Abstract
Accumulating evidence shows that the disruption of competing endogenous RNA (ceRNA) networks plays a significant role in osteosarcoma (OS) initiation and progression. However, the specific roles and functions of the ceRNAs in OS remain unclear. First, differentially expressed microRNAs (DEMs) were identified by mining the E-MTAB-1136 and GSE28423 datasets. MiRWalk website was used to predict the target gene of miRNA. OS-associated circular RNA (circRNA) expression profiles were downloaded from the published microarray databases. Gene expression levels were assessed through reverse transcription-quantitative PCR and western blotting. The biological effects of circKEAP1, microRNA (miR)-486-3p and membrane-associated RINGCH finger protein 1 (MARCH1) in OS cells were investigated using Cell Counting Kit-8, Transwell, colony formation and wound healing assays. miR-486-3p was aberrantly downregulated in OS tissues and cell lines and was packed with exosomes. miR-486-3p overexpression was shown to inhibit OS cell progression and promoted cell cycle arrest in vitro. In addition, MARCH1 was identified as a direct downstream molecule of miR-486-3p in OS cells. circKEAP1 was found to be upregulated in OS tissues and cells. circKEAP1 was found to have binding sites with miR-486-3p. Mechanistically, circKEAP1 positively regulated MARCH1 expression by sponging miR-486-3p. Exosomal miR-486-3p inhibited the progression of OS by sponging the circKEAP1/MARCH1 axis. These findings may provide a promising treatment approach for OS.

Abstract
Circular RNA (circRNA) is endogenous noncoding RNA found throughout the eukaryotic genome. It regulates several biological activities at the transcription or post-transcription level. However, the underlying function of circRNA in bovine skeletal muscle development remains unknown. Here, we identified a novel circRNA, circNDST1, and investigated its function and mechanism on the proliferation and differentiation of bovine myoblasts. At the molecular and cellular levels, circNDST1 could promote bovine myoblasts proliferation and inhibit differentiation. Mechanistically, circNDST1 is expressed in the cytoplasmic of myoblast and was enriched by protein Ago2. circNDST1 acts as a competing endogenous RNA that sponges miR-411a and alleviates the inhibitory effect on its target gene, Smad4. miR-411a and Smad4 were also involved in regulating bovine myoblast proliferation and differentiation. These findings suggest that circNDST1 functions as a competing endogenous RNA and regulates bovine myoblast proliferation and differentiation through the miR-411a/Smad4 axis.

Abstract
Induction of endogenous regenerative capacity has emerged as one promising approach to repair damaged hearts following myocardial infarction (MI). Re-expression of factors that are exclusively expressed during embryonic development may reactivate the ability of adult cardiomyocytes to regenerate. Here, we identified miR-411 as a potent inducer of cardiomyocyte proliferation. Overexpression of miR-411 in the heart significantly increased cardiomyocyte proliferation and survival in a model MI. We found that miR-411 enhances the activity of YAP, the main downstream effector of the Hippo pathway, in cardiomyocytes. In conclusion, miR-411 induces cardiomyocyte regeneration and improves cardiac function post-MI likely by modulating the Hippo/YAP pathway.

Abstract
Among kids and juveniles, osteosarcoma (OS) is a common bone malignancy. Circular RNAs (circs, circRNAs) play important roles in multiple malignancies including OS, yet circ_0078767ʹs biological functions in OS are far from well elucidated. This study is targeted at understanding circ_0078767ʹs biological functions in OS and its molecular mechanisms. This study confirmed that circ_0078767 expression was reduced in OS cell lines and tissues. Circ_0078767 overexpression remarkably inhibited OS cell growth, migration, invasion, epithelial-mesenchymal transition (EMT), and promoted apoptosis, whereas circ_0078767 knockdown resulted in the opposite effects. MicroRNA-889 (miR-889) was targeted and regulated by circ_0078767, and miR-889 could negatively modulate Kruppel-like factor 9 (KLF9) expression. Besides, circ_0078767 positively regulated KLF9 expression in OS cells via repressing miR-889. In conclusion, circ_0078767 enhances KLF9 expression by targeting miR-889 to inhibit OS progression.

