Abstract
Purpose The main purpose of this paper is to explore the interaction between GAS5 and miR-135b-5p to understand their function in the metastasis, invasion, and proliferation of glioma. This may provide new ideas for the pathogenesis and treatment of glioma. Patients and Methods Western blotting assays and RT‑qPCR were employed to investigate the expression of related genes in glioma tissues or cell lines. CCK-8 was used to examine the impact of GAS5 on cell viability. Motile activities were adopted by the transwell and wound healing experiments. A double luciferase experiment was performed to elucidate transcriptional regulation. Results GAS5 showed low expression in glioma cells and tissues, and up-regulation of GAS5 could depress the invasion, proliferation, and metastasis of glioma. GAS5 negatively regulates miR-135b-5p, which can counteract the cellular effects caused by GAS5. APC was the target of miR-135b-5p, and GAS5 can regulate the expression of APC by sponging miR-135b-5p. APC overexpression reversed the effects of miR-135b-5p promotion on glioma cells, while miR-135b-5p has the opposite function. As a downstream target gene of GAS5, miR-135b-5p was negatively regulated by GAS5. The restoration of miR-135b-5p can remarkably reverse the impact of GAS5 on glioma cells. In addition, GAS5 increased the expression of APC in glioma cells by inhibiting miR-135b-5p. Conclusion GAS5 increased APC expression by restraining miR-135b-5p and partially blocked the progression of glioma, suggesting that it could be an advantageous therapeutic target for glioma intervention.

Abstract
Long non-coding RNAs (lncRNAs), which comprise most non-coding RNAs (ncRNAs), have recently become a focus of cancer research. How many functional ncRNAs exist is still a matter of debate. Although insufficient evidence supports that most lncRNAs function as transcriptional by-products, it is widely known that an increasing number of lncRNAs play essential roles in cells. Small nucleolar RNAs (snoRNAs), 60-300 nucleotides in length, have been better studied than long non-coding RNAs (lncRNAs) and are predominantly present in the nucleolus. Most snoRNAs are encoded in introns of protein- and non-protein-coding genes called small nucleolar RNA host genes (SNHGs). In this article, we explore the biology and characteristics of SNHGs and their role in developing human malignancies. In addition, we provide an update on the ability of these snoRNAs to serve as prognostic and diagnostic variables in various forms of cancer.

Abstract
BACKGROUND Protein L-isoaspartate (D-aspartate) O-methyltransferase (PCMT1) is a highly conserved protein repair enzyme that participates in regulating the progression of human cancers. We therefore studied the function and the related mechanisms of PCMT1 in breast cancer cells. METHODS Expression profile and prognostic analysis of PCMT1 in breast cancer patients were analyzed using online databases. PCMT1 expression in breast cancer cells was detected by western blot analysis. Cell proliferation was determined by CCK-8 and colony formation assays. Apoptosis was evaluated using flow cytometry analysis and caspase-3/7 activity assay. Cell invasion was assessed by Transwell invasion assay. The small nucleolar RNA host gene 16 (SNHG16)/miR-195/PCMT1 regulatory axis was identified using bioinformatics analysis. RESULTS PCMT1 expression was increased in breast cancer tissues and cells. High PCMT1 expression was correlated with poor prognosis in breast cancer patients. PCMT1 knockdown suppressed cell proliferation and colony formation ability in breast cancer cells. Moreover, PCMT1 knockdown induced apoptosis and restrained the invasive ability in breast cancer cells. PCMT1 overexpression increased the proliferative and invasive abilities of breast cancer cells. miR-195 was identified as the unique upstream miRNA of PCMT1. SNHG16 was identified as the unique upstream lncRNA of miR-195. SNHG16 knockdown downregulated PCMT1 by increasing miR-195 expression. Breast cancer cell proliferation was regulated by the SNHG16/miR-195/PCMT1 axis. CONCLUSION PCMT1 silencing inhibited cell proliferation and invasion and induced apoptosis in breast cancer cells and the SNHG16/miR-195/PCMT1 regulatory axis might serve as a potential therapeutic target for breast cancer.

Front Genet 2022; 13:947551.

Abstract
Background: Cuproptosis is a new type of cell death that induces protein toxic stress and eventually leads to cell death. Hence, regulating cuproptosis in tumor cells is a new therapeutic approach. However, studies on cuproptosis-related long noncoding RNA (lncRNA) in head and neck squamous cell carcinoma (HNSC) have not been found. This study aimed to explore the cuproptosis-related lncRNAs prognostic marker and their relationship to immune microenvironment in HNSC by using bioinformatics methods. Methods: RNA sequencing, genomic mutations, and clinical data of TCGA_HNSC were downloaded from The Cancer Genome Atlas. HNSC patients were randomly assigned to either a training group or a validation cohort. The least absolute shrinkage and selection operator Cox regression and multivariate Cox regression models were used to determine the prognostic model in the training cohort, and its independent prognostic effect was further confirmed in the validation and entire cohorts. Results: Based on previous literature, we collected 19 genes associated with cuproptosis. Afterward, 783 cuproptosis-related lncRNAs were obtained through coexpression. Cox model revealed and constructed eight cuproptosis-related lncRNAs prognostic marker (AL132800.1, AC090587.1, AC079160.1, AC011462.4, AL157888.1, GRHL3-AS1, SNHG16, and AC021148.2). Patients were divided into high- and low-risk groups based on the median risk score. The Kaplan–Meier survival curve revealed that the overall survival between the high- and low-risk groups was statistically significant. The receiver operating characteristic curve and principal component analysis demonstrated the accurate prognostic ability of the model. Univariate and multivariate Cox regression analysis showed that risk score was an independent prognostic factor. In addition, we used multivariate Cox regression to establish a nomogram of the predictive power of prognostic markers. The tumor mutation burden showed significant differences between the high- and low-risk groups. HNSC patients in the high-risk group responded better to immunotherapy than those in the low-risk group. We also found that risk scores were significantly associated with drug sensitivity in HNSC. Conclusion: In summary, our study identified eight cuprotosis-related lncRNAs signature of HNSC as the prognostic predictor, which may be promising biomarkers for predicting the benefit of HNSC immunotherapy as well as drug sensitivity.

