RGS2 mRNA expression in vascular smooth muscle cells

Endogenously expressed RGS2 mRNA levels were determined by using real-time PCR assays. Only overnight treatment with 10 μM MG-132 had significant effects on RGS2 mRNA expression. Fold values are expressed relative to control values.

Treatment	RGS2 mRNA Level
	3 h	Overnight
	fold
100 nM Digoxin		1.31 ± 0.71
100 nM Ouabain		0.91 ± 0.17
10 μM Lactacystin	0.80 ± 0.06	1.94 ± 1.92
10 μM MG-132	0.56 ± 0.15	10.07 ± 5.12***
