[PMID: 37964399 DOI: 10.1111/odi.14802] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 10/08/2023] [Accepted: 10/23/2023] [Indexed: 11/16/2023]
Abstract
OBJECTIVES To assess the role of TNF-α/TNFR2 axis on promoting angiogenesis in oral squamous cell carcinoma (OSCC) cells and uncover the underlying mechanisms. MATERIALS AND METHODS The expression of TNFR2 and CD31 in OSCC tissues was examined; gene expression relationship between TNF-α/TNFR2 and angiogenic markers or signaling molecules was analyzed; the expression of angiogenic markers, signaling molecules, TNFR1, and TNFR2 in TNF-α-stimulated OSCC cells treated with or without TNFR2 neutralizing antibody (TNFR2 Nab) were assessed; the concentration of angiogenic markers in the supernatant of OSCC cells was detected; conditioned mediums of OSCC cells treated with TNF-α or TNF-α + TNFR2 Nab were applied to human umbilical vein endothelial cells (HUVECs), followed by tube formation and cell migration assays. RESULTS Significantly elevated expression of TNFR2 and CD31 in OSCC tissues was observed. A positive gene expression correlation was identified between TNF-α/TNFR2 and angiogenic markers or signaling molecules. TNFR2 Nab inhibited the effects of TNF-α on enhancing the expression of angiogenic factors and TNFR2, the phosphorylation of the Akt/mTOR signaling pathway, HUVECs migration, and tube formation. CONCLUSIONS TNFR2 Nab counteracts the effect of TNF-α on OSCC cells through the TNFR2/Akt/mTOR axis, indicating that blocking TNFR2 might be a promising strategy against cancer.

The imminent role of microRNAs in salivary adenoid cystic carcinoma. Transl Oncol 2022; 27:101573. [PMID: 36335706 PMCID: PMC9646983 DOI: 10.1016/j.tranon.2022.101573] [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: 08/22/2022] [Revised: 10/01/2022] [Accepted: 10/18/2022] [Indexed: 11/06/2022] Open
Abstract
Unfortunately, despite the severe problem associated with salivary adenoid cystic carcinoma (SACC), it has not been studied in detail yet. Therefore, the time has come to understand the oncogenic cause of SACC and find the correct molecular markers for diagnosis, prognosis, and therapeutic target to tame this disease. Recently, we and others have suggested that non-coding RNAs, specifically microRNAs and long non-coding RNAs, can be ideal biomarkers for cancer(s) diagnosis and progression. Herein, we have shown that various miRNAs, like miR-155, miR‑103a‑3p, miR-21, and miR-130a increase the oncogenesis process, whereas some miRNAs such as miR-140-5p, miR-150, miR-375, miR-181a, miR-98, miR-125a-5p, miR-582-5p, miR-144-3p, miR-320a, miR-187 and miR-101-3p, miR-143-3p inhibit the salivary adenoid cystic carcinoma progression. Furthermore, we have found that miRNAs also target many vital genes and pathways like mitogen-activated protein kinases-snail family transcriptional repressor 2 (MAPK-Snai2), p38/JNK/ERK, forkhead box C1 protein (FOXC1), mammalian target of rapamycin (mTOR), integrin subunit beta 3 (ITGB3), epidermal growth factor receptor (EGFR)/NF-κB, programmed cell death protein 4 (PDCD4), signal transducer and activator of transcription 3 (STAT3), neuroblastoma RAS (N-RAS), phosphatidylinositol-3-kinase (PI3K)/Akt, MEK/ERK, ubiquitin-like modifier activating enzyme 2 (UBA2), tumor protein D52 (TPD52) which play a crucial role in the regulation of salivary adenoid cystic carcinoma. Therefore, we believe that knowledge from this manuscript will help us find the pathogenesis process in salivary adenoid cystic carcinoma and could also give us better biomarkers of diagnosis and prognosis of the disease.

Abstract
Oral squamous cell carcinoma (SCC) is a prevalent malignant disease worldwide, especially so in Taiwan. Early- or even preclinical-stage detection is critical for reducing morbidity and mortality from oral SCC. Epidemiological and genome association studies are useful for identifying clinicopathological risk factors for preventive, diagnostic, and therapeutic approaches of oral SCC. For advanced oral SCC, effective treatments are critical to prolonging survival and enhancing quality of life. As oral SCC is characteristic of regional invasion with lymph node metastases, understanding the aggressive features of oral SCC, particularly in lymphangiogenesis, is essential for determining effective treatments. Emerging evidence has demonstrated that the tumor microenvironment (TME) plays a pivotal role in tumor growth, invasion, and metastases. Recent clinical successes in immune checkpoint inhibitors either alone or combined with chemotherapy have also supported the therapeutic value of immunotherapy in oral SCC. This review summarizes critical advances in basic knowledge of oral SCC from the perspective of clinicopathological risk factors, molecular tumorigenesis, and the TME. We also highlight our recent investigations on the microbiome, genome association studies, lymphangiogenesis, and immunomodulation in oral SCC. This review may provide new insights for oral SCC treatment by systematically interpreting emerging evidence from various preclinical and clinical studies.

