CSPGs alter levels of miRNAs and proteins in distal axons. Quantitative RT-PCR and Western blot analysis show increased miRNAs (A) and reduced proteins (B), respectively; and decreased miRNAs (C) and augmented proteins (D), respectively, in distal axons treated with CSPGs compared to control group without the CSPGs treatment. *p<0.05, and **p<0.01, n=3/group.
