Abstract
Resorption and atrophy of the alveolar bone, as two consequences of osteoporosis that remarkably complicate the orthodontic and prosthodontic treatments, contribute to the differentiated biological features and force-induced response of jaw bone marrow-derived mesenchymal stem cells (JBMSCs) in elderly patients. We isolated and cultured JBMSCs from adolescent and adult patients and then simulated the loading of orthodontic tension stress by constructing an in vitro three-dimensional (3D) stress loading model. The decline in osteogenic differentiation of aged JBMSCs was reversed by tensile stress stimulation. It is interesting to note that tension stimulation had a stronger effect on the osteogenic differentiation of elderly JBMSCs compared to the young ones, indicating a possible mechanism of aging rescue. High-throughput sequencing of microRNA (miRNAs) was subsequently performed before and after tension stimulation in all JBMSCs, followed by the comprehensive comparison of mechanically responsive miRNAs in the 3D strain microenvironment. The results suggested a significant reduction in the expression of miR-210-3p and miR-214-3p triggered by the 3D strain microenvironment in old-JBMSCs. Bioinformatic analysis indicated that both miRNAs participate in the regulation of critical pathways of aging and cellular senescence. Taken together, this study demonstrated that the 3D strain microenvironment efficiently rescued the cellular senescence of old-JBMSCs via modulating specific miRNAs, which provides a novel strategy for coordinating periodontal bone loss and regeneration of the elderly.

A mechanism linking ferroptosis and ferritinophagy in melatonin-related improvement of diabetic brain injury. iScience 2024; 27:109511. [PMID: 38571759 PMCID: PMC10987905 DOI: 10.1016/j.isci.2024.109511] [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: 09/12/2023] [Revised: 01/01/2024] [Accepted: 03/13/2024] [Indexed: 04/05/2024] Open
Abstract
Ferroptosis and ferritinophagy play critical roles in various disease contexts. Herein, we observed that ferroptosis and ferritinophagy were induced both in the brains of mice with diabetes mellitus (DM) and neuronal cells after high glucose (HG) treatment, as evidenced by decreases in GPX4, SLC7A11, and ferritin levels, but increases in NCOA4 levels. Interestingly, melatonin administration ameliorated neuronal damage by inhibiting ferroptosis and ferritinophagy both in vivo and in vitro. At the molecular level, we found that not only the ferroptosis inducer p53 but also the ferritinophagy mediator NCOA4 was the potential target of miR-214-3p, which was downregulated by DM status or HG insult, but was increased after melatonin treatment. However, the inhibitory effects of melatonin on ferroptosis and ferritinophagy were blocked by miR-214-3p downregulation. These findings suggest that melatonin is a potential drug for improving diabetic brain damage by inhibiting p53-mediated ferroptosis and NCOA4-mediated ferritinophagy through regulating miR-214-3p in neurons.

Abstract
Bone regeneration following trauma, tumor resection, infection, or congenital disease is challenging. Diabetes mellitus (DM) is a metabolic disease characterized by hyperglycemia. It can result in complications affecting multiple systems including the musculoskeletal system. The increased number of diabetes-related fractures poses a great challenge to clinical specialties, particularly orthopedics and dentistry. Various pathological factors underlying DM may directly impair the process of bone regeneration, leading to delayed or even non-union of fractures. This review summarizes the mechanisms by which DM hampers bone regeneration, including immune abnormalities, inflammation, reactive oxygen species (ROS) accumulation, vascular system damage, insulin/insulin-like growth factor (IGF) deficiency, hyperglycemia, and the production of advanced glycation end products (AGEs). Based on published data, it also summarizes bone repair strategies in diabetic conditions, which include immune regulation, inhibition of inflammation, reduction of oxidative stress, promotion of angiogenesis, restoration of stem cell mobilization, and promotion of osteogenic differentiation, in addition to the challenges and future prospects of such approaches.

