DNA Topoisomerases

31.1K
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 Replication

49.0K
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.

Summary

Circulating cell-free DNA activates the inflammasome, a key immune pathway. This activation is linked to recurrent stroke in patients with atherosclerosis.

Area of Science:

  • Immunology
  • Neurology
  • Cardiovascular Science

Background:

  • Atherosclerosis is a major risk factor for recurrent stroke.
  • Inflammasome activation plays a role in inflammatory diseases.
  • The role of circulating DNA in stroke pathogenesis is not fully understood.

Purpose of the Study:

  • To investigate the link between circulating DNA, inflammasome activation, and recurrent stroke in atherosclerosis patients.

Main Methods:

  • Assessed levels of circulating cell-free DNA (cfDNA) in patients.
  • Measured inflammasome activation markers.
  • Correlated cfDNA levels and inflammasome activity with stroke recurrence.

Main Results:

  • Elevated cfDNA levels were found in patients with recurrent stroke.

  • Higher inflammasome activation correlated with increased cfDNA.
  • cfDNA-driven inflammasome activation was associated with a higher risk of recurrent stroke.

    • Conclusions:

    • Circulating DNA is a potential driver of inflammasome activation.
    • This pathway contributes to recurrent stroke in atherosclerosis.
    • Targeting cfDNA or inflammasome could offer new therapeutic strategies.
