Qin S, Liu D. Long non-coding RNA H19 mediates osteogenic differentiation of bone marrow mesenchymal stem cells through the miR-29b-3p/DKK1 axis. J Cell Mol Med 2024; 28:e18287. [PMID: 38685675 PMCID: PMC11058329 DOI: 10.1111/jcmm.18287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 03/20/2024] [Accepted: 03/25/2024] [Indexed: 05/02/2024] Open
Abstract
Single immobilization theory cannot fully account for the extensive bone loss observed after spinal cord injury (SCI). Bone marrow mesenchymal stem cells (BMSCs) are crucial in bone homeostasis because they possess self-renewal capabilities and various types of differentiation potential. This study aimed to explore the molecular mechanism of long non-coding RNA H19 in osteoporosis after SCI and provide new research directions for existing prevention strategies. We used small interfering RNA to knockdown H19 expression and regulated miR-29b-2p expression using miR-29b-3p mimetics and inhibitors. Western blotting, real-time fluorescence quantitative PCR, Alizarin red staining, alkaline phosphatase staining and double-luciferase reporter gene assays were used to assess gene expression, osteogenic ability and binding sites. lncRNA H19 was upregulated in BMSCs from the osteoporosis group, whereas miR-29b-3p was downregulated. We identified the binding sites between miR-29b-3p and lncRNAs H19 and DKK1. H19 knockdown promoted BMSCs' osteogenic differentiation, whereas miR-29b-3p inhibition attenuated this effect. We discovered potential binding sites for miR-29b-3p in lncRNAs H19 and DKK1. Our findings suggest that long non-coding RNA H19 mediates BMSCs' osteogenic differentiation in osteoporosis after SCI through the miR-29b-3p/DKK1 axis and by directly inhibiting the β-catenin signalling pathway.

[PMID: 37291666 PMCID: PMC10251601 DOI: 10.1186/s40779-023-00461-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Accepted: 06/01/2023] [Indexed: 06/10/2023] Open
Abstract
Spinal cord injury (SCI) is a devastating and disabling medical condition generally caused by a traumatic event (primary injury). This initial trauma is accompanied by a set of biological mechanisms directed to ameliorate neural damage but also exacerbate initial damage (secondary injury). The alterations that occur in the spinal cord have not only local but also systemic consequences and virtually all organs and tissues of the body incur important changes after SCI, explaining the progression and detrimental consequences related to this condition. Psychoneuroimmunoendocrinology (PNIE) is a growing area of research aiming to integrate and explore the interactions among the different systems that compose the human organism, considering the mind and the body as a whole. The initial traumatic event and the consequent neurological disruption trigger immune, endocrine, and multisystem dysfunction, which in turn affect the patient's psyche and well-being. In the present review, we will explore the most important local and systemic consequences of SCI from a PNIE perspective, defining the changes occurring in each system and how all these mechanisms are interconnected. Finally, potential clinical approaches derived from this knowledge will also be collectively presented with the aim to develop integrative therapies to maximize the clinical management of these patients.

Abstract
Context/objective: To identify themes of interest for the production of educational resources for people with spinal cord injury (SCI).Design: A mixed-method study.Setting: Outpatient SCI community in Australia.Participants: Individuals with a SCI, or carers, family & friends of people who live with a SCI (n = 116).Interventions: Not applicable.Outcome measures: Quantify themes of interest perceived within the Australian SCI community as necessary for the development of SCI educational resources.Results: All seven individuals from the focus-group interviews suggested that educational resources on body physiology, secondary complications, injury pathophysiology, and health and wellbeing maintenance would be most pertinent for development. These themes (among others) were further explored and quantitatively evaluated via an online survey which demonstrated that interviewees ranked 'Your injury' as being of highest importance for the production of educational resources. Within each theme, the sub-categories; 'Bowel/bladder' and 'What equipment is covered in the National Disability Insurance Scheme (NDIS)' were ranked as being of highest importance for the production of educational resources.Conclusion: We have identified multiple areas of interest in the design and production of educational resources for individuals with SCI.

Go Virtual to Get Real: Virtual Reality as a Resource for Spinal Cord Treatment. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18041819. [PMID: 33668438 PMCID: PMC7918193 DOI: 10.3390/ijerph18041819] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 02/08/2021] [Accepted: 02/09/2021] [Indexed: 02/05/2023]
Abstract
Increasingly, refined virtual reality (VR) techniques allow for the simultaneous and coherent stimulation of multiple sensory and motor domains. In some clinical interventions, such as those related to spinal cord injuries (SCIs), the impact of VR on people's multisensory perception, movements, attitudes, and even modulations of socio-cognitive aspects of their behavior may influence every phase of their rehabilitation treatment, from the acute to chronic stages. This work describes the potential advantages of using first-person-perspective VR to treat SCIs and its implications for manipulating sensory-motor feedback to alter body signals. By situating a patient with SCI in a virtual environment, sensorial perceptions and motor intention can be enriched into a more coherent bodily experience that also promotes processes of neural regeneration and plasticity. In addition to the great potential of research, the most significant areas of interest concern is managing neuropathic pain, motor rehabilitation, and psychological well-being.

Resveratrol-primed exosomes strongly promote the recovery of motor function in SCI rats by activating autophagy and inhibiting apoptosis via the PI3K signaling pathway. Neurosci Lett 2020; 736:135262. [PMID: 32682847 DOI: 10.1016/j.neulet.2020.135262] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 06/24/2020] [Accepted: 07/15/2020] [Indexed: 12/14/2022]
Abstract
Spinal cord injury (SCI) is a traumatic condition of the central nervous system (CNS) that can cause paralysis of the limbs. The molecular mechanisms of neural repair following SCI remain unclear and no effective treatment for SCI currently exists, since drugs have difficulty crossing the blood-brain barrier (BBB). The present study aimed to investigate whether exosomes could be used as specific carriers of resveratrol for induction of neuronal autophagy both in vitro and in vivo for the treatment of SCI. The results indicate that exosomes are able to enhance the solubility of resveratrol and enhance penetration of the drug through the BBB, thereby increasing its concentration in the CNS. Exosomes derived from resveratrol-treated primary microglia (Exo + Res) assisted the rehabilitation of paralyzed limbs in rats. Restoration of neural function following SCI was mediated through increased induction of autophagy and inhibition of apoptosis of neurons both in vitro and in vivo via activation of the PI3K signaling pathway. The mechanism of action of Exo + Res may be associated with the PI3K inhibitor 3-methyladenine (3-MA) in primary spinal neurons. The results suggest that Exo + Res are highly effective at crossing the BBB with good stability, suggesting they have potential for enhancing targeted drug delivery and the recovery of neuronal function in SCI therapy, likely associated with the induction of autophagy and inhibition of apoptosis via the PI3K signaling pathway.

Abstract
Spinal cord injury is an uncommon condition, potentially causing a wide range of consequences and requiring specialist rehabilitation to optimize health, activity and participation. Early psychological response to injury and relations with staff, as well as family, may set the foundations for long-term emotional adjustment, healthcare utilization and quality of life. The Stanmore Nursing Assessment of Psychological Status has been developed at the London Spinal Cord Injury Centre to empower nurses to adopt a consistently empathic approach to patient care, as part of a comprehensive range of rehabilitation team skills. Its use in other spinal cord injury centers and a broader range of clinical environments (hospital and community) should therefore be considered.
