Reducing polypyrimidine tract‑binding protein 1 fails to promote neuronal transdifferentiation on HT22 and mouse astrocyte cells under physiological conditions. Exp Ther Med 2024; 27:72. [PMID: 38234625 PMCID: PMC10792410 DOI: 10.3892/etm.2023.12360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Accepted: 11/27/2023] [Indexed: 01/19/2024] Open
Abstract
In contrast to prior findings that have illustrated the conversion of non-neuronal cells into functional neurons through the specific targeting of polypyrimidine tract-binding protein 1 (PTBP1), accumulated evidence suggests the impracticality of inducing neuronal transdifferentiation through suppressing PTBP1 expression in pathological circumstances. Therefore, the present study explored the effect of knocking down PTBP1 under physiological conditions on the transdifferentiation of mouse hippocampal neuron HT22 cells and mouse astrocyte (MA) cells. A total of 20 µM negative control small interfering (si)RNA and siRNA targeting PTBP1 were transfected into HT22 and MA cells using Lipo8000™ for 3 and 5 days, respectively. The expression of early neuronal marker βIII-Tubulin and mature neuronal markers NeuN and microtubule-associated protein 2 (MAP2) were detected using western blotting. In addition, βIII-tubulin, NeuN and MAP2 were labeled with immunofluorescence staining to evaluate neuronal cell differentiation in response to PTBP1 downregulation. Under physiological conditions, no significant changes in the expression of βIII-Tubulin, NeuN and MAP2 were found after 3 and 5 days of knockdown of PTBP1 protein in both HT22 and MA cells. In addition, the immunofluorescence staining results showed no apparent transdifferentiation in maker levels and morphology. The results suggested that the knockdown of PTBP1 failed to induce neuronal differentiation under physiological conditions.

Abstract
Central nervous system injuries and diseases, such as ischemic stroke, spinal cord injury, neurodegenerative diseases, glioblastoma, multiple sclerosis, and the resulting neuroinflammation often lead to death or long-term disability. MicroRNAs are small, non-coding, single-stranded RNAs that regulate posttranscriptional gene expression in both physiological and pathological cellular processes, including central nervous system injuries and disorders. Studies on miR-124, one of the most abundant microRNAs in the central nervous system, have shown that its dysregulation is related to the occurrence and development of pathology within the central nervous system. Herein, we review the molecular regulatory functions, underlying mechanisms, and effective delivery methods of miR-124 in the central nervous system, where it is involved in pathological conditions. The review also provides novel insights into the therapeutic target potential of miR-124 in the treatment of human central nervous system injuries or diseases.

Jalali H, Golchin H, Sadri Z, Karimzadeh Bardei L, Nabiuni M. Selenium enhances the expression of miR-9, miR-124 and miR-29a during neural differentiation of bone marrow mesenchymal stem cells. J Trace Elem Med Biol 2022; 69:126898. [PMID: 34800856 DOI: 10.1016/j.jtemb.2021.126898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 06/22/2021] [Accepted: 11/02/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Selenium (Se) is a trace element that plays important role in antioxidant defense in the brain. Sodium selenite (Na2SeO3) is an inorganic salt of Se which has an antioxidant function. In the present study, we investigated the effect of Sodium selenite on the expression of important neuronal microRNAs during neural differentiation of bone marrow-derived stem cells (BMSCs). METHODS Mesenchymal stem cells were collected from rat bone marrow and cultured in the Dulbecco's Modified Eagle Medium (DMEM) medium. 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay was conducted to determine the toxicity of Na2SeO3. For neural induction, BMSCs were divided into control, Na2SeO3 containing (10 ng/mL) and Na2SeO3 free groups and cultured in DMEM medium supplemented with Isobutyl-l-methylxanthine (IBMX), Fibroblast growth factor 2 (FGF2), B27, Retinoic acid, and brain derived neurotrophic factor (BDNF) for 14 days. At the end of the differentiation, immunostaining against Microtubule associated protein 2 (Map-2) and Choline acetyltransferase (ChAT) proteins was performed. Also, the total RNA is extracted from control and neural differentiated cells using a special kit, and the expression of miR-9, miR-124, and miR-29a was analyzed using real-time polymerase chain reaction (RT-PCR). RESULTS Increasing Na2SeO3 concentrations had increasing toxicity; therefore, the concentration of 10 ng/mL was used as a supplement during neural differentiation. Examination of the expression of Map-2 and ChAT proteins showed that Na2SeO3 increased the expression of them and consequently the neuronal differentiation of BMSCs. Na2SeO3 also significantly increased the expression of miR-9, miR-124, and miR-29a in BMSCs undergoing neuronal differentiation. CONCLUSIONS Our results suggest that the protective effect of selenium on neural differentiation of stem cells may be mediated through neuron specific microRNAs. This result further highlights the importance of selenium supplementation in preventing neuronal diseases.

