Abstract
BACKGROUND Cancer-associated fibroblasts (CAFs) orchestrate a supportive niche that fuels cancer metastatic development in non-small cell lung cancer (NSCLC). Due to the heterogeneity and plasticity of CAFs, manipulating the activated phenotype of fibroblasts is a promising strategy for cancer therapy. However, the underlying mechanisms of fibroblast activation and phenotype switching that drive metastasis remain elusive. METHODS The clinical implications of fibroblast activation protein (FAP)-positive CAFs (FAP+CAFs) were evaluated based on tumor specimens from NSCLC patients and bioinformatic analysis of online databases. CAF-specific circular RNAs (circRNAs) were screened by circRNA microarrays of primary human CAFs and matched normal fibroblasts (NFs). Survival analyses were performed to assess the prognostic value of circNOX4 in NSCLC clinical samples. The biological effects of circNOX4 were investigated by gain- and loss-of-function experiments in vitro and in vivo. Fluorescence in situ hybridization, luciferase reporter assays, RNA immunoprecipitation, and miRNA rescue experiments were conducted to elucidate the underlying mechanisms of fibroblast activation. Cytokine antibody array, transwell coculture system, and enzyme-linked immunosorbent assay (ELISA) were performed to investigate the downstream effectors that promote cancer metastasis. RESULTS FAP+CAFs were significantly enriched in metastatic cancer samples, and their higher abundance was correlated with the worse overall survival in NSCLC patients. A novel CAF-specific circRNA, circNOX4 (hsa_circ_0023988), evoked the phenotypic transition from NFs into CAFs and promoted the migration and invasion of NSCLC in vitro and in vivo. Clinically, circNOX4 correlated with the poor prognosis of advanced NSCLC patients. Mechanistically, circNOX4 upregulated FAP by sponging miR-329-5p, which led to fibroblast activation. Furthermore, the circNOX4/miR-329-5p/FAP axis activated an inflammatory fibroblast niche by preferentially inducing interleukin-6 (IL-6) and eventually promoting NSCLC progression. Disruption of the intercellular circNOX4/IL-6 axis significantly suppressed tumor growth and metastatic colonization in vivo. CONCLUSIONS Our study reveals a role of the circRNA-induced fibroblast niche in tumor metastasis and highlights that targeting the circNOX4/FAP/IL-6 axis is a promising strategy for the intervention of NSCLC metastasis.

Abstract
Bladder cancer (BC) is featured as the second most common malignancy of the urinary tract worldwide with few treatments leading to high incidence and mortality. It stayed a virtually intractable disease, and efforts to identify innovative and effective therapies are urgently needed. At present, more and more evidence shows the importance of non-coding RNA (ncRNA) for disease-related study, diagnosis, and treatment of diverse types of malignancies. Recent evidence suggests that dysregulated functions of ncRNAs are closely associated with the pathogenesis of numerous cancers including BC. The detailed mechanisms underlying the dysregulated role of ncRNAs in cancer progression are still not fully understood. This review mainly summarizes recent findings on regulatory mechanisms of the ncRNAs, long non-coding RNAs, microRNAs, and circular RNAs, in cancer progression or suppression and focuses on the predictive values of ncRNAs-related signatures in BC clinical outcomes. A deeper understanding of the ncRNA interactive network could be compelling framework for developing biomarker-guided clinical trials.

lncRNA ZFAS1 Positively Facilitates Endothelial Ferroptosis via miR-7-5p/ACSL4 Axis in Diabetic Retinopathy. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:9004738. [PMID: 36092160 PMCID: PMC9453005 DOI: 10.1155/2022/9004738] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 08/05/2022] [Accepted: 08/12/2022] [Indexed: 11/29/2022]
Abstract
Accumulating evidence has suggested the significant role of long noncoding RNAs (lncRNA) in regulating ferroptosis, while its regulatory mechanism in diabetic retinopathy (DR) remains unelucidated. In this work, we first demonstrated that lncRNA zinc finger antisense 1 (ZFAS1) is upregulated in high glucose-cultured human retinal endothelial cells (hRECs) and ZFAS1 inhibition attenuated high glucose- (HG-) induced ferroptosis, which was evidenced by cell viability, total iron and ferrous iron levels, reactive oxygen species (ROS) level, and Glutathione Peroxidase 4 (GPX4) expression detection. Mechanistically, we validated that ZFAS1 may act as a competing endogenous RNA by competitively binding with microRNA-7-5p (miR-7-5p) and modulating the expression of its downstream molecule acyl-CoA synthetase long-chain family member 4 (ACSL4), which is now identified as a classic driver gene of ferroptosis process. In conclusion, our results demonstrate that HG-induced ZFAS1 elevation activates ferroptosis in hRECs and the ZFAS1/miR-7-5p/ACSL4 axis may serve as a therapeutic target for endothelial dysfunction in DR.

