Project description:This study describes a circulating miRNA signature of unstable angina (UA), which may be used as a novel biomarker for unstable coronary artery disease (CAD). The Taqman low-density miRNA array were used to identify distinct miRNA expression profiles in the plasma of patients with typical UA and angiographically documented CAD (UA group, n = 13) compared to individuals with non-cardiac chest pain (control group, n = 13). EDTA-plasma samples were obtained before the cardiac catheterization procedure.The study included 2 groups that were classified according to angiographic evidence and clinical evaluation of chest pain. Patients with chest pain or discomfort but with angiographic exclusion of coronary atherosclerosis were enrolled in the control group (n = 13). Chest discomfort referred to the following complaints: chest pain, pressure, tightness, or heaviness; pain that radiated to the neck, jaw, shoulders, back, or one or both arms; and persistent shortness of breath. Patients with typical unstable angina (UA) and angiographically documented CAD were enrolled in the UA group (n = 13).

Project description:Acute pain after surgery is still managed insufficiently. One major need is, therefore, the identification of new targets specifically relevant for postoperative pain to develop effective and non-addictive analgesics. To this end, we have used the plantar incision model in male mice and DIA-MS to reveal unprecedented insights into proteome dynamics in dorsal root ganglia (DRG) 24 hours after incision.

Project description:The development of physical dependence and addiction disorders due to misuse of opioid analgesics is a major concern with pain therapeutics. In this study, we developed a mouse model of oxycodone exposure to gain insight into genes and molecular pathways in reward-related brain regions that are affected by prolonged exposure to oxycodone and subsequent withdrawal in the presence or absence of chronic neuropathic pain. RNA-Sequencing (RNA-Seq) and bioinformatic analyses revealed that oxycodone withdrawal alone triggers robust gene expression adaptations in the nucleus accumbens (NAc), medial prefrontal cortex (mPFC), and ventral tegmental area (VTA), with numerous genes and pathways selectively affected by oxycodone withdrawal under peripheral nerve injury states. Our pathway analysis predicted that histone deacetylase 1 (HDAC1), an epigenetic modifier with a prominent role in striatal plasticity, is a top upstream regulator in opioid withdrawal in both the NAc and mPFC. Indeed, treatment with the novel HDAC1/2 inhibitor RBC1HI (Regenacy Brain Class 1 HDAC Inhibitor) attenuated behavioral manifestations of oxycodone withdrawal, with the drug being more efficacious under states of neuropathic pain. Since RBC1HI displays antiallodynic actions in models of neuropathic pain, inhibition of HDAC1/2 may provide an avenue for chronic pain patients dependent on opioids to transition to non-opioid analgesics. Overall, our study highlights transcriptomic events in components of the reward circuitry associated with oxycodone withdrawal under pain-free and prolonged neuropathic pain states, thereby providing information on possible new targets for the treatment of physical dependence to opioids and transitioning individuals to non-opioid medications for chronic pain management.

Project description:Symptoms including pain and discomfort commonly present during ureteral stenting is not well understood. We investigated global changes in ureters at the transcriptional, translational, and functional levels while stents are indwelling and following removal and recovery using a porcine model. Polaris stents (6Fr, Boston Scientific, Natick, MA) were cystoscopically inserted with placement confirmed using fluoroscopy. For proteomics samples, ureters were stented for 14 days and recovered for 7 days and each pig was stented unilaterally so that the contralateral unstented kidney and ureter served as an internal control.

Project description:Neuropathic pain is an apparently spontaneous experience triggered by abnormal physiology of the peripheral or central nervous system, which evolves with time. Neuropathic pain arising from peripheral nerve injury is characterized by a combination of spontaneous pain, hyperalgesia and allodynia. There is no evidence of this type of pain in human infants or rat pups; brachial plexus avulsion, which causes intense neuropathic pain in adults, is not painful when the injury is sustained at birth. Since infants are capable of nociception from before birth and display both acute and chronic inflammatory pain behaviour from an early neonatal age, it appears that the mechanisms underlying neuropathic pain are differentially regulated over a prolonged postnatal period. We used microarrays to detail the global programme of gene expression underlying the differences in nerve injury between along the postnatal development and identified distinct classes of regulated genes during the injury Experiment Overall Design: We have performed a microarray analysis of the rat L4/L5 dorsal root ganglia, 7 days post spared nerve injury, a model of neuropathic pain. Genes that are regulated in adult rats displaying neuropathic behaviour were compared to those regulated in young rats (10 days old) that did not show the same neuropathic behaviour.

