RESUMO

MicroRNAs have been studied extensively in neurodegenerative diseases. In a previous study, miR-153 promoted neural differentiation and projection formation in mouse hippocampal HT-22 cells. However, the pathways and molecular mechanism underlying miR-153-induced neural differentiation remain unclear. To explore the molecular mechanism of miR-153 on neural differentiation, we performed RNA sequencing on miR-153-overexpressed HT-22 cells. Based on RNA sequencing, differentially expressed genes (DEGs) and pathways in miR-153-overexpressed cells were identified. The Database for Annotation, Visualization and Integrated Discovery and Gene Set Enrichment Analysis were used to perform functional annotation and enrichment analysis of DEGs. Targetscan predicted the targets of miR-153. The Search Tool for the Retrieval of Interacting Genes and Cytoscape, were used to construct protein-protein interaction networks and identify hub genes. Q-PCR was used to detect mRNA expression of the identified genes. The expression profiles of the identified genes were compared between embryonic days 9.5 (E9.5) and E11.5 in the embryotic mouse brain of the GDS3442 dataset. Cell Counting Kit-8 assay was used to determine cell proliferation and cellular susceptibility to amyloid ß-protein (Aß) toxicity in miR-153-overexpressed cells. The results indicated that miR-153 increased cell adhesion/Ca2+ (Cdh5, Nrcam, and P2rx4) and Bdnf/Ntrk2 neurotrophic signaling pathway, and decreased ion channel activity (Kcnc3, Kcna4, Clcn5, and Scn5a). The changes in the expression of the identified genes in miR-153-overexpressed cells were consistent with the expression profile of GDS3442 during neural differentiation. In addition, miR-153 overexpression decreased cellular susceptibility to Aß toxicity in HT-22 cells. In conclusion, miR-153 overexpression may promote neural differentiation by inducing cell adhesion and the Bdnf/Ntrk2 pathway, and regulating electrophysiological maturity by targeting ion channels. MiR-153 may play an important role in neural differentiation; the findings provide a useful therapeutic direction for neurodegenerative diseases.

RESUMO

IRI often occurs after detorsion of testicular torsion, which can contribute to permanent damage to sperm production function due to spermatogonia pyroptosis. Mounting data manifest that miRNAs possess a function in the IRI progression. However, the miR-153 function in testicular IRI remains unclear. We aim to elucidate the regulatory mechanism of miR-153 in regulating spermatogonia pyroptosis in testicular IRI. We developed the mouse testicular torsion/detorsion (T/D) model and the oxygen-glucose deprivation/reperfusion (OGD/R) model to examine the miR-153 function in testicular IRI. The extent of testicular ischemic damage was evaluated through HE staining the testicular tissue. Various experimental methods, including Western blotting, QRT-PCR, MDA, SOD assays, and immunohistochemistry (IHC), were deployed to examine the miR-153 levels and the generation of ROS in the testicular tissues. Furthermore, we determined the FoxO3 levels and pyroptosis-related proteins in GC-1 cells. Cell viability was assessed using the CCK-8 assay. Finally, the connection between miR-153 and FoxO3 was verified by employing dual luciferase reporter gene assays and Ago2-RIP. In the testicular IRI, we noted a significant elevation in the pyroptosis-correlated proteins NLRP3, caspase-1 (CASP1), IL-1ß, and IL-18 levels. Furthermore, we noted a significant upregulation of miR-153 in the IRI testicular tissues and GC-1 cells treated with OGD/R, and the miR-153 upregulation increased cell pyroptosis. Conversely, the miR-153 downregulation and FoxO3 overexpression reduced cell pyroptosis. Subsequently, we validated that FoxO3 is a miR-153 target gene. During the OGD/R process, miR-153 increased cell pyroptosis in GC-1 cells by suppressing the FoxO3 expression. We identified that the regulation of testicular IRI-induced cell pyroptosis is mediated by miR-153 via its targeting of FoxO3.

