Lack of mitochondrial ferritin aggravated neurological deficits via enhancing oxidative stress in a traumatic brain injury murine model.
Age-related increase is found in FtMt and hypoxia-inducible factor-1a (HIF-1a) in murine retinal pigment epithelium (RPE).HIF-1alpha stabilization reduced the protein level of the mature, functional form of mitochondrial ferritin.
overexpression of MtFt causes a dramatic change in intracellular iron homeostasis and shunting iron to MtFt likely limits its availability for active iron proteins
ferritin H not only responds to changes in tissue iron (its classic role), but can actively regulate overall tissue iron balance
mitochondrial ferritin has a role in tumor growth inhibition by cytosolic iron deprivation
PIAS3 is a new regulator of ATF1 that regulates the ARE-mediated transcription of the ferritin H gene
Its association with cell types characterized by high metabolic activity and oxygen consumption suggests a role in protecting mitochondria from iron-dependent oxidative damage.
ionomycin-mediated induction of ferritin H may occur in an NFAT-independent manner but through post-transcriptional stabilization of the ferritin H mRNA.
ferritin H transcription is activated by rotenone via an oxidative stress-mediated pathway leading to antioxidant-responsive element activation
Our results provide evidence that the iron storage function of ferritin plays a major role in preventing iron-mediated cell and tissue damage.
These results suggest that the elevation of expression levels of FTMT in the reticulocytes of patients with alpha-thalassaemia may be associated with iron loading and oxidative stress.
Via activation of cAMP/PKA/CREB pathway and upregulation of the downstream FtMt expression.
The expression of FTMT appears regulated by a complex mechanism involving epigenetic events and interplay between transcription factors.
Study characterized a new human FtMt antibody, and with it created the first map of FtMt immunoreactivity in a monkey brainstem. This showed the widespread distribution of FtMt in various brainstem regions and co-localization with catecholaminergic neurons.
experimental overexpression of FTMT may modify mitochondrial iron availability and lead to ineffective erythropoiesis
FtMt mutation may determine a condition similar to haploinsufficiency resulting in a reduced protection from iron-dependent oxidative stress in mitochondria
Stat5-dependent transcriptional regulation is displaced by strong cytosolic iron starvation status induced by mitochondrial ferritin.
higher protein levels in prostate cancer cells expressing a dominant negative mutant of p66Shc
MtF is involved in the pathology of Alzheimer's disease and may play a neuroprotective role against oxidative stress
MtF expression is downregulated during ATRA-induced K562 cell differentiation, with concomitant downregulation of TfR1 and upregulation of Fn.
The analysis suggests that sequence variations in the coding region of FtMt are not involved in the development of myelodysplastic syndromes and Parkinson's disease.
Primary spontaneous pneumothorax in smokers is associated with lung macrophage oxidative stress. The response to this condition involves HIF-1alpha-mediated induction of HO-1, BVR and H-ferritin.
Human mitochondrial ferritin expressed in HeLa cells incorporates iron and affects cellular iron metabolism
RT-PCR studies showed MtF mRNA in circulating reticulocytes of 2 X-linked sideroblastic anemia patients but not controls. Most of the iron in perinuclear mitochondria of ring sideroblasts is in the form of MtF, a specific marker of sideroblastic anemia.
In contrast to previously published literature, this study demonstrates that the putative nucleation site does not play an important role in iron uptake or mineralization in H-chain ferritin.
Data reveal striking differences in iron oxidation and hydrolysis chemistry between human mitochondrial ferritin and human H-chain ferritin despite their similar diiron ferroxidase centers.
These results suggest that hemin activates the transcription of the ferritin H gene during K562 erythroid differentiation by Ref-1-mediated activation of these b-zip transcription factors to the Antioxidant-responsive Elements.
functional analysis of an H ferritin promoter allele carrying a G to T substitution adjacent to the Bbf binding site, in position -69
Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Has ferroxidase activity. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation (By similarity).
