Abstract
: Considerable data indicate that oxidative stress and membrane lipid peroxidation contribute to neuronal degeneration in an array of age-related neurodegenerative disorders. In contrast, the impact of subtoxic levels of membrane lipid peroxidation on neuronal function is largely unknown. We now report that 4-hydroxy-nonenal (HNE), an aldehydic product of lipid peroxidation, disrupts coupling of muscarinic cholinergic receptors and metabotropic glutamate receptors to phospholipase C-linked GTP-binding proteins in cultured rat cerebrocortical neurons. At subtoxic concentrations, HNE markedly inhibited GTPase activity, inositol phosphate release, and elevation of intracellular calcium levels induced by carbachol (muscarinic agonist) and (RS)-3,5-dihydroxyphenyl glycine (metabotropic glutamate receptor agonist). Maximal impairment of agonist-induced responses occurred within 30 min of exposure to HNE. Other aldehydes, including malondialdehyde, had little effect on agonist-induced responses. Antioxidants that suppress lipid peroxidation did not prevent impairment of agonist-induced responses by HNE, whereas glutathione, which is known to bind and detoxify HNE, did prevent impairment of agonist-induced responses. HNE itself did not induce oxidative stress. Immunoprecipitation-western blot analysis using an antibody to HNE-protein conjugates showed that HNE can bind to Gαq/11. HNE also significantly suppressed inositol phosphate release induced by aluminum fluoride. Collectively, our data suggest that HNE plays a role in altering receptor-G protein coupling in neurons under conditions of oxidative stress that may occur both normally, and before cell degeneration and death in pathological settings.

Neurodegenerative diseases are hereditary or sporadic conditions that result in the progressive loss of the structure and function of neurons as well as neuronal death. Although a range of diseases lie under this umbrella term, Alzheimer’s disease (AD) and Parkinson’s disease (PD) are the most common neurodegenerative diseases that affect a large population around the globe. Alzheimer’s disease is characterized by the abnormal accumulation of extracellular amyloid-β plaques and intraneuronal neu...

Abstract 4-hydroxy-2-nonenal (HNE) is considered to be a strong marker of oxidative stress; the interaction between HNE and cellular proteins leads to the formation of HNE-protein adducts able to alter cellular homeostasis and cause the development of a pathological state. By virtue of its high lipid concentration, oxygen utilization, and the presence of metal ions participating to redox reactions, the brain is highly susceptible to the formation of free radicals and HNE-related compounds. A var...

Abstract Significance: Oxidative stress increases in the brain with aging and neurodegenerative diseases. Previous work emphasized irreversible oxidative damage in relation to cognitive impairment. This research has evolved to consider a continuum of alterations, from redox signaling to oxidative damage, which provides a basis for understanding the onset and progression of cognitive impairment. This review provides an update on research linking redox signaling to altered function of neural circu...

Abstract Thrombin and membrane lipid peroxidation (MLP) have been implicated in various central nervous system (CNS) disorders from CNS trauma to stroke, Alzheimer's (AD) and Parkinson's (PD) diseases. Because thrombin also induces MLP in platelets and its involvement in neurodegenerative diseases we hypothesized that its deleterious effects might, in part, involve formation of MLP in neuronal cells. We previously showed that thrombin induced caspase-3 mediated apoptosis in motor neurons, via a ...

Abstract Significance: Oxidative stress provokes the peroxidation of polyunsaturated fatty acids in cellular membranes, leading to the formation of aldheydes that, due to their high chemical reactivity, are considered to act as second messengers of oxidative stress. Among the aldehydes formed during lipid peroxidation (LPO), 4-hydroxy-2-nonenal (HNE) is produced at a high level and easily reacts with both low-molecular-weight compounds and macromolecules, such as proteins and DNA. In particular,...

Abstract Smoking has been suggested as one of the risk factor for amyotrophic lateral sclerosis (ALS) development. In order to investigate whether adverse effects of cigarette smoke in ALS have any association with increase in oxidative stress, disease severity, lipid hydroperoxides (LPO) and superoxide dismutase-1 (SOD1) levels were measured in biofluids of smoker and never smoker ALS patients and clinically correlated. Serum and CSF from sporadic ALS patients ( n = 50) diagnosed with El Escori...

Oxygen is essential for the growth and function of mammalian cells. However, alterations in oxygen homeostasis or abnormalities in the ability of a cell to respond to oxygen levels can result in OS defined as “an imbalance between oxidants and antioxidants in favor of the oxidants, potentially leading to damage” (Sies 1997). Within a given limit, production of oxidants is physiological since they are formed in normal aerobic metabolism, although they can be produced also at elevated rates under ...

In the present study we investigate the effect of Withania somnifera (WS) root extract and Withanolide A (WA) in restoring spatial memory deficit by inhibiting oxidative stress induced alteration in glutamergic neurotransmission. We demonstrate significant cellular loss in hippocampus of epileptic rats, visualized through decreased TOPRO stained neurons. Impaired spatial memory was observed in epileptic rats after Radial arm maze test. Treatment with WS and WA has resulted in increased number of...

Methanol extracts of 4 different colored (red, orange, yellow, and green) bell peppers (Capsicum annuum L.) were examined to (1) determine the total phenolic content (TPC), (2) compare the antioxidant activities, (3) assess the protective effects of extracts on H2O2-induced and 4-hydroxy-2-nonenal (HNE)-induced DNA damage using the Comet assay, and (4) examine the antiproliferative action of their extracts on HT-29 cells. Red and orange bell peppers had significantly higher levels of TPC than ye...
