.
