Radiotherapy (RT) is an important part of the treatment many tumors. causes oxidative damage in all cellular compartments, including lipid membrane, on a random basis. Toxic peroxidation accumulation has only lately been linked to regulated type cell death known as ferroptosis. Iron required for ferroptosis sensitization cells.This work aimed study and iron metabolism before after RT BC patients.Eighty participants were included divided into two main groups: group I: 40 patients treated with RT. Group II: healthy volunteers' age sex matched control group. Venous blood samples collected from (prior RT) controls.

Abstract Ferroptosis, a regulated form of cellular death characterized by the iron-mediated accumulation lipid peroxides, provides novel avenue for delving into intersection metabolism, oxidative stress, and disease pathology. We have witnessed mounting fascination with ferroptosis, attributed to its pivotal roles across diverse physiological pathological conditions including developmental processes, metabolic dynamics, oncogenic pathways, neurodegenerative cascades, traumatic tissue injuries. By unraveling intricate underpinnings molecular machinery, contributors, signaling conduits, regulatory networks governing researchers aim bridge gap between intricacies this unique mode multifaceted implications health disease. In light rapidly advancing landscape ferroptosis research, we present comprehensive review aiming at extensive in origins progress human diseases. This concludes careful analysis potential treatment approaches carefully designed either inhibit or promote ferroptosis. Additionally, succinctly summarized therapeutic targets compounds that hold promise targeting within various facet underscores burgeoning possibilities manipulating as strategy. summary, enriched insights both investigators practitioners, while fostering an elevated comprehension latent translational utilities. revealing basic processes investigating possibilities, crucial resource scientists medical aiding deep understanding effects situations.

Ferritinophagy, a process involving selective autophagy of ferritin facilitated by nuclear receptor coactivator 4 (NCOA4), entails the recognition NCOA4 and subsequent delivery to autophagosome. Within autophagosome, undergoes degradation, leading release iron in lysosome. It is worth noting that excessive levels can trigger cell death. Recent evidence has elucidated significant roles played ferritinophagy ferroptosis regulation initiation progression cancer. Given crucial role tumor biology, it may serve as potential target for future anti-tumor therapeutic interventions. In this study, we have provided distinctive features its distinctions from ferroptosis. Moreover, briefly examined fundamental regulatory mechanisms ferritinophagy, encompassing involvement specific NCOA4, Nrf2/HO-1 signaling other pathways. Subsequently, synthesized current understanding impact on cancer applications, with particular emphasis utilization chemotherapy, nanomaterials, immunotherapy pathway purposes.

Hemochromatosis represents clinically one of the most important genetic storage diseases liver caused by iron overload, which is to be differentiated from hepatic overload due excessive release erythrocytes in patients with hemolytic disorders. This disorder under recent mechanistic discussion regarding ferroptosis, reactive oxygen species (ROS), gut microbiome, and alcohol abuse as a risk factor, are all topics this review article. Triggered released intracellular free ferritin via autophagic process ferritinophagy, ferroptosis involved hemochromatosis specific form iron-dependent regulated cell death. develops course mitochondrial injury associated additional accumulation, followed production ROS lipid peroxidation.

Iron overload emerges as a serious complication in myelodysplastic syndromes (MDS), particularly associated with frequent transfusions during the course of disease. The discovery and description hepcidin's mechanisms action have contributed to deeper understanding iron metabolism. existing literature reports potential role hepcidin MDS, yet these data are fragmented presented an unstructured, somewhat chaotic manner. Hence, address data, we performed systematic review observational studies examining levels MDS. An extensive three bibliographic databases (Pubmed, Web Science, Scopus) enabled us identify 12 studies. These focused primarily on adult patients low-risk MDS who underwent chelation therapy. in-depth analysis manuscripts led four main conclusions: (1) although high serum most generally not found significant difference between healthy individuals; (2) specific type; (3) strongly genetic status patients; (4) high-risk is levels. While furnished comprehensive summary significance there still gaps that future research should address. This pertains capacity predicting adverse outcomes for evaluating efficacy therapy or need transfusion.
