Neuroblastoma cells were used to examine the effect of chronic exposure to increased concentrations of glucose, galactose, or L-fucose on bradykinin-stimulated intracellular calcium release using the calcium indicator fluo-3. Bradykinin caused a concentration dependent increase in the intracellular calcium concentration and phosphoinositide hydrolysis in neuroblastoma cells. Norepinephrine, carbachol, serotonin, and thapsigargin also increased the calcium concentration. Treatment of the cells with 10(-6) M bradykinin exhausts calcium release such that the successive treatment of the cells with norepinephrine, carbachol, or serotonin results in no secondary response. In contrast, bradykinin treatment of the cells following exposure to norepinephrine, carbachol, or serotonin caused a secondary increase in calcium release. These results suggest that several hormone responsive calcium pools may exist in neuroblastoma cells or that norepinephrine, carbachol, or serotonin may not fully stimulate calcium release. Bradykinin-stimulated calcium release is not effected by chronic exposure of the cells to increased concentrations of glucose, galactose, or L-fucose. Suggesting that hormone-stimulated calcium release is not an abnormality that develops in neural cells exposed to conditions that mimic the diabetic milieu. In addition, these studies provide evidence that fluo-3 is a good fluorescent indicator for the study of calcium mobilization in cultured neuroblastoma cells.
