G9a overexpression during prior cocaine SA leads to selective increases in foot-shock stress-induced reinstatement. Shown are paired lever presses over 5 d of extinction in 3 h sessions (HSV-GFP: n = 7, HSV-G9a: n = 10; a), after noncontingent light and tone cue presentation (HSV-GFP: n = 6, HSV-G9a: n = 7; b), after intraperitoneal injections of saline or cocaine (HSV-GFP: n = 6, HSV-G9a: n = 9; c), or subsequent to intermittent foot shocks for 30 min (HSV-GFP: n = 6, HSV-G9a: n = 7; d). Data are expressed as mean ± SEM. *p < 0.05 compared with HSV-GFP.
