[PMID: 32823234 DOI: 10.1016/j.prp.2020.153152] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Revised: 07/26/2020] [Accepted: 07/28/2020] [Indexed: 02/05/2023]
Abstract
BACKGROUND Renal cell carcinoma (RCC) accounts for 3 % of cancer patients. Early detection influences the therapeutic strategy and significantly improves patients' survival rates. Stable existing circulating miRNAs could be a promising diagnostic biomarker. METHODS Previously our team demonstrated the anti-tumor effect of miR-20b-5p, miR-30a-5p and miR-196a-5p in RCC tissue and cell lines. Here, based on 110 RCC patients and 110 health control, we investigated serum expression of these three miRNAs in the testing set and the validation set separately by using quantitative real-time PCR. A three-miRNA panel with high diagnostic efficiency was constructed. Correlations between these miRNAs and clinical parameters were investigated. Additionally, the TCGA dataset and bioinformatic analysis are used for the functional exploration of these miRNAs. RESULTS Serum expression levels of miR-20b-5p, miR-30a-5p were significantly reduced in RCC patients, while miR-196a-5p expression level was up-regulated (p < 0.001). miR-20b-5p, miR-30a-5p and miR-196a-5p had moderate diagnostic ability for RCC (AUC = 0.807, 0.766 and 0.719 in the testing set, respectively). The AUC of the three-miRNA panel was 0.949 in the testing set and 0.938 in the validation set. Specifically, the serum expression level of miR-196a-5p was significantly down-regulated in RCC patients with higher Fuhrman grade (p = 0.051). TCGA dataset analysis showed that the three-miRNA panel probably participated in RCC by targeting ITGA4 and NRP2. CONCLUSION The three-miRNA panel could serve as a promising non-invasive biomarker for RCC detection.

Abstract
BACKGROUND Renal cell carcinoma (RCC) is a renal parenchyma neoplasm with a 30% recurrence rate even when treated properly. MicroRNAs are noncoding small RNAs that are involved in cellular communication and may participate in cancer development. This study aimed to explore the relationship between miR-33b-5p expression and RCC progression and prognosis. METHOD RT-qPCR, CCK-8 assay, wound scratch assay, transwell assay and flow cytometry assay were used to evaluate the expression and function of miR-33b-5p in RCC. Additionally, RCC samples and survival data from The Cancer Genome Atlas were used to analyze the prognostic functions of miR-33b-5p. RESULTS miR-33b-5p expression in RCC tissues and cell lines (786-O, ACHN) were found to be significantly downregulated, compared with normal tissues and cell lines (P<0.001). The miR-33b-5p mimic transfected cells showed a slower proliferation rate (P<0.01), while its invasion ability decreased by 38.16% (786-O, P<0.001) and 49.19% (ACHN, P<0.05), compared with the negative control (NC). The migration ability of both RCC lines were found to be as follows: miR-33b-5p inhibitor > NC or NC inhibitor > miR-33b-5p mimic. Additionally, TCGA and RCC samples reveal that low miR-33b-5p expression is related to poor survival outcomes (univariate analysis, P=0.029; multivariate analysis, P=0.024; Kaplan-Meier survival curves, P=0.014). Target genes prediction suggests that miR-33b-5p performs its tumor-suppressive effects and prognostic role through targeting TBX15, SLC12A5, and PTGFRN. CONCLUSIONS miR-33b-5p may function as a tumor-suppressive regulator and prognostic biomarker in RCC.

Abstract
microRNAs (miRNAs), as a group of noncoding RNAs, posttranscriptionally control gene expression by binding to 3'-untranslated region (3'-UTR). Ras-associated binding (Rab) proteins function as molecular switches for regulating vesicular transport, which mainly have oncogenic roles in cancer development and preventing the efficacy of chemotherapies. Increased evidence supported that miRNAs/Rabs interaction have been determined as potential therapeutics for cancer therapy. Nevertheless, instability and cross-targeting of miRNAs are main limitations of using miRNA-based therapeutic. The mutual interplay between Rabs and miRNAs has been poorly understood. In the present review, we focused on the essence and activity of these molecules in cancer pathogenesis. Also, numerous hindrances and potential methods in the expansion of miRNA as an anticancer therapeutics are mentioned.

