Abstract Objectives Chondrocyte ferroptosis contributes to osteoarthritis (OA) progression, and D‐mannose shows therapeutic value in many inflammatory conditions. Here, we investigated whether interferes chondrocyte ferroptotic cell death during osteoarthritic cartilage degeneration. Materials methods In vivo anterior cruciate ligament transection (ACLT)‐induced OA mouse model an vitro study of chondrocytes microenvironment induced by interleukin‐1β (IL‐1β) exposure were employed. Combined with Epas1 gene gain‐ loss‐of‐function, histology, immunofluorescence, quantitative RT‐PCR, Western blot, viability flow cytometry experiments performed evaluate the chondroprotective effects progression role hypoxia‐inducible factor 2 alpha (HIF‐2 α) D‐mannose‐induced resistance chondrocytes. Results exerted a effect attenuating sensitivity alleviated progression. HIF‐2α was identified as central mediator Furthermore, overexpression Ad‐ intra‐articular injection abolished eliminated suppressor. Conclusions alleviates suppressing HIF‐2α‐mediated ferroptosis, indicating be potential strategy for ferroptosis‐related diseases.

Iron homeostasis plays a positive role in articular cartilage health. Excessive iron or overload can induce oxidative stress damage chondrocytes and ferroptosis cell death, advancing knee osteoarthritis (KOA). However, up to date, few effective agents treat overload-induced KOA (IOKOA). Chinese herbal medicine (CHM) provides abundant resources for drug selection manage bone metabolic conditions, including osteoporosis. Biochanin A (BCA) is novel bioactive multifunctional natural compound isolated from Huangqi, which has protective effects on loss. Nevertheless, the function mechanism of BCA treating IOKOA are still elusive.This study seeks uncover potential therapeutic targets mechanisms management with accumulation.Iron dextrin (500 mg/kg) was intraperitoneally injected into mice establish overloaded model. OA induced through surgery, progression evaluated eight weeks following surgery. severity micro-CT Safranin-O/Fast green staining vivo. deposition joint synovium assessed using Perl's Prussian blue staining.

Fighting age-related orthopedic diseases: focusing on ferroptosis

Bone Research, Год журнала: 2023, Номер 11(1)

Опубликована: Март 1, 2023

Abstract Ferroptosis, a unique type of cell death, is characterized by iron-dependent accumulation and lipid peroxidation. It closely related to multiple biological processes, including iron metabolism, polyunsaturated fatty acid the biosynthesis compounds with antioxidant activities, glutathione. In past 10 years, increasing evidence has indicated potentially strong relationship between ferroptosis onset progression age-related orthopedic diseases, such as osteoporosis osteoarthritis. Therefore, in-depth knowledge regulatory mechanisms in diseases may help improve disease treatment prevention. This review provides an overview recent research on its influences bone cartilage homeostasis. begins brief systemic metabolism ferroptosis, particularly potential ferroptosis. presents discussion role promotion loss degradation inhibition osteogenesis. Finally, it focuses future targeting treat intention inspiring further clinical development therapeutic strategies.

Iron homeostasis and ferroptosis in human diseases: mechanisms and therapeutic prospects

Signal Transduction and Targeted Therapy, Год журнала: 2024, Номер 9(1)

Опубликована: Окт. 14, 2024

Iron, an essential mineral in the body, is involved numerous physiological processes, making maintenance of iron homeostasis crucial for overall health. Both overload and deficiency can cause various disorders human diseases. Ferroptosis, a form cell death dependent on iron, characterized by extensive peroxidation lipids. Unlike other kinds classical unprogrammed death, ferroptosis primarily linked to disruptions metabolism, lipid peroxidation, antioxidant system imbalance. Ferroptosis regulated through transcription, translation, post-translational modifications, which affect cellular sensitivity ferroptosis. Over past decade or so, diseases have been as part their etiology, including cancers, metabolic disorders, autoimmune diseases, central nervous cardiovascular musculoskeletal Ferroptosis-related proteins become attractive targets many major that are currently incurable, some regulators shown therapeutic effects clinical trials although further validation potential needed. Therefore, in-depth analysis its molecular mechanisms may offer additional strategies prevention treatment. In this review, we discuss significance contribution etiology development along with evidence supporting targeting approach. Importantly, evaluate recent promising interventions, providing guidance future targeted treatment therapies against

Abstract Osteoarthritis (OA) is a multifactorial and increasingly prevalent degenerative disease that affects the whole joint. The pathogenesis of OA poorly understood there lack therapeutic interventions to reverse pathological process this disease. Accumulating studies have shown overproduction reactive oxygen species (ROS) ROS-induced lipid peroxidation are involved in OA. 4-Hydroxy-2-nonenal (4-HNE) malondialdehyde (MDA) received considerable attention for their role cartilage degeneration subchondral bone remodeling during development. Ferroptosis form cell death characterized by control membrane recent suggested chondrocyte ferroptosis contributes progression. In review, we aim discuss peroxidation-derived 4-HNE MDA progression addition, potential controlling accumulation inhibiting discussed.

Abstract Ferroptosis is an iron‐dependent cell death that has been found to aggravate the progression of osteoarthritis (OA) and gut microbiota‐ OA axis refers bidirectional information network between microbiota OA, which may provide a new way protect OA. However, role microbiota‐derived metabolites in ferroptosis‐relative remains unclear. The objective this study was analyze protective effect its metabolite capsiate (CAT) on vivo vitro experiments. From June 2021 February 2022, 78 patients were evaluated retrospectively divided into two groups: health group ( n = 39) 40). Iron oxidative stress indicators determined peripheral blood samples. And then experiments, surgically destabilized medial meniscus (DMM) mice model established treated with CAT or Ferric Inhibitor‐1 (Fer‐1).
