Abstract
Background Pancreatic cancer is a common cancer with a poor prognosis and an increasing morbidity. miR-19b-3p has been implicated in some cancers, however, its role in pancreatic cancer is unclear. Methods Human pancreatic cancer cell line Capan-2 cells were transfected with miR-19b-3p mimic and inhibitor. Cell proliferation was measured by 5-Ethynyl-2'-deoxyuridine (EdU) staining assays. Cell cycle of Capan-2 cells was examined by flow cytometry. The expression of phosphatase and tension homolog (PTEN) was determined by real-time quantitative polymerase chain reaction (PCR) and western blotting analysis. Functional rescue experiments were performed through PTEN overexpression and miR-19b-3p mimic by using EdU staining assays. Results miR-19b-3p mimic significantly increased miR-19b-3p while miR-19b-3p inhibitor decreased that. EdU staining showed that miR-19b-3p overexpression promoted Capan-2 cells proliferation while miR-19b-3p inhibition decreased that. Flow cytometry analysis of cell cycle indicated that miR-19b-3p overexpression increased the percentage of Capan-2 cells in S phase while miR-19b-3p inhibition decreased that. PTEN was confirmed to be a target gene of miR-19b-3p and PTEN overexpression eliminated the pro-proliferation effects of miR-19b-3p in Capan-2 cells. Conclusions Our study demonstrates that miR-19b-3p promotes Capan-2 cells proliferation by targeting PTEN.

Abstract
BACKGROUND Nasopharyngeal cancer (NPC), despite being one of the most malignant head and neck carcinomas (HNC), lacks comprehensive prognostic biomarkers that predict patient survival. Therefore, this systematic review and meta-analysis is aimed to evaluate the potential prognostic value of miRNAs as prognostic biomarkers in NPC. METHODS PRISMA guidelines were used to conduct this systematic review and meta-analysis study. Permutations of multiple "search key-words" were used for the search strategy, which was limited to articles published between January 2012 and March 2018. The retrieved articles were meticulously searched with multi-level screening by two reviewers and confirmed by other reviewers. Meta-analysis was performed using Hazard Ratios (HR) and associated 95% Confidence Interval (CI) of survival obtained from previously published studies. Publication bias was assessed by Egger's bias indicator test and funnel plot symmetry. RESULTS A total of 5069 patients across 21 studies were considered eligible for inclusion in the systematic review, with 65 miRNAs being evaluated in the subsequent meta-analysis. Most articles included in this study originated from China and one study from North Africa. The forest plot was generated using cumulated survival data, resulting in a pooled HR value of 1.196 (95% CI: 0.893-1.601) indicating that the upregulated miRNAs increased the likelihood of death of NPC patients by 19%. CONCLUSION To our knowledge, this is the first meta-analysis that examines the prognostic effectiveness of miRNAs as biomarkers in NPC patients. We noted that the combined effect estimate of HR across multiple studies indicated that increased miRNA expression in NPC potentially leads to poor overall survival. However, further large-scale prospective studies on the clinical significance of the miRNAs, with sizable cohorts are necessary in order to obtain conclusive results.

Abstract
PURPOSE Radioresistance is an important factor for unsatisfactory prognosis in Nasopharyngeal carcinoma (NPC) patients. Ubiquitous mitochondrial creatine kinase (CKMT1) is always associated with malignancy in a variety of cancers. However, its significance in NPC progression and radiosensitivity remains unclear. The present study focused on investigating the effects of CKMT1 on NPC cell radiosensitivity. MATERIAL AND METHODS CKMT1 was overexpressed in NPC cell line CNE-1 or knocked out in CNE-2. Biological changes were detected after cells exposing to different doses of X-ray to determine the role of CKMT1 on NPC cell radiosensitivity. RESULTS CKMT1 promotes proliferation and migration in NPC cell lines CNE-1 and CNE-2. Overexpression of CKMT1 in CNE-1 cells enhanced colony formation rates, reduced G2/M phase cell cycle arrest, lowered apoptosis rate and c-PARP level, and elevated STAT3 phosphorylation level after radiation treatment. While knocking out CKMT1 using the CRISPR/Cas9 system in CNE-2 cells lowered colony formation rates, increased G2/M phase cell cycle arrest, apoptosis rates, and c-PARP levels, and decreased STAT3 phosphorylation in response to radiation treatment. CONCLUSIONS NPC cells with higher CKMT1 exhibited lower radiosensitivity through promoting phosphorylation of STAT3. Our findings suggest that CKMT1 may be an alternative radiotherapeutic target in NPC therapy.