Abstract
Mesenchymal stem cells (MSCs) have become a promising tool for neurorestorative therapy of neurodegenerative diseases (NDDs), which are mainly characterized by the progressive and irreversible loss of neuronal structure and function in the central or peripheral nervous system. Recently, studies have reported that genetic manipulation mediated by noncoding RNAs (ncRNAs) can increase survival and neural regeneration of transplanted MSCs, offering a new strategy for clinical translation. In this review, we summarize the potential role and regulatory mechanism of two major types of ncRNAs, including microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), during the neurogenesis of MSCs with gene expression profile analyses. We also overview the realization of MSC-based therapy mediated by ncRNAs in the treatment of spinal cord injury, stroke, Alzheimer's disease and peripheral nerve injury. It is expected that ncRNAs will become promising therapeutic targets for NDD on stem cells, while the underlying mechanisms require further exploration.

Abstract
With no permanent cure for neurodegenerative diseases, the symptoms reappear shortly after the withdrawal of medicines. A better treatment outcome can be expected if the damaged neurons are partly replaced by functional neurons and/or they are repaired using trophic factors. In this regard, safe cell therapy has been considered as a potential alternative to conventional treatment. Here, we have described a two-stage culture process to differentiate Wharton Jelly mesenchymal stem cells (WJ-MSCs) into neuronal-like cells in the presence of various cues involved in neurogenesis. The fate of cells at the end of each stage was analyzed at the morphometric, transcriptional, and translational levels. In the first stage of priming, constitutively, wingless-activated WJ-MSCs crossed the lineage boundary in favor of neuroectodermal lineage, identified by the loss of mesenchymal genes with concomitant expression of neuron-specific markers, like SOX1, PAX6, NTRK1, and NEUROD2. Neuronal-like cells formed in the second stage expressed many mature neuronal proteins like Map2, neurofilament, and Tuj1 and possessed axon hillock-like structures. In conclusion, the differentiation of a large number of neuronal-like cells from nontumorigenic and trophic factors secreting WJ-MSCs promises the development of a therapeutic strategy to treat neurodegenerative diseases.

Abstract
Mesenchymal stem cells (MSCs) are multipotent stromal cells that can be a useful source of cells for the treatment of many diseases, including neurologic diseases. The curative effect of MSCs relies mostly on cell’s capacity of migration, proliferation and differentiation. MicroRNAs (miRNAs) are small non-coding RNAs that play important roles on regulating various cell behaviors. Here, we report that miRNA-124 (miR124) and miRNA-21-5p (miR21-5p) display different regulatory roles on migration, proliferation and neuron differentiation of MSCs. MiR124 was shown greatly promoting MSCs migration and neuronal differentiation. MiR21-5p could significantly enhance the proliferation and neuronal differentiation ability of MSCs. MiR124 and miR21-5p synergistically promote differentiation of MSCs into neurons. Collectively, miR124 and miR21-5p can functionally regulate cell migration, proliferation and neuronal differentiation of MSCs. Therefore, miR124 and miR21-5p may be promising tools to improve transplantation efficiency for neural injury.

