TASK-1 potassium channel is not critically involved in mediating hypoxic pulmonary vasoconstriction of murine intra-pulmonary arteries. [PDF]
The two-pore domain potassium channel KCNK3 (TASK-1) is expressed in rat and human pulmonary artery smooth muscle cells. There, it is associated with hypoxia-induced signalling, and its dysfunction is linked to pathogenesis of human pulmonary ...

Effect of High-Altitude Exposure on the Heart
High altitude brings a great physiological change in human beings, both during short-term exposure and in lifelong residents, especially in the cardiovascular system.

Enhanced hypoxic pulmonary vasoconstriction in hypertension. [PDF]
In this study, we tested the hypothesis that hypoxic pulmonary vasoconstriction may be enhanced in systemic hypertension. The hypothesis took origin from the following two considerations: alveolar hypoxia constricts the pulmonary vessels by enhancing the Ca2+ penetration across sarcolemma of the smooth muscle cells and systemic high blood pressure is ...

Hypoxia Upregulates Estrogen Receptor β in Pulmonary Artery Endothelial Cells in a HIF-1α-Dependent Manner [PDF]
17β-Estradiol (E2) attenuates hypoxia-induced pulmonary hypertension (HPH) through estrogen receptor (ER)-dependent effects, including inhibition of hypoxia-induced endothelial cell proliferation; however, the mechanisms responsible for this remain ...

Regulation of rat intrapulmonary arterial tone by arachidonic acid and prostaglandin E2 during hypoxia. [PDF]
Arachidonic acid (AA) and its metabolites, prostaglandins (PG) are known to be involved in regulation of vascular homeostasis including vascular tone and vessel wall tension, but their potential role in Hypoxic pulmonary vasoconstriction (HPV) remains ...

CFTR and sphingolipids mediate hypoxic pulmonary vasoconstriction. [PDF]
Significance Hypoxic pulmonary vasoconstriction (HPV) is a physiological mechanism that protects against systemic hypoxemia by redistributing blood flow from poorly to better ventilated areas of the lung, thereby minimizing ventilation-perfusion mismatch.

Searching the ideal inhaled vasodilator: From nitric oxide to prostacyclin [PDF]
Today, the technique to directly administer vasodilators via the airway to treat pulmonary hypertension and to improve pulmonary gas exchange is widely accepted among clinicians.

EETs promote hypoxic pulmonary vasoconstriction via constrictor prostanoids.
To test the hypothesis that epoxyeicosatrienoic acids (EETs) facilitate pulmonary responses to hypoxia, male wild-type (WT) and soluble-epoxide hydrolase knockout (sEH-KO) mice, and WT mice chronically fed a sEH inhibitor (t-TUCB; 1 mg·kg-1·day-1) were ...

Transient but not genetic loss of miR-451 attenuates the development of pulmonary arterial hypertension [PDF]
<b>Rationale:</b> MicroRNAs are small non-coding RNAs involved in the regulation of gene expression and have recently been implicated in the development of pulmonary arterial hypertension (PAH).

Acute oxygen sensing: diverse but convergent mechanisms in airway and arterial chemoreceptors [PDF]
Airway neuroepithelial bodies sense changes in inspired O2, whereas arterial O2 levels are monitored primarily by the carotid body. Both respond to hypoxia by initiating corrective cardiorespiratory reflexes, thereby optimising gas exchange in the face ...
