Abstract
Psoriasis is a chronic inflammatory skin disease with keratinocyte hyperproliferation and T cells as key mediators of lesional and systemic inflammatory changes. To date, no suitable differential biomarkers are available for the disease diagnosis. More recently, microRNAs have been identified as critical regulators of lesional and systemic immune changes in psoriasis with diagnostic potential. We have performed expression profiling of T cell-specific miRNAs in 38 plasma samples from psoriasis vulgaris patients and an equal number of age- and gender-matched healthy subjects. Our findings have identified a panel of five blood-based circulatory miRNAs with a significant change in their expression levels, comprising miR-215, miR-148a, miR-125b-5p, miR-223, and miR-142-3p, which can differentiate psoriasis vulgaris patients from healthy individuals. The receiver operating characteristic (ROC) curves for all five miRNAs individually and in combination exhibited a significant disease discriminatory area under the curve with an AUC of 0.762 and a p < 0.0001 for all the miRNAs together. Statistically, all five miRNAs in combination depicted the best-fit model in relation to disease severity (PASI) compared with individual miRNAs, with the highest R2 value of 0.94 and the lowest AIC score of 131.8. Each of the miRNAs also exhibited a significant association with at least one of the other miRNAs in the panel. Importantly, the five miRNAs in the panel regulate one or more immune-inflammation pathways based on target prediction, pathway network analysis, and validated roles in the literature. The miRNA panel provides a rationalized combination of biomarkers that can be tested further on an expanded cohort of patients for their diagnostic value.

Abstract
BACKGROUND DNA hypermethylation is an epigenetic feature that modulates gene expression, and its deregulation is observed in cancer. Previously, we identified a neural-related DNA hypermethylation fingerprint in colon cancer, where most of the top hypermethylated and downregulated genes have known functions in the nervous system. To evaluate the presence of this signature and its relevance to carcinogenesis in general, we considered 16 solid cancer types available in The Cancer Genome Atlas (TCGA). RESULTS All tested cancers showed significant enrichment for neural-related genes amongst hypermethylated genes. This signature was already present in two premalignant tissue types and could not be explained by potential confounders such as bivalency status or tumor purity. Further characterization of the neural-related DNA hypermethylation signature in colon cancer showed particular enrichment for genes that are overexpressed during neural differentiation. Lastly, an analysis of upstream regulators identified RE1-Silencing Transcription factor (REST) as a potential mediator of this DNA methylation signature. CONCLUSION Our study confirms the presence of a neural-related DNA hypermethylation fingerprint in various cancers, of genes linked to neural differentiation, and points to REST as a possible regulator of this mechanism. We propose that this fingerprint indicates an involvement of DNA hypermethylation in the preservation of neural stemness in cancer cells.

Abstract
BACKGROUND Despite major advances in the treatment of diabetic nephropathy (DN) in recent years, it remains the most common cause of end-stage renal disease. An early diagnosis and therapy may slow down the DN progression. Numerous potential biomarkers are currently being researched. Circulating levels of the kidney-released exosomes and biological molecules, which reflect the DN pathology including glomerular and tubular dysfunction as well as mesangial expansion and fibrosis, have shown the potential for predicting the occurrence and progression of DN. Moreover, many experimental therapies are currently being investigated, including stem cell therapy and medications targeting inflammatory, oxidant, or pro-fibrotic pathways activated during the DN progression. The therapeutic potential of stem cells is partly depending on their secretory capacity, particularly exosomal microRNAs (Exo-miRs). In recent years, a growing line of research has shown the participation of Exo-miRs in the pathophysiological processes of DN, which may provide effective therapeutic and biomarker tools for DN treatment. METHODS A systematic literature search was performed in MEDLINE, Scopus, and Google Scholar to collect published findings regarding therapeutic stem cell-derived Exo-miRs for DN treatment as well as circulating Exo-miRs as potential DN-associated biomarkers. FINDINGS Glomerular mesangial cells and podocytes are the most important culprits in the pathogenesis of DN and, thus, can be considered valuable therapeutic targets. Preclinical investigations have shown that stem cell-derived exosomes can exert beneficial effects in DN by transferring renoprotective miRs to the injured mesangial cells and podocytes. Of note, renoprotective Exo-miR-125a secreted by adipose-derived mesenchymal stem cells can improve the injured mesangial cells, while renoprotective Exo-miRs secreted by adipose-derived stem cells (Exo-miR-486 and Exo-miR-215-5p), human urine-derived stem cells (Exo-miR-16-5p), and bone marrow-derived mesenchymal stem cells (Exo-miR-let-7a) can improve the injured podocytes. On the other hand, clinical investigations have indicated that circulating Exo-miRs isolated from urine or serum hold great potential as promising biomarkers in DN.

[PMID: 34781085 PMCID: PMC8605108 DOI: 10.1016/j.neo.2021.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Accepted: 11/04/2021] [Indexed: 11/09/2022] Open
Abstract
Background: The acidic extracellular environment of tumors has been shown to affect the malignant progression of tumor cells by modulating proliferation, cell death or metastatic potential. The aim of the study was to analyze whether acidosis-dependent miRNAs play a role in the signaling cascade from low pH through changes in gene expression to functional properties of tumors in vitro and in vivo. Methods: In two experimental tumor lines the expression of 13 genes was tested under acidic conditions in combination with overexpression or downregulation of 4 pH-sensitive miRNAs (miR-7, 183, 203, 215). Additionally, the impact on proliferation, cell cycle distribution, apoptosis, necrosis, migration and cell adhesion were measured. Results: Most of the genes showed a pH-dependent expression, but only a few of them were additionally regulated by miRNAs in vitro (Brip1, Clspn, Rif1) or in vivo (Fstl, Tlr5, Txnip). Especially miR-215 overexpression was able to counteract the acidosis effect in some genes. The impact on proliferation was cell line-dependent and most pronounced with overexpression of miR-183 and miR-203, whereas apoptosis and necrosis were pH-dependent but not influenced by miRNAs. The tumor growth was markedly regulated by miR-183 and miR-7. In addition, acidosis had a strong effect on cell adhesion, which could be modulated by miR-7, miR-203 and miR-215. Conclusions: The results indicate that the acidosis effect on gene expression and functional properties of tumor cells could be mediated by pH-dependent miRNAs. Many effects were cell line dependent and therefore do not reflect universal intracellular signaling cascades. However, the role of miRNAs in the adaptation to an acidic environment may open new therapeutic strategies.

Abstract
Severe acute respiratory syndrome (SARS) is a highly contagious viral respiratory illness. This illness is spurred on by a coronavirus known as SARS-associated coronavirus (SARS-CoV). SARS was first detected in Asia in late February 2003. The genome of this virus is very similar to the SARS-CoV-2. Therefore, the study of SARS-CoV disease and the identification of effective drugs to treat this disease can be new clues for the treatment of SARS-Cov-2. This study aimed to discover novel potential drugs for SARS-CoV disease in order to treating SARS-Cov-2 disease based on a novel systems biology approach. To this end, gene co-expression network analysis was applied. First, the gene co-expression network was reconstructed for 1441 genes, and then two gene modules were discovered as significant modules. Next, a list of miRNAs and transcription factors that target gene co-expression modules' genes were gathered from the valid databases, and two sub-networks formed of transcription factors and miRNAs were established. Afterward, the list of the drugs targeting obtained sub-networks' genes was retrieved from the DGIDb database, and two drug-gene and drug-TF interaction networks were reconstructed. Finally, after conducting different network analyses, we proposed five drugs, including FLUOROURACIL, CISPLATIN, SIROLIMUS, CYCLOPHOSPHAMIDE, and METHYLDOPA, as candidate drugs for SARS-CoV-2 coronavirus treatment. Moreover, ten miRNAs including miR-193b, miR-192, miR-215, miR-34a, miR-16, miR-16, miR-92a, miR-30a, miR-7, and miR-26b were found to be significant miRNAs in treating SARS-CoV-2 coronavirus.

