Effects of apomorphine and NGF on GSH synthesis

	GSH	Protein	GSH
	μg/well		μg/mg protein
Controls	1.3 ± 0.04 (100%)	615 ± 4.4 (100%)	2.11 ± 0.02 (100%)
Apomorphine	16.41 ± 0.8^4-150 (1262%)	523 ± 2.0 (92%)	31.37 ± 0.9^4-150 (1487%)
NGF	2.19 ± 0.2^4-150 (169%)	701 ± 7.0^4-160 (114%)	3.12 ± 0.1^4-150 (148%)
Apomorphine & NGF	18.1 ± 0.5 (1391%)	547 ± 2.0 (89%)	33.10 ± 1.20 (1569%)

Five days after plating, cultures were exposed to 50 μmL-DOPA, 10 μm apomorphine, or 50 ng/ml NGF for 24 hr. The cultures were then assayed for total GSH and protein levels. Data are mean ± standard error (n = 6).
