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

33.6K
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:

  • Oncology
  • Surgical Oncology
  • Radiology

Background:

  • Retroperitoneal sarcomas rarely present with continuous growth into the scrotum through the inguinal canal.
  • This presentation can mimic scrotal hernia, complicating initial diagnosis and management.

Observation:

  • A case of a 57-year-old male with a groin swelling initially suspected as scrotal hernia is presented.
  • Intraoperative findings revealed a large retroperitoneal mass, necessitating advanced imaging (CT, MRI) for diagnosis.
  • A systematic literature review of ten similar cases was conducted.

Findings:

  • Histological analysis confirmed a well-differentiated liposarcoma with clear resection margins.
  • The patient achieved complete clinical remission 22 months post-surgery.

Implications:

  • Preoperative suspicion of retroperitoneal involvement is critical for surgical planning.
  • Unclear cases require extended preoperative diagnostic workup to ensure optimal patient management and prognosis.
  • This highlights the importance of considering rare differential diagnoses in groin swellings.
