Abstract
Long noncoding RNAs (lncRNAs) represent an important group of endogenous RNAs with limit protein-encoding capability, with a length of more than 200 nucleotides. Emerging evidence have demonstrated that lncRNAs are greatly involved in multiple cancers by playing critical roles in tumor initiation and progression. Long intergenic non-protein coding RNA 460 (LINC00460), a novel cancer-related lncRNA, exhibits abnormal expression and oncogenic function in multiple cancers, and positively correlates with poor clinical characteristics of cancer patients. LINC00460 has also been shown to be a promising biomarker for diagnosis as well as prognostic evaluation in cancer patients. In this review, we briefly summarized recent knowledge on the expression, functional roles, molecular mechanisms, and diagnostic and prognostic values of LINC00460 in human malignancies.

Abstract
Long non-coding RNAs (LncRNAs), which are more than 200 nucleotides in length and with limited protein-coding potential, play vital roles in the pathogenesis, tumorigenesis, and angiogenesis of cancers. Aberrant expression of lncRNAs has been detected in various carcinomas and may be correlated with oncogenesis by affecting related genes expression. Recently, an increasing number of studies have reported on long intergenic non-protein coding RNA 460 (LINC00460) in human tumor fields. LINC00460 is upregulated in diverse cancer tissues and cells. The upregulated expression level of LINC00460 is correlated with larger tumor size, tumor node metastasis (TNM) stage, lymph node metastasis, and shorter overall survival. The regulatory mechanism of LINC00460 was complex and diverse. LINC00460 could act as a competitive endogenous RNA (ceRNA), directly bind with proteins or regulate multiple pathways, which affected tumor progression. Moreover, LINC00460 was also identified to increase drug resistance, and therefore, weaken the effectiveness of tumor treatment. It has become increasingly important to investigate the roles of LINC00460 in various cancers by different mechanisms. Therefore, a more comprehensive understanding of LINC00460 is crucial to expound on the cellular function and molecular mechanism of human cancers. In this review, we refer to studies concerning LINC00460 and provide the basis for the evaluation of LINC00460 as a predicted biomarker or potential therapeutic target in malignancies, and also provide ideas for the future research of lncRNAs similar to LINC00460.

Abstract
Glioma is the most common primary tumour in the central nervous system in adults, and at present, there is no effective treatment to cure this malignancy. Long noncoding RNAs (lncRNAs) are closely related to tumour progression and have attracted increasing attention in tumour research. However, the role of lncRNA FGF14-AS2 in glioma tumorigenesis has not been determined. In the present study, we found that FGF14-AS2 expression was significantly elevated in glioma tissues and was associated with poor survival in glioma patients. Silencing FGF14-AS2 inhibited the proliferation, migration and invasion ability of glioma cells. In vivo assay showed that silencing FGF14-AS2 led to inhibition of tumour growth. In addition, FGF14-AS2 was observed to promote glioma progression via the miR-320a/E2F1 axis. Moreover, E2F1 could bind to the promoter region of FGF14-AS2, thereby enhancing FGF14-AS2 expression. In conclusion, FGF14-AS2 could accelerate tumorigenesis of glioma by forming a feedback loop with the miR-320a/E2F1 axis which suggested that FGF14-AS2 could serve as a therapeutic target for glioma.

Abstract
Long intergenic non-coding RNAs (lincRNAs) establish a group of long non-coding RNAs (lncRNAs) that have no overlap with protein-coding genes. These transcripts have been found to affect chromatin configurations, arrange high-order nuclear structures, function as scaffolds for proteins and RNAs and serve as molecular decoys. LINC00460 is a member of this group of lincRNAs that participate in the pathoetiology of cancers. This lincRNA has been found to serve as a sponge for a number of tumor suppressor miRNAs, including miR-539, miR-1224-5p, miR-612, miR-342-3p, miR-485-5p and miR-149-5p, and increase expression of oncogenic targets of these miRNAs. Moreover, through targeting miRNAs that regulate sensitivity to chemotherapeutic agents, it can affect response of cancer cells to these agents. In the current manuscript, we tended to describe the role of LINC00460 in this process through summarizing the results of in vitro, in vivo and human studies.