RESUMO

Background: In recent years, microRNAs (miRNAs) have emerged as key players in the pathophysiology of multiple diseases including Alzheimer's disease (AD). Messenger RNA (mRNA) targeting for regulation of gene expression by miRNAs has been implicated in the annotation of disease pathophysiology as well as in the explication of their starring role in contemporary therapeutic interventions. One such miRNA is miR-153 which mediates the survival of cortical neurons and inhibits plaque formation. However, the core mRNA targets of miR-153 have not been fully illustrated. Objective: The present study aimed to elucidate the potential involvement of miR-153 in AD pathogenesis and to reveal its downstream targets. Methods: miRanda was used to identify AD-associated targets of miR-153. TargetScan, PicTar, miRmap, and miRDB were further used to validate these targets. STRING 12 was employed to assess the protein-protein interaction network while Gene ontology (GO) analysis was carried out to identify the molecular functions exhibited by these gene targets. Results: In silico analysis using miRanda predicted five important AD-related targets of miR-153, including APP, SORL1, PICALM, USF1, and PSEN1. All five target genes are negatively regulated by miR-153 and are substantially involved in AD pathogenesis. A protein interaction network using STRING 12 uncovered 30 potential interacting partners for SORL1, PICALM, and USF1. GO analysis revealed that miR-153 target genes play a critical role in neuronal survival, differentiation, exon guidance, amyloid precursor protein processing, and synapse formation. Conclusion: These findings unravel the potential role of miR-153 in the pathogenesis of AD and provide the basis for forthcoming experimental studies.

RESUMO

Background: The objective was to elucidate the potential epigenetic regulatory mechanism in HMOX1 expression in preeclampsia. Materials & methods: HMOX1 promoter DNA methylation was evaluated in the placental tissue and blood of preeclamptic and normotensive pregnant women. HMOX1 and miR-153-3p gene expression were assessed in placental tissue and peripheral blood mononuclear cells (PBMCs). Related microarray datasets in the Gene Expression Omnibus database were also analyzed. Results: In placental tissue, despite HMOX1 expression downregulation, there was no significant change in HMOX1 methylation. In PBMCs, there was no significant alteration in HMOX1 expression, while hypomethylation was observed in blood. The miR-153-3p expression increased in the placental tissue and in the PBMCs of preeclampsia. Conclusion: DNA methylation does not affect HMOX1 expression, while miR-153-3p might be a biomarker for preeclampsia.

RESUMO

BACKGROUND: To explore the role and mechanism of triptolide in regulating esophageal squamous cell carcinoma (ESCC) progression by mediating the circular RNA (circRNA)-related pathway. METHODS: The expression levels of circNOX4, miR-153-3p and special AT-rich sequence binding protein-1 (SATB1) were measured by qRT-PCR. Cell proliferation was confirmed by cell counting kit-8 assay and colony formation assay. Flow cytometry was employed to measure cell apoptosis and cell cycle process. Moreover, cell migration and invasion were detected using transwell assay. The protein levels of epithelial-mesenchymal transformation markers and SATB1 were determined by western blot analysis. Furthermore, dual-luciferase reporter assay and RIP assay were performed to confirm the interaction between miR-153-3p and circNOX4 or SATB1. Xenograft tumor models were built to verify the effects of triptolide and circNOX4 on ESCC tumor growth. RESULTS: CircNOX4 was highly expressed in ESCC tissues and cells, and its expression could be reduced by triptolide. Triptolide could inhibit ESCC proliferation, cell cycle process, migration, invasion, EMT process, and promote apoptosis, while these effects were reversed by circNOX4 overexpression. MiR-153-3p could be sponged by circNOX4, and the promotion effect of circNOX4 on the progression of triptolide-treated ESCC cells was abolished by miR-153-3p overexpression. SATB1 was a target of miR-153-3p. Also, SATB1 knockdown reversed the enhancing effect of miR-153-3p inhibitor on the progression of triptolide-treated ESCC cells. Triptolide reduced ESCC tumor growth by regulating the circNOX4/miR-153-3p/SATB1 axis. CONCLUSION: Triptolide could hinder ESCC progression, which was mainly achieved by regulating the circNOX4/miR-153-3p/SATB1 axis.

