The Friedreich's ataxia protein frataxin modulates DNA base excision repair in prokaryotes and mammals
DNA-repair mechanisms enable cells to maintain their genetic information by protecting it from mutations that may cause malignant growth. Recent evidence suggests that specific DNA-repair enzymes contain ISCs (iron-sulfur clusters). The nuclearencoded protein frataxin is essential for the mitochondrial biosynthesis of ISCs. Frataxin deficiency causes a neurodegenerative disorder named Friedreic...
متن کاملLow Serum 25‑hydroxyvitamin D levels: Predictive Value of Hematological and Inflammatory Markers in Patients with Urinary Tract Infection
Background: Low vitamin D has been linked to enhance inflammatory markers in various pathological conditions. We aimed to evaluate the urinary tract infection (UTI)-associated hematological and inflammatory markers mediated by low serum levels of 25-hydroxyvitamin D [25(OH)D]. Methods: Vitamin D level, hematological indices (Neutrophil-to-lymphocyte ratio [NLR], Monocyte-to-lymphocyte ratio [M...
متن کاملThe Impact of Base Excision DNA Repair in Age-Related Neurodegenerative Diseases
The aging process and several age-related neurodegenerative disorders have been linked to elevated levels of DNA damage induced by ROS and deficiency in DNA repair mechanisms. DNA damage induced by ROS is a byproduct of cellular respiration and accumulation of damage over time, is a fundamental aspect of a main theory of aging. Mitochondria have a pivotal role in generating cellular oxidative s...
متن کاملAn adult patient with Nijmegen Breakage Syndrome and Hodgkin's Lymphoma
BACKGROUND Nijmegen Breakage Syndrome (NBS) is a rare autosomal recessive DNA repair disorder characterized by immune deficiency, microcephaly, mental retardation and a disposition for the development of hematological malignancies. So far, mostly pediatric patients have been described, since the underlying condition is often fatal before adulthood. Many patients diagnosed with Hodgkin lymphoma ...
متن کاملHigh Incidence of HPV-Associated Head and Neck Cancers in FA Deficient Mice Is Associated with E7’s Induction of DNA Damage through Its Inactivation of Pocket Proteins
Fanconi anemia (FA) patients are highly susceptible to solid tumors at multiple anatomical sites including head and neck region. A subset of head and neck cancers (HNCs) is associated with 'high-risk' HPVs, particularly HPV16. However, the correlation between HPV oncogenes and cancers in FA patients is still unclear. We previously learned that FA deficiency in mice predisposes HPV16 E7 transgen...