Abstract
MicroRNAs have been reported to play a vital role in diverse biological processes and tumorigenesis. MicroRNA-19b-5p has been observed to be downregulated in other cancers, but the function of microRNA-19b-5p in human nasopharyngeal carcinoma has not been well investigated. In our study, these results demonstrated that microRNA-19b-5p was significantly downregulated in 37 pairs of nasopharyngeal carcinoma tissues when compared to normal tissues. Enforced expression of microRNA-19b-5p inhibited activity of cell proliferation and cell migration of nasopharyngeal carcinoma cancer cells, CNE1 and HNE1. Furthermore, microRNA-19b-5p targeted KRAS proto-oncogene, GTPase in cancer cells. In human clinical specimens, KRAS was higher expressed in cancer tissues when compared with normal tissues, which was inversely correlated with the expression of microRNA-19b-5p. More interestingly, microRNA-19b-5p sensitizes CNE1 cells to cisplatin by inhibiting its target KRAS. Finally, microRNA-19b-5p inhibits tumorigenesis in vivo. Thus, our results investigated that microRNA-19b-5p functioned as a tumor suppressor and indicated its potential application for the treatment of human nasopharyngeal carcinoma in future.

Abstract
Background In view of the limited knowledge of plasma biomarkers relating to cancer resistance to radiotherapy, we have set up screening, training and testing stages to investigate the microRNAs (miRNAs) expression profile in plasma to predict between the poor responsive and responsive groups after 6 months of radiotherapy. Methods Plasma was collected prior to and after radiotherapy, and the microRNA profiles were analyzed by quantitative reverse transcription polymerase chain reaction (qRT-PCR) arrays. Candidate miRNAs were validated by single qRT-PCR assays from the training and testing set. The classifier for ancillary prognosis was developed by multiple logistic regression analysis to correlate the ratios of miRNAs expression levels with clinical data. Results We revealed that eight miRNAs expressions had significant changes after radiotherapy and the expression levels of miR-374a-5p, miR-342-5p and miR-519d-3p showed significant differences between the responsive and poor responsive groups in the pre-radiotherapy samples. The Kaplan–Meier curve analysis also showed that low miR-342-5p and miR-519d-3p expressions were associated with worse prognosis. Our results revealed two miRNA classifiers from the pre- and post-radiotherapy samples to predict radiotherapy response with area under curve values of 0.8923 and 0.9405. Conclusions The expression levels of miR-374a-5p, miR-342-5p and miR-519d-3p in plasma are associated with radiotherapy responses. Two miRNA classifiers could be developed as a potential non-invasive ancillary tool for predicting patient response to radiotherapy.

Abstract
BACKGROUND AND OBJECTIVE There is a high incidence of nasopharyngeal carcinoma (NPC), malignant head and neck tumors, in southern China. Radioresistance is the main cause affecting the efficacy of NPC treatments. The POLG gene particularly plays an important role in radiation-induced damage repair. In this study, the authors established RNAi CNE-1 and CNE-2 knockdown in two NPC cell lines to observe whether this gene affects the radiosensitivity of NPC cells. MATERIALS AND METHODS Four short hairpin RNA (shRNA) expression plasmids targeting POLG gene were constructed and transfected into the NPC cell lines CNE-1 and CNE-2. Screening was performed to evaluate the stable expression of cloned cells, which were named CNE-1/POLG-shRNA1, CNE-1/POLG-shRNA2, CNE-2/POLG-shRNA1, and CNE-2/POLG-shRNA2. The negative controls CNE-1/Neg-shRNA and CNE-2/Neg-shRNA were additionally used. The MTT method, flow cytometry, clone formation analysis, cell migration, and other experimental methods were employed to verify changes in the radiosensitivity of the NPC cells. RESULTS Fluorescent quantitative PCR and Western blot confirmed the downregulation of the PLOG gene through diminished PLOG messenger RNA and protein levels. Consequently, the authors report the stable knockdown of the POLG gene in an NPC model. Dose-dependent radiation exposure of POLG inhibited NPC cell growth and increased apoptosis compared with control cells (p < 0.01), as demonstrated through colony formation assay and flow cytometry. Functional assays indicated that knockdown of the POLG in CNE-1 and CNE-2 cells remarkably reduced cell viability and proliferation. Specifically, POLG knockdown led to G1 phase arrest and apoptosis. CONCLUSIONS Overall, the authors conclude that POLG downregulation alters the radiosensitivity of NPC cells, indicating that the gene is likely involved in conferring the radiation response of the cells. In addition, findings in this study suggest a novel role for POLG as a potential predictive marker for NPC radiotherapy efficiency. POLG gene can be used as a potential clinical target to effectively improve the radiosensitivity of NPC.

