Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by synovial inflammation, causing substantial disability and reducing life quality. While macrophages are widely appreciated as a master regulator in the inflammatory response of RA, the precise mechanisms underlying the regulation of proliferation and inflammation in RA-derived fibroblast-like synoviocytes (RA-FLS) remain elusive. Here, we provide extensive evidence to demonstrate that macrophage contributes to RA microenvironment remodeling by extracellular vesicles (sEVs) and downstream miR-100-5p/ mammalian target of rapamycin (mTOR) axis. RESULTS We showed that bone marrow derived macrophage (BMDM) derived-sEVs (BMDM-sEVs) from collagen-induced arthritis (CIA) mice (cBMDM-sEVs) exhibited a notable increase in abundance compared with BMDM-sEVs from normal mice (nBMDM-sEVs). cBMDM-sEVs induced significant RA-FLS proliferation and potent inflammatory responses. Mechanistically, decreased levels of miR-100-5p were detected in cBMDM-sEVs compared with nBMDM-sEVs. miR-100-5p overexpression ameliorated RA-FLS proliferation and inflammation by targeting the mTOR pathway. Partial attenuation of the inflammatory effects induced by cBMDM-sEVs on RA-FLS was achieved through the introduction of an overexpression of miR-100-5p. CONCLUSIONS Our work reveals the critical role of macrophages in exacerbating RA by facilitating the transfer of miR-100-5p-deficient sEVs to RA-FLS, and sheds light on novel disease mechanisms and provides potential therapeutic targets for RA interventions.

Abstract
The incidence of acute kidney injury (AKI) due to ischemia-reperfusion (IR) injury is increasing. There is no effective treatment for AKI, and because of this clinical challenge, AKI often progresses to chronic kidney disease, which is closely associated with poor patient outcomes and high mortality rates. Small extracellular vesicles from human umbilical cord mesenchymal stem cells (hUCMSC-sEVs) play increasingly vital roles in protecting tissue function from the effects of various harmful stimuli owing to their specific biological features. In this study, we found that miR-100-5p was enriched in hUCMSC-sEVs, and miR-100-5p targeted FKBP5 and inhibited HK-2 cell apoptosis by activating the AKT pathway. HK-2 cells that were exposed to IR injury were cocultured with hUCMSC-sEVs, leading to an increase in miR-100-5p levels, a decrease in FKBP5 levels, and an increase in AKT phosphorylation at Ser 473 (AKT-473 phosphorylation). Notably, these effects were significantly reversed by transfecting hUCMSCs with an miR-100-5p inhibitor. Moreover, miR-100-5p targeted FKBP5, as confirmed by a dual luciferase reporter assay. In vivo, intravenous infusion of hUCMSC-sEVs into mice suffering from IR injury resulted in significant apoptosis inhibition, functional maintenance and renal histological protection, which in turn decreased FKBP5 expression levels. Overall, this study revealed an effect of hUCMSC-sEVs on inhibiting apoptosis; hUCMSC-sEVs reduced renal IR injury by delivering miR-100-5p to HK-2 cells, targeting FKBP5 and thereby promoting AKT-473 phosphorylation to activate the AKT pathway. This study provides novel insights into the role of hUCMSC-sEVs in the treatment of AKI.

Abstract
OBJECTIVES MicroRNA (miRNA) is a kind of highly conserved single-stranded small endogenous non-coding RNA associated with multiple diseases, particularly cancer. The miRNAs expression profile in multiple myeloma (MM) has been barely elucidated. METHODS The miRNAs expression profiles in bone marrow plasma cells of 5 MM individuals and 5 iron-deficiency anemia volunteers were analyzed using RNA-sequencing. Quantitative polymerase chain reaction (QPCR) was performed to validate the expression of selected miR-100-5p. The biological function of selected miRNA was predicated by bioinformatics analysis. Finally, the function of miR-100-5p and its target on MM cells were evaluated. RESULTS MiRNA-sequencing showed that miR-100-5p was obviously upregulated in MM patients, which was further validated in an expanded cohort. Receiver operating characteristic curve analysis characterized miR-100-5p as a valuable biomarker of MM. Bioinformatics analysis predicted that miR-100-5p is targeted to CLDN11, ICMT, MTMR3, RASGRP3, and SMARCA5, and their low expression are associated with poor prognosis of MM patients. Kyoto encyclopedia of genes and genomes analysis suggested that the major interacting proteins of these five targets are mainly enriched in inositol phosphate metabolism and phosphatidylinositol signaling system pathway. In vitro study showed that miR-100-5p inhibition promoted the expression of these targets, especially MTMR3. In addition, miR-100-5p inhibition declined living number and metastasis, whereas promoted apoptosis of RPMI 8226 and U266 MM cells. The function of miR-100-5p inhibition was weakened by MTMR3 inhibition. CONCLUSION These results indicates that miR-100-5p is a promising biomarker for MM, and that it may involve in the pathogenesis of MM by targeting MTMR3.