Abstract
Objective The objectives of this review are to discuss: the definition, clinical and biologic features of oligometastatic non-small cell lung cancer (NSCLC), as well as the concept of treating oligoprogression in oligometastatic NSCLC. Background A substantial proportion of patients diagnosed with lung cancer present with metastatic disease, and a large portion of patients who present with localized disease later develop metastases. Oligometastatic NSCLC is defined as an intermediate state between localized and widespread metastatic disease, where there may be a role for curative localized therapy approach by treating the primary tumor and all metastases with radiotherapy or surgery. Despite the increasing application of this approach in patients with lung cancer, the identification of patients who might benefit from this approach is yet to be well characterized. Methods After a systematic review of the literature, a PubMed search was performed using the English language and the key terms: oligometastatic, non-small cell lung cancer (NSCLC), localized consolidative treatment (LCT), biomarkers, biologic features, clinical features. Over 500 articles were retrieved between 1889–2021. A total of 178 papers discussing the definition, clinical and biologic factors leading to oligometastatic NSCLC were reviewed and included in the discussion of this paper. Conclusions Oligometastatic NSCLC is a unique entity. Identifying patients who have oligometastatic NSCLC accurately using a combination of clinical and biologic features and treating them with localized consolidative approach appropriately results in improvement of outcome. Further understanding of the molecular mechanisms driving the formation of oligometastatic NSCLC is an important area of focus for future studies.

Abstract
Objective: Wilm’s tumor is a common renal malignancy in childhood with unsatisfactory prognosis. microRNA-215-5p (miR-215-5p) has been reported as a tumor-suppressive miRNA in different types of human cancers, but rarely in the Wilm’s tumor. In light of this, we tried to investigate the regulatory role and underlying mechanism of miR-215-5p in the Wilm’s tumor. Methods: After sample collection and cell culture, the expression of miR-215-5p and CT10 Regulator of Kinase (CRK) was detected. Then rhabdoid tumor cell lines (formerly classified as Wilms’ tumor cell lines), G401 and WT-CLS1 cells were transfected with pcDNA3.1, pcDNA3.1-CRK, sh-NC, sh-CRK, agomir NC, miR-215-5p agomir, antagomir NC or miR-215-5p antagomir to explore the function of miR-215-5p and CRK in the Wilm’s tumor cell proliferation and migration. Moreover, the relationship between miR-215-5p and CRK was analyzed by dual luciferase reporter gene assay. Results: Lowly-expressed miR-215-5p and highly-expressed CRK were observed in the Wilm’s tumor tissues and cells. Transfection of pcDNA3.1-CRK or miR-215-5p antagomir could promote G401 and WT-CLS1 cell proliferation and enhance migration ability, while transfection of sh-CRK or miR-215-5p agomir led to opposite results. Additionally, miR-215-5p may bind to CRK. Moreover, transfection of pcDNA3.1-CRK in G401 and WT-CLS1 cells could partially reverse the inhibitory effect of miR-215-5p agomir on the proliferation and migration of Wilm’s tumor cells. Conclusion: Our study highlighted that miR-215-5p could suppress the proliferation and migration of Wilm’s tumor cells by regulating the expression of CRK, providing new ideas for molecular targeted therapy for Wilm’s tumor.

Abstract
ABSTRACT Doxorubicin (DOX) is a chemotherapeutic drug for treating various cancers. However, the DOX-induced cardiotoxicity greatly limits its clinical application. MicroRNAs (miRNAs) are emerged as critical mediators of cardiomyocyte injury. This work explored the function of miR-215-5p in the regulation of DOX-induced mouse HL-1 cardiomyocyte injury. An in vitro model of DOX-treated cardiotoxicity was established in HL-1 cells. Gene expression was measured by RT-qPCR. Cell viability was detected using CCK-8. Cell death and apoptosis were tested using TUNEL, flow cytometry, and caspase 3/7 activity assays. Luciferase reporter assay was used to examine the target of miR-215-5p. We found that DOX induced cardiomyocyte injury and upregulated miR-215-5p in HL-1 cells. Inhibition of miR-215-5p attenuated DOX-induced cardiomyocyte death and apoptosis in vitro. Mechanistical experiments indicated that ZEB2 was targeted by miR-215-5p. Additionally, ZEB2 expression was reduced in DOX-treated HL-1 cells. Rescue assays indicated that ZEB2 knockdown reversed the effects of miR-215-5p inhibition. In conclusion, miR-215-5p inhibition protects HL-1 cells against DOX-induced injury by upregulating ZEB2 expression.

Abstract
Mus musculus is the most commonly used animal model in microRNA research; however, little is known about the endogenous miRNome of the animals used in the miRNA-targeting preclinical studies with the human xenografts. In the presented study, we evaluated the NOD/SCID gamma mouse model for the preclinical study of systemic miR-215-5p substitution with a semitelechelic poly[N-(2-hydroxypropyl)-methacrylamide]-based carrier conjugated with miR-215-5p-mimic via a reductively degradable disulfide bond. Murine mmu-miR-215-5p and human hsa-miR-215-5p have a high homology of mature sequences with only one nucleotide substitution. Due to the high homology of hsa-miR-215-5p and mmu-hsa-miR-215-5p, a similar expression in human and NOD/SCID gamma mice was expected. Expression of mmu-miR-215 in murine organs did not indicate tissue-specific expression and was highly expressed in all examined tissues. All animals included in the study showed a significantly higher concentration of miR-215-5p in the blood plasma compared to human blood plasma, where miR-215-5p is on the verge of a reliable detection limit. However, circulating mmu-miR-215-5p did not enter the human xenograft tumors generated with colorectal cancer cell lines since the levels of miR-215-5p in control tumors remained notably lower compared to those originally transfected with miR-215-5p. Finally, the systemic administration of polymer-miR-215-5p-mimic conjugate to the tail vein did not increase miR-215-5p in NOD/SCID gamma mouse blood plasma, organs, and subcutaneous tumors. It was impossible to distinguish hsa-miR-215-5p and mmu-miR-215-5p in the murine blood and organs due to the high expression of endogenous mmu-miR-215-5p. In conclusion, the examination of endogenous tissue and circulating miRNome of an experimental animal model of choice might be necessary for future miRNA studies focused on the systemic delivery of miRNA-based drugs conducted in the animal models.

Abstract
OBJECTIVES Extracellular vesicle microRNAs (EV-miRNAs) have been demonstrated to be reliable candidate biomarkers for clinical applications. However, the clinical application potential of serum EV-miR-215-5p for gastric cancer (GC) remains poorly understood. The goal of our study was to determine the efficacy of serum EV-miR-215-5p in predicting the prognosis of GC. METHODS Blood samples were collected from 118 patients with GC, 60 patients with benign gastric disease and BGD and 70 healthy controls. The relative levels of serum EV-miR-215-5p were measured using quantitative real-time polymerase chain reaction (qRT-PCR). RESULTS Compared to patients with BGD and normal controls, GC patients exhibited remarkably higher serum EV-miR-215-5p level, especially those with early tumor recurrence (ETR). Receiver operating characteristic (ROC) curve analysis showed that serum EV-miR-215-5p was able to distinguish GC patients from BGD patients or healthy controls and GC patients with ETR from those without ETR. In addition, increased serum EV-miR-215-5p levels were notably correlated with invasive depth, TNM stage, and lymph node metastasis. Moreover, serum EV-miR-215-5p levels were greatly decreased after surgical treatment, but increased at the time of ETR. Survival analysis showed that patients with higher serum EV-miR-215-5p had shorter survival. Furthermore, serum EV-miR-215-5p was an independent risk factor for GC. CONCLUSIONS Serum EV-miR-215-5p might be a novel biomarker for predicting ETR and prognosis of GC.

MiR-215-5p Reduces Liver Metastasis in an Experimental Model of Colorectal Cancer through Regulation of ECM-Receptor Interactions and Focal Adhesion. Cancers (Basel) 2020; 12:cancers12123518. [PMID: 33255928 PMCID: PMC7760708 DOI: 10.3390/cancers12123518] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Accepted: 11/23/2020] [Indexed: 12/11/2022] Open
Abstract
Simple Summary Decreased expression of miR-215-5-p was found in tumor tissue of patients with colorectal cancer (CRC) in comparison to healthy colon tissue. Moreover, expression levels of miR-215-5p were further decreased in metastatic lesions compared to primary tumor tissue. Overall, CRC patients with lower expression of miR-215-5p in tumors had significantly shorter overall survival and a higher chance of metastasis. This study aimed to examine the effects of miR-215-5p supplementation on the metastatic potential of CRC. MiR-215-5p was found to decrease invasiveness, migratory capacity, tumorigenicity, and metastasis formation. Finally, transcriptome analysis identified signaling pathways involved in the process, and subsequent RT-qPCR validation indicates CTNNBIP1 to be a direct target of this microRNA. These results bring new insight into miR-215-5p biology, a molecule that could potentially serve as a promising target for CRC patients’ future therapeutic strategies. Abstract Background: Growing evidence suggests that miR-215-5p is a tumor suppressor in colorectal cancer (CRC); however, its role in metastasis remains unclear. This study evaluates the effects of miR-215 overexpression on the metastatic potential of CRC. Methods: CRC cell lines were stably transfected with miR-215-5p and used for in vitro and in vivo functional analyses. Next-generation sequencing and RT-qPCR were performed to study changes on the mRNA level. Results: Overexpression of miR-215-5p significantly reduced the clonogenic potential, migration, and invasiveness of CRC cells in vitro and tumor weight and volume, and liver metastasis in vivo. Transcriptome analysis revealed mRNAs regulated by miR-215-5p and RT-qPCR confirmed results for seven selected genes. Significantly elevated levels of CTNNBIP1 were also observed in patients’ primary tumors and liver metastases compared to adjacent tissues, indicating its direct regulation by miR-215-5p. Gene Ontology and KEGG pathway analysis identified cellular processes and pathways associated with miR-215-5p deregulation. Conclusions: MiR-215-5p suppresses the metastatic potential of CRC cells through the regulation of divergent molecular pathways, including extracellular-matrix-receptor interaction and focal adhesion. Although the specific targets of miR-215-5p contributing to the formation of distant metastases must be further elucidated, this miRNA could serve as a promising target for CRC patients’ future therapeutic strategies.

