[PMID: 38601076 PMCID: PMC11004358 DOI: 10.3389/fgene.2024.1362420] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Accepted: 03/15/2024] [Indexed: 04/12/2024] Open
Abstract
Objective Recent studies have revealed increasing evidence that the long non-coding RNA bladder cancer associated transcript 1 (LncRNA BLACAT1) plays an essential role in the emergence of different malignancies. This meta-analysis aimed to evaluate the prognostic significance of LncRNA BLACAT1 in various cancers. Methods Six electronic databases (PubMed, Embase, Medline, Web of Science, China National Knowledge Infrastructure (CNKI), and the Chinese WanFang database) were comprehensively searched for relevant studies. The analysis of overall survival (OS) and clinicopathological characteristics was conducted. Results Nineteen studies with 1,559 patients were eventually eligible to be included in this meta-analysis. High expression level of LncRNA BLACAT1 was identified to be linked with shorter OS (HR: 2.02, 95% CI: 1.66-2.46, p < 0.001) and PFS (HR: 2.424, 95% CI: 1.827-3.020, p < 0.001) in cancer patients as opposed to low expression levels. Subgroup analysis showed that analysis model (multivariate or univariate), cut-off value (mean or median), sample size (more or fewer than 100), and cancer type had little effect on OS in multiple tumors. Moreover, high LncRNA BLACAT1 expression was associated with positive lymph node metastasis (HR: 2.29, 95% CI: 1.66-3.16, p < 0.00001), advanced clinical stage (HR: 2.29, 95% CI: 1.65-3.19, p < 0.00001) and worse differentiation status (HR: 0.58, 95% CI: 0.37-0.92, p = 0.02), compared to low LncRNA BLACAT1 expression. Conclusion The findings highlight that high LncRNA BLACAT1 expression might be detrimental and induce a worse prognosis for cancer patients.

Abstract
Ribonucleic acid (RNA) molecules are indispensable for cellular homeostasis in healthy and malignant cells. However, the functions of RNA extend well beyond that of a protein-coding template. Rather, both coding and non-coding RNA molecules function through critical interactions with a plethora of cellular molecules, including other RNAs, DNA, and proteins. Deconvoluting this RNA interactome, including the interacting partners, the nature of the interaction, and dynamic changes of these interactions in malignancies has yielded fundamental advances in knowledge and are emerging as a novel therapeutic strategy in cancer. Here, we present an RNA-centric review of recent advances in the field of RNA-RNA, RNA-protein, and RNA-DNA interactomic network analysis and their impact across the Hallmarks of Cancer. This article is categorized under: RNA in Disease and Development > RNA in Disease RNA Interactions with Proteins and Other Molecules > RNA-Protein Complexes.

J Gene Med 2023:e3485. [PMID: 36811210 DOI: 10.1002/jgm.3485] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 01/02/2023] [Accepted: 02/16/2023] [Indexed: 02/24/2023] Open
Abstract
BACKGROUND Long non-coding RNAs have been established to promote or inhibit the oncogenic and tumorigenic potential of various cancers, acting as competing endogenous RNAs (ceRNAs) for specific microRNAs. The primary objective of the study was to investigate the underlying mechanism by which the LINC02027/miR-625-3p/PDLIM5 axis affects proliferation, migration and invasion in hepatocellular carcinoma (HCC). METHODS The differentially expressed gene was selected based on gene sequencing and bioinformation database analysis of HCC and adjacent non-tumor tissues. The expression of LINC02027 in HCC tissues and cells and its regulatory effect on the development of HCC were detected by colony formation, cell counting kit-8 assays, wound healing assays, Transwell assays and subcutaneous tumorigenesis assays in nude mice. According to the results of database prediction, quantitative real-time polymerase chain reaction and dual-luciferase reporter assay, the downstream microRNA and target gene were searched. Finally, HCC cells were transfected with lentivirus and used for cell function assays in vitro and in vivo. RESULTS Downregulation of LINC02027 was detected in HCC tissues and cell lines and was associated with poor prognosis. The overexpression of LINC02027 suppressed the proliferation, migration and invasion of HCC cells. Mechanistically, LINC02027 inhibited epithelial-to-mesenchymal transition. As a ceRNA, LINC02027 inhibited the malignant ability of HCC by competitively binding to miR-625-3p to regulate the expression of PDLIM5. CONCLUSIONS The LINC02027/miR-625-3p/PDLIM5 axis inhibits the development of HCC.

[PMID: 34819106 PMCID: PMC8611860 DOI: 10.1186/s12938-021-00952-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Accepted: 11/06/2021] [Indexed: 12/18/2022] Open
Abstract
Background Lung adenocarcinoma (LUAD) is the most common subtype of nonsmall-cell lung cancer (NSCLC) and has a high incidence rate and mortality. The survival of LUAD patients has increased with the development of targeted therapeutics, but the prognosis of these patients is still poor. Long noncoding RNAs (lncRNAs) play an important role in the occurrence and development of LUAD. The purpose of this study was to identify novel abnormally regulated lncRNA–microRNA (miRNA)–messenger RNA (mRNA) competing endogenous RNA (ceRNA) networks that may suggest new therapeutic targets for LUAD or relate to LUAD prognosis. Methods We used the SBC human ceRNA array V1.0 to screen for differentially expressed (DE) lncRNAs and mRNAs in four paired LUAD samples. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed to annotate the DE lncRNAs and mRNAs. R bioinformatics packages, The Cancer Genome Atlas (TCGA) LUAD database, and Kaplan–Meier (KM) survival analysis tools were used to validate the microarray data and construct the lncRNA–miRNA–mRNA ceRNA regulatory network. Then, quantitative real-time PCR (qRT-PCR) was used to validate the DE lncRNAs in 7 LUAD cell lines. Results A total of 2819 DE lncRNAs and 2396 DE mRNAs (P < 0.05 and fold change ≥ 2 or ≤ 0.5) were identified in four paired LUAD tissue samples. In total, 255 of the DE lncRNAs were also identified in TCGA. The GO and KEGG analysis results suggested that the DE genes were most enriched in angiogenesis and cell proliferation, and were closely related to human cancers. Moreover, the differential expression of ENST00000609697, ENST00000602992, and NR_024321 was consistent with the microarray data, as determined by qRT-PCR validation in 7 LUAD cell lines; however, only ENST00000609697 was associated with the overall survival of LUAD patients (log-rank P = 0.029). Finally, through analysis of ENST00000609697 target genes, we identified the ENST00000609697–hsa-miR-6791-5p–RASL12 ceRNA network, which may play a tumor-suppressive role in LUAD. Conclusion ENST00000609697 was abnormally expressed in LUAD. Furthermore, downregulation of ENST00000609697 and its target gene RASL12 was associated with poor prognosis in LUAD. The ENST00000609697–hsa-miR-6791-5p–RASL12 axis may play a tumor-suppressive role. These results suggest new potential prognostic and therapeutic biomarkers for LUAD.