Abstract
BACKGROUND The pathogenesis of Parkinson's disease (PD) has not been fully elucidated, and there are no effective disease-modifying drugs for the treatment of PD. Mesenchymal stem cells have been used to treat several diseases, but are not readily available. METHODS Here, we used phenotypically uniform trophoblast stage-derived mesenchymal stem cells (T-MSCs) from embryonic stem cells, which are capable of stable production, and their exosomes (T-MSCs-Exo) to explore the molecular mechanisms involved in dopaminergic (DA) neuron protection in PD models using experimental assays (e.g., western blotting, immunofluorescence and immunohistochemistry staining). RESULTS We assessed the levels of DA neuron injury and oxidative stress in MPTP-induced PD mice and MPP+-induced MN9D cells after treating them with T-MSCs or T-MSCs-Exo. Furthermore, T-MSCs-Exo miRNA sequencing analysis revealed that miR-100-5p-enriched T-MSCs-Exo directly targeted the 3' UTR of NOX4, which could protect against the loss of DA neurons, maintain nigro-striatal system function, ameliorate motor deficits, and reduce oxidative stress via the Nox4-ROS-Nrf2 axis in PD models. CONCLUSIONS The study suggests that miR-100-5p-enriched T-MSCs-Exo may be a promising biological agent for the treatment of PD. Schematic summary of the mechanism underlying the neuroprotective actions of T-MSCs-Exo in PD. T-MSCs Exo may inhibit the expression level of the target gene NOX4 by delivering miR-100-5p, thereby reducing ROS production and alleviating oxidative stress via the Nox4-ROS-Nrf2 axis, thus improving DA neuron damage in PD.

Abstract
BACKGROUND Human induced pluripotent stem cell-derived endothelial cells (hiPSC-ECs) exhibit the potential to repair the injured heart after myocardial infarction (MI) by promoting neovascularization and cardiomyocyte survival. However, because of the low cellular retention and poor engraftment efficacy, cell therapy of MI is partly mediated by exosomes secreted from the transplanted cells. In this study, we investigated whether exosomes secreted from hiPSC-ECs could become a promising acellular approach to repair the infarcted heart after MI and elucidated the underlying protective mechanism. METHODS The hiPSC-ECs were differentiated, and exosomes were isolated in vitro. Then, hiPSC-EC exosomes were delivered by intramyocardial injection in a murine MI model in vivo. Echocardiography, combined with hemodynamic measurement, histological examination, Ca2+ transient and cell shortening assessment, and Western blot, was used to determine the protective effects of hiPSC-EC exosomes on the infarcted heart. Furthermore, microRNA sequencing, luciferase activity assay, and microRNA gain-loss function experiments were performed to investigate the enriched microRNA and its role in exosome-mediated effects. RESULTS In vitro, the hiPSC-EC exosomes enhanced intracellular Ca2+ transients, increased ATP content, and improved cell survival to protect cardiomyocytes from oxygen-glucose deprivation injury. Congruously, hiPSC-EC exosome administration in vivo improved the myocardial contractile function and attenuated the harmful left ventricular remodeling after MI without increasing the frequency of arrhythmias. Mechanistically, the hiPSC-EC exosomes notably rescued the protein expression and function of the sarcoplasmic reticulum Ca2+ ATPase 2a (SERCA-2a) and ryanodine receptor 2 (RyR-2) to maintain intracellular Ca2+ homeostasis and increase cardiomyocyte contraction after MI. The microRNA sequencing showed that miR-100-5p was the most abundant microRNA in exosomes. miR-100-5p could target protein phosphatase 1β (PP-1β) to enhance phospholamban (PLB) phosphorylation at Ser16 and subsequent SERCA activity, which contributes to the hiPSC-EC exosome-exerted cytoprotective effects on maintaining intracellular Ca2+ homeostasis and promoting cardiomyocyte survival. CONCLUSION The hiPSC-EC exosomes maintain cardiomyocyte Ca2+ homeostasis to improve myocardial recovery after MI, which may provide an acellular therapeutic option for myocardial injury.

Abstract
In recent years, the association between microRNAs (miRNAs) and autophagy in cerebral infarction (CI) has attracted increasingly more attention. The mammalian target of the rapamycin (mTOR) pathway is a key protein regulating the autophagy response. miR-100-5p can bind to the mTOR protein, but its role in CI remains unclear yet. This experiment aims to clarify the role of miR-100-5p in CI. Bioinformatics analysis was performed to screen differentiated expressed functional genes between CI tissue and normal tissue specimens. In vivo experiments: the mouse model of CI was established by middle cerebral artery occlusion (MCAO) methods, After being treated with miR-100-5p-overexpressing lentivirus, the amount of terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling (TUNEL)-positive fluorescence and the fluorescent expression level of mTOR protein were significantly inhibited in the CI region. Western blotting analysis showed that miR-100-5p inhibited the protein expression level of phosphorylated mTOR and total mTOR and enhanced the expression of autophagy-related proteins Beclin, microtubule-associated protein light chain 3II (LC-3II), and autophagy-related gene 7 (ATG-7). For in vitro experiment, after the BV-2 cells were successfully infected with the control lentivirus and miR-100-5p-overexpression lentivirus, they were stimulated with 1% hypoxia and low-glucose medium in a tri-gas incubator for 24 h. It was found that miR-100-5p could significantly lower the protein expression level of phosphorylated mTOR and total mTOR, and increase the expression of the Beclin, LC-3II, ATG-7 autophagy related proteins. miR-100-5p promotes the autophagy response through binding to mTOR protein, thereby inhibiting apoptosis and delaying the progression of CI.

Abstract
MicroRNAs (miRNAs) are endogenous small non-coding RNAs that play crucial regulatory roles in many biological processes, including the growth and development of skeletal muscle. miRNA-100-5p is often associated with tumor cell proliferation and migration. This study aimed to uncover the regulatory mechanism of miRNA-100-5p in myogenesis. In our study, we found that the miRNA-100-5p expression level was significantly higher in muscle tissue than in other tissues in pigs. Functionally, this study shows that miR-100-5p overexpression significantly promotes the proliferation and inhibits the differentiation of C2C12 myoblasts, whereas miR-100-5p inhibition results in the opposite effects. Bioinformatic analysis predicted that Trib2 has potential binding sites for miR-100-5p at the 3'UTR region. A dual-luciferase assay, qRT-qPCR, and Western blot confirmed that Trib2 is a target gene of miR-100-5p. We further explored the function of Trib2 in myogenesis and found that Trib2 knockdown markedly facilitated proliferation but suppressed the differentiation of C2C12 myoblasts, which is contrary to the effects of miR-100-5p. In addition, co-transfection experiments demonstrated that Trib2 knockdown could attenuate the effects of miR-100-5p inhibition on C2C12 myoblasts differentiation. In terms of the molecular mechanism, miR-100-5p suppressed C2C12 myoblasts differentiation by inactivating the mTOR/S6K signaling pathway. Taken together, our study results indicate that miR-100-5p regulates skeletal muscle myogenesis through the Trib2/mTOR/S6K signaling pathway.

