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

26.5K
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.

Pulmonary Hypertension: Classification and Pathogenesis

671
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Asthma: Pathogenesis and Management

1.4K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Summary

Rheumatoid arthritis (RA) progression involves three immune balances, not one mechanism. Understanding these equilibria is key for preventing joint damage and improving RA treatment strategies.

Area of Science:

  • Immunology
  • Rheumatology
  • Pathophysiology

Background:

  • Clinical heterogeneity in rheumatoid arthritis (RA) suggests complex immunological underpinnings.
  • Current understanding may not fully explain disease progression or treatment outcomes.

Purpose of the Study:

  • To propose a tripartite model of RA progression based on functional immunological balances.
  • To reframe RA as a disease of evolving equilibria for improved therapeutic strategies.

Main Methods:

  • Review of key immunological mechanisms in RA.
  • Conceptual framework development based on three functional balances: autoantibody function, inflammation vs. regulation, and stromal persistence vs. repair.

Main Results:

  • RA progression is characterized by three sequential functional balances: autoantibody function, cytokine regulation, and tissue homeostasis.
  • This model explains why clinical remission doesn't always prevent joint damage and highlights the importance of autoantibody function and tissue context.

Conclusions:

  • Rheumatoid arthritis is a dynamic disease of evolving equilibria.
  • The tripartite model offers insights for RA prevention, precision stratification, and restoring immune-stromal homeostasis.
