Ferroptosis is a novel form of programmed cell death that is iron-dependent and distinct from autophagy, apoptosis, and necroptosis. It is primarily characterised by a decrease in glutathione peroxidase 4 (GPX4) activity, or by the accumulation of lipid peroxidation and reactive oxygen species (ROS). Renal fibrosis is a common pathological change in the progression of various primary and secondary renal diseases to end-stage renal disease and poses a serious threat to human health with high morbidity and mortality. Multiple pathways contribute to the development of renal fibrosis, with ferroptosis playing a crucial role in renal fibrosis pathogenesis due to its involvement in the production of ROS. Ferroptosis is related to several signalling pathways, including System Xc-/GPX4, abnormal iron metabolism and lipid peroxidation. A number of studies have indicated that ferroptosis is closely involved in the process of renal fibrosis caused by various kidney diseases such as glomerulonephritis, renal ischaemia-reperfusion injury, diabetic nephropathy and renal calculus. Identifying the underlying molecular mechanisms that determine cell death would open up new insights to address a therapeutic strategy to renal fibrosis. The review aimed to browse and summarise the known mechanisms of ferroptosis that may be associated with biological reactions of renal fibrosis.
期刊介绍:
Journal of Drug Targeting publishes papers and reviews on all aspects of drug delivery and targeting for molecular and macromolecular drugs including the design and characterization of carrier systems (whether colloidal, protein or polymeric) for both vitro and/or in vivo applications of these drugs.
Papers are not restricted to drugs delivered by way of a carrier, but also include studies on molecular and macromolecular drugs that are designed to target specific cellular or extra-cellular molecules. As such the journal publishes results on the activity, delivery and targeting of therapeutic peptides/proteins and nucleic acids including genes/plasmid DNA, gene silencing nucleic acids (e.g. small interfering (si)RNA, antisense oligonucleotides, ribozymes, DNAzymes), as well as aptamers, mononucleotides and monoclonal antibodies and their conjugates. The diagnostic application of targeting technologies as well as targeted delivery of diagnostic and imaging agents also fall within the scope of the journal. In addition, papers are sought on self-regulating systems, systems responsive to their environment and to external stimuli and those that can produce programmed, pulsed and otherwise complex delivery patterns.