Abstract
The long intergic non-protein coding RNA 460 (LINC00460) is abnormally highly expressed in gastrointestinal tumors and plays an important role in promoting tumor formation and development. LINC00460 is mainly distributed in cytoplasm and has many abnormal gene variants of single nucleotide polymorphism in tumors. LINC00460 can promote the proliferation, metastasis, angiogenesis, radiotherapy and chemotherapy resistance, inhibit the apoptosis of tumor cells, and further promote the malignant progression of tumors via involving in chromatin state maintenance, methylation modification, endogenous competition and transcriptional regulation. It may serve as a valuable tumor marker and therapeutic target.

Abstract
MicroRNAs are a set of highly conserved non-coding RNAs that control gene expression at the post-transcriptional/translational levels by binding to the 3′-UTR of diverse target genes. Increasing evidence indicates that miRNAs not only play a vital role in many biological processes, but they are also frequently deregulated in pathological conditions, including cancer. The miR-320 family is one of many tumor suppressor families and is composed of five members, which has been demonstrated to be related to the repression of epithelial-mesenchymal transition (EMT) inhibition, cell proliferation, and apoptosis. Moreover, this family has been shown to regulate drug resistance, and act as a potential biomarker for the diagnosis, prognosis, and prediction of cancer. In this review, we summarized recent research with reference to the tumor suppressor function of miR-320 and the regulation mechanisms of miR-320 expression. The collected evidence shown here supports that miR-320 may act as a novel biomarker for cancer prognosis and therapeutic response to cancer treatment.

Mol Med Rep 2021; 23:435.

Abstract
Long non-coding RNA 00460 (LINC00460) has been reported to be involved in the tumorigenesis of various cancer types. However, the function of LINC00460 in acute myeloid leukemia (AML) remains elusive. Therefore, the present study aimed to investigate the role of LINC00460 in AML. The expression of LINC00460 in the serum of 80 diagnosed patients with AML and 67 healthy controls was measured via reverse transcription-quantitative polymerase chain reaction, and the results were compared with clinical features and patient outcomes. The expression of LINC00460 in 45 patients with cytogenetically normal-AML (CN-AML) was also assayed. Receiver operating characteristic (ROC) curves were generated to evaluate the sensitivity and specificity of serum LINC00460. In addition, the effects of LINC00460 on the viability, cell cycle distribution and apoptosis of AML cells were investigated. Bioinformatics tools were used to identify the possible mechanisms of how LINC00460 affects AML cells. It was found that the expression of LINC00460 was significantly upregulated in the serum of patients with AML and those with CN-AML. Higher expression of serum LINC00460 was positively associated with French-American-British classification and cytogenetics. Furthermore, ROC curve analyses demonstrated that serum LINC00460 could differentiate patients with AML from healthy individuals with an area under the curve of 0.8488 (95% CI, 0.7697–0.9279). The serum LINC00460 expression was also significantly decreased when the patients achieved complete remission. Kaplan-Meier analysis indicated that patients with high serum LINC00460 expression had a shorter overall survival time compared with the low serum LINC00460 expression group. Knockdown of LINC00460 inhibited viability, while inducing cell cycle arrest and apoptosis in AML cells. LINC00460 was also a decoy of microRNA (miR)-320b, which can further inhibit the expression of PBX homeobox 3 (PBX3). Collectively, the results suggested that LINC00460 may be applied as a potential diagnostic and prognostic biomarker for patients with AML. It was identified that LINC00460 may exert its effects, at least partly, via the miR-320b/PBX3 axis in AML.

