NAc SIRT1 (120kDa) (A) and SIRT2 (43kda) (C) protein levels and correlation to CPP scores (B & D). CPu SIRT1 (120kda) (E) and SIRT2 (43kda) (F) protein levels and correlation to CPP scores (G & H). Protein levels are expressed as a ratio to their respective α tubulin levels (55 kDa) (±SEM) (n = 4–5 animals per group). *Significant difference at p <0 .05. ^Significant differences from cocaine only treated rats (Sal-Coc) at p < 0.05.
