a,d,g, Venn diagrams depicting overlap of genes altered by oxycodone withdrawal under SNI-Oxy versus SNI-Sal and in Sham-Oxy versus Sham-Sal conditions in the NAc (a), mPFC (d) and VTA (g). These graphs also show respective union heat maps of commonly regulated DEGs between SNI-Oxy versus SNI-Sal and Sham-Oxy versus Sham-Sal conditions in the NAc, mPFC and VTA, as well as associated GO terms or predicted drug targets. b,c,e,f,h,i, Top predicted URs of Sham-Oxy versus Sham-Sal and SNI-Oxy versus SNI-Sal DEGs in the NAc (b and c), mPFC (e and f) and VTA (h and i). Top predicted URs of SNI-Oxy versus Sham-Sal control DEGs in NAc, mPFC and VTA.
