Table 2. Specificity of SIN-1-induced stimulation of taurine uptake.

	Uptake, pmol·mg protein⁻¹·15 min⁻¹
Substrate	Control	SIN-1
Taurine (80 nM)	2.58 ± 0.088(100)	10.65 ± 0.053(413)
Glutamine (50 nM)	5.64 ± 0.388(100)	6.07 ± 0.269(108)
Glutamate (100 nM)	13.75 ± 0.152(100)	13.93 ± 0.583(101)
Carnitine (30 nM)	0.41 ± 0.024(100)	0.37 ± 0.032(90)
Leucine (30 nM)	1.75 ± 0.085(100)	2.08 ± 0.006(118)
Alanine (30 nM)	2.22 ± 0.059(100)	2.44 ± 0.086(110)
Arginine (30 nM)	2.30 ± 0.101(100)	2.08 ± 0.090(90.4)

Values are means ± SE; values in parentheses are percentages of respective control uptake. ARPE-19 cells were treated with or without 1 mM SIN-1 for 24 h, and then uptake of [³H]taurine and other radiolabeled amino acids was measured for 15 min.
