TY - JOUR T1 - COcaine addiction AU - Kuehn BM Y1 - 2010/02/24 N1 - 10.1001/jama.2010.166 JO - JAMA SP - 722 EP - 722 VL - 303 IS - 8 N2 - Previous studies have demonstrated that repeated cocaine administration leads to persistent changes both in gene expression and in the structure of the nucleus accumbens of the brain. Now a multi-institutional team of scientists has demonstrated, through a series of experiments in mice, that repeated cocaine administration suppresses the activity of G9A, an enzyme that helps regulate whether genes are turned on or off (Maze I et al.