Clinical significance and biological effect of ZFAS1 in Hirschsprung's disease and preliminary exploration of its underlying mechanisms using integrated bioinformatics analysis. Ir J Med Sci 2022; 191:2669-2675. [PMID: 34993837 DOI: 10.1007/s11845-021-02906-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Accepted: 12/22/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND The pathogenesis of Hirschprung's disease (HSCR) remains largely unknown. The lncRNA ZNFX1 antisense RNA 1 (ZFAS1) has been found to have vital regulatory roles in a number of diseases. However, the association between ZFAS1 and HSCR has not been reported. AIMS The present study was aimed at investigating the expression pattern and biological function and underlying mechanisms of ZFAS1 in HSCR. METHODS The expression of ZFAS1 was detected in surgical excision samples of 30 children diagnosed with HSCR and 30 control cases. Functional experiments were conducted after over-expression or knockdown of ZFAS1 in human neuronal cell line SH-SY-5Y. Multiple bioinformatics databases and tools were used to explore the potential regulatory mechanisms of ZFAS1 in HSCR. RESULTS Compared with the control group, the HSCR group has a significantly higher level of ZFAS1(P = 0.0012). The area under the curve (AUC) of the receiver operating characteristic (ROC) curve was 0.7133 (P = 0.0045), which indicated good biomarker potency of ZFAS1 in HSCR. Functionally, over-expression of ZFAS1 significantly inhibited cell proliferation, whereas knockdown of ZFAS1 promoted cell proliferation and colony formation of SH-SY-5Y cells. Using multiple databases, a competing endogenous RNA (ceRNA) network, containing ZFAS1,13 candidate miRNAs, and 110 potential gene targets, was established. Further enrichment analysis suggested that ZFAS1 may regulate a number of genes and signaling pathways that were crucial for neuron development. CONCLUSIONS Our findings revealed that ZFAS1 may participate in the pathogenesis of HSCR through regulating neuron functions. Bioinformatics analysis highlighted an important perspective for the following mechanical researches.

Abstract
Bladder cancer (BCa) is one of the 10 most common cancers with high morbidity and mortality worldwide. Long noncoding RNAs (lncRNAs), a large class of noncoding RNA transcripts, consist of more than 200 nucleotides and play a significant role in the regulation of molecular interactions and cellular pathways during the occurrence and development of various cancers. In recent years, with the rapid advancement of high-throughput gene sequencing technology, several differentially expressed lncRNAs have been discovered in BCa, and their functions have been proven to have an impact on BCa development, such as cell growth and proliferation, metastasis, epithelial-mesenchymal transition (EMT), angiogenesis, and drug-resistance. Furthermore, evidence suggests that lncRNAs are significantly associated with BCa patients' clinicopathological characteristics, especially tumor grade, TNM stage, and clinical progression stage. In addition, lncRNAs have the potential to more accurately predict BCa patient prognosis, suggesting their potential as diagnostic and prognostic biomarkers for BCa patients in the future. In this review, we briefly summarize and discuss recent research progress on BCa-associated lncRNAs, while focusing on their biological functions and mechanisms, clinical significance, and targeted therapy in BCa oncogenesis and malignant progression.

