Abstract
microRNAs are a kind of endogenous, non-coding, single-strand small RNA. They have been reported as an important regulatory factor in skeletal myogenesis. In this study, miR-452 was selected from RNA high-throughput sequencing data to explore its regulatory role in myogenesis. Functionally, miR-452 overexpression could promote C2C12 myoblast proliferation while inhibiting myogenic differentiation. On the contrary, inhibition of miR-452 could suppress C2C12 myoblast proliferation but accelerate myogenic differentiation. Bioinformatics analysis and dual luciferase report assays showed that Angiopoietin 1 (ANGPT1), RB1, and CACNB4 were the potential target genes of miR-452. To further confirm the target relationship between ANGPT1, RB1, and CACNB4 with miR-452, the mRNA level and protein level of these genes were detected by using RT-qPCR and Western blot, respectively. Result analysis indicated that ANGPT1 was a target gene of miR-452. In addition, knockdown of ANGPT1 could obviously promote C2C12 myoblast proliferation but block their differentiation. In summary, these results demonstrated that miR-452 promoted C2C12 myoblast proliferation and inhibited their differentiation via targeting ANGPT1.

Abstract
Progresses in multimodal treatments have significantly improved the outcomes for childhood cancer. Nonetheless, for about one-third of patients with Ewing sarcoma, rhabdomyosarcoma, or osteosarcoma steady remission has remained intangible. Thus, new biomarkers to improve early diagnosis and the development of precision-targeted medicine remain imperative. Over the last decade, remarkable progress has been made in the basic understanding of miRNAs function and in interpreting the contribution of their dysregulation to cancer development and progression. On this basis, this review focuses on what has been learned about the pivotal roles of miRNAs in the regulation of key genes implicated in childhood sarcomas.

Abstract
Objective To screen the gene related to osteosarcoma (OS) metastasis and the molecular mechanism. Methods GEO database and R2 chip analysis platform were used to screen genes related to OS metastasis. UCSC gene browser was used to find the transcription factor (TF) of CLEC5A. The mRNA level and protein expression of CLEC5A in OS tissues and normal tissues were determined by RT‐PCR and Western blotting, respectively. OS cell lines MG‐63 were transfected with CEBPB recombinant plasmid. After transfection, the expression of CLEC5A in MG‐63 cells was determined and the cell proliferation situation was determined by clone formation assay. Results Three genes CLEC5A, ALOX5AP, and RNASE3 were obtained, and CLEC5A has the highest correlation with OS. CLEC5A has screened the gene related to OS metastasis, and CEBPB can be taken as TF regulating downstream gene CLEC5A. CEBPB can regulate the downstream CLEC5A as transcription factor. The relative mRNA level and protein expression of CLEC5A in OS tissues were significantly higher than those in normal tissues. CLEC5A can prevent OS metastasis. Transfection of CEBPB increased the expression of CLEC5A in MG‐63 cells and also inhibited the proliferation of OS. Conclusion CEBPB can inhibit the proliferation of OS cells via regulating the expression of CLEC5A.