Abstract
Long noncoding RNA taurine upregulated gene 1 (lncRNA TUG1) and microRNA‑196a (miR‑196a) have been reported to serve important roles in the development of renal cell carcinoma (RCC). However, their potential mechanisms have not been completely elucidated. The aim of the present study was to clarify the biological functions of lncRNA‑TUG1 and miR‑196a, in addition to investigating the interaction between lncRNA‑TUG1 and microRNA‑196a, providing a novel insight into RCC tumorigenesis. The present study comprised two parts. In the first part, lncRNA‑TUG1 was confirmed as an oncogene, via reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) analysis, MTT assay, flow cytometry analysis, and migration and invasion assays. In the second part, the association between lncRNA‑TUG1 and miR‑196a, and the molecular mechanism, was illustrated via RT‑qPCR analysis, MTT assay, dual luciferase reporter assay and western blotting. The results of the present study demonstrated that lncRNA‑TUG1 was able to promote RCC cell proliferation, migration and invasion in vitro by suppressing miR‑196a. Additionally, lncRNA‑TUG1 achieved its biological functions by regulating the expression levels of RAC‑α serine/threonine‑protein kinase, mitogen‑activated protein kinase and extracellular signal‑regulated kinase via inhibition of miR‑196a. In conclusion, the present findings proposed a novel potential therapeutic target, the lncRNA‑TUG1‑miR‑196a axis, which may be applicable to the treatment of RCC.

Abstract
Long intergenic non-coding RNA Linc00472 has been considered as a tumor suppressor in some cancers. However, the function and mechanism of Linc00472 in colorectal cancer has not been well elucidated. In this study, we found that Linc00472 was down-regulated in colorectal cancer tissues and cells. Elevated Linc00472 expression suppressed proliferation and induced apoptosis in colorectal cancer cells. Moreover, Linc00472 acted as a competing endogenous RNA (ceRNA) of miR-196a to release programmed cell death 4 (PDCD4). Furthermore, miR-196a overexpression or PDCD4 knockdown reversed Linc00472-mediated proliferation inhibition and apoptosis induction in colorectal cancer cells. Ectopic Linc00472 expression hindered tumor growth in vivo. Our study demonstrated that Linc00472 suppressed proliferation and induced apoptosis through up-regulating PDCD4 by decoying miR-196a, which may be an effective therapeutic target for colorectal cancer.

Abstract
Clear cell renal cell carcinoma (ccRCC) represents the most common kidney cancer worldwide. Increased cell proliferation associated with abnormal microRNA (miRNA) regulation are hallmarks of carcinogenesis. Ankyrin repeat and single KH domain 1 (ANKHD1) is a highly conserved protein found to interact with core cancer pathways in Drosophila; however, its involvement in RCC is completely unexplored. Quantitative PCR studies coupled with large-scale genomics data sets demonstrated that ANKHD1 is significantly up-regulated in kidneys of RCC patients when compared with healthy controls. Cell cycle analysis revealed that ANKHD1 is an essential factor for RCC cell division. To understand the molecular mechanism(s) utilized by ANKHD1 to drive proliferation, we performed bioinformatics analyses that revealed that ANKHD1 contains a putative miRNA-binding motif. We screened 48 miRNAs with tumor-enhancing or -suppressing activities and found that ANKHD1 binds to and regulates three tumor-suppressing miRNAs (i.e. miR-29a, miR-205, and miR-196a). RNA-immunoprecipitation assays demonstrated that ANKHD1 physically interacts with its target miRNAs via a single K-homology domain, located in the C terminus of the protein. Functionally, we discovered that ANKHD1 positively drives ccRCC cell mitosis via binding to and suppressing mainly miR-29a and to a lesser degree via miR-196a/205, leading to up-regulation in proliferative genes such as CCDN1. Collectively, these data identify ANKHD1 as a new regulator of ccRCC proliferation via specific miRNA interactions.

Abstract
MiR-196a could play important roles in carcinogenesis by targeting many protein coding genes. However, little is known about whether miR-196a can target any long non-coding RNAs (lncRNAs). In the present study, we screen lncRNAs which are regulated by miRNA-196a in human esophageal squamous cell carcinoma (ESCC). We found that miR-196a could suppress the expression of lncRNA growth arrest-specific 5(GAS5). GAS5 is frequently down-regulated in 86 paired human ESCC tissues. Importantly, there was lower GAS5 expression in the late stage of ESCC patients. The reduced expression of GAS5 in ESCC may not be related to DNA methylation but related to the high expression of miR-196a. In vitro and in vivo studies indicated that GAS5 could inhibit the growth of ESCC cells. Using Chromatin Isolation by RNA Purification-qPCR, we found that miR-196a could bind to GAS5. The Luciferase Reporter Assay indicated that miR-196a could bind to the seventh exon of GAS5. Additionally, both GAS5 and miR-196a could bind to Ago2 which is a key component of the RNA-induced silencing complex (RISC). Together, these results suggest that GAS5 functions as a tumor suppressor gene in ESCC and is regulated by miR-196a involved in RISC.

