Ratio of phosphorylated cAMP response element-binding protein (p-CREB) to CREB in Achilles tendon. Upper panel: representative expressions of p-CREB and CREB. Lower panel: relative expression of p-CREB to CREB. A, control group; B, Achilles tendon injury group; C, Achilles tendon injury and 2 mg/kg PDRN-applied group; D, Achilles tendon injury and 4 mg/kg PDRN-applied group; E, Achilles tendon injury and 8 mg/kg PDRN-applied group. PDRN, polydeoxyribonucleotide. *P<0.05 compared with the control group. #P<0.05 compared with the Achilles tendon injury group.