Abstract
Diabetes mellitus (DM) and osteoporosis are two major health care problems worldwide. Emerging evidence suggests that DM poses a risk for osteoporosis and can contribute to the development of diabetes-induced osteoporosis (DOP). Interestingly, some epidemiological studies suggest that DOP may be at least partially distinct from those skeletal abnormalities associated with old age or postmenopausal osteoporosis. The increasing number of DM patients who also have DOP calls for a discussion of the pathogenesis of DOP and the investigation of drugs to treat DOP. Recently, non-coding RNAs (ncRNAs) have received more attention due to their significant role in cellular functions and bone formation. It is worth noting that ncRNAs have also been demonstrated to participate in the progression of DOP. Meanwhile, nano-delivery systems are considered a promising strategy to treat DOP because of their cellular targeting, sustained release, and controlled release characteristics. Additionally, the utilization of novel technologies such as the CRISPR system has expanded the scope of available options for treating DOP. Hence, this paper explores the functions and regulatory mechanisms of ncRNAs in DOP and highlights the advantages of employing nanoparticle-based drug delivery techniques to treat DOP. Finally, this paper also explores the potential of ncRNAs as diagnostic DOP biomarkers.

Abstract
Diabetes mellitus (DM) has been shown to be a clinical risk factor for bone diseases including osteoporosis and fragility. Bone metabolism is a complicated process that requires coordinated differentiation and proliferation of bone marrow mesenchymal stem cells (BMSCs). Owing to the regenerative properties, BMSCs have laid a robust foundation for their clinical application in various diseases. However, mounting evidence indicates that the osteogenic capability of BMSCs is impaired under high glucose conditions, which is responsible for diabetic bone diseases and greatly reduces the therapeutic efficiency of BMSCs. With the rapidly increasing incidence of DM, a better understanding of the impacts of hyperglycemia on BMSCs osteogenesis and the underlying mechanisms is needed. In this review, we aim to summarize the current knowledge of the osteogenesis of BMSCs in hyperglycemia, the underlying mechanisms, and the strategies to rescue the impaired BMSCs osteogenesis.

Abstract
Abnormally expressed miR-218-5p involves in alveolar bone defect. We intend to investigate whether miR-218-5p-modified bone marrow mesenchymal stem cells (BMSCs) mediates the healing effects of EphrinB2-EphB4 signals on the alveolar bone defect. Fifty germ-free rats (6-month-old) were
utilized in this study. The grouping was set up as follows: blank group, model group, miR-218-5p group, EphrinB2-EphB4 antagonist group, and positive control group (10 rats in each group). HE staining was employed to quantify bone resorption lacunae number. And the following indicators were
monitored: miR-218-5p expression, differentiation status of osteoblasts, concentrations of TNF-α/IL-10/ IL-8, and EphrinB2 and EphB4 expression. As shown in HE staining, massive infiltration of inflammatory cells was denoted at the alveolar bone defective sites in rats from model
group. However, infiltration of inflammatory cells in lesions was moderate in rats from EphrinB2-EphB4 antagonist group and positive control group, which was accompanied by formation of small bone islands. Furthermore, lesser infiltration of inflammatory cells was denoted at the alveolar bone
defective sites in rats from the miR-218-5p group, which also exhibited a larger number of newly formed bone trabeculae growing toward the center of lesions. On the 3rd day of culture, absorption lacunae were rare in the model group, while remaining undetectable in other groups. On the 7th
day of culture, bone resorption lacunae number in samples from model group was significantly higher in comparison with that in other groups. Meanwhile, it was reduced significantly in miR-218-5p group. However, it was increased in EphrinB2-EphB4 antagonist group and positive control group
(P <0.05). An elevation of the intracellular miR-218-5p level was denoted in the modified BMSCs in comparison with those unmodified BMSCs (P < 0.05). In comparison with blank group, other groups exhibited significantly elevated ALP levels, among which model group showed
highest level. However, decline of ALP levels was denoted in positive control group, EphrinB2-EphB4 antagonist group and miR-218-5p group, with lowest ALP level in miR-218-5p group (P <0.05). Except blank group, rats in other groups exhibited a significant elevation of TNF-α,
IL-10 and IL-8 in the serum, among which those in the model group displayed the most remarkable increase of these cytokines. Rats in miR-218-5p group, EphrinB2-EphB4 antagonist group and positive control group exhibited significantly reduced levels of IL-8, IL-10 and TNF-α in
the serum, with miR-218-5p group showing lowest levels (P < 0.05). In comparison with the blank group, other groups showed significantly enhanced protein expression of EphrinB2 and EphB4, among which the model group displayed the most remarkable enrichment of these proteins. In comparison
with the model group, samples from the miR-218-5p group, EphrinB2-EphB4 antagonist group and positive control group exhibited significantly weakened expression of EphrinB2 and EphB4, among which the miR-218-5p group displayed the most remarkable decrease of these proteins (P <0.05).
miR-218-5p-modified BMSCs can modulate the EphrinB2-EphB4 signal transduction pathway to produce two-way transmission, which included their inhibition of the osteoclast generation and their enhancement of the osteoclast differentiation. In this way, they aided in alleviating inflammatory response
in alveolar bone defective lesions, thereby accelerating the healing process of alveolar bone defect. The function of miR-218-5p-modified BMSCs is mainly achieved in the healing process of the alveolar bone defect.

