Mismatch Repair

6.5K
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.

Overview of DNA Repair

33.7K
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 Repair

26.3K
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.

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Area of Science:

  • Neuroscience
  • Maternal-Fetal Medicine
  • Surgical Innovation

Background:

  • Spina bifida is a common birth defect causing chronic disability.
  • Early detection and prenatal intervention are crucial for improving outcomes.
  • Advances in fetal surgery offer new treatment possibilities.

Purpose of the Study:

  • To evaluate the efficacy and safety of minimally invasive prenatal surgery for spina bifida.
  • To compare fetoscopic techniques with open fetal surgery.
  • To minimize maternal risks and improve fetal neurosurgical outcomes.

Main Methods:

  • Review of prenatal surgical techniques for spina bifida, including open fetal surgery and fetoscopic approaches.
  • Comparison of maternal obstetric outcomes and fetal neurosurgical results.
  • Analysis of risks associated with different surgical methods.

Main Results:

  • Fetoscopic repair of spina bifida demonstrates superior maternal obstetric outcomes compared to open fetal surgery, avoiding future pregnancy risks.
  • Fetal neurosurgical outcomes, including improved hindbrain herniation and reduced hydrocephalus treatment, are comparable between fetoscopic and open prenatal surgery.
  • The open fetoscopic approach reduces risks of membrane rupture and preterm delivery compared to percutaneous methods.

Conclusions:

  • Minimally invasive strategies for prenatal spina bifida treatment require further refinement.
  • Optimizing these techniques can maximize benefits for the child and minimize maternal risks, including preterm birth.
