Mismatch Repair

6.7K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Overview of DNA Repair

33.9K
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.

Base Excision Repair01:54

Base Excision Repair

26.4K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanics

Background:

  • Meniscal root tears, a type of meniscal injury, involve radial tears or avulsions at the posterior horn attachment.
  • These injuries lead to increased tibio-femoral contact pressure and altered knee joint kinematics.
  • Previous research indicates successful biomechanical restoration with medial meniscus root repair.

Purpose of the Study:

  • To review the diagnosis, imaging, and arthroscopic surgical techniques for medial and lateral meniscus root injuries.
  • To outline indications for operative management, including specific criteria for medial and lateral tears.
  • To discuss surgical pearls, complications, rehabilitation, and outcomes for meniscus root repairs.

Main Methods:

  • Review of existing literature and institutional experience.
  • Description of diagnostic and imaging modalities.
  • Detailed explanation of arthroscopic surgical techniques for meniscus root repair.

Main Results:

  • Medial meniscus root repair has demonstrated success in restoring normal knee joint biomechanics in cadaver studies.
  • Specific indications for surgical intervention are outlined for both medial and lateral meniscus root tears.
  • The review details surgical techniques, potential complications, and rehabilitation protocols.

Conclusions:

  • Meniscal root tears cause significant knee pathology and biomechanical alterations.
  • Arthroscopic repair is an effective treatment for select meniscal root tears, restoring joint function.
  • Comprehensive understanding of diagnosis, technique, and rehabilitation is crucial for optimal patient outcomes.