Abstract
To study the effect of miR-153-3p on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) in a high glucose environment and its potential mechanism. The results showed that high glucose inhibited the osteogenic differentiation of BMSCs, and the expression of miR-153-3p increased during osteogenic differentiation. Further experiments found that in BMSCs induced by high glucose, overexpression of miR-153-3p inhibited the osteogenic differentiation of BMSCs, and the expressions of osteogenesis-related genes bone sialoprotein, Collagen I and alkaline phosphatase were down-regulated, while silencing of miR-153-3p alleviated the inhibition effect. The dual-luciferase reporter gene assay confirmed that the 3'-untranslated region (3'-UTR) of runt related transcription factor 2 (RUNX2) had a targeted binding site with miR-153-3p and a negative regulatory effect. Molecular studies further confirmed that miR-153-3p inhibited the osteogenic differentiation of BMSCs by targeting the 3'-UTR of RUNX2. In conclusion, our study found that as one key regulator of high glucose affecting the osteogenic differentiation of BMSCs, miR-153-3p may play a negative regulatory role by inhibiting the expression of RUNX2.

Abstract
Osteoporosis occurs frequently in women after menopause and old age, and it is very easy to cause osteoporotic fractures, resulting in disability and death. In osteoporosis patients, the potential of bone marrow mesenchymal stem cells (BMSCs) to differentiate into osteoblasts gradually is inhibited, leading to decreased new bone formation. In the current study, the potential effect of G-protein-coupled receptor 124 (GPR124) on the osteoblastic differentiation of BMSCs was determined. BMSCs were isolated and cultured in osteogenic media to induced osteogenic differentiation. Then, osteogenic differentiation was evaluated by Alizarin Red staining and ALP activity. The expression of osteogenic differentiation biomarkers, and Wnt/β-catenin signaling were determined by qRT-PCR and Western blotting. The results indicated that the expression of GPR124 was significantly increased during osteogenic differentiation of BMSCs. Moreover, GPR124 knockdown significantly inhibited osteoblastic differentiation and GPR124 overexpression promoted osteoblastic differentiation of BMSCs. GPR124 knockdown suppressed the activation of Wnt/β-catenin signaling pathway. What's more, the increased osteogenic differentiation induced by GPR124 overexpression was abolished by the inhibitor of Wnt/β-catenin pathway and Wnt7a knockdown. Taken together, GPR124 promotes osteogenic differentiation of BMSCs through the Wnt/β-catenin pathway and may serve as a potential target for enhancing osteogenesis of osteoporosis patients.

Abstract
PURPOSE OF REVIEW The incidence of diabetes is increasing worldwide. Diabetes mellitus is characterized by hyperglycemia, which in the long-term damages the function of many organs including the eyes, the vasculature, the nervous system, and the kidneys, thereby imposing an important cause of morbidity for affected individuals. More recently, increased bone fragility was also noted in patients with diabetes. While patients with type 1 diabetes mellitus (T1DM) have low bone mass and a 6-fold risk for hip fractures, patients with type 2 diabetes mellitus (T2DM) have an increased bone mass, yet still display a 2-fold elevated risk for hip fractures. Although the underlying mechanisms are just beginning to be unraveled, it is clear that diagnostic tools are lacking to identify patients at risk for fracture, especially in the case of T2DM, in which classical tools to diagnose osteoporosis such as dual X-ray absorptiometry have limitations. Thus, new biomarkers are urgently needed to help identify patients with diabetes who are at risk to fracture. RECENT FINDINGS Previously, microRNAs have received great attention not only for being involved in the pathogenesis of various chronic diseases, including osteoporosis, but also for their value as biomarkers. Here, we summarize the current knowledge on microRNAs and their role in diabetic bone disease and highlight recent studies on miRNAs as biomarkers to predict bone fragility in T1DM and T2DM. Finally, we discuss future directions and challenges for their use as prognostic markers.

