Protein and mRNA levels of the cAMP/PKA pathway related molecules. (A) The protein levels of CREB, eIF-2, actin, MAP1A, MAP1B, MAP2, MAP4, and Tau in the lumbar disc. (B-I) Quantitative graphs representing the relative protein levels. (J-Q) The mRNA levels of CREB, eIF-2, actin, MAP1A, MAP1B, MAP2, MAP4, and Tau in the lumbar disc. Data are expressed as the mean ± SD. **P < 0.01, compared with the sham group; ##P < 0.01, compared with the model group