Abstract
Increasing evidence has indicated that microRNA dysregulation is closely related to the occurrence and development of cancers. Herein, we investigated the relationship between miR-144-3p and CEP55 expression. We then evaluated the association between miR-144-3p and CEP55 expression and proliferation, invasion and apoptosis of non-small cell lung cancer (NSCLC) cells. Real-time quantitative PCR results revealed that CEP55 was over-expressed whereas miR-144-3p was under-expressed in NSCLC tissues. CCK-8 assay, wound healing assay, and flow cytometry further revealed that overexpression of miR-144-3p significantly inhibited proliferation and migration, but promoted apoptosis of A549 cells. Conversely, inhibition of miR-144-3p promoted proliferation and migration but suppressed apoptosis of H460 cells. Dual-luciferase reporter assay revealed that miR-144-3p modulated malignant properties of cancer cells by targeting CEP55. Overexpression of CEP55 partially blocked the inhibitory effect of miR-144-3p on proliferation and migration of A549 cells and induced apoptosis of A549 cells. CEP55 knockdown modulated the increase in proliferation and migration and the decrease in apoptosis of H460 cells following miR-144-3p inhibition. These findings demonstrated that miR-144-3p suppresses NSCLC development by inhibiting CEP55 expression.

Abstract
Purpose Bladder cancer is a common malignant tumor of the urinary system, with the fourth-highest incidence of male malignant tumors in Europe and the United States. So far, the mechanism of bladder cancer progression and metastasis has not been clarified. The aim of our study was to validate the way of long noncoding RNA (lncRNA) KCNMB2-AS1 on the metabolism and growth of bladder cancer cells by miR-3194-3p/SMAD5. Patients and Methods The Gene Expression was analyzed by qRT-PCR in bladder cancer tissues and cell lines, with the highly expressed KCNMB2-AS1 screened out. Cell proliferation was detected by Edu staining and clone formation assay, cell migration, and invasion by wound healing and transwell assays. Cell stemness was determined by assessing sphere-forming ability and stemness marker. Correlation between miRNA and lncRNA/gene was verified by dual‐luciferase assay and RIP, and the effect of KCNMB2-AS1 on bladder cancer growth by nude mice tumor formation experiment. Results Here, we revealed the increased level of KCNMB2-AS1 in bladder cancer for the first time. Knockdown of KCNMB2-AS1 in vitro prevented the ability of proliferation, metastasis, and stemness of cancer cells. In vivo, the silencing of KCNMB2-AS1 also prevented tumor growth in vivo. Next, we revealed that KCNMB2-AS1 could interact with miR-3194-3p and uncovered that SAMD5 was a downstream target of miR-3194-3p. Conclusion In conclusion, KCNMB2-AS1 mediated the bladder cancer cells progress by regulating the miR-3194-3p/SAMD5 signal pathway, which would provide a new target for bladder cancer research.

Abstract
According to previous studies, linc-UBC1 is abnormally expressed in various human tumours. Nonetheless, the clinical significance and mechanism of linc-UBC1 in cancer remains unclear. In our present analysis, we wanted to explore the specific role of linc-UBC1 in malignant tumours by integrating all of the relevant literature and subsequently elucidating the relationship between linc-UBC1 expression level and clinical characteristics of cancers. An elaborate database search of PubMed, Embase, Wanfang Data, Web of Science, Ovid, Medline, Cochrane Library and PMC was carried out up to 8 August 2019. We further applied the pooled odds ratio (OR) and hazard ratio (HR) to evaluate OS. After filtering by strict criteria, 11 studies containing 1017 cases were included in this analysis. Our results implied that high expression of linc-UBC1 was obviously related to poor OS in cancer (HR =1.735, 95% 1.348-2.235, p < .001 random effects model). Analogously, the data revealed that high expression of linc-UBC1 was highly correlated with lymph node metastasis (OR = 2.912, 95% CI: 2.056-4.125, p < .001 fix effects model) and high tumour stage (OR = 2.678, 95% CI: 1.859-3.857, p < .001 fix effects model). In summary, linc-UBC1 overexpression is associated with poor OS and advanced tumour stage and could be used as a novel prognostic biomarker in various cancers.