Abstract
BACKGROUNDS/AIMS Brain-derived neurotrophic factor (BDNF) plays a primary role in the maturation, proliferation, and differentiation of neuronal cells, can induce bone-marrow-derived mesenchymal stem cells (MSCs) to differentiate into nerve cells. This study aims to explore whether regulation of BDNF through microRNAs (miRNAs) in MSCs may further enhance the therapeutic effect on spinal cord injury (SCI). METHODS Bioinformatics analyses were done to predict miRNAs that target BDNF in MSCs. Dual-luciferase reporter gene assays were performed to verify the target relationship between microRNA and BDNF. We examined the mRNA and protein levels of BDNF in MSCs by RT-qPCR and Western blot, respectively. CCK 8 assay was chosen to assess cell viability. MSCs were transduced with miR-10a-5p-ASO, which were transplanted into rats that underwent SCI. The tissue integrity percentage, cavity volume, and Basso-Beattie-Bresnahan (BBB) scale were assessed. Neurofilament (NF) was detected using immunohistochemistry. Histological features of spinal cord tissues examined following HE staining. RESULTS MiR-10a-5p inhibited protein translation of BDNF, through binding to the 3'-UTR of the BDNF. MSCs transduced with MiR-10a-5p-ASO further increased the tissue integrity percentage, decreased cavity volume, and enhanced the recovery of BBB score in SCI model rats, compared to control MSCs. CONCLUSION Upregulation of BDNF by miR-10a-5p suppression in MSCs further improve the therapeutic potential of MSCs in treating SCI in rats.

Abstract
Neurogenesis is the basis of stem cell tissue engineering and regenerative medicine for central nervous system (CNS) disorders. We have established differentiation protocols to direct human periodontal ligament-derived stem cells (PDLSCs) into neuronal lineage, and we recently isolated the neural crest subpopulation from PDLSCs, which are pluripotent in nature. Here, we report the neural differentiation potential of these periodontal ligament-derived neural crest stem cells (NCSCs) as well as its microRNA (miRNA) regulatory mechanism and function in NCSC neural differentiation. NCSCs, treated with basic fibroblast growth factor and epidermal growth factor-based differentiation medium for 24 days, expressed neuronal and glial markers (βIII-tubulin, neurofilament, NeuN, neuron-specific enolase, GFAP, and S100) and exhibited glutamate-induced calcium responses. The global miRNA expression profiling identified 60 upregulated and 19 downregulated human miRNAs after neural differentiation, and the gene ontology analysis of the miRNA target genes confirmed the neuronal differentiation-related biological functions. In addition, overexpression of miR-132 in NCSCs promoted the expression of neuronal markers and downregulated ZEB2 protein expression. Our results suggested that the pluripotent NCSCs from human periodontal ligament can be directed into neural lineage, which demonstrate its potential in tissue engineering and regenerative medicine for CNS disorders.

Abstract
Central nervous system (CNS) injuries, such as stroke, traumatic brain injury (TBI) and spinal cord injury (SCI), are important causes of death and long-term disability worldwide. MicroRNA (miRNA), small non-coding RNA molecules that negatively regulate gene expression, can serve as diagnostic biomarkers and are emerging as novel therapeutic targets for CNS injuries. MiRNA-based therapeutics include miRNA mimics and inhibitors (antagomiRs) to respectively decrease and increase the expression of target genes. In this review, we summarize current miRNA-based therapeutic applications in stroke, TBI and SCI. Administration methods, time windows and dosage for effective delivery of miRNA-based drugs into CNS are discussed. The underlying mechanisms of miRNA-based therapeutics are reviewed including oxidative stress, inflammation, apoptosis, blood-brain barrier protection, angiogenesis and neurogenesis. Pharmacological agents that protect against CNS injuries by targeting specific miRNAs are presented along with the challenges and therapeutic potential of miRNA-based therapies.

Abstract
Spinal cord injury (SCI) represents one of the most complicated and heterogeneous pathological processes of central nervous system (CNS) impairments, which is still beyond functional regeneration. Transplantation of mesenchymal stem cells (MSCs) has been shown to promote the repair of the injured spinal cord tissues in animal models, and therefore, there is much interest in the clinical use of these cells. However, many questions which are essential to improve the therapy effects remain unanswered. For instance, the functional roles and related molecular regulatory mechanisms of MSCs in vivo are not yet completely determined. It is important for transplanted cells to migrate into the injured tissue, to survive and undergo neural differentiation, or to play neural protection roles by various mechanisms after SCI. In this review, we will focus on some of the recent knowledge about the biological behavior and function of MSCs in SCI. Meanwhile, we highlight the function of biomaterials to direct the behavior of MSCs based on our series of work on silk fibroin biomaterials and attempt to emphasize combinational strategies such as tissue engineering for functional improvement of SCI.

