Abstract
PURPOSE Long non-coding RNAs are an essential component of competing endogenous RNA regulatory axes and play their role by sponging microRNAs and interfering with the regulation of gene expression. Because of the broadness of competing endogenous RNA interaction networks, they may help investigate treatment targets in complicated disorders. METHODS This study performed a systematic scoping review to assess verified loops of competing endogenous RNAs in retinoblastoma, emphasizing the competing endogenous RNAs axis related to long non-coding RNAs. We used a six-stage approach framework and the PRISMA guidelines. A systematic search of seven databases was done to locate suitable papers published before February 2022. Two reviewers worked independently to screen articles and collect data. RESULTS Out of 363 records, fifty-one articles met the inclusion criteria, and sixty-three axes were identified in desired articles. The majority of the research reported several long non-coding RNAs that were experimentally verified to act as competing endogenous RNAs in retinoblastoma: XIST/NEAT1/MALAT1/SNHG16/KCNQ1OT1, respectively. At the same time, around half of the studies investigated unique long non-coding RNAs. CONCLUSIONS Understanding the many features of this regulatory system may aid in elucidating the unknown etiology of Retinoblastoma and providing novel molecular targets for therapeutic and clinical applications.

From diagnosis to therapy: The transformative role of lncRNAs in eye cancer management. Pathol Res Pract 2024; 254:155081. [PMID: 38211388 DOI: 10.1016/j.prp.2023.155081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 12/29/2023] [Accepted: 12/30/2023] [Indexed: 01/13/2024]
Abstract
The genomic era has brought about a transformative shift in our comprehension of cancer, unveiling the intricate molecular landscape underlying disease development. Eye cancers (ECs), encompassing diverse malignancies affecting ocular tissues, pose distinctive challenges in diagnosis and management. Long non-coding RNAs (lncRNAs), an emerging category of non-coding RNAs, are pivotal actors in the genomic intricacies of eye cancers. LncRNAs have garnered recognition for their multifaceted roles in gene expression regulation and influence on many cellular processes. Many studies support that the lncRNAs have a role in developing various cancers. Recent investigations have pinpointed specific lncRNAs associated with ECs, including retinoblastoma and uveal melanoma. These lncRNAs exert control over critical pathways governing tumor initiation, progression, and metastasis, endowing them with the ability to function as evaluation, predictive, and therapeutic indicators. The article aims to synthesize the existing information concerning the functions of lncRNAs in ECs, elucidating their regulatory mechanisms and clinical significance. By delving into the lncRNAs' expanding relevance in the modulation of oncogenic and tumor-suppressive networks, we gain a deeper understanding of the molecular complexities intrinsic to these diseases. In our exploration of the genomic intricacies of ECs, lncRNAs introduce a fresh perspective, providing an opportunity to function as clinical and therapeutic indicators, and they also have therapeutic benefits that show promise for advancing the treatment of ECs. This comprehensive review bridges the intricate relationship between lncRNAs and ECs within the context of the genomic era.

Abstract
INTRODUCTION Retinoblastoma (RB) is the most common childhood tumor that can occur in the retina and develop in a sporadic or heritable form. Although various traditional treatment options have been used for patients with RB, identifying novel strategies for childhood cancers is necessary. MATERIAL AND METHODS Recently, molecular-based targeted therapies have opened a greater therapeutic window for RB. Long non-coding RNAs (lncRNAs) presented a potential role as a biomarker for the detection of RB in various stages. CONCLUSION LncRNAs by targeting several miRNA/transcription factors play critical roles in the stimulation or suppression of RB. In this review, we summarized recent progress on the functions of tumor suppressors or oncogenes lncRNAs in RB.