Uddin MN, Wang X. The landscape of long non-coding RNAs in tumor stroma. Life Sci 2020; 264:118725. [PMID: 33166593 DOI: 10.1016/j.lfs.2020.118725] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Revised: 10/26/2020] [Accepted: 11/03/2020] [Indexed: 02/06/2023]
Abstract
AIMS Long non-coding RNAs (lncRNAs) are associated with cancer development, while their relationship with the cancer-associated stromal components remains poorly understood. In this review, we performed a broad description of the functional landscape of stroma-associated lncRNAs in various cancers and their roles in regulating the tumor-stroma crosstalk. MATERIALS AND METHODS We carried out a systematic literature review of PubMed, Scopus, Medline, Bentham, and EMBASE (Elsevier) databases by using the keywords "LncRNAs in cancer," "LncRNAs in tumor stroma," "stroma," "cancer-associated stroma," "stroma in the tumor microenvironment," "tumor-stroma crosstalk," "drug resistance of stroma," and "stroma in immunosuppression" till July 2020. We collected the latest articles addressing the biological functions of stroma-associated lncRNAs in cancer. KEY FINDINGS These articles reported that dysregulated stroma-associated lncRNAs play significant roles in modulating the tumor microenvironment (TME) by the regulation of tumor-stroma crosstalk, epithelial to mesenchymal transition (EMT), endothelial to mesenchymal transition (EndMT), extracellular matrix (ECM) turnover, and tumor immunity. SIGNIFICANCE The tumor stroma is a substantial portion of the TME, and the dysregulation of tumor stroma-associated lncRNAs significantly contributes to cancer initiation, progression, angiogenesis, immune evasion, metastasis, and drug resistance. Thus, stroma-associated lncRNAs could be potentially useful targets for cancer therapy.

Abstract
Molecular signaling pathways involved in cancer have been intensively studied due to their crucial role in cancer cell growth and dissemination. Among them, zinc finger E-box binding homeobox-1 (ZEB1) and -2 (ZEB2) are molecules that play vital roles in signaling pathways to ensure the survival of tumor cells, particularly through enhancing cell proliferation, promoting cell migration and invasion, and triggering drug resistance. Importantly, ZEB proteins are regulated by microRNAs (miRs). In this review, we demonstrate the impact that miRs have on cancer therapy, through their targeting of ZEB proteins. MiRs are able to act as onco-suppressor factors and inhibit the malignancy of tumor cells through ZEB1/2 down-regulation. This can lead to an inhibition of epithelial-mesenchymal transition (EMT) mechanism, therefore reducing metastasis. Additionally, miRs are able to inhibit ZEB1/2-mediated drug resistance and immunosuppression. Additionally, we explore the upstream modulators of miRs such as long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs), as these regulators can influence the inhibitory effect of miRs on ZEB proteins and cancer progression.

Abstract
BACKGROUND This study was aimed at exploring the effects of miR-215 and its target gene stearoyl-CoA desaturase (SCD) on colorectal cancer (CRC) cell migration and invasion. METHODS Here, we analyzed the relationship between miR-215 and SCD, as well as the regulation of miR-215 on CRC cells. We constructed wild-type and mutant plasmids of SCD to identify whether SCD was a target gene of miR-215 by using a luciferase reporter assay. The expression of miR-215 and SCD was detected by quantitative real-time polymerase chain reaction (qRT-PCR) and western blot, respectively. MTT, wound healing, and Transwell assays were applied to determine the effect of miR-215 on CRC cell proliferation, migration, and invasion. RESULTS It was found that miR-215 expression was significantly decreased in CRC tissue while SCD was highly expressed compared with those in adjacent normal tissue. The luciferase reporter assay indicated that SCD was a direct target gene of miR-215. Functional analysis revealed that miR-215 overexpression significantly inhibited CRC cell proliferation, migration, and invasion in vitro. In addition, the result of rescue experiments showed that overexpression of SCD could promote the proliferation, migration, and invasion of CRC cells, and the carcinogenic effect of SCD could be inhibited by miR-215. CONCLUSIONS Taken together, our findings suggested that miR-215 could inhibit CRC cell migration and invasion via targeting SCD. The result could eventually contribute to the treatment for CRC.

Exosomal miRNA-215-5p Derived from Adipose-Derived Stem Cells Attenuates Epithelial-Mesenchymal Transition of Podocytes by Inhibiting ZEB2. BIOMED RESEARCH INTERNATIONAL 2020; 2020:2685305. [PMID: 32149094 PMCID: PMC7057016 DOI: 10.1155/2020/2685305] [Citation(s) in RCA: 56] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Accepted: 12/31/2019] [Indexed: 02/06/2023]
Abstract
Background Podocyte migration is actively involved in the process of podocyte loss and proteinuria production, which is closely associated with the development of diabetic nephropathy (DN). Exosomes from adipose-derived stem cells (ADSCs-Exos) effectively inhibit podocyte apoptosis in the treatment of DN. However, how ADSCs-Exos affect the migration of podocytes is obscure. This study is aimed at exploring the regulatory role of ADSCs-Exos on cell migration and the underlying mechanism. Methods ADSCs-Exo was authenticated by transmission electron microscopy (TEM), western blotting, and flow cytometry. Cell viability and migration ability of podocytes were measured by CCK8 and Transwell assays, respectively. Relative expressions of miRNAs and mRNAs were determined by qRT-PCR. The transmitting between PKH26-labeled exosome and podocytes was evaluated by IF assay. Dual luciferase reporter assay was employed to detect the relationship between miR-215-5p and ZEB2. Results The exposure to serum from DN patient (hDN-serum) significantly inhibited cell viability of podocytes, but ADSCs-Exo addition notably blunts cytotoxicity induced by the transient stimulus of hDN-serum. Besides, ADSCs-Exo administration powerfully impeded high glucose- (HG-) induced migration and injury of podocyte. With the podocyte dysfunction, several miRNAs presented a significant decline under the treatment of HG including miR-251-5p, miR-879-5p, miR-3066-5p, and miR-7a-5p, all of which were rescued by the addition of ADSCs-Exo. However, only miR-251-5p was a key determinant in the process of ADSCs-Exo-mediated protective role on podocyte damage. The miR-251-5p inhibitor counteracted the improvement from the ADSCs-Exo preparation on HG-induced proliferation inhibition and migration promotion. Additionally, miR-215-5p mimics alone remarkably reversed HG-induced EMT process of podocyte. Mechanistically, we confirmed that ADSCs-Exos mediated the shuttling of miR-215-5p to podocyte, thereby protecting against HG-induced metastasis, possibly through inhibiting the transcription of ZEB2. Conclusion ADSCs-Exo has the protective effect on HG-evoked EMT progression of podocytes thru a mechanism involving ZEB2. Potentially, the ADSCs-Exo preparation is a useful therapeutic strategy for improving podocyte dysfunction and DN symptoms clinically.

Abstract
Metastasis, the development of secondary malignant growths at a distance from the primary site of a cancer, is associated with almost 90% of all cancer deaths, and half of all cancer patients present with some form of metastasis at the time of diagnosis. Consequently, there is a clear clinical need for a better understanding of metastasis. The role of miRNAs in the metastatic process is beginning to be explored. However, much is still to be understood. In this review, we present the accumulating evidence for the importance of miRNAs in metastasis as key regulators of this hallmark of cancer.

