Changes of nitric oxide associated gene expressions by microarray analysis at week 4

Group	M/C	S/M
NOS1	1.15±0.02*	0.52±0.03†
NOS2	1.01±0.04	1.11±0.02
NOS3	1.12±0.04	0.87±0.03†

M, monocrotaline; C, control; S, simvastatin; NOS1, neuronal nitric oxide synthase; NOS2, inducible nitric oxide synthase; NOS3, endothelial nitric oxide synthase.
^*P<0.05 vs. the corresponding value in the C group.
^†P<0.05 vs. the corresponding value in the M group.