Abstract
Breast cancer (BRCA) is a serious public health problem, as it is the most frequent malignant tumor in women worldwide. BRCA is a molecularly heterogeneous disease, particularly at gene expression (mRNAs) level. Recent evidence shows that coding RNAs represent only 34% of the total transcriptome in a human cell. The rest of the 66% of RNAs are non−coding, so we might be missing relevant biological, clinical or regulatory information. In this report, we identified two novel tumor types from TCGA with LINC00460 deregulation. We used survival analysis to demonstrate that LINC00460 expression is a marker for poor overall (OS), relapse-free (RFS) and distant metastasis-free survival (DMFS) in basal-like BRCA patients. LINC00460 expression is a potential marker for aggressive phenotypes in distinct tumors, including HPV-negative HNSC, stage IV KIRC, locally advanced lung cancer and basal-like BRCA. We show that the LINC00460 prognostic expression effect is tissue-specific, since its upregulation can predict poor OS in some tumors, but also predicts an improved clinical course in BRCA patients. We found that the LINC00460 expression is significantly enriched in the Basal-like 2 (BL2) TNBC subtype and potentially regulates the WNT differentiation pathway. LINC00460 can also modulate a plethora of immunogenic related genes in BRCA, such as SFRP5, FOSL1, IFNK, CSF2, DUSP7 and IL1A and interacts with miR-103-a-1, in-silico, which, in turn, can no longer target WNT7A. Finally, LINC00460:WNT7A ratio constitutes a composite marker for decreased OS and DMFS in Basal-like BRCA, and can predict anthracycline therapy response in ER-BRCA patients. This evidence confirms that LINC00460 is a master regulator in BRCA molecular circuits and influences clinical outcome.

Onco Targets Ther 2021; 14:2279-2291. [PMID: 33833526 PMCID: PMC8019668 DOI: 10.2147/ott.s282947] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Accepted: 01/26/2021] [Indexed: 12/25/2022] Open
Abstract
Purpose Long non-coding RNAs (lncRNAs) play critical roles in cancer onset and development, including head and neck squamous cell carcinoma (HNSCC). This study aimed to investigate the biological role of LINC00460 and the mechanisms underlying epithelial-mesenchymal transition (EMT) in HNSCC. Methods Aberrantly LINC00460 expression in HNSCC and overall survival outcomes were constructed using the TCGA database. Quantitative real-time polymerase chain reaction (RT-qPCR) was applied to examine the LINC00460 expression level in HNSCC cell lines. The role of LINC00460 knockdown on HNSCC cell growth, migration, invasion, and EMT was investigated in vitro using cell counting kit-8 (CCK-8), colony formation, transwell assay, and Western blot assay. Besides, bioinformatics prediction, dual-luciferase reporter assay, and RNA immunoprecipitation (RIP) were performed to reveal the interaction among LINC00460 and its target genes. The function of the LINC00460/miR-320a/BGN axis in HNSCC cells was clarified by rescue assays. Furthermore, the in vivo effects of LINC00460 on tumor growth were investigated using mice xenograft models. Results In this study, LINC00460 was upregulated in HNSCC tissues and cells and was associated with poor clinical prognosis. Further functional analysis showed that LINC00460 knockdown decreased HNSCC cell proliferation, migration, invasion, as well as EMT in vitro. Mechanistic investigation indicated that LINC00460 sponged miR-320a to upregulate Biglycan (BGN) expression, thereby facilitating HNSCC progression and induced EMT. Moreover, knockdown of LINC00460 significantly suppressed the progression of HNSCC cells in vivo. Conclusion Taken together, LINC00460 mediates miR-320a/BGN signaling axis to promote cell proliferation, migration, invasion, and induce the EMT process in HNSCC cells. Our findings elucidated a novel mechanism underlying the progression of HNSCC. LINC00460 could serve as a potential therapeutic target for the treatment of HNSCC.

Khandelwal A, Sharma U, Barwal TS, Seam RK, Gupta M, Rana MK, Vasquez KM, Jain A. Circulating miR-320a Acts as a Tumor Suppressor and Prognostic Factor in Non-small Cell Lung Cancer. Front Oncol 2021; 11:645475. [PMID: 33833996 PMCID: PMC8021852 DOI: 10.3389/fonc.2021.645475] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Accepted: 02/22/2021] [Indexed: 12/24/2022] Open
Abstract
Dysregulated expression profiles of microRNAs (miRNAs) have been observed in several types of cancer, including non-small cell lung cancer (NSCLC); however, the diagnostic and prognostic potential of circulating miRNAs in NSCLC remains largely undefined. Here we found that circulating miR-320a was significantly down-regulated (~5.87-fold; p < 0.0001) in NSCLC patients (n = 80) compared to matched control plasma samples from healthy subjects (n = 80). Kaplan-Meier survival analysis revealed that NSCLC patients with lower levels of circulating miR-320a had overall poorer prognosis and survival rates compared to patients with higher levels (p < 0.0001). Moreover, the diagnostic and prognostic potential of miR-320a correlated with clinicopathological characteristics such as tumor size, tumor node metastasis (TNM) stage, and lymph node metastasis. Functionally, depletion of miR-320a in human A549 lung adenocarcinoma cells induced their metastatic potential and reduced apoptosis, which was reversed by exogenous re-expression of miR-320a mimics, indicating that miR-320a has a tumor-suppressive role in NSCLC. These results were further supported by high levels of epithelial-mesenchymal transition (EMT) marker proteins (e.g., Beta-catenin, MMP9, and E-cadherin) in lung cancer cells and tissues via immunoblot and immunohistochemistry experiments. Moreover, through bioinformatics and dual-luciferase reporter assays, we demonstrated that AKT3 was a direct target of miR-320a. In addition, AKT3-associated PI3K/AKT/mTOR protein-signaling pathways were elevated with down-regulated miR-320a levels in NSCLC. These composite data indicate that circulating miR-320a may function as a tumor-suppressor miRNA with potential as a prognostic marker for NSCLC patients.