Abstract
The main causes of death among patients with hepatocellular carcinoma (HCC) are a recurrence, metastasis, and deterioration of primary tumors by the epithelial-to-mesenchymal transition (EMT) which is controlled by several molecules including E-cadherin and N-cadherin. Microribonucleic acids (miRNAs) have been identified to play a regulatory role in EMT. miR-215 is important in repressing migration/invasion of cancer cells. In this study, we aimed to evaluate the crosstalk between miR-215 and EMT specific markers (E-cadherin and N-cadherin) with a spotlight on its role in the EMT process in hepatitis C virus (HCV)-infected patients. One hundred forty-five patients were studied, 75 had HCV-induced cirrhosis classified into child A, B, and C and 25 had HCC. In parallel, 45 healthy volunteers considered as controls. Serum levels of E- and N-cadherin were measured using enzyme-linked immunosorbent assay and miR-215 expression measured by a quantitative reverse transcription-polymerase chain reaction. Insignificant change in serum levels of E-cadherin and N-cadherin in HCV-infected patients compared with normal controls was observed with a slight increase in E-cadherin and N-cadherin in the child B group. HCC patients had the lowest amount of E-cadherin and N-cadherin compared with cirrhotic and normal subjects. A maximum reduction in miR-215 was observed in HCC patients compared with cirrhotic and control ones. A positive correlation (r = .202; P < .05) was observed between miR-215 and E-cadherin. Our data stressed on the potential role of miR-215 as an important mediator in HCC progression. miRNAs participating in EMT needs further studies to provide insight into the metastasis of HCC.

Abstract
Several studies have shown that miR-215-5p acts as a tumor suppressor in certain cancers, but its role in the progression and metastasis of breast carcinoma remains incompletely understood. Herein, we prove that miR-215-5p is substantially down-expressed in breast carcinoma as compared with nontumor tissue. Up-regulation of miR-215-5p inhibits the aggressive abilities of breast carcinoma cells in vitro. We performed luciferase reporter tests to show that SRY-Box 9 (Sox9) is the target of miR-215-5p; as predicted, Sox9 depletion replicates the suppressive effects of miR-215-5p on breast carcinoma cells, and overexpression of Sox9 rescues the effects of miR-215-5p on breast cancer cell progression. In addition, a xenograft model assay was used to reveal that miR-215-5p inhibits breast cancer cell growth and metastatic potential in vivo. Overall, these results imply that miRNA-215-5p suppresses the aggressiveness of breast cancer cells through targeting Sox9.

Abstract
Breast cancer (BC) is one of the most common cancers in females. Since early detection can bring prognosis benefit, discovery of novel noninvasive biomarkers for BC diagnosis is in urgent need. In this four‐phase study, we profiled miRNA expression in plasma samples from a total of 257 BC patients and 257 normal controls (NCs). Exiqon miRNA qPCR panel was used to select candidate miRNAs in the screening phase which were further analyzed using qRT‐PCR in the following training, testing and external validation phases. Finally, we identified five plasma miRNAs (let‐7b‐5p, miR‐122‐5p, miR‐146b‐5p, miR‐210‐3p and miR‐215‐5p) whose expression levels were significantly different between BC patients and NCs. A 5‐miRNA panel in plasma with high sensitivity and specificity was then constructed to detect BC. The areas under the receiver‐operating characteristic curves (AUCs) of the panel were 0.683, 0.966, 0.978 for the training, testing and external validation sets, respectively. Expression of the identified miRNAs was further analyzed among 32 pairs of BC tissue and the adjacent normal tissue samples as well as plasma‐derived exosome samples from 32 BC patients vs 32 NCs. Let‐7b‐5p was contrarily down‐regulated in BC tissue. In exosomes samples, only miR‐122‐5p was significantly up‐regulated as in plasma for BC patients. In conclusion, we identified a 5‐miRNA plasma panel (let‐7b‐5p, miR‐122‐5p, miR‐146b‐5p, miR‐210‐3p and miR‐215‐5p) that could serve as a promising biomarker for BC detection.

Abstract
Zinc finger E-box binding homeobox 2 (ZEB2) is a DNA-binding transcription factor, which is mainly involved in epithelial-to-mesenchymal transition (EMT). EMT is a conserved process during which mature and adherent epithelial-like state is converted into a mobile mesenchymal state. Emerging data indicate that ZEB2 plays a pivotal role in EMT-induced processes such as development, differentiation, and malignant mechanisms, for example, drug resistance, cancer stem cell-like traits, apoptosis, survival, cell cycle arrest, tumor recurrence, and metastasis. In this regard, the understanding of mentioned subjects in the development of normal and cancerous cells could be helpful in cancer complexity of diagnosis and therapy. In this study, we review recent findings about the biological properties of ZEB2 in healthy and cancerous states to find new approaches for cancer treatment.

[PMID: 31297882 DOI: 10.1002/jcb.29197] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Revised: 05/31/2019] [Accepted: 05/31/2019] [Indexed: 01/01/2023]
Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in the world. Nevertheless, its underlying molecular mechanisms are largely unknown. LINC00152 are recently investigated in several cancer types. In our current investigation, we observed LINC00152 was obviously upregulated in HCC cells. LINC00152 was significantly downregulated by infecting LV-shLINC00152 in HepG2 and SNU449 cells. Loss of LINC00152 remarkably repressed HCC cell proliferation, cell colony formation, induced cell apoptosis, and restrained cell migration/invasion. Growing evidence has reported long noncoding RNAs can sponge microRNAs to modulate cancer process. Here, we indicated miR-215 was greatly decreased in HCC and LINC00152 regulated HCC development via sponging miR-215. For another, the binding association between LINC00152 and miR-215 was proved by a series of functional assays. CDK13 was predicted as the target of miR-215. Upregulation of miR-215 greatly depressed CDK13 in HCC cells. Subsequently, the in vivo results demonstrated that silence of LINC00152 restrained HCC development via modulating miR-215 to up-regulate CDK13. Therefore, it was revealed that LINC00152 contributed to the progression of HCC by the modulation of miR-215 and CDK13.

Treatment with somatostatin analogs induces differentially expressed let-7c-5p and mir-3137 in small intestine neuroendocrine tumors. BMC Cancer 2019; 19:575. [PMID: 31196127 PMCID: PMC6567424 DOI: 10.1186/s12885-019-5794-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2018] [Accepted: 06/05/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Distant metastases frequently occur in gastroenteropancreatic neuroendocrine tumors. If hepatic surgery is not feasible, patients are treated with somatostatin analogs. However, the underlying mechanisms of action of this treatment remain to be defined. The aim of the present study was to analyze the micro-RNA expression profile inter-individually before and after the treatment with somatostatin analogs. MATERIAL AND METHODS Tumor specimens of all included patients (n = 8) before and after the onset of a therapy with somatostatin analogs were analyzed and a micro-RNA expression profile (754 micro-RNAs) of each probe was generated. This analysis in an intra-individual setting was selected to avoid bias from inter-individual differences. The micro-RNA expression profiles were validated by qPCR. Patients with any other systemic treatment were excluded from the present study. RESULTS Eight patients were included in the present study of which all had neuroendocrine tumors of the small intestine with diffuse hepatic metastases. Grouped analyses revealed that 15 micro-RNAs were differentially expressed (3 up- and 12 downregulated) after the exposure to somatostatin analogs. Additionally, let-7c-5p and mir-3137 are concordantly regulated in the inter-individually analysis. CONCLUSIONS This is the first study analyzing the individual micro-RNA expression profile before and after a therapy with somatostatin analogs. Data from this study reveal that somatostatin analogs may in part exert their beneficial effects through an alteration in the micro-RNA expression profile.

Abstract
MicroRNAs have emerged as key regulators involved in a variety of biological processes. Previous studies have demonstrated that miR-192/215 participated in progression of Crohn's disease and colorectal cancer. However, their concrete relationships and regulation networks in diseases remain unclear. Here, we used bioinformatics methods to expound miR-192/215-5p macrocontrol regulatory networks shared by two diseases. For data mining and figure generation, several miRNA prediction tools, Human miRNA tissue atlas, FunRich, miRcancer, MalaCards, STRING, GEPIA, cBioPortal, GEO databases, Pathvisio, Graphpad Prism 6 software, etc . are extensively applied. miR-192/215-5p were specially distributed in colon tissues and enriched biological pathways were closely associated with human cancers. Emerging role of miR-192/215-5p and their common pathways in Crohn's disease and colorectal cancer was also analyzed. Based on results derived from multiple approaches, we identified the biological functions of miR-192/215-5p as a tumor suppressor and link Crohn's disease and colorectal cancer by targeting triglyceride synthesis and extracellular matrix remodeling pathways.