Abstract
BACKGROUND Esophageal squamous cell carcinoma (ESCC), an aggressive gastrointestinal tumor, often has high early lymphatic metastatic potential. Cancer-associated fibroblasts (CAFs) are primary components in tumor microenvironment (TME), and the impact of CAFs and its derived exosomes on lymphangiogenesis remains elusive. MATERIALS AND METHODS CAFs and the microlymphatic vessel density (MLVD) in ESCC was examined. Exosomes were extracted from primary normal fibroblast (NFs) and CAFs. Subsequently, tumor-associated lymphatic endothelial cells (TLECs) were treated with these exosomes, and the effect on their biological behavior was examined. miR-100-5p was selected as the target miRNA, and its effect on TLECs was examined. The target of miR-100-5p was predicted and confirmed. Subsequently, IGF1R, PI3K, AKT, and p-AKT expression in TLECs and tumors treated with exosomes and miR-100-5p were examined. RESULTS A large number of CAFs and microlymphatic vessels were present in ESCC, leading to a poor prognosis. CAF-derived exosomes promoted proliferation, migration, invasion, and tube formation in TLECs. Further, they also enhanced lymphangiogenesis in ESCC xenografts. miR-100-5p levels were significantly lower in CAF-derived exosomes than in NF-derived exosomes. miR-100-5p inhibited proliferation, migration, invasion, and tube formation in TLECs. Further, miR-100-5p inhibited lymphangiogenesis in ESCC xenografts. Mechanistic studies revealed that this inhibition was mediated by the miR-100-5p-induced inhibition of IGF1R/PI3K/AKT axis. CONCLUSION Taken together, our study demonstrates that CAF-derived exosomes with decreased miR-100-5p levels exhibit pro-lymphangiogenesis capacity, suggesting a possibility of targeting IGF1R/PI3K/AKT axis as a strategy to inhibit lymphatic metastasis in ESCC.

Abstract
Mycobacterium tuberculosis (M. tb) is the causative agent of tuberculosis (TB) that leads to millions of deaths each year. Extensive evidence has explored the involvement of microRNAs (miRNAs) in M. tb infection. Limitedly, the concrete function of microRNA-100-5p (miR-100-5p) in M. tb remains unexplored and largely elusive. In this study, using Bacillus Calmette-Guérin (BCG) as the model strain, we validated that miR-100-5p was significantly decreased in BCG-infected THP-1 cells. miR-100-5p inhibition effectively facilitated the apoptosis of infected THP-1 cells and reduced BCG survival by regulating the phosphatidylinositol 3-kinase/AKT pathway. Further, SMARCA5 was the target of miR-100-5p and reduced after miR-100-5p overexpression. Since BCG infection down-regulated miR-100-5p in THP-1 cells, the SMARCA5 expression was up-regulated, which in turn increased apoptosis through caspase-3 and Bcl-2 and, thereby, reducing BCG intracellular survival. Collectively, the study uncovered a new molecular mechanism of macrophage to suppress mycobacterial infection through miR-100-5p and SMARCA5 pathway.

Abstract
Osteoporosis is a disorder characterized by reduced bone mass, disruption of bone microarchitecture, and a propensity to fracture. The osteogenic differentiation of human bone mesenchymal stromal cells (hBMSCs) exerts a critical effect on preventing bone loss during osteoporosis. Herein, the study recognized miR-100-5p as a deregulated miRNA during osteoporosis (upregulated) and BMSC osteogenic differentiation (downregulated). miR-100-5p was upregulated in osteoporosis patients-isolated BMSCs compared to non-osteoporosis trauma patients-isolated BMSCs. hBMSCs, overexpression inhibited hBMSC proliferation and osteogenic differentiation, whereas miR-100-5p inhibition exerted opposite effects. TMEM135 was downregulated in osteoporosis and upregulated in differentiated osteoblasts, as well as downregulated upon the overexpression of miR-100-5p. MiR-100-5p directly targeted and inhibited TMEM135. In hBMSCs, TMEM135 silencing also inhibited hBMSC osteogenic differentiation. When co-transfected to hBMSCs, antagomir-100-5p promoted, whereas TMEM135 silencing inhibited hBMSC osteogenic differentiation; TMEM135 knockdown dramatically attenuated the effects of miR-100-5p inhibition. Taken together, miR-100-5p forms a regulatory axis with TMEM135 by direct binding. The miR-100-5p/TMEM135 axis modulates hBMSC differentiation into osteoblast. Considering the critical effect of BMSC osteogenesis on osteoporosis, this axis might play a role in osteoporosis, and further in vivo and clinical investigations are required.

