Mitochondrial functionality and cellular iron homeostasis are closely intertwined. Mitochondria are biosynthetic hubs for essential iron cofactors such as iron-sulfur (Fe-S) clusters and heme. These cofactors, in turn, enable key mitochondrial pathways, such as energy and metabolite production. Mishandling of mitochondrial iron is associated with a spectrum of human pathologies ranging from rare genetic disorders to common conditions. Here, we review mitochondrial iron utilization and its intersection with disease.

Intervertebral disc degeneration (IVDD) is a major cause of low back pain, where oxidative stress and mitochondrial dysfunction are key contributors. Additionally, ferroptosis, an iron-dependent form of cell death, is identified as a critical mechanism in IVDD pathogenesis. Herein, the therapeutic potential of gallic acid (GA)-derived PGA-Cu nanoparticles, enhanced with functional octapeptide (Cys-Lys-His-Gly-d-Arg-d-Tyr-Lys-Phe, SS08) to build the mitochondria-targeted nanoparticles (PGA-Cu@SS08), and embedded within a hydrogel matrix to form a nanocomposite hydrogel, is explored.

Dysregulated iron metabolism-induced ferroptosis is considered a key pathological mechanism in the development of osteoporosis (OP). G protein-coupled receptor 30 (GPR30, also known as Gper1) is an estrogen-binding receptor that has shown therapeutic benefits in patients with certain degenerative diseases. Moreover, several studies have demonstrated the anti-ferroptotic effects of estrogen receptor activation.

Background: Vagus nerve stimulation (VNS) exhibits protective effects against remote organ injury following ischemia-reperfusion (I/R). However, its effects on acute myocardial injury induced by hepatic I/R in rats, and the underlying mechanisms, remain unclear.
Methods: Thirty male rats were randomly assigned to five groups: Sham, I/R, VNS, VNS + Erastin, and VNS + DMSO.

Melanocyte (MC) death represents the basic pathological change of vitiligo. Kaempferol (Kae) is one of the main active ingredients of Tribulus terrestris, which is a commonly used Chinese medicine in the treatment of vitiligo. However, it remains unclear whether Kae can improve MC death, and hence relevant mechanisms need to be further explored.

Iron-sulfur (FeS) protein biogenesis in eukaryotes is mediated by two different machineries - one in the mitochondria and another in the cytoplasm. Glutaredoxin 5 (Grx5) is a component of the mitochondrial iron-sulfur cluster (ISC) machinery. Here we define the roles of Grx5 in maintaining overall mitochondrial/cellular FeS protein biogenesis, utilizing mitochondria and cytoplasm isolated from Saccharomyces cerevisiae cells.