Abstract
BACKGROUND Colorectal cancer (CRC) is a common severe disease around the world. The merging papers reported that long noncoding RNAs (lncRNAs) took part in the diversified pathological processes of CRC. This study aimed to uncover the role and the potential mechanism of lncRNA bladder cancer-associated transcript 1 (BLACAT1) in CRC progression. METHODS LncRNA BLACAT1, micro-519d-3p (miR-519d-3p), and cAMP-responsive element binding protein 1 (CREB1) levels were detected by quantitative real-time polymerase chain reaction (qRT-PCR) in CRC tissues and cells. The bio-functional effects were examined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT), flow cytometry assay, and transwell assay. The susceptibility testing was determined by oxaliplatin (OXA) administration. The potential binding sites between miR-519d-3p and BLACAT1 or CREB1 were predicted by online software starBase and confirmed by dual-luciferase reporter analysis. The relative proteins expression in CRC cells was determined by Western blot analysis. Xenograft tumor model was used to evaluate biological function of BLACAT1 in vivo. RESULTS The expression of BLACAT1 was promoted in CRC tissues and cells, and correlated to the TNM (tumor, node, metastasis) stage, distant metastasis, and overall survival rate. Silencing of BLACAT1 limited the proliferation, migration, and invasion, facilitated the apoptosis, and re-sensitized OXA-resistance in CRC cells. MiR-519d-3p was a target of BLACAT1. Furthermore, miR-519d-3p deletion reversed the positive effects of BLACAT1 deletion on CRC cells. Moreover, our data showed that miR-519d-3p directly targeted CREB1 and BLACAT1 sponged miR-519d-3p to regulate CREB1 expression. Besides, CREB1 disrupted the bio-functional results above from BLACAT1 suppression. Additionally, BLACAT1 knockdown promoted CRC cells sensitivity to OXA in vivo. CONCLUSION BLACAT1 mediated the progression of CRC and OXA-resistance by miR-519d-3p/CREB1 axis.

Abstract
Long intergenic noncoding RNA smad7 (Linc-smad7) has been recently identified as a new long non-coding RNA (lncRNA). However, the role of Linc-smad7 in the tumourigenesis of human cancers remains unknown. This study uncovered that Linc-smad7 was increased in HCC samples and HCC cell lines using RT-qPCR assays. Furthermore, the overexpression of Linc-smad7 indicated poor clinicopathological features and outcomes for HCC patients. In addition, Linc-smad7 promoted HCC cells proliferation, migration, invasion and EMT, as determined by MTT, colony formation, Transwell assays and western blot analysis. Functionally, it was demonstrated that Linc-smad7 could bind with microRNA-125b (miR-125b), and the restoration of miR-125b rescued the promoting effects of Linc-smad7 on HCC cells. Finally, it was observed that sirtuin 6 (SIRT6) was positively regulated by Linc-smad7 in HCC as the direct target of miR-125b, and decreased SIRT6 reversed the effects of Linc-smad7 on promoting HCC. In conclusion, the current study first identified Linc-smad7 is increased in HCC, facilitating HCC cells proliferation, migration, invasion and EMT via regulating the miR-125b/SIRT6 axis.

Abstract
Lung adenocarcinoma (LUAD) is the most common histological subtype of lung cancer. The abnormal expression of long noncoding RNAs (lncRNAs) can facilitate or suppress the development of malignant tumors. lncRNA actin alpha 2, smooth muscle antisense RNA 1 (ACTA2-AS1) has been reported to function as a tumor suppressor in liver cancer, nevertheless, its influences on LUAD remain to be investigated. In this paper, ACTA2-AS1 was identified as a downregulated lncRNA in LUAD samples and cells. Functionally, ACTA2-AS1 overexpression restrained cell proliferation but accelerated cell apoptosis in LUAD. In addition, we determined the suppressive effect of ACTA2-AS1 on LUAD cell invasion, migration, and epithelial-mesenchymal transition progress. Mechanistically, ACTA2-AS1 exert functions as a competing endogenous RNA through serving as a sponge for microRNA-378a-3p (miR-378a-3p) and microRNA-4428 (miR-4428) to elevate SRY-related high-mobility group box 7 (SOX7) expression. Importantly, SOX7 silencing could recover the ACTA2-AS1-mediated cell functions. To summarize, ACTA2-AS1 suppresses the malignant processes of LUAD cells through sequestering miR-378a-3p and miR-4428 to augment SOX7 expression.

Abstract
Long non-coding RNAs (lncRNAs) play indispensable roles in mediating regulation of epigenetics, and their dysregulation is strongly associated with the initiation and progression of human cancers. Recently, lncRNA bladder cancer-associated transcript 1 (BLACAT1) has been observed to exert oncogenic effects on cancers, including glioma, breast cancer, lung cancer, hepatocellular carcinoma, gastric cancer, colorectal cancer, ovarian cancer, cervical cancer and osteosarcoma. Additional mechanical analyses have uncovered that lncRNA BLACAT1 is positively correlated with tumor stage, lymph node metastasis and distant metastasis of primary tumors via involvement with various cellular activities, thus leading to poor overall survival and progression-free survival (PFS). In this review, we generalize the oncogenic roles of BLACAT1 in multiple human cancers through correlation with clinical implications and cellular activities. Moreover, we forecast its potential clinical application as a novel biomarker and a promising therapeutic target for cancers.

Abstract
Long non-coding RNAs (lncRNAs) are a cluster of RNAs with more than 200 nucleotides in length, which lack protein-coding capacity. They are important regulators of numerous cellular processes, including gene transcription, translation, and posttranslational modification, especially in tumor initiation and progression. Aberrant expression of lncRNA bladder cancer-associated transcript 1 (BLACAT1) has been reported in various human cancers and was usually associated with unfavorable prognosis. Previous studies have revealed that dysregulation of BLACAT1 could promote the proliferation and metastasis of cancer cells. In this review, we summarize the present understanding of the functions and underlying mechanisms of BLACAT1 in the occurrence and development of various human cancers and discuss the roles of this lncRNA in cancers, including its promising application as a prognostic biomarker or a novel therapeutic target for malignancies.

