Effects of naloxone on NSC proliferation and differentiation

ABSTRACT: Naloxone is an opioid-receptor antagonist used to reverse the effects of opioid.In our study, we treated NSCs (neural stem cells) with naloxone and damgo (a selective μopioid receptor agonist), and examined their effects on NSCs proliferation and differentiation.Naloxone was found to promote NSCs proliferation and neural differentiation, while the effects of damgo was very week. The results suggested that naloxone may work indepedent of opioid receptors. To investigate the underlying mechanisms, RNA-seq was conducted. For proliferation analysis,p8 NSCs were cultured with or without naloxone or damgo for 3 days. For differentiation analysis,p8 NSCs was induced to differentiate with or without naloxone or damgo, samples on D2 were collected and analyzed.

DNA methylation maps of mouse NSCs treated with naloxone

Project description:In our study,we examined the effects of naloxone (an opioid receptor antagonist) on NSCs (neural stem cells) proliferation and differenntiation. Briefly, we treated NSCs with naloxone in the proliferation and differentiation system. Naloxone was shown to acclerate NSCs proliferation and increase neural differentiation.To investigate how DNA methylation is affected upon naloxone treatment, cells cultured 3 days with naloxone and cells differentiated with naloxone at D2 were collected, genomic DNA was extracted and subjected to RRBS analysis.

Analgesia of naloxone and morphine in wild-type and NY1DD sickle cell mice using BMAP cDNA microarrays

Project description: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.

NSC-derived exosomes enhance therapeutic effects of NSC transplantation on cerebral ischemia in mice

Project description:Transplantation of neural stem cells (NSCs) has been proved to promote functional rehabilitation of brain lesions including ischemic stroke. However, the therapeutic effects of NSC transplantation is limited by the low survival and differentiation rates of NSCs due to the harsh environment in the brain after ischemic stroke. Here, we employed NSCs derived from human induced pluripotent stem cells (iPSCs) together with exosomes extracted from NSCs to treat cerebral ischemia induced by middle cerebral artery occlusion/reperfusion (MCAO/R) in mice. The results showed that NSC-derived exosomes significantly reduced the inflammatory response, alleviated oxidative stress after NSC transplantation, and facilitated NSCs differentiation in vivo. The combination of NSCs with exosomes ameliorated the injury of brain tissue including cerebral infarct, neuronal death and glial scarring, and promoted the motor function recovery. To explore the underlying mechanisms, we analyzed the miRNA profiles of NSC-derived exosomes and the potential downstream genes. Our study provided the rationale for the clinical application of NSC-derived exosomes as a supportive adjuvant for NSC transplantation after stroke.

Compare miRNA expression profiles of human iNSC, H9-NSC, fibroblast

Project description:miRNA profiling of human H9-derived neural stem cells (H9-NSCs) comparing control human adult dermal fibroblasts (hDFs), SOX2-transduced human induced neural stem cells (hDF-iNSC (SOX2)), SOX2/HMGA2-transduced human induced neural stem cells (hDF-iNSC (SOX2/HMGA2)). Goal was to determine the global miRNA expression between the groups. H9-NSC vs hDF vs hDF-iNSC(SOX2) vs hDF-iNSC(SOX2/HMGA2)