Exosomal miRNAs as Novel Pharmacodynamic Biomarkers for Cancer Chemopreventive Agent Early Stage Treatments in Chemically Induced Mouse Model of Lung Squamous Cell Carcinoma. Cancers (Basel) 2019; 11:cancers11040477. [PMID: 30987362 PMCID: PMC6520832 DOI: 10.3390/cancers11040477] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2019] [Revised: 03/29/2019] [Accepted: 04/02/2019] [Indexed: 01/20/2023] Open
Abstract
Background: Chemopreventive agent (CPA) treatment is one of the main preventive options for lung cancer. However, few studies have been done on pharmacodynamic biomarkers of known CPAs for lung cancer. Materials and methods: In this study, we treated mouse models of lung squamous cell carcinoma with three different CPAs (MEK inhibitor: AZD6244, PI-3K inhibitor: XL-147 and glucocorticoid: Budesonide) and examined circulating exosomal miRNAs in the plasma of each mouse before and after treatment. Results: Compared to baselines, we found differentially expressed exosomal miRNAs after AZD6244 treatment (n = 8, FDR < 0.05; n = 55, raw p-values < 0.05), after XL-147 treatment (n = 4, FDR < 0.05; n = 26, raw p-values < 0.05) and after Budesonide treatment (n = 1, FDR < 0.05; n = 36, raw p-values < 0.05). In co-expression analysis, we found that modules of exosomal miRNAs reacted to CPA treatments differently. By variable selection, we identified 11, 9 and nine exosomal miRNAs as predictors for AZD6244, XL-147 and Budesonide treatment, respectively. Integrating all the results, we highlighted 4 miRNAs (mmu-miR-215-5p, mmu-miR-204-5p, mmu-miR-708-3p and mmu-miR-1298-5p) as the key for AZD6244 treatment, mmu-miR-23a-3p as key for XL-147 treatment, and mmu-miR-125a-5p and mmu-miR-16-5p as key for Budesonide treatment. Conclusions: This is the first study to use circulating exosomal miRNAs as pharmacodynamic biomarkers for CPA treatment in lung cancer.

miR-215 suppresses papillary thyroid cancer proliferation, migration, and invasion through the AKT/GSK-3β/Snail signaling by targeting ARFGEF1. Cell Death Dis 2019; 10:195. [PMID: 30814512 PMCID: PMC6393497 DOI: 10.1038/s41419-019-1444-1] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2018] [Revised: 01/29/2019] [Accepted: 02/14/2019] [Indexed: 12/13/2022]
Abstract
The incidence of papillary thyroid cancer (PTC) has been rapidly increasing in recent years. PTC is prone to lymph node metastasization, which further increases the recurrence rate and mortality of thyroid cancer. However, the underlying mechanisms of this process remain elusive. Several reports have shown that the microRNA miR-215 plays an important role in cancer metastasis. Here, we investigated, for the first time, the potential association between miR-215 and metastasis in PTC. The results of qPCR analysis demonstrated that miR-215 was downregulated in PTC cell lines and tissues, and lower levels of miR-215 correlated with lymph node metastasis of PTC. In vitro and in vivo assays revealed that restoration of miR-215 dramatically inhibited PTC cell proliferation and metastasis. We identified ADP ribosylation factor guanine nucleotide-exchange factor 1 (ARFGEF1) as the target, which mediated the function of miR-215. The expression of ARFGEF1 was inhibited by miR-215, and the effects of miR-215 were abrogated by re-expression of ARFGEF1. Moreover, we found that miR-215 suppressed PTC metastasis by modulating the epithelial–mesenchymal transition via the AKT/GSK-3β/Snail signaling. In summary, our study proves that miR-215 inhibits PTC proliferation and metastasis by targeting ARFGEF1 and indicates miR-215 as a biomarker for PTC prognosis.

Abstract
Tumor metastasis is a hallmark of cancer, with distant metastasis frequently developing in lung cancer, even at initial diagnosis, resulting in poor prognosis and high mortality. However, available biomarkers cannot reliably predict cancer spreading sites. The metastatic cascade involves highly complicated processes including invasion, migration, angiogenesis, and epithelial-to-mesenchymal transition that are tightly controlled by various genetic expression modalities along with interaction between cancer cells and the extracellular matrix. In particular, microRNAs (miRNAs), a group of small non-coding RNAs, can influence the transcriptional and post-transcriptional processes, with dysregulation of miRNA expression contributing to the regulation of cancer metastasis. Nevertheless, although miRNA-targeted therapy is widely studied in vitro and in vivo, this strategy currently affords limited feasibility and a few miRNA-targeted therapies for lung cancer have entered into clinical trials to date. Advances in understanding the molecular mechanism of metastasis will thus provide additional potential targets for lung cancer treatment. This review discusses the current research related to the role of miRNAs in lung cancer invasion and metastasis, with a particular focus on the different metastatic lesions and potential miRNA-targeted treatments for lung cancer with the expectation that further exploration of miRNA-targeted therapy may establish a new spectrum of lung cancer treatments.

Abstract
Our previous study revealed that selenium (Se) deficiency can cause myocardial injury through triggering autophagy. MicroRNAs (miRNAs) play crucial roles in autophagic cell death. However, the relationship between miRNAs and myocardial autophagy injury caused by Se deficiency remains unclear. We selected differential microRNA-215-5p (miR-215-5p) in Se-deficient myocardial tissue using high-throughput miRNA-sequencing. To further explore the role of miR-215-5p in myocardial injury, overexpression/knockdown of miR-215-5p in primary cardiomyocyte model was established by miRNAs interference technology. In this study, we report that miR-215-5p can promote myocardial autophagy by directly binding to the 3'untranslated region (3'UTR) of phosphatidylinositol-4, 5-bisphosphate 3-kinase (PI3K). Its target gene PI3K was confirmed by dual luciferase reporter assay, quantitative real-time polymerase chain reaction (qRT-PCR) and western blot in cardiomyocytes. Our results showed that overexpression of miR-215-5p could trigger myocardial autophagy through PI3K-threonine-protein kinase (AKT)-target of rapamycin (TOR) pathway. Further studies revealed that autophagic cell death was dependent on the activation of extracellular signal-regulated kinase1/2 (ERK1/2), c-Jun N-terminal kinase (JNK), p38 kinase (p38) and generation of reactive oxygen species (ROS) in overexpression of miR-215-5p in cardiomyocytes. On the contrary, miR-215-5p inhibitor can enhance cell survival capacity against autophagy by inhibiting ROS-mitogen-activated protein kinase (MAPK) pathways and activating the PI3K/AKT/TOR pathway in cardiomyocytes. Together, our findings support that miR-215-5p may modulate cell survival programs by regulating autophagy, and miR-215-5p acts as an autophagic regulator in the regulatory feedback loop that regulates cardiomyocyte survival by modulating the PI3K/AKT/TOR pathway and ROS-dependent MAPK pathways.

Abstract
An increasing number of studies have observed that microRNAs (miRNAs) are abnormally expressed in non-small cell lung cancer (NSCLC), and that their aberrant expression links with the progression and development of NSCLC. Therefore, it is necessary to full elucidate the specific roles of miRNAs in NSCLC, as this may facilitate the identification of novel therapeutic targets. In the present study, it was observed that miRNA-598 (miR-598) expression was significantly downregulated in NSCLC tissues and cell lines. Decreased miR-598 was negatively correlated with TNM stage and lymph node metastasis in NSCLC patients. In addition, ectopic expression of miR-598 reduced NSCLC cell proliferation and invasion in vitro. The zinc finger E-box-binding homeobox 2 (ZEB2) was validated as a direct target of miR-598 in NSCLC cells. ZEB2 was upregulated in NSCLC tissues and the upregulation of ZEB2 was inversely correlated with the miR-598 level. The results revealed that restored ZEB2 expression abrogated the inhibitory effects of miR-598 overexpression in NSCLC cells. In conclusion, the results of the present study revealed that miR-598 may inhibit the progression of NSCLC by directly targeting ZEB2, which suggests that this miRNA may be identified as a potential novel prognostic biomarker and therapeutic target for patients with NSCLC.

