The expression of netrin receptor mRNAs in the adult DRG Dcc and unc5h1-4 mRNA levels in the adult DRG and spinal cord were evaluated using RT-PCR analysis, and PCR amplification of GAPDH was used as a control. unc5h1-3 mRNAs were expressed in the adult DRG, whereas dcc and unc5h4 mRNAs were not. The values in the right column shows the signal intensity normalized on the basis of the PCR amplification of GAPDH. The values indicate the low levels of unc5h mRNA expression in the DRG as compared to those in the spinal cord. SC; spinal cord, DRG; dorsal root ganglion.
