Illustrative diagram of the experiment. Protocol I: Behavioral tests were performed on days 0, 1, 3, 7, 10, and 14 post-SNI. Protein was removed from the L4-6 lumbar enlargement of the spinal cord for biological tests on day 14 post-SNI. Protocol II: A day before SNI, Ad-SIRT2 or Ad-control was injected intrathecally. Behavioral tests were performed on days 0, 1, 3, and 7 post-SNI. Tissue samples were harvested on day 7 post-SNI. SNI: spared nerve injury; IT: intrathecal injection of SIRT2 adenovirus (Ad-SIRT2) or Ad-control; blue arrow: Behavioral test.