Abstract
BACKGROUND The introduction of immune check-point inhibition in non-small cell lung cancer (NSCLC) therapy represents improved prospects for the patients. The response rates to check-point inhibitors are approximately 20% in unselected NSCLC patients. Increasing levels of tumor PD-L1 expression are associated with higher response rates. However, patients with low PD-L1 levels may also have durable responses, and improved strategies for patient stratification are needed. MATERIAL AND METHODS In this study, we investigated circulating microRNAs aiming to identify circulating predictive biomarkers associated with increased overall survival after immune check-point treatment. Using next generation sequencing, we performed microRNA profiling in serum from NSCLC patients (n = 20) treated with nivolumab. Serum samples from 31 patients were used for validation using qPCR assays. Serum samples were collected prior to immune therapy initiation. RESULTS Based on multivariate regression analysis, we identified a signature of seven microRNAs (miR-215-5p, miR-411-3p, miR-493-5p, miR-494-3p, miR-495-3p, miR-548j-5p and miR-93-3p) significantly associated with overall survival (OS) > 6 months in discovery cohort (p = .0003). We further validated this in another similar set of samples (n = 31) and the model was significantly associated with overall survival (OS) > 6 months (p = .001) with sensitivity and specificity of 71% and 90%, respectively. CONCLUSIONS In this study of circulating microRNAs, we have identified a 7-miR signature associated with survival in nivolumab-treated NSCLC patients. This signature may lead to better treatment options for patients with NSCLC, but a validation in an independent cohort is needed to confirm the predicted potential.

Tian H, He Z. miR-215 Enhances HCV Replication by Targeting TRIM22 and Inactivating NF-κB Signaling. Yonsei Med J 2018; 59:511-518. [PMID: 29749134 PMCID: PMC5949293 DOI: 10.3349/ymj.2018.59.4.511] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Revised: 03/26/2018] [Accepted: 03/28/2018] [Indexed: 12/16/2022] Open
Abstract
PURPOSE Hepatitis C virus (HCV) infection is a major cause of liver disease. Several miRNAs have been found to be associated with HCV infection. This study aimed to investigate the functional roles and possible molecular mechanisms of miR-215 in HCV replication. MATERIALS AND METHODS The expression levels of miR-215 and TRIM22 were detected by quantitative real-time PCR (qRT-PCR) and western blot analysis in Con1b subgenomic genotype 1b HCV replicon cells (Con1b cells) and JFH1 full genome infecting Huh7.5.1 cells (Huh7.5.1 cells). HCV RNA levels were measured by qRT-PCR. The protein levels of NS3, NS5A, p65 subunit of NF-κB (p65), and phosphorylated p65 (p-p65) were determined by western blot analysis. The relationship between miR-215 and TRIM22 were explored by target prediction and luciferase reporter analysis. RESULTS miR-215 overexpression enhanced HCV replication in Con1b cells, while miR-215 knockdown suppressed HCV replication in Huh7.5.1 cells. TRIM22 was confirmed to be a direct target of miR-215. TRIM22 upregulation resulted in a decline in HCV replication, while TRIM22 inhibition led to enhancement of HCV replication. Additionally, exogenous expression of TRIM22 reversed the facilitating effect of miR-215 on HCV replication, while TRIM22 downregulation counteracted the inhibitory effect of miR-215 knockdown on HCV replication. Furthermore, miR-215 targeted TRIM22 to block the NF-κB pathway, and exerted a positively regulatory role on HCV replication. CONCLUSION miR-215 facilitated HCV replication via inactivation of the NF-κB pathway by inhibiting TRIM22, providing a novel potential target for HCV infection.

Abstract
Lung cancer remains the leading cause of cancer-associated mortality in China and worldwide. Increasing numbers of studies have demonstrated that microRNAs (miRNAs/miRs) have vital functions in numerous developmental processes and tumorigenesis. The aim of the present study was to investigate miR-154 expression in non-small cell lung cancer (NSCLC), and to explore the roles of miR-154 in the carcinogenesis and progression of this cancer. Reverse transcription-polymerase chain reaction (RT-qPCR) was performed to detect miR-154 expression in NSCLC tissues and cell lines. In addition, cell proliferation assay, migration and invasion assays were adopted to investigate the functional roles of miR-154 in NSCLC. Bioinformatics analysis, luciferase reporter assay, RT-qPCR and western blot analysis were used to explore the potential targets of miR-154 in NSCLC. According to the results, miR-154 was significantly downregulated in NSCLC tissues and cell lines. Restoration of miR-154 expression inhibited proliferation, migration and invasion of NSCLC cells. In addition, B-cell-specific Moloney murine leukemia virus insertion site 1 (BMI-1) was identified as a direct target gene of miR-154 in NSCLC. In conclusion, miR-154 may function as a tumor suppressor in NSCLC, partly by regulating BMI-1, and the modulation of miR-154 expression represents a potential strategy for the treatment of NSCLC patients.

MicroRNA-215 suppresses the proliferation, migration and invasion of non-small cell lung carcinoma cells through the downregulation of matrix metalloproteinase-16 expression. Exp Ther Med 2018; 15:3239-3246. [PMID: 29545841 PMCID: PMC5840942 DOI: 10.3892/etm.2018.5869] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2017] [Accepted: 12/15/2017] [Indexed: 02/06/2023] Open
Abstract
The present study investigated the expression of microRNA (miR)-215 in non-small cell lung carcinoma (NSCLC) at tissue and cellular levels, as well as its biological functions and mechanism of action. A total of 56 patients with NSCLC were included in the present study. NSCLC tissues and tumor-adjacent normal tissues were resected and collected. Reverse transcription-quantitative polymerase chain reaction was used to measure the expression of miR-215. Following transfection with miR-215 mimics, A549 cell proliferation, migration and invasion were determined using a Cell Counting Kit-8 and Transwell assay. Western blotting was employed to measure the expression of matrix metalloproteinase (MMP)-16 protein. A dual-luciferase reporter assay was conducted to determine the existence of a direct interaction between miR-215 and the MMP-16 gene. Reduced expression of miR-215 in NSCLC was closely associated with lymphatic metastasis and TNM staging. Overexpression of miR-215 inhibited the proliferation of A549 cells in vitro. Upregulated expression of miR-215 inhibited the migration and invasion of A549 cells in vitro. miR-215 exerted its biological functions possibly by regulating the expression of MMP-16. Elevated expression of MMP-16 promoted the proliferation, migration and invasion of A549 cells. miR-215 regulated the proliferation, migration and invasion of A549 cells by binding with the seed 3′-untranslated region of MMP-16 mRNA. The present study demonstrates that reduced expression of miR-215 in NSCLC is negatively associated with lymphatic metastasis and TNM staging. In addition, miR-215 acts as a tumor suppressor gene by inhibiting the proliferation, migration and invasion of NSCLC cells via the downregulation of MMP-16 expression.

A role for endothelial nitric oxide synthase in intestinal stem cell proliferation and mesenchymal colorectal cancer. BMC Biol 2018; 16:3. [PMID: 29329541 PMCID: PMC5795284 DOI: 10.1186/s12915-017-0472-5] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2017] [Accepted: 12/14/2017] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Nitric oxide (NO) has been highlighted as an important agent in cancer-related events. Although the inducible nitric oxide synthase (iNOS) isoform has received most attention, recent studies in the literature indicate that the endothelial isoenzyme (eNOS) can also modulate different tumor processes including resistance, angiogenesis, invasion, and metastasis. However, the role of eNOS in cancer stem cell (CSC) biology and mesenchymal tumors is unknown. RESULTS Here, we show that eNOS was significantly upregulated in VilCre ERT2 Apc fl/+ and VilCre ERT2 Apc fl/fl mouse intestinal tissue, with intense immunostaining in hyperproliferative crypts. Similarly, the more invasive VilCre ERT2 Apc fl/+ Pten fl/+ mouse model showed an overexpression of eNOS in intestinal tumors whereas this isoform was not expressed in normal tissue. However, none of the three models showed iNOS expression. Notably, when 40 human colorectal tumors were classified into different clinically relevant molecular subtypes, high eNOS expression was found in the poor relapse-free and overall survival mesenchymal subtype, whereas iNOS was absent. Furthermore, Apc fl/fl organoids overexpressed eNOS compared with wild-type organoids and NO depletion with the scavenger carboxy-PTIO (c-PTIO) decreased the proliferation and the expression of stem-cell markers, such as Lgr5, Troy, Vav3, and Slc14a1, in these intestinal organoids. Moreover, specific NO depletion also decreased the expression of CSC-related proteins in human colorectal cancer cells such as β-catenin and Bmi1, impairing the CSC phenotype. To rule out the contribution of iNOS in this effect, we established an iNOS-knockdown colorectal cancer cell line. NO-depleted cells showed a decreased capacity to form tumors and c-PTIO treatment in vivo showed an antitumoral effect in a xenograft mouse model. CONCLUSION Our data support that eNOS upregulation occurs after Apc loss, emerging as an unexpected potential new target in poor-prognosis mesenchymal colorectal tumors, where NO scavenging could represent an interesting therapeutic alternative to targeting the CSC subpopulation.

