From Table 2 and Figure 3A it can be seen that, relative to alcoholics and controls, cocaine addicts showed significant or trend down-regulation of GPHN (p = 0.02), NSF (p<0.001) (Figure S2), ZDHHC3 (p = 0.056) and UBQLN1 (p = 0.062). Alcoholics had increased expression of GABARAP relative to cocaine addicts (p = 0.021).