INFECTION, GENETICS AND EVOLUTION : JOURNAL OF MOLECULAR EPIDEMIOLOGY AND EVOLUTIONARY GENETICS IN INFECTIOUS DISEASES 2022; 103:105325. [PMID: 35779785 DOI: 10.1016/j.meegid.2022.105325] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/12/2021] [Revised: 06/23/2022] [Accepted: 06/26/2022] [Indexed: 06/15/2023]
Abstract
OBJECTIVE The study investigated the clinical diagnostic value of long non-coding RNA (LncRNA) small nucleolar RNA host gene 16 (SNHG16) and explored its underlying molecular mechanism through Mycobacterium tuberculosis (M. tuberculosiinfection of macrophages. METHODS RT-qPCR analysis of the serum SNHG16 levels of the 66 healthy individuals, 67 latent TB (LTB) patients, and 67 active TB (ATB) patients. The receiver-operating characteristic (ROC) curve to detect the clinical diagnostic value of SNHG16 in TB patients. In vitro, M. tuberculosis-infected macrophages, CCK-8 and ELISA to detect cell proliferation and inflammatory factor levels. Luciferase reported assay was performed to analyze the targeting relationship between SNHG16 and miR-140-5p. RESULTS SNHG16 was significantly elevated in TB patients, and among them, ATB patients were higher than LTB patients. ROC confirmed that SNHG16 could distinguish LTB patients from healthy controls, and ATB patients from LTB patients, and can be used as a good diagnostic biomarker for TB. M. tuberculosis infection increased SNHG16 levels and promoted the proliferation and inflammation in macrophages. However, SNHG16 silencing significantly reversed the effect of infection. miR-140-5p, a direct target miRNA of SNHG16, was down-regulated in TB patients and was negatively correlated with SNHG16. When miR-140-5p was inhibited, the alleviating effect of SNHG16 silencing on M. tuberculosis infection proliferation and inflammation was significantly reversed. CONCLUSION The present results suggested that SNHG16 may be a new diagnostic biomarker for TB patients and SNHG16 silencing may alleviate TB by inhibiting the proliferation of macrophages in TB by regulation miR-140-5p.

lncRNA FOXD2-AS1 Promotes the Retinoblastoma Cell Viability and Migration by Sponging miR-31. BIOMED RESEARCH INTERNATIONAL 2022; 2022:7723425. [PMID: 35782084 PMCID: PMC9246629 DOI: 10.1155/2022/7723425] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 05/31/2022] [Accepted: 06/08/2022] [Indexed: 02/07/2023]
Abstract
Background. The purpose of this study was to explore the functions of FOXD2-AS1 and miR-31 in retinoblastoma. Material and Methods. An RT-qPCR assay was applied to calculate the mRNA levels of FOXD2-AS1, miR-31, and PAX9. A dual-luciferase reporter gene assay was employed to verify the connection between FOXD2-AS1, miR-31, and PAX9 expression. Results. FOXD2-AS1 was upregulated, and miR-31 was lowly expressed in retinoblastoma. Low expression of FOXD2-AS1 promoted cell proliferation and migration, and upregulation of FOXD2-AS1 inhibited proliferative and migratory abilities. lncRNA FOXD2-AS1 directly bound to miR-31 and regulated miR-31 expression in SO-RB50 cells. Cell proliferation and migration were inhibited by the miR-31 mimic. miR-31 mediated PAX9 expression via directly binding to PAX9 mRNA. A miR-31 inhibitor partially reversed the effect of FOXD2-AS1 knockdown on the proliferation and migration in SO-RB50 cells. FOXD2-AS1 knockdown reduced PAX9 expression in SO-RB50 cells. PAX9 had negative connection with miR-31, and it had positive relationship with FOXD2-AS1. Conclusion. lncRNA FOXD2-AS1 inhibited cell proliferation and migration via the miRNA-31/PAX9 axis in retinoblastoma.

Abstract
This work unraveled the action of human umbilical cord mesenchymal stem cells-released exosomes (huc-MSCs-EXO) transfer of miR-140-5p in preeclampsia (PE). miR-140-5p and follistatin-like 3 (FSTL3) expression in placental tissues of PE patients was tested. EXO were isolated from huc-MSCs. Hypoxic trophoblast cells were co-cultured with huc-MSCs-EXO. Cell biological functions, angiogenesis, and inflammation were evaluated. Suppressed miR-140-5p and induced FSTL3 levels were measured in PE. Huc-MSCs-EXO drove biological functions and angiogenesis while hindering inflammation in hypoxic trophoblast cells. Increasing miR-140-5p further improved the positive role of huc-MSCs-EXO for hypoxic trophoblast cells, but the miR-140-5p-mediated effect in hypoxic trophoblast cells was abrogated by overexpressing FSTL3. miR-140-5p from huc-MSCs-EXO suppresses PE through repressing FSTL3.

