Abstract
Wilms' tumor is a malignant renal cancer that arises within the pediatric urinary system. This study intended to investigate how a novel long non-coding RNA LINC01339 functions in the pathogenesis of Wilms' tumor. An elevated miR-135b-3p expression as well as reduced levels of LINC01339 and ADH1C were observed in Wilms' tumor. LINC01339 mediated ADH1C expression by directly binding to miR-135b-3p. The enforced LINC01339 or ADH1C markedly hindered cell growth and migration in Wilms' tumor. The LINC01339 overexpression also repressed the growth of Wilms' tumors in vivo, whereas miR-135b-3p overexpression exerted the opposite effects on Wilms' tumor cells in vitro. Additionally, upregulating miR-135b-3p reversed LINC01339's effects on the cellular processes of Wilms' tumor cells, whereas ADH1C overexpression offset the cancer-promoting influence of miR-135b-3p upregulation on Wilms' tumor progression. Therefore, LINC01339 prevents Wilms' tumor progression by modulating the miR-135b-3p/ADH1C axis. Our findings substantiate that the LINC01339/miR-135 b-3p/ADH1C regulatory axis has potential to be a target for the treatment of Wilms' tumor.

Unveiling the Potential of Serum MiR-483-5p: A Promising Diagnostic and Prognostic Biomarker in OLP and OSCC Patients by In silico Analysis of Differential Gene Expression. Curr Pharm Des 2024; 30:310-322. [PMID: 38310566 DOI: 10.2174/0113816128276149240108163407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 12/09/2023] [Accepted: 12/15/2023] [Indexed: 02/06/2024]
Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) and oral lichen planus (OLP) are two separate conditions affecting the mouth and result in varying clinical outcomes and levels of malignancy. Achieving early diagnosis and effective therapy planning requires the identification of reliable diagnostic biomarkers for these disorders. MicroRNAs (miRNAs) have recently received attention as powerful biomarkers for various illnesses, including cancer. In particular, miR-483-5p is a promising diagnostic and prognostic biomarker in various cancers. Therefore, this study aimed to investigate the role of serum miR-483-5p in the diagnosis and prognosis of OLP and OSCC patients by in silico analysis of differential gene expression. METHODS GSE23558 and GSE52130 data sets were selected, and differential gene expression analysis was performed using microarray data from GSE52130 and GSE23558. The analysis focused on comparing OLP and OSCC samples with normal samples. The genes intersected through the differential gene expression analysis were then extracted to determine the overlapping genes among the upregulated or downregulated DEGs. The downregulated genes among the DEGs were subsequently imported into the miRWalk database to search for potential target genes of miRNA 483-5p that lacked validation. To gain insight into the biological pathways associated with the DEGs, we conducted pathway analysis utilizing tools, such as Enrichr. Additionally, the cellular components associated with these DEGs were investigated by analyzing the String database. On the other hand, blood serum samples were collected from 35 OSCC patients, 34 OLP patients, and 34 healthy volunteers. The expression level of miR-483-5p was determined using quantitative reverse transcription polymerase chain reaction (RT-qPCR). The Kruskal-Wallis test was utilized to investigate the considerable correlation. Moreover, this study explored the prognostic value of miR-483-5p through its association with clinicopathological parameters in OSCC patients. RESULTS The results showed that serum expression of miR-483-5p was considerably higher in OSCC patients compared to OLP patients and healthy controls (p 0.0001) and that this difference was statistically significant. Furthermore, elevated miR-483-5p expression was associated with tumor size, lymph node metastasis, and stage of tumor nodal metastasis in OSCC patients (p 0.001, p 0.038, and p 0.0001, respectively). In silico analysis found 71 upregulated genes at the intersection of upregulated DEGs and 44 downregulated genes at the intersection of downregulated DEGs, offering insight into the potential underlying mechanisms of miR-483-5p's engagement in OSCC and OLP. The majority of these DEGs were found to be involved in autophagy pathways, but DEGs involved in the histidine metabolism pathway showed significant results. Most of these DEGs were located in the extracellular region. After screening for downregulated genes that were invalidated, miRNA 483-5p had 7 target genes. CONCLUSION This study demonstrates the potential of serum miR-483-5p as a promising diagnostic and prognostic biomarker in OSCC and OLP patients. Its upregulation in OSCC patients and its association with advanced tumor stage and potential metastasis suggest the involvement of miR-483-5p in critical signaling pathways involved in cell proliferation, apoptosis, and cell cycle regulation, making it a reliable indicator of disease progression. Nevertheless, additional experimental studies are essential to validate these findings and establish a foundation for the advancement of targeted therapies and personalized treatment approaches.

