Nucleosome Remodeling02:54

Nucleosome Remodeling

9.1K
Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure.
Nucleosome remodeling complex
Eukaryotic cells have specialized enzymes called ATP-dependent nucleosome remodeling enzymes. These enzymes...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Neurogenesis and Regeneration of Nervous Tissue

755
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Overview of DNA Repair02:25

Overview of DNA Repair

30.9K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

DNA Damage can Stall the Cell Cycle02:37

DNA Damage can Stall the Cell Cycle

9.1K
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...

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

461
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Genetics

Background:

  • Neurodegenerative diseases arise from complex genetic and environmental factors.
  • DNA damage and chromatin rearrangement are fundamental cellular processes implicated in neurodegeneration.
  • The interplay between DNA damage and chromatin organization in neurodegenerative diseases remains incompletely understood.

Purpose of the Study:

  • To review the current knowledge on the relationship between DNA damage and chromatin reorganization in neurodegenerative diseases.
  • To highlight the roles of hallmark neurodegenerative disease proteins in both DNA damage and chromatin dynamics.
  • To explore potential therapeutic strategies targeting common pathways.

Main Methods:

  • Literature review focusing on hallmark proteins in neurodegenerative diseases.
  • Analysis of studies linking DNA damage, chromatin organization, and disease mechanisms.
  • Synthesis of current understanding regarding protein functions in DNA repair and chromatin remodeling.

Main Results:

  • Hallmark proteins like tau, TDP-43, SOD1, FUS, HTT, α-synuclein, and APP are involved in both DNA damage response and chromatin regulation.
  • These proteins' dual roles suggest a direct link between DNA integrity, chromatin structure, and neurodegenerative pathology.
  • Evidence indicates that DNA damage and aberrant chromatin remodeling are integral to distinct neurodegenerative disease mechanisms.

Conclusions:

  • DNA damage and chromatin rearrangement are critical components of neurodegenerative disease pathogenesis.
  • Targeting shared modulators of DNA repair and chromatin reorganization presents a promising therapeutic avenue for neurodegenerative disorders.
  • Further research into these interconnected pathways could yield novel treatments for conditions like Alzheimer's, Parkinson's, and ALS.