Isolation and Identification of Long Non-Coding RNAs in Exosomes Derived from the Serum of Colorectal Carcinoma Patients. BIOLOGY 2021; 10:biology10090918. [PMID: 34571795 PMCID: PMC8465981 DOI: 10.3390/biology10090918] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 08/20/2020] [Accepted: 08/22/2020] [Indexed: 12/12/2022]
Abstract
Simple Summary Treatment regimens for patients with advanced disease are limited and the mortality rate is high in these patients. A better understanding on pathogenesis and progression of cancer is critical for the development of new treatment strategies. In colorectal cancer (CRC), exosomes (secreted vesicles from cells) and long non-coding RNAs (lncRNAs) have been shown to play significant roles in disease development and progression. Long non-coding RNAs (lncRNAs) are present in the exosomes of serum and their profiles may potentially be useful as novel biomarkers for CRC patients and may provide a new insight in the pathogenesis and progression of CRC. Here, we compared the expression profiles of exosomal lncRNAs between non-cancer individuals and patients with colorectal carcinoma. The relative expression level of LINC00152 was found to be significantly lower in exosomes from sera of CRC patients as compared to non-cancer individuals whereas lncRNA H19 was significantly up-regulated in advanced-stages (stage III and IV) of CRC as compared to early-stages (stage I and II). Our data suggest that LINC00152 and H19 may play important roles in pathogenesis and progression of CRC. Abstract Long non-coding RNAs (lncRNAs) are non-coding RNAs consisting of more than 200 nucleotides in length. LncRNAs present in exosomes may play a critical role in the cellular processes involved in cancer pathogenesis and progression including proliferation, invasion, and migration of tumor cells. This paper aims to identify the differential expression of exosomal lncRNAs derived from the sera of non-cancer individuals and patients diagnosed with colorectal carcinoma. These differentially-expressed exosomal serum lncRNAs may provide an insight into the pathogenesis and progression of colorectal cancer (CRC). Serum exosomes and exosomes from SW480-7 cell culture supernatants were isolated and viewed by transmission electron microscope (TEM). The particle size distribution and protein markers of exosomes derived from SW480-7 were further analyzed using the Zetasizer Nano S instrument and western blotting technique. TEM showed that exosomes derived from serum and SW480-7 cells were round vesicles with sizes ranging from 50–200 nm. The exosomes derived from SW480-7 had an average diameter of 274.6 nm and contained the exosomal protein, ALIX/PDCD6IP. In our clinical studies, six lncRNAs, namely GAS5, H19, LINC00152, SNHG16, RMRP, and ZFAS1 were detected in the exosomes from sera of 18 CRC patients. Among these six lncRNAs, the expression level of LINC00152 was found to be significantly lower in CRC patients as compared to non-cancer individuals (p = 0.04) while lncRNA H19 was significantly up-regulated in advanced-stages (stage III and IV) of CRC (p = 0.04) as compared to early-stages (stage I and II). In conclusion, the detection of lower LINC00152 in exosomes of sera from CRC patients versus non-cancer individuals and H19 upregulation in advanced stages suggests that they may play important roles in pathogenesis and progression of CRC.

Abstract
Residing on chromosome 20q13.13, Zinc Finger NFX1-Type Containing 1 (ZNFX1) antisense RNA 1 (ZFAS1) is a transcript which has been primarily recognized as a modulator of differentiation of alveolar and epithelial cell in the mammary gland. This long non-coding RNA (lncRNA) partakes in the molecular cascades leading to several non-neoplastic conditions such as osteoarthritis, epilepsy, rheumatoid arthritis, atherosclerosis, pulmonary fibrosis, myocardial infarction, and cardiac dysfunction. More importantly, ZFAS1 is considered as an oncogene in almost all types of cancers. Using expression amounts of ZFAS1, it is possible to forecast the clinical outcome of patients with different neoplasms such as colorectal cancer, gastric cancer, cholangiocarcinoma, hepatoblastoma, and other types of cancer. We describe the role of ZFAS1 in the development of neoplastic and non-neoplastic disorders.