RESUMO

Circular RNAs are vital players in tumorigenesis. We held the purpose to investigate the role and mechanism of circ_0103809 in non-small cell lung cancer (NSCLC). The expressions of circ_0103809, miR-153-3p and HDAC1 mRNA were determined using quantitative real-time PCR assay, and HDAC1 protein was quantified using western blot analysis. MTT, EdU, flow cytometry, tube-formation, wound healing and tube-formation assays were conducted for functional analysis. The predicted relationship among circ_0103809, miR-153-3p and HDAC1 was ascertained using dual-luciferase analysis, RIP assay and pull-down analysis. Animal models were further constructed to realize circ_0103809's role in vivo. Circ_0103809 was upregulated NSCLC specimens, cells and serum-derived exosomes. Serum exosomal circ_0103809 had the potency to be a diagnostic biomarker for NSCLC. Circ_0103809 silencing inhibited NSCLC cell growth, metastasis and angiogenesis and triggered cell cycle arrest and apoptosis. Circ_0103809 deficiency also suppressed the growth of transplanted tumors. Circ_0103809 acted as the miR-153-3p sponge, and the biological effects of circ_0103809 knockdown were relieved by miR-153-3p inhibition. HDAC1 was directly targeted by miR-153-3p, and miR-153-3p enrichment inhibited NSCLC cell malignant phenotypes by sequestering HDAC1. Circ_0103809 knockdown repressed NSCLC malignant progression partly by regulating miR-153-3p/HDAC1 signaling.

RESUMO

Cigarettes contain various chemicals that cause damage to nerve cells. Exposure to cigarette smoke (CS) causes insulin resistance (IR) in nerve cells. However, the mechanisms for a disorder in the cigarette-induced insulin signaling pathway and in neurotoxicity remain unclear. Therefore, we evaluated, by a series of pathology analyses and behavioral tests, the neurotoxic effects of chronic exposure to CS on C57BL/6 mice. Mice exposed to CS with more than 200 mg/m3 total particulate matter (TPM) exhibited memory deficits and cognitive impairment. Pathological staining of paraffin sections of mouse brain tissue revealed that CS-exposed mice had, in the brain, neuronal damage characterized by thinner pyramidal and granular cell layers and fewer neurons. Further, the exposure of SH-SY5Y cells to cigarette smoke extract (CSE) resulted in diminished insulin sensitivity and reduced glucose uptake in a dose-dependent fashion. The PI3K/GSK3 insulin signaling pathway is particularly relevant to neurotoxicity. microRNAs are involved in the PI3K/GSK3ß/p-Tau pathway, and we found that cigarette exposure activates miR-153-3p, decreases PI3K regulatory subunits PIK3R1, and induces Tau hyperphosphorylation. Exposure to an miR-153 inhibitor or to a PI3K inhibitor alleviated the reduced insulin sensitivity caused by CS. Therefore, our results indicate that miR-153-3p, via PIK3R1, causes insulin resistance in the brain, and is involved in CS-induced neurotoxicity.

RESUMO

The early stages of ageing are a critical time window in which the ability to detect and identify precocious molecular and cognitive markers can make the difference in determining a healthy vs unhealthy course of ageing. Using the 6-different object task (6-DOT), a highly demanding hippocampal-dependent recognition memory task, we classified a population of middle-aged (12-month-old) CD1 male mice in Impaired and Unimpaired based on their short-term memory. This approach led us to identify a different microRNAs expression profile in the hippocampus of Impaired mice compared to Unimpaired ones. Among the dysregulated microRNAs, miR-153-3p was upregulated in the hippocampus of Impaired mice and appeared of high interest for its putative target genes and their possible implication in memory-related synaptic plasticity. We showed that intra-hippocampal injection of the miR-153-3p mimic in adult (3-month-old) mice is sufficient to induce a short-term memory deficit similar to that observed in middle-aged Impaired mice. Overall, these findings unravel a novel role for hippocampal miR-153-3p in modulating short-term memory that could be exploited to prevent early cognitive deficits in ageing.

