Figure 3: Time course of changes in p-ERK protein levels in the NAcc after cocaine administration in male and female rats. The p-ERK protein levels are expressed as mean ± SEM values, normalized to α-tubulin levels, 0 to 90 minutes after cocaine administration in (A) male and (B) female rats. Lower panels contain representative immunoblots of PKA and α-tubulin.
* Represents significant differences as compared with saline-treated controls; p < 0.05. White bars represent levels of saline-treated groups. Shaded bars represent levels of cocaine-treated groups. N = 4 per group.
