2.7.1.137	phosphatidylinositol 3-kinase	nucleus accumbens	shell and core. Cocaine sensitization decreases PI3K activity in nuclear accumbens core. The changes are not normalized following the reversal of cocaine-sensitization. Cocaine-sensitized animals exhibited increased PI3K activity in the nuclear accumbens shell, and this increase is reversed by combined pergolide/ondansetron treatment. Selective enhancement of the PI3K activity in the NAc shell may be one of key alterations underlying the long-term cocaine sensitization	671736

3.4.21.73	u-Plasminogen activator	nucleus accumbens	study on cocaine-induced conditioned-place preference in rats with bilateral intra-accumbens injections of uPA-expressing lentiviral vectors. Overexpression of uPA in the nucleus accumbens significantly augments cocaine-induced place preference. Reinstatement with a low dose of cocaine produces significantly greater preference to the cocaine-associated context. Inhibition of tuPA expression using doxycycline abolishes the augmented acquisition produced by overexpression of uPA but not the expression of the cocaine-induced conditioned-place preference. Cocaine-induced cocaine-induced conditioned-place preference and reinstatement may be dependent on active extracellular uPA	695974
