The expression of α-CGRP and SP precursor (preprotachykinin-A, PPT-A) mRNA in dorsal root ganglia (DRGs) and spinal cord tiussue. In these experiments C57BL/6 mice were opioid naïve or treated chronically with morphine or morphine and butoxamine. Panel A provides the data from assays of αCGRP. Panel B provides data of PPT-A. N=6 mice for each group. Data are expressed as the means ± S.E.M. *P<0.05; **P<0.01.
