Abstract:
Previous experiments examined interactions among the effects of cyclic AMP and calcium-related agents on melatonin output by cultured chick pineal cells, and suggested that changes in calcium influx might act through cyclic AMP. Here, effects of calcium-related agents and manipulations on cyclic AMP (and cyclic GMP) levels are demonstrated directly. These effects support a role for cyclic AMP (but not cyclic GMP) in the effects of changes in calcium influx on melatonin production by these cells.