Abstract
PURPOSE It is generally accepted that long noncoding RNAs (lncRNAs) function as vital regulators of tumor development and progression. Long intergenic non-coding RNA 1410 (LINC01410) is a newly discovered lncRNA, and its role in osteosarcoma (OS) is yet to be determined. MATERIALS AND METHODS The expression of LINC01410, microRNA-122-5p (miR-122-5p), and N-myc downstream-regulated gene 3 (NDRG3) in OS tissues was determined using reverse transcription-quantitative PCR. Interactions between LINC01410, miR-122-5p, and NDRG3 were predicted and verified using bioinformatics tools and luciferase assays. Cell proliferation, migration, and invasion were detected using cell counting Kit-8 and Transwell assays. RESULTS LINC01410 was overexpressed in OS tissues. Furthermore, it was confirmed that LINC01410 facilitated OS cell proliferation and migration. Our studies also showed that LINC01410 binds to miR-122-5p, and miR-122-5p binds to NDRG3. Finally, we observed that LINC01410 knockdown inhibited the proliferation, invasion, and migration of OS cells. Knockdown of LINC01410 resulted in the upregulation of miR-122-5p and downregulation of NDRG3. CONCLUSION Our results demonstrated that the LINC01410/miR-122-5p/NDRG3 axis is involved in the progression of OS.

[PMID: 32851059 PMCID: PMC7441444 DOI: 10.1155/2020/1971284] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 06/02/2020] [Accepted: 06/24/2020] [Indexed: 11/24/2022]
Abstract
Introduction Glioblastoma is the most malignant grade of glioma, and it is also the most common primary tumor in the brain. Immunotherapy is a kind of precise tumor treatment. However, there are limited studies about immune-related lncRNA. This study is aimed at analyzing immune-related lncRNAs in glioblastoma and screening out prognostic factors, providing new potential targets for glioblastoma immunology research. Material and Methods. Gene expression data and clinical data of IDH wild-type with MGMT promoter unmethylated glioblastoma were acquired from the TCGA and CGGA databases. Immune-related lncRNAs were identified with the help of data from the InnateDB database. Immune prognostic factors were recognized by Cox regression analysis. GSEA analysis pursued their potential functions. Results We found 318 immune-related lncRNAs. Among them, there were 137 immune-related lncRNAs that were upregulated and 181 that were downregulated. 15 prognostic lncRNAs were identified by Cox regression, and a total of 6 molecules were included in the following risk scoring model. GSEA showed that these lncRNAs participated in functions such as protein digestion and absorption and the PPAR signaling pathway. Conclusion There are limited studies about immune regulation mechanisms of lncRNA in IDH wild-type with MGMT promoter unmethylated glioblastoma. The identified immune-related lncRNAs in glioblastoma might contribute new targets and research directions for immunological molecular studies of glioblastoma.

Long non-coding RNA LINC00460 predicts poor survival and promotes cell viability in pancreatic cancer. Oncol Lett 2020; 20:1369-1375.