Abstract
BACKGROUND Radioresistance is a major factor leading to the failure of radiotherapy and poor prognosis in tumor patients. Following the application of radiotherapy, the activity of various metabolic pathways considerably changes, which may result in the development of resistance to radiation. MAIN BODY Here, we discussed the relationships between radioresistance and mitochondrial and glucose metabolic pathways, aiming to elucidate the interplay between the tumor cell metabolism and radiotherapy resistance. In this review, we additionally summarized the potential therapeutic targets in the metabolic pathways. SHORT CONCLUSION The aim of this review was to provide a theoretical basis and relevant references, which may lead to the improvement of the sensitivity of radiotherapy and prolong the survival of cancer patients.

Abstract
Background Recent studies have reported that microRNAs (miRNAs) often function as negative post-transcriptional regulators with altered expression levels found in colorectal cancer (CRC). There have been few studies on miRNAs that regulate the oncogenic alterations in CRC. Here, we aim to explore the anti-cancer miRNA and the potential mechanisms by which miRNAs modulate CRC progression. Methods We performed an integrated analysis of CRC miRNA expression datasets in The Cancer Genome Atlas (TCGA). The miRNA with the lowest expression, miR-760, was validated in an independent validation sample cohort of 76 CRC tissues. Functional assays, such as CCK-8 assay, colony formation assay, and CFSE staining, were used to determine the oncogenic role of miR-760 in human CRC progression. Furthermore, western blotting and dual-luciferase reporter assay were used to determine the mechanism by which miR-760 promotes proliferation of CRC cells. Xenograft nude mouse models were used to determine the role of miR-760 in CRC tumorigenicity in vivo. Immunohistochemical assays were conducted to study the relationship between miR-760 expression and basic leucine zipper transcriptional factor ATF-like 3 (BATF3) expression in human CRC samples. Results miR-760 was markedly downregulated in CRC tissues, and low miR-760 expression was associated with poor prognosis among CRC patients. Upregulation of miR-760 suppressed CRC cell proliferation, whereas downregulation of miR-760 promoted CRC proliferation in vitro. Additionally, we identified BATF3 as a direct target of miR-760, and that the essential biological function of miR-760 during CRC progression both in vitro and in vivo is to suppress the expression of BATF3 and downstream cyclinD1 via AP-1 transcription factor. Finally, we showed a significant correlation between miR-760 and BATF3 expression in CRC tissues. Conclusions miR-760 inhibited CRC growth by downregulating BATF3/AP-1/ cyclinD1 signaling.