Abstract
MiRNA accounts for 1-3% of genes but regulates more than 30% of gene expression in humans. This article analyzes the current deficiencies and challenges of miR-411 research and looks forward to the prospects of miR-411 in cancer. MiR-411 is a non-coding RNA located on chromosome 14. MiR-411 is abnormally expressed in a variety of cancers. The dysregulation of miR-411 can affect cancer cell proliferation, invasion, migration, apoptosis, colony formation, etc. miR-411 can be regulated by different lncRNAs and circRNAs. By targeting multiple genes, miR-411 participates in the activation of the MAPK signaling pathway, PI3K/AKT/mTOR signaling pathway, p53 signaling pathway, Ras signaling pathway, NF-κB signaling pathway, and Wnt/β-catenin signaling pathway. The expression of miR-411 is related to the diagnosis, prognosis, and sensitivity of drugs in cancer patients. In conclusion, this work outlines the molecular mechanisms and cellular functions of aberrant expression of miR-411 and its target genes in cancer to reveal its potential value in diagnosis, prognosis, and drug sensitivity.

Abstract
Osteosarcoma is a prevalent malignant bone cancer. This study aimed to explore the biologic role and potential mechanism of circ_0003732 in osteosarcoma carcinogenesis. Quantitative real-time PCR was implemented to detect the RNA expression of circ_0003732, microRNA-377-3p (miR-377-3p) and cytoplasmic polyadenylation element-binding protein 1 (CPEB1). Cell proliferation was evaluated by cell counting kit-8 assay and colony formation assay. Transwell, wound healing and flow cytometry assays were employed to assess cell migration, invasion and apoptosis. In addition, the interaction between miR-377-3p and circ_0003732 or CPEB1 was validated by dual-luciferase reporter assay. The protein expression was detected by western blot assay or immunohistochemistry assay. Xenograft tumor assay was performed to explore the regulation of circ_0003732 on osteosarcoma tumor growth in vivo. Circ_0003732 was upregulated in osteosarcoma tissues and cells. Knockdown of circ_0003732 suppressed osteosarcoma cell proliferation, migration, invasion and triggered cell apoptosis in vitro, as well as reduced osteosarcoma tumor growth in vivo. Meanwhile, miR-377-3p could bind to circ_0003732 and CPEB1 and miR-377-3p inhibitor could reverse the effects of circ_0003732 silence on osteosarcoma cell progression. Furthermore, CPEB1 overexpression could overturn the suppressive impacts of miR-377-3p on osteosarcoma progression. In addition, circ_0003732 silence restrained Wnt/β-catenin signaling pathway via regulating miR-377-3p in osteosarcoma cells. Circ_0003732 might play a positive role in the malignant progression of osteosarcoma by regulating the miR-377-3p/CPEB1 axis and activating the Wnt/β-catenin signaling pathway, which might provide new insights for osteosarcoma therapy.

Abstract
MicroRNAs (miRNAs) are a class of small (20-24 nucleotides), highly conserved, non-coding RNA molecules whose main function is the post-transcriptional regulation of gene expression through sequence-specific manners, such as mRNA degradation or translational repression. Since these key regulatory molecules are implicated in several biological processes, their altered expression affects the preservation of cellular homeostasis and leads to the development of a wide range of pathologies. Over the last few years, relevant investigations have elucidated that miRNAs participate in different stages of bone growth and development. Moreover, the abnormal expression of these RNA molecules in bone cells and tissues has been significantly associated with the progression of numerous bone diseases, including osteoporosis, osteosarcoma, osteonecrosis and bone metastasis, among others. In fact, miRNAs regulate multiple pathological mechanisms, including altering either osteogenic or osteoblast differentiation, metastasis, osteosarcoma cell proliferation, and bone loss. Therefore, in this present review, aiming to impulse the research arena of the biological implications of miRNA transcriptome in bone diseases and to explore their potentiality as a theragnostic target, we summarize the recent findings associated with the clinical significance of miRNAs in these ailments.