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
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
Long non-coding RNA (lncRNA) TP53 target 1 (TP53TG1) is known to be strongly associated with tumor and cancer progression. However, its expression profile, unique role, and regulatory pathways in retinoblastoma (RB) are not known. Here, we revealed a large expression of TP53TG1 in RB tissues and cell lines. Conversely, we showed marked suppression of cell proliferation, migration, and invasion in TP53TG1 knocked down RB cells. Mechanistically, we established that TP53TG1 directly interacted with microRNA (miR)-33b in RB cells. Furthermore, TP53TG1 transcripts were found to be inversely correlated with miR-33b in RB tissues. We also showed that miR-33b suppression partly reversed the TP53TG1 knockdown mediated effects on tumor biology. Finally, TP53TG1 was shown to modulate the levels of SHC Binding and Spindle Associated 1 (SHCBP1), a direct target of miR-33b in RB cells. Based on the above data, we propose that TP53TG1 regulates RB progression via its modulation of the miR-33b/SHCBP1 pathway.

Abstract
MicroRNA-140 (miR-140) has been shown to be associated with the pathogenesis of a wide range of pathologies including osteoarthritis, osteoporosis, renal fibrosis, ischemic conditions, and most importantly neoplasia. This miRNA has been shown to be down-regulated in a diversity of cancers namely breast cancer, gastrointestinal cancers, lung cancer, and prostate cancer. miR-140 has a lot of immune-related targets. Moreover, several miR-140 targets regulate cell proliferation, cell cycle transition, and apoptosis. This miRNA has been shown to be sponged by a number of lncRNAs and circ-RNAs. miR-140 has essential roles in the determination of the sensitivity of neoplastic cells to chemotherapeutic agents such as temozolomide, doxorubicin, and cisplatin. Besides, expression quantities of miR-140 in cancer tissues can be used for the prediction of clinical outcomes of patients with neoplasia. In the present paper, we describe the impact of miR-140 in neoplastic and non-neoplastic disorders.

Accumulating evidence has reported the role of microRNA (miR) in retinoblastoma (RB). Therefore, the objective was to discuss how miR-362-3p exerted its function in RB cell progression via regulating ubiquitin-specific protease 2 (USP22) and lysine-specific histone demethylase 1 (LSD1). MiR-362-3p, USP22 and LSD1 expression in RB cells and tissues were tested. The biological functions of RB cells were detected via over-expressing miR-362-3p and down-regulating USP22. The target relationship of USP22 and miR-362-3p as well as the interaction of USP22 and LSD1 in RB was verified. Down-regulated miR-362-3p and up-regulated USP22 and LSD1 were demonstrated in RB tissues and cells. Restoring miR-362-3p and depleting USP22 attenuated invasion, proliferation and migration, and facilitated apoptosis of RB cells. USP22 was a target gene of miR-362-3p. USP22 deubiquitinated LSD1 in RB. It is revealed that miR-362-3p targets USP22 and then restrains invasion, proliferation and migration while promotes apoptosis of RB via reducing LSD1 modified by deubiquitination.

Abstract
Neuroblastoma is an important problem in children. Long noncoding RNAs (lncRNAs) exhibit important roles in tumorigenicity of neuroblastoma. However, the role and mechanism of lncRNA small nucleolar RNA host gene 16 (SNHG16) in neuroblastoma tumorigenicity remain poorly understood. Forty-six neuroblastoma samples and 28 normal tissues were harvested. The levels of SNHG16, microRNA-15b-5p (miR-15b-5p), and phosphoribosyl pyrophosphate synthetase 1 (PRPS1) were detected via quantitative reverse transcription PCR or western blot. Cell proliferation as well as cycle distribution were measured via 3-(4, 5-Dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide or flow cytometry. Cell metastasis was investigated via epithelial-mesenchymal transition or transwell assay. The target relationship of miR-15b-5p and SNHG16 or PRPS1 was explored via starBase and dual-luciferase reporter assay. The role of SNHG16 in neuroblastoma in vivo was analyzed using a xenograft model. We found SNHG16 and PRPS1 levels were increased in neuroblastoma tissues and cells. SNHG16 knockdown inhibited cell proliferation, increased the cell cycle distribution at G0/G1 phase, and decreased the cells at S phase. SNHG16 overexpression caused an opposite effect. SNHG16 silence suppressed neuroblastoma cell metastasis. PRPS1 knockdown constrained cell proliferation and metastasis and regulated cell cycle distribution. miR-15b-5p was sponged by SNHG16 and directly targeted PRPS1. miR-15b-5p knockdown or PRPS1 overexpression mitigated the influence of SNHG16 silence on cell cycle, proliferation, and metastasis. SNHG16 knockdown reduced xenograft tumor growth. In conclusion, SNHG16 downregulation suppressed neuroblastoma tumorigenicity by regulating cell cycle, proliferation, and metastasis via miR-15b-5p/PRPS1 axis.

