Abstract
BACKGROUND/AIM MicroRNAs (miRNAs) are abnormally expressed and involved in the pathogenesis of various carcinomas. The present study aimed to identify novel miRNA genes associated with the pathogenesis and prognosis of oesophageal squamous cell carcinoma (ESCC). MATERIALS AND METHODS The miRNA profiling of 873 genes was performed using surgically resected oesophageal tissues from 35 patients with ESCC to identify candidate miRNAs. To examine the biological activities of candidate miRNAs, their proliferative, invasive, and migratory abilities were evaluated in ESCC cells subjected to miRNA mimic-mediated over-expression. The miRNA expression levels of the selected candidate miRNAs were analysed in the resected oesophageal tissues of 76 patients with ESCC from the two cohorts and correlated with the clinicopathological parameters. RESULTS Among the four candidate miRNAs identified by miRNA profiling, miR-877-3p was selected for subsequent analyses. In vitro analyses showed that the over-expression of miR-877-3p significantly suppressed the proliferation, invasion, and migration of ESCC cell lines compared with those of control cells. In the analyses of clinical specimens, the expression of miR-877-3p was down-regulated in ESCC tissues compared with that in adjacent normal oesophageal tissues. The down-regulation of miR-877-3p expression in ESCC tissues was significantly associated with advanced local progression and lymphatic involvement. The miR-877-3p down-regulation was also significantly associated with poor disease-free and disease-specific survival. CONCLUSION miR-877-3p acts as a tumour suppressor gene in ESCC cells, and its down-regulation in ESCC tissues is associated with a poor prognosis. Thus, miR-877-3p may serve as a novel prognostic marker and promising therapeutic target.

Abstract
Osteosarcoma (OS) is the most common high-grade malignant bone tumor in teenagers. MicroRNAs can function as posttranscriptional regulators of gene expression, playing critical roles in cancer dev-877-3p in OS. Quantitative real-time RT-PCR was carried out for detecting miR-877-3p expression in OS. The effects of miR-877-3p on proliferation was analyzed via MTT, colony formation, and flow cytometry assays. Angiogenesis of endothelial cells were investigated by wound healing and tube formation assay. Gene profiling based on PCR array and luciferase reporter assay were conducted to determine target genes of miR-877-3p. In-vivo study was used to determine the effects of miR-877-3p on the tumor growth. The expression of miR-877-3p was markedly downregulated in OS tissues and cell lines. Low expression of miR-877-3p predicts poor prognosis of OS patients. miR-877-3p overexpression was found to inhibit the proliferation of OS cell lines. The angiogenesis assays showed that miR-877-3p attenuated the angiogenesis. Further mechanism studies showed that miR-877-3p can reduce (Fibroblast Growth Factor 2) FGF2 expression in OS cells by binding to the 3’UTR end of FGF2. Moreover, increased expression of miR-877-3p was responsible for the inhibition of tumor growth and angiogenesis. Taken together, our findings indicated that miR-877-3p might exhibit tumor suppressive role by targeting FGF2 signaling, which may serve as potential target for OS.

Abstract
We aimed to investigate the effect of methotrexate (MTX) on microRNA modulation in rheumatoid arthritis fibroblast-like synovial cells (RA-FLS). RA-FLS were treated with MTX for 48 h. We then performed miRNA array analysis to investigate differentially expressed miRNAs. Transfection with miR-877-3p precursor and inhibitor were used to investigate the functional role of miR-877-3p in RA-FLS. Gene ontology analysis was used to investigate the cellular processes involving miR-877-3p. The production of cytokines/chemokines was screened by multiplex cytokine/chemokine bead assay and confirmed by ELISA and quantitative real-time PCR. The migratory and proliferative activities of RA-FLS were analyzed by wound healing assay and MKI-67 expression. MTX treatment altered the expression of 13 miRNAs (seven were upregulated and six were downregulated). Among them, quantitative real-time PCR confirmed that miR-877-3p was upregulated in response to MTX (1.79 ± 0.46-fold, p < 0.05). The possible target genes of miR-877-3p in RA-FLS revealed by the microarray analysis were correlated with biological processes. The overexpression of miR-877-3p decreased the production of GM-CSF and CCL3, and the overexpression of miR-877-3p inhibited migratory and proliferative activity. MTX altered the miR-877-3p expression on RA-FLS, and this alteration of miR-877-3p attenuated the abundant production of cytokines/chemokines and proliferative property of RA-FLS.