Abstract
Context: The diagnosis and grading of epithelial dysplasia is based on a combination of architectural and cytological changes. A gradual increase in quantitative DNA aberrations has been found to correlate with increasing degree of dysplasia in oral mucous membranes. Aims: The aim of this study is to assess nuclear parameters in potentially malignant and malignant lesions of the oral cavity and to assess cytomorphometric changes in the nucleus and nucleolus in oral epithelial dysplasia (OED), oral submucous fibrosis (OSMF), oral squamous cell carcinoma (OSCC) and normal oral mucosa using methyl green-pyronin staining to determine its suitability for detecting potentially malignant lesions and the stage of carcinogenesis. Methods: Forty-five archival sections of OED, OSMF and OSCC and 5 cases of normal oral mucosa as the control group were stained according to methyl green-pyronin-staining protocol. Cytomorphometric parameters such as nuclear diameter, nucleolar diameter, number of nucleoli and cytoplasmic RNA were assessed. Statistical Analysis Used: The study was subjected to statistical analysis to evaluate the association between morphometric parameters using analysis of variance test, followed by Bonferroni's post hoc analysis. Results: A progressive increase in the nuclear parameters as well as cytoplasmic RNA content was observed between normal mucosa through dysplasia and OSMF to OSCC. Conclusion: This study serves as an effective diagnostic aid in assessing nuclear parameters in potentially malignant and malignant epithelial lesions affecting oral cavity.

Abstract
BACKGROUND p-Coumaric acid (p-CA), a phenolic compound abundantly found in edible plants, was found to induce apoptosis in SNU-16 gastric cancer cells. However, the effects of p-CA on the microRNA expression pattern in SNU-16 cells have not been reported. OBJECTIVES The primary objective of this study was to investigate microRNA expression profiles in p-CA-treated SNU-16 cells. METHODS SNU-16 cells were treated with 1.5 mM p-CA for 48 h. High-throughput RNA sequencing was performed. The accuracy and validity of the RNA sequencing results were tested by real-time PCR. Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed using the differentially expressed microRNAs (DEMs). RESULTS Thirty-two DEMs were identified between p-CA-treated and control cells, 9 of which were upregulated, and 23 downregulated. GO and KEGG pathway analyses of the target genes indicated that these genes were involved in a variety of biological functions and several cancer-related pathways. The miRNA interactive network analysis identified hsa-miR-125a-5p, hsa-miR-30a-5p, and hsa-miR-7-5p as the major nodes. CONCLUSIONS Our findings indicated that p-CA exerted its anticancer effects in SNU-16 gastric cancer cells by modulating the expression of certain microRNAs, providing a better understanding of the anticancer properties of p-CA in gastric cancer cells.

SNHG17 enhances the malignant characteristics of tongue squamous cell carcinoma by acting as a competing endogenous RNA on microRNA-876 and thereby increasing specificity protein 1 expression. Cell Cycle 2020; 19:711-725. [PMID: 32089063 PMCID: PMC7145335 DOI: 10.1080/15384101.2020.1727399] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2019] [Revised: 11/09/2019] [Accepted: 11/18/2019] [Indexed: 12/13/2022] Open
Abstract
A long noncoding RNA called SNHG17 (small nucleolar RNA host gene 17) is aberrantly expressed and plays essential roles in multiple human cancer types. Nevertheless, its expression pattern and specific functions in tongue squamous cell carcinoma (TSCC) have not been well studied until now. Hence, in this study, we aimed to measure SNHG17 expression in TSCC and to examine the actions of SNHG17 on the malignant characteristics of TSCC cells. The regulatory mechanism that mediates the oncogenic effects of SNHG17 on TSCC cells was investigated too. In this study, SNHG17 was found to be upregulated in TSCC, and this overexpression closely correlated with adverse clinical parameters and shorter overall survival among the patients with TSCC. The SNHG17 knockdown significantly decreased TSCC cell proliferation, migration, and invasion in vitro and tumor growth in vivo. Mechanism investigation revealed that SNHG17 acts as a competing endogenous RNA on microRNA-876 (miR-876) in TSCC cells. In addition, specificity protein 1 (SP1) was validated as a direct target gene of miR-876 in TSCC cells. SP1 expression restoration in TSCC cells reversed miR-876 overexpression-induced anticancer effects. MiR-876 downregulation strongly attenuated the actions of the SNHG17 knockdown in TSCC cells. SNHG17 plays an oncogenic part in TSCC cells both in vitro and in vivo via sponging of miR-876 and thereby upregulating SP1, which could be regarded as a promising target for TSCC therapy.

Abstract
Background Circular RNAs (circRNAs), a newly-discovered class of non-coding RNAs, have a significant role in the progression of cancers, but the effect of hsa_circ_0086414 in human oral squamous cell carcinoma (OSCC) is still unclear. Material/Methods The circRNAs expression profile in OSCC tissue samples was assessed by high-throughput sequencing. The hsa_circ_0086414 expression level in 55 paired OSCC tissue samples and 2 kinds of OSCC cells was evaluated by quantitative real-time polymerase chain reaction (qRT-PCR). Additionally, the correlation between the hsa_circ_0086414 expression and clinicopathological characteristics of individuals with OSCC was studied. We used receiver operating characteristic (ROC) curves to observe the hsa_circ_0086414 value of diagnosis in OSCC. The network of hsa_circ_0086414-miRNAs-mRNAs was constructed. Gene Ontology (GO), Disease Oncology (DO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were carried out based on sequencing data and bioinformatics predictions. Results Hsa_circ_0086414 expression in OSCC tissue samples and OSCC cells was first discovered to be significantly downregulated compared with the adjacent healthy tissues (AHTs) and normal (HaCaT) cells, respectively. Moreover, its expression level was significantly correlated with stage in TNM, size of tumor, and lymph node metastasis. The area below the ROC curve was 0.749. Hsa_circ_0086414-miRNAs-mRNAs network analysis and GO, DO, and KEGG analyses all demonstrated that hsa_circ_0086414 is correlated with cancer progression to a certain extent. Conclusions We discovered that hsa_circ_0086414 might be an essential diagnostic biomarker in OSCC. Furthermore, hsa_circ_0086414 could be a target for OSCC therapy.

