Summary
Huntington disease (HD) involves CAG repeat expansion, leading to neurodegeneration. Protein oxidation disrupts metabolic pathways, contributing to HD
Area of Science:
- Neuroscience
- Genetics
- Biochemistry
Background:
- Huntington disease (HD) is an inherited neurodegenerative disorder.
- CAG repeat expansion in the huntingtin gene is the primary cause.
- Oxidative stress and protein oxidation are implicated in HD progression.
Purpose of the Study:
- To review recent advances in understanding protein oxidation in HD pathophysiology.
- To identify specific target proteins affected by oxidation.
- To elucidate the role of protein oxidation in HD molecular damage.
Main Methods:
- Literature review of recent research on Huntington disease.
- Focus on identified target proteins and their oxidation.
- Analysis of the impact of protein oxidation on metabolic pathways.
Main Results:
- Protein oxidation inactivates/degrades key proteins, impairing metabolic pathways.
- Oxidation of ATP synthesis enzymes contributes to energy deficiency.
- Oxidation affects protein folding/degradation (heat shock proteins, Valosin-containing protein) and vitamin B6 metabolism.
Conclusions:
- Protein oxidation is a significant factor in Huntington disease pathophysiology.
- Impaired metabolic pathways, energy deficiency, and disrupted protein homeostasis are linked to protein oxidation.
- Oxidation exacerbates cellular damage, worsening oxidative stress in HD.

01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
01:24Parkinson Disease ll: Pathophysiology
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
01:20Radical Autoxidation
The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...
01:17Oxidation of Phenols to Quinones
In the presence of oxidizing agents, phenols are oxidized to quinones. Quinones can be easily reduced back to phenols using mild reducing agents. The electron-donating hydroxyl group enhances the reactivity of the aromatic ring, enabling oxidation of the ring even in the absence of an α hydrogen.
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox property is crucial in...

01:24Parkinson Disease l: Introduction
Parkinson’s disease is a chronic, progressive neurodegenerative disorder that primarily affects movement. It is characterized by motor symptoms such as resting tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. Patients may notice hand tremors at rest, stiffness during movement, or a shuffling gait. In addition to motor features, non-motor symptoms include sleep disturbances, mood and behavioral changes, constipation, and cognitive impairment, all of which...
01:22Lysosomal Hydrolases
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