Abstract
BACKGROUND Osteosarcoma (OS) is the most commonly occurred primary bone malignancy with high incident rates among children and adolescents. In pharmacologic treatment, the drug ginsenoside has been shown to exert anticancer effects on several malignant diseases. The purpose of this research was to investigate the effect of ginsenoside on the apoptosis and proliferation of human OS MG-63 and Saos-2 cells by regulating the expression of β-catenin. METHODS Human OS MG-63 and Saos-2 cells were assigned into control group, and four groups with treatment by varying concentrations (12.5 μg/mL, 25 μg/mL, 50 μg/mL and 100 μg/mL) of ginsenoside, respectively. Cell growth after treatment was observed through cell slides. The proliferation rate of MG-63 and Saos-2 cells in each group was detected by CCK-8. After cell transfection at 48 h, cell cycle and cell apoptosis were detected by FITC-Annexin V staining and flow cytometry. The protein and mRNA expressions of β-catenin, Cyclin D1, Bcl-2, Bax and cleaved caspase-3 were detected by RT-qPCR and western blot analysis. RESULTS With increased exposure and concentration of ginsenoside, the cell density, total cell numbers and the absorbance of MG-63 and Saos-2 cells gradually decreased. FITC-Annexin V and FITC-Annexin V/PI staining demonstrated that the cell proportion at S phase decreased, whereas the total apoptotic rate of MG-63 and Saos-2 cells was increased. Furthermore, RT-qPCR and western blot analysis highlighted a gradual decrease in protein and mRNA expressions of β-catenin, Bcl-2 and Cyclin D1, while an elevation in those of Bax and cleaved caspase-3. CONCLUSION The results of this study demonstrate that ginsenoside inhibits proliferation and promotes apoptosis of human OS MG-63 and Saos-2 cells by reducing the expressions of β-catenin, Bcl-2 and Cyclin D1 and increasing the expression of Bax and cleaved caspase-3.

Abstract
Osteosarcoma (OS) is the most common bone cancer worldwide. There is evidence that microRNA-409 (miR-409-3p) is involved in tumorigenesis and cancer progression, however, its possible role in OS requires clarification. In the present study, we evaluated the expression level, clinical significance, and mode of action of miR-409-3p in OS. The miR-409-3p levels were diminished in the OS cells and tissues compared with associated adjacent non-tumor tissues and a non-cancer osteoplastic cell line. Low miR-409-3p expression levels were associated with clinical stage and distant metastasis in patients with OS. Resumption of miR-409-3p expression attenuated OS cell proliferation and invasion. Additionally, based on informatics analyses, we predicted that zinc-finger E-box-binding homeobox-1 (ZEB1) is a possible target of miR-409-3p. This hypothesis was confirmed using luciferase reporter assays, reverse transcription-quantitative real-time polymerase chain reaction, and Western blot analyses. The findings of the current study indicated that ZEB1 was up-regulated in the OS tissues and cell lines, and that this up-regulation was inversely proportional to miR-409-3p expression levels. Furthermore, down-regulation of ZEB1 decreased OS cell invasion and proliferation, illustrating that the tumor suppressive role of miR-409-3p in OS cells may be exerted via negative regulation of ZEB1. Taken together, our observations highlight the potential role of miR-409-3p as a tumor suppressor in OS partially through down-regulation of ZEB1 and suggest that miR-409-3p has potential applications in OS treatment.

Abstract
PURPOSE Although microRNAs (miRNAs) were revealed as crucial modulators in tumor metastasis and target therapy, our understanding of their roles in metastatic renal cell carcinoma (mRCC) and Sunitinib treatment was limited. Here we sought to identify human miRNAs that acted as key regulators in renal cancer metastasis and Sunitinib treatment. EXPERIMENTAL DESIGN We focused on 2 published microarray data to select out our anchored miRNA and then explored the roles of miR-452-5p both in vitro and in vivo, which was downregulated after Sunitinib treatment while upregulated in metastasis renal cell carcinoma (RCC) tissues. RESULTS Here, we discovered that treating with Sunitinib, the targeted receptor tyrosine kinase inhibitor (TKI), inhibited renal cancer cell migration and invasion via attenuating the expression of miR-452-5p. The novel identified miR-452-5p was upregulated and associated with poor prognosis in RCC. Preclinical studies using multiple RCC cells and xenografts model illustrated that miR-452-5p could promote RCC cell migration and invasion in vitro and in vivo. Mechanistically, P65 could directly bind to the miR-452-5p promoter and thus transcriptionally induce miR-452-5p expression, which led to post-transcriptionally abrogate SMAD4 expression, thus inhibition of its downstream gene SMAD7. CONCLUSION Our study presented a road map for targeting this newly identified miR-452-5p and its SMAD4/SMAD7 signals pathway, which imparted a new potential therapeutic strategy for mRCC treatment.

