Induction of Neuronal Apoptosis by Thiol Oxidation
Abstract: The membrane‐permeant oxidizing agent 2,2′‐dithiodipyridine (DTDP) can induce Zn2+ release from metalloproteins in cell‐free systems. Here, we report that brief exposure to DTDP triggers… Expand

p38 Activation Is Required Upstream of Potassium Current Enhancement and Caspase Cleavage in Thiol Oxidant-Induced Neuronal Apoptosis
Oxidant-induced neuronal apoptosis has been shown to involve potassium and zinc dysregulation, energetic dysfunction, activation of stress-related kinases, and caspase cleavage. The temporal ordering… Expand

Caspase 3 activation is essential for neuroprotection in preconditioning
Sublethal insults can induce tolerance to subsequent stressors in neurons. As cell death activators such as ROS generation and decreased ATP can initiate tolerance, we tested whether other cellular… Expand

Electrophilic Cyclopentenone Neuroprostanes Are Anti-inflammatory Mediators Formed from the Peroxidation of the ω-3 Polyunsaturated Fatty Acid Docosahexaenoic Acid*
The ω-3 polyunsaturated fatty acid docosahexaenoic acid (DHA) possesses potent anti-inflammatory properties and has shown therapeutic benefit in numerous inflammatory diseases. However, the molecular… Expand

In Vitro Neurotoxicity of Methylisothiazolinone, a Commonly Used Industrial and Household Biocide, Proceeds via a Zinc and Extracellular Signal-Regulated Kinase Mitogen-Activated Protein…
Neurodegenerative disorders in humans may be triggered or exacerbated by exposure to occupational or environmental agents. Here, we show that a brief exposure to methylisothiazolinone, a widely used… Expand

Guidelines on experimental methods to assess mitochondrial dysfunction in cellular models of neurodegenerative diseases
Neurodegenerative diseases are a spectrum of chronic, debilitating disorders characterised by the progressive degeneration and death of neurons. Mitochondrial dysfunction has been implicated in most… Expand

Manganese exposure is cytotoxic and alters dopaminergic and GABAergic neurons within the basal ganglia
Manganese is an essential nutrient, integral to proper metabolism of amino acids, proteins and lipids. Excessive environmental exposure to manganese can produce extrapyramidal symptoms similar to… Expand

The selective p38 inhibitor SB-239063 protects primary neurons from mild to moderate excitotoxic injury.
Inhibition of the p38 mitogen-activated protein kinase (MAP Kinase) pathway reduces acute ischemic injury in vivo, suggesting a direct role for this signaling pathway in a number of neurodegenerative… Expand

Essential Role of the Redox-Sensitive Kinase p66shc in Determining Energetic and Oxidative Status and Cell Fate in Neuronal Preconditioning
Ischemic preconditioning is a phenomenon in which low-level stressful stimuli upregulate endogenous defensive programs, resulting in subsequent resistance to otherwise lethal injuries. We previously… Expand

Neurotoxic lipid peroxidation species formed by ischemic stroke increase injury.
Stroke is the third leading cause of death in the United States, yet no neuroprotective agents for treatment are clinically available. There is a pressing need to understand the signaling molecules… Expand