Abstract
MicroRNAs (miRNAs) have emerged as critical regulators in cancer progression. miR‑613 has been reported as a tumor suppressor gene in many types of human cancers. However, the function of miR‑613 in renal cell carcinoma (RCC) remains unclear. In the present study, the authors aimed to detect the expression of miR‑613 and its function in RCC cell lines. miR‑613 was reported to be significantly downregulated RCC cell lines. Functional analyses demonstrated that overexpression of miR‑613 significantly decreased RCC cell proliferation and invasion. Bioinformatics analysis showed that Frizzled7 (FZD7) was a predicted target of miR‑613, which was verified by dual‑luciferase reporter assay, reverse transcription quantitative‑polymerase chain reaction and western blot analysis. Restoration of FZD7 significantly reversed the suppressive effects of miR‑613 on RCC cell proliferation and invasion. Taken together, the results of the present study indicated that miR‑613 functions as a tumor suppressor that inhibits RCC cell proliferation and invasion by targeting and inhibiting FZD7, providing novel insight into RCC pathogenesis and a potential therapeutic target for RCC.

Abstract
The current study investigated the expression and functional roles of microRNA‑139 (miR‑139) on human epithelial ovarian cancer (EOC). Reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) was performed to measure miR‑139 expression in EOC tissues and cell lines. The effects of miR‑139 on EOC cell proliferation, migration and invasion were assessed using MTT, cell migration and invasion assays, respectively. Subsequently, the molecular mechanism underlying the tumor suppressive roles of miR‑139 on EOC was determined by bioinformatics analysis, RT‑qPCR, western blotting and the luciferase reporter assay. According to the results, it was identified that miR‑139 was significantly downregulated in EOC tissues and cell lines. In addition, restoration of miR‑139 suppressed tumor cell proliferation, migration and invasion in EOC. Furthermore, hepatoma‑derived growth factor (HDGF) was identified as a target of miR‑139 in EOC. Upregulation of HDGF could rescue the inhibitory effects exerted by miR‑139 overexpression on EOC cell proliferation, migration and invasion. Collectively, the results indicated that miR‑139 was downregulated in EOC, and acted as a tumor suppressor by directly targeting HDGF. To the best of our knowledge, this was the first study to identify that miR‑139 contributes to the growth and metastasis of EOC.

[PMID: 28662155 PMCID: PMC5491330 DOI: 10.1371/journal.pone.0180660] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2017] [Accepted: 06/19/2017] [Indexed: 12/21/2022] Open
Abstract
Accumulating evidence has demonstrated that some specific miRNAs were aberrantly expressed in renal clear cell carcinoma and participated in many biological processes. The aim of this study was to investigate a panel of miRNA signature for diagnosis and prognosis of renal clear cell carcinoma (KIRC). Here, we performed a comprehensive analysis for miRNA expression profiles and corresponding clinical information of 516 KIRC patients from The Cancer Genome Atlas (TCGA). In the study, a total of 63 differentially expressed miRNAs were identified, of which 34 were up-regulated and 29 were down-regulated. We constructed a panel of three-miRNA that were significantly associated with KIRC diagnosis and KIRC patients' prognosis. The three-miRNA signature reached a sensitivity of 98.3% and a specificity of 97.2% in the diagnosis of KIRC. Using the three-miRNA signature, we classified the KIRC patients into high-risk group and low-risk group. The Kaplan- Meier curves showed that KIRC patients with high risk scores had significantly worsen overall survival (OS) and disease free survival (DFS) than KIRC patients with low risk scores. In the univariate and multivariate Cox regression analysis, three-miRNA signature was an independent prognostic factor in OS. In conclusion, the three-miRNA signature could be used as a diagnostic and prognostic biomarker in KIRC, and therefore, may help to provide significant clinical implication for the treatment of KIRC.