Abstract
Our study aimed to identify relevant transcriptomic biomarkers for the Wilms tumor, the most common pediatric kidney cancer, independent of the histological type and stage. Using next-generation sequencing, we analyzed the miRNA profiles of 74 kidney samples, which were divided into two independent groups: fresh frozen tissue and formalin-fixed paraffin-embedded tissue samples. Subsequent mRNA expression profiling and pathway analysis were performed to establish the interplay and potential involvement of miRNAs and mRNA in the Wilms tumor. Comparative analysis, irrespective of post-dissection tissue processing, revealed 41 differentially expressed miRNAs, with 27 miRNAs having decreased expression and 14 miRNAs having increased expression in the Wilms tumor tissue compared to healthy kidney tissue. Among global mRNA transcriptomic profile differences, cross-sectional analysis suggested a limited list of genes potentially regulated by differentially expressed miRNAs in the Wilms tumor. This study identified the comprehensive miRNA and mRNA profile of the Wilms tumor using next-generation sequencing and bioinformatics approach, providing better insights into the pathogenesis of the Wilms tumor. The identified Wilms tumor miRNAs have potential as biomarkers for the diagnosis and treatment of the Wilms tumor, regardless of histological subtype and disease stage.

Small-Extracellular-Vesicle-Derived miRNA Profile Identifies miR-483-3p and miR-326 as Regulators in the Pathogenesis of Antiphospholipid Syndrome (APS). Int J Mol Sci 2023; 24:11607. [PMID: 37511365 PMCID: PMC10380201 DOI: 10.3390/ijms241411607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 07/06/2023] [Accepted: 07/17/2023] [Indexed: 07/30/2023] Open
Abstract
Primary antiphospholipid syndrome (PAPS) is a systemic autoimmune disease associated with recurrent thrombosis and/or obstetric morbidity with persistent antiphospholipid antibodies (aPL). Although these antibodies drive endothelial injury and thrombophilia, the underlying molecular mechanism is still unclear. Small extracellular vesicles (sEVs) contain miRNAs, key players in intercellular communication. To date, the effects of miRNA-derived sEVs in PAPS are not well understood. We characterised the quantity, cellular origin and miRNA profile of sEVs isolated from thrombotic APS patients (PAPS, n = 50), aPL-carrier patients (aPL, n = 30) and healthy donors (HD, n = 30). We found higher circulating sEVs mainly of activated platelet origin in PAPS and aPL patients compared to HD, that were highly engulfed by HUVECs and monocyte. Through miRNA-sequencing analysis, we identified miR-483-3p to be differentially upregulated in sEVs from patients with PAPS and aPL, and miR-326 to be downregulated only in PAPS sEVs. In vitro studies showed that miR-483-3p overexpression in endothelial cells induced an upregulation of the PI3K-AKT pathway that led to endothelial proliferation/dysfunction. MiR-326 downregulation induced NOTCH pathway activation in monocytes with the upregulation of NFKB1, tissue factor and cytokine production. These results provide evidence that miRNA-derived sEVs contribute to APS pathogenesis by producing endothelial cell proliferation, monocyte activation and adhesion/procoagulant factors.

Abstract
Wilms tumor (WT) as the most frequent pediatric tumor of kidney has been shown to be associated with dysregulation of non-coding RNAs. miR-200c, miR-155-5p, miR-1180, miR-22-3p, miR-483-5p, miR-140-5p, miR-92a-3p, miR-483-3p, miR-572, miR-539 and miR-613 are among dysregulated miRNAs in this tumor. Moreover, a number of long non-coding RNAs such as CRNDE, XIST, SNHG6, MEG3, LINC00667, MEG8, DLGAP1-AS2 and SOX21-AS1 have been shown to be dysregulated in WT. Finally, distinct studies have reported down-regulation of circCDYL and up-regulation of circ0093740 and circSLC7A6 in this tumor. Dysregulation of these transcripts represents a new avenue for identification of the pathetiology of this pediatric tumor as well as design of targeted therapies.

Abstract
MicroRNAs (miRNAs) belong to a class of endogenous small noncoding RNAs that regulate gene expression at the posttranscriptional level, through both translational repression and mRNA destabilization. They are key regulators of kidney morphogenesis, modulating diverse biological processes in different renal cell lineages. Dysregulation of miRNA expression disrupts early kidney development and has been implicated in the pathogenesis of developmental kidney diseases. In this Review, we summarize current knowledge of miRNA biogenesis and function and discuss in detail the role of miRNAs in kidney morphogenesis and developmental kidney diseases, including congenital anomalies of the kidney and urinary tract and Wilms tumor. We conclude by discussing the utility of miRNAs as potentially novel biomarkers and therapeutic agents.

