Myoglobin (Mb) plays an important role at rest and during exercise as a reservoir of oxygen
and has been suggested to regulate NO• bioavailability under hypoxic/acidic conditions …

Recent studies of myoglobin (Mb) knockout (myo−/−) mice have extended our
understanding of Mb's diverse functions and have demonstrated a complex array of …

Myoglobin (Mb) is a regulator of O2 bioavailability in type I muscle and heart, at least when
tissue O2 levels drop. Mb also plays a role in regulating cellular nitric oxide (NO) pools …

Oxygen (O2) transport from air to mitochondria depends on both the mechanisms of
convection and diffusion. In the final step of the O2 cascade, from the capillary to myocyte …

Myoglobin (Mb) is an important intracellular oxygen-binding hemoprotein found in the
cytoplasm of skeletal and cardiac muscle tissue playing a well-known role in O2 storage and …

Myoglobin may serve a variety of functions in muscular oxygen supply, such as O2 storage,
facilitated O2 diffusion, and myoglobin-mediated oxidative phosphorylation. We studied the …

THE ROLE OF MYOGLOBIN as an oxygen storage protein in the muscles of diving birds and
mammals is well-established (8). In contrast, the function of the lower myoglobin content in …

Myoglobin (Mb) is an oxygen-binding muscular hemeprotein regulated via Ca2+-signaling
pathways involving calcineurin (CN), with Mb increases attributed to hypoxia, exercise, and …

Myoglobin (Mb) is a large protein that reversibly binds oxygen in the muscle cell and is
thought to be critical for O2 supply to the mitochondria during exercise. The role of Mb in …

Myoglobin is an abundant hemoprotein that is expressed in cardiomyocytes and oxidative
skeletal myofibers of vertebrates. Elegant studies using physiological, biochemical and …
