Background:

  • Genomic instability is a hallmark of cancer cells.
  • DNA rearrangements and replication dysfunction are linked to human diseases.
  • Submicroscopic rearrangements can cause gene dosage imbalances or disruption.

Purpose of the Study:

  • To develop sensitive, high-resolution techniques for analyzing DNA rearrangements.
  • To improve understanding of genome instability mechanisms.
  • To elucidate the role of chromosomal rearrangements in disease.

Main Methods:

  • Utilizing molecular combing technology.
  • Straightening and aligning genomic DNA molecules.
  • Performing single DNA molecule analysis.