Abstract
Background Mesenchymal stem cell-derived small extracellular vesicles (MSC-sEVs) have been increasingly proved as promising immunomodulators against some autoimmune disorders. However, the possible effect and the underlying mechanism of MSC-sEVs in autoimmune dry eye have been rarely studied. Methods Small extracellular vesicles from human umbilical cord mesenchymal stem cells (hUC-MSC-sEVs) were subconjunctivally injected to rabbit dry eye model, and their preventive or therapeutical effects were assessed by recording the clinical and histological scores. Quantitative real-time PCR (Q-PCR), western blot and flow cytometry were performed to evaluate the immunomodulatory effects of hUC-MSC-sEVs on macrophages and T regulatory cells (Tregs) both in vivo and in vitro, and the in vitro T cell proliferation was detected by Bromodeoxyuridine (BrdU) assay. In addition, high expression of miR-100-5p in hUC-MSC-sEVs was identified by Q-PCR, and the functional role of sEVs-miR-100-5p on macrophages was explored by a series of co-culture experiments using sEVs derived from hUC-MSCs transfected with miR-100-5p inhibitor. Results We firstly demonstrated that hUC-MSC-sEVs had the preventive and therapeutical effects on rabbit autoimmune dacryoadenitis, an animal model of Sjögren’s syndrome (SS) dry eye. Further investigation revealed that hUC-MSC-sEVs administration effectively elicited macrophages into an anti-inflammatory M2 phenotype and elevated the proportion of Tregs both in vivo and in vitro, which contributed to reduced inflammation and improved tissue damage. Importantly, hUC-MSC-sEVs-educated macrophages with M2-like phenotype exhibited strong capacity to inhibit CD4+ T cell proliferation and promote Treg generation in vitro. Mechanistically, miR-100-5p was highly enriched in hUC-MSC-sEVs, and knockdown of miR-100-5p in hUC-MSC-sEVs partially blunted the promotion of hUC-MSC-sEVs on M2 macrophage polarization and even attenuated the effect of hUC-MSC-sEVs-educated macrophages on T cell suppression and Treg expansion. Conclusion Our data indicated that hUC-MSC-sEVs alleviated autoimmune dacryoadenitis by promoting M2 macrophage polarization and Treg generation possibly through shuttling miR-100-5p. This study sheds new light on the application of MSC-sEVs as a promising therapeutic method for SS dry eye.

Abstract
Papillary thyroid cancer (PTC) is the most prevalent type of TC worldwide; however, its pathological process remains unclear at the molecular level. In the current study, we analyzed the microarray data of PTC tissues and non-neoplastic thyroid tissues, and confirmed miR-100-5p as a downregulated miRNA in PTC. Via bioinformatic approach, western blotting, and TOP/FOP-flash assay, miR-100-5p was observed to be involved in the inactivation of Wnt/β-catenin signaling in TPC-1 and KTC-1. Frizzled Class Receptor 8 (FZD8), the coupled receptor for canonical Wnt/β-catenin signaling, was verified to be targeted and inhibited by miR-100-5p in TPC-1 and KTC-1. In the function assay, miR-100-5p mimic repressed PTC cell proliferation and induced cell apoptosis of TPC-1 and KTC-1; meanwhile, transfection of full-length FZD8 attenuated the effect of miR-100-5p mimic. Moreover, in the collected samples, miR-100-5p was lowly expressed in PTC tissues compared with normal tissues, especially in those of advanced stage (Stage III/IV vs Stage I/II), while FZD8 was highly expressed in PTC tissues, which in PTC tissues was inversely correlated to miR-100-5p. Thus, we suggest that overexpression of miR-100-5p inhibits the development of PTC by targeting FZD8.

Abstract
The growth of endometrial stromal cells (ESCs) at implantation sites may be a potential factor affecting the success rate of embryo implantation. Incremental proofs demonstrated that ncRNAs (e.g. miRNAs, lncRNAs and circRNAs) were involved in various biological procedures, including proliferation and apoptosis. In this study, the role of miR‐100‐5p on proliferation and apoptosis of goat ESCs in vitro and embryo implantation in vivo was determined. The mRNA expression of miR‐100‐5p was significantly inhibited in the receptive phase (RE) rather than in the pre‐receptive phase (PE). Overexpression of miR‐100‐5p suppressed ESCs proliferation and induced apoptosis. The molecular target of MiR‐100‐5p, HOXA1, was confirmed by 3′‐UTR assays. Meanwhile, the product of HOXA1 mRNA RT‐PCR increased in the RE more than that in the PE. The HOXA1‐siRNA exerted significant negative effects on growth arrest. Instead, incubation of ESCs with miR‐100‐5p inhibitor or overexpressed HOXA1 promoted the cell proliferation. In addition, Circ‐9110 which acted as a sponge for miR‐100‐5p reversed the relevant biological effects of miR‐100‐5p. The intrinsic apoptosis pathway was suppressed in ESCs, revealing a crosstalk between Circ‐9110/miR‐100‐5p/HOXA1 axis, PI3K/AKT/mTOR, and ERK1/2 pathways. To further evaluate the progress in study on embryo implantation regulating mechanism of miR‐100‐5p in vivo, the pinopodes of two phases were observed and analysed, suggesting that, as similar as in situ, miR‐100‐5p was involved in significantly regulating embryo implantation in vivo. Mechanistically, miR‐100‐5p performed its embryo implantation function through regulation of PI3K/AKT/mTOR and ERK1/2 pathways by targeting Circ‐9110/miR‐100‐5p/HOXA1 axis in vivo.