Abstract
The aim of the present study was to investigate the expression and function of microRNA (miR)-371-5p in nasopharyngeal carcinoma (NPC). The levels of miR-371-5p were analyzed in nasopharyngeal epithelium tissues, NPC tissues, human NPC cell lines and NP69 cells using reverse transcription-quantitative polymerase chain reaction analysis. The association between the level of miR-371-5p and clinicopathological variables was also investigated. Cell proliferation was determined using an MTT assay, and the activities of cell metastasis were determined using wound healing and Transwell migration assays. To assess whether miR-371-5p can combine with the targeting sequence of B-cell lymphoma 2 (BCL2) mRNA or not, a luciferase activity assay was performed. An animal experiment was used to examine the effect of miR-371-5p on the development of NPC. The results revealed that the expression of miR-371-5p was reduced in NPC samples and NPC cells. The level of miR-371-5p was associated with clinical stage and distant metastasis in patients with NPC, and was inversely associated with the protein level of BCL-2 in NPC tissues. The upregulation of miR-371-5p reduced cell growth, migration and invasion, and inhibited carcinoma growth through targeting BCL2 mRNA. Taken together, the regulation of miR-371-5p was shown to offer potential as a novel treatment approach for NPC.

Abstract
Background In recent years, miR-152 has been dysregulated in a variety of tumors and used as a tumor suppressor. Nevertheless, its role in nasopharyngeal carcinoma (NPC) remains unidentified. Materials and methods Real-time quantitative PCR (polymerase chain reaction) was performed to analyze the expression of miR-152 in NPC cell lines. MiR-152 expression profiles in NPC tissues were obtained from Gene Expression Omnibus (GEO GSE36682). The effect of miR-152 on the invasion and proliferation of NPC cells was determined through cell invasion, wound healing, and cell viability assays. Apoptosis was examined by flow cytometry, and Western blot was performed to measure expression of the target gene. Pyrosequencing was used to detect the methylation level of NPC cells. Results In this study, miR-152 was downregulated in the NPC tissues and cell lines. When miR-152 was enhanced, the invasion and migration of NPC cells were inhibited. However, miR-152 had no effect on the proliferation of NPC cells. Luciferase reporter gene analysis was performed, and the results showed that DNMT1 (DNA (cytosine-5)-methyltransferase 1) is a direct target of miR-152 in NPC cells. DNMT1 downregulation and miR-152 overexpression both reversed the effects of miR-152 inhibition on the NPC cells. In addition, miR-152 expression increased as a result of the inhibition of the methylation level of miR-152 when DNMT1 expression was downregulated. Conclusion The overexpression of miR-152 inhibited the migration and invasion of NPC cells by targeting DNMT1. Furthermore, DNMT1 regulated miR-152 expression through DNA methylation. Overall, the novel miR-152-DNMT1 regulatory circuit may provide better understanding of the pathogenesis of NPC and new epigenetic therapeutic target in NPC.

Abstract
Nuclear factor kappa B (NF-κB) is a pluripotent and crucial dimer transcription factor that orchestrates various physiological and pathological processes, especially cell proliferation, inflammation, and cancer development and progression. NF-κB expression is transient and tightly regulated in normal cells, but it is activated in cancer cells. Recently, numerous studies have demonstrated microRNAs (miRNAs) play a vital role in the NF-κB signaling pathway and NF-κB-associated immune responses, radioresistance and drug resistance of cancer, some acting as inhibitors and the others as activators. Although it is still in infancy, targeting NF-κB or the NF-κB signaling pathway by miRNAs is becoming a promising strategy of cancer treatment.

Abstract
Radioresistance hampers success in the treatment of patients with advanced colorectal cancer (CRC). Improving our understanding of the underlying mechanisms of radioresistance could increase patients' response to irradiation (IR). MicroRNAs are a class of small RNAs involved in tumor therapy response to radiation. Here we found that miR-214 was markedly decreased in CRC cell lines and blood of CRC patients after IR exposure. Meanwhile, autophagy was enhanced in irradiated CRC cells. Mechanically, ATG12 was predicted and identified as a direct target of miR-214 by dual luciferase assay, qPCR, and Western blot. In vitro and in vivo experiments showed that miR-214 promoted radiosensitivity by inhibiting IR-induced autophagy. Restoration of ATG12 attenuated miR-214-mediated inhibition of cell growth and survival in response to IR. Importantly, miR-214 was highly expressed in radiosensitive CRC specimens and negatively correlated with plasma level of CEA. Moreover, ATG12 and LC3 expressions were increased in radioresistant CRC specimens. Our study elucidates that miR-214 promotes radiosensitivity by inhibition of ATG12-mediated autophagy in CRC. Importantly, miR-214 is a determinant of CRC irradiation response and may serve as a potential therapeutic target in CRC treatment.