Project description:Abstract Objective: Osteoarthritis (OA) is accompanied by severe and debilitating pain that current analgesics are unable to fully alleviate. A multitude of signaling molecules, pathways, and cells have been identified as regulators of OA pain. Fatty acid binding protein 5 (FABP5) regulates pain in other disease states and we hypothesized that it is involved in the regulation of OA pain. Design: This was a combined clinical and pre-clinical study. Human synovial and osteochondral tissues collected during total knee arthroplasty were subjected to immunohistochemical analyses to identify the spatial expression patterns of FAB5, COX1, COX2, and macrophages. In addition, synovial specimens were cultured the presence and absence of SBFI-103, a selective FABP5 inhibitor, and cytokines and chemokines levels were measured. The rat monoiodoacetate (MIA) model of OA was then enlisted to evaluate the efficacy of SBFI-103 in alleviating OA pain. Finally, RNAseq was performed to identify alterations in synovial gene expression in vehicle and SBFI-103 treated MIA rats. Results: FABP5 expression was present in clinical OA tissues, with higher expression seen higher grade OA and no apparent differences between genders. Furthermore, FABP5 staining colocalized with CD14+ cells, indicating a macrophage origin of FABP5. Synovial specimens secreted CCL2, IL6, IL8, CXCL1, MIF, and Serpin E1 in vitro and treatment with SBFI-103 attenuated CCL2, IL6, IL8, and CXCL1, but not MIF and Serpin E1. Twenty-eight days after MIA injection, rats exhibited histological joint degradation and significant incapacitance. Ketoprofen treatment partially reduced incapacitance and naproxen had no effect; however, SBFI-103 showed a dose dependent alleviation of incapacitance that was independent of cannabinoid or PPARα receptor activity. RNAseq analyses identified differential expression of >6,000 transcripts compared to contralateral controls in vehicle treated rats and only 513 after SBFI-103 treatment. Notably, CCL2, CCL7, CCL9, and CXCL1were upregulated in vehicle treated rats, but not those treated with SBFI-103, and this was confirmed with qPCR. Conclusions: Our results show that FABP5 is upregulated in clinical and preclinical OA tissues and that its inhibition lowers pronociceptive signaling and reduces OA pain, indicating that FABP5 inhibitors may constitute a novel class of analgesics to treat OA.

Project description:Nociceptive response belongs to a basic animal behavior facilitating adaptability and survival upon external or internal stimuli. Fish, similarly to higher vertebrates, also possess nociceptive machinery. Current protocols involving procedures performed on adult zebrafish including heart cryoinjury do not, however, take into account the adverse effects including pain that may potentially arise from these methodologies. Here, we assess the effect of two analgesics, lidocaine and morphine, followed after the heart cryoinjury in zebrafish. Monitoring swimming behaviour together with histology and gene expression analysis at the single cell level using scRNA sequencing and RNAscope fluorescent in situ hybridization technology, we show morphine, but not lidocaine, significantly improves animal welfare 6 hours post-cryoinjury, without impairing heart regeneration process. Altogether, morphine should be considered as the analgesic of choice to reduce post-surgical pain in adult zebrafish.

Project description:Patients with chronic illnesses such as Irritable Bowel Syndrome (IBS) or Inflammatory Bowel Disease (IBD) often have reduced quality of life. IBS is characterized by abdominal pain/discomfort associated with altered bowel function, such as diarrhea or constipation, without gross structural changes or inflammation [1]; IBD is characterized by gross inflammation in the gastrointestinal (GI) tract which can result in symptoms such as abdominal pain, cramping, diarrhea and bloody stools. IBS and IBD can profoundly affect quality of life and are influenced by stress and resiliency.The impact of mind-body interventions (MBIs) on IBS and IBD patients has not previously been examined. In this study IBS and IBD patients were enrolled in a 9-week relaxation response based mind-body group intervention (RR-MBI), focusing on elicitation of the RR and cognitive skill building. We performed Peripheral blood transcriptome analysis to identify genomic correlates of the RR-MBI.