Abstract
Purpose LINC00680 was reported to be involved in various cancers through multiple mechanisms. Therefore, we intended to investigate its role in the progression of non-small cell lung cancer (NSCLC). Materials and Methods Firstly, quantitative real-time polymerase chain reaction (qRT-PCR) was used to test LINC00680 in NSCLC tissue and cell lines. Subsequently, A549 and H1299 cells were transfected with LINC00680 overexpressing plasmids and their proliferation and colony formation and apoptosis was tested by Transwell assay and flow cytometry. In addition, xenograft tumor experiments in nude mice also affirmed. Meanwhile, we predicted that miR-410-3p, LINC00680 and high-mobility group protein box 1(HMGB1) relationship by Starbase, dual-luciferase reporter and RIP assay. Finally, the carcinogenic effects of LINC00680 were reversed by ethyl pyruvate (EP), a specific inhibitor of HMGB1. Results LINC00680 was upregulated in NSCLC and was closely related to the malignancy and poor prognosis of NSCLC patients. LINC00680 promoted proliferation and colony formation and inhibited apoptosis of A549 and H1299 cells. In addition, overexpressing LINC00680 accelerated the growth of NSCLC cells in xenograft tumor experiments in nude mice also affirmed. Meanwhile, high-mobility group protein box 1(HMGB1) was astoundingly amplified in NSCLC and was negatively regulated by miR-410-3p. Further, HMGB1 acted as a downstream target of miR-410-3p, upregulating miR-410-3p to attenuate HMGB1, while LINC00680 strengthened the expression of HMGB1 in A549 and H1299 cells. Discussion Thus, these results indicated that LINC00680 was cancerogenic in NSCLC by upregulating HMGB1 via sponging miR-410-3p.

Abstract
Objective Gastric cancer (GC) is a gastrointestinal tumor. This study is aimed to explore the regulatory mechanism of long non-coding RNA BLACAT1 (BLACAT1)/microRNA-149-5p (miR-149-5p)/KIF2A cascade on GC. Methods The expression of BLACAT1, miR-149-5p and KIF2A in GC was detected by qRT-PCR. The proliferation, migration and invasion of GC cells in vitro were analyzed by MTT, wound-healing and transwell assay, respectively. The xenograft tumor model was constructed in nude mice to confirm the inhibition effect of BLACAT1 knockdown on GC in vivo. Then, dual-luciferase reporter assay was used to detect the interactions among BLACAT1, miR-149-5p and KIF2A. Western blot assay was performed to determine the protein expression of KIF2A. Results The expression of BLACAT1 and KIF2A was up-regulated in GC, but miR-149-5p expression was down-regulated. Silencing of BLACAT1 retarded the proliferation, migration and invasion of GC cells in vitro and the growth of tumor xenograft in vivo. Moreover, BLACAT1 acted as the molecular sponge of miR-149-5p to up-regulate KIF2A expression. At last, feedback experiments suggested that BLACAT1 accelerated the proliferation, migration and invasion of GC cells by regulating miR-149-5p/KIF2A axis. Conclusion BLACAT1 facilitated the tumorigenesis of GC through regulating miR-149-5p/KIF2A axis, which indicated BLACAT1/miR-149-5p/KIF2A cascade may be a new therapeutic target.

Br J Radiol 2020; 93:20190154.

Abstract
OBJECTIVE This work focused on the function role and underlying mechanism of BLACAT1 in regulating the radiosensitivity of head and neck squamous cell carcinoma (HNSCC) cells via PSEN1. METHODS BLACAT1 and PSEN1 expression in HNSCC tissues and cells were measured by qRT-PCR. Kaplan-Meier method and Spearman's correlation analysis determined the prognostic roles and association of BLCAT1 and PSEN1 in HNSCC. The impacts of BLACAT1 and PSEN1, alone and in combination, on radiosensitivity of HNSCC cells were separately assessed through CCK-8, colony formation, flow cytometry, western blot and γH2AX foci staining assays. RESULTS Our study disclosed that BLACAT1 and PSEN1 were both in association with poor prognosis and radioresistance of HNSCC cells. BLACAT1 knockdown improved the radiosensitivity of HNSCC cells by changing cellular activities containing repressed cell viability, accelerated cell apoptosis, induced cell cycle arrest, and stimulated DNA damage response. Further, we found that PSEN1 was positively correlated with BLACAT1. Rescue assays confirmed that BLACAT1 regulated the radiosensitivity of HNSCC cells by modulating PSEN1. CONCLUSION We revealed that BLACAT1 knockdown enhanced radioresistance of HNSCC cells via regulating PSEN1, exposing the probable target role of BLACAT1 in HNSCC. ADVANCES IN KNOWLEDGE This was the first time that the pivotal role of BLACAT1 was investigated in HNSCC, which provided a novel therapeutic direction for HNSCC patients.

Abstract
BACKGROUND Long non-coding RNAs are important regulators in cancer cell tumorigenesis. We have demonstrated in a prior study that lncRNA FTX is dysregulated in gastric cancer (GC). In this study, we aim to report gastric cancer-related lncRNA FTX as a main regulator in GC development and progression. METHODS In vitro and in vivo assays of FTX alterations have been performed to reveal a complex integrated phenotype affecting cell growth, migration, and invasion. lncRNA FTX expression levels in gastric cancer cells and normal cells were measured by RT-PCR. Luciferase reporter assays, Western blotting, and many immune, microscopy technologies were utilized to investigate the expressions of FTX- related proteins and RNAs. The functional role of FTX in cell growth, migration, and invasion were observed in vitro and in vivo. RESULTS We explored the underlying mechanisms of FTX in GC development, and the microRNAs' relationship with FTX. We found that FTX promoted cell proliferation, migration, and invasion, as well as tumor growth, and this effect could latterly be attenuated by miR-144. ZFX attenuated the effects of FTX/miR-144 axis by sponging with miR-144. CONCLUSION In summary, the above results support a model in which the FTX/miR-144/ZFX act as important effectors in GC tumorigenesis and progression, indicating new therapeutic methods in GC.