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
Emerging evidences indicated that long non-coding RNAs (LncRNAs) regulated the pathogenesis of retinoblastoma (RB). However, up until now, the role of LncRNA Linc-PINT in the regulation of RB progression is still largely unknown. The present study identified LncRNA Linc-PINT as a tumor suppressor to hinder RB development by regulating miR-523-3p/Dickkopf-1 (DKK1) axis. Mechanistically, Linc-PINT was low-expressed, while miR-523-3p was high-expressed in RB cells, compared to the normal retinal epithelial cells (ARPE-19). Further gain- and loss-function experiments verified that both upregulation of Linc-PINT and miR-523-3p downregulation slowed down cell growth, invasion and migration, and promoted cell apoptosis in RB cells, but Linc-PINT ablation and miR-523-3p overexpression promoted malignant phenotypes in RB cells. In addition, the dual-luciferase reporter gene system and RNA pull-down assay validated that Linc-PINT positively regulated DKK1 expressions by sponging miR-523-3p, and Linc-PINT inhibited RB progression by regulating miR-523-3p/DKK1 axis. Functionally, we found that both miR-523-3p overexpression and DKK1 silence abrogated the anti-cancer effects of overexpressed Linc-PINT on RB cells. Finally, Linc-PINT inhibited tumorigenicity of RB cells in xenograft mice models. In general, analysis of the data suggested that Linc-PINT inhibited miR-523-3p to upregulate DKK1, resulting in the inhibition of RB, and we demonstrated that Linc-PINT and miR-523-3p could be utilized as potential diagnostic and therapeutic biomarkers for RB in clinic.

Abstract
Background: Glioma is the most common tumor of the central nervous system, which has a high mortality and recurrence rate. Increasing evidence shows that long noncoding RNAs (lncRNA) are closely related to the occurrence of cancer. However, the mechanism of lncRNA small nucleolar RNA host gene 16 (SNHG16) in glioma remains to be studied. Materials and Methods: The expression levels of SNHG16, microRNA-490 (miR-490), and poly(C)-binding proteins 2 (PCBP2) in tissues and cells were determined by quantitative real-time polymerase chain reaction. 3-(4, 5-dimethyl-2 thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) and transwell assays were used to evaluate the proliferation, migration, and invasion abilities of glioma cells. Moreover, Western blot analysis was performed to assess the levels of PCBP2 and proliferation-related and metastasis-related proteins. Dual-luciferase reporter assay was used to verify the interaction among SNHG16, miR-490, and PCBP2. Results: SNHG16 was highly expressed in glioma tissues and cells, and silenced-SNHG16 suppressed the proliferation, migration, and invasion of glioma cells. Besides, SNHG16 could interact with miR-490. The aberrant expression of SNHG16 restored the inhibitory effect of miR-490 overexpression on the proliferation, migration, and invasion of glioma cells. Moreover, PCBP2 was a target of miR-490. MiR-490 inhibitor recovered the suppression effect of PCBP2 knockdown on glioma progression, and PCBP2 overexpression also could reverse the inhibition effect of miR-490 mimic on glioma progression. In addition, SNHG16 promoted the expression of PCBP2, while miR-490 inhibited its expression. Conclusions: The authors' data revealed that SNHG16 might function as an oncogene in glioma through regulating the miR-490/PCBP2 axis, and the elucidating of the mechanism of SNHG16 provided a potential therapeutic target for glioma.

