FoxP1 is target gene of miR-9 in adult sensory neurons during axon regeneration. (a) Representative Western blot images of FoxP1 in cultured adult dorsal root ganglion (DRG) neurons three days after transfection of miR-9 mimics. Overexpression of miR-9 leads to decreased FoxP1 protein level. (b) Quantification of FoxP1 level in vitro (normalized to actin, n = 3 for each condition). Error bars represent SEM. **P < 0.01. (c) Representative Western blot images of FoxP1 in cultured adult DRGs in vivo three days after electroporation of miR-9 mimics. (d) Quantification of FoxP1 level in vivo (normalized to actin, n = 3 for each condition). Error bars represent SEM. **P < 0.01.
