Comparisons of PTC1 and PTC2 mRNA expression in DRG cells among the normal, PTC1-RNAi, PTC2-RNAi and PTC1/PTC2-RNAi groups. Notes: (a) relative PTC1 mRNA expression in DRG cells among the four groups; (b) relative PTC2 mRNA expression in DRG cells among the four groups; PTC1, Patched 1; PTC2, Patched 2; DRG, dorsal root ganglion; *P<0.05 compared with the normal group.
