Summary
This review explores DNA damage and repair in amyotrophic lateral sclerosis (ALS) pathogenesis, highlighting genetic factors and unconventional DNA entities. Understanding these mechanisms is crucial for developing new ALS therapies beyond symptom management.
Area of Science:
- Neuroscience
- Genetics
- Molecular Biology
Background:
- Amyotrophic lateral sclerosis (ALS) presents complex pathophysiology due to clinical heterogeneity and diverse molecular/genetic factors.
- While genetic mutations are identified, the role of genome-wide DNA damage and repair in ALS initiation and progression remains unclear.
Purpose of the Study:
- To summarize current knowledge on DNA alterations and repair strategies in ALS.
- To discuss the potential involvement of unconventional DNA entities in ALS.
Main Methods:
- Review of existing literature on DNA damage, repair mechanisms, and genetic factors in ALS.
- Focus on specific genes like SOD1, FUS, TDP-43, and C9ORF72.
Main Results:
- Identified novel genetic factors contributing to both familial and sporadic ALS.
- Highlighted the incomplete understanding of DNA damage and repair's role in ALS.
- Discussed potential roles of transposable elements and extrachromosomal circular DNA.
Conclusions:
- Further research into DNA damage and repair in ALS is essential for a comprehensive understanding of the disease.
- This knowledge may pave the way for novel therapeutic strategies beyond current symptomatic treatments for ALS.

DNA Damage Can Stall the Cell Cycle
3.2K
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

Plasticity
3.1K
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...

Plasticizers
378
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Plastic Behavior
585
A material's elastic behavior is characterized by the disappearance of stress once the load is removed, allowing the material to return to its original state. However, when stress surpasses the yield point, yielding commences, marking the onset of plastic deformation or permanent set. This change from elastic to plastic behavior is influenced by the peak stress value and the duration before the load is removed. An intriguing observation occurs when a specimen is loaded, unloaded, and...

Plastic Deformations
477
It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms of maximum strain. Notably, the neutral axis, which coincides with the centroid during elastic bending, shifts away from the centroid under plastic...