Abstract
INTRODUCTION MicroRNAs (miRNAs) are a group of small non-coding RNAs that affect multiple aspects of tumor biology including chemo resistance. miR-181b has been reported to modulate multidrug resistance in non-small cell lung cancer cells. This study was undertaken to determine the role of miR-181b in chemo resistance of small cell lung cancer cells. MATERIAL AND METHODS This study was undertaken to determine the role of miR-181b in chemoresistance of small cell lung cancer cells with use of qRt-PCR, WB, bioinformatics analysis, and double luciferase reporter system. RESULTS Our data showed that miR-181b was significantly downregulated in cisplatin-resistant H446 small cell lung cancer cells, compared to parental cells, compared to parental cells. Ectopic expression of miR-181b inhibited cell proliferation and invasion in cisplatin-resistant H446 cells (p = 0.023). Moreover, overexpression of miR-181b increased the susceptibility of cisplatin-resistant H446 cells to cisplatin. Mechanistic investigations demonstrated that miR-181b inhibited B-cell lymphoma-2 (Bcl-2) expression by binding to the 3'-untranslated region. Overexpression of Bcl-2 reversed miR-181b-mediated chemo sensitization, which is accompanied by a reduced apoptotic response. CONCLUSIONS Taken together, this work demonstrated that miR-181b might have the ability to overcome chemo resistance of small cell lung cancer cells, and restoration of this miRNA may represent a potential therapeutic strategy for improving chemo sensitivity in small cell lung cancer.

Abstract
T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological cancer. Although microRNA (miR)-452 serves as a tumor suppressor in multiple solid tumors, its expression and function in hematological cancers including T-ALL is largely unknown. We measured the expression of miR-452 in 38 T-ALL and 22 normal lymph node samples by real-time PCR analysis. The methylation levels in the promoter of miR-452 were determined using MethyLight assay. The effects of miR-452 overexpression on proliferation, cell cycle distribution, and tumorigenesis were explored. It was found that miR-452 expression levels were significantly lower in T-ALL specimens than in normal lymph node biopsies (P=0.0079). T-ALL specimens had a significantly higher methylation level in the promoter of miR-452 than normal lymph node tissues (P=0.0014). Consistently, miR-452 was downregulated in Jurkat and Molt-4 T-ALL cells, whose expression was restored after treatment with a demethylation agent 5-aza-2′-deoxycytidine. Ectopic expression of miR-452 inhibited the proliferation of Jurkat and Molt-4 cells and induced a G0/G1 cell cycle arrest. Overexpression of miR-452 suppressed the protein expression of BMI1 in T-ALL cells. Rescue experiments revealed that overexpression of BMI1 partially reversed the growth-suppressive effect of miR-452 on T-ALL cells. Xenograft tumor studies confirmed that overexpression of miR-452 suppressed tumor growth in nude mice and reduced the expression of BMI1. Collectively, miR-452 is epigenetically silenced and targets BMI1 to exert a growth suppressive activity in T-ALL. Restoration of miR-452 expression may represent a promising therapeutic strategy for this malignancy.

Abstract
Introduction This study aimed to elucidate the prognostic value of microRNAs (miRNAs) in patients with osteosarcoma. Materials and Methods Studies were recruited by searching PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, and Wanfang data-bases (final search update conducted January 2017). Eligible studies were identified and the quality was assessed using multiple search strategies. Results A total of 55 articles that investigated the correlation between miRNA expression and either patient survival or disease recurrence in osteosarcoma was initially identified. Among these, 30 studies were included in the meta-analysis. The results of our meta-analysis revealed that elevated levels of miR-21, miR-214, miR-29, miR-9 and miR-148a were associated with poor prognosis in osteosarcoma. Additionally, downregulated miR-382, miR26a, miR-126, miR-195 and miR-124 expression indicated poor prognosis in osteosarcoma. Conclusions miRNAs may act as independent prognostic factors in patients with osteosarcoma and are useful in stratifying risk.