Abstract
Spinal cord injury (SCI) is a devastating condition that affects many people worldwide. Treatment focuses on controlling secondary injury cascade and improving regeneration. It has recently been suggested that both the secondary injury cascade and the regenerative process are heavily regulated by microRNAs (miRNAs). The measurement of specific biomarkers could improve our understanding of the disease processes, and thereby provide clinicians with the opportunity to guide treatment and predict clinical outcomes after SCI. A variety of miRNAs exhibit important roles in processes of inflammation, cell death, and regeneration. These miRNAs can be used as diagnostic tools for predicting outcome after SCI. In addition, miRNAs can be used in the treatment of SCI and its symptoms. Significant laboratory and clinical evidence exist to show that miRNAs could be used as robust diagnostic and therapeutic tools for the treatment of patients with SCI. Further clinical studies are warranted to clarify the importance of each subtype of miRNA in SCI management.

Abstract
MicroRNA (miRNA) functions in tissue regeneration and determines the fate of stem cells. Nanoparticle‐based miRNA delivery systems for therapeutic applications have been studied in clinical settings. However, gene delivery to stem cells is still a challenging issue. Lipid‐like nanoparticles produced using combinatorial approaches have recently been used for delivery of a variety of biologics. In this study, we investigated the ability of these lipids to deliver miRNA to human mesenchymal stem cells (hMSCs). First, small library screening of bioreducible lipids was performed using fluorophore‐conjugated miRNA to determine the optimal chemical structure for miRNA delivery to hMSCs. Next, miRNA‐9 (miR‐9), which promotes neuronal differentiation of stem cells, was delivered to hMSCs using the lipids identified from the library screening. Morphological changes of the cells and upregulation of neuronal marker genes were observed after the delivery of miR‐9. The synthetic bioreducible lipids are effective in facilitating miRNA delivery to hMSCs and promoting the neuronal differentiation.

Abstract
Human umbilical cord-derived mesenchymal stem cells (hUC-MSC) have been considered as promising candidates for cell-based regeneration medicine. However, the application was limited to its poor in vitro proliferation ability against the huge demand of cells. MicroRNA plays important roles in the regulation of cell proliferation, apoptosis, and differentiation. The objective of this study is to explore the roles of miRNAs in regulating the in vitro proliferation of hUC-MSC and unveil their possible mechanism. In this study, we found that miR-26b-3p was significantly upregulated during serial in vitro passage of hUC-MSC and was correlated with cellular senescence and cell cycle genes. The overexpression of miR-26b-3p greatly inhibited the proliferation of hUC-MSC in vitro, which is indicated by 5-ethynyl-2'-deoxyuridine (EdU) incorporation assay, cell cycle, and cell growth curve analyses. miR-26b-3p suppression partly rescued this phenotype by maintaining its proliferation ability in vitro. For mechanism studies, we predicted and validated that miR-26b-3p suppresses estrogen receptor 1 (ESR1) expression by directly binding to the coding sequence (CDS) region of its message RNA (mRNA), thus subsequently changing the expression of its downstream effector Cyclin D1. In conclusion, we found that miR-26b-3p played an important role in the regulation of hUC-MSC proliferation in vitro by targeting the ESR-CCND1 pathway.

Abstract
Ineffective therapeutic treatments and inadequate repair ability in the central nervous system are disturbing problems for several neurological diseases. Fortunately, the development of clinically applicable populations of stem cells has provided an avenue to overcome the failure of endogenous repair systems and substitute new cells into the damaged brain. However, there are still several existing obstacles to translating into clinical application. Here we review the stem-cell based therapies for Parkinson’s disease and discuss the potential advantages and drawbacks. We hope this review may provide suggestions for viable strategies to overcome the current technical and biological issues associated with the application of stem cells in Parkinson’s disease.