Abstract
Background Anti-angiogenic therapy has been shown to be a promising strategy for anti-tumor treatment. Increasing evidence indicates that tumor angiogenesis is affected by exosomes that are secreted by mesenchymal stem cells (MSCs), but whether exosomes derived from MSCs suppress or promote angiogenesis remain paradoxical. The purpose of this study focused on understanding the potential role of exosomes derived from stem cells of human deciduous exfoliated teeth (SHED-Exos) in regulating angiogenesis and the underlying molecular mechanism. Methods Exosomes were isolated from supernatants of SHED cells using an exosome purification kit and were characterized by transmission electron microscopy, nanoparticle tracking analysis and western blot analysis. Cell Counting Kit-8, flow cytometric assays, western blots, wound healing and transwell migration assays were performed to characterize the roles of SHED-Exos on cell proliferation, apoptosis and migration of human umbilical vein endothelial cells (HUVECs). The anti-angiogenic activity of SHED-Exos was assessed via a tube formation assay of endothelial cells and angiogenesis-related factors were analyzed by western blotting. In vivo, we used the chick chorioallantoic membrane (CAM) assay and an oral squamous cell carcinoma (OSCC) xenograft transplantation model with nude mice that received multi-point injections at three-day intervals to evaluate the effects on angiogenesis. Furthermore, the sequencing of microRNAs (miRNAs) in SHED-Exos was performed to investigate the underlying anti-angiogenic mechanism. Results The results showed that SHED-Exos inhibit cell proliferation and migration and induce apoptosis in HUVECs. SHED-Exos suppress the tube-like structure formation of HUVECs in vitro. SHED-Exos downregulate several angiogenesis-related factors, including VEGFA, MMP-9 and ANGPT1. In vivo, the chick CAM assay verified that treatment with SHED-Exos inhibits micro-vascular formation, and importantly, significantly reduces the micro-vascular formation of tumors generated from xenografted OSCC cells, which was associated with the inhibition of tumor growth in vivo. Mechanistically, our data suggested that SHED-Exos are enriched with miR-100-5p and miR-1246 and are transferred to endothelial cells, which results in decreased tube formation via the down-regulation of VEGFA expression. Conclusions These results demonstrate that SHED-Exos inhibit angiogenesis in vitro and in vivo, which suggests that SHED-Exos could potentially serve as a novel and effective therapeutic approach for anti-angiogenic treatment.

Abstract
The end result of a variety of cardiovascular diseases is heart failure. Heart failure patients’ morbidity and mortality rates are increasing year after year. Extracellular vesicles (EVs) derived from human umbilical cord mesenchymal stem cells (HucMSC-EVs) have recently been discovered to be an alternative treatment for heart failure, according to recent research. In this study, we aimed to explore the underlying mechanisms in which HucMSC-EVs inhibited doxorubicin (DOX)-induced heart failure in AC16 cells. An miR-100-5p inhibitor and an miR-100-5p mimic were used to transfect HucMSCs using Lipofectamine 2000. HucMSC-EVs were isolated and purified using the ultracentrifugation method. AC16 cells were treated with DOX combined with HucMSC-EVs or an EV miR-100-5-p inhibitor or EV miR-100-5-p mimic. ROS levels were measured by a flow cytometer. The levels of LDH, SOD, and MDA were measured by biochemical methods. Apoptotic cells were assessed by a flow cytometer. Cleaved-caspase-3 and NOX4 protein expression were determined by Western blot. The experiment results showed that HucMSC-EVs inhibited DOX-induced increased levels of ROS, LDH, and MDA, and decreased levels of SOD which were reversed by an EV miR-100-5-p inhibitor, while EV miR-100-5-p mimic had a similar effect to HucMSC-EVs. At the same time, HucMSC-EV-inhibited DOX induced the increases of apoptotic cells as well as NOX4 and cleaved-caspase-3 protein expression, which were reversed by an EV miR-100-5-p inhibitor. Furthermore, the NOX4 expression was negatively regulated by miR-100-5p. Overexpression of NOX4 abolished the effects in which HucMSC-EVs inhibited DOX-induced ROS, oxidative stress, and apoptosis increases. In conclusion, these results indicate that HucMSC-EVs inhibit DOX-induced heart failure through the miR-100-5p/NOX4 pathway.

Abstract
Autophagy has been proved to play a vital role in cardiac hypertrophy. The present study was designed to investigate the relationship between miR-100-5p and autophagy in the development of cardiac hypertrophy. Here, miR-100-5p expression was detected in abdominal aortic coarctation (AAC)-induced cardiac hypertrophy rats and Angiotensin II (Ang II)-stimulated cardiomyocytes. In vitro and in vivo experiments were performed to explore the function of miR-100-5p on autophagy and cardiac hypertrophy. We also investigated the mechanism of miR-100-5p on autophagy with dual-luciferase reporter assays, RNA immunoprecipitation (RIP), quantitative real-time PCR (qRT-PCR), western blot, immunofluorescence, and transmission electron microscopy (TEM). The results showed that miR-100-5p was highly expressed in hypertrophic hearts and Ang II-induced cardiomyocytes. Overexpression of miR-100-5p promoted the expression of cardiac hypertrophy markers ANP, BNP and β-MHC and cell surface area, while those were suppressed by miR-100-5p inhibitor. Knockdown of miR-100-5p by antagomiR significantly improves cardiac function and attenuate cardiac hypertrophy in vivo. Mechanistic investigation has found that miR-100-5p promote autophagy by targeting mTOR. Inhibition of autophagy by 3-methyladenine (3-MA) or mTOR overexpression could reverse the function of miR-100-5p in cardiac hypertrophy. These results elucidate that miR-100-5p promoted the pathogenesis of cardiac hypertrophy through autophagy activation by targeting mTOR.

