Effects of L-DOPA and BSO 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%)
L-DOPA	3.07 ± 0.2^6-150 (236%)	609 ± 18 (99%)	5.04 ± 0.1^6-150 (239%)
BSO	0.58 ± 0.01^6-150 (45%)	640 ± 8 (104%)	0.91 ± 0.01^6-150 (43%)
L-DOPA & BSO	0.78 ± 0.01^6-160 (60%)	590 ± 17 (96%)	1.32 ± 0.01^6-160 (62%)

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

↵6-150 p < 0.001 versus controls.
↵6-160 p < 0.001 for cultures treated with L-DOPA versus L-DOPA & BSO.
