Rotenone selectively occludes sensitivity to hypoxia in rat carotid body glomus cells
(Wiley-Blackwell Publishing Ltd., 2003)
Carotid body glomus cells release transmitters in response to hypoxia due to the increase of excitability resulting from inhibition of O2 -regulated K+ channels. However, the mechanisms involved in the detection of changes ...

Regulation of oxygen sensing by ion channels
(2004)
O2 sensing is of critical importance for cell survival and adaptation of living organisms to changing environments or physiological conditions. O2-sensitive ion channels are major effectors of the cellular responses to ...

Abnormal sympathoadrenal development and systemic hypotension in PHD3-/- mice
(2008)
Cell culture studies have implicated the oxygen-sensitive hypoxia-inducible factor (HIF) prolyl hydroxylase PHD3 in the regulation of neuronal apoptosis. To better understand this function in vivo, we have created PHD3_/_ ...

Collapse of conductance Is prevented by a Glutamate residue conserved in voltage-dependent K+ channels
(2000)
Voltage-dependent K 1 channel gating is influenced by the permeating ions. Extracellular K 1 determines the occupation of sites in the channels where the cation interferes with the motion of the gates. When external [K 1] ...

Acute oxygen sensing in heme oxygenase-2 null mice
(2006)
Hemeoxygenase-2 (HO-2) is an antioxidant enzyme that can modulate recombinant maxi-K+ channels and has been proposed to be the acute O2 sensor in the carotid body (CB). We have tested the physiological contribution of this ...

The Mitochondrial SDHD Gene Is Required for Early Embryogenesis, and Its Partial Deficiency Results in Persistent Carotid Body Glomus Cell Activation with Full Responsiveness to Hypoxia
(2004)
The SDHD gene encodes one of the two membrane-anchoring proteins of the succinate dehydrogenase (complex II) of the mitochondrial electron transport chain. This gene has recently been proposed to be involved in oxygen ...