Abstract
INTRODUCTION Diabetic osteoporosis (DOP) is a chronic diabetic complication, which is attributed to high glucose (HG)-induced dysfunction of bone marrow mesenchymal stem cells (BMSCs). Studies have revealed that microRNAs (miRNAs) play critical roles in osteogenic differentiation of BMSCs in DOP. Here, the role of miR-9-5p in DOP progression was explored. MATERIALS AND METHODS The rat model of DOP was established by intraperitoneal injection of streptozotocin (STZ). BMSCs were treated with high glucose (HG) to establish in vitro models. Gene expression in BMSCs and bone tissues of rats was tested by RT-qPCR. The degree of osteogenic differentiation of BMSCs was examined by Alizarin Red staining and ALP activity analysis. The protein levels of collagen-I (COL1), osteocalcin (OCN), osteopontin (OPN), runt-related transcription factor-2 (RUNX2), and DEAD-Box Helicase 17 (DDX17) in BMSCs were evaluated by western blotting. The interaction between miR-9-5p and DDX17 was identified by luciferase reporter assay. H&E staining was used to test morphological structure of femurs of rats with STZ treatment. RESULTS MiR-9-5p was overexpressed in HG-treated BMSCs, while DDX17 was downregulated. Functionally, miR-9-5p knockdown promoted BMSCs osteogenic differentiation under HG condition. Mechanically, miR-9-5p targeted DDX17. DDX17 knockdown reversed the effect of miR-9-5p silencing on osteogenic differentiation of HG-treated BMSCs. In in vivo studies, miR-9-5p downregulation ameliorated the DOP condition of rats and miR-9-5p expression was negatively correlated with DDX17 expression in bone tissues of rats with STZ treatment. CONCLUSION MiR-9-5p knockdown promotes HG-induced osteogenic differentiation BMSCs in vitro and mitigates the DOP condition of rats in vivo by targeting DDX17.

High glucose mediates apoptosis and osteogenesis of MSCs via downregulation of AKT-Sirt1-TWIST. Mol Biol Rep 2022; 49:2723-2733. [PMID: 35037196 DOI: 10.1007/s11033-021-07082-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Accepted: 12/10/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Mesenchymal stem cells have been widely used in the treatment of diabetes mellitus. However, hyperglycemia associated with DM promotes cell apoptosis and affects osteogenic differentiation of MSCs in varying degrees, leading to osteoporosis in DM patients. Therefore, in this paper, the effect of high glucose on apoptosis and osteogenesis of MSCs was investigated and underlying mechanism was further determined. METHODS AND RESULTS Intracellular ROS levels were determined using probe DCFH-DA. MMP was detected using JC-1 staining. Cell apoptosis was detected using Annexin V-FITC/PI and Flow Cytometer. The expression of genes and protein was detected by qRT-PCR and Western blot respectively. The results showed high glucose induced MSC apoptosis but promoted its osteogenesis. Western blot analysis revealed that high glucose downregulated AKT-Sirt1-TWIST pathway. Activation of Sirt1 via SRT1720 increased TWIST expression, alleviated MSC apoptosis and promoted osteogenesis of MSCs. TWIST knockdown studies demonstrated that inhibition of TWIST intensified high glucose-induced apoptosis but promoted osteogenesis differentiation of MSCs. TWIST is likely to be a new regulator for cross talk between Sirt1 and its downstream targets. CONCLUSION Our data demonstrates that high glucose induces MSC apoptosis and enhances osteogenesis differentiation via downregulation of AKT-Sirt1-TWIST.

Abstract
Chronic high glucose (HG) plays a crucial role in the pathogenesis of diabetes-induced osteoporosis by inhibiting the differentiation and proliferation of osteoblasts. This study aims to examine the role of E26 transformation-specific 1 (ETS1) in the inhibition of osteoblast differentiation and proliferation caused by chronic HG, as well as the underlying mechanism. Chronic HG treatment downregulated ETS1 expression and inhibited differentiation and proliferation of MC3T3-E1 cells. Downregulation of ETS1 expression inhibited the differentiation and proliferation of MC3T3-E1 cells under normal glucose conditions, and ETS1 overexpression attenuated the damage to cells exposed to chronic HG. In addition, ETS1 overexpression reversed the decrease in runt-related transcription factor 2 (Runx2) expression in MC3T3-E1 cells treated with chronic HG. Using chromatin immunoprecipitation (ChIP) and luciferase reporter assays, we confirmed that ETS1 directly bound to and increased the activity of the Runx2 promoter. In summary, our study suggested that ETS1 was involved in the inhibitory effect of chronic HG on osteogenic differentiation and proliferation and may be a potential therapeutic target for diabetes-induced osteoporosis.