Abstract
Exosomes derived from human umbilical cord mesenchymal stem cells (hUCMSC-Ex) play important roles in immune and inflammation diseases. However, the role of hUCMSC-Ex in atherosclerosis has not been elucidated. In this study, the isolated exosomes were identified by transmission electron microscopy and nanoparticle tracking analysis. Exosome marker protein levels were increased in the hUCMSC-Ex compared with those in hUCMSC suspension, indicating that exosomes were successfully isolated from hUCMSCs. Furthermore, eosinophils were treated with oxidized low-density lipoprotein (ox-LDL) to construct inflammation model and then incubated with hUCMSC-Ex derived from hUCMSCs which were transfected with miR-100-5p mimic or miR-100-5p inhibitor. We found that hUCMSC-Ex increased miR-100-5p expression, inhibited cell migration, promoted cell apoptosis, and reduced inflammatory cytokine levels in ox-LDL-treated eosinophils, and miR-100-5p overexpression in hUCMSCs enhanced these effects, while miR-100-5p inhibition reversed these effects. Moreover, frizzled 5 (FZD5) was a target gene of miR-100-5p. FZD5 overexpression reversed the inhibitory effects of hUCMSC-Ex-miR-100-5p on cell progression and inflammation in eosinophils. Additionally, hUCMSC-Ex-miR-100-5p decreased the expression of cyclin D1 and β-catenin proteins. Wnt/β-catenin pathway activator BML-284 effectively reversed the effects of hUCMSC-Ex-miR-100-5p on cell progression and inflammation in eosinophils. ApoE-/- mice were fed with high-fat diet to construct an atherosclerosis mice model, and hUCMSC-Ex was injected into mice. hUCMSC-Ex reduced atherosclerotic plaque area and inflammation response in atherosclerosis mice. This study demonstrates that hUCMSC-Ex-miR-100-5p inhibits cell progression and inflammatory response in eosinophils via the FZD5/Wnt/β-catenin pathway, thereby alleviating atherosclerosis progression.

Abstract
Background Nontraumatic osteonecrosis of the femoral head (NONFH) is a common, progressive, and refractory orthopaedic disease. Decreased osteogenesis and angiogenesis are considered the main factors in the pathogenesis of NONFH. We aimed to figure out whether exosomes and exosomal miRNA from necrotic bone tissues of patients with NONFH are involved in the pathogenesis of NONFH and reveal the underlying mechanisms. Methods RT-PCR and western blotting (WB) were used to detect the expression of osteogenic, adipogenic, and angiogenic markers. ALP staining and Alizarin Red S (ARS) staining were used to evaluate osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (hBMSCs). Oil Red O staining was performed to assess the adipocyte deposition. A tube formation assay was used to study angiogenesis of human umbilical vascular endothelial cells (HUVECs). H&E staining and immunohistochemistry (IHC) staining were used to detect the effect of the NONFH exosomes in vivo. MicroRNA sequencing was conducted to identify potential regulators in the NONFH exosomes. The target relationship between miR-100-5p and BMPR2 was predicted and confirmed by a dual luciferase reporter assay and WB. Results The NONFH exosomes reduced the osteogenic differentiation of hBMSCs and angiogenesis of HUVECs. In addition, the injection of the NONFH exosomes caused thinning and disruption of bone trabeculae in the femoral heads of rats. MiR-100-5p expression was upregulated in the NONFH exosomes and inhibited the osteogenesis of hBMSCs and angiogenesis of HUVECs by targeting BMPR2 and suppressing the BMPR2/SMAD1/5/9 signalling pathway. Silencing miR-100-5p expression rescued the reduction in osteogenesis and angiogenesis caused by the NONFH exosomes by activating the BMPR2/SMAD1/5/9 signalling pathway. Conclusion The NONFH exosomal miR-100-5p can lead to NONFH-like damage by targeting BMPR2 and suppressing the BMPR2/SMAD1/5/9 signalling pathway, which may be involved in the pathophysiological mechanisms of nontraumatic osteonecrosis of the femoral head (NONFH).

Abstract
MicroRNAs (miRNAs) are important regulators of many cellular processes, and the dysregulation of miRNAs is associated with various diseases. MiR-100-5p is revealed to be downregulated in gestational hypertension, while its underlying regulatory mechanism remains unclear. The pathological condition of gestational hypertension was mimicked by the hypoxia and reoxygenation (H/R) treatment to human placental microvascular endothelial cells (HPMECs). RT-qPCR and western blotting were conducted to detect the mRNA and protein expression of RNAs. HPMEC viability was assessed by CCK-8 assay. HPMEC angiogenesis was examined using tube formation assay. The concentrations of ANG-1 and ANG-2 in HPMECs were detected by ELISA. The binding relationship between miR-100-5p and homeodomain interacting protein kinase 2 (HIPK2) was investigated using luciferase reporter assay. MiR-100-5p was downregulated in HPMECs after H/R treatment. MiR-100-5p overexpression reversed the H/R-induced decrease in viability, angiogenesis of HPMECs. HIPK2 was targeted by miR-100-5p in HPMECs, and miR-100-5p negatively modulated HIPK2 expression at the mRNA and protein levels. MiR-100-5p activated the PI3K/AKT pathway by downregulating HIPK2. Rescue assays demonstrated that miR-100-5p promoted the viability and angiogenesis of H/R treated HPMECs by targeting HIPK2 to activate the PI3K/AKT pathway. MiR-100-5p overexpression inhibits the dysfunction of HPMECs under hypoxia and reoxygenation by downregulating HIPK2 to activate the PI3K/AKT pathway.

Abstract
Cyclic strain-induced chondrocyte damage is actively involved in the pathogenesis of osteoarthritis and arthritis. MicroRNAs (miRNAs) carried by exosomes have been implicated in various diseases. However, the role of miR-100-5p in cyclic strain-induced chondrocyte damage remains to be elucidated. miR-100-5p and NADPH oxidase 4 (NOX4) were silenced or overexpressed in human primary articular chondrocytes. PKH-67 Dye was used to trace exosome endocytosis. Reactive oxygen species (ROS) production was monitored using DCFH-DA. Cell apoptosis was measured using a flow cytometer. Quantitative RT-PCR and Western blots were used to evaluate gene expression. Cyclic strain promoted ROS production and apoptosis in primary articular chondrocytes in a time-dependent manner. HucMSCs-derived exosomal miR-100-5p inhibited cyclic strain-induced ROS production and apoptosis in primary articular chondrocytes. miR-100-5p directly targeted NOX4. Overexpressing NOX4 attenuated hucMSCs-derived exosomes-mediated protective effects in primary articular chondrocytes. Cyclic strain promotes ROS production and apoptosis in primary articular chondrocytes, which was abolished by hucMSCs-derived exosomal miR-100-5p through its target NOX4. The findings highlight the importance of miR-100-5p/NOX4 axis in primary articular chondrocytes injury and provide new insights into therapeutic strategies for articular chondrocytes injury and osteoarthritis.