Abstract
Esophageal squamous cell carcinoma (ESCC) represents one of the most common malignancies and is the fifth leading cause of cancer-related deaths. Long intergenic non-coding RNAs (lincRNAs) have been suggested to be dysregulated in various types of cancers, and a growing number of lincRNAs have been implicated to be functional in the ESCC progression. In this study, we examined the role of linc00941 in the ESCC progression and explored the underlying molecular mechanisms. The bioinformatics analysis identified the up-regulation of linc00941 in the ESCC tissues. Further in vitro studies showed that linc00941 was up-regulated in ESCC cell lines. The loss-of-function studies demonstrated that linc00941 knockdown suppressed ESCC cell proliferation, invasion and migration, and also suppressed the in vivo tumor growth. Furthermore, bioinformatics prediction along with luciferase reporter assay and RNA immunoprecipitation assay implied that linc00941 acted as a competing endogenous RNA for miR-877-3p, and linc00941 regulated ESCC cell progression via at least targeting miR-877-3p. Subsequently, miR-877-3p targeted prostate transmembrane protein, androgen induced 1 (PMEPA1) 3' untranslated region and repressed PMEPA1 expression in ESCC cells; overexpression of PMEPA1 attenuated the inhibitory effects of linc00941 knockdown on the ESCC cell progression. Linc00941 knockdown suppressed epithelial-mesenchymal transition (EMT) via targeting miR-877-3p/PMEPA1 axis in ESCC cells. In conclusion, our results indicated the oncogenic role of linc00941 in ESCC, and knockdown of linc00941 suppressed ESCC cell proliferation, invasion, migration and EMT via interacting with miR-877-3p/PMEPA1 axis.

Abstract
No therapeutic targets and molecular biomarkers are available in cervical cancer (CC) management. In other cancer types, micro-RNA-877-3p (miR-877-3p) has been associated with events relevant for CC development. Thus, we aimed to determine miR-877-3p role in CC. miR-877-3p levels were examined by quantitative-PCR in 117 cervical lesions and tumors. Effects on CC cell proliferation, migration, and invasion were evaluated upon anti-miR-877-3p transfection. miR-877-3p dependent molecular mechanism was comprehensively explored by proteomics, dual-luciferase reporter assay, western blot, and immunohistochemistry. Cervical tumors expressed higher miR-877-3p levels than benign lesions. miR-877-3p promoted CC cell migration and invasion, at least partly by modulating cytoskeletal protein folding through the chaperonin-containing T-complex protein 1 complex. Notably, miR-877-3p silencing synergized with paclitaxel. Interestingly, miR-877-3p downregulated the levels of an in silico-predicted target, ZNF177, whose expression and subcellular location significantly distinguished high-grade squamous intraepithelial lesions (HSILs) and squamous cell carcinomas of the cervix (SCCCs). Cytoplasmic ZNF177 was significantly associated with worse progression-free survival in SCCC. Our results suggest that: (i) miR-877-3p is a potential therapeutic target whose inhibition improves paclitaxel effects; (ii) the expression and location of its target ZNF177 could be diagnostic biomarkers between HSIL and SCCC; and (iii) cytoplasmic ZNF177 is a poor-prognosis biomarker in SCCC.

Abstract
Our previous study showed that the lncRNA UBE2R2-AS1 inhibits the growth and invasion of glioma cells and promotes apoptosis through the miR-877-3p/TLR4 pathway. In this study, it was further found that the expression of UBE2R2-AS1 in glioma tissues was decreased significantly, and gradually decreased with increasing clinical stage. Chi-square analysis showed that the expression of UBE2R2-AS1 was significantly correlated with the WHO stage of tumor and epilepsy. Using Kaplan-Meier univariate survival analysis, it was found that the expression of UBE2R2-AS1 correlated positively with the overall survival of patients with glioma, while multiple Cox regression analysis showed that the expression of UBE2R2-AS1 correlated positively with the overall survival of patients with glioma as a protective factor for glioma prognosis. The analysis of data from TCGA also showed that patients with high UBE2R2-AS1 levels or low miR-877-3p expression were more likely to have good survival outcomes. Further construction of a glioma xenograft model in nude mice showed that UBE2R2-AS1 overexpression inhibited the growth of tumors, and the inhibition of miR-877-3p expression had a similar effect. Simultaneous UBE2R2-AS1 overexpression and miR-877-3p inhibition further decreased the growth rate of tumors in nude mice. Taken together, the results of our study suggest that UBE2R2-AS1 is an important tumor suppressor gene in glioma, which may be a good marker and treatment target for the clinical detection of glioma.