Abstract
Osteosarcoma (OS) is a fast-progressing bone tumor with high incidence in children and adolescents. The main diagnostic methods for OS are imaging exams and biopsies. In spite of the several resources available for detecting the disease, establishing an early diagnosis is still difficult, resulting in worse prognosis and lower survival rates for patients with OS. The identification of novel biomarkers would be helpful, and recently, circulating microRNAs (miRNAs) have been pointed to as possible non-invasive biomarkers. In order to assess the effectiveness of miRNA research, we performed a systematic review to assess the potential role of circulating miRNAs as biomarkers for OS diagnosis. We performed a search in various databases—PubMed, LILACS (Literatura Latino-americana e do Caribe em Ciências da Saúde), VHL (Virtual Health Library), Elsevier, Web of Science, Gale Academic One File—using the terms: “Circulating microRNAs” OR “plasma microRNAs” OR “serum microRNAs” OR “blood microRNAs” OR “cell-free microRNAs” OR “exosome microRNAs” OR “extracellular vesicles microRNAs” OR “liquid biopsy” AND “osteosarcoma” AND “diagnostic”. We found 35 eligible studies that were independently identified and had had their quality assessed according to Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) guidelines. Despite the useful number of publications on this subject and the fact that several microRNAs showed excellent diagnostic performance for OS, the lack of consistency in results suggests that additional prospective studies are needed to confirm the role of circulating miRNAs as non-invasive biomarkers in OS.

Abstract
Background Numerous studies have demonstrated that noncoding RNAs are involved in choriocarcinoma (CC). The competing endogenous RNA (ceRNA) network plays an important role in the occurrence and development of carcinoma. However, the involvement of the ceRNA network in CC remains unclear. The current study aimed to investigate the regulatory mechanism of ceRNA in CC. Material/Methods We downloaded the messenger RNAs (mRNAs) expression profiles (GSE20510 and GSE65654) and microRNAs (miRNAs) expression profiles (GSE32346 and GSE130489) from GEO datasets. The limma package of R software was used to identify differentially expressed RNAs (DERNAs). Then, we performed functional annotation of the differentially expressed mRNAs (DEmRNAs). TargetScan, miRDB, miRWalk, and Starbase were used to construct a CC-specific ceRNA network and select key molecules. Results The results identified a total of 177 DEmRNAs and 189 differentially expressed miRNAs (DEmiRNAs) between the trophoblast and CC cell line samples. Ten differentially expressed lncRNAs (DElncRNAs) were obtained based on experimental studies. The DEmRNAs were mainly enriched in cell proliferation, positive regulation of the apoptotic process, and cell death. A total of 10 genes were ascertained as hub genes. Based on DEmRNAs, DEmiRNAs, and DElncRNAs, a CC-specific ceRNA network was established. Five DElncRNAs, 15 DEmiRNAs, and 45 DEmRNAs were identified. In addition, LINC00261, MEG3, MALAT1, H19, and OGFRP1 were identified as 5 key lncRNAs in choriocarcinoma. Conclusions This study provides novel insights into CC mechanisms and identified potential therapeutic targets for CC.

Abstract
Metastasis is the primary cause of the high mortality rates in head and neck squamous cell carcinoma (HNSCC). MicroRNA (miR)‑411‑5p has been discovered to serve an important role in cancer metastases. However, to the best of our knowledge, the association between miR‑411‑5p expression levels and HNSCC metastasis has not been thoroughly investigated. The present study aimed to research the function of miR‑411‑5p in HNSCC metastasis. The results of the present study revealed that miR‑411‑5p expression levels were upregulated in patients with HNSCC with lymph node metastasis and the upregulated expression levels of miR‑411‑5p were positively associated with the metastatic potential of HNSCC. Moreover, miR‑411‑5p promoted HNSCC cell migration, invasion and epithelial‑mesenchymal transition (EMT). The results of the dual‑luciferase reporter assays identified RING1 and YY1 binding protein (RYBP) as a functional downstream target gene for miR‑411‑5p. Therefore, whether miR‑411‑5p downregulated the expression levels of RYBP in HNSCC cells was subsequently investigated. Notably, the silencing of RYBP expression restored the stimulatory effects of miR‑411‑5p on HNSCC cell migration, invasion and EMT. In addition, the mRNA expression levels of miR‑411‑5p and RYBP were found to be inversely correlated in HNSCC samples. In conclusion, the results of the present study indicated that the miR‑411‑5p‑mediated downregulation of RYBP expression levels may exert an important role in HNSCC metastasis and may provide a novel target for the treatment of HNSCC.