Abstract
Fragility fracture is a common and serious complication of osteoporosis. Abnormal expression of long non-coding RNAs is closely related to orthopedic diseases and bone metabolism. In the study, the role of lncRNA PVT1 during fracture healing, and the potential mechanism were explained. In the present study, 80 cases with fragility fracture were collected, serum samples were also collected at 7, 14, 21 days after standardized fixation therapy. qRT-PCR was applied for the measurement of mRNA levels. hFOB1.19 cells were recruited for the cell experiments, and the cell viability and apoptosis were detected. Luciferase reporter gene assay was performed for target gene confirmation. It was found that the level of PVT1 increased gradually, while miR-497-5p showed a downward trend over time in both intra-articular and hand fracture patients, and the changes reached a significant level at 21 day after treatment. In vitro experiments demonstrated that PVT1 knockdown promoted cell proliferation and inhibited cell apoptosis in HFOB1.19 cells. LncRNA PVT1 acts as a competing endogenous RNA (ceRNA) of miR-497-5p, and the influence of PVT1 knockdown on HFOB1.19 cell proliferation and apoptosis was reversed by miR-497-5p inhibition. HMGA2 is the target gene of miR-497-5p. It was concluded that LncRNA PVT1 silencing may enhance fracture healing via mediating miR-497-5p/HMGA2 axis.

Abstract
Bone marrow mesenchymal stem cells (BMSCs) present reduced proliferation under high glucose condition. Liver kinase B1 (LKB1) can maintain the homeostasis of hematopoietic stem cells. However, whether LKB1 regulates BMSCs osteogenic/adipogenic differentiation under high glucose is unclear.
Rat BMSCs were isolated and separated into control group, high glucose group, and LKB1 group (BMSCs were transfected with pc-DNA 3.1-LKB1 plasmid under high glucose condition) followed by analysis of LKB1 expression by Real time PCR and Western blot, osteocalcin, type I collagen, RUNX2 and
OPN mRNA level by real-time PCR, FABP4 and PPARγ2 level by western blot. In high glucose group, LKB1 expression was significantly decreased, with reduced expression of osteocalcin, type I collagen, RUNX2 and OPN mRNA and elevated FABP4 and PPARγ2 level compared to control group
(P < 0.05). Transfection of LKB1 plasmid reduced LKB1 expression, upregulated osteocalcin, type I collagen, RUNX2 and OPN mRNA and downregulated FABP4 and PPARγ2. Compared with the high glucose group, there was a statistical difference (P <0.05). High glucose can
inhibit LKB1 expression and BMSCs osteogenic differentiation, and promote adipogenic differentiation. Upregulating LKB1 expression can promote BMSCs osteogenic differentiation.

Abstract
Patients with type 2 diabetes mellitus (T2DM) have a high risk of fracture and experience poor bone healing. In recent years, bone mesenchymal stem cells (BMSCs) and endothelial progenitor cells (EPCs) have become the most commonly used cells in cell therapy and tissue engineering. In this study, we found that high glucose levels had a negative effect on the differentiation of BMSCs and EPCs. Considering that EPCs-BMSCs sheets can provide endothelial cells and osteoblastic cells, we transplanted cell sheets into T2DM rats with bilateral skull defects. The outcomes of the in vivo study revealed that EPCs-BMSCs sheets promoted ossification, which was verified by micro-CT and immunohistochemistry (IHC) analyses. Furthermore, we detected the VEGF content in the culture supernatant using an enzyme-linked immunosorbent assay (ELISA). The results showed that the BMSCs co-cultured with EPCs presented a higher level of VEGF than other cells. To assess the differentiation and migration of BMSCs exposed to VEGF, ALP staining, scratch assay and qRT-PCR analysis were performed. In addition, we used immunofluorescence and western blotting analysis to further explore the related mechanisms. The results showed that cells cultured with VEGF had a stronger actin cytoskeleton and a greater amount of nuclear and total YAP than cells cultured without VEGF. Taken together, our results indicate that co-culture with EPCs could promote the osteogenesis of BMSCs partially via VEGF. Furthermore, YAP and F-actin play important roles in this process.