Abstract
Wilms tumor is the most common pediatric abdominal solid tumor, and its treatment has been a focus of research. For now, the 5-year survival rate of children with Wilms tumor is about 90%. It is difficult to make further progress simply by the improvement of the existing treatments (multi-modal therapy). Therefore, targeted therapy and immunotherapy which have high accuracy and few side effects began to be considered for the treatment of Wilms tumor. At present, though targeted therapy and immunotherapy are rarely used in the treatment of Wilms tumor except in clinical trials, there are dozens of clinical trials research them around the world. The sites in targeted therapy research are mainly focused on insulin-like growth factor 2 (IGF2) pathway, anti-angiogenesis, phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway, and some miRNAs, etc. And there are three types of study in Wilms tumor immunotherapy, which are inhibition of the COX-2 pathway, chimeric antigen receptor (CAR)-T cell therapy, and multi-tumor associated antigen (TAA)-specific cytotoxic T lymphocytes (CTL) therapy. Among them, the phase I clinical trial of multi-TAA-specific CTL (MTAA-CTL) therapy has been completed, and the results are very satisfactory. In this narrative review, we review the basic research and relevant clinical research on targeted therapy and immunotherapy for Wilms tumor.

Abstract
PURPOSE Compelling evidence has unveiled the importance of long noncoding RNAs (lncRNAs) in malignant behavior of Wilms' tumor (WT). Hereon, we intend to assess the function and associated molecular mechanism of lncRNA maternally expressed gene 8 (MEG8) in WT cells. METHODS Expression levels of MEG8, miR-23a-3p, and CT10 regulator of kinase (CRK) were determined by quantitative real-time polymerase chain reaction. Cell viability was assessed by MTT assay. Besides, wound healing assay and transwell assay were applied to examine abilities of cell migration and invasion, respectively. Dual-luciferase reporter assay was employed to test the interplay among MEG8, miR-23a-3p, and CRK. Western blot was used to detect relative protein expression of CRK. RESULTS MEG8 and CRK expression was elevated, while miR-23a-3p expression was decreased in WT tissues and cells. The histologic type, lymphatic metastasis, and National Wilms Tumor Study (NWTS) stage were associated with the expression of MEG8, miR-23a-3p, and CRK in WT patients. MEG8 knockdown or miR-23a-3p overexpression restrained WT cells in cell viability, migration, and invasiveness in vitro. As to mechanism exploration, MEG8 could directly bind to miR-23a-3p and then miR-23a-3p targeted CRK. MEG8 was inversely correlated with miR-23a-3p and positively correlated with CRK in WT tissues. Meantime, miR-23a-3p was inversely correlated with CRK in WT tissues. Additionally, MEG8 knockdown-mediated suppressive impacts on cell viability, migration, and invasiveness were reversed by overexpression of CRK or repression of miR-23a-3p in WT cells. CONCLUSIONS The cell viability, migration, and invasiveness of WT cells were repressed by MEG8 knockdown via targeting the miR-23a-3p/CRK axis.

Abstract
Wilms tumor is a rare kidney malignancy primarily developed in children. Treatment for Wilms tumor includes surgery, radiotherapy, and chemotherapy. Recent studies have demonstrated that microRNAs (miRNAs) play important roles in regulating Wilms tumor development. In this study, we aimed to elucidate the expression and function of miR-378c in Wilms tumor. Quantitative real-time PCR (qRT-PCR) results showed that miR-378c was downregulated in Wilms tumor tissues and cell lines. Functionally, further CCK-8, would healing, and transwell assays revealed that overexpression of miR-378c impaired Wilms tumor cell growth and metastasis in vitro. In addition, xenograft assay showed that miR-378c overexpression inhibited Wilms tumor development in vivo. Mechanistically, luciferase reporter assay confirmed that miR-378c directly targets CAMKK2 in Wilms tumor. qRT-PCR and western blot assays demonstrated that CAMKK2 was highly expressed in Wilms tumor tissues and cell lines. Rescue experiments were performed to further evaluate the functional relationship between miR-378c and CAMKK2. Overexpression of miR-378c suppressed Wilms tumor cell metastasis via negatively regulating CAMKK2 expression. Consistently, inhibition of miR-378c enhanced Wilms tumor cell malignancy behavior via augmenting CAMKK2 expression, which could be abrogated by CAMKK2 knockdown. In summary, our findings suggest that miR-378c inhibits the development and metastasis of Wilms tumor via negatively regulating CAMKK2 expression, which could be utilized to develop new therapy strategy.