Abstract
Background Recent studies have highlighted the important role of long non-coding RNA SNHG16 in various human cancers. Here, we conducted a meta-analysis to investigate the effect of SNHG16 expression on clinicopathological features and prognosis in patients with different kinds of human cancers. Methods We performed a systematic search in electronic databases including PubMed, EMBASE, Cochrane Library and Web of Science, to investigate the potential association between SNHG16 expression and prognostic significance and clinical features in cancer patients. Odds ratios (ORs) or hazards ratios (HRs) with corresponding 95% confidence intervals (95% CIs) were pooled to estimate the prognosis value of SNHG16 by StataSE 15.0 software. Results A total of 16 eligible studies with 1299 patients were enrolled in our meta-analysis. The results revealed that increased expression level of SNHG16 was significantly associated with larger tumor size (OR: 3.357; 95% CI: 2.173–5.185; P < 0.001), advanced TNM stage (OR: 2.930; 95% CI: 1.522–5.640; P = 0.001) and poor histological grade (OR: 3.943; 95% CI: 1.955–7.952; P < 0.001), but not correlated with smoking status (P = 0.489), sex (P = 0.932), distant metastasis (P = 0.052), or lymph node metastasis (P = 0.155). Moreover, the pooled HR showed that elevated expression SNHG16 was associated with a significantly poorer overall survival (OS) (HR = 1.866, 95% CI: 1.571–2.216, P < 0.001). For the set of cancer types, high expression of SNHG16 was significantly associated with shorter OS in patients with cancers of the urinary system (HR: 2.523, 95% CI:1.540–4.133; P <0.001), digestive system (HR: 2.406, 95% CI:1.556–3.721; P <0.001), and other cancers (including glioma and non-small cell lung cancer) (HR: 1.786, 95% CI:1.406–2.267; P <0.001). Conclusions LncRNA SNHG16 overexpression might serve as an unfavorable prognostic factor, which provides a basis for medical workers to evaluate the prognosis of patients and to help the decision-making process.

LncRNA SNHG16 induces proliferation and fibrogenesis via modulating miR-141-3p and CCND1 in diabetic nephropathy. Gene Ther 2020; 27:557-566.

Abstract
LncRNAs are reported to participate in the progression of various diseases including diabetic nephropathy. Currently, we reported that SNHG16 was obviously upregulated in db/db mice and high glucose-treated mice mesangial cells. Then, functional experiments showed that SNHG16 silencing significantly inhibited proliferation of mice mesangial cells, which induced the apoptosis and triggered cell cycle arrest. Meanwhile, proliferation-related biomarkers PCNA and Cyclin D1 (CCND1) were greatly repressed. Furthermore, western blot analysis was conducted to test fibrogenesis-associated genes Fibronectin and α-SMA. Meanwhile, the increased protein expression levels of Fibronectin and α-SMA under high glucose conditions were reversed by loss of SNHG16. miR-141-3p has been reported to be involved in various diseases. Then, RNA immunoprecipitation assay revealed the relation between SNHG16 and miR-141-3p. Downregulation of SNHG16 was able to induce expression of miR-141-3p, which was obviously reduced in db/db diabetic nephropathy mice. In addition, CCND1 is a crucial cell cycle master in human diseases. CCND1 was speculated as the target of miR-141-3p and miR-141-3p inhibited CCND1 expression significantly. Meanwhile, we observed that loss of CCND1 greatly repressed mice mesangial cell proliferation and induced cell apoptosis. Taken these together, we revealed for the first time that SNHG16 induced proliferation and fibrogenesis via modulating miR-141-3p and CCND1 in diabetic nephropathy. SNHG16/miR-141-3p/CCND1 axis can suggest a pathological mechanism of progression of diabetic nephropathy.

