Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

1.7K
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...

Dynamic Equilibrium02:20

Dynamic Equilibrium

62.7K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

Phase II Reactions: Methylation Reactions01:17

Phase II Reactions: Methylation Reactions

739
Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

DNA Topoisomerases02:02

DNA Topoisomerases

35.6K
Topoisomerases are enzymes that relax overwound DNA molecules during various cell processes, including DNA replication and transcription. These enzymes regulate positive and negative DNA supercoiling without changing the nucleotide sequence. DNA overwinding in a clockwise direction results in positively supercoiled DNA, whereas underwinding in a counterclockwise direction produces negatively supercoiled DNA.
Types and Mechanism of action
Topoisomerases are divided into two main types. ...

DNA Helicases00:55

DNA Helicases

24.1K
DNA unwinding helicase enzymes are a type of motor protein. Motor proteins can translocate along filaments or polymers using energy generated from ATP hydrolysis. Helicases are involved in all the important cellular processes where DNA unwinding is required, such as DNA replication, repair, recombination, and transcription. They are present in all living organisms, but vary in their structure, function, and mechanism of action. For example, in prokaryotes, DnaB helicase binds and translocates...

Area of Science:

  • Neuroscience
  • Epigenetics
  • Molecular Biology

Background:

  • Neurogenesis continues throughout adult life, not just during embryonic development.
  • Epigenetic mechanisms like DNA methylation are vital for neurogenesis.
  • Historically, DNA methylation was considered stable, but recent findings show its dynamic nature.

Purpose of the Study:

  • To review current knowledge on DNA methylation dynamics in neurogenesis.
  • To highlight the roles of various DNA methylation forms and their associated proteins.
  • To discuss the interplay between DNA methylation and histone modifications.

Main Methods:

  • Review of recent scientific literature on DNA methylation and neurogenesis.
  • Analysis of the roles of different DNA methylation forms (5mC, 5hmC, 5fC, 5caC).
  • Examination of 'writer' and 'reader' proteins involved in DNA methylation.
  • Investigation of interactions with histone modifications.

Main Results:

  • DNA methylation is a dynamic process essential for adult neurogenesis.
  • Specific methylation forms (5mC, 5hmC, 5fC, 5caC) and their regulators ('writers', 'readers') are involved.
  • DNA methylation dynamics interact with histone modifications to control gene expression in neurogenesis.

Conclusions:

  • DNA methylation dynamics are fundamental to ongoing neurogenesis in the adult brain.
  • Understanding these epigenetic mechanisms offers insights into brain development and function.
  • Further research into DNA methylation dynamics can inform therapeutic strategies for neurological disorders.