Abstract
BACKGROUND The expression of the long noncoding RNA LINC00483 is upregulated in lung adenocarcinoma (LUAD). However, its role in the progression of LUAD and the underlying mechanisms remain elusive. METHODS The expressions of LINC00483 and miR-204-3p were determined using quantitative real-time PCR. The correlation between the clinicopathological characteristics of LUAD patients and LINC00483 expression was analyzed using Pearson's χ2 test. A549 and PC-9 cells were transfected with small interfering RNA (siRNA) that specially targeting LINC00483 to assess the impact of its knockdown. Cell proliferation was assessed using the Cell Counting Kit-8 and clone forming assays. Cell migration and cell invasion were evaluated using a transwell assay. The levels of Snail, E-cadherin, N-cadherin and ETS1 proteins were determined via western blotting. The interaction between LINC00483 and miR-204-3p was analyzed using dual-luciferase, fluorescence in situ hybridization and RNA immunoprecipitation. RESULTS LINC00483 was upregulated in LUAD tissues and cell lines. Higher LINC00483 levels closely correlated to shorter survival times, advanced TNM stage, larger tumor size and positive lymph node metastasis. Cell proliferation, migration and invasion were suppressed after LINC00483 knockdown. LINC00483 mainly localized in the cytoplasm, where it acted as a sponge of miR-204-3p. ETS1 was validated as a downstream target of miR-204-3p and is thus regulated by LINC00483. CONCLUSION This study demonstrated that LINC00483 facilitates the proliferation, migration and invasion of LUAD cells by acting as a sponge for miR-204-3p, which in turn regulates ETS1.

Abstract
Long noncoding RNAs (lncRNAs) have been confirmed to be strongly associated with the progression of various types of cancer. LncRNA LINC01234 (LINC01234) is a newly identified tumor-related lncRNA whose upregulation has been confirmed in some tumors. However, its potential expressions and possible functions in non-small-cell lung cancer (NSCLC) have not been explored. In this study, we first found that LINC01234 expressions were distinctly upregulated in both NSCLC samples and cell lines using RT-PCR. Our group also showed that LINC01234 upregulations were modulated by nuclear transcription factor SP1. The results form clinical investigations indicated that high LINC01234 expressions were associated with positively lymph node metastasis and advanced tumor-metastasis-node (TMN) stage. Kaplan-Meier assays indicated that patients with NSCLC having high LINC01234 expressions tend to have unfavorable clinical prognosis. Using multivariate assays, it was confirmed that LINC01234 was an independent prognostic factor for patients with NSCLC. In vitro assays showed that inhibition of LINC01234 suppressed NSCLC cell proliferation, cell colony formation and metastasis, and greatly promoted apoptosis. Mechanistic investigations revealed LINC01234 promotes the progression of NSCLC cells by the modulation of miR-140 to positively regulate OTUB1 expression. Taken together our findings, they provided an exhaustive assay of LINC01234 in NSCLC and imperative clues for insights into the potential effects of lncRNAs-miRNAs regulatory network in NSCLC.

Abstract
Lung adenocarcinoma (LUAD) is typically featured by a low 5-year survival rate, hence there is a necessary to investigate new biomarkers in LUAD progression. Competing endogenous RNA (ceRNA) network has been widely reported in the regulation of tumor processes, which is also the main direction of this paper. Based on the data of GEPIA database, lncRNA MAFG-AS1 was upregulated in LUAD tissues, which was associated with poor prognosis of patients. Proliferation or apoptosis of LUAD cells were measured by CCK-8, EdU and caspase-3 activity assays followed by Western blot. The results indicated that silencing of MAFG-AS1 suppressed cell proliferation but induced cell apoptosis. RNA FISH staining showing the cytoplasmic localization of MAFG-AS1 in LUAD cells. Mechanism detection revealed that MAFG-AS1 served as a molecular sponge of miR-744-5p to upregulate its nearby gene MAF bZIP transcription factor G (MAFG) in LUAD cells. Functionally, MAFG overexpression attenuated the cellular processes mediated by MAFG-AS1 knockdown. In summary, this study unveiled the MAFG-AS1/miR-744-5p/MAFG axis in LUAD, providing a potent and promising therapeutic target for LUAD patients.

Abstract
Neuroblastoma (NB) is one of the most common extracranial solid tumors in children, which has complex molecular mechanisms. Increasing evidence has suggested that long noncoding RNAs (lncRNAs) account for NB pathogenesis. However, the function of small nucleolar RNA host gene 16 (SNHG16) in NB is currently unclear. In the present study, publically available data and clinical specimens were employed to verify the expression of SNHG16 in NB. Colony formation, real‑time cell proliferation and migration assays were performed to demonstrate the status of cellular proliferation and migration. Flow cytometry was used to examine cell cycle progression in SH‑SY5Y cells, and acridine orange/ethidium bromide staining and caspase‑3/7 activity measurements were applied to study cell apoptosis. To explore the underlying mechanism of SNHG16 function, an online database was used to identify potential RNA‑binding proteins that bind SNHG16. The expression of SNHG16 was revealed to be in line with the clinical staging of NB, and high SNHG16 expression was positively associated with poor clinical outcome. Furthermore, SNHG16 silencing inhibited cell proliferation, repressed migration, and induced cell cycle arrest at the G0/G1 phase in SH‑SY5Y cells. Additionally, apoptosis was undetectable in SH‑SY5Y cells following SNHG16 silencing. Bioinformatics analysis revealed that SNHG16 regulated cell proliferation in NB through transcriptional and translational pathways. These results suggested that SNHG16 may serve important roles in the development and progression of NB, and could represent a potential target for NB therapy.

