To elucidate the mechanism of palytoxin (PTX)-induced Na+ influx, we examined the effect
of amiloride, an inhibitor of Na+ H+-antiporter, on PTX-induced Na+ influx into cultured …

The effect of palytoxin (PTX), a potent marine toxin, on catecholamine (CA) secretion from
cultured bovine adrenal chromaffin cells was examined. PTX at concentrations of over 10 …

The effect of palytoxin (PTX), a potent marine toxin, on catecholamine release from cultured
bovine adrenal chromaffin cells was examined. PTX at concentrations of over 10− 9 M …

Palytoxin (PTx) is a potent membrane-active agent produced by marine coelenterates that
acts to stimulate bone resorption in organ culture at nanomolar concentrations. We report …

Palytoxin (PTx) at nanomolar concentrations enhances the permeability of mammalian cell
membranes to both Na+ and Ca2+. In basal human osteoblast-like Saos-2 cells, PTx (8 nM) …

Palytoxin, isolated from the zoanthid Palytoha species, is one of the most potent marine
toxins. Palytoxin(1 nM-i zM) caused a release of [3H] norepinephrine from clonal rat …

Abstract E. Habermann, M. Hudel and M.-E. Dauzenroth. Palytoxin promotes potassium
outflow from erythrocytes, HeLa and bovine adrenomedullary cells through its interaction …

Palytoxin (PTX) is known to bind to Na, K-ATPase, to inhibit its activity, and to induce cation
conductance, but the mechanism of these effects is still poorly understood. In Xenopus …

Palytoxin (PTX) opens a pathway for ions to pass through Na, K-ATPase. We investigate
here whether PTX also acts on nongastric H, K-ATPases. The following combinations of …

We examined the nature of the palytoxin (PTX)-induced channel and its relevance to the Ca
2+ mobilizing effect of the toxin on smooth muscle cells isolated from rabbit portal vein using …
