What is Behavior?00:54

What is Behavior?

10.2K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Phase II Reactions: Methylation Reactions

694
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 Topoisomerases

35.1K
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 Helicases

23.9K
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...

DNA Replication02:40

DNA Replication

58.8K
DNA replication involves the separation of the two strands of the double helix, with each strand serving as a template from which the new complementary strand is copied.  After replication, each double-stranded DNA includes one parental or “old” strand and one “new” strand. This is known as semiconservative replication. The resulting DNA molecules have the same sequence and are divided equally into the two daughter cells.

Area of Science:

  • Neuroscience
  • Epigenetics
  • Molecular Biology

Background:

  • DNA methylation is sensitive to environmental factors and crucial for brain function.
  • 5-hydroxymethylcytosine (5hmC) is highly enriched in the brain, suggesting a unique role.
  • Distinguishing 5mC and 5hmC reveals independent links to behavior.

Purpose of the Study:

  • To review the dynamic nature of DNA methylation in the brain.
  • To explore the role of 5hmC in brain epigenetic regulation.
  • To highlight the clinical relevance of DNA methylation changes in psychiatric disorders.

Main Methods:

  • Review of recent scientific literature.
  • Analysis of genome-wide studies on DNA methylation.
  • Comparison of 5mC and 5hmC levels in brain tissue.

Main Results:

  • DNA methylation (5mC and 5hmC) is highly dynamic in the brain.
  • Independent disruptions in 5mC and 5hmC levels correlate with various behaviors.
  • 5hmC plays a significant role in mediating epigenetic effects in the brain.

Conclusions:

  • Dynamic DNA methylation, including 5mC and 5hmC, is critical for brain function and behavior.
  • Perturbations in these epigenetic marks are implicated in psychiatric disorders.
  • Understanding these mechanisms holds potential for clinical relevance in treating brain disorders.