Abstract
Osteosarcoma (OS) is the most common primary malignant tumor of the skeletal system in the clinic. It mainly occurs in adolescent patients and the pathogenesis of the disease is very complicated. The distant metastasis may occur in the early stage, and the prognosis is poor. MicroRNAs (miRNAs) are non-coding RNAs of about 18–25 nt in length that are involved in post-transcriptional regulation of genes. miRNAs can regulate target gene expression by promoting the degradation of target mRNAs or inhibiting the translation process, thereby the proliferation of OS cells can be inhibited and the apoptosis can be promoted; in this way, miRNAs can affect the metabolism of OS cells and can also participate in the occurrence, invasion, metastasis, and recurrence of OS. Some miRNAs have already been found to be closely related to the prognosis of patients with OS. Unlike other reviews, this review summarizes the miRNA molecules closely related to the development, diagnosis, prognosis, and treatment of OS in recent years. The expression and influence of miRNA molecule on OS were discussed in detail, and the related research progress was summarized to provide a new research direction for early diagnosis and treatment of OS.

Abstract
OBJECTIVE This study aimed to identify potential key microRNAs (miRNAs) in osteosarcoma and construct miRNA-mRNA negative regulatory networks through analysis of the Gene Expression Omnibus (GEO) database. METHODS The differentially expressed miRNAs (DE-miRNAs) in GSE28423 were screened, and their prognostic value was assessed with the prognostic data of GSE39058. The target genes of prognostic DE-miRNAs were predicted and underwent Gene Ontology (GO) classification and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. In addition, the expression of all predicted target genes were assessed using the mRNA array data of GSE28424. Finally, the gene-drug interaction network was constructed. RESULTS We identified 205 DE-miRNAs between osteosarcoma cells and normal bone. Among them, high expression of miR-411-3p and miR-487b-5p were correlated with prolonged survival. Furthermore, 2659 genes predicted as targets of miR-411-3p or miR-487b-5p were clustered in 42 significant GO categories, including "regulation of neurotransmitter secretion" and "phosphoprotein binding", as well as 23 significant KEGG pathways, such as "MAPK signaling pathway" and "Ras signaling pathway". Five of the 75 overlapping target genes of miR-411-3p and miR-487b-5p were downregulated in osteosarcoma, including ZBTB20, ADAMTS4, GLIPR2, CLIC5 and CBX7. CONCLUSIONS Our findings might help clarify molecular mechanisms underlying the oncogenesis and development, and offer potential targets for osteosarcoma.

Abstract
The mortality rate of ovarian cancer is the highest out of all gynecological malignancies worldwide. Therefore, it is important to understand the mechanisms of ovarian cancer, identify new biomarkers and develop targeted drugs. The role and molecular mechanisms of hsa-microRNA (miR)-411-5p in ovarian cancer have not been fully elucidated. The present study investigated the ovarian cancer cell lines OVCAR-8 and SKOV3. After transfection with miRNA mimics, cell proliferation was monitored by a proliferation assay. Furthermore, cell migration was measured by a cell wound healing assay and cell invasion was measured by Matrigel invasion assays. A miRNA luciferase reporter assay was used to analyze the relationship between miRNAs and the target gene HMMR, which was then further evaluated by gene differential analysis. In the current study, hsa-mir-411-5p was identified as a miRNA regulator of the hyaluronan mediated motility receptor, which negatively regulated the activity of ERK1/2 and ultimately inhibited ovarian cancer cell proliferation and motility. Although hsa-mir-411-5p may have different roles in other types of cancer, the present study suggested that miR-411-5p functions as a negative tumor regulator in ovarian cancer cells, displaying the potential of miR-411-5p as a biomarker for ovarian cancer.