Abstract
The mechanism by which miR‐605‐3p regulates hepatocellular carcinoma (HCC) metastasis has not been clarified. In this study, we found that miR‐605‐3p was down‐regulated in HCC and that low miR‐605‐3p expression was associated with tumour thrombus and tumour satellites. HCC patients with low miR‐605‐3p expression showed shorter overall survival and disease‐free survival after surgery. Overexpression of miR‐605‐3p inhibited epithelial‐mesenchymal transition and metastasis of HCC through NF‐κB signalling by directly inhibiting expression of TRAF6, while silencing of miR‐605‐3p had the opposite effect. We also found that SNHG16 directly bound to miR‐605‐3p as a competing endogenous RNA. Mechanistically, high expression of SNHG16 promoted binding to miR‐605‐3p and inhibited its activity, which led to up‐regulation of TRAF6 and sustained activation of the NF‐κB pathway, which in turn promoted epithelial‐mesenchymal transition and metastasis of HCC. TRAF6 increased SNHG16 promoter activity by activating NF‐κB, thereby promoting the transcriptional expression of SNHG16 and forming a positive feedback loop that aggravated HCC malignancy. Our findings reveal a mechanism for the sustained activation of the SNHG16/miR‐605‐3p/TRAF6/NF‐κB feedback loop in HCC and provide a potential target for a new HCC treatment strategy.

Abstract
A great deal of evidence suggests that long non-coding RNAs (lncRNAs) function in the tumorigenesis of retinoblastoma (RB). However, the roles of lncRNA ILF3-AS1 in RB are still unclear. In the present study, our work revealed that the lncRNA ILF3-AS1 was increased in both RB tissues and cell lines. Repression of ILF3-AS1 suppressed both RB cell proliferation and invasion in vitro. ILF3-AS1 also promoted tumor growth in vivo. While exploring the mechanisms behind ILF3-AS1 in RB, we identified that ILF3-AS1 sponges with miR-132-3p that is expressed at low levels in RB tissues as well as attenuates RB progression. Furthermore, SMAD2 was confirmed to be a miR-132-3p target. Finally, we found that SMAD2 overexpression or miR-132-3p inhibitors recover the inhibitory effects of ILF3-AS1 suppression on RB progression. Collectively, these data indicate that ILF3-AS1 is involved in RB progression through the miR-132-3p/SMAD2 axis, providing a novel and promising biomarker that can be used for the treatment of RB.

Abstract
OBJECTIVE Retinoblastoma (RB) is an uncommon childhood carcinoma of the developing retina. Long non-coding RNA (lncRNA) metastasis associated lung adenocarcinoma transcript 1 (MALAT1), microRNA-20b-5p (miR-20b-5p) and signal transducer and activator of transcription 3 (STAT3) was revealed to partake in RB. But their relationship was still to be investigated, so we intended to discuss the specific interaction of MALAT1, miR-20b-5p and STAT3 in RB. METHODS By RNA isolation and quantitation, we measured the MALAT1 expression in RB tissues and cell lines. Then, to determine the influence of MALAT1 on RB cells, RB cells were transfected with siRNA-MALAT1 or pcDNA-MALAT1. The interplay among MALAT1, miR-20b-5p and STAT3 were evaluated through dual luciferase reporter gene assay and RNA pull-down after RB cells treated with siRNA/pcDNA-MALAT1 or/and miR-20b-5p mimic/inhibitor. The influence of their interaction on cells was evaluated by cell counting kit-8, EdU assay and flow cytometry. Finally, the involvement of MALAT1 in tumorigenesis was elucidated in vivo. RESULTS Both RB tissues and cells showed highly expressed MALAT1. When MALAT1 was downregulated, RB cell proliferation was hindered and apoptosis was accelerated. MALAT1 sponged miR-20b-5p and upregulated STAT3. Silencing MALAT1 or overexpressing miR-20b-5p inhibited proliferation and promoted apoptosis in RB cells. The tumor growth of nude mice treated with siRNA-MALAT1 was inhibited. CONCLUSION MALAT1 could increase proliferation and reduce apoptosis by sponging miR-20b-5p to upregulate STAT3 in RB cells. Therefore, MALAT1 might be a latent target in the RB treatment.

Long noncoding RNA LINC00205 enhances the malignant characteristics of retinoblastoma by acting as a molecular sponge of microRNA-665 and consequently increasing HMGB1 expression.