RESUMO

Ischaemic stroke is a common cerebrovascular disease. Long non-coding RNA (lncRNA) of small nucleolar RNA host gene (SNHG15) has been supposedly performed a regulatory role in many diseases. Nonetheless, the function of SNHG15 in cerebral ischaemia-reperfusion injury has not been clarified. The OGD/R of Neuro2A cells simulated the ischaemic and reperfused states of the brain. Neuro2a cell line with stable transfection of plasmid with silent expression of SNHG15 was constructed. Neuro2a cell lines transfected with miR-153-3p mimic (miR-153-3p-mimics) and miR-153-3p inhibitor (miR-153-3p-inhibition) were constructed. Expression of SNHG15, mi R-200a, FOXO3 and ATG7 in mouse brain tissue and N2a cells was identified by qRT-PCR. Western blot (WB) analysis of mouse brain tissue and Neuro2a cells revealed the presence of the proteins ATG5, Cle-caspase-3, Bax, Bcl-2, LC3 II/I and P62 (WB). The representation and distribution of LC3B were observed by immunofluorescence. The death of cells was measured using a technique called flow cytometry (FACS). SNHG15 was highly expressed in cerebral ischaemia-reperfusion injury model. Down-regulation of SNHG15 lead to lower apoptosis rate and decreased autophagy. Dual luciferase assay and co-immunoprecipitation (CoIP) found lncRNA SNHG15/miR-153-3p/ATG5. Compared to cells transfected with NC suppression, cells transfected with miR-153-3p-inhibition had substantially greater overexpression of LC 3 II/I, ATG5, cle-Caspase-3, and Bax, as determined by a recovery experiment, the apoptosis rate was elevated, yet both P62 and Bcl-2 were significantly lower and LC3+ puncta per cells were significantly increased. Co-transfection of miR-153-3p-inhibition and sh-SNHG15 could reverse these results. LncRNA SNHG15 regulated autophagy and prevented cerebral ischaemia-reperfusion injury through mediating the miR-153-3p/ATG5 axis.

RESUMO

Alzheimer's disease is the most frequent neurodegenerative disease and is characterized by progressive cognitive impairment and decline. NSCs (neural stem cells) serve as beneficial and promising adjuncts to treat Alzheimer's disease. This study aimed to determine the role of miR-153-3p expression in NSC differentiation and proliferation. We illustrated that miR-153-3p was decreased and GPR55 was upregulated during NSC differentiation. IL-1ß can induce miR-153-3p expression. Luciferase reporter analysis noted that elevated expression of miR-153-3p significantly inhibited the luciferase value of the WT reporter plasmid but did not change the luciferase value of the mut reporter plasmid. Ectopic miR-153-3p expression suppressed GPR55 expression in NSCs and identified GPR55 as a direct target gene of miR-153-3p. Ectopic expression of miR-153-3p inhibited NSC growth and differentiation into astrocytes and neurons. Elevated expression of miR-153-3p induced the release of proinflammatory cytokines, such as TNF-α, IL-1ß and IL-6, in NSCs. Furthermore, miR-153-3p inhibited NSC differentiation and proliferation by targeting GPR55 expression. These data suggested that miR-153-3p may act as a clinical target for the therapeutics of neurodegenerative diseases.

RESUMO

Dysregulation of ferroptosis is involved in breast cancer progression and therapeutic responses. Inducing ferroptosis can be a potential therapeutic strategy for breast cancer treatment. Forkhead box Q1 (FOXQ1) is an oncogenic transcription factor that highly expressed and related with poor outcomes in various tumors. However, the specific effects of FOXQ1 on ferroptosis in breast cancer is unclear. In this study, we intended to explore the functions and potential mechanisms of FOXQ1 in breast cancer ferroptosis. By CCK-8, colony formation, wound healing, transwell and ferroptosis related assays, we explored the functions of FOXQ1 in breast cancer ferroptosis and progression. Through bioinformatics analysis of public database, luciferase reporter assay, RIP and ChIP assay, we investigated the potential mechanisms of FOXQ1 in breast cancer ferroptosis and progression. We found that FOXQ1 was overexpressed in breast cancer and associated with worse survival. Additionally, inhibition of FOXQ1 suppressed breast cancer ferroptosis and progression. Mechanically, we confirmed that FOXQ1 could bind to the promoter of circ_0000643 host gene to increase the levels of circ_0000643, which could sponge miR-153 and enhance the expression of SLC7A11, leading to reduced cell ferroptosis in breast cancer cells. Targeting the FOXQ1/circ_0000643/miR-153/SLC7A11 axis could be a promising strategy in breast cancer treatment.