Abstract
Background Long non-coding RNAs (LncRNAs) are dysregulated in multiple human cancers and they are highly involved in tumor progression. Previous studies have identified the oncogenic lncRNA HOXD cluster antisense RNA 1 (HOXD-AS1) in human cancers, while its roles in cervical cancer (CC) remain unclear. Herein we intended to characterize the implication of HOXD-AS1 in CC. Methods qRT-PCR was applied to examine the relative expression of HOXD-AS1 in CC tissues, cell lines and transfected cells. Wound healing and transwell assays were applied to detect cell migration and invasion alteration. The targeting relationship between miRNA and mRNA/lncRNA was determined by dual luciferase reporter, qRT-PCR and western blot assays. Results HOXD-AS1 was overexpressed in CC tissues and cell lines. Its higher level predicted worse prognosis of CC patients. SiRNA mediated knockdown of HOXD-AS1 repressed CC cell migration and invasion, and its overexpression did the opposite. Mechanistically, HOXD-AS1 acted as a competing endogenous RNA (ceRNA) to sponge miR-877-3p and led to upregulation of FGF2, a target of miR-877-3p. Importantly, either miR-877-3p overexpression or FGF2 inhibition could abolish the migration and invasion promotion induced by HOXD-AS1. Conclusion HOXD-AS1 functions as a tumor-promoting lncRNA via the miR-877-3p/FGF2 axis in CC. HOXD-AS1 might be a promising therapeutic target as well as a novel prognostic biomarker for CC.

Abstract
Ischemic cardiac disease is the leading cause of morbidity and mortality in the world. Despite the great efforts and progress in cardiac research, the current treatment of cardiac ischemia reperfusion injury (I/RI) is still far from being satisfactory. This study was performed to investigate the role of long non-coding RNA (lncRNA) H19 in regulating myocardial I/RI. We found that H19 expression was downregulated in the I/R hearts of mice and cardiomyocytes treated with H2O2. Overexpression of H19 alleviated myocardial I/RI of mice and cardiomyocyte injury induced by H2O2. We found that H19 functioned as a competing endogenous RNA of miR-877-3p, which decreased the expression of miR-877-3p through the base-pairing mechanism. In parallel, miR-877-3p was upregulated in H2O2-treated cardiomyocytes and mouse ischemia reperfusion (I/R) hearts. miR-877-3p exacerbated myocardial I/RI and cardiomyocyte apoptosis. We further established Bcl-2 as a downstream target of miR-877-3p. miR-877-3p inhibited the mRNA and protein expression of Bcl-2. Furthermore, H19 decreased the Bcl-2/Bax ratio at mRNA and protein levels, cytochrome c release, and activation of caspase-9 and caspase-3 in myocardial I/RI mice, which were canceled by miR-877-3p. In summary, the H19/miR-877-3p/Bcl-2 pathway is involved in regulation of mitochondrial apoptosis during myocardial I/RI, which provided new insight into molecular mechanisms underlying regulation of myocardial I/RI.

Abstract
MicroRNAs (miRNAs) are emerging as important regulators of various physiological and pathological processes and may serve key roles in the maintenance of bone homeostasis via effects on osteoblast differentiation. The aim of the present study was to define the role of miR-877-3p in osteoblast differentiation using MC3T3-E1 cells, an osteoblast precursor cell line. It was demonstrated using RT-qPCR analysis that miR-877-3p was gradually increased in MC3T3-E1 cells during the osteoblastic differentiation induced by transforming growth factor (TGF)-β1. Gain-of-function and loss-of-function experiments revealed that the overexpression of miR-877-3p promoted the osteoblastic differentiation of MC3T3-E1 cells, whereas depletion of miR-877-3p inhibited this process in vitro and in vivo. Bioinformatics analysis and validation experiments demonstrated that Smad7, which acts as a negative regulator of osteogenesis, was a target of miR-877-3p. Furthermore, the overexpression of Smad7 partially reversed the osteoblastic differentiation of MC3T3-E1 cells induced by miR-877-3p. In conclusion, the results of the present study suggest that the miR-877-3p/Smad7 axis is associated with the osteoblastic differentiation of MC3T3-E1 cells and may indicate a potential therapeutic approach for osteogenesis disorders.
