Structural luteolysis was found decades ago to be induced by PRL in the hypophysectomized rat, but the mechanisms of this process are unknown. To gain information on mechanisms of luteal involution, we developed an animal model that circumv…

An elevation of ATP levels in luteal cells markedly enhances their response to gonadotropin. In contrast, depletion of ATP in all cells leads to a series of interrelated events that produces irreversible cell injury. Since the corpus luteum…

To evaluate the role of transmembrane ion flux on the acute response of luteal cells to LH, the effects of two drugs, ouabain and monensin, and changes in ion composition of the medium were examined. Ouabain, an inhibitor of the Na+ extrusi…