Abstract
Long intergenic non-protein-coding RNA 00205 (LINC00205) has been found to play crucial roles in hepatocellular carcinoma progression. In this study, we aimed to determine the expression pattern of LINC00205 in retinoblastoma (RB), to identify its functions in RB progression in detail, and to reveal the underlying mechanisms. Herein, we showed that LINC00205 is highly expressed in RB tissues and cell lines. The LINC00205 upregulation correlated with adverse clinicopathological parameters and shorter overall survival in patients with RB. LINC00205 depletion decreased the proliferative, migratory, and invasive abilities; promoted the apoptosis of RB cells in vitro; and impeded the tumor growth of RB cells in vivo. Mechanism investigation revealed that LINC00205 can act as a competing endogenous RNA by sponging microRNA-665 (miR-665) in RB cells, thereby upregulating miR-665's target: high-mobility group box 1 (HMGB1). Finally, rescue experiments confirmed that enhancing the miR-665-HMGB1 axis output attenuated the influence of the LINC00205 knockdown on RB cells. To sum up, the newly identified LINC00205-miR-665-HMGB1 pathway was systematically studied and may be validated as a potential target for RB diagnosis, prognosis, and therapy.

Int J Mol Med 2020; 45:1685-1696. [PMID: 32236565 PMCID: PMC7169960 DOI: 10.3892/ijmm.2020.4547] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2019] [Accepted: 01/30/2020] [Indexed: 12/11/2022] Open
Abstract
A long noncoding RNA called small nucleolar RNA host gene 14 (SNHG14) has been validated as a key regulator of cellular processes in multiple types of human cancer. However, to the best of our knowledge, the expression status and specific roles of SNHG14 in retinoblastoma (RB) have not been studied. The aims of the present study were to determine the expression status of SNHG14 in RB, assess the effects of SNHG14 on malignant characteristics of RB cells and investigate the mechanisms of action of SNHG14 in RB. SNHG14 expression levels in RB tissue samples and cell lines were measured by reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR). Cell proliferation, apoptosis, migration and invasion in vitro, and tumor growth in vivo were quantitated by the Cell Counting Kit‑8 assay, flow cytometry, migration and invasion assays, and mouse tumor xenograft experiments, respectively. The target microRNA (miRNA) of SNHG14 was predicted by bioinformatics analysis and was subsequently validated by a luciferase reporter assay, RNA immunoprecipitation (RIP) assay, RT‑qPCR, and western blot analysis. SNHG14 was identified to be significantly overexpressed in RB tissues and cell lines. SNHG14 overexpression was markedly associated with the intraocular international retinoblastoma classification stage, optic nerve invasion, and differentiation grade among patients with RB. The patients in the SNHG14 high‑expression group exhibited shorter overall survival compared with the SNHG14 low‑expression group. Functional analysis revealed that SNHG14 silencing inhibited cell proliferation, migration and invasion, and increased apoptosis in vitro, and decreased tumor growth in vivo. SNHG14 directly interacted with, and functioned as a competing endogenous RNA (ceRNA) of, miR‑124, consequently upregulating signal transducer and activator of transcription 3 (STAT3). miR‑124 inhibition and STAT3 expression recovery attenuated the effects of the SNHG14 silencing on RB cells. In conclusion, SNHG14 served as a ceRNA to upregulate STAT3 by sponging miR‑124. Therefore, targeting the SNHG14/miR‑124/STAT3 pathway may be an effective therapeutic strategy against RB.

Abstract
Background Retinoblastoma (RB) is the most common intraocular malignancy in children. Long non-coding RNA X-inactive specific transcript (lncRNA XIST) has been reported to be associated with RB, but research on the mechanism of XIST is not well studied. Methods Expressions of XIST, microRNA-140-5p (miR-140-5p), and sex-determining region Y-related high-mobility group box 4 (SOX4) were analyzed by qRT-PCR or Western blot. Relationships of XIST, SOX4, and miR-140-5p were evaluated by dual-luciferase reporter assay and Spearman’s analysis. Cell Counting Kit-8 (CCK-8) and Transwell assay were performed to assess the function of XIST on RB cell proliferation and invasion. Results In RB tissues, XIST and SOX4 expressions were obviously increased, but the miR-140-5p expression was markedly reduced. XIST expression was positively related to SOX4 expression while negatively correlated with miR-140-5p expression, and negative correlation was exhibited between miR-140-5p and SOX4 expression in RB tissues. XIST was confirmed to directly bind to miR-140-5p, and SOX4 was one target of miR-140-5p. XIST knockdown could impede RB cell proliferation and invasion, while miR-140-5p inhibition reversed the effects. In addition, XIST overexpression or miR-140-5p inhibition could abrogate the inhibition of SOX4 silencing on cell proliferation and invasion of RB cells. Conclusions XIST was obviously increased in RB tissues and cells, and XIST inhibition repressed the proliferation and invasion of RB cells by miR-140-5p/SOX4 axis, which may provide new understandings of the XIST molecular mechanism in RB.

