Myoglobin and troponin concentrations are increased in early stage deep tissue injury
Title: Myoglobin and troponin concentrations are increased in early stage deep tissue injury.
In rhabdomyolytic rats, the level of heme and free iron in cytoplasm and mitochondria of kidney cells is remarkably increased while inhibition of proteolysis results in further elevation of myoglobin content in the renal tissue.
Title: The role of myoglobin degradation in nephrotoxicity after rhabdomyolysis.
After reperfusion, there was no significant increase in dialysate myoglobin concentration. MDL-28170 did not affect dialysate myoglobin concentration during occlusion or after reperfusion.
Title: Contribution of calpain to myoglobin efflux from cardiomyocytes during ischaemia and after reperfusion in anaesthetized rats.
Amphetamine-induced serum myoglobin release is a potential biomarker and possibly a factor in AMPH-induced toxicity processes.
Title: Serum myoglobin, but not lipopolysaccharides, is predictive of AMPH-induced striatal neurotoxicity.
Data suggest that rhabdomyolysis-induced kidney damage involves direct interaction of myoglobin with mitochondria possibly resulting in iron ions release from myoglobin's heme, which promotes the peroxidation of mitochondrial membranes.
Title: Myoglobin causes oxidative stress, increase of NO production and dysfunction of kidney's mitochondria.
intermittent hypobaric hypoxia decreased myocardial citrate synthase activity and myoglobin and decreased myocardial lactate dehydrogenase activity
Title: Enzyme activity and myoglobin concentration in rat myocardium and skeletal muscles after passive intermittent simulated altitude exposure.
The nitrite reductase activity of deoxymyoglobin reduces nitrite approximately 36 times faster than deoxyhemoglobin because of its lower heme redox potential.
Title: Deoxymyoglobin is a nitrite reductase that generates nitric oxide and regulates mitochondrial respiration.
Moreover, the similar Q10 for the DMb of solution versus cell Mb suggests that any temperature-dependent alteration of the postulated cell matrix does not significantly affect protein mobility.
Title: Anisotropy and temperature dependence of myoglobin translational diffusion in myocardium: implication for oxygen transport and cellular architecture.
Mb-facilitated diffusion has a higher poise in skeletal muscle than in myocardium.

bradykinin-induced NO does not interact significantly with cellular Mb to produce an NMR-detectable quantity of metMb in the perfused rat myocardium

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
