Impaired function of Fanconi anemia type C-deficient macrophages.
FA is a genetic disorder characterized by BM failure, developmental defects, and cancer predisposition. Previous studies suggest that FA patients exhibit alterations in immunologic function. However, it is unclear whether the defects are immune cell-autonomous or secondary to leukopenia from evolving BM failure. Given the central role that macrophages have in the innate immune response, inflamm...
متن کاملFanconi anemia type C-deficient hematopoietic stem/progenitor cells exhibit aberrant cell cycle control.
The pathogenesis of bone marrow failure in Fanconi anemia is poorly understood. Suggested mechanisms include enhanced apoptosis secondary to DNA damage and altered inhibitory cytokine signaling. Recent data determined that disrupted cell cycle control of hematopoietic stem and/or progenitor cells disrupts normal hematopoiesis with increased hematopoietic stem cell cycling resulting in diminishe...
متن کاملFrequency of Hypothyroidism in Fanconi Anemia
Background: Fanconi anemia (FA) is a rare, autosomal recessive (AR) and multifactorial disorder. A high prevalence of FA observed in Iran is perhaps due to the high rate of consanguineous marriages. This study investigates the extent of short stature in patients with FA, the frequency of hypothyroidism in FA and the correlation between height and hypothyroidism. Methods: Eighteen patients with ...
متن کاملEnhanced TNF-alpha-induced apoptosis in Fanconi anemia type C-deficient cells is dependent on apoptosis signal-regulating kinase 1.
Fanconi anemia (FA) is a chromosomal instability disorder characterized by progressive bone marrow failure. Experimental evidence suggests that enhanced oxidant and myelosuppressive cytokine-mediated apoptosis of hematopoietic stem and progenitor cells contributes to the pathogenesis of marrow failure in FA. However, the molecular mechanisms responsible for the apoptotic phenotype in hematopoie...
متن کاملImpaired mitophagy in Fanconi anemia is dependent on mitochondrial fission
Fanconi anemia (FA) is a rare genetic disorder associated with bone-marrow failure, genome instability and cancer predisposition. Recently, we and others have demonstrated dysfunctional mitochondria with morphological alterations in FA cells accompanied by high reactive oxygen species (ROS) levels. Mitochondrial morphology is regulated by continuous fusion and fission events and the misbalance ...
