1 Enhancement of morphine analgesia and prevention of morphine tolerance by downregulation of beta-arrestin 2 with antigene RNAs in mice. Morphine arrestin, beta 2 Mus musculus
2 Enhancement of morphine analgesia and prevention of morphine tolerance by downregulation of beta-arrestin 2 with antigene RNAs in mice. Morphine arrestin, beta 2 Mus musculus
3 In this study, antigene RNAs (agRNAs), which could selectively target gene transcription start sites and potently inhibit gene expression, were used to downregulate the expression of beta-arrestin 2 to investigate its effects on morphine analgesia and tolerance in mice. Morphine arrestin, beta 2 Mus musculus
4 Mice treated with beta-arrestin 2 agRNAs showed enhanced analgesic effects in response to morphine and failed to develop antinociceptive tolerance. Morphine arrestin, beta 2 Mus musculus
5 These results suggest that inhibition of beta-arrestin 2 in the brain with specific agRNAs can improve morphine efficacy, and consequently provide us a useful strategy for treatment of chronic intractable pain and morphine tolerance in vivo. Morphine arrestin, beta 2 Mus musculus
6 These results suggest that inhibition of beta-arrestin 2 in the brain with specific agRNAs can improve morphine efficacy, and consequently provide us a useful strategy for treatment of chronic intractable pain and morphine tolerance in vivo. Morphine arrestin, beta 2 Mus musculus