Abstract
Glioma, an aggressive tumor in brain, presents a very poor prognosis. Emerging evidence has demonstrated that dysfunction of long noncoding RNAs (lncRNAs) is closely related to giloma development. However, the roles of lncRNA BLACAT1 in glioma are not unknown. In this study, we utilized in vitro and in vivo experiments to explore the effects of BLACAT1 on glioma cells. BLACAT1 levels were increased in glioma tissues. Upregulation of BLACAT1 showed poor prognosis. Silencing of BLACAT1 markedly repressed glioma proliferation, migration, and invasion, and suppressed glioma growth in vivo. We also illustrated that BLACAT1 worked as the sponge for miR-605-3p and promoted VASP expression. miR-605-3p was downregulated in glioma and repressed glioma proliferation, migration, and invasion. And VASP is upregulated and contributed to glioma progression. Summarily, this study highlights the important roles of BLACAT1/miR-605-3p/VASP axis in glioma progression.

Abstract
BACKGROUND/AIMS Emerging evidence have demonstrated that long noncoding RNAs are involved in the development and metastasis of various cancers including hepatocellular carcinoma (HCC). However, the role of LINC00339 in HCC progression is still unknown. METHODS The LINC00339 expression in HCC cancer cells (HUH7, HepG2, HUH-6, and SK-Hep-1) and tissues was assessed by quantitative real-time polymerase chain reaction (qRT-PCR). Functional experiments including cell counting Kit-8 wound-healing assay and transwell assay were used to explore the cell proliferation, migration, and invasion, respectively. The related molecular mechanisms were determined by Western blot. The RNA pull-down assay, luciferase reporters assay, qRT-PCR, and Western blot were performed to explore and confirm the interaction between LINC00339 and miR-152, between miR-152 and ROCK1. The role of LINC00339 in tumor formation and metastasis were explored through in vivo experiments. RESULTS LINC00339 was highly expressed in HCC tissues and cell lines. LINC00339 promoted the cell proliferation, migration, and invasion of HCC cells, while knockout of LINC00339 showed the opposite trends. The proliferation and migration of HCC cells induced by LINC00339 overexpression were mostly reversed after transfected with miR-152 mimics. LINC00339 exerted oncogenesis effect on HCC progression by targeting miR-152/ROCK1, and the expression of LINC00339 was negatively correlated with miR-152 expression and positively correlated with ROCK1 expression in clinical HCC samples. Moreover, we also proved that LINC00339 overexpression exacerbated the tumor formation and metastases in nude mice and LINC00339 silence showed the opposite results. CONCLUSION LINC00339 might act as a potential therapeutic target for HCC.

Abstract
Long non-coding RNAs (lncRNAs) are hypothesized to regulate numerous biological behaviors in human cancers. The present study aimed to explore the roles of lncRNA bladder cancer associated transcript 1 (BLACAT1) in glioma. The expression of BLACAT1 in glioma tissues and cell lines was determined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). CCK-8 assay, colony formation assay, wound healing assay and Transwell invasion assay were used to explore the roles of BLACAT1 in glioma cells. RT-qPCR and western blot analysis were used to determine the BLACAT1 molecular mechanism. The findings demonstrated that lncRNA BLACAT1 was overexpressed in glioma tissues and cell lines. High BLACAT1 expression was correlated with high tumor grade in glioma patients. Functional assays determined that BLACAT1 promoted glioma cell proliferation, migration, invasion and epithelial-mesenchymal transition in vitro. In addition, it was demonstrated that BLACAT1 activated the Wnt/β-catenin signaling pathway. In conclusion, BLACAT1 may serve as an oncogenic lncRNA in glioma progression via activation of the Wnt/β-catenin signaling pathway. Therefore, BLACAT1 may be a novel therapeutic target for glioma treatment.

LncRNA BLACAT1 May Serve as a Prognostic Predictor in Cancer: Evidence from a Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2019; 2019:1275491. [PMID: 31061820 PMCID: PMC6466934 DOI: 10.1155/2019/1275491] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/11/2019] [Revised: 03/12/2019] [Accepted: 03/18/2019] [Indexed: 02/06/2023]
Abstract
Background As a newly discovered lncRNA, bladder cancer-associated transcript 1 (BLACAT1) has been reported to correlate with poor clinical outcomes in several different cancers. This study aimed to evaluate its generalized predictive value for cancer prognosis. Materials and Methods We thoroughly searched PubMed, Embase, and Web of Science databases for eligible studies published until November 11, 2018, in which the relationship between BLACAT1 expression and cancer prognosis was explored. The analyses were performed using Review Manager Version 5.3 and Stata SE 12.0. The primary endpoints included overall survival (OS), pathological characteristics (TNM stage and tumor grade), lymph node metastasis (LNM), and distant metastasis. Results Ten studies containing 861 patients with 7 different cancerous diseases were eventually included. The results demonstrated that patients with high lncRNA BLACAT1 expression had a significantly shorter OS (HR: 1.82, 95% CI: 1.44-2.30, p < 0.00001) than patients with low lncRNA BLACAT1 expression. Moreover, elevated BLACAT1 expression was significantly associated with advanced TNM stage (OR: 2.29, 95% CI: 1.15-4.56, p = 0.005), high tumor grade (OR: 1.67, 95% CI: 1.11-2.53, p = 0.01), and lymph node metastasis (OR: 2.53, 95% CI: 1.80-3.57, p < 0.00001). Meanwhile, the expression of BLACAT1 had no significant association with age (p = 0.92), gender (p = 0.55), and smoking (p = 0.62). Conclusion High expression of lncRNA BLACAT1 may predict a poor prognosis in OS, TNM stage, tumor grade, and LNM. Its predictive roles were not significantly affected by age, gender, or smoking. Therefore, lncRNA BLACAT1 may serve as a promising predictor in cancer prognosis.