Abstract
BACKGROUND Osteoarthritis (OA), as a degenerative disease, is a major problem in ageing populations. To better understand the underlying mechanisms in the pathogenesis of OA, this study was undertaken to investigate the role of microRNA (miR)-19a in chondrocytes. METHODS Expression of the members of miR-17-92 cluster in synovium from OA patients and non-OA patients were measured by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). miR-19a was abnormal expressed in human chondrocyte line (CHON-001 and T-C/28 cells) and primary human chondrocytes by transient transfection. Cell viability, migration and apoptosis were determined by CCK-8 assay, wound healing assay, and flow cytometry, respectively. Expression of apoptosis related factors was measured by western blot. Transcription factor SOX9 expression and activity of NF-κB pathway were also assessed by western blot. RESULTS Levels of miR-19a and other five members of miR-17-92 cluster were down-regulated in OA patients' synovium compare with non-OA. miR-19a overexpression promoted cell viability and migration of chondrocytes, while miR-19a suppression promoted cell apoptosis, and inhibited cell viability and migration. miR-19a direct up-regulated expression of SOX9, and thus affecting cell viability and migration. miR-19a promoted activation of NF-κB signaling pathway to up-regulate SOX9 expression. CONCLUSION miR-19a was down-regulated in synovium form OA patients. miR-19a could promote cell viability and migration of chondrocyte via positively regulating SOX9 expression through NF-κB signaling pathway. This study might provide the novel strategy for clinical treatment of OA caused by chondrocyte function degradation.

Abstract
The MID1 ubiquitin ligase activates mTOR signaling and regulates mRNA translation. Misregulation of MID1 expression is associated with various diseases including midline malformation syndromes, cancer and neurodegenerative diseases. While this indicates that MID1 expression must be tightly regulated to prevent disease states specific mechanisms involved have not been identified. We examined miRNAs to determine mechanisms that regulate MID1 expression. MicroRNAs (miRNA) are small non-coding RNAs that recognize specific sequences in their target mRNAs. Upon binding, miRNAs typically downregulate expression of these targets. Here, we identified four miRNAs, miR-19, miR-340, miR-374 and miR-542 that bind to the 3'-UTR of the MID1 mRNA. These miRNAs not only regulate MID1 expression but also mTOR signaling and translation of disease associated mRNAs and could therefore serve as potential drugs for future therapy development.

Abstract
Radiotherapy (RT) is a mainstay treatment for many types of cancer, although it is still a large challenge to enhance radiation damage to tumor tissue and reduce side effects to healthy tissue. Radiosensitizers are promising agents that enhance injury to tumor tissue by accelerating DNA damage and producing free radicals. Several strategies have been exploited to develop highly effective and low-toxicity radiosensitizers. In this review, we highlight recent progress on radiosensitizers, including small molecules, macromolecules, and nanomaterials. First, small molecules are reviewed based on free radicals, pseudosubstrates, and other mechanisms. Second, nanomaterials, such as nanometallic materials, especially gold-based materials that have flexible surface engineering and favorable kinetic properties, have emerged as promising radiosensitizers. Finally, emerging macromolecules have shown significant advantages in RT because these molecules can be combined with biological therapy as well as drug delivery. Further research on the mechanisms of radioresistance and multidisciplinary approaches will accelerate the development of radiosensitizers.

Abstract
The radioresistance of hepatocellular carcinoma (HCC) cells is a critical obstacle for effectively applying radiotherapy (RT) in HCC treatment. NF-κB, an important transcription factor, can influence critical cell fate decisions by promoting cell survival or anti-apoptosis in response to cell-stress, e.g. chemotherapies or ionizing radiation (IR). A20, also named as tumor necrosis factor α induced protein 3 (TNFAIP3), is a dominant negative regulator of NF-κB pathway and its functions in HCC are largely unknown. The present work aimed to reveal the role of A20 plays in affecting the radiosensitivity of HCC cells. Higher expression of A20 was detected in hepatic non-tumor cell line or clinical specimens compared with HCC cell lines or clinical specimens. A20 decreased the expression of proteins mediating cellular stress/injury response or epithelial-mesenchymal transition (EMT) process. Overexpression of A20 via adenovirus enhanced the effect of 60Co-γ ionizing radiation (IR) on HCC cells’ injury, e.g. G2/M arrest or DNA double strands break (DSB). Moreover, A20 also enhanced the in vitro or in vivo survival inhibiting of HCC cells induced by IR. These results reveal the roles of A20 in HCC radiosensitization and overexpression of A20 would be a novel strategy for HCC radiotherapy.

