Oxidative stress in heart and brain by the cancer chemotherapeutic drug adriamycin (ADR), used for treating solid tumors, is well established. Long‐term treatment with ADR in breast cancer patients has led to symptoms of cardiomyopathy. Less well recognized, but increasingly well documented, is cognitive dysfunction. After chemotherapy, free radical‐mediated oxidative stress has been reported in both heart and brain. We recently showed a significant increase in protein oxidation and lipid…

Doxorubicin-induced elevated oxidative stress and neurochemical alterations in brain and cognitive decline: protection by MESNA and insights into mechanisms of chemotherapy-induced cognitive impairment (“chemobrain”)
TLDR
This study is the first to demonstrate the protective effects of MESNA on Dox-related protein oxidation, cognitive decline, phosphocholine (PCho) levels, and PC-PLC activity in brain and suggests novel potential therapeutic targets and strategies to mitigate CICI.

TLDR
Results provide strong evidence that TNF-α is strongly associated, if not responsible for CICI, with central nervous system toxicity including mitochondrial dysfunction, neuronal death, and cognitive impairment.

The Precursor to Glutathione (GSH), γ-Glutamylcysteine (GGC), Can Ameliorate Oxidative Damage and Neuroinflammation Induced by Aβ40 Oligomers in Human Astrocytes
TLDR
This study examined the potential beneficial effects of GGC against exogenous Aβ40 oligomers on biomarkers of apoptosis and cell death, oxidative stress, and neuroinflammation, in human astrocytes and identifies yet another potential therapeutic strategy to attenuate the cytotoxic effects of Aβ oligomers in AD.
Oxidative Stress and Neurodegenerative Disorders
TLDR
The source, balance maintenance and physiologic functions of ROS, oxidative stress and its toxic mechanisms underlying a number of neurodegenerative diseases, and the possible involvement of ROS in chemotherapy-induced toxicity to the CNS and PNS are summarized.

γ‐glutamylcysteine ethyl ester‐induced up‐regulation of glutathione protects neurons against Aβ(1–42)‐mediated oxidative stress and neurotoxicity: Implications for Alzheimer's disease
TLDR
It is suggested that GCEE up‐regulates cellular GSH levels which, in turn, protects neurons against protein oxidation, loss of mitochondrial function, and DNA fragmentation induced by Aβ(1–42).
Free radical mediated oxidative stress and toxic side effects in brain induced by the anti cancer drug adriamycin: Insight into chemobrain
TLDR
A significant increase in levels of protein oxidation and lipid peroxidation and increased expression of MRP1 in brain isolated from mice, 72 h post i.p injection of ADR is demonstrated.
Elevation of mitochondrial glutathione by γ‐glutamylcysteine ethyl ester protects mitochondria against peroxynitrite‐induced oxidative stress
TLDR
Results suggest that GCEE may be effective in increasing mitochondrial GSH and may be prove to have therapeutic relevance in neurodegenerative disorders associated with oxidative stress and mitochondrial dysfunction.
Elevation of brain glutathione by γ‐glutamylcysteine ethyl ester protects against peroxynitrite‐induced oxidative stress
TLDR
The experiments suggest that GCEE is effective in increasing brain GSH levels and may potentially play an important therapeutic role in attenuating oxidative stress in neurodegenerative diseases associated with oxidative stress such as Alzheimer disease.
Adriamycin‐mediated nitration of manganese superoxide dismutase in the central nervous system: insight into the mechanism of chemobrain
TLDR
It is demonstrated that treatment with ADR led to an increased circulating level of tumor necrosis factor‐alpha in wild‐type mice and in mice deficient in the inducible form of nitric oxide (iNOSKO), and it is suggested that NO is an important mediator, coupling the effect of ADR with cytokine production and subsequent activation of iNOS expression.
Elevation of oxidative free radicals in Alzheimer's disease models can be attenuated by Ginkgo biloba extract EGb 761.
TLDR
The hypothesis of the involvement of Abeta and ROS in association with AD is supported as both in vitro and in vivo models displaying endogenous Abeta production displaying maximum attenuation were employed.

TLDR
Proteomic identification of two proteins found to be oxidized significantly in neuronal cultures treated with Aβ(1–42) are reported and pretreatment of neuronal cultures with γ‐glutamylcysteine ethyl ester, a compound that supplies the limiting substrate for the synthesis of glutathione and results in the upregulation of glutATHione in neuronal Cultures, protects both proteins against A β(1-42)‐mediated protein oxidation.

TLDR
The data suggest that 4-hydroxy-2-trans-nonenal may be an important mediator of oxidative stress-induced impairment of this detoxifying system and may thereby play a role in promoting neuronal cell death in AD.