Abstract
Bladder cancer-associated transcript 1 (BLACAT1) is a novel identified long noncoding RNA (lncRNA) in bladder cancer, and has been suggested to function as an oncogenic lncRNA in several types of human cancer. However, its involvement in the progression of small-cell lung cancer (SCLC) remained unknown. The aim of our study was to investigate the clinical value and biological function in SCLC. In our results, BLACAT1 expression was increased in SCLC tissues and cell lines compared with paired adjacent normal tissues and bronchial epithelial cell lines, respectively. In addition, BLACAT1 high-expression was obviously associated with advanced clinical stage, large tumor size, more lymph node metastasis, present distant metastasis, and poor prognosis. Furthermore, multivariate analysis indicated that high-expression of BLACAT1 acted as an independent poor prognostic factor for overall survival in SCLC cases. The loss-of-function studies suggested that of BLACAT1 suppressed SCLC cell proliferation, migration, and invasion, and induced G0/G1 phase arrest. In conclusion, BLACAT1 is associated with the malignant status and prognosis in patients with SCLC, and functions as an oncogenic lncRNA in regulating cell proliferation and motility, suggesting BLACAT1 may act as a potential target for SCLC prevention and treatment.

Abstract
Background Breast cancer was dangerous to women health. A growing number of evidences indicate that long non-coding RNAs (lncRNAs) have many functions in the development and progression of breast cancer and may serve as the markers of diagnosis or prognosis. BLACAT1 is one of lncRNA and the roles of it in breast cancer is not clear. In this study, it is aimed to explore the roles and molecular mechanisms of BLACAT1 in breast cancer. Results We found BLACAT1 took part in breast cancer cell aggressive phenotype. The real-time PCR result showed that BLACAT1 was up-regulated in tumor tissues compared to adjacent normal tissues. The molecular mechanism experiments demonstrated that BLACAT1 down-regulation suppressed the proliferation and metastasis of human breast cancer cells by regulating miR-150-5p targeting CCR2. The clinical studies indicated that lack of BLACAT1 was related to tumor size, metastasis. Conclusion: The present study verified the involvement of the BLACAT1 in the mediation of cell survival and metastasis through miR-150-5p targeting CCR2 in breast cancer cells.

Abstract
OBJECTIVES The intention of our study was to investigate the relationship between miR-144-3p and EZH2 as well as the effects of their interaction on cell propagation and invasiveness in lung adenocarcinoma (LUAD). METHODS The expression levels of miR-144-3p and EZH2 in LUAD tissues and normal tissues were determined by qRT-PCR. The dual-luciferase reporter assay was utilized to validate the targeting relationship between miR-144-3p and EZH2. MTT assay and colony formation assay were performed to evaluate the viability and propagation of LUAD cells, while the effects of miR-144-3p and EZH2 on LUAD cell invasiveness were confirmed by transwell assay. Protein expression levels of VEGFA, MMP2, and MMP9 were measured by Western blot. Furthermore, xenograft tumor models were established to verify the effects of miR-144-3p on tumor formation and EZH2, VEGFA, MMP2 and MMP9 expressions in vivo. RESULTS miR-144-3P was downregulated in LUAD tissues, and overexpression of miR-144-3p inhibited propagation and invasiveness of LUAD cells. EZH2 was a target of miR-144-3p and was highly expressed in LUAD cells. Knockdown of EZH2 could suppress the propagation and invasion of LUAD cells. Increased miR-144-3p expression exerted an inhibitory effect on LUAD tumor formation in vivo. CONCLUSION Overexpression of miR-144-3p impeded the propagation and invasiveness of LUAD cells by targeting EZH2.

Abstract
Emerging evidence has illustrated the vital roles of long noncoding RNAs (lncRNAs) in human cancers. However, the role of lncRNAs in non-small cell lung cancer (NSCLC) is still elusive and poorly understood. In the current study, our team conducted extensive experiments to identify the role of long intergenic nonprotein coding (LINC01296) on NSCLC tumorigenesis. The results illustrated that the elevated LINC01296 expression in NSCLC tissue specimens and cell lines were closely correlated with the poor prognosis of patients with NSCLC. Functional studies revealed that LINC01296 knockdown silenced by small interfering RNAs inhibited proliferation, accelerated apoptosis in vitro, and impaired tumor growth in vivo. Mechanical studies showed that INC01296 harbored miR-598, acting as a microRNA "sponge." Besides, miR-598 targeted the 3'-UTR of Twist1. Interestingly, transcription factor Twist1 could bind with the promoter of INC01296 and activate its transcriptional level. In summary, we conclude that INC01296/miR-598/Twist1 constitutes a positive feedback loop to promote the tumorigenesis of NSCLC, providing a novel insight and a valuable therapeutic strategy.

Abstract
Long non-coding RNAs (lncRNAs) have been validated to play important role in multiple cancers, including non-small cell lung cancer (NSCLC). In present study, our team investigate the biologic role of SNHG15 in the NSCLC tumorigenesis. LncRNA SNHG15 was significantly upregulated in NSCLC tissue samples and cells, and its overexpression was associated with poor prognosis of NSCLC patients. In vitro, loss-of-functional cellular experiments showed that SNHG15 silencing significantly inhibited the proliferation, promoted the apoptosis, and induced the cycle arrest at G0//G1 phase. In vivo, xenograft assay showed that SNHG15 silencing suppressed tumor growth of NSCLC cells. Besides, SNHG15 silencing decreased CDK14 protein expression both in vivo and vitro. Bioinformatics tools and luciferase reporter assay confirmed that miR-486 both targeted the 3'-UTR of SNHG15 and CDK14 and was negatively correlated with their expression levels. In summary, our study conclude that the ectopic overexpression of SNHG15 contribute to the NSCLC tumorigenesis by regulating CDK14 protein via sponging miR-486, providing a novel insight for NSCLC pathogenesis and potential therapeutic strategy for NSCLC patients.