RESUMO

Trichinellosis, a helminthic zoonosis, exhibits a cosmopolitan distribution and is a public health concern. In previous studies, it was reported that the exosomes secreted by Trichinella spiralis larvae (TsExos) largely affected cell biological activities. miRNAs, as exosome-delivered cargoes, affect the biological activities of the host by targeting genes. The present study aimed to elucidate the mechanisms by which miRNAs interact with intestinal epithelial cells. First, a miRNA library of TsExos was constructed; then, based on high-throughput miRNA sequencing results, miR-153 and its predicted target genes, namely, Agap2, Bcl2 and Pten, were selected for follow-up studies. The dual-luciferase reporter assays revealed that miR-153 directly targeted Bcl2 and Pten. Furthermore, real-time qPCR and Western blotting revealed that only Bcl2 was downregulated by TsExo-delivered miR-153 in porcine intestinal epithelial cells (IPEC-J2). Bcl2, an important antiapoptotic protein, plays an essential role in cell apoptosis as a common intersecting molecule of various signal transduction pathways. Therefore, we hypothesized that miR-153 derived from TsExos causes cell apoptosis by targeting Bcl2. The results suggested that miR-153 could induce apoptosis, reduce mitochondrial membrane potential, affect cell proliferation, and cause damage and substantial oxidative stress. Furthermore, miR-153 coincubated with IPEC-J2 cells stimulated the accumulation of the proapoptotic proteins Bax and Bad, which belong to the Bcl2 family of proteins, and the apoptosis-implementing proteins Caspase 9 and Caspase 3. Moreover, studies have suggested that miR-153 can promote apoptosis by regulating the MAPK and p53 signalling pathways involved in apoptosis. Thus, exosome-mediated miR-153 delivery secreted by T. spiralis could induce apoptosis and affect the MAPK and p53 signalling pathways by downregulating Bcl2 in IPEC-J2 cells. The study highlights the mechanisms underlying the invasion of T. spiralis larva.

RESUMO

Helicobacter pylori (H. pylori) infection plays a pivotal role in the development of gastric cancer (GC). However, the association between aberrant microRNAs (miRNAs/miRs) expression and H. pylori­induced GC remains poorly understood. The present study reported that repeated infection of H. pylori caused the oncogenicity of GES­1 cells in BALB/c Nude mice. miRNA sequencing revealed that both miR­7 and miR­153 were significantly decreased in the cytotoxin­associated gene A (CagA) positive GC tissues and this was further confirmed in a chronic infection model of GES­1/HP cells. Further biological function experiments and in vivo experiments validated that miR­7 and miR­153 can promote apoptosis and autophagy, inhibit proliferation and inflammatory response in GES­1/HP cells. All the associations between miR­7/miR­153 and their potential targets were revealed via bioinformatics prediction and dual­luciferase reporter assay. Particularly, downregulation of both miR­7 and miR­153 obtained an improved sensitivity and specificity in diagnosing H. pylori (CagA+)­induced GC. The present study identified that the combination of miR­7 and miR­153 may be regarded as novel therapeutic targets in H. pylori CagA (+)­associated GC.