Abstract
Background Previous studies have shown that miR-100-5p expression is abnormal in prostate cancer. However, the role and regulatory mechanism of miR-100-5p requires further investigation. Thus, the aim of this study was to observe the effects of miR-100-5p on the proliferation, migration and invasion of prostate cancer (PCa) cells and to explore the potential related regulatory mechanism. Materials and Methods Differential miRNA expression analysis was performed using next-generation sequencing (NGS) in the patients with PCa and benign prostatic hyperplasia (BPH). The expression levels of miR-100-5p were detected using real-time fluorescence quantitative PCR (qRT-PCR). PCa cells were transfected with NC-mimics or miR-100-5p mimics, inhibitor by using liposome transfection. Moreover, the CCK-8 proliferation assay, colony formation assay, cell scratch assay and Transwell assay were used to detect the effects of miR-100-5p on cell proliferation, migration, and invasion. In addition, the target gene of miR-100-5p was verified by luciferase reporter gene assay, and the influence of miR-100-5p on the expression of mTOR mRNA by qRT-PCR and the expression of mammalian target of rapamycin (mTOR) protein was detected by western blot and immunohistochemical staining. Results Differential expression analysis of high-throughput sequencing data showed low expression of miR-100-5p in the patients of PCa. It was further confirmed by qRT-PCR that the expression of miR-100-5p in PCa cells was significantly lower than that in RWPE-1 cells (P<0.01). miR-100-5p expression in lymph node carcinoma of prostate(LNCaP) cells was markedly upregulated after transfection with miR-100-5p mimics (P<0.01), while cell proliferation, migration and invasion capacities were clearly reduced (P<0.01). mTOR mRNA and protein expression was also substantially lowered (P<0.01) and mTOR adjusted the expression of NOX4. Finally, we further confirmed by immunohistochemical staining that miR-100-5p regulated the expression of mTOR and NOX4. Conclusion miR-100-5p is expressed at low levels in PCa cells, and it can suppress PCa cell proliferation, migration and invasion, the mechanism of which is related to downregulating the expression of mTOR.

Abstract
Purpose Our research aimed to illuminate the role of miR-100-5p in chordoma and potential mechanism. Materials and Methods We used microRNA array analysis to explore differentially expressed miRNAs in chordoma tissue and then verified by qRT-PCR. Cell proliferation and transwell assay were used to evaluate the function of miR-100-5p. Cell apoptosis was analyzed by flow cytometry, and using biological software, we predicted that the insulin-like growth factor 1 receptor (IGF1R) could be the target gene of miR-100-5p, which was then validated by dual luciferase assays and Western blot. Results miR-100-5p was downregulated in chordoma tissues. Overexpression of miR-100-5p could suppress the growth of chordoma both in vitro and in vivo, and miR-100-5p could inhibit the migration and invasion of chordoma cells partially by suppressing epithelial–mesenchymal transition (EMT). Furthermore, IGF1R was validated as the target gene of miR-100-5p and expressed in most chordoma tissues. Conclusion In conclusion, our results showed that miR-100-5p was lowly expressed in chordoma and inhibited tumor malignant progression by targeting IGF1R.

Abstract
The prognostic value and molecular mechanism of microRNA-100-5p (miR-100-5p) in hepatocellular carcinoma (HCC) are still unclear. To explore the prognostic value and the mechanism of miR-100-5p in HCC, the present study analyzed the results of 18 previous studies and bioinformatic datasets. The clinical significance of miR-100-5p and its targets in HCC were investigated using The Cancer Genome Atlas and the Gene Expression Omnibus, as well as relevant literature. In total, 12 online tools were used to predict the target genes of miR-100-5p. Bioinformatics analysis and Spearman correlation analysis were performed, and genomic alterations of the hub genes were evaluated. A meta-analysis with 1,258 samples revealed that miR-100-5p was significantly downregulated in HCC [standard mean difference (SMD), −0.94; 95% confidence interval (CI), −1.14 to −0.74; I2, 35.2%]. Lower miR-100-5p expression was associated with poorer clinical characteristics and a poorer prognosis for patients with HCC. Additionally, bioinformatics analysis revealed that the ‘regulation of transcription’, ‘chromatin remodeling complex’, ‘transcription regulator activity’, ‘pathways in cancer’ and ‘heparan sulfate biosynthesis’ were the most enriched terms. Furthermore, expression of histone deacetylase (HDAC)2, HDAC3, SHC-transforming protein 1 (SHC1), Ras-related protein Rac1 (RAC1) and E3 ubiquitin-protein ligase CBL (CBL) was negatively correlated with miR-100-5p expression. Among these, upregulated HDAC2 [hazard ratio (HR), 1.910; 95% CI, 1.309–2.787; P=0.0007], HDAC3 (HR, 1.474; 95% CI, 1.012–2.146; P=0.0435), SHC1 (HR, 1.52; 95% CI, 1.043–2.215; P=0.0281) and RAC1 (HR, 1.817; 95% CI, 1.248–2.645; P=0.0022) were associated with shorter survival. Alterations in HDAC2, SHC1, RAC1 and IGF1R were linked with a poorer outcome for HCC, and alternative splicing of SHC and RAC1 were significantly decreased and increased in HCC, respectively. In summary, the downregulation of miR-100-5p may be involved in the progression and prognosis of HCC. The upregulation of HDAC2, HDAC3, SHC1 and RAC1 may indicate a poorer survival rate for patients with HCC. Thus, miR-100-5p and these 4 potential target genes may provide novel therapeutic targets and prognostic predictors for patients with HCC.

