Up-regulation of oxytocin receptors on peripheral sensory neurons mediates analgesia in chemotherapy-induced neuropathic pain. Br J Pharmacol 2023. [PMID: 36702458 DOI: 10.1111/bph.16042] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 01/19/2023] [Accepted: 01/22/2023] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND AND PURPOSE Chemotherapy-induced neuropathic pain (CINP) currently has limited effective treatment. Although the roles of oxytocin (OXT) and the oxytocin receptor (OXTR) in central analgesia have been well documented, the expression and function of OXTR in the peripheral nervous system remain unclear. Here, we evaluated the peripheral antinociceptive profiles of OXTR in CINP. EXPERIMENTAL APPROACH Paclitaxel (PTX) was used to establish CINP. Quantitative real-time polymerase chain reaction (qRT-PCR), in situ hybridization, and immunohistochemistry were used to observe OXTR expression in dorsal root ganglia (DRG). The antinociceptive effects of OXT were assessed by hot-plate and von Frey tests. Whole-cell patch clamp was performed to record sodium currents, excitability of DRG neurons, and excitatory synapse transmission. KEY RESULTS Expression of OXTR in DRG neurons was enhanced significantly after PTX treatment. Activation of OXTR exhibited antinociceptive effects, by decreasing the hyperexcitability of DRG neurons in PTX-treated mice. Additionally, OXTR activation up-regulated the phosphorylation of protein kinase C (pPKC) and, in turn, impaired voltage-gated sodium currents, particularly the voltage-gated sodium channel 1.7 (NaV 1.7) current, that plays an indispensable role in PTX-induced neuropathic pain. OXT suppressed excitatory transmission in the spinal dorsal horn as well as excitatory inputs from primary afferents in PTX-treated mice. CONCLUSION AND IMPLICATIONS The OXTR in small-sized DRG neurons is up-regulated in CINP and its activation relieved CINP by inhibiting the neural excitability by impairment of NaV 1.7 currents via pPKC. Our results suggest that OXTR on peripheral sensory neurons is a potential therapeutic target to relieve CINP.

Differential expression of H19, BC1, MIAT1, and MALAT1 long non-coding RNAs within key brain reward regions after repeated morphine treatment. Behav Brain Res 2021; 414:113478. [PMID: 34302875 DOI: 10.1016/j.bbr.2021.113478] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 05/22/2021] [Accepted: 07/19/2021] [Indexed: 12/14/2022]
Abstract
Morphine-induced analgesic tolerance and dependence are significant limits of pain control; however, the exact molecular mechanisms underlying morphine tolerance and dependence have remained unclear. The role of long non-coding RNAs (lncRNAs) in morphine tolerance and dependence is yet to be determined. We aimed to explore the association of specific lncRNAs expression in key brain reward regions after repeated injection of morphine. Male Wistar rats received subcutaneous injections of twice-daily morphine (10 mg/kg) or saline (1 mL/kg) for eight days. On day 8 of the repeated injections, induction of morphine analgesic tolerance and dependence was confirmed through a hotplate test and a naloxone-precipitated withdrawal analysis, respectively. Expression of H19, BC1, MIAT1, and MALAT1 lncRNAs was determined from the midbrain, striatum, hypothalamus, prefrontal cortex (PFC), and hippocampus by real-time PCR on day 8 of the repeated injections. The H19 expression was significantly different between morphine-treated and control saline-treated rats in all investigated areas except for the hippocampus. The BC1 expression significantly altered in the midbrain, hypothalamus, and hippocampus, but not in the striatum and PFC after repeated morphine treatment. The MIAT1 and MALAT1 expression site-specifically altered in the midbrain, hypothalamus, and striatum; however, no significant changes were detected in their expression in the PFC and hippocampus after repeated morphine treatment. We conclude that alterations in the expression of these lncRNAs in the brain reward regions especially in the midbrain, striatum and hypothalamus may have critical roles in the development of morphine dependence and tolerance, which need to be considered in future researches.