Downregulation of lncRNA SNHG16 inhibits vascular smooth muscle cell proliferation and migration in cerebral atherosclerosis by targeting the miR-30c-5p/SDC2 axis. Heart Vessels 2022; 37:1085-1096. [PMID: 35320391 DOI: 10.1007/s00380-022-02049-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Accepted: 02/25/2022] [Indexed: 01/27/2023]
Abstract
Atherosclerosis (AS) is the basic lesion underlying the occurrence and development of cerebrovascular diseases. Abnormal proliferation of vascular smooth muscle cells (VSMCs) plays a crucial role in AS. We aimed to explore the role of SNHG16 in AS and the molecular mechanism of VSMC involvement in the regulation of AS. The expression levels of SNHG16, miR-30c-5p and SDC2 were detected by qRT-PCR. CCK-8, wound healing and Transwell assays were used to assess ox-LDL-induced VSMC proliferation, migration, and invasion, respectively. Western blot analysis was used to detect SDC2 and MEK/ERK pathway-related protein levels. A dual-luciferase reporter assay confirmed the binding of SNHG16 with miR-30c-5p and miR-30c-5p with SDC2. SNHG16 and SDC2 expression was upregulated in patients with AS and ox-LDL-induced VSMCs, while miR-30c-5p was downregulated. Ox-LDL-induced VSMC proliferation and migration were increased, and the MEK/ERK signalling pathway was activated. MiR-30c-5p was targeted to SNHG16 and SDC2. Downregulating SNHG16 or upregulating miR-30c-5p inhibited ox-LDL-induced VSMC proliferation and migration and inhibited MEK/ERK signalling pathway activation. In contrast, downregulating miR-30c-5p or upregulating SDC2 reversed the effects of downregulating SNHG16 or upregulating miR-30c-5p. Furthermore, downregulating SDC2 inhibited ox-LDL-induced proliferation and migration of VSMCs and inhibited activation of the MEK/ERK signalling pathway, while upregulating lncRNA SNHG16 reversed the effects of downregulating SDC2. Downregulation of SNHG16 inhibited VSMC proliferation and migration in AS by targeting the miR-30c-5p/SDC2 axis. This study provides a possible therapeutic approach to AS.

Abstract
Long non-coding RNAs (LncRNAs) are essential regulators in the occurrence and development of AS. Here we aim to explore the underlying molecular mechanism of LncRNA SNHG16 in regulating ox-LDL-induced VSMC proliferation, migration and invasion. After constructing AS in vivo and in vitro models, the expressions of SNHG16, miR-22-3p, HMBG2, proliferation- and metastasis-related proteins were determined by qRT-PCR and Western blot assays. Detection of serological lipids, H&E and Masson staining analysis were conducted to evaluate the AS injury in mice. The effects of ox-LDL treatment on VSMCs were examined by CCK-8, wound scratch and Transwell Chamber assays. The targeted relationship was measured by luciferase reporter and RIP assays. The results showed that SNHG16 and high-mobility group box 2 (HMGB2) expressions were increased while miRNA-22-3p expression was decreased in AS mice and ox-LDL-stimulated VSMCs. Functionally, sh-SNHG16 restrained ox-LDL-induced VSMC growth and migration. SNHG16 suppressed miRNA-22-3p expression by direct binding. Furthermore, in ox-LDL-treated VSMCs, miRNA-22-3p mimic prevented proliferation, migration, and invasion. Further explorations showed that HMGB2 was a target of miRNA-22-3p, SNHG16 upregulated HMGB2 levels by acting as a competing endogenous RNA (ceRNA) of miRNA-22-3p. More importantly, sh-HMGB2 partially reversed the effects of sh-SNHG16 together with miR-22-2p inhibitor on ox-LDL-induced VSMC proliferation, migration and invasion. Collectively, SNHG16 accelerated atherosclerotic plaque (AP) formation and enhanced ox-LDL-activated VSMCs proliferation and migration by miRNA-22-3p/HMGB2 axis.

Abstract
Mounting evidence indicates that long non-coding RNAs (lncRNAs) have critical roles in colorectal cancer (CRC) progression, providing many potential diagnostic biomarkers, prognostic biomarkers, and treatment targets. Here, we sought to investigate the role and underlying regulatory mechanism of lncRNA small nucleolar RNA host gene 16 (SNHG16) in CRC. The expressions of SNHG16 in CRC were identified by RNA-sequencing and quantitative reverse transcription PCR. The functions of SNHG16 were explored by a series of in vitro and in vivo assays (colony formation assay, flow cytometry assay, and xenograft model). Bioinformatics analysis, RNA fluorescencein situ hybridization and luciferase reporter assay were used to investigate the regulatory mechanism of effects of SNHG16. SNHG16 was found to be significantly elevated in human CRC tissues and cell lines. Functional studies suggested that SNHG16 promoted CRC cell growth both in vitro and in vivo. Mechanistically, we identified that SNHG16 is expressed predominantly in the cytoplasm. SNHG16 could interact with miR-214-3p and up-regulated its target ABCB1. This study indicated that SNHG16 plays an oncogenic role in CRC, suggesting it could be a novel biomarker and therapeutic target in CRC.

Abstract
Being located on 17q25.1, small nucleolar RNA host gene 6 (SNHG16) is a member of SNHG family of long non-coding RNAs (lncRNA) with 4 exons and 13 splice variants. This lncRNA serves as a sponge for a variety of miRNAs, namely miR-520a-3p, miR-4500, miR-146a miR-16–5p, miR-98, let-7a-5p, hsa-miR-93, miR-17-5p, miR-186, miR-302a-3p, miR-605-3p, miR-140-5p, miR-195, let-7b-5p, miR-16, miR-340, miR-1301, miR-205, miR-488, miR-1285-3p, miR-146a-5p, and miR-124-3p. This lncRNA can affect activity of TGF-β1/SMAD5, mTOR, NF-κB, Wnt, RAS/RAF/MEK/ERK and PI3K/AKT pathways. Almost all studies have reported oncogenic effect of SNHG16 in diverse cell types. Here, we explain the results of studies about the oncogenic role of SNHG16 according to three distinct sets of evidence, i.e., in vitro, animal, and clinical evidence.

Abstract
The metastasis of osteosarcoma is a major threat to both adolescents and young adults. Identifying novel targets that may prevent osteosarcoma metastasis is critical in developing advanced clinical therapies for treating this cancer. The present study aimed to explore the mechanism of microRNA (miR)-545-5p in the metastasis of osteosarcoma. The present study identified miR-545-5p as a potential target that was downregulated in both osteosarcoma clinical samples and cell lines, and in the latter, ectopically expressed miR-545-5p caused apoptosis. In addition, miR-545-5p exerted inhibitory effects in osteosarcoma migration and invasion. Overexpression of miR-545-5p induced xenograft growth inhibition in vivo. In addition, miR-545-5p targeted dimethyladenosine transferase 1 (DIMT1), an oncogenic protein that facilitates osteosarcoma proliferation, migration and invasion. Taken together, the results of the present study suggest that miR-545-5p functions as a tumor suppressor in osteosarcoma that promotes apoptosis, while inhibiting migration and invasion by targeting DIMT1. Taken together, the results of the present study suggest two potential novel targets for osteosarcoma treatment and metastasis prevention.

