Morphine effects on striatal transcriptome in mice

Table 1 Summary of genotype-dependent differences in striatal gene expression profile between mouse strains

The mouse strains evaluated were 129P3/J, C57BL/6J, DBA/2J, and SWR/J. ^aFold change over mean mRNA level from all four strains for 3,457 significantly different probe sets. Relative expression levels were computed from MBEI perfect match/mismatch (PM/MM) data. ^bTotal numbers of probe sets are presented. In addition, numbers of transcripts with increased level comparing to mean are included in parentheses.