Abstract
Purpose: Morphine is often used for the treatment of moderate and severe cancer pain,
but long-term use can lead to morphine tolerance. Methods for effectively
inhibiting morphine tolerance and the related mechanism of action are of
great significance for the treatment of cancer pain. Previous studies have
shown that electroacupuncture (EA) can inhibit the occurrence of morphine
tolerance, but the mechanism is not yet clear. The aim of the present study
was to explore the signaling pathway by which EA attenuates the development
of bone cancer pain (BCP)-morphine tolerance (MT). Materials and methods: Changes in the paw withdrawal threshold (PWT) of rats with bone cancer
pain-morphine tolerance were observed in a study of EA combined with
intrathecal injection of a PI3K inhibitor (LY294002) or agonist
(insulin-like growth factor-1 [IGF-1]). We also tested the protein
expression of phosphorylated phosphatidylinositol 3-kinase (p-PI3K),
phosphorylated protein kinase B (p-Akt), phosphorylated c-Jun
NH2-terminal kinase 1/2 (p-JNK1/2), and β-arrestin2 in the L4-6
spinal dorsal horn of rats. Results: The protein expression of p-PI3K, p-Akt, p-JNK1/2, and β-arrestin2 was
upregulated in the L4-6 spinal dorsal horn of rats with bone cancer pain and
bone cancer pain-morphine tolerance. EA delayed the occurrence of morphine
tolerance in rats with bone cancer pain and downregulated the protein
expression of p-PI3K, p-Akt, p-JNK1/2, and β-arrestin2 in the L4-6 spinal
dorsal horn of rats with bone cancer pain-morphine tolerance. Intrathecal
injection of LY294002 attenuated the development of morphine tolerance and
downregulated the protein expression of p-Akt, p-JNK1/2, and β-arrestin2 in
the spinal dorsal horn of rats with bone cancer pain-morphine tolerance. In
addition, the inhibitory effect of EA on morphine tolerance was reversed by
IGF-1. Conclusion: The mechanism underlying the ability of EA to attenuate morphine tolerance
may be associated with inhibition of the PI3K/Akt/JNK1/2 signaling
pathway.

Ahmadi S, Miraki F, Rostamzadeh J. Association of morphine-induced analgesic tolerance with changes in gene expression of GluN1 and MOR1 in rat spinal cord and midbrain. IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2016; 19:924-931.

Abstract
OBJECTIVES We aimed to examine association of gene expression of MOR1 and GluN1 at mRNA level in the lumbosacral cord and midbrain with morphine tolerance in male Wistar rats. MATERIALS AND METHODS Analgesic effects of morphine administrated intraperitoneally at doses of 0.1, 1, 5 and 10 mg/kg were examined using a hot plate test in rats with and without a history of 15 days morphine (10 mg/kg) treatment. Morphine-induced analgesic tolerance was also assessed on days 1, 5, 10 and 15 of chronic morphine injections. Two groups with history of 15 days injections of saline or morphine (10 mg/kg) were decapitated on day 15 and their lumbosacral cord and midbrain were dissected for evaluating MOR1 and GluN1 gene expression. RESULTS The results of the hot plate test showed that morphine (5 and 10 mg/kg) induced significant analgesia in naïve rats but its analgesic effects in rats receiving 15 days injections of morphine (10 mg/kg) was decreased, indicating tolerance to morphine analgesia. The results also showed that the GluN1 gene expression in tolerant rats was decreased by 71% in the lumbosacral cord but increased by 110 % in the midbrain compared to the control group. However, no significant change was observed for the MOR1 gene expression in both areas. CONCLUSION It can be concluded that tolerance following administration of morphine (10 mg/kg) for 15 days is associated with site specific changes in the GluN1 gene expression in the spinal cord and midbrain but the MOR1 gene expression is not affected.