Zhou W, Li H, Shang S, Liu F. lncRNA KCNQ1OT1 reverses the effect of sevoflurane on hepatocellular carcinoma progression via regulating the miR-29a-3p/CBX3 axis. ACTA ACUST UNITED AC 2021; 54:e10213. [PMID: 34008749 PMCID: PMC8130105 DOI: 10.1590/1414-431x2020e10213] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Accepted: 11/25/2020] [Indexed: 12/22/2022]
Abstract
Sevoflurane (SEVO) is widely applied as an anesthetic, which exerts antitumor capacity in various cancers, including hepatocellular carcinoma (HCC). Previous studies indicated that long non-coding RNA KCNQ1 opposite strand/antisense transcript 1 (KCNQ1OT1) was upregulated, while microRNA-29a-3p (miR-29a-3p) was downregulated in HCC. Thus, we aimed to explore the roles of KCNQ1OT1 and miR-29a-3p in HCC cells exposed to SEVO. Cell proliferation, apoptosis, migration, and invasion were assessed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, flow cytometry, and transwell assays, respectively. The levels of genes were determined by quantitative real-time polymerase chain reaction (qRT-PCR) or western blot. Furthermore, the interaction between miR-29a-3p and KCNQ1OT1 or chromebox protein homolog 3 (CBX3) was predicted by Starbase or Targetscan, and then confirmed by dual-luciferase reporter assay. We found that the levels of KCNQ1OT1 and CBX3 were decreased, while miR-29a-3p was increased in SEVO-treated HCC cells. KCNQ1OT1 overexpression weakened the inhibitory effects of SEVO on HCC cell proliferation, apoptosis, migration, and invasion. Interestingly, KCNQ1OT1 bound to miR-29a-3p, and miR-29a-3p targeted CBX3. KCNQ1OT1 upregulated CBX3 level by repressing miR-29a-3p expression. Furthermore, KCNQ1OT1 exerted tumor promotion in HCC cells via suppressing miR-29a-3p to regulate CBX3 expression. Collectively, our findings demonstrated that KCNQ1OT1 regulated the antitumor effects of SEVO on HCC cells through modulating the miR-29a-3p/CBX3 axis, providing a theoretical basis for the treatment of HCC.

Abstract
Neuroblastoma (NB) is a heterogeneous developmental tumor occurring in childhood, which arises from the embryonic sympathoadrenal cells of the neural crest. Although the recent progress that has been done on this tumor, the mechanisms involved in NB are still partially unknown. Despite some genetic aberrations having been identified, the sporadic cases represent the majority. Due to its wide heterogeneity in clinical behavior and etiology, NB represents a challenge in terms of prevention and treatment. Since a definitive therapy is lacking so far, there is an urgent necessity to unveil the molecular mechanisms behind NB onset and progression to develop new therapeutic approaches. Long non-coding RNAs (lncRNAs) are a group of RNAs longer than 200 nucleotides. Whether lncRNAs are destined to become a protein or not, they exert multiple biological functions such as regulating gene expression and functions. In recent decades, different research has highlighted the possible role of lncRNAs in the pathogenesis of many diseases, including cancer. Moreover, lncRNAs may represent potential markers or targets for diagnosis and treatment of diseases. This mini-review aimed to briefly summarize the most recent findings on the involvement of some lncRNAs in NB disease by focusing on their mechanisms of action and possible role in unveiling NB onset and progression.

[PMID: 33598394 PMCID: PMC7868993 DOI: 10.1016/j.jbo.2021.100348] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 12/12/2020] [Accepted: 01/05/2021] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Osteosarcoma is a primary cause of cancer-associated death in children and adolescents worldwide. Long non-coding RNAs SNHG16 (lncRNA SNHG16) and integrin subunit-a 6 (ITGA6) are recently reported to be involved in the tumorigenesis of osteosarcoma by multiple mechanisms. However, the correlation between SNHG16 and ITGA6 in osteosarcoma remains undetermined. METHODS Expression of miR-488, SNHG16 and ITGA6, as well as epithelial-mesenchymal transition (EMT) associated markers in osteosarcoma tissues and cell lines were examined by qRT-PCR or Western blotting. Effects of miR-488, SNHG16 and ITGA6 on cell migration, invasion were evaluated by wound-healing assay and transwell assay. Bioinformatics analysis and dual-luciferase reported assays were applied to assess the interaction among miR-488, SNHG16 and ITGA6. RNA immunoprecipitation (RIP) was also used to verify SNHG16 and miR-488 interaction. Finally, animal study was used to detect the effect of SNHG16 on osteosarcoma in vivo. RESULTS SNHG16 and ITGA6 were significantly increased while miR-488 was decreased in osteosarcoma. ITGA6 was screened as a target gene of miR-488, and SNHG16 was sponged by miR-488 in osteosarcoma cells. MiR-488 overexpression and SNHG16 knockdown suppressed migration, invasion and EMT of osteosarcoma cells. Moreover, rescue assays proved that the influences of SNHG16 on osteosarcoma cells migration, invasion and EMT were dependent on miR-488 and ITGA6. In addition, the promotive effects of SNHG16 on osteosarcoma tumor growth and metastasis were further supported by xenograft tumor growth assay. CONCLUSION SNHG16 promoted migration, invasion and EMT of osteosarcoma by sponging miR-488 to release ITGA6.

Abstract
Osteosarcoma (OS) is a musculoskeletal malignancy that originates from interstitial cells. An increasing number of studies have verified that long non-coding RNAs (lncRNAs) participate in the progression of numerous types of cancer. It has been reported that LINC00467 is a cancer-promoting gene in some types of cancer; however, the regulatory mechanism of LINC00467 in OS remains unknown. In the present study, reverse transcription-quantitative PCR was used to determine LINC00467 expression in OS tissues and cells. Additionally, the impact of LINC00467-knockdown on OS cell proliferation, migration and invasion was analyzed using Cell Counting Kit-8, colony formation and Transwell assays, as well as western blot analysis. RNA pulldown and luciferase reporter assays were conducted to investigate the regulatory mechanism of LINC00467 in OS. The results delineated that LINC00467 expression was elevated in OS tissues and cells, and that high LINC00467 expression was associated with a poor prognosis in patients with OS. LINC00467 inhibition suppressed OS progression by inhibiting cell proliferation, migration, invasion and epithelial-mesenchymal transition. LINC00467 served as a molecular sponge for microRNA (miR)-217, while karyopherin subunit α4 (KPNA4) was a downstream target gene of miR-217. Moreover, the overexpression of KPNA4 reversed the inhibitory effects of LINC00467 inhibition on OS progression. Therefore, the present study elucidated the potential mechanism of LINC00467 in OS and indicated that LINC00467 exerted its carcinogenic effects on OS through the miR-217/KPNA4 axis, implying that LINC00467 may be a novel potential therapeutic target for OS.

Silencing long noncoding RNA colon cancer-associated transcript-1 upregulates microRNA-34a-5p to promote proliferation and differentiation of osteoblasts in osteoporosis. Cancer Gene Ther 2021; 28:1150-1161.

Abstract
Long noncoding RNAs (lncRNAs) have been revealed to be related to multiple physiological and pathology processes such as development, carcinogenesis, and osteogenesis. It is reported that lncRNAs might exert function in osteoblast differentiation and bone formation. Here, we determined this study to clarify whether lncRNA CCAT1 could regulate osteoblast proliferation and differentiation in ovariectomized rats with osteoporosis. The osteoporosis models were established by bilateral ovariectomy and treated with CCAT1 siRNAs to discuss the effect of CCAT1 on pathological changes and osteocyte apoptosis in ovariectomized rats with osteoporosis. The osteoblasts from ovariectomized rats were cultured in vitro, which were then treated with CCAT1 siRNAs to explore the role of CCAT1 in osteoblast proliferation and differentiation. Moreover, the relationships among CCAT1, miR-34a-5p, and SMURF2 were confirmed. CCAT1 and SMURF2 were amplified while miR-34a-5p expression was inhibited in bone tissues and osteoblasts of ovariectomized rats with osteoporosis. Inhibited CCAT1 improved pathology and restricted osteocyte apoptosis of bone tissues in ovariectomized rats with osteoporosis in vivo, and also enhanced differentiation, mineralization abilities, and proliferation, and suppressed apoptosis of osteoblasts from ovariectomized rats in vitro through upregulating miR-34a-5p expression. LncRNA CCAT1 could competitively bind with miR-34a-5p to prevent the degradation of its target gene SMURF2. Results of this research suggested that the CCAT1 inhibits the proliferation and differentiation of osteoblasts in rats with osteoporosis by binding to miR-34a-5p, providing novel biomarkers for osteoporosis treatment.