Abstract
Background LncRNA X inactive specific transcript (XIST) was reported to function as an oncogene in nasopharyngeal carcinoma cells (NPC) by sponging miR-34a-5p. However, the role of XIST in modulating the radiosensitivity of NPC cells and its mechanism still remain undefined. Material/Methods The expressions of XIST and miR-29c in NPC cells were evaluated by qRT-PCR. CNE1 and CNE2 cells were transfected with si-XIST, pcDNA-XIST, miR-29c mimics, anti-miR-29c, or respective controls by Lipofectamine 2000. The effects of XIST knockdown and miR-29c overexpression on cell proliferation, survival fraction, and γ-H2AX expression were investigated by CCK-8 assay, colony formation assay, immunofluorescence, and Western blot, respectively. Luciferase reporter assay and qRT-PCR analysis were performed to confirm whether XIST interacts with miR-29c and regulates its expression. Results XIST was upregulated and miR-29c was downregulated in NPC cells. The expressions of XIST and miR-29c changed reversely in response to irradiation. Knockdown of XIST and miR-29c overexpression both resulted in a dramatic suppression of cell proliferation, a marked enhancement of radiosensitivity, and an obvious increase of γ-H2AX foci formation in NPC cells. Luciferase reporter assay and qRT-PCR analysis demonstrated that XIST interacts with miR-29c and negatively regulates its expression. Moreover, miR-29c inhibition abrogated XIST knockdown-induced cell proliferation inhibition and radiosensitivity increase in NPC cells. Conclusions XIST knockdown suppressed cell proliferation and enhanced radiosensitivity of NPC cells by upregulating miR-29c, providing a novel therapeutic target to improve radiotherapy efficiency for patients with NPC.

MiR-203a-3p suppresses cell proliferation and metastasis through inhibiting LASP1 in nasopharyngeal carcinoma. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2017; 36:138. [PMID: 28982387 PMCID: PMC5629759 DOI: 10.1186/s13046-017-0604-3] [Citation(s) in RCA: 43] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/12/2017] [Accepted: 09/19/2017] [Indexed: 01/27/2023]
Abstract
BACKGROUND miR-203a-3p was reported as a tumor suppressor and disregulated in many malignancies including nasopharyngeal carcinoma (NPC). However, its function in tumor growth and metastasis in NPC has rarely been reported. METHODS The expression level of miR-203a-3p in human NPC tissues and cell lines was detected via real-time PCR (RT-PCR). Cell proliferation, migration and invasion were assessed in vitro by MTT, colony formation and transwell assay, respectively. The function of miR-203a-3p in vivo was detected through NPC xenograft tumor growth and lung metastatic mice model. Dual-luciferase reporter assay was used to identify the direct target of miR-203a-3p. RESULTS The expression of miR-203a-3p was decreased in NPC tissues and cell lines in comparison with normal nasopharyngeal tissues and cell line. Ectopic expression of miR-203a-3p inhibited while inhibiting miR-203a-3p expression increased NPC cell proliferation, migration and invasion in vitro. MR-203a-3p overexpression suppressed xenograft tumor growth and lung metastasis in vivo. LASP1 was identified as a direct target of miR-203a-3p, which was confirmed by real-time PCR and western blotting assay. Ectopic expression of LASP1 partially reversed miR-203a-3p-mediated inhibition on proliferation, migration and invasion in NPC cells. CONCLUSION Collectively, miR-203a-3p suppresses tumor growth and metastasis through targeting LASP1 in NPC. The newly identified miR-203a-3p/LASP1 pathway provides further insights into the initiation and progression of NPC, which may represent a novel therapeutic target for NPC.