Abstract
Tongue squamous cell carcinoma (TSCC) is one of the most common incident oral cancers, which is accompanied by high rate of metastasis and recurrence. It has been demonstrated that elevated interleukin-8 (IL-8) promoted metastasis of various cancers via regulating epithelial-mesenchymal transition (EMT) process, whereas the accurate mechanism is left to be elucidated. The present work was aimed to investigate the role of microRNA-940 (miR-940)/C-X-C chemokine receptor type 2 (CXCR2) system in the metastasis ability and EMT process of IL-8-treated TSCC cells and further explore the underlying mechanisms. We found that miR-940 up-regulation inhibited IL-8-induced migration and invasion, which could be deprived by CXCR2 silence. We also observed that miR-940 suppressed epithelial marker E-cadherin expression while increased mesenchymal markers N-cadherin and Twist levels in IL-8-stimulated TSCC cells. Besides, IL-8-induced invasion and EMT process of TSCC cells were impeded in the present of the NF-κB inhibitor, PDTC or BAY117082. In conclusion, our data demonstrated that miR-940/CXCR2 system regulated the metastasis of TSCC cells via NF-κB-induced EMT process.

Abstract
Distant metastasis leads oral cancer patients into a poor survival rate and a high recurrence stage. During tumor progression, dysregulated microRNAs (miRNAs) have been reported to involve tumor initiation and modulate oral cancer malignancy. MiR-450a was significantly upregulated in oral squamous cell carcinoma (OSCC) patients without functional reports. This study was attempted to uncover the molecular mechanism of novel miR-450a in OSCC. Mir-450a expression was examined by quantitative RT-PCR, both in OSCC cell lines and patients. Specific target of miR-450a was determined by software prediction, luciferase reporter assay, and correlation with target protein expression. The functions of miR-450a and TMEM182 were accessed by adhesion and transwell invasion analyses. Determination of the expression and cellular localization of TMEM182 was examined by RT-PCR and by immunofluorescence staining. The signaling pathways involved in regulation of miR-450a were investigated using the kinase inhibitors. Overexpression of miR-450a in OSCC cells impaired cell adhesion ability and induced invasiveness, which demonstrated the functional role of miR-450a as an onco-miRNA. Interestingly, tumor necrosis factor alpha (TNF-α)-mediated expression of TMEM182 was regulated by miR-450a induction. MiR-450a-reduced cellular adhesion was abolished by TMEM182 restoration. Furthermore, the oncogenic activity of TNF-α/miR-450a/TMEM182 axis was primarily through activating extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway. ERK1/2 inhibitor prevented the TNF-α-induced miR-450a expression and enhanced adhesion ability. Our data suggested that TNF-α-induced ERK1/2-dependent miR-450a against TMEM182 expression exerted a great influence on increasing OSCC motility. Overall, our results provide novel molecular insights into how TNF-α contributes to oral carcinogenesis through miR-450a that targets TMEM182.

Abstract
Long non-coding RNAs (lncRNAs) are a group of biomarkers which can regulate the biological processes of various human cancers. LncRNA HNF1A-AS1 has been reported in human cancers for its oncogenic role. This study focused on the biological function and molecular mechanism of HNF1A-AS1 in oral squamous cell carcinoma (OSCC). The high expression of HNF1A-AS1 was examined in OSCC tissues and cell lines. Kaplan Meier method revealed that high expression of HNF1A-AS1 predicted poor prognosis for patients with OSCC. Results of loss-of-function assays demonstrated that silenced HNF1A-AS1 inhibited the proliferation, migration and epithelial-mesenchymal transition (EMT) of OSCC cells. Mechanically, HNF1A-AS1 was positively regulated by the transcription factor STAT3. Recently, Notch signaling pathway has been reported in human malignancies. In this study, we analyzed the correlation between HNF1A-AS1 and Notch signaling pathway. It was uncovered that the expression of Notch1 and Hes1 (the core factors of Notch signaling pathway) was negatively regulated by HNF1A-AS1 knockdown. Rescue assays further demonstrated the positive regulatory effects of HNF1A-AS1 on Notch signaling pathway in OSCC. In conclusion, upregulation of HNF1A-SA1 induced by transcription factor STAT3 promotes OSCC progression by activating Notch signaling pathway.

Abstract
Human Papilloma Virus infection is very frequent in humans and is mainly transmitted sexually. The majority of infections are transient and asymptomatic, however, if the infection persists, it can occur with a variety of injuries to skin and mucous membranes, depending on the type of HPV involved. Some types of HPV are classified as high oncogenic risk as associated with the onset of cancer. The tumors most commonly associated with HPV are cervical and oropharyngeal cancer, epigenetic mechanisms related to HPV infection include methylation changes to host and viral DNA and chromatin modification in host species. This review is focused about epigenethic mechanism, such as MiRNAs expression, related to cervix and oral cancer. Specifically it discuss about molecular markers associated to a more aggressive phenotype. In this way we will analyze genes involved in meiotic sinaptonemal complex, transcriptional factors, of orthokeratins, sinaptogirin, they are all expressed in cancer in a way not more dependent on cell differentiation but HPV-dependent.

Abstract
Recently, increasing evidence has indicated that lncRNAs may play a critical role in the progression of oral cancer (OC). However, whether lncRNA-ANRIL is involved in the tumorigenesis of OC remains undetermined. In the present study, ANRIL showed significantly higher, while miR-125a showed lower, expression in OC tissues and sera than in normal controls. MTT, colony formation, flow cytometry analysis, wound-healing, transwell and mice xenograft model assays were used to detect the proliferation, migration, and invasion of ARNIL-overexpressing HB56 cells and ARNIL-knockdown CAL27 cells. The results showed that cell proliferation, migration, and invasion were significantly increased by ARNIL overexpression and decreased by ARNIL silencing in oral cancer cells. Furthermore, we found a negative correlation between ARNIL and miR-125a, and ARNIL acts as a miRNA-sponge by directly interacting with miR-125a.