Abstract
MicroRNAs (miRNAs) are a class of short non-coding RNAs of approximately 22 nucleotides in length, which function by binding to the 3' UTR sequences of their target mRNAs. It has been reported that dysregulated miRNAs play pivotal roles in numerous diseases, including cancers, such as gastric, breast, colorectal, ovarian, and other cancers. Recent research efforts have been devoted to translating these basic discoveries into clinical applications that could improve the therapeutic outcome in patients with cancer. Early studies have shown that miR-340 may act either as an oncogene or a tumor suppressor by targeting genes related to proliferation, apoptosis, and metastasis, as well as those associated with diagnosis, treatment, chemoresistance, and prognosis. miR-340 has been shown to have a role in other diseases, such as autoimmune diseases, acute stroke, and alcoholic steatohepatitis. Nevertheless, the roles of miR-340 in human malignancies are still unclear, and the associated mechanisms are complex, involving a variety of signaling pathways, such as Wnt/β-catenin and the JAK-STAT pathways. Herein, we review the crucial roles of miR-340 in human cancers through the analysis of the latest research studies, with the aim of clarifying miR-340 function in malignant disease diagnosis, treatment, and prognosis, and to propose further investigations.

Abstract
INTRODUCTION Neuroblastoma (NB) is the prime cancer of infancy, and accounts for 9% of pediatric cancer deaths. While children diagnosed with clinically stable NB experience a complete cure, those with high-risk disease (HR-NB) do not recover, despite intensive therapeutic strategies. Development of novel and effective targeted therapies is needed to counter disease progression, and to benefit long-term survival of children with HR-NB. AREAS COVERED Recent studies (2017-2020) pertinent to NB evolution are selectively reviewed to recognize novel and effective therapeutic targets. The prospective and promising therapeutic targets/strategies for HR-NB are categorized into (a) targeting oncogene-like and/or reinforcing tumor suppressor (TS)-like lncRNAs; (b) targeting oncogene-like microRNAs (miRs) and/or mimicking TS-miRs; (c) targets for immunotherapy; (d) targeting epithelial-to-mesenchymal transition and cancer stem cells; (e) novel and beneficial combination approaches; and (f) repurposing drugs and other strategies in development. EXPERT OPINION It is highly unlikely that agents targeting a single candidate or signaling will be beneficial for an HR-NB cure. We must develop efficient drug deliverables for functional targets, which could be integrated and advance clinical therapy. Fittingly, the looming evidence indicated an aggressive evolution of promising novel and integrative targets, development of efficient drugs, and improvised strategies for HR-NB treatment.

Abstract
Background: Osteosarcoma (OS) is a malignant tumor disease with high morbidity and mortality in children and adolescents. Recently, attention has been focused on the effects of long noncoding RNAs (lncRNAs) on tumor biology. In this study, we identified the role of lnc-SERTAD2-3 in the development of OS. Materials and Methods: Sixty OS samples and adjacent tissues were collected to determine the relationship between lnc-SERTAD2-3 levels and clinicopathological characteristics. Quantitative real-time PCR (qPCR) was used to measure gene expression levels. A transwell invasion assay, a Cell Counting Kit-8 assay, and flow cytometry were used to measure cell migration, growth, and apoptosis, respectively. The binding site between the lnc-SERTAD2-3 and miR-29c RNAs was evaluated using a luciferase reporter assay. Results: The expression of the lnc-SERTAD2-3 was significantly downregulated in OS samples and three OS cell lines (MG-63, U2OS, and Saos-2) compared to normal tissue. Patients with lower levels of lnc-SERTAD2-3 expression had a more unfavorable prognosis (larger OS size, distant metastasis, and recurrence). Overexpression of lnc-SERTAD2-3 inhibited proliferation and migration, and promoted apoptosis in OS cells. Moreover, we found that lnc-SERTAD2-3 could suppress miR-29c by direct binding. Moreover, reexpression of miR-29c reversed the effect of lnc-SERTAD2-3 on OS cells. Conclusion: Overall, lnc-SERTAD2-3, an OS suppressor, is involved in the inhibition of OS proliferation and migration by targeting miR-29c.

Abstract
Background Long non-coding RNAs (lncRNAs) function as a class of significant mediators in prostate cancer (PCa), and this study mainly discussed the molecular mechanism of lncRNA growth arrest-specific 5 (GAS5) in PCa progression and radiosensitivity. Materials and Methods GAS5 and microRNA-320a (miR-320a) levels were determined by quantitative real-time polymerase chain reaction (qRT-PCR). Cell viability and migration were severally examined through 3-(4, 5-dimethylthiazol-2-y1)-2, 5-diphenyl tetrazolium bromide (MTT) and transwell assays. PCa cells were treated with X-ray irradiation. Cell survival and apoptosis rate were assayed using colony formation assay and flow cytometry, respectively. The apoptosis-related protein and Rab GTPase 21 (RAB21) protein levels were measured by Western blot. The relation between miR-320a and GAS5 or RAB21 was assessed via the dual-luciferase reporter assay. The effect of GAS5 on radiosensitivity of PCa in vivo was evaluated by xenotransplantation assay. Results GAS5 was down-regulated in PCa tissues and cells. GAS5 overexpression suppressed cell viability and migration while facilitated radiosensitivity of PCa cells. GAS5 was a molecular sponge of miR-320a. The effects of GAS5 up-regulation on PCa cells were accomplished by sponging miR-320a. MiR-320a targeted RAB21 and GAS5 up-regulated RAB21 expression via targeting miR-320a. RAB21 knockdown reversed the effects of miR-320a inhibition on PCa cells. GAS5 promoted the radiosensitivity of PCa by the miR-320a/RAB21 axis in vivo. Conclusion Collectively, GAS5 restrained tumor development and expedited the radiosensitivity in PCa by the miR-320a/RAB21 axis, which provided a molecular regulatory mechanism of GAS5/miR-320a/RAB21 in PCa development and radioresistance.

