The movement of ions across cell membranes is essential for a wide variety of fundamental physiological processes, including secretion, muscle contraction and neuronal excitation. Faced with the ...

Voltage-gated potassium channels form potassium-selective pores in cell membranes. They open or close in response to changes in the transmembrane potential and are essential for generating action ...

A SIZABLE literature demonstrating electrocardiographic abnormalities in various disorders of potassium metabolism has developed in the last ten years. The earlier observations suggested a correlation ...

Researchers have revealed how a channel that controls cellular potassium levels causes metabolic rewiring in breast cancer cells, promoting tumour growth. Researchers have revealed how a channel that ...

A new study examines the consequences of muscle activity with surprising results, indicating that the extracellular accumulation of potassium that occurs in working muscles is considerably higher than ...

The sodium retention demonstrated by the space determinations and by balance studies 29 probably accounts for the water retention (edema) and at least some of the hypoproteinemia observed in our cases ...

Many tumors contain lurking immune cells, including T cells that are equipped to attack the cancerous tissue. But the chemistry inside the tumor silences these T cells, allowing the cancer to persist ...
