We quantified and studied the impact of post transfusional iron overload alone in post allogeneic HSCT. Median number of RBCs was 18. Ferritin was 532 mg/L. Liver iron content (LIC) was 117 mmoles/gdw. Correlation RBCs and ferritin was (r=0.81); RBCs and LIC was (r=0.84). The high ferritin group differed from normal ferritin group in terms of RBCs transfused (p<10(-3)), ALT (p<0.009). But occurrence of liver dysfunction was not significant. Magnitude of iron overload correlates closely to the number of RBCs and is quantified by MRI. Impact on liver dysfunction is moderate in absence of co-morbidity.

Excessive iron deposition can lead to ferroptosis, a form of iron-dependent cell death detrimental to neuronal survival. Microglia have been identified as having a high capacity for iron deposition, yet it remains unclear whether microglia undergo ferroptosis while phagocytosing excessive amounts of iron after spinal cord injury (SCI). Here, we observed scattered iron around the epicenter of the injured spinal cord at 7 days post-injury (dpi) in mice, which then accumulated in the lesion core at 14 dpi.

Nanomedicine-driven ferroptosis has emerged as a promising tumor treatment strategy through delivering exogenous iron and aggravating the lethal accumulation of lipid peroxides (LPO). However, the compensatory mechanisms of ferroptosis defense systems in cancer cells compromise the therapeutic efficacy and lead to potential side effects. Herein, a highly effective ferroptotic nano-amplifier is designed to synergistically promote ferroptosis via increasing intracellular labile iron, exacerbating lipid peroxidation and overcoming the defense system.

Cadmium (Cd) is a heavy metal that is a major hazardous environmental contaminant, ubiquitously present in the environment. Cd exposure has been closely associated with an increased prevalence and severity of neurological and cardiovascular diseases (CVD). The blood-brain barrier (BBB) plays a crucial role in protecting the brain from external environmental factors.

Acute kidney injury (AKI) involves a series of syndromes characterized by a rapid increase in creatinine levels. Ferroptosis, as an iron-dependent mode of programmed cell death, reportedly participates in the pathogenesis of AKI. Methyltransferase-like 3 (METTL3)-mediated m6A modification has been recently associated with various kidney diseases; however, the mechanism of METTL3 crosstalk with the molecules involved in ferroptosis is not clearly understood.