Abstract
Long non-coding RNAs (lncRNAs) represent an important class of RNAs comprising more than 200 nucleotides, which are produced by RNA polymerase II. Although lacking an open reading framework and protein-encoding activity, lncRNAs can mediate endogenous gene expression by serving as chromatin remodeler, transcriptional or post-transcriptional modulator, and splicing regulator during gene modification. In recent years, increasing evidence shows the significance of lncRNAs in many malignancies, with vital roles in tumorigenesis and cancer progression. Moreover, lncRNAs were also considered potential diagnostic and prognostic markers in cancer. The lncRNA small nuclear RNA host gene 16 (SNHG16), found on chromosome 17q25.1, represents a novel tumor-associated lncRNA. SNHG16 was recently found to exhibit dysregulated expression in a variety of malignancies. There are growing evidence of SNHG16's involvement in characteristics of cancer, including proliferation, apoptosis, together with its involvement in chemoresistance. In addition, SNHG16 has been described as a promising diagnostic and prognostic biomarker in cancer patients. The current review briefly summarizes recently reported findings about SNHG16 and discuss its expression, roles, mechanisms, and diagnostic and prognostic values in human cancers.

Abstract
Osteosarcoma (OS) is one of the most primary bone malignancies, often occurring in adolescents or children. Numerous scientific findings have introduced that long noncoding RNAs (lncRNAs) can be involved in tumor occurrence and development. Although DSCAM-AS1 has been studied in several cancers, its role and mechanism in OS are poorly understood. In this work, high level of DSCAM-AS1 was validated in OS cell lines. Depleting DSCAM-AS1 inhibited cell proliferation, migration and EMT process in OS. Subsequently, we disclosed that DSCAM-AS1 was mainly observed in the cytoplasm of OS cells and could bind with miR-186-5p in OS. Moreover, inhibiting miR-186-5p rescued the impact of silenced DSCAM-AS1 on OS progression. Additionally, GPRC5A was verified as the target downstream of miR-186-5p, and it was negatively modulated by miR-186-5p but positively regulated by DSCAM-AS1. More importantly, DSCAM-AS1 enhanced GPRC5A level in OS by sequestering miR-186-5p. Finally, up-regulating GPRC5A reversed the influences of DSCAM-AS1 repression on the oncogenic behaviors of OS cells. Knockdown of DSCAM-AS1 suppressed NPC tumor growth in vivo. All findings uncovered that DSCAM-AS1 aggravated OS progression through sponging miR-186-5p to up-regulate GPRC5A expression. Thus, we proposed DSCAM-AS1 as a probable target for OS treatment.

Abstract
Introduction: Long noncoding RNA ADAMTS9-AS2 (lncRNA ADAMTS9-AS2) has critical function in tumor growth and drug resistance of various cancers. However, the role and mechanism of lncRNA ADAMTS9-AS2 in osteosarcoma (OS) is still unclear. Methods: The expression of lncRNA ADAMTS9-AS2 and MicroRNAs-130a-5p (miR-130a-5p) was detected by real-time polymerase chain reaction (RT-qPCR) experiment. In addition, we used the plasmids transfection to construct the lncRNA ADAMTS9-AS2 overexpressed OS cell lines. Subsequently, the cell proliferation ability and the sensitivity to paclitaxel (PTX) in OS cells upon up-regulating lncRNA ADAMTS9-AS2 expression were analyzed via CCK-8 assay, while Western blotting experiment was performed to detect the regulatory mechanism. Results: We found that lncRNA ADAMTS9-AS2 was down-regulated in OS tissues, and the OS patients with lncRNA ADAMTS9-AS2 downexprssion were usually accompanied with a poor prognosis. Subsequently, we discovered that up-regulation of lncRNA ADAMTS9-AS2 inhibited cell proliferation and increased the sensitivity to PTX in OS cells. Interestingly, the Western blot results showed that overexpression of lncRNA ADAMTS9-AS2 could lead to PTEN expression increased, with PI3K and p-AKT expression decreased, indicating that lncRNA ADAMTS9-AS2 could increase the OS cell sensitivity to PTX via regulating PTEN-PI3K/AKT pathway. Furthermore, we identified MicroRNAs-130a-5p (miR-130a-5p) as the downstream target gene of lncRNA ADAMTS9-AS2, which was further confirmed by the luciferase reporter assay. More importantly, our data revealed that miR-130a-5p mimics could partly reverse the influence on cell proliferation and drug sensitivity induced by lncRNA ADAMTS9-AS2 overexpression. Conclusion: LncRNA ADAMTS9-AS2 exerts its anti-carcinogenesis function by sponging miR-130a-5p, which might be a new therapeutic target for OS treatment.

Abstract
Background Thyroid cancer is a very common endocrine cancer worldwide. How long noncoding RNA (lncRNA) regulates thyroid cancer is elusive. LncRNA MFI2-AS1 has been demonstrated to initiate colorectal cancer. Nevertheless, the role of MFI2-AS1 in thyroid cancer remains unknown. This study aims to determine the roles of MFI2-AS1 in thyroid cancer. Methods qRT-PCR was used to determine the expression of MFI2-AS1 in thyroid cancer tissues and cells. Proliferation was determined by using CCK8 and colony formation assays. Transwell assay was utilized to analyze migration and invasion. Luciferase reporter assay was performed to confirm the interaction between MFI2-AS1 and miR-125a-5p. Results MFI2-AS1 was shown to be highly expressed in thyroid cancer tissues and predicted poor prognosis. Knockdown of MFI2-AS1 inhibited proliferation, colony formation, migration and invasion of thyroid cancer cells in vitro. Bioinformatics screening identified MFI2-AS1 as the sponge for miR-125a-5p. And miR-125a-5p was further confirmed to target TRIAP1 directly. Our data further demonstrated that MFI2-AS1 promoted TRIAP1 expression via repressing miR-125a-5p. Finally, TRIAP1 was found to be upregulated in thyroid cancer tissues and its restoration reversed the effects of MFI2-AS1 depletion. Conclusion Our results elucidated a novel mechanism that MFI2-AS1 promotes thyroid cancer progression via the miR-125a-5p/TRIAP1 pathway.

Abstract
Background Paclitaxel (PTX) occupies a considerable status in the chemotherapies of breast cancer (BC), but the drug resistance keeps an obstructive factor of PTX treatment. This study was designed to explore the molecular mechanism of long non-coding RNA (lncRNA) urothelial carcinoma-associated 1 (UCA1) in PTX resistance of BC. Methods UCA1, microRNA-613 (miR-613) and cyclin-dependent kinase 12 (CDK12) expression was assayed through quantitative real-time polymerase chain reaction (qRT-PCR). Cell Counting Kit-8 (CCK-8) assay was implemented for evaluating the half inhibitory concentrations (IC50) of PTX and cell viability. Cell apoptosis was examined by flow cytometry. The target relationship was explored using dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. CDK12 protein level was detected through Western blot. Xenograft tumor assay was applied for assessing the influence of UCA1 on PTX resistance of BC in vivo. Results UCA1 expressed highly in PTX-resistant BC tissues and cells and regulated PTX resistance in BC cells by affecting cell viability and apoptosis in part. UCA1 negatively interacted with miR-613 and modulated PTX resistance via sponging miR-613. CDK12 was a downstream gene of miR-613 and miR-613 exerted the modulation of PTX resistance via targeting CDK12. Furthermore, UCA1 regulated CDK12 level through interacting with miR-613. The regulatory role of UCA1 in PTX resistance of BC was achieved by miR-613/CDK12 axis in vivo. Conclusion UCA1 mediated PTX resistance in BC through the miR-613/CDK12 axis, manifesting that UCA1 might improve the PTX treatment of BC as a significant therapeutic biomarker.

