The effect of [Dmt¹]DALDA chronic treatment on gene expression in spinal cord

Gene	Saline control	3-Day treatment	7-Day treatment	P
MOR	5.46±0.33	5.00±0.23	5.64±0.43	0.67
DOR	5.95±0.30	5.87±0.26	6.78±0.20	0.11
KOR	6.47±0.27	6.40±0.19	6.64±0.32	0.82
PPE	1.30±0.18	1.06±0.07	1.76±0.36	0.64
PPD	6.77±0.28	6.47±0.19	6.95±0.22	0.86
POMC	9.96±0.34	10.17±0.21	10.16±0.34	0.59

Data are given as mean±s.e.m. of ΔC_T values, n=5. P-value, compared with treatments over time and saline control, was determined by one-way ANOVA analysis.