Abstract
Rheumatoid arthritis (RA) is a chronic and inflammatory synovitis systemic disease. Due to the unknown pathogenesis, this study was to investigate the effect of microRNA (miR)-411 on apoptosis and joint function of synoviocytes in RA mice via RIPK1-mediated NF-κB signaling pathway. The collagen-induced arthritis model mice were induced via collagen type II and Freund's adjuvant. The mice were injected with miR-411 mimics, si-RIPK1 or miR-411 mimics + oe-RIPK1 to figure out their roles in cell apoptosis and inflammation of synovial tissues. Synoviocytes were grouped as in animal experiments. Proliferation and apoptosis of synoviocytes were detected upon treatment with overexpressed miR-411 and silenced RIPK1. The expression of miR-411, RIPK1 and NF-κB in synovial tissues and synoviocytes of RA mice was detected by RT-qPCR and Western blot analysis. Poorly expressed miR-411, and highly expressed NF-κB and RIPK1 existed in synovial tissue and synoviocytes of RA. Additionally, it was found that si-RIPK1 decreased NF-κB expression, and miR-411 mimics decreased both RIPK1 and NF-κB. MiR-411 had a targeted relationship with RIPK1. si-RIPK1 or miR-411 mimics promoted cell apoptosis and strained inflammation in synovial tissues of mice with RA. Overexpressed miR-411 or silencing RIPK1 inhibited the proliferation and promoted apoptosis of synoviocytes of RA mice. Up-regulation of miR-411 or down-regulation of RIPK1 had a certain inhibitory effect on RA. This study suggests that up-regulated miR-411 or down-regulated RIPK1 promoted apoptosis and inhibited proliferation of synoviocytes of RA mice, which may be related to the inhibition of NF-κB activation.

Abstract
Background Osteoarthritis (OA) is the most common joint disease and is characterized by the progressive degeneration of articular cartilage. The molecular basis of OA involves various factors and has not been fully clarified. Autophagy is a conserved catabolic process that involves cellular degradation through the lysosomal machinery. Material/Methods We found that miRNA-411 regulates chondrocyte autophagy in OA by targeting hypoxia-inducible factor 1 alpha (HIF-1α) and identified the related molecular mechanism. OA condition in chondrocyte C28/I2 cells was induced by treatment with interleukin 1 beta (IL-1β). The protein expressions of LC3, p62, HIF-1α, ULK-1, and Beclin-1 were assessed by Western blot analysis, and LC3 expression was assessed by immunofluorescence. Results TargetScan analysis showed that HIF-1α mRNA is directly targeted by miR-411, which was confirmed by luciferase reporter assay. miR-411 mimic decreased HIF-1α levels in chondrocytes while miR-411 inhibitor increased HIF-1α levels in chondrocytes. Furthermore, expression of LC3, ULK-1, P62, and Beclin-1 in chondrocytes was induced by miR-411 inhibitor and was downregulated by miR-411 mimics. In addition, miR-411 mimics reduced the expression level of LC3, as determined by immunofluorescence analysis. Conclusions Our results demonstrate that miR-411 promotes chondrocyte autophagy by targeting HIF-1α, suggesting that regulating HIF-1α by miR-411 might be a therapeutic strategy for OA.