Abstract
Emerging evidence has demonstrated that long non-coding RNAs (lncRNAs) possess great potential as vital biomarkers and powerful therapeutic targets in various diseases. In the present study, differentially expressed transcripts in pancreatic cancer (PC) were identified, and a competing endogenous RNA (ceRNA) network was constructed using The Cancer Genome Atlas database. An independent cohort consisting of 59 patients with PC was used to validate the clinical value of the identified lncRNA. Cell viability and colony formation assays were used to evaluate the biological functions of the lncRNA in PC cells. The present bioinformatic analysis revealed that LINC00460 was upregulated in PC samples with a prognostic significance. In the ceRNA network, it potentially targeted the microRNA-503/cyclin D1 axis. The results of real-time quantitative PCR confirmed that LINC00460 was significantly upregulated in cancer tissues and was associated with poor survival of patients with PC. The expression levels of LINC00460 were significantly associated with tumor size, but not with age, sex, differentiation, lymph node metastasis, vascular invasion and tumor stage. Through univariate and multivariate analysis, LINC00460 was characterized as an independent prognostic biomarker for PC. Further in vitro experiments demonstrated that suppressing LINC00460 using small interfering RNA inhibited viability and colony formation of PC cells. In summary, LINC00460 may be an independent prognostic biomarker for PC and may serve as an oncogenic lncRNA that promotes PC cell growth. Further in-depth exploration is required to reveal the specific biological mechanism of LINC00460 in PC cells.

Abstract
Background Long noncoding RNAs (lncRNAs) are recognized as key effectors in tumor, including glioma. LINC01494 is an uncharacterized novel lncRNA. In this research, we aimed to investigate the function of LINC01494 in glioma. Methods Gene relative expression was analyzed by qRT-PCR method. CCK8, colony formation and Transwell assay was used to determine cell proliferation, migration and invasion. Bioinformatics analyses were used to predict the target of LINC01494 and miR-122-5p. Luciferase reporter assay was utilized to validate the interactions between LINC01494 and miR-122-5p or CCNG1 and miR-122-5p. Results LINC01494 was identified as a significantly upregulated lncRNA in glioma through bioinformatics analysis. Furthermore, LINC01494 upregulation indicated poor prognosis. Meanwhile, in vitro investigation indicated that silencing LINC01494 with siRNAs obviously inhibited the proliferation, cell cycle, migration and invasion of glioma cells. Besides, it is found that LINC01494 expression was negatively correlated with miR-122-5p. We demonstrated that LINC01494 inhibited miR-122-5p to upregulate CCNG1 expression through direct interaction. Rescue assay further demonstrated that LINC01494/miR-122-5p/CCNG1 signaling cascade plays a critical role in regulating glioma cell proliferation, migration and invasion. Conclusion Taken together, our findings demonstrated the essential function and molecular mechanism of LINC01494 in glioma progression.

Abstract
Objective Long noncoding RNA 00460 (LINC00460) has been reported to contribute to tumorigenesis in multiple types of human malignancies. However, the biological role and the underlying molecular mechanism of LINC00460 in glioma remain unclear. The aim of this study was to investigate the clinical value, the biological function, and the potential mechanism of LINC00460 in glioma. Methods The expression level of LINC00460 in glioma tissues and cell lines was examined by quantitative real‐time polymerase chain reaction (qRT‐PCR). Cell Counting Kit‐8, flow cemetery, wound healing, and transwell invasion assays were used to explore the effect of LINC00460 on glioma cell proliferation, apoptosis, migration, and invasion. qRT‐PCR and reporter assays were used to further verify the regulatory mechanism of LINC00460 in glioma progression. Results LINC00460 expression was upregulated in glioma tissues and cell lines compared with non–tumor brain samples and astrocyte cell line (NHA), respectively. Moreover, increased LINC00460 expression was closely associated with glioma tumor grade. Loss‐of‐function assays revealed that knockdown of LINC00460 significantly inhibited glioma cell proliferation, induced cell apoptosis, and suppressed migration and invasion. The mechanistic assays disclosed that LINC00460 binded to miR‐320a in a sequence‐specific manner and regulated its expression. Moreover, miR‐320 inhibition partially attenuated LINC00460 knockdown‐mediated suppressive effects on glioma cell proliferation, migration, and invasion. Conclusion These findings suggested that LINC00460 might function as an oncogenic lncRNA in glioma development and could be explored as a potential therapeutic target for glioma.