Am J Cancer Res 2017; 7:2452-2462. [PMID: 28744327 PMCID: PMC5525749 DOI: 10.7150/thno.18813] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2016] [Accepted: 04/18/2017] [Indexed: 12/30/2022] Open
Abstract
MicroRNAs (miRNAs) play important roles in several neurobiological processes, including the development and progression of diseases. Previously, we identified that one specific miRNA, miR-196a, provides neuroprotective effects on Huntington's disease (HD), although the detailed mechanism is still unclear. Based on our bioinformatic analyses, we hypothesize miR-196a might offer neuroprotective functions through improving cytoskeletons of brain cells. Here, we show that miR-196a could enhance neuronal morphology, further ameliorating intracellular transport, synaptic plasticity, neuronal activity, and learning and memory abilities. Additionally, we found that miR-196a could suppress the expression of RAN binding protein 10 (RANBP10) through binding to its 3' untranslated region, and higher expression of RANBP10 exacerbates neuronal morphology and intracellular transport. Furthermore, miR-196a enhances neuronal morphology through suppressing RANBP10 and increasing the ability of β-tubulin polymerization. Most importantly, we observed higher expression of RANBP10 in the brains of HD transgenic mice, and higher expression of RANBP10 might exacerbate the pathological aggregates in HD. Taken together, we provide evidence that enhancement of neuronal morphology through RANBP10 is one of the neuroprotective mechanisms for miR-196a. Since miR-196a has also been reported in other neuronal diseases, this study might offer insights with regard to the therapeutic use of miR-196a in other neuronal diseases.

Abstract
Altered microRNA (miRNA) expression has been reported to participate in the pathogenesis of several human diseases, and particularly cancer. The present study examined the involvement of various miRNAs in the pathophysiology of endometrial cancer (EC) and atypical endometrial hyperplasia (AEH). We performed a high-throughput analysis of the miRNAs (miRNA microarray) found in samples of endometrial tissue obtained from 45 patients; among whom, 15 patients were diagnosed with EC, 15 patients were diagnosed with AEH, and the remainder were healthy donors. Next, we selected several miRNAs which exhibited at least a 2-fold difference in expression with a P<0.05 to validate these changes in 3 independent in vitro experiments that used real-time PCR analysis. Finally, miR-1202 and miR-196a were selected as target molecules whose effects on cell apoptosis, cell cycle changes, cell migratory and invasive abilities were investigated using flow cytometric and Transwell assays, respectively, after pre-treatment in vitro. After analyzing 125 miRNAs in a microarray assay, 6 miRNAs (3-high and 3-low expression) were further evaluated via paired comparison in all 3 groups. The validation test revealed a positive correlation between the microarray results and a high level of miR-1202 and a low level of miR-196a in the EC group, when compared with the AEH group. All of the data were normalized with data obtained from normal control donors. We found that either miR-1202 silencing or miR-196a overexpression affected AN3CA and HEC-1-A cells by increasing their apoptosis level and inducing G1 phase arrest while decreasing their migratory and invasive abilities. Inhibitors of miR-1202 and mimics of miR‑196a may exert a protective effect, suggesting that miR-1202 and miR‑196a may serve as biomarkers for evaluating the effectiveness of EC treatment.

Abstract
BACKGROUND Understanding the roles of circulating microRNAs (miRNAs) can provide important and novel information regarding disease pathogenesis and a patient's clinical condition. Circulating miRNAs, such as exosomal miRNA, may regulate various bioactivities related to intercellular communication. However, the circulation of miRNAs in Graves' disease (GD) in relation to disease activity has never been elucidated. This study aimed to identify circulating miRNAs in GD in relation to disease activity and whether their exosomes play a role in the pathogenesis of GD. METHODS Circulating miRNAs were measured in serum obtained from seven intractable GD patients, seven GD patients in remission, and seven healthy controls using the miScript miRNA PCR Array. Altered miRNAs selected from array data were validated in 65 subjects. To investigate exosome biology, peripheral blood mononuclear cells (PBMCs) were incubated with exosomes isolated from the subjects' sera. mRNAs were quantified for cytokines using quantitative real-time polymerase chain reaction. RESULTS Circulating miR-23b-5p and miR-92a-39 were increased in GD patients in remission compared with intractable GD patients (p < 0.05). On the other hand, let-7g-3p and miR-339-5p were decreased in GD patients in remission compared with intractable GD patients (p < 0.05). Exosomes from intractable GD patients stimulated mRNA expression for IL-1β and TNF-α compared with GD patients in remission or healthy controls. CONCLUSIONS This study demonstrates that different levels of circulating miRNAs are associated with intractable GD. Moreover, serum exosomes of patients with intractable GD may activate immune cells, which may play an important role in GD pathogenesis.