Abstract
Glioma is an aggressive brain cancer with poor prognosis and high invasiveness. Dysregulation of circular RNAs (circRNAs) has been widely discovered in various cancers, including glioma. However, the molecular mechanism of circ_0034642 in glioma is still unclear. The expression of circ_0034642, microRNA (miR)-625-5p and transgelin-2 (TAGLN2) in glioma tumors and cells was detected by performing a quantitative real-time polymerase chain reaction (qRT-PCR). The stability of circ_0034642 was determined by carrying out RNase R treatment. Cell proliferation was evaluated by performing the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. Glycolysis was analyzed by measuring the extracellular acidification rate (ECAR) using glucose detection and lactic acid detection kits. Cell migration and invasion were determined by performing the transwell assay. Protein expression levels of the proteins hexokinase 2 (HK2), matrix metalloproteinase-2 (MMP2), matrix metalloproteinase-9 (MMP9) and TAGLN2 were analyzed using western blots. The interaction between miR-625-5p and circ_0034642 or TAGLN2 was proved using a dual-luciferase reporter system. Animal models were established by subcutaneously injecting glioma cells stably transfected with sh-NC or sh-circ_0034642. Circ_0034642 and TAGLN2 were overexpressed whereas miR-625-5p was expressed at low levels in glioma tumors and cells. Moreover, circ_0034642 and TAGLN2 were upregulated while miR-625-5p was downregulated under hypoxic conditions in a time-dependent manner. Next, elimination of circ_0034642 was shown to inhibit cell glycolysis, proliferation, migration and invasion under hypoxic conditions in gliomas. Then, we found that circ_0034642 acted as a “sponge” of miR-625-5p while TAGLN2 acted as a target of miR-625-5p. In addition, recovery of circ_0034642 attenuated the repression mediated by miR-625-5p on glioma cell glycolysis and progression under hypoxic conditions. Meanwhile, an inhibitor of miR-625-5p alleviated TAGLN2 deficiency-induced inhibition of glioma cell development under hypoxic conditions. We also discovered that circ_0034642 could interact with miR-625-5p and further alter the expression of TAGLN2. Lastly, a circ_0034642 knockdown hindered tumor growth in vivo by regulating the miR-625-5p/TAGLN2 axis. Enhanced expression of circ_0034642 was found to promote cell glycolysis, proliferation, migration and invasion under hypoxic conditions in gliomas by sponging miR-625-5p to improve TAGLN2 expression, providing prospective biomarkers for the diagnosis of glioma. Circ_0034642 was upregulated under hypoxic conditions in gliomas.![]()

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
Cervical cancer is one of the most common gynecological malignancies worldwide. However, the pathogenesis of cervical cancer remains to be fully elucidated. Increasing evidence shows that microRNAs (miRNAs) may be involved in the pathogenesis of cervical cancer. The present study tested the hypothesis that the overexpression of miRNA (miR)-411 may delay, whereas the overexpression of serine/threonine kinase 17a (STK17A) may contribute to, cervical cancer development and progression through the p53 pathway. Cervical cancer tissues and adjacent normal tissues were obtained from 141 patients with cervical cancer following radiotherapy, with efficacy evaluated. The receiver operating characteristic curve was plotted to show the value of miR-411 and STK17A in predicting the efficacy of radiotherapy. Cox's proportional hazards regression model was utilized for multivariate analysis. A series of inhibitors, mimics or small interfering RNAs against STK17A were introduced to validate the regulatory mechanism of miR-411 in governing STK17A, determined with a luciferase reporter gene assay. The expression of miR-411 and STK17A, and the status of the p53 signaling pathway were evaluated. The colony forming ability, proliferation, migration, invasion and apoptosis of CaSki cells were assessed using a colony formation assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, Transwell assay and flow cytometry, respectively. miR-411 was upregulated but STK17A was reciprocal in cervical tissues. The overexpression of miR-411 and low expression of STK17A were correlated with high efficacy of radiotherapy. miR-411 and STK17A had predictive value for the efficacy of radiotherapy; miR-411 was the protective factor and STK17A was a risk factor for prognosis of cervical cancer. Increasing miR-411 activated the p53 signaling pathway and promoted cell apoptosis, but inhibited cell proliferation, invasion and migration. STK17A, an miR-411 target, increased following miR-411 over-expression, whereas the p53 signaling pathway was activated following STK17A inhibition. It was observed that the effect of miR-411 inhibition was lost following STK17A silencing. These findings indicate that the miR-411-mediated direct suppression of STK17A induces apoptosis and suppresses the proliferation, migration and invasion of human cervical cancer cells via the p53 signaling pathway. Additionally, miR-411 and STK17A have predictive value for the efficacy of radiotherapy.

