Evidence for specific binding of 15 hydroxyeicosatetraenoic acid to pituitary rat cells.

Abstract:

:Specific receptors for [3H]-15 HETE have been identified on GH3 cells, a cloned strain of rat pituitary cells. With incremental inputs of radioligand and a constant cell number, specific [3H]-15 HETE binding reached a plateau indicative of saturable binding sites. Ligand analysis of the Scatchard plot demonstrated a single class of high affinity binding sites with a dissociation constant (Kd) of 0.75 nM. 12 HETE competed with radiolabeled 15 HETE (IC50 = 1 x 10(-6) +/- 0.8 M). In contrast, arachidonic acid, leukotriene B4, prostaglandins E2 and F2 alpha did not compete with [3H]-15 HETE.
