Zinc is an important component of cellular antioxidant defenses and dysregulation of zinc homeostasis is a risk factor for coronary heart disease and ischemia/reperfusion injury. Intracellular homeostasis of metals, such as zinc, iron and calcium are

Induction of heme oxygenase 1 (HO-1) favors immune-escape in BRAFV600 melanoma cells treated with Vemurafenib/PLX4032 under standard cell culture conditions. However, the oxygen tension under standard culture conditions (~18 kPa O2) is significantly

Defining physiological normoxia for improved translation of cell physiology to animal models and humans

Autor: Giovanni E. Mann, Thomas P. Keeley

Publikováno v: Keeley, T P & Mann, G E 2019, ' Defining physiological normoxia for improved translation of cell physiology to animal models and humans ', Physiological Reviews, vol. 99, no. 1, pp. 161-234 . https://doi.org/10.1152/physrev.00041.2017

The extensive oxygen gradient between the air we breathe (Po2~21 kPa) and its ultimate distribution within mitochondria (as low as ~0.5–1 kPa) is testament to the efforts expended in limiting its inherent toxicity. It has long been recognized that