RESUMO

BACKGROUND: Lupus nephritis (LN) is one of the most common and serious complications of systemic lupus erythematosus. Our experiments aimed to evaluate the molecular mechanisms of long noncoding RNA (lncRNA) TUG1 in a human renal mesangial cell (HRMC) model of LN. METHODS: Cells were treated with lipopolysaccharide (LPS) to induce inflammatory damage. StarBase, TargetScan, and a luciferase reporter assay were used to predict and confirm the interactions between lncRNA TUG1, miR-153-3p, and Bcl-2. We determined the lncRNA TUG1 and miR-153-3p levels in LPS-induced HRMCs using quantitative reverse transcription PCR (RT-qPCR). MTT and flow cytometry analyses were used to detect HRMC proliferation and apoptosis, respectively. In addition, the expression of the apoptosis-related proteins Bax and Bcl-2 was evaluated using western blot analysis and RT-qPCR. Lastly, the secretion of inflammatory cytokines (IL-1ß, IL-6, and TNF-α) was assessed using ELISA. RESULTS: miR-153-3p directly targeted lncRNA TUG1. The level of lncRNA TUG1 was remarkably lower and miR-153-3p expression was markedly higher in LPS-treated HRMCs than in untreated cells. Transfection with TUG1-plasmid relieved LPS-induced HRMC injury, as evidenced by increased cell viability, inhibited apoptotic cells, reduced Bax expression, increased Bcl-2 level, and reduced secretion of inflammatory cytokines. Importantly, these findings were reversed by miR-153-3p mimic. We also found that miR-153-3p directly targeted Bcl-2 and negatively regulated Bcl-2 expression in HRMCs. In addition, our findings suggest that miR-153-3p inhibitor relieved LPS-induced HRMC injury via the upregulation of Bcl-2. CONCLUSION: lncRNA TUG1 alleviated LPS-induced HRMC injury through regulation of the miR-153-3p/Bcl-2 axis in LN.

RESUMO

Breast cancer is considered the solid tumor most sensitive to chemotherapy. However, it can become resistant to various chemotherapeutic drugs, including doxorubicin, which triggers cell death by intercalation between DNA bases, free radical formation, and topoisomerase II inhibition. When drug resistance develops, several miRNAs are dysregulated, suggesting that miRNAs may play a significant role in resistance formation. In the current study, we investigated how doxorubicin sensitivity of breast cancer cells is affected by miR-153-3p and its target gene. The MTT method was used to determine the chemo-sensitizing effect of miR-153-3p on doxorubicin in MCF-7 and MDA-MB-231 cell lines. Results of Western blot and dual luciferase confirmed that miR-153-3p targets KIF20A and decreases its expression. Transwell and flow cytometry experiments showed that miR-153-3p and doxorubicin together had higher effects on MCF-7 and MDA-MB-231 cell proliferation, migration, and invasion, as well as increasing apoptosis and arresting cells in the G1 phase. Proteins related to apoptosis and the cell cycle exhibited the same tendency. Intracellular vesicle formation was inhibited and RAB26 was also downregulated by treatment with miR-153-3p alone or in combination with doxorubicin. Doxorubicin's ability to suppress tumors may be enhanced by miR-153-3p, according to in vivo studies. According to our findings, miR-153-3p has a direct effect on KIF20A and may regulate the formation of intracellular vesicles, which in turn makes breast cancer cells more susceptible to doxorubicin.

RESUMO

Introduction: Prostate cancer (PC) is one of the most frequently diagnosed cancers in males. MiR-153, as a member of the microRNA (miRNA) family, plays an important role in PC. This study aims to explore the expression and possible molecular mechanisms of the miR-153 action. Methods: Formalin-fixed paraffin-embedded (FFPE) tissues were collected from prostatectomy specimens of 29 metastatic and 32 initial stage PC patients. Expression levels of miR-153 were measured using real-time reverse transcription polymerase chain reaction (qRT-PCR). 2-ΔΔCT method was used for quantitative gene expression assessment. The candidate target genes for miR-153 were predicted by TargetScan. Mutations in target genes of miR-153 were identified using exome sequencing. Protein-protein interaction (PPI) networks, Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to investigate the potential molecular mechanisms of miR-153 in PC. Results: MiR-153 was significantly up-regulated in PC tissues compared to non-cancerous tissues. The analysis of correlation between the expression level of miR-153 and clinicopathological factors revealed a statistically significant correlation with the stage of the tumor process according to tumor, node, metastasis (TNM) staging system (p = 0.0256). ROC curve analysis was used to evaluate the predictive ability of miR-153 for metastasis development and it revealed miR-153 as a potential prognostic marker (AUC = 0.85; 95%CI 0.75-0.95; sensitivity = 0.72, specificity = 0.86)). According to logistic regression model the high expression of miR-153 increased the risk of metastasis development (odds ratios = 3.14, 95% CI 1.62-8.49; p-value = 0.006). Whole exome sequencing revealed nonsynonymous somatic mutations in collagen type IV alpha 1 (COL4A1), collagen type IV alpha 3 (COL4A3), forkhead box protein O1 (FOXO1), 2-hydroxyacyl-CoA lyase 1 (HACL1), hypoxia-inducible factor 1-alpha (HIF-1A), and nidogen 2 (NID2) genes. Moreover, KEGG analysis revealed that the extracellular matrix-receptor (ECM-receptor) interaction pathway is mainly involved in PC.

