When exposed to young rats for a period of days, juvenile rats will respond with full parental behavior (FPB: retrieval and grouping of, and crouching over, pups). Because the parental behavior of juveniles is so robust, and because opiates have been shown to be involved in the regulation of parental behavior in adult animals, we examined morphine's ability to disrupt the display of parental be...
Recent epidemiologic studies implying differences in cancer recurrence based on anesthetic regimens raise the possibility that the mu opioid receptor (MOR) can influence cancer progression. Based on our previous observations that overexpression of MOR in human non-small cell lung cancer (NSCLC) cells increased tumor growth and metastasis, this study examined whether MOR regulates growth factor ...
Nerve growth factor (NGF) regulates sensory neuron phenotype by elevated expression of ion channels and receptors contributing to pain. Peripheral opioid antinociception is dependent on sensory neuron mu opioid receptor (MOR) expression, coupling and efficacy. This study investigates the role of NGF in the upregulation of the number and efficacy of sensory MORs rendering sites of painful inflam...
We have previously shown that cinnamoyl derivatives of 14β-amino-17-cyclopropylmethyl-7,8-dihydronormorphinone and 7α-aminomethyl-6,14-endoethanonororipavine have pronounced pseudoirreversible μ opioid receptor (MOR) antagonism. The present communication describes the synthesis and evaluation of fumaroylamino analogues of these cinnamoylamino derivatives together with some related fumaroyl deri...
How neurons coordinate and reprogram multiple neurotransmitter signals is an area of broad interest. Here, we show that substance P (SP), a neuropeptide associated with inflammatory pain, reprograms opioid receptor recycling and signaling. SP, through activation of the neurokinin 1 (NK1R) receptor, increases the post-endocytic recycling of the mu-opioid receptor (MOR) in trigeminal ganglion (TG...
The morphogenesis-related NDR kinase (MOR) pathway regulates morphogenesis in fungi. In spite of the high conservation of its components, impairing their functions results in highly divergent cellular responses depending on the fungal species. The reasons for such differences are unclear. Here we propose that the species-specific connections between cell cycle regulation and the MOR pathway cou...
Previously, we reported the presence of dual (distal and proximal) promoters in mouse mu-opioid receptor (mor) gene, with mor transcription in mouse brain predominantly initiated by the proximal promoter. Sp factors, bound to double-stranded (ds) cis-regulatory elements, are critical for proximal promoter activity. Here, we further report that a single-stranded (ss) cis-regulatory element and t...
Opioid abuse has been shown to exacerbate the immunosuppressive effects and pathogenesis of HIV infection. The mu opioid receptor (MOR) is present on immune cells, such as macrophages, and mediates the direct immunomodulatory effects of opioids. Through its surface glycoprotein, gp120, HIV-1 binds to surface receptors on target cells, including macrophages, to exert its pathological effects. Bi...
We have identified four new mu-opiod receptor (MOR)-1 exons, indicating that the gene now contains at least nine exons spanning more than 200 kilobases. Replacement of exon 4 by combinations of the new exons yields three new receptors. When expressed in Chinese hamster ovary cells, all three variants displayed high affinity for mu-opioid ligands, but kappa and delta drugs were inactive. However...