Abstract
Purpose ASB16 antisense RNA 1 (ASB16-AS1) is a cancer-associated long non-coding RNA that contributes to tumorigenesis and tumor development. Nevertheless, to the best of our knowledge, whether and how ASB16-AS1 is implicated in osteosarcoma (OS) malignancy remains unclear and therefore warrants exploration. Our current study focused on making in-depth investigation of ASB16-AS1 in OS. In the present study, the expression pattern of ASB16-AS1 in OS tissues and cell lines was analyzed. In addition, we examined the clinical value of ASB16-AS1 for OS patients. Furthermore, we explored the impacts of ASB16-AS1 on the malignant phenotype of OS cells in vitro and in vivo as well as the underlying mechanism. Methods ASB16-AS1, microRNA-760 (miR-760) and hepatoma-derived growth factor (HDGF) expressions were measured using reverse transcription-quantitative PCR. Cell proliferation and apoptosis were evaluated using CCK-8 and flow cytometry analyses, respectively, and cell migration and invasion were determined via cell migration and invasion assays. Results ASB16-AS1 expression was significantly elevated in OS tissues and cell lines, and increased ASB16-AS1 expression was related to patients' tumor size, TNM stage, and distant metastasis. The overall survival rate of OS patients presenting high ASB16-AS1 expression was shorter than that of patients presenting low ASB16-AS1 expression. Reduced ASB16-AS1 expression inhibited OS cell proliferation, migration, and invasion; promoted cell apoptosis; and impaired tumor growth in vivo. Mechanistically, ASB16-AS1 served as a sponge for miR-760 and positively modulated the expression of its target HDGF. Finally, inhibiting miR-760 and restoring HDGF expression abolished the impacts of ASB16-AS1 knockdown on the malignant characteristics of OS cells. Conclusion ASB16-AS1 is a novel oncogenic lncRNA in OS cells. ASB16-AS1 increased HDGF expression by sponging miR-760, thereby conferring cancer-promoting roles in OS. ASB16-AS1 is a potential early diagnostic and therapeutic target in OS.

Abstract
Background Long non-coding RNAs (lncRNAs) play crucial roles in the regulation and treatment of multiple myeloma (MM). The objective of this research was to study the functional mechanism of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in MM. Methods MALAT1, microRNA-1271-5p (miR-1271-5p), and SRY-Box 13 (SOX13) levels were examined by quantitative real-time polymerase chain reaction (qRT-PCR). Cell viability, apoptosis, and invasion were respectively assayed using 3-(4, 5-dimethylthiazol-2-y1)-2, 5-diphenyl tetrazolium bromide (MTT), flow cytometry, and transwell assay. Glycolysis was evaluated by glucose consumption, lactate production, ATP/ADP ratio, and the detection of related enzymes. Associated proteins were measured using Western blot. Target relation was verified via dual-luciferase reporter assay. Xenograft tumor assay was implemented to study the influence of MALAT1 on MM in vivo. Results The up-regulation of MALAT1 and the down-regulation of miR-1271-5p were found in MM serums and cells. MALAT1 knockdown suppressed cell viability, invasion, and glycolysis while expedited cell apoptosis in MM cells. MALAT1 directly targeted miR-1271-5p and miR-1271-5p depression reverted the effects of MALAT1 knockdown on MM cells. SOX13 was a target of miR-1271-5p and SOX13 overexpression weakened the effects of miR-1271-5p on MM. MALAT1 indirectly modulated SOX13 expression through targeting miR-1271-5p. MALAT1 down-regulation inhibited MM growth by miR-1271-5p/SOX13 axis in vivo. Conclusion LncRNA MALAT1 expedited MM tumorigenesis, invasion, and glycolysis via miR-1271-5p/SOX13 axis. MALAT1 might contribute to the therapy of MM as a promising indicator.

Abstract
Background Neuroblastoma (NB) is a heterogeneous pediatric malignant tumor with many biological and clinical characteristics. Long non-coding RNA small nucleolar RNA host gene 16 (SNHG16) plays vital role in the development of NB. However, the potential mechanism of SNHG16 in the progression of NB is rarely reported. Methods The expression levels of SNHG16, miR-542-3p and autophagy-related gene 5 (ATG5) were measured with quantitative real-time polymerase chain reaction (qRT-PCR). The proliferation, migration and invasion of NB cells were determined using 3-(4, 5-dimethylthiazol-2-YI)-2, 5-diphenyltetrazolium bromide (MTT) or transwell assay. Protein levels of ATG5, microtubule-associated protein A1/1B-light chain3 (LC3-I/II) and p62 were detected by Western blot analysis. The interaction between miR-542-3p and SNHG16 or ATG5 was predicted by starBase and confirmed by dual luciferase reporter assay. Xenograft mice models were constructed to confirm the role of SNHG16 in vivo. Results SNHG16 was upregulated in NB tissues and cells and associated with clinical stage and poor prognosis of NB. Knockdown of SNHG16 impeded proliferation, migration, invasion and autophagy of NB cells in vitro, and suppressed tumor growth in vivo. Interestingly, SNHG16 mediated ATG5 expression through sponging miR-542-3p in NB cells. Moreover, miR-542-3p downregulation reversed the inhibitory effects of SNHG16 silencing on proliferation, migration, invasion and autophagy of NB cells. Besides, ATG5 overturned the regulatory effects on proliferation, migration, invasion and autophagy of NB cells induced by SNHG16 or miR-542-3p knockdown. Conclusion SNHG16 facilitated proliferation, migration, invasion and autophagy of NB cells via sponging miR-542-3p and upregulating ATG5 expression in NB.

Abstract
Osteosarcoma (OS) is one of the most common types of malignant tumors characterized by uncontrolled proliferation ability and acquired drug resistance. The previous study indicated that lncRNA KRAL participated in the reversal of 5-FU resistance in liver cancer, but it remains unclear whether lncRNA KRAL involved in doxorubicin (DOX) resistance of osteosarcoma. The expression of lncRNA KRAL and MicroRNAs-141 (miR-141) were detected by RT-qPCR experiment. Also, we used the plasmids transfection to construct the lncRNA KRAL overexpressed OS cell lines. Subsequently, the cell proliferation ability and the sensitivity to DOX in OS cells upon upregulating lncRNA KRAL expression were analyzed via CCK-8 and EDU assay, while western blotting experiment was performed to detect the regulatory mechanism. We found that lncRNA KRAL was downregulated in OS tissues, and the OS patients with OS patients with lower expression of lncRNA KRAL were more likely to have advanced Enneking stage, larger tumor size and distant metastasis. Subsequently, we discovered that upregulation of lncRNA KRAL could inhibit cell proliferation and increase the sensitivity to DOX of OS cells. Interestingly, the western blot results showed that over-expression of lncRNA KRAL could lead to down-expression of P-gp protein and reversal of Epithelial–mesenchymal transition (EMT) pathway. Furthermore, we identified miR-141 as the downstream target gene of lncRNA KRAL, which was further confirmed by the luciferase reporter assay. More importantly, our data demonstrated that addition of miR-141 could reverse cell proliferation and drug sensitivity of lncRNA KRAL-overexpressed OS cells. LncRNA KRAL could suppress cell growth and increases sensitivity to DOX in OS cells by sponging miR-141.