Abstract
Non-small cell lung cancer (NSCLC) is one of leading causes of cancer-related death worldwide. Long noncoding RNAs (lncRNAs) has been identified to modulate the tumorigenesis of NSCLC. However, the precise molecular mechanism of lncRNAs in the course is still unclear. Results showed that LINC00339 was significantly up-regulated in NSCLC tissue and cells, which indicated the poor prognosis of NSCLC patients. Loss-of-function experiments showed that LINC00339 silencing inhibited the proliferation and invasion, accelerated the apoptosis, and suppressed the tumor growth of NSCLC cells in vitro and in vivo. Luciferase reporter assay and RNA immunoprecipitation (RIP) revealed that LINC00339 promoted the NSCLC progression via FOXM1 via targeting miR-145. In conclusion, our results identify the important role of the LINC00339/miR-145/FOXM1 axis in the NSCLC tumorigenesis, providing neoteric mechanism for the NSCLC tumorigenesis.

Abstract
This study aimed to explore the effects of lncRNA BCAR4 on the viability and aggressiveness of non-small cell lung cancer (NSCLC) cells. qRT-PCR was used to determine the expression of BCAR4 and GLI2 downstream genes in NSCLC tissues and cell lines. Chromatin isolation by RNA purification (CHIRP) and Western blot were employed to measure the expression of the GLI2 downstream proteins. Ki-67 expression in nude mice tumors was tested by immunohistochemistry. MTT assay, wound healing assay, and Transwell assay were used to assess NSCLC cell viability and aggressiveness, respectively. Tumor xenograft was conducted to determine the effects of BCAR4 and GLI2 on NSCLC tumorigenesis in vivo. The expression of BCAR4 in NSCLC tissues and cells was significantly higher than the normal level. The overexpression of BCAR4 promoted NSCLC cell viability, migration, and invasion. The suppression of BCAR4 and GLI2 showed the opposite effects. The overexpression of BCAR4 led to an increase in the expression of GLI2 downstream proteins, while the suppression of BCAR4 and GLI2 reduced their expression. In a tumor xenograft assay, the tumors in mice of the BCAR4 group showed the biggest volume, while those in mice of the si-GLI2 group showed the smallest volume. Ki-67 showed much higher levels in the BCAR4 overexpression group but much lower levels in the si-GLI2 group. In summary, the cooperative mechanism of lncRNA BCAR4 and GLI2 might provide a new opportunity for treating NSCLC.

Abstract
Noncoding RNA play important roles in various biological processes and diseases, including cancer. The expression profile of circular RNA (circRNA) has not been systematically investigated in lung adenocarcinoma (LUAD). In this study, we performed genomewide transcriptome profiling of coding genes, long noncoding RNA (lncRNA), and circRNA in paired LUAD and nontumor tissues by ribosomal RNA‐depleted RNA sequencing. The detected reads were first mapped to the human genome to analyze expression of coding genes and lncRNA, while the unmapped reads were subjected to a circRNA prediction algorithm to identify circRNA candidates. We identified 1282 differentially expressed coding genes in LUAD. Expression of 19 023 lncRNA was detected, of which 244 lncRNAs were differentially expressed in LUAD. AFAP1‐AS1, BLACAT1, LOC101928245, and FENDRR were most differentially expressed lncRNAs in LUAD. Also identified were 9340 circRNA candidates with ≥ 2 backspliced, including 3590 novel circRNA transcripts. The median length of circRNA was ~ 530 nt. CircRNA are often of low abundance, and more than half of circRNAs we identified had < 10 reads. Agarose electrophoresis and Sanger sequencing were used to confirm that four candidate circRNA were truly circular. Our results characterized the expression profile of coding genes, lncRNA, and circRNA in LUAD; 9340 circRNAs were detected, demonstrating that circRNA are widely expressed in LUAD. Database The raw RNA sequencing data have been submitted to Gene Expression Omnibus (GEO) database and can be accessed with the ID GEO: http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE104854.

Abstract
Most non-small cell lung cancer patients with active epidermal growth factor receptor (EGFR) mutation will eventually acquire drug resistant to EGFR tyrosine kinase inhibitors, such as gefitinib, resulting in disease progression, which involves a variety of complex mechanisms. Up to now, the molecular mechanisms of long non-coding RNAs mediated EGFR-TKIs resistance remains poorly understood. This review aims to outline the current state of information on lncRNAs and progress on its role in EGFR-TKIs resistance in non-small cell lung cancer.

Abstract
Long non-coding RNAs (lncRNAs) have emerged as novel gene regulators in multiple tumorigenesis and chemoresistance. However, their potential roles and molecular mechanisms in gastric cancer chemoresistance remain unclear. In present study, our team investigated the role and potential regulatory mechanism of lncRNA s bladder cancer associated transcript-1 (BLACAT1) in the gastric cancer chemoresistance. Results showed that BLACAT1 expression was up-regulated in the oxaliplatin (OXA) resistant gastric cancer tissue and cells compared with OXA-sensitive tissue and parental cell lines. In vitro, BLACAT1 knockdown decreased the expression levels of drug resistance related genes and ABCB1 protein. Besides, BLACAT1 knockdown significantly promoted apoptosis and down-regulated the invasion and the IC50 value of oxaliplatin. In vivo, BLACAT1 knockdown suppressed the tumor growth of gastric cancer cells. Bioinformatics tools and luciferase assay indicated that miR-361 both targeted 3?-UTR of BLACAT1 and ABCB1mRNA, suggesting the BLACAT1/miR-361/ABCB1 regulatory pathway. In summary, our results conclude that BLACAT1 accelerates the oxaliplatin-resistance of gastric cancer via promoting ABCB1 protein expression by targeting miR-361, providing a novel insight for the chemoresistance of gastric cancer.