Abstract
Epigenetic modifications have emerged into one of the cancer hallmarks, replacing the concept of malignant pathologies as being solely genetic-based conditions. The epigenetic landscape is responsible for normal development but also for the heterogeneity among tissues in terms of gene expression patterns. Dysregulation in these mechanisms has been associated with disease stage, and increased attention is now granted to cancer in order to take advantage of these modifications in terms of novel therapeutic strategies or diagnosis/prognosis tools. Oral cancer has also been subjected to epigenetic analysis with numerous studies revealing that the development and progression of this malignancy are partially induced by an altered epigenetic substrate together with genetic alterations and prolonged exposure to environmental risk factors. The present review summarizes the most important epigenetic modifications associated with oral cancer and also their potential to be used as new therapeutic targets.

Abstract
Betel nut chewing is associated with oral cavity cancer. Radiotherapy is one of the therapeutic approaches. Here, we used miR-17-5p antisense oligonucleotides (AS-ODNs) and human apoptosis protein array to clarify which apoptosis-related proteins are increased or decreased by miR-17-5p in betel nut chewing- oral squamous cell carcinoma OC3 cells. Furthermore, miR-17-5p AS-ODN was used to evaluate the radio-sensitization effects both in vitro and in vivo. An OC3 xenograft tumor model in severe combined immunodeficiency mice was used to determine the effect of miR-17-5p AS ODN on tumor irradiation. We simultaneously detected the relative expressions of 35 apoptosis-related proteins in irradiated OC3 cells that were treated with miR-17-5p AS-ODN or a control ODN. Several proteins, including p21, p53, TNF RI, FADD, cIAP-1, HIF-1α, and TRAIL R1, were found to be up- or downregulated by miR-17-5p in OC3 cells; their expression patterns were also confirmed by Western blotting. We further clarified the role of p53 in irradiated OC3 cells, using a p53 overexpression strategy. The results revealed that the enhancement of p53 expression significantly enhanced radiation-induced G2/M arrest of the OC3 cells. In the in vivo study, treatment of miR-17-5p AS-ODN before irradiation significantly enhanced p53 expression and reduced tumor growth. These results suggest that miR-17-5p increases or decreases apoptosis-related proteins in irradiated OC3 cells; its effect on p53 protein expression contributes to the modulation of the radiosensitivity of the OC3 cells.

Abstract
BACKGROUND Oral squamous cell carcinomas (OC) are life-threatening diseases emerging as major international health concerns. OBJECTIVE Development of an efficient clinical strategy for early diagnosis of the disease is a key for reducing the death rate. Biomarkers are proven to be an effective approach for clinical diagnosis of cancer. Although mechanisms underlying regulation of oral malignancy are still unclear, microRNAs (miRNAs) as a group of small non-coded RNAs may be developed as the effective biomarkers used for early detection of oral cancer. METHODS A literature search was conducted using the databases of PubMed, Web of Science, and the Cochrane Library. The following search terms were used: miRNAs and oral cancer or oral carcinoma. A critical appraisal of the included studies was performed with upregulated miRNAs and downregulated miRNAs in oral cancer. RESULTS In this review, we summarize the research progress made in miRNAs for diagnosis of oral cancer. The involvement of miRNAs identified in signal transduction pathways in OC, including Ras/MAPK signaling, PI3K/AKT signaling, JAK/STAT signaling, Wnt/β-catenin signaling, Notch signaling, and TGF-β/SMAD signaling pathway. CONCLUSIONS A number of studies demonstrated that miRNAs may be developed as an ideal set of biomarkers used for early diagnosis and prognosis of cancers because of the stability in human peripheral blood and body fluids and availability of non-invasive approaches being developed for clinical utility. CLINICAL RELEVANCE These findings suggest that miRNAs as biomarkers may be useful for diagnosis of OC.

Abstract
Objective Neurotropism of salivary adenoid cystic carcinoma (SACC) and pulmonary metastasis may lead to in treatment failure. miR-582-5p plays important roles in tumorigenesis, invasion and migration. Here, we aim to determine the effect of miR-582-5p and its role in SACC invasion and metastasis. Methods Six primary human SACC samples and matching adjacent normal tissues were analyzed by microarray analysis. Next, quantitative real-time PCR was carried out to evaluate miR-582-5p expression in 16 primary human SACC samples and matching adjacent normal tissues. Cell invasion and migration were also analyzed, and a luciferase reporter assay and western analysis were conducted. Cell growth and apoptosis assay were performed to confirm the effect of miR-582-5p and Forkhead box C1 (FOXC1) siRNA in cell proliferation and apoptosis. SACC tumorigenesis and metastasis were investigated in vivo experiment. Clinical samples from 110 patients were analyzed using in situ hybridization and immunohistochemistry. Results Microarray analysis revealed that miR-582-5p was significantly downregulated in the SACC samples compared with the matching adjacent normal tissues. Regulation of miR-582-5p expression significantly influenced the migration, invasion and proliferation ability of SACC cells by targeting FOXC1. E-cadherin was increased, while vimentin and snail were decreased with downregulation of FOXC1, suggesting that FOXC1 may regulate the epithelial-to-mesenchymal transition (EMT) of SACC cells by transactivating snail. In vivo, miR-582-5p overexpression suppressed the tumorigenesis and pulmonary metastasis of SACC. Lower expression of miR-582-5p expression predicts unfavorable prognoses and high rates of metastasis. Conclusions miR-582-5p could suppress effect on the process of invasion and migration in SACC cell lines, and this could occur through its target gene FOXC1.

circRNA_100290 plays a role in oral cancer by functioning as a sponge of the miR-29 family. Oncogene 2017; 36:4551-4561.