Abstract
Lung cancer is one of the most common type of cancers and the leading cause of cancer‑related mortality worldwide. Non-small cell lung cancer (NSCLC) accounts for >80% of lung cancer cases. Emerging studies have suggested that microRNAs are dysregulated in NSCLC and serve important roles in NSCLC initiation and development. However, to the best of our knowledge, the expression, roles and molecular mechanism of microRNA‑454 (miR‑454) have not been investigated in NSCLC. In the present study, miR‑454 was demonstrated to be significantly downregulated in NSCLC tissues and cell lines, as assessed by western blot analysis and reverse transcription‑quantitative polymerase chain reaction. Reduced miR‑454 expression was significantly correlated with aggressive clinicopathological features in NSCLC. In addition, upregulation of miR‑454 suppressed proliferation, migration and invasion NSCLC cells, as assessed by Cell Counting Kit‑8 and in vitro migration and invasion assays, respectively. Furthermore, bioinformatics analysis identified STAT3 as a direct target gene of miR‑454, and STAT3 knockdown was demonstrated to simulate the effects of miR‑454 overexpression in NSCLC. In conclusion, the present study provided convincing evidence that miR‑454 is downregulated in NSCLC, and regulates growth and metastasis by directly targeting STAT3, which suggests that miR‑454 may be an efficient therapeutic target for NSCLC.

Abstract
Barrett's esophagus (BE) is a premalignant lesion of esophageal adenocarcinoma. The aim of the present study was to investigate the possible mechanisms and biomarkers of BE. To identify the differentially expressed microRNAs (DEmiRNAs) and genes (DEGs) in BE, the miRNA expression profile GSE20099 and the gene expression profiles GSE26886, GSE13083 and GSE34619 were obtained from the Gene Expression Omnibus (GEO) database. DEGs and DEmiRNAs were screened for using the GEO2R tool. Using DAVID, functional and pathway enrichment analysis was performed to explore the biological function of identified DEGs. The protein-protein interaction (PPI) network was detected using STRING and constructed by Cytoscape software. Furthermore, targets of identified DEmiRNAs were predicted by the miRecords database, then integrated with the identified DEGs to obtain key genes involved in BE. In total, 311 DEGs were identified. These genes were significantly enriched in the pancreatic secretion, metabolic pathways and cytochrome P450 drug metabolism pathways. In the PPI network, 16 hub genes, including keratin 16, cystic fibrosis transmembrane conductance regulator, involucrin, protein kinase C α and cadherin 17 were identified. Following integration of the predicted target genes of DEmiRNAs with DEGs, three key BE genes were identified: PRKCA, CDH17 and epiregulin. In conclusion, a comprehensive bioinformatics analysis of identified DEGs and DEmiRNAs was performed to elucidate potential pathways and biomarkers involved in the development of BE.

Abstract
Growing evidence suggests that microRNAs are involved in the development and progression of colorectal cancer (CRC). In the present study, deregulation and functioning of tumor-suppressive miR-215-5p was evaluated in CRC. In total, 448 tumor tissues and 325 paired adjacent healthy tissues collected from Czech and Spain cohorts of CRC patients have been used for miR-215-5p expression analyses. A series of in vitro experiments have been performed using transient transfection of miR-215-5p mimics into four CRC cell lines to identify specific cellular processes affected by miR-215-5p. Further, the effects of miR-215-5p on tumor growth were evaluated in vivo using NSG mice and stable cell line overexpressing miR-215-5p. Target mRNAs of miR-215-5p were tested using luciferase assay and western blot analyses. We found that miR-215-5p is significantly downregulated in tumor tissues compared with non-tumor adjacent tissues and its decreased levels correlate with the presence of lymph node metastases, tumor stage, and shorter overall survival in CRC patients. Overexpression of miR-215-5p significantly reduced proliferation, clonogenicity, and migration of CRC cells, lead to cell cycle arrest in G2/M phase and p53-dependent induction of apoptosis. The ability of miR-215-5p to inhibit tumor growth was confirmed in vivo. Finally, we confirmed epiregulin and HOXB9 to be the direct targets of miR-215-5p. As epiregulin is EGFR ligand and HOXB9 is its transcriptional inducer, we suggest that the main molecular link between miR-215-5p and CRC cells phenotypes presents the EGFR signaling pathway, which is one of the canonical pathogenic pathways in CRC.

Abstract
Lung cancer is the second most common cancer and is the leading cause of cancer-related death worldwide. For decades, increasing evidence revealed that microRNAs may contribute to non‑small cell lung cancer (NSCLC) carcinogenesis and progression and could provide novel therapeutic targets for treatments of patients with NSCLC. Accumulated studies indicate that microRNA (miR)‑363‑3p serves important roles in tumorigenesis and tumor development; however, the role of miR‑363‑3p in NSCLC is still unclear. The current study reported that miR‑363‑3p exhibited reduced expression in NSCLC tissues and cell lines. Reduced miR‑363‑3p expression was correlated with tumor node metastasis classification and distant metastasis of NSCLC patients. Notably, miR‑363‑3p re‑expression significantly suppressed cell proliferation and invasion of NSCLC. Furthermore, bioinformatics analysis, luciferase reporter assay, reverse transcription‑quantitative polymerase chain reaction and western blotting indicated that (high mobility group AT-hook 2) HMGA2 was a direct target gene of miR‑363‑3p. HMGA2 was increased in NSCLC tissues and inversely associated with HMGA2 expression. Moreover, HMGA2 underexpression had similar effects to miR‑363‑3p overexpression in NSCLC cells. Thus, the current study suggested that miR‑363‑3p may act as a tumor suppressor in NSCLC and that the miR‑363‑3p could be investigated as a therapeutic target for the patients with this disease.

Abstract
Long non-coding RNAs (lncRNAs) are involved in the pathology of various tumors, including colorectal cancer (CRC). However, the role of lncRNA in CRC liver metastasis remains unclear. Methods: a microarray was performed to identify the differentially expressed lncRNAs between CRC tissues with and without liver metastasis. Survival analysis was evaluated using the Kaplan-Meier method and assessed using the log-rank test. In vitro and in vivo assays were preformed to explore the biological effects of the differentially expressed lncRNA in CRC cells. Results: the lncRNA UICLM (up-regulated in colorectal cancer liver metastasis) was significantly up-regulated in cases of CRC with liver metastasis. Moreover, UICLM expression was higher in CRC tissues than in normal tissues, and UICLM expression was associated with poor patient survival. Knockdown of UICLM inhibited CRC cell proliferation, invasion, epithelial-mesenchymal transition (EMT) and CRC stem cell formation in vitro as well as tumor growth and liver metastasis in vivo. Ectopic expression of UICLM promoted CRC cell proliferation and invasion. Mechanistic investigations revealed that UICLM induced its biological effects by regulating ZEB2, as the oncogenesis facilitated by UICLM was inhibited by ZEB2 depletion. Further study indicated that UICLM acted as a competing endogenous RNA (ceRNA) for miR-215 to regulate ZEB2 expression. Conclusions: taken together, our findings demonstrate how UICLM induces CRC liver metastasis and may offer a novel prognostic marker and therapeutic target for this disease.

miR-215 promotes cell migration and invasion of gastric cancer by targeting Retinoblastoma tumor suppressor gene 1. Pathol Res Pract 2017; 213:889-894.

Abstract
BACKGROUND Gastric cancer (GC) is one of the most common malignant tumor and has high mortality worldwide. microRNAs (miRNAs) play critical roles in carcinogenesis. Previous studied showed that miR-215 was involved in tumorigenesis and progression. This study was designed to clarify the biological function of miR-215 in GC. METHODS qRT-PCR was used to detect the miR-215 expression in GC tissues and 6 human GC cell lines (AGS, SGC-7901, NCI-N87, GES-1, MKN-45 and BGC-823) as well. Transwell assay was used to investigate the biological function of miR-215 in GC. Luciferase reporter assay was used to confirm its effect on the regulation of the target gene Retinoblastoma tumor suppressor gene 1 (RB1). RESULTS miR-215 was frequently up-regulated in GC tissues compared to adjacent non-tumor tissues and GC cell lines. miR-215 expression level was correlated with the progression of tumor invasion and tumor-node-metastasis (TNM) stage. Over-expression miR-215 in GC cell lines promoted cell migration and invasion. Besides, miR-215 could down-regulate the expression of RB1 in vitro via directly binding to its 3'-untranslated region (UTR), while the expression of RB1 would suppress the miR-215-indueced GC cell migration and invasion. CONCLUSIONS miR-215 promoted cell migration and invasion of gastric cancer by directly targeting RB1.

