The uptake of divalent cations and the intracellular concentration of calcium in PC12 cells were studied by flow cytometric analysis using the calcium-sensitive dye, Fluo-3, under a variety of conditions. In particular the actions of nerve growth factor were analyzed. The data show that nerve growth

โฆ Synopsis
Treatment of PC12 cells with nerve growth factor (NGF) produces a rapid and transient increase in calcium uptake into the cells. The increased uptake is maximal after 5 minutes of NGF treatment, but after 15 minutes of NGF treatment, no such increase can be observed. The effect of NGF is partially inhibited by blockers of L-type calcium channels. K-252a, an alkaloid-like kinase inhibitor that usually is found to inhibit the actions of NGF on PC12 cells, produces an increase in calcium uptake similar to, but smaller than, that seen with NGF. NGF had no effect on calcium release under these conditions.

K-252a treatment produced a 3040% increase in the uptake of radioactive calcium by PC12 cells within 3 4 minutes. The increase in uptake was partially blocked by inhibitors of voltage-operated calcium channels, such as nifedipine, but not by inhibitors of receptor-operated calcium channels, such as

PC12 cells are a nerve growth factor-responsive clone derived from a rat pheochromocytoma. The cells contain catecholamines and secrete them in response to depolarizing stimuli and cholinergic agonists. Treatment of the cells with nerve growth factor produces a number of very rapid changes, includin
Nerve growth factor stimulates the uptake of radioactive calcium into PC12 cells. This stimulation is inhibited by low concentrations of dideoxyforskolin or staurosporine, and by high concentrations of nifedipine or cadmium. On the other hand, neither dideoxyforskolin nor staurosporine inhibited the
