Summary
Oxidative stress in Parkinson's disease (PD) involves nitric oxide (NO) modifying proteins via S-nitrosylation, impairing neuroprotection. This study introduces methods to detect S-nitrosylated proteins, aiding PD research.
Area of Science:
- Neuroscience
- Biochemistry
- Cellular Biology
Background:
- Parkinson's disease (PD) involves dopaminergic neuron degeneration.
- Oxidative stress and nitric oxide (NO) signaling imbalance are implicated in PD pathogenesis.
- S-nitrosylation, an NO-mediated protein modification, regulates crucial cellular processes.
Purpose of the Study:
- To investigate the role of S-nitrosylation in Parkinson's disease.
- To understand how nitrosative stress affects neuroprotective proteins.
- To present methods for detecting S-nitrosylated proteins.
Main Methods:
- Investigated the impact of nitrosative stress on protein S-nitrosylation.
- Assessed the functional consequences of S-nitrosylation on neuroprotective proteins.
- Introduced two common methods for detecting S-nitrosylated proteins in biological samples.
Main Results:
- Increased nitrosative stress leads to S-nitrosylation of neuroprotective proteins.
- S-nitrosylation compromises the function of these critical proteins.
- This functional impairment contributes to the development of Parkinson's disease.
Conclusions:
- S-nitrosylation of neuroprotective proteins is a key factor in PD pathogenesis.
- Detecting S-nitrosylated proteins is crucial for understanding PD.
- The presented methods facilitate the study of NO signaling in PD.

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

01:15Parkinson's Disease: Overview
2.5K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

2.6K
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase,...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

5.9K
Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.

2.5K
Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...