Abstract
Lung cancer causes the highest number of cancer-related deaths worldwide. Resistance to therapy is a major clinical issue contributing to the poor prognosis of lung cancer. In recent years, targeted therapy has become a concept where subgroups of non-small cell lung cancer (NSCLC) with genetically altered receptor tyrosine kinases are targeted by tyrosine kinase inhibitors (TKIs). One such subgroup harbors a gene fusion of echinoderm microtubule-associated protein-like 4 (EML4) with anaplastic lymphoma kinase (ALK). Although most NSCLC patients with EML4-ALK fusions initially respond to ALK TKI-therapy they eventually develop resistance. While ALK kinase domain mutations contribute to ALK TKI-refractoriness, they are only present in a fraction of all ALK TKI-resistant tumors. In this study we sought to explore a possible involvement of microRNAs (miRNAs) in conferring resistance to ALK TKIs in ALK TKI-refractory NSCLC cell lines. We subjected our ALK TKI-refractory cancer cells along with parental cancer cells to systematic miRNA expression arrays. Furthermore, ALK TKI-refractory cancer cells were exposed to a synthetic miRNA inhibitory Locked Nucleic Acid (LNA)-library in the presence of ALK TKIs Crizotinib or Lorlatinib. The outcome of the combined approaches uncovered miR-100-5p to confer resistance to Crizotinib and Lorlatinib in EML4-ALK NSCLC cells and to be a potential therapeutic target in drug resistance.

Abstract
Background Long noncoding RNAs (lncRNAs) are an important class of functional regulators involved in human cancers development, including gastric cancer (GC). Studying aberrantly expressed lncRNAs may provide us with new insights into the occurrence and development of gastric cancer by acting as oncogenes or tumor suppressors. In this study, we aim to examine the expression pattern of lncRNA HAGLROS in GC and its clinical significance as well as its biological role in tumor progression. Methods Bioinformatics analysis and qRT-PCR were performed to detect the relative expression of HAGLROS in GC tissues and cell lines. Gain or loss of function approaches were used to investigate the biological functions of HAGLROS. The effect of HAGLROS on proliferation was evaluated by MTT, colony formation assay and nude mouse xenograft model. Wound healing and Transwell assays were used to study the invasion and migration of GC cells. FISH, RIP, RNA-seq, Luciferase report assays, RNA pulldown and Western blot were fulfilled to measure molecular mechanisms. Results are shown as means ± S.D. and differences were tested for significance using Student’s t-test (two-tailed). Results We screened out HAGLROS, whose expression was significantly increased and correlated with outcomes of GC patients by publicly available lncRNAs expression profiling and integrating analyses. Exogenous down-regulation of HAGLROS expression significantly suppressed the cell proliferation, invasion and migration. Mechanistic investigations showed that HAGLROS was a direct target of transcriptional factor STAT3. Moreover, HAGLROS knockdown decreased mTOR expression and increased autophagy-related genes ATG9A and ATG9B expression. Further investigation showed that HAGLROS regulated mTOR signals in two manners. In the one hand, HAGLROS competitively sponged miR-100-5p to increase mTOR expression by antagonizing miR-100-5p-mediated mTOR mRNA inhibition. On the other hand, HAGLROS interacted with mTORC1 components to activate mTORC1 signaling pathway which was known to be an important negative signal of autophagy. Here activation of mTORC1 signaling pathway by HAGLROS inhibited autophagy, thereby promoted excessive proliferation and maintained the malignant phenotype of GC cells. Conclusion The present study demonstrates that HAGLROS overexpression contributes to GC development and poor prognosis and will be a target for GC therapy and further develop as a potential prognostic biomarker.

Abstract
BACKGROUND Nephroblastoma (or Wilms tumor-WT) is the most common childhood kidney cancer. In Europe, nephroblastoma is treated with preoperative chemotherapy without histological confirmation by biopsy. Therefore, minimal-invasive diagnostic markers confirming nephroblastoma diagnosis are highly warranted. PROCEDURE In our study, we aim to identify circulating miRNAs with diagnostic potential for differentiating nephroblastoma from controls. We determined the level of 19 miRNAs in serum of 32 patients with nephroblastoma and 12 controls with quantitative real-time PCR. Three miRNAs were further tested in an independent validation set including sera of patients with renal tumors other than Wilms. RESULTS In total, 14 miRNAs showed significantly higher abundance in serum of patients with nephroblastoma than in controls. The miRNAs with highest diagnostic potentials included miRs-130b-3p, -100-5p, and -143-3p with an AUC of 0.94, 0.90, and 0.89, respectively. A signature based on these three miRNAs to differentiated patients from controls with an accuracy of 84.58%, a sensitivity of 76.67%, and a specificity of 92.5%. Higher expression of miRs-100-5p and -130b-3p was confirmed in an independent validation set. The signature based on miRs-100-5p and -130b-3p differentiated patients with nephroblastoma from healthy controls with an accuracy, sensitivity, and specificity of 79.6%, 69.2%, and 90.0%, respectively. CONCLUSION In summary, we provide first evidence that serum miR-100-5p and -130b-3p hold potential as biomarker for WT irrespective of the subtype and that expression level of these miRNA in serum is unaffected by differences in serum collection.