Abstract
Background The long noncoding RNA, small nucleolar RNA host gene 8 (SNHG8), is upregulated in multiple human cancer types. However, whether SNHG8 is aberrantly expressed in esophageal squamous cell carcinoma (ESCC) and its biological functions have yet to be elucidated. Thus, we aimed to determine the expression status of SNHG8 in ESCC, explore the effects of SNHG8 on the oncogenicity of ESCC, and investigate the potential underlying mechanisms. Methods SNHG8 expression in ESCC tissues and cell lines was determined via reverse-transcription quantitative polymerase chain reaction. The actions of SNHG8 on the malignant characteristics of ESCC were explored using CCK-8 assay, flow-cytometric analysis, Transwell migration and invasion assays, and tumor xenografts in nude mice. Results SNHG8 expression was significantly higher in ESCC tissues and cell lines. High SNHG8 expression was revealed to closely correlate with primary tumor invasion depth, lymph node metastases, TNM stage, and worse overall survival among patients with ESCC. Functional investigation showed that ablation of SNHG8 notably restricted ESCC cell proliferation, migration, and invasion while inducing apoptosis in vitro and hindered tumor growth in vivo. In the meantime, SNHG8 acted as a molecular sponge of microRNA-411 (miR-411) in ESCC. Furthermore, miR-411 exerted a tumor-suppressive effect on ESCC cells, and karyopherin alpha 2 (KPNA2) turned out to be a direct target gene of miR-411. Restoring KPNA2 expression neutralized the inhibitory effects of miR-411 overexpression on the malignant behaviors of ESCC cells. Moreover, silencing of miR-411 abrogated the influence of SNHG8 downregulation in ESCC cells. Conclusion SNHG8 may play oncogenic roles in the malignancy of ESCC by sponging miR-411 to increase KPNA2 expression. The SNHG8–miR-411–KPNA2 pathway may be a novel target for the treatment of patients with ESCC and offer potential biomarkers for the diagnosis and prognosis of ESCC.

Abstract
The high mortality of colorectal cancer (CRC) is likely caused by early invasion and metastasis. The chemoresistance of tumor cells is the critical reason for treatment failure. The present study aimed to develop targeted solutions to overcome chemotherapy drug resistance in CRC. CCK-8 assay was used to examine SW480 cell viability. SW480 cell apoptosis was examined using flow cytometry. The present study demonstrated that the expression of miR-1271 was significantly decreased in CRC tumors and cell lines compared with control tissues. Furthermore, the expression of microRNA (miR)-1271 was increased and decreased following the transfection of miR-1271 mimics and an inhibitor, respectively. Furthermore, miR-1271 regulated mammalian target of rapamycin (mTOR) expression by directly binding to the mTOR 3'-untranslated region and the relative luciferase activity of mTOR was decreased following miR-1271 overexpression. The results of the present study indicate that miR-1271 may be a potential target for anti-CRC therapy, particularly in the sensitivity of chemotherapeutic drugs. miR-1271 may therefore enhance the sensitivity of CRC cells to chemotherapy drugs and provide a novel approach for the gene therapy of CRC.

miR-425-5p decreases LncRNA MALAT1 and TUG1 expressions and suppresses tumorigenesis in osteosarcoma via Wnt/β-catenin signaling pathway. Int J Biochem Cell Biol 2019; 111:42-51. [PMID: 30986552 DOI: 10.1016/j.biocel.2019.04.004] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Revised: 03/25/2019] [Accepted: 04/09/2019] [Indexed: 12/14/2022]
Abstract
Multiple miRNAs have been recognized as critical regulators in osteosarcoma (OS) carcinogenesis. miR-425-5p was demonstrated to be downregulated in the serum of OS patients. However, the detailed roles of miR-425-5p in OS progression and its underlying molecular mechanism are far from being addressed. In our study, the reduced expression of miR-425-5p was observed in OS tissues and cells. Functional analyses showed that miR-425-5p overexpression suppressed OS cell proliferation, invasion and migration in vitro. Moreover, miR-425-5p upregulation decreased the expressions of MALAT1 and TUG1 in OS cells via directly binding them. miR-425-5p upregulation strikingly abrogated the activation of Wnt/β-catenin signaling pathway induced by MALAT1 and TUG1 overexpression in OS cells. Finally, we validated that miR-425-5p hindered OS tumor growth, and suppressed MALAT1 and TUG1 expressions and the Wnt/β-catenin signaling pathway in vivo. Our findings concluded that miR-425-5p suppressed the tumorigenesis of OS via decreasing MALAT1 and TUG1 expressions through inactivation of the Wnt/β-catenin signaling pathway, contributing to a better understanding of the molecular mechanism of the tumorigenesis of OS.
