Overview of DNA Repair

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. Chemically...

Base Excision Repair

2020
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...

Long-patch Base Excision Repair

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: Lesion type: Depending on the type of base damage, a specific DNA glycosylase - mono or bifunctional, is recruited to the damaged site. While the sequential action of a monofunctional glycosylase favors long patch repair...
FAQs
The lesser tuberosity is important because it is the normal bone attachment site identified for the subscapularis tendon. Repairing the tendon at this location reconnects the muscle-tendon unit with the humerus, allowing the restored structure to contribute again to internal rotation, shoulder strength, and joint stability. Preparing this attachment site is therefore central to the repair.
Restoring the subscapularis addresses several consequences of tendon injury at once. The repaired structure can support internal rotation, contribute to overall shoulder strength, and help stabilize the joint. These functional goals explain why successful treatment may reduce pain and limitations while improving the patient’s ability to use the shoulder in daily or clinical settings.
Arthroscopic and open techniques provide two surgical approaches for carrying out the repair. The overview does not establish that one approach is universally superior; instead, it identifies both as established ways to mobilize the damaged tendon, prepare its attachment site, and secure it with sutures or anchors. This distinction helps describe the procedure without equating approach with outcome.
The procedure may be considered for traumatic tears, degenerative lesions, or selected injuries occurring with broader rotator cuff damage. These categories represent different clinical contexts rather than a single cause of dysfunction. In each setting, the relevance of repair relates to restoring the damaged tendon’s contribution to shoulder strength, internal rotation, and joint stability.
The operative sequence includes mobilizing the damaged tendon, preparing the lesser tuberosity where the tendon normally attaches, and securing the tendon with sutures or anchors. Surgeons may perform these steps arthroscopically or through an open technique. Together, the sequence re-establishes the tendon-to-bone connection that supports the intended functional recovery.
Rehabilitation supports both tendon healing and recovery of shoulder movement after the repair. Surgery re-establishes the tendon’s attachment, but functional improvement also depends on restoring motion and the shoulder capabilities affected by the tear. Its role is therefore complementary to the operation, helping translate structural repair into improved strength, internal rotation, stability, and reduced limitation.
