Title Analgesia of naloxone and morphine in wild-type and NY1DD sickle cell mice using BMAP cDNA microarrays
Organism Mus musculus
Experiment type Expression profiling by array
Summary Sickle cell disease is the most common genetic disorder in African-Americans. The opioid analgesic, morphine, has long been the treatment for the severe pain associated with this disease. Here we reveal that the opioid antagonist, naloxone, possesses potent analgesic activity in two strains of sickle cell mice (NY1DD and hBERK1) and not in their respective controls (ICR-CD1 and C57BL/6J) when administered by three parenteral routes. In the NY1DD sickle mice, naloxone (i.c.v.) possessed ~300-fold greater potency than morphine (i.c.v.). Other opioid antagonists (naltrexone, norbinaltorphimine, naltrindole) were substantially less effective in producing analgesia. Naloxone and morphine were synergistic in NY1DD mice, suggesting that analgesia was mediated via different receptor systems. Since microarray analysis suggested naloxone-induced down-regulation of the CCR5 chemokine receptor in NY1DD mice but not in control mice, the role of its endogenous ligand, CCL5 (RANTES), was investigated.
Keywords: Comparison of drug induced gene expression
 
Overall design In total 12 samples were analyzed. We used two strains of mice:
Wild-type: C57BL/6J
Sickle cell: NY1DD

To compare the gene expression patterns of naloxone and morphine, 4 treatments were used:
i) Naloxone on sickle cell mice - 3 replicates
ii) Morphiine on sickle cell mice - 3 replicates
iii) Naloxone on wild-type mice - 3 replicates
iv) Morphine on wild-type mice - 3 replicates

As we used dual channel cDNA microarrays, the experimental (Cy5) channel was used for the drugs (either morphine or naloxone) and the control (Cy3) was always saline treated.