Abstract
BACKGROUND Menopause leads to estradiol (E2) deficiency that is associated with decreases in muscle mass and strength. Here we studied the effect of E2 deficiency on microRNA (miR) signaling that targets apoptotic pathways. METHODS C57BL6 mice were divided into control (normal estrous cycle, n = 8), OVX (E2 deficiency, n = 7) and OVX + E2 groups (E2-pellet, n = 4). Six weeks following the OVX surgery, mice were sacrificed and RNA isolated from gastrocnemius muscles. miR-profiles were studied with Next-Generation Sequencing (NGS) and candidate miRs verified using qPCR. The target proteins of the miRs were found using in silico analysis and measured at mRNA (qPCR) and protein levels (Western blot). RESULTS Of the apoptosis-linked miRs present, eleven (miRs-92a-3p, 122-5p, 133a-3p, 214-3p, 337-3p, 381-3p, 483-3p, 483-5p, 491-5p, 501-5p and 652-3p) indicated differential expression between OVX and OVX + E2 mice in NGS analysis. In qPCR verification, muscle from OVX mice had lower expression of all eleven miRs compared with OVX + E2 (p < 0.050). Accordingly, OVX had higher expression of cytochrome C and caspases 6 and 9 compared with OVX + E2 at the mRNA level (p < 0.050). At the protein level, OVX also had lower anti-apoptotic BCL-W and greater pro-apoptotic cytochrome C and active caspase 9 compared with OVX + E2 (p < 0.050). CONCLUSION E2 deficiency downregulated several miRs related to apoptotic pathways thus releasing their targets from miR-mediated suppression, which may lead to increased apoptosis and contribute to reduced skeletal muscle mass.

Abstract
Doxorubicin is a chemotherapeutic agent that inhibits topoisomerase II, intercalates within DNA base pairs and results in oxidative DNA damage, thus inducing cell apoptosis. Although it is effective in the treatment of a wide range of human cancers, the emergence of resistance to this drug can increase tumour growth and impact patients' survival. Numerous molecular mechanisms and signalling pathways have been identified that induce resistance to doxorubicin via stimulation of cell proliferation, cell cycle switch and preclusion of apoptosis. A number of microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) have also been identified that alter sensitivity to doxorubicin. Understanding the particular impact of these non-coding RNAs in conferring resistance to doxorubicin has considerable potential to improve selection of chemotherapeutic regimens for cancer patients. Moreover, modulation of expression of these transcripts is a putative strategy for combating resistance. In the current paper, the influence of miRNAs and lncRNAs in the modification of resistance to doxorubicin is discussed.

[PMID: 33357780 DOI: 10.1016/j.jphs.2020.10.002] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 09/07/2020] [Accepted: 10/08/2020] [Indexed: 12/19/2022] Open
Abstract
OBJECTIVE Treatment with the chemotherapeutic agent, doxorubicin (DOX), is limited by side effects. We have previously demonstrated that fasudil, a Rho/ROCK inhibitor, has antioxidant, anti-inflammatory and anti-apoptotic effects in contrast-induced acute kidney injury model. The present study to investigated the possible protective effect of fasudil, on DOX-induced nephrotoxicity. MATERIALS AND METHOD In vivo: Forty male C57BL/6 male mice were randomly divided into 4 groups: Control group, DOX treatment group (DOX group), DOX + low dose fasudil (DOX + L group), DOX + high dose fasudil (DOX + H group). Mice in 2-4 groups received DOX (2.5 mg/kg, i.p.) once a week for 8 weeks. The 3 and 4 group were given 2 mg/kg/d or 10 mg/kg/d fasudil before DOX injection. respectively. Meanwhile, the control group received saline. At the end of week eight, blood samples were collected for biochemical testing. The kidneys were removed for histological, immunohistochemical, Western blot, quantitative real-time PCR (qRT-PCR), and molecular detection. In vitro: NRK-52E cells were treated with 40 uM fasudil for 12 h, then incubated with 1 uM DOX for 24 h. Cells then collected for qRT-PCR and Western blot. RESULTS In vivo, fasudil treatment ameliorated DOX-induced immunofluorescence reaction of DNA damage-related factors (8-OHdG), decreased the expression of Bax, Caspase-3, p16, p21 and p53, and increased the expression of protein of Bcl-2, Bmi-1 and Sirt-1. In the mouse model, administration of fasudil significantly ameliorated DOX-induced kidney damage, suppressed cell apoptosis and senescence, ameliorated redox imbalance and DNA damage. At the same time, DOX produced obvious kidney damage revealed by kidney functions changes: increased serum creatinine (SCr) and blood urea nitrogen (BUN) concentrations. In addition, kidney tissue staining in the DOX group showed abnormal structure and fibroproliferative disorders. And DOX could promote the oxidation and senescence of kidney cells, leading to increased expression of 8-OHdG and senescence and apoptosis-related factors. On the contrary, fasudil treatment can effectively inhibit redox imbalance and DNA damage caused by DOX, and inhibit cell senescence and apoptosis. Fasudil can inhibit excessive activation of Rho/ROCK signaling pathway, thereby improving kidney tissue fibrosis and recovery kidney function. CONCLUSION Fasudil has a protective effect on DOX-induced nephrotoxicity in mice and NRK-52E cells, which can inhibit oxidative stress and DNA damage, inhibit apoptosis, and delays cell senescence by inhibiting RhoA/Rho kinase (ROCK) signaling pathway.