RESUMO

Treatment of neurological disorders has always been one of the challenges facing scientists due to poor prognosis and symptom overlap, as well as the progress of the disease process. Neurological disorders such as Huntington's, Parkinson's, Alzheimer's diseases, and Amyotrophic Lateral Sclerosis are very debilitating. Therefore, finding a biomarker is essential for early diagnosis and treatment goals. Recent studies have focused more on molecular factors and gene manipulation to find effective diagnostic and therapeutic biomarkers. Among these factors, microRNAs (miRNAs/ miRs) have attracted much attention. On the other hand, a growing correlation between miRNAs and neurological disorders has caused scientists to consider it as a diagnostic and therapeutic target. In this line, the miR-153 is one of the most important and highly conserved miRNAs in mice and humans, whose expression level is not only altered in neurological disorders but also improves neurogenesis. MiR-153 can regulate multiple biological processes by targeting various factors. Furthermore, the miR-153 expression also can be regulated by important regulators, such as long non-coding RNAs (e.g., KCNQ1OT1) and some compounds (e.g., Tanshinone IIA) altering the expression of miR-153. Given the growing interest in miR-153 as a biomarker and therapeutic target for neurological diseases as well as the lack of comprehensive investigation of miR-153 function in these disorders, it is necessary to identify the downstream and upstream targets and also it's potential as a therapeutic biomarker target. In this review, we will discuss the critical role of miR-153 in neurological disorders for novel diagnostic and prognostic purposes and its role in multi-drug resistance.

RESUMO

Head and neck squamous cell carcinoma (HNSCC) is a heterogeneous and aggressive tumor with high mortality and unfavorable prognosis. Numerous long non-coding RNAs (lncRNAs) have been confirmed to exert pivotal parts in cancers. Nevertheless, the functions of most lncRNAs in HNSCC need deeper exploration. Our present research tried to clarify the biological role of TM4SF19 antisense RNA 1 (TM4SF19-AS1) and investigate its regulatory mechanism in HNSCC. RT-qPCR analysis was done to test TM4SF19-AS1 expression and identify the up-regulation of TM4SF19-AS1 in HNSCC cells. Loss-of-function assays were also involved, and the data implied that TM4SF19-AS1 knockdown hampered the proliferation, migration, invasion, along with epithelial-mesenchymal transition (EMT) of HNSCC cells. In vivo assays revealed TM4SF19-AS1 depletion restrained HNSCC tumor growth. Additionally, mechanism experiments were implemented to uncover the underlying regulatory mechanism of TM4SF19-AS1 in HNSCC cells. It turned out that TM4SF19-AS1 modulated laminin subunit gamma 1 (LAMC1) expression via sequestering microRNA-153-3p (miR-153-3p) and recruiting heterogeneous nuclear ribonucleoprotein C (HNRNPC) protein. Rescue assays confirmed that TM4SF19-AS1 contributed to HNSCC cell malignant behaviors via up-regulating LAMC1. To summarize, TM4SF19-AS1 played an oncogenic role in HNSCC cells, signifying TM4SF19-AS1 may have the potential to be used as a novel molecular target for HNSCC diagnosis.

RESUMO

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.
