It has been shown that cell volume regulation mechanisms play important roles in various cell functions. We demonstrated previously that volume-activated chloride channels were involved in cell volume regulation. The present study aimed to clarify the roles of various types of potassium channels in regulatory volume decrease (RVD) induced by hypotonic challenges in human nasopharyngeal carcinom...

BACKGROUND Although potassium channels are thought to be responsible for the initiation of hypoxic pulmonary vasoconstriction (HPV), their role in the HPV-inhibitory effect of volatile anesthetics is unclear. The current study tested if the HPV-inhibitory effect of isoflurane and sevoflurane can be affected by changing the potassium-channel opening status with specific potassium-channel inhibit...

Channelopathies are inherited genetic changes in ion channel genes that generate a disease. Given the pivotal role of voltage-dependent potassium channels in moderating neuronal excitability, it is not surprising that these channels are well represented among the channelopathies contributing to epilepsy. Voltage-dependent potassium channels are regarded as the “initial responders” that shape an...