Abstract
There are accumulating reports that microRNAs are dysregulated in a number of human cancer types, and that they may function as tumor suppressors or oncogenes in tumorigenesis and tumor development. microRNA-215 (miR-215) has been identified as a tumor suppressor in epithelial ovarian, pancreatic, non-small cell lung and colon cancer, whereas it may act as an oncogene in gastric and cervical cancer. The role of miR-215 in breast cancer carcinogenesis and progression has yet to be elucidated. In the present study, the expression level of miR-215 was determined in breast cancer tissues and cell lines using the reverse transcription-quantitative polymerase chain reaction. The effects of miR-215 overexpression on proliferation and the invasive capacity of breast cancer cells were assessed using MTT and cell invasion assays. The results revealed that miR-215 was significantly downregulated in breast cancer tissues and cell lines. Restoration of miR-215 expression inhibited the proliferation and invasion of breast cancer cells. The underlying molecular mechanism for the suppression of proliferation and invasion by miR-215 was investigated. AKT serine/threonine kinase 1 (AKT1) was validated as a novel direct target of miR-215, and the effect of AKT1 small interfering RNA mimicked the effect of miR-215 overexpression in breast cancer cells. These results indicated that miR-215 acted as a tumor suppressor, and that its downregulation in tumor tissues may contribute to the carcinogenesis and progression of breast cancer, indicating that miR-215 may be a novel therapeutic target for the treatment of breast cancer.

Abstract
Cullin 4B (CUL4B), a scaffold protein that assembles CRL4B ubiquitin ligase complexes, is overexpressed in many types of cancers and represses many tumor suppressors through epigenetic mechanisms. However, the mechanisms by which CUL4B is upregulated remain to be elucidated. Here, we show that CUL4B is upregulated in non‐small‐cell lung carcinoma (NSCLC) tissues and is critically required for cell proliferation and migration in vitro and for xenograft tumor formation in vivo. We found that microRNA‐194 (miR‐194) and CUL4B protein were inversely correlated in cancer specimens and demonstrated that miR‐194 could downregulate CUL4B by directly targeting its 3′‐UTR. We also showed that CUL4B could be negatively regulated by p53 in a miR‐194‐dependent manner. miR‐194 was further shown to attenuate the malignant phenotype of lung cancer cells by downregulating CUL4B. Interestingly, CRL4B also epigenetically represses miR‐194 by catalyzing monoubiquitination at H2AK119 and by coordinating with PRC2 to promote trimethylation at H3K27 at the gene clusters encoding miR‐194. RBX1, another component in CRL4B complex, is also targeted by miR‐194 in NSCLC cells. Our results thus establish a double‐negative feedback loop between miR‐194 and CRL4B, dysregulation of which contributes to tumorigenesis. The function of miR‐194 as a negative regulator of CUL4B has therapeutic implications in lung cancer.

Abstract
MicroRNA-215 (miR-215) has been showed to play crucial roles in tumorigenesis and tumor progression in many types of cancer. However, its biological function and underlying mechanism in epithelial ovarian cancer (EOC) remains greatly unknown. The aims of this study were to investigate biological role and underlying mechanism of miR-215 in EOC. Here, we found that miR-215 expression was significantly decreased in EOC tissues or cell lines compared with adjacent normal tissues or normal ovarian cell line. Decreased miR-215 expression was significantly associated with International Federation of Gynaecology and Obstetrics (FIGO) stage and lymph node metastasis. Function analysis revealed that overexpression of miR-215 using miR-215 mimic significantly inhibit EOC cell proliferation, colony formation, migration and invasion in vitro. as well as suppress tumor growth in vivo. Moreover, we identified ribosome assembly factor NIN/RPN12 binding protein (NOB1) as a direct targets for miR-215 binding, resulting in suppression it expression, which in turn activated the MAPK signaling pathway. In clinical EOC specimens, NOB1 expression was upregulated, and inversely correlated with miR-215 expression (r = -0.675, P<0.001). Overexpression of NOB1 effectively rescued inhibition effect on EOC cells by induced miR-215 overexpression. Taken together, our findings suggested that miR-215 suppressed EOC growth and invasion by targeting NOB1.

Abstract
Metastasis is the spread and growth of localized cancer to new locations in the body and is considered the main cause of cancer-related deaths. Metastatic cancer cells display distinct genomic and epigenomic profiles and almost universally an aggressive pathophysiology. A better understanding of the molecular mechanisms and regulation of metastasis, including how metastatic tumors grow and survive in the nascent niche and the interactions of the emergent metastatic cancer cells within the local microenvironment may provide tools to design strategies to restrict metastatic dissemination. Aberrant microRNAs (miRNA) expression has been reported in metastatic cancer cells. MicroRNAs are known to regulate divergent and/or convergent metastatic gene pathways including activation of reprogramming switches during metastasis. An in-depth understanding of role of miRNAs in the metastatic cascade may lead to the identification of novel targets for anti-metastatic therapeutics as well as potential candidate miRNAs for cancer treatment. This review primarily focuses on the role of miRNAs in the mechanisms of cancer metastasis as well as implications for metastatic cancer treatment.

microRNA-145 modulates epithelial-mesenchymal transition and suppresses proliferation, migration and invasion by targeting SIP1 in human cervical cancer cells. Cell Oncol (Dordr) 2016; 40:119-131.

Abstract
PURPOSE Previously, it has been reported that microRNA-145 (miR-145) is lowly expressed in human cervical cancers and that its putative tumour suppressive role may be attributed to epithelial-mesenchymal transition (EMT) regulation. Here, we aimed to assess whether miR-145 may affect EMT-associated markers/genes and suppress cervical cancer growth and motility, and to provide a mechanistic basis for these phenomena. METHODS The identification of the SMAD-interacting protein 1 (SIP1) mRNA as putative miR-145 target was investigated using a 3' untranslated region (3'UTR) luciferase assay and Western blotting, respectively. The functional effects of exogenous miR-145 expression, miR-145 suppression or siRNA-mediated SIP1 expression down-regulation in cervical cancer-derived C33A and SiHa cells were analysed using Western blotting, BrdU incorporation (proliferation), transwell migration and invasion assays. In addition, the expression levels of miR-145 and SIP1 were determined in primary human cervical cancer and non-cancer tissue samples using qRT-PCR. RESULTS We found that miR-145 binds to the wild-type 3'UTR of SIP1, but not to its mutant counterpart, and that, through this binding, miR-145 can effectively down-regulate SIP1 expression. In addition, we found that exogenous miR-145 expression or siRNA-mediated down-regulation of SIP1 expression attenuates the proliferation, migration and invasion of C33A and SiHa cells and alters the expression of the EMT-associated markers CDH1, VIM and SNAI1, whereas inhibition of endogenous miR-145 expression elicited the opposite effects. The expression of miR-145 in cervical cancer tissue samples was found to be low, while that of SIP1 was found to be high compared to non-cancerous cervical tissues. An inverse expression correlation between the two was substantiated through the anlaysis of data deposited in the TCGA database. CONCLUSION Our data indicate that low miR-145 expression levels in conjunction with elevated SIP1 expression levels may contribute to cervical cancer development. MiR-145-mediated regulation of SIP1 provides a novel mechanistic basis for its tumour suppressive mode of action in human cervical cancer cells.

Abstract
MicroRNAs (miRNAs) are small ∼22 nucleotide regulatory RNAs that regulate the stability and translation of cognate mRNAs. MiRNAs participate in the regulation of adipogenesis, and identification of the full repertoire of miRNAs expressed in adipose tisse is likely to improve our understanding of adipose tissue growth and development significantly. In the present study, miR-215-5p was found to inhibit adipocyte differentiation of 3T3-L1 cells. Moreover, fibronectin type III domain containing 3B (FNDC3B) and catenin, beta interacting protein 1 (CTNNBIP1) were found to be direct targets of miR-215-5p. Further studies in mouse 3T3-L1 cell-line suggests that miR-215-5p is a negative regulator of adipocyte differentiation through post-transcriptional regulation of FNDC3B and CTNNBIP1 during early adipogenesis.