Abstract
Circular RNAs (circRNAs) represent a class of non-coding RNAs that are widely expressed in mammals. However, it is largely unknown about the function of human circRNAs and the roles of circRNAs in human oral squamous cell carcinomas (OSCC). Here we performed a comprehensive study of circRNAs in human OSCC using circRNA and mRNA microarrays, and identified many circRNAs that are differentially expressed between OSCC tissue and paired non-cancerous matched tissue. We further found a circRNA termed circRNA_100290 that served as a critical regulator in OSCC development. We discovered that circRNA_100290 was upregulated and co-expressed with CDK6 in OSCC tissue. Knockdown of circRNA_100290 decreased expression of CDK6 and inhibited proliferation of OSCC cell lines in vitro and in vivo. Via luciferase reporter assays, circRNA_100290 was observed to directly bind to miR-29 family members. Further EGFP/RFP reporter assays showed that CDK6 was the direct target of miR-29b. Taken together, we conclude that circRNA_100290 may function as a competing endogenous RNA to regulate CDK6 expression through sponging up miR-29b family members. Taken together, it indicates that circRNAs may exert regulatory functions in OSCC and may be a potential target for OSCC therapy.

Abstract
Purpose The constitutive activation of the Ras–MEK–ERK signaling pathway in oral cavity squamous cell carcinoma (OSCC) has been found to be tightly controlled at multiple levels under physiological conditions. RASA1 and SPRED1 are two important negative regulators of this pathway, but the exact regulating mechanism remains unclear. In this study, we aimed to explore the potential regulating mechanisms involved in the Ras–MEK–ERK signaling pathway in OSCC. Materials and methods MicroRNA (miRNA) expression was detected by quantitative reverse-transcription polymerase chain reaction. The protein levels of RASA1, SPRED1, and signaling proteins were detected by Western blot. Cell growth was determined using CCK-8 reagent, colony formation was stained by crystal violet, and cell invasion was tested using transwell chambers. Cell apoptosis and the cell cycle were then analyzed by flow cytometry. The binding of miR182 with RASA1 or SPRED1 was evaluated by luciferase reporter assays on a dual-luciferase reporter system. Results The expression of miR182 was found to be upregulated significantly in malignant oral carcinoma tissues compared with the adjacent nonmalignant tissues, and was inversely correlated with protein levels of RASA1 and SPRED1. Overexpression of miR182 in OSCC cell lines sustained Ras–MEK–ERK signaling-pathway activation, and promoted cell proliferation, cell-cycle progression, colony formation, and invasion capacity, whereas miR182 downregulation alleviated these properties significantly in vitro. Furthermore, we demonstrated that miR182 exerted its oncogenic role in OSCC by directly targeting and suppressing RASA1 and SPRED1. Conclusion Our results bring new insights into the important role of miR182 in the activation of the Ras–MEK–ERK signaling pathway, and suggest that miR182 may be used as a potential target for treatment of OSCC, prompting further investigation into miRNA antisense oligonucleotides for cancer therapy.

miR clusters target cellular functional complexes by defining their degree of regulatory freedom. Cancer Metastasis Rev 2017; 35:289-322.

Abstract
Using the two paralog miR-23∼27∼24 clusters as an example and combining experimental and clinical data in a systematical approach to microRNA (miR) function and dysregulation, a complex picture of their roles in cancer is drawn. Various findings appear to be contradictory to a larger extent and cannot be fully explained by the classical regulatory network models and feedback loops that are mainly considered by one-to-one regulatory interactions of the involved molecules. Here, we propose an extended model of the regulatory role of miRs that, at least, supplements the usually considered single/oligo-target regulation of certain miRs. The cellular availability of the participating miR members in this model reflects an upper hierarchy level of intracellular and extracellular environmental influences, such as neighboring cells, soluble factors, hypoxia, chemotherapeutic drugs, and irradiation, among others. The novel model is based on the understanding of cellular functional complexes, such as for apoptosis, migration, and proliferation. These complexes consist of many regulatory components that can be targeted by miR cluster members to a different extent but may affect the functional complex in different ways. We propose that the final miR-related effect is a result of the possible degree of regulatory freedom provided by the miR effects on the whole functional complex structure. This degree of regulatory freedom defines to which extent the cellular functional complex can react in response to regulatory triggers, also understood as sensitization (more regulatory response options) or de-sensitization (less regulatory response options) of the system rather than single molecules.

Abstract
Although less than 3% of the genome encodes proteins, at least 75% of the genome is transcribed into RNAs with no protein-coding potential (noncoding RNAs [ncRNAs]). On the basis of their size and the arbitrary 200 nucleotides cutoff, ncRNAs are classified into long ncRNAs (lncRNAs) or small ncRNAs (including microRNAs). Over the last few years, the role of microRNAs in oral squamous cells carcinoma (OSCC) has been extensively addressed, but the possible role of lncRNAs in OSCC remains unclear. We aimed to explore and discuss the potential role of lncRNAs in OSCC. The detection of lncRNAs in saliva holds promise not only as a noninvasive diagnostic tool in OSCC but also in the early detection of oral cancer recurrence. lncRNAs are promising future therapeutic targets in the OSCC scenario, and research in this field may expand greatly in the next decade.

Abstract
Abnormal expression of microRNAs (miRNAs) is involved in the development of and anti-apoptotic effects in various types of human cancer. However, miRNA-mediated regulation of oral verrucous carcinoma (OVC) remains to be elucidated. The present study aimed to investigate the expression of miR-181b in OVC and oral squamous cell carcinoma (OSCC). The expression levels of miR-181b were determined using reverse transcription-quantitative polymerase chain reaction. The expression levels of B-cell lymphoma 2 (Bcl-2) and leucine rich repeats and immunoglobulin like domains 1 (LRIG1), were evaluated using immunohistochemical staining. The correlation between Bcl-2 and LRIG1 expression was determined using a Pearson correlation analysis. The expression levels of miR-181b and Bcl-2 in OVC were significantly higher compared with normal mucosal tissue (NM); however, lower compared with the OSCC. The key target of miR-181b was LRIG1 and it was significantly lower in OVC tissues compared with NM tissue; however this was higher when compared with OSCC tissue. The expression levels of Bcl-2 were correlated with expression levels of LRIG1 in OVC tissues. Therefore, LRIG1 may be associated with anti-apoptotic function in OVC tissues.

