The ferroptosis of osteoblasts has been demonstrated to play a significant role in the development steroid-induced osteonecrosis femoral head (SONFH). Additionally, microRNAs (miRNAs) have identified as regulators SONFH progression. However, precise miRNAs regulation osteoblast remains unclear. This study explored exosomal miR-150-3p, derived from bone marrow mesenchymal stem cells (BMSCs), SONFH. Dexamethasone (DEX) was used treat induce ferroptosis. BMSCs exosomes with different levels miR-150-3p were introduced into co-culture cells. To verify targeting relationship between growth factor independence 1 (Gfi1) and promoter, well beta-transducin repeat containing E3 ubiquitin protein ligase (BTRC), respectively, chromatin immunoprecipitation (ChIP), RNA (RIP), dual luciferase assays employed. It found that BMSCs-Exos-miR-150-3p mitigated DEX-triggered osteoblasts. MiR-150-3p directly targeted BTRC, leading its downregulation BTRC/Nuclear erythroid 2-related 2 (Nrf2) pathway involved inhibition DEX-induced by BMSCs-Exos-miR-150-3p. Overexpression BTRC reversed inhibitory effect In rat model, alleviated through BTRC/Nrf2. addition, Gfi1 bonded promoter inhibited transcription. silencing elevated improves cell viability BMSCs. conclusion, our results suggest alleviates suppressing BTRC/Nrf2 may be potential target for treatment.

Abstract Type 1 diabetes mellitus (T1DM) is characterized by progressive β-cell death, leading to loss and insufficient insulin secretion. Mesenchymal stem cells (MSCs) transplantation currently one of the most promising methods for replacement therapy. However, recent studies have shown that ferroptosis not only key mechanisms but also reasons extensive cell death within a short period time after MSCs transplantation. Ferroptosis new type regulated (RCD) iron-dependent accumulation lipid peroxides. Due weak antioxidant capacity β-cells, they are susceptible cytotoxic stimuli such as oxidative stress (OS), therefore ferroptosis. Transplanted extremely perturbations in their microenvironment, especially OS, which can weaken induce through In pathophysiological process T1DM, large amount reactive oxygen species (ROS) produced, causing OS. Therefore, targeting may be way protect β-cells improve therapeutic effect This review reviews research related MSCs, summarizes developed strategies help inhibit study aims understand mechanism transplantation, emphasize importance protecting improving survival function transplanted provide direction therapy T1DM future.

Abstract The unprecedented pandemic of COVID-19 swept millions lives in a short period, yet its menace continues among survivors the form post-COVID syndrome. An exponentially growing number suffer from cognitive impairment, with compelling evidence trajectory accelerated aging and neurodegeneration. novel enigmatic nature this yet-to-unfold pathology demands extensive research seeking answers for both molecular underpinnings potential therapeutic targets. Ferroptosis, an iron-dependent cell death, is strongly proposed underlying mechanism post-COVID-19 neurodegeneration discourse. incites neuroinflammation, iron dysregulation, reactive oxygen species (ROS) accumulation, antioxidant system repression, renin-angiotensin (RAS) disruption, clock gene alteration. These events pave way ferroptosis, which shows signature COVID-19, premature aging, neurodegenerative disorders. In search treatment, melatonin shines as promising ferroptosis inhibitor repeatedly reported safety tolerability. According to various studies, has proven efficacy attenuating severity certain manifestations, validating reputation anti-viral compound. Melatonin well-documented anti-aging properties combating neurodegenerative-related pathologies. can block leading since it efficient anti-inflammatory, chelator, antioxidant, angiotensin II antagonist, regulator. Therefore, we propose culprit behind melatonin, well-fitting inhibitor, treatment.

Melatonin is widely observed in the female reproductive system and regulates trophoblast cell functions, but its effects on embryo implantation underlying mechanisms are not well understood. By constructing an vitro culture model, we found that melatonin enhances migration human mouse cells. It also significantly promoted HTR-8/SVneo proliferation, inhibited apoptosis, enhanced migration, mitigated oxidative damage. Further investigation revealed increased rate of spheroids by promotes epithelial-mesenchymal transition (EMT) via growth differentiation factor 15 (GDF15)–mothers against decapentaplegic homolog 2/3 (SMAD2/3) pathway. Additionally, levels glutathione peroxidase 4 (GPX4) (GSH) cells upregulating expression GDF15, inhibiting reactive oxygen species (ROS) accumulation, increasing mitochondrial membrane potential, thus suppressing apoptosis during stress. In conclusion, EMT GDF15-SMAD2/3 pathway partially induces GPX4 through GDF15 to enhance damage resistance These findings highlight melatonin's regulatory role suggest new avenues for exploring biological reproduction clinical applications.
