This study investigated cadherin-1 (Cdh1) expression in the sensorimotor cortex of rats after spinal cord injury (SCI). The repairing effect of Cdh1 was evaluated by silencing its expression with lentivirus-mediated RNAi. Twenty male Sprague-Dawley (SD) rats were randomly divided into a normal group and an operation group. Rats of the operation group were given SCI by the Allen method (T10-T11). Cdh1 expression in the sensorimotor cortex was examined by quantitative real-time polymerase chain reaction (PCR) and Western blot analysis. Thirty male SD rats were divided into a sham-operation (SO) group, a lentivirus vector (LV) group, and a recombinant lentivirus (RL) group. Rat behavior was evaluated using the Basso-Beattie-Bresnahan (BBB) test every week. Ten days after injection, Cdh1 expression was examined by quantitative real-time PCR and Western blot. Six weeks after injury, animals were injected with biotinylated dextran amine-Texas Red (BDA-TR), and then at 8 weeks, spinal cords were removed and sectioned in serial order. The expression of Cdh1 mRNA was significantly higher in the operation than in the normal group (P < 0.05). The expression of Cdh1 mRNA was lower in the RL than in the SO or LV groups at 10 days after injection (P < 0.05). In addition, the BBB score was higher for the RL than for the SO or LV groups at 6 weeks after injury (P < 0.05). A novel population of BDA-labeled axons was observed extending past the lesion in the RL group, which was rarely observed in the SO and LV groups. These results suggest that the anaphase-promoting complex-Cdh1 may play an important role in inhibiting axonal growth.