[PMID: 24565984 DOI: 10.1016/j.oraloncology.2014.01.014] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2013] [Revised: 01/16/2014] [Accepted: 01/23/2014] [Indexed: 12/27/2022]
Abstract
OBJECTIVE RhoC a pro-metastatic oncogene is constitutively active in many head and neck squamous cell carcinomas. MicroRNA-138 which possesses a documented tumor suppressor function can bind to the 3'UTR of RhoC mRNA and inhibit its activity. We hypothesize that miR-138 can inhibit the function of RhoC and consequently the activation of downstream target molecules involve in the signaling cascade. For this reason we investigated the role of miR-138 in HNSCC. METHODS In vitro studies were carried out to evaluate the role of miR-138 in HNSCC cell lines and in primary tumors obtained from HNSCC patients. Real time RT-PCR, Western blot, cell motility, invasion and colony formation assays were performed according to standard procedures. RESULTS Data obtained by G-LISA and real time PCR shows an inverse correlation between RhoC expression and miR-138 in HNSCC cell lines. Additionally, we obtained a similar pattern of RhoC and miR-138 expression in primary tumors from HNSCC patients. Over expression of miR-138 in HNSCC lines showed down regulation of RhoC, as well as a decrease in cell motility, invasion colony and stress fiber formation. Furthermore, a significant down regulation was observed for FAK, Src and Erk(1/2) upon miR-138 overexpression. CONCLUSION These findings strongly suggest that the inhibition of RhoC can be achieved by over expressing miR-138, which further attenuates the downstream signaling cascade leading to cancer progression and survival. Moreover, this study for the first time shows that down regulation of FAK, Src and Erk(1/2) by miR-138 overexpression is due to inhibition of RhoC in HNSCC.

Abstract
Objectives A cross-sectional epidemiological study explored genetic susceptibility to oral precancer and cancer in Puerto Rico (PR). Materials and Methods Three hundred three individuals with a benign oral condition, oral precancer (oral epithelial hyperplasia/hyperkeratosis, oral epithelial dysplasia), or oral squamous cell carcinoma (SCCA) were identified via PR pathology laboratories. A standardized, structured questionnaire obtained information on epidemiological variables; buccal cells were collected for genetic analysis. Genotyping was performed using Taqman® assays. Allelic frequencies of single nucleotide polymorphisms (SNPs) were evaluated in cytokine genes and genes influencing tumor metastasis. Risk estimates for a diagnosis of oral precancer or SCCA while having a variant allele were generated using logistic regression. Adjusted models controlled for age, gender, ancestry, education, smoking and alcohol consumption. Results Relative to persons with a benign oral lesion, individuals with homozygous recessive allelic variants of tumor necrosis factor (TNF-α) −238 A/G SNP had a reduced odds of having an oral precancer (ORadjusted = 0.15; 95% CI 0.03–0.70). The transforming growth factor beta-1 (TGFβ-1 −509 C/T) polymorphism was inversely associated with having an oral SCCA among persons homozygous for the recessive variant (ORcrude = 0.27; 95% CI 0.09–0.79). The matrix metalloproteinase gene (MMP-1) variant, rs5854, was associated with oral SCCA; participants with even one variant allele were more likely to have oral SCCA (ORadjusted = 2.62, 95% CI 1.05–6.53) compared to people with ancestral alleles. Conclusion Our exploratory analyses suggest that genetic alterations in immune system genes and genes with metastatic potential are associated with oral precancer and SCCA risk in PR.

Abstract
microRNAs (miRs) are small noncoding single-stranded RNAs, about 19–25 nucleotides long. They have been shown to be capable of altering mRNA expression; thus some are oncogenic or tumour suppressive in nature and are regulated by cellular and epigenetic factors. The molecular pathogenic pathway of many cancers has been modified since the discovery of miRs. Head and neck squamous cell carcinoma (HNSCC), the sixth most common cancer in the world, has recently been associated with infection by the human papillomavirus (HPV). miR expression profiles are altered in the transition from dysplasia to carcinoma, with some changes being specific to the underlying risk factor. This difference is particularly significant in HPV-positive HNSCC where host miRs are modulated by the virus, creating a different profile to HPV-negative HNSCC. Saliva, as an easily collected proximal biofluid containing numerous miRs, presents an attractive noninvasive diagnostic tool in detecting HNSCC and determining prognosis. Furthermore, miRs may play a role in the analysis of surgical margins for residual tumour extension and in the development of novel miR-based therapeutic targets and agents.

Abstract
BACKGROUND Increased expression of microRNAs (miRNAs), miR-21, miR-345, and miR-181b has been demonstrated in oral leukoplakia (OL) that progresses to oral squamous cell carcinoma (OSCC), suggesting a miRNA signature with potential prognostic value. On the basis of these findings, this pilot study aimed to investigate the cytological and histopathological features that are used to grade oral dysplasia and determine associations with the expression of these 3 potentially cancer-related miRNAs. We also compared the expression levels of these miRNAs in OL with normal oral mucosa and OSCC. METHODS We evaluated miRNA expression by qPCR in 22 samples of OL demonstrating different grades of dysplasia, as well as 17 cases of OSCC, and 6 samples of normal oral mucosa. We associated the miRNAs expression profiles with cytological and histopathological features of OL. RESULTS OSCC cases showed increased expression of all 3 miRNAs when compared with OL and normal oral mucosa. Increased expression of miR-21 was also observed in OL when compared with normal oral mucosa. We found a higher expression of miR-21 and miR-181b in OL that presented with an increased number of mitotic figures, increased nuclear/cytoplasmic ratio, or hyperchromasia. Increased expression of miR-21 was also detected in OL with abnormally superficial mitosis. Higher expression of miR-345 was observed in OL with an increased number and size of nucleoli or increased nuclear/cytoplasmic ratio. CONCLUSIONS In conclusion, the present study shows that some cytological and histopathological parameters used to grade dysplasia are associated with altered miRNA expression.