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
Long noncoding RNA (lncRNA) small nucleolar RNA host gene 16 (SNHG16) has been linked to multiple cancers including breast, ovarian, bladder, and colorectal cancer. However, the role of SNHG16 in cervical cancer is unclear. Here, quantitative analysis of SNHG16 and PARP9 expression levels in cervical cancer tissues and cell lines indicated that both SNHG16 and PARP9 were highly expressed compared with controls. Using the dual-luciferase reporter gene assay, RNA immunoprecipitation, chromatin immunoprecipitation, we were able to determine that SNHG16 recruited SPI1 protein to promote transcription of PARP9 to upregulate its transcription in cervical cancer cells. After ectopic expression and knockdown experiments were conducted, it was observed that silencing SNHG16 inhibited PARP9 expression, proliferation, and invasion of cervical cancer cells, which was rescued by co-transfection of SNHG16 silencing and PARP9 overexpression. Moreover, in vivo experimental results showed that silencing SNHG16 reduced the expression of PARP9 and suppressed tumor growth. These data indicate that SNHG16 recruits SPI1 to upregulate PARP9, which promotes the tumorigenicity of cervical cancer cells. The regulation of their expression might provide a new direction for treating cervical cancer.

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
Purpose The oncogene of wild type neuroblastoma RAS viral oncogene homolog (NRAS) has been found to involve in the tumorigenesis of cancers. However, the role of NRAS in retinoblastoma (RB) progression remains largely unknown. Methods The expression levels of NRAS, miR-183-5p and small nucleolar RNA host gene 16 (SNHG16) were measured using quantitative real-time polymerase chain reaction assay or Western blot assay, respectively. Cell proliferation and apoptosis were analyzed with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay or flow cytometry, respectively. Transwell assay was used to determine cell migration and invasion abilities. The interaction between miR-183-5p and NRAS or SNHG16 was analyzed using bioinformatics analysis and dual-luciferase reporter assay. Results NRAS was elevated in RB tissues and cell lines, knockdown of NRAS could inhibit proliferation, migration and invasion but induced apoptosis in vitro and suppressed tumor growth in vivo. NRAS was confirmed to be a target of miR-183-5p and was negatively regulated by miR-183-5p in RB cells. Moreover, overexpressed NRAS reversed miR-183-5p mediated inhibition on RB cell progression. Besides that, SNHG16 directly interacted with miR-183-5p and reduced miR-183-5p expression in RB cells. The suppression of RB cell progression induced by SNHG16 silencing could be partially attenuated by the inhibition of miR-183-5p. Besides that, SNHG16 could regulate NRAS expression through competitively binding to miR-183-5p in RB cells. Conclusion NRAS functioned as an oncogene to contribute to RB progression by SNHG16/miR-183-5p/NRAS regulatory network, indicating a novel and promising therapeutic target for RB.

Abstract
Long non-coding (lnc) RNAs are non-coding RNAs longer than 200 nt. lncRNAs primarily interact with mRNA, DNA, protein, and miRNA and consequently regulate gene expression at the epigenetic, transcriptional, post-transcriptional, translational, and post-translational levels in a variety of ways. They play important roles in biological processes such as chromatin remodeling, transcriptional activation, transcriptional interference, RNA processing, and mRNA translation. lncRNAs have important functions in plant growth and development; biotic and abiotic stress responses; and in regulation of cell differentiation, the cell cycle, and the occurrence of many diseases in humans and animals. In this review, we summarize the functions and mechanisms of lncRNAs in plants, humans, and animals at different regulatory levels.