Abstract
Long noncoding RNAs (lncRNAs) have recently been considered as central regulators in diverse biological processes controlling tumorigenesis. Small nucleolar RNA host gene 16 (SNHG16) is an important tumor-associated lncRNA mainly involved in tumorigenesis and progression by competing with endogenous RNA (ceRNA) which sponges tumor-suppressive microRNA (miRNA), and by its recruitment mechanism. SNHG16 is overexpressed in tumor tissues and cell lines of different kinds of cancers, and its presence is associated with a poor clinical prognosis. Reviewing all publications about SNHG16 revealed that it plays a key role in the different hallmarks that define human cancer, including promoting proliferation, activating migration and invasion, inhibiting apoptosis, affecting lipid metabolism and chemoresistance. This review highlights the role that the aberrant expression of SNHG16 plays in the development and progression of cancer, and suggests that SNHG16 may function as a potential biomarker and therapeutic target for human cancers.

Abstract
A growing body of evidence suggests that long non-coding RNAs (lncRNAs), a novel class of non-coding endogenous single-stranded RNA, play a key role in multiple physiological and pathological processes through transcriptional interference, post-transcriptional regulation, and epigenetic modification. Furthermore, many studies have shown that lncRNAs-as oncogenes or tumour suppressors-play an important role in the occurrence and development of human cancers. Small nucleolar RNA host gene 16 (SNHG16) was initially identified as an oncogenic lncRNA in neuroblastoma, and has since been identified as a carcinogenic regulator of various malignant tumours. Overexpression of SNHG16 is associated with clinical and pathological characteristics of cancer patients, and regulates cell proliferation, apoptosis, invasion and metastasis through a variety of potential mechanisms. Therefore, SNHG16 may be a promising biomarker and therapeutic target for cancers. In this review, we summarize the biological function, related mechanisms and potential clinical significance of SNHG16 in multiple human cancers.

Abstract
BACKGROUND Pneumonia is an infectious lung inflammation in children with high mortality and morbidity rates. Small nucleolar RNA host gene 16 (SNHG16) has been verified to accelerate the progression of acute pneumonia. However, the role of SNHG16 in acute pneumonia has not yet been fully elucidated. The study was aimed to explore the regulatory mechanism of SNHG16 in LPS-induced acute pneumonia in A549 cells. METHODS The levels of SNHG16, miR-370-3p and IGF2 in serum samples and LPS-induced A549 cells were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The cell viability and apoptosis of A549 cells were examined by Cell Counting Kit-8 (CCK-8) assay and flow cytometer, respectively. The levels of interleukin 1β (IL-1β), interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were determined by enzyme-linked immunosorbent assay (ELISA). The binding relationships among SNHG16, miR-370-3p and IGF2 were predicted by online database and verified by Dual-luciferase reporter and RNA immunoprecipitation (RIP) assays. The protein levels of IGF2 were tested by Western blot. RESULTS SNHG16 and IGF2 were upregulated while miR-370-3p was downregulated in serum of acute pneumonia patients and LPS-induced A549 cells. SNHG16 regulated proliferation, apoptosis and inflammatory cytokines by inhibiting miR-370-3p in LPS-induced A549 cells. MiR-370-3p targeted IGF2 and inhibited LPS-induced inflammatory injury via IGF2 in A549 cells. Furthermore, SNHG16 was verified to promote IGF2 expression by sponging miR-370-3p in A549 cells. CONCLUSION SNHG16 impeded cell viability and promoted apoptosis, inflammatory injury by targeting IGF2 mediated by miR-370-3p in LPS-induced A549 cells.

Abstract
Endometrial cancer (EC) is deemed to be the most typical gynecologic malignant tumor. Despite the incidence of EC being lower in Asia than that in western countries, substantial increased incidence has been observed in the past few decades in Asia. Although various molecular testing methods and genomic science have developed, the overall prognosis is still disappointing. LncRNAs have been found to influence the progression of various cancers. CHL1-AS1 has been found to be upregulated in ovarian endometriosis, nevertheless, the molecular mechanism and biological function of CHL1-AS1 in EC have not been explored. In our exploration, both CHL1-AS1 and CHL1 were upregulated in EC cells. Knockdown of CHL1-AS1 or CHL1 inhibited cell proliferation and migration in EC. Furthermore, microRNA-6076 (miR-6076) could bind with CHL1-AS1 or CHL1, and regulate the expression of CHL1. Finally, absence of miR-6076 or overexpression of CHL1 can partially rescue the effect of CHL1-AS1 knockdown or miR-6076 upregulation on cell proliferation and migration, respectively. All in all, our research was the first endeavor to study the underlying mechanism of CHL1-AS1 in EC and confirmed that CHL1-AS1 regulated EC progression via targeting the miR-6076/CHL1 axis, offering new insight into treating EC.

Abstract
Pediatric solid tumors are a diverse group of extracranial solid tumors representing approximately 40% of childhood cancers. Pediatric solid tumors are believed to arise as a result of disruptions in the developmental process of precursor cells which lead them to accumulate cancerous phenotypes. In contrast to many adult tumors, pediatric tumors typically feature a low number of genetic mutations in protein-coding genes which could explain the emergence of these phenotypes. It is likely that oncogenesis occurs after a failure at many different levels of regulation. Non-coding RNAs (ncRNAs) comprise a group of functional RNA molecules that lack protein coding potential but are essential in the regulation and maintenance of many epigenetic and post-translational mechanisms. Indeed, research has accumulated a large body of evidence implicating many ncRNAs in the regulation of well-established oncogenic networks. In this review we cover a range of extracranial solid tumors which represent some of the rarer and enigmatic childhood cancers known. We focus on two major classes of ncRNAs, microRNAs and long non-coding RNAs, which are likely to play a key role in the development of these cancers and emphasize their functional contributions and molecular interactions during tumor formation.

Long noncoding RNA TTN-AS1 enhances the malignant characteristics of osteosarcoma by acting as a competing endogenous RNA on microRNA-376a thereby upregulating dickkopf-1. Aging (Albany NY) 2019; 11:7678-7693.

Abstract
The expression levels and detailed functions of TTN-AS1 in osteosarcoma (OS) have not yet been explored. This study aimed to measure TTN-AS1 expression in OS tissues and cell lines, investigate its specific roles in the aggressive characteristics of OS cells in vitro and in vivo, and elucidate the regulatory mechanisms of TTN-AS1 action. TTN-AS1 expression was high in OS tissue samples and cell lines; TTN-AS1 overexpression correlated with the clinical stage, distant metastasis, and shorter overall survival of the patients. A TTN-AS1 knockdown inhibited OS cell proliferation, migration, and invasion and induced apoptosis in vitro and slowed tumor growth in vivo. Mechanism investigation revealed that TTN-AS1 acts as a competing endogenous RNA on microRNA-376a-3p (miR-376a) in OS cells. Dickkopf-1 (DKK1) mRNA was identified as a direct target of miR-376a in OS cells. Resumption of DKK1 expression reversed the tumor-suppressive activities of miR-376a overexpression in OS cells. The knockdown of miR-376a counteracted the reduction in the malignant characteristics of OS cells by the downregulation of TTN-AS1. In conclusion, TTN-AS1 functions as a competing endogenous RNA targeting miR-376a and increases the malignancy of OS cells in vitro and in vivo by upregulating DKK1.