Abstract
Background Wilms tumor (WT) is an embryonic malignant tumor, and its related mechanism is still unclear. microRNA (miR), as a short-chain non-coding RNA, has low expression in various tumors. In this study, WT differential miR was screened by multi-chip in GEO database and its mechanism was explored to provide potential therapeutic targets and ideas for clinic. Methods We logged into GEO database and downloaded GSE57370 and GSE48137 chip matrix files to analyze potential differences in miR. TargetScan, miRDB, miRTarBase and starBase were applied to predict the target genes of miR with significant differences. qRT-PCR was applied to determine the expression of miR-30d and Sox4 in WT tissue and cell line (G401). The interaction of miR-30d with Sox4 was confirmed by qRT-PCR, Western blot and luciferase assay, respectively. CCK-8, Transwell and flow cytometry were applied to determine the proliferation, invasion, migration and apoptosis of cells. Results We found that miR-30d was low expressed in two chips. qRT-PCR showed that miR-30d was down-regulated and SOX4 was up-regulated in WT tissues and cells. The online target gene prediction software showed there was a targeted binding site between Sox4 and miR-30d. Sox4 was negatively controlled by miR-30d. Subsequent studies found that over-expression of miR-30d inhibited the proliferation, invasion, migration and induced apoptosis of C64 and WiT49 cells. In addition, Sox4 could reverse the proliferation, invasion and migration of C64 and WiT49 induced by miR-30d and induce apoptosis. Conclusion miR-30d is poorly expressed in WT and can induce apoptosis and inhibit proliferation, invasion and migration by mediating Sox4.

Abstract
Objective Glioma is the most common malignant brain tumor that has high aggressiveness. The aim of this study was to investigate the potential therapeutic targets for gliomas. Materials and Methods Real-time quantitative polymerase chain reaction (RT-qPCR) was employed to calculate the expression of miRNA and genes. The connection between the expression of miR-483 and patients' overall survival rate was evaluated using Kaplan-Meier analysis. In addition, the underlying mechanism was detected using luciferase assay. Results The expression level of miR-483 was significantly decreased in glioma tissue samples and cell lines, compared to the adjacent tissues and normal cell lines. Downregulation of miR-483 or upregulation of SOX3 was associated with overall survival of glioma patients. Additionally, overexpression of miR-483 promotes cell invasion and migration and inhibits apoptosis. In addition, miR-483 directly targeted to SOX3, and the expression of miR-483 has a negative correlation with SOX3 in glioma tissues. SOX3 reversed partial functions of miR-483 on cell migration, invasion, and promoted cell apoptosis in glioma. Conclusion MiR-483 inhibited glioma cell migration, invasion, and promoted glioma cell apoptosis by targeting SOX3. MiR-483 maybe acted as a potential target for the treatment of glioma.

Abstract
SNAIL (SNAI1) is a zinc finger transcription factor that binds to E-box sequences and regulates the expression of genes. It usually acts as a gene repressor, but it may also activate the expression of genes. SNAIL plays a key role in the regulation of epithelial to mesenchymal transition, which is the main mechanism responsible for the progression and metastasis of epithelial tumors. Nevertheless, it also regulates different processes that are responsible for tumor growth, such as the activity of cancer stem cells, the control of cell metabolism, and the regulation of differentiation. Different proteins and microRNAs may regulate the SNAIL level, and SNAIL may be an important regulator of microRNA expression as well. The interplay among SNAIL, microRNAs, long non-coding RNAs, and circular RNAs is a key event in the regulation of tumor growth and metastasis. This review for the first time discusses different types of regulation between SNAIL and non-coding RNAs with a focus on feedback loops and the role of competitive RNA. Understanding these mechanisms may help develop novel therapeutic strategies against cancer based on microRNAs.