Abstract
BACKGROUND AND PURPOSE Betel nut chewing is associated with oral cavity cancer in Taiwan. OC3 is an oral carcinoma cell line that was established from cells collected from a long-term betel nut chewer who does not smoke. After we found that microRNA-17-5p (miR-17-5p) is induced in OC3 cells, we used this cell line to examine the biological role(s) of this microRNA in response to exposure to ionizing radiation. MATERIALS AND METHODS A combined SYBR green-based real-time PCR and oligonucleotide ligation assay was used to examine the expression of the miR-17 polycistron in irradiated OC3 cells. The roles of miR-17-5p and p21 were evaluated with specific antisense oligonucleotides (ODN) that were designed and used to inhibit their expression. Expression of the p21 protein was evaluated by Western blotting. The clonogenic assay and annexin V staining were used to evaluate cell survival and apoptosis, respectively. Cells in which miR-17-5p was stably knocked down were used to create ectopic xenografts to evaluate in vivo the role of miR-17-5p. RESULTS A radiation dose of 5 Gy significantly increased miR-17-5p expression in irradiated OC3 cells. Inhibition of miR-17-5p expression enhanced the radiosensitivity of the OC3 cells. We found that miR-17-5p downregulates radiation-induced p21 expression in OC3 cells and, by using a tumor xenograft model, it was found that p21 plays a critical role in increasing the radiosensitivity of OC3 cells in vitro and in vivo. CONCLUSION miR-17-5p is induced in irradiated OC3 cells and it downregulates p21 protein expression, contributing to the radioresistance of OC3 cells.

MicroRNA-17/20a functions to inhibit cell migration and can be used a prognostic marker in oral squamous cell carcinoma. Oral Oncol 2013; 49:923-931.

Abstract
OBJECTIVES Oral squamous cell carcinoma (OSCC) accounts for>90% oral cancer which is a leading cause of cancer death worldwide. Early diagnosis may well offer an opportunity to increase survival to this neoplasm. Micro(mi)RNA-interfered cancer progression is crucial, yet its migration machinery of OSCC is still unknown. To access whether the possible miRNA prognostic markers and underlying mechanisms, we developed a highly migratory TW2.6 MS-10 cells from TW2.6 cells to investigate the issue. MATERIALS AND METHODS miRNA profiling was performed on TW2.6 and TW2.6 MS-10. Target miRNA was correlated to pathological status in OSCC patients by real-time RT-PCR. A downstream effector was identified using a bioinformatics analysis, and a 3'-untranslated region (UTR) reporter assay was used. RESULTS An miRNA cluster, miR-17-92, including miR-17, miR-19b, miR-20a, and miR-92a, was found to be significantly down-regulated in TW2.6 MS-10 compared to TW2.6 cells. Overexpression of this cluster decreased the migratory ability of OSCC cell lines. We further demonstrated that miR-17 and miR-20a are the main miRNAs of miR-17-92 cluster which modulate OSCC migration. Clinically, miR-17/20a showed negative correlation with TNM stage and lymphatic metastasis. Through a bioinformatics screening analysis and 3'UTR reporter assay, we confirmed the integrin (ITG) β8 as a direct target of miR-17/20a, and knockdown of ITGβ8 reduced cell migratory capability of OSCC. CONCLUSIONS miR-17/20a acts as a prognostic predictor of OSCC patients' outcome and a tumor migration suppressor miRNA.

Abstract
We combined an iTRAQ-based quantitative proteomic analysis and the miRNA determination to profile potentially novel biomarker from oral cancer. There are 757 and 674 unique proteins identified from proteomic analysis, and 13 proteins displayed consistent underexpression (<0.67 fold) in normal tissues in comparison with the corresponding tumor tissues. After preliminary screening, EGFR, OAT, TPT1, ITGA6, G3BP1 and CB39L were the six genes validated in the 37 oral cancer patients (T1, n=10; T2, n=10; T3, n=10 and T4, n=7). The TPT1, ITGA6 and CAB39L genes were displayed the higher transcriptions level in the tumor tissues and the TPT1, ITGA6 and CAB39L proteins were also shown overexpression in the tumor tissues from the same patients. The miR-19a, 19b, 27a, 27b, 186, 203 and 377 transcripts were predicted and the miR-27b level was shown to significantly reduce in the tumor tissues and the plasma of OSCC patients. In the in vitro study, the overexpression of miR-27b only significantly decreased TCTP protein and gene levels in both HSC-3 and Cal-27 cell lines. Our results demonstrate that human miR-27b regulates the expression of the TCTP tumor protein, and circulating miR-27b may be useful as a biomarker for oral cancer research.

Abstract
Head and neck squamous cell carcinomas (SCCHN) arise in the mucosa of the upper aerodigestive tract at multiple anatomic sites. While tobacco and alcohol exposure remain the primary risk factors for this malignancy, infection with the human papilloma virus is emerging as a major contributing factor to cancers that arise primarily in the oropharynx. Despite therapeutic advances, survival has remained relatively unchanged over the past few decades. Increased understand of the cellular and molecular biology of these cancers will improve our understanding of this malignancy and facilitate the development of more effective therapeutic strategies. Alterations that have been studied to date include genetic and epigenetic changes. While the epidermal growth factor receptor (EGFR) is the only established molecular therapeutic target, other proteins and pathways are under active investigation to determine their contribution to SCCHN carcinogenesis and progression.