Abstract
OBJECTIVE To investigate the mechanism of miRNA-340 for regulating the proliferation of gastric cancer (GC) cells and predict its interacting circular RNAs (circRNAs), its downstream target genes and the involved signaling pathways. METHODS The differentially expressed miRNAs in GC cell lines were analyzed and screened using miRNA microarrays. The expression level of miRNA-340 in 21 pairs of GC tissues and adjacent normal tissues was detected using real-time PCR. MTT and EdU assays were performed to examine the effect of miRNA-340 on the proliferation ability of HFE145 and BGC-823 cells. We also tested the effect of miRNA-340 inhibition on subcutaneous tumorigenesis of GC cells in a nude mouse model. The downstream target genes of miRNA-340 and the probable signal pathways were predicted online using Targetscan and DAVID database, respectively. The interacting circRNAs of miRNA-340 were analyzed using starBase platform. RESULTS Among the differentially expressed miRNAs, miRNA-340 was significantly down-regulated in GC cell lines. Real-time PCR results showed that the expression of miRNA-340 was significantly lower in GC tissues than in the adjacent tissues (P < 0.05). MTT and EdU cell proliferation assays showed that miRNA-340 overexpression inhibited the proliferation of GC cells in vitro. In the nude mouse models, the proliferation of GC cells transfected with miRNA-340 inhibitor was obviously enhanced. Bioinformatics analysis suggested that miRNA-340 had 21 target genes with 3 or more conserved sites, and these genes were involved in tumorigenesis and invasion. The top 10 circRNAs were selected as the most powerful sponge circRNAs interacting with miRNA-340. CONCLUSIONS miRNA-340 may play the role of a tumor suppressor in tumorigenesis and progression. Overexpression of miRNA-340 suppress the proliferation of GC cells, suggesting its involvement in the development of GC along with multiple circRNAs.

Abstract
The present study investigated the role of long non‐coding RNA (lncRNA) small nucleolar RNA host gene 16 (SNHG16) in the human aortic smooth muscle cell (HASMC) proliferation and migration and explored the potential link between SNHG16 and atherosclerosis. Our results showed that platelet‐derived growth factor (PDGF)‐bb treatment promoted cell proliferation and migration with concurrent up‐regulation of SNHG16 in HASMCs. Small nucleolar RNA host gene 16 overexpression promoted HASMC proliferation and migration, while SNHG16 knockdown suppressed cell proliferation and migration in PDGF‐bb‐stimulated HASMCs. The bioinformatic analyses showed that SNHG16 possessed the complementary binding sequence with miR‐205, where the interaction was confirmed by luciferase reporter assay and RNA pull‐down assay in HASMCs, and SNHG16 inversely regulated miR‐205 expression. MiR‐205 overexpression attenuated the enhanced effects of PDGF‐bb treatment on HASMC proliferation and migration. Moreover, Smad2 was targeted and inversely regulated by miR‐205, while being positively regulated by SNHG16 in HASMCs. Smad2 knockdown attenuated PDGF‐bb‐mediated actions on HASMC proliferation and migration. Both miR‐205 overexpression and Smad2 knockdown partially reversed the effects of SNHG16 overexpression on HASMC proliferation and migration. Moreover, SNHG16 and Smad2 mRNA were up‐regulated, while miR‐205 was down‐regulated in the plasma from patients with atherosclerosis. Small nucleolar RNA host gene 16 expression was inversely correlated with miR‐205 expression and positively correlated with Smad2 expression in the plasma from atherosclerotic patients. In conclusion, our data showed the up‐regulation of SNHG16 in pathogenic‐stimulated HASMCs and clinical samples from atherosclerotic patients. Small nucleolar RNA host gene 16 regulated HASMC proliferation and migration possibly via regulating Smad2 expression by acting as a competing endogenous RNA for miR‐205.

Abstract
BACKGROUND As has been illustrated that long noncoding RNAs (lncRNAs) and microRNAs (miRNAs) are potential regulators in the occurrence and progression of human cancers. LncRNA SNHG16 has been identified as an oncogene involved in the progression of human cancers. However, neither the function nor the underlying molecular mechanism of SNHG16 in osteosarcoma has been discovered. PURPOSE The aim of the study is to explore the role and molecular regulation mechanism of SNHG16 in osteosarcoma. METHODS The expression of SNHG16 in HNSCC tissues and cells was detected by RT-qPCR assay. The biological function of SNHG16 in osteosarcoma was measured by CCK-8, cell cycle, cell apoptosis and transwell assays. The interaction between SNHG16 and miR-98-5p was studied by luciferase reporter and RIP assays. RESULTS The ectopic expression of SNHG16 was found in osteosarcoma tissues and cell lines, which indicated poor prognosis and lower overall survival rate of osteosarcoma patients. Knockdown of SNHG16 inhibited cell proliferation, migration, invasion, cell cycle and promoted apoptosis in osteosarcoma. It was demonstrated that SNHG16 directly interacts with miR-98-5p. What's more, we found a significantly negative correlation between SNHG16 and miR-98-5p expression. Finally, rescue experiments revealed that inhibition of miR-98-5p attenuated SNHG16 knockdown-mediated effects on cellular processes in osteosarcoma. CONCLUSIONS LncRNA SNHG16 regulated cellular processes in osteosarcoma by sponging miR-98-5p, and SNHG16 may be a new and effective molecular therapeutic target for osteosarcoma.

Abstract
Long non-coding RNAs (lncRNAs) play a key role in regulating tumor growth and metastasis of osteosarcoma (OS). Recent studies have reported that lncRNA small nucleolar RNA host gene 16 (SNHG16) is highly expressed in OS tissues and contributes to the proliferation, migration and invasion of OS cells. However, the molecular mechanism involved in the oncogenic role of SNHG16 in OS remains poorly known. In the current study, we confirmed that SNHG16 expression was markedly up-regulated in OS tissues compared to paracancerous tissues. The elevated level of SNHG16 closely associated with advanced tumor stages, larger tumor size and more distance metastasis. Furthermore, OS patients with high SNHG16 level had a significant poorer overall survival compared to patients with low SNHG16 level. Knockdown of SNHG16 suppressed the proliferation, migration and invasion of U2OS and MG63 cells. Mechanistically, SNHG16 acted as a competing endogenous RNA (ceRNA) by directly interacting with miR-1301 and inversely regulated its abundance in OS cells. Notably, suppression of miR-1301 rescued SNHG16 knockdown attenuated OS cell proliferation, migration and invasion. SNHG16 knockdown reduced the expression of BCL9 protein in OS cells. Accordingly, BCL9 restoration facilitated the proliferation, migration and invasion of OS cells with SNHG16 knockdown. Collectively, these results suggest that SNHG16 is a potential prognostic biomarker for OS patients. SNHG16 promotes BCL9 expression by sponging miR-1301 to facilitate the proliferation, migration and invasion of OS cells.