Abstract
Background MicroRNA (miRNA) expression is broadly altered in cancer, but few studies have investigated miRNA deregulation in oral squamous cell carcinoma (OSCC). Epigenetic mechanisms are involved in the regulation of >30 miRNA genes in a range of tissues, and we aimed to investigate this further in OSCC. Methods TaqMan® qRT-PCR arrays and individual assays were used to profile miRNA expression in a panel of 25 tumors with matched adjacent tissues from patients with OSCC, and 8 control paired oral stroma and epithelium from healthy volunteers. Associated DNA methylation changes of candidate epigenetically deregulated miRNA genes were measured in the same samples using the MassArray® mass spectrometry platform. MiRNA expression and DNA methylation changes were also investigated in FACS sorted CD44high oral cancer stem cells from primary tumor samples (CSCs), and in oral rinse and saliva from 15 OSCC patients and 7 healthy volunteers. Results MiRNA expression patterns were consistent in healthy oral epithelium and stroma, but broadly altered in both tumor and adjacent tissue from OSCC patients. MiR-375 is repressed and miR-127 activated in OSCC, and we confirm previous reports of miR-137 hypermethylation in oral cancer. The miR-200 s/miR-205 were epigenetically activated in tumors vs normal tissues, but repressed in the absence of DNA hypermethylation specifically in CD44high oral CSCs. Aberrant miR-375 and miR-200a expression and miR-200c-141 methylation could be detected in and distinguish OSCC patient oral rinse and saliva from healthy volunteers, suggesting a potential clinical application for OSCC specific miRNA signatures in oral fluids. Conclusions MiRNA expression and DNA methylation changes are a common event in OSCC, and we suggest miR-375, miR-127, miR-137, the miR-200 family and miR-205 as promising candidates for future investigations. Although overall activated in OSCC, miR-200/miR-205 suppression in oral CSCs indicate that cell specific silencing of these miRNAs may drive tumor expansion and progression.

Abstract
Oral epithelial dysplasias are believed to progress through a series of histopathological stages; from mild to severe dysplasia, to carcinoma in situ, and finally to invasive OSCC. Underlying this change in histopathological grade are gross chromosome alterations and changes in gene expression of both protein-coding genes and non-coding RNAs. Recent papers have described associations of aberrant expression of microRNAs, one class of non-coding RNAs, with oral cancer. However, expression profiling of long non-coding RNAs (lncRNAs) has not been reported. Long non-coding RNAs are a novel class of mRNA-like transcripts with no protein coding capacity, but with a variety of functions including roles in epigenetics and gene regulation. In recent reports, the aberrant expression of lncRNAs has been associated with human cancers, suggesting a critical role in tumorigenesis. Here, we present the first long non-coding RNA expression map for the human oral mucosa. We describe the expression of 325 long non-coding RNAs, suggesting lncRNA expression contributes significantly to the oral transcriptome. Intriguingly, ∼60% of the detected lncRNAs show aberrant expression in oral premalignant lesions. A number of these lncRNAs have been previously associated with other human cancers.

Abstract
Micro-ribonucleic acids (microRNAs) are small molecules containing 20-23 nucleotides. Despite their small size, it is likely that almost every cellular process is regulated by them. Moreover, aberrant microRNA expression has been involved in the development of various diseases, including cancer. Although many data are available about the role of microRNAs in various lymphoproliferative disorders, their impact on the development of acute lymphoblastic leukemia of T-cell progenitors is largely unknown. In this review, we present recent information about how specific microRNAs are expressed and regulated during malignant T-lymphopoiesis and about their role during normal hematopoiesis.

Abstract
MicroRNAs (miRNAs) are small, noncoding RNAs which regulate cell differentiation, proliferation, development, cell cycle, and apoptosis. Expression profiling of miRNAs has been performed and the data show that some miRNAs are upregulated or downregulated in cancer. Several studies suggest that the expression profiles of miRNAs are associated with clinical outcomes. However, the set of miRNAs with altered expressing differs depending on the type of cancer, suggesting that it is important to understand which miRNAs are related to which cancers. Therefore, this review aimed to discuss potentially crucial miRNAs in head and neck squamous cell carcinoma (HNSCC) and oral squamous cell carcinoma (OSCC).

Abstract
MicroRNAs (miRNAs) play important roles in neoplastic process. miR-24 is localized on chromosome 9q22 and 19p13, regions frequently altered in oral squamous cell carcinoma (OSCC). This study showed that miR-24 was up-regulated in OSCC tissues relative to control samples. In addition, the plasma levels of miR-24 in OSCC patients were significantly higher than in control individuals. miR-24 expression was also higher in OSCC cell lines relative to normal oral keratinocytes. Experiments blocking miR-24 and using exogenous miR-24 expression indicated that miR-24 contributes to the growth of OSCC cells and that miR-24 may target p57. This study suggests that miR-24 is involved in the regulation of OSCC growth and that the miR-24's level in plasma may be validatable as a tumor marker for OSCC patients.

Abstract
MicroRNAs (miRNAs) mir15a and let7a are important regulators of bcl-2, ras and c-myc proteins. Considering that these miRNAs are commonly altered in many human cancers and that these proteins are reported to be altered in oral squamous cell carcinoma (OSCC), we investigated them in a set of OSCC cases. The miRNAs as well as the proteins were evaluated in the tumor and blood of 20 patients by real-time quantitative PCR and immunohistochemistry, respectively. The expression of mir15a and bcl-2 proteins in the tumors was not associated with each other or with tumor staging. On the other hand, we found reduced expression of this miRNA in the blood of patients with an advanced stage of OSCC and with lymph node metastasis. The expression of let7a in the tumor and blood was not associated with tumor size, lymph node metastasis, tumor staging and immunoexpression of ras and c-myc proteins. In conclusion, the present study shows that reduced expression of mir15a is associated with OSCC staging.