Abstract
The incidence and mortality rate of nonsmall cell lung cancer (NSCLC) are continuously increasing. Recently, the important roles of long noncoding ribonucleic acid (lncRNA) zinc finger antisense1 (ZFAS1) in the development of many disease have been proved. However, the roles of ZFAS1 in NSCLC are still not completely understood. Thus, this study aimed to explore the potential roles and underlying mechanisms of lncRNA ZFAS1 in the progression of NSCLC. Our results demonstrated that lncRNA ZFAS1 expression was significantly upregulated in NSCLC tissues and cell lines. Loss-of-function experiments revealed that lncRNA ZFAS1 inhibition could remarkably suppress NSCLC cells proliferation in vitro. Bioinformatic analysis and luciferase reporter assay revealed that lncRNA ZFAS1 directly interacted with miR-590-3p. Rescue experiments showed that miR-590-3p inhibitor reversed the cell proliferation function of lncRNA ZFAS1 knockdown in vitro. Furthermore, we confirmed that lncRNA ZFAS1 inhibited cell division cycle 42 (Cdc42) expression by regulating of miR-590-3p in NSCLC cells. Therefore, our study indicates that lncRNA ZFAS1/miR-590-3p axis is involved in NSCLC cell proliferation. It also suggests that lncRNA ZFAS1 is a putative tumor oncogene in NSCLC.

Abstract
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease characterized by joint disorders. Long non-coding RNA zinc finger antisense 1 (ZFAS1) is aberrantly expressed in numerous human diseases, including RA. The present study aimed to investigate the functions and underlying mechanisms of ZFAS1 in RA. Reverse transcription-quantitative PCR was performed to determine the expression levels of ZFAS1, microRNA (miR)-3926 and follistatin-like protein 1 (FSTL1). MTT assay, flow cytometric analysis and Transwell assay were performed to examine the proliferation, apoptosis, migration and invasion of fibroblast-like synoviocytes (FLSs), respectively. Western blotting was employed to measure the protein expression levels of cleaved caspase-3, interleukin (IL)-6, IL-1β, tumor necrosis factor-α and FSTL1. Dual-luciferase reporter assay was performed to verify the interaction between miR-3926 and ZFAS1 or FSTL1. The results demonstrated that ZFAS1 and FSTL1 were upregulated, and miR-3926 was downregulated in RA synovial tissues and RA-FLSs. ZFAS1 knockdown suppressed cell proliferation, migration, invasion and inflammatory cytokine production, and induced apoptosis in RA-FLSs. ZFAS1 acted as a sponge for miR-3926, and ZFAS1 overexpression abolished the impact of miR-3926 on the development of RA-FLSs. FSTL1 was a direct target of miR-3926, and the effect of FSTL1 knockdown on the progression of RA-FLSs was rescued by miR-3926 inhibition. Furthermore, ZFAS1 regulated FSTL1 expression levels via sponging miR-3926 in RA-FLSs. In conclusion, ZFAS1 knockdown inhibited RA-FLS proliferation, migration, invasion and inflammatory cytokine production, and induced apoptosis in RA via the miR-3926/FSTL1 axis.

Long non-coding RNA ZFAS1 exerts a protective role to alleviate oxygen and glucose deprivation-mediated injury in ischemic stroke cell model through targeting miR-186-5p/MCL1 axis. Cytotechnology 2021; 73:605-617. [PMID: 34349350 DOI: 10.1007/s10616-021-00481-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Accepted: 06/08/2021] [Indexed: 02/07/2023] Open
Abstract
In recent years, accumulating articles have revealed that long non-coding RNAs (lncRNAs) play crucial roles in ischemic stroke (IS). A previous study found that lncRNA zinc finger antisense 1 (ZFAS1) was down-regulated in IS patients compared with healthy controls. However, the precise function of ZFAS1 in IS and its associated mechanism remain unclear. Cell viability was assessed by cell counting kit-8 (CCK8) assay. Cell apoptosis was analyzed by flow cytometry. Western blot assay and quantitative real-time polymerase chain reaction (qRT-PCR) were conducted to measure protein and RNA expression. The interaction between microRNA-186-5p (miR-186-5p) and ZFAS1 or MCL1 apoptosis regulator, BCL2 family member (MCL1) was confirmed by dual-luciferase reporter assay, RNA-pull down assay and RNA immunoprecipitation (RIP) assay. IS cell model was established through exposing N2a cells to oxygen and glucose deprivation (OGD). OGD exposure restrained the viability and induced the apoptosis of N2a cells. OGD exposure down-regulated the expression of ZFAS1 and up-regulated the level of miR-186-5p in a time-dependent manner. ZFAS1 overexpression alleviated OGD-mediated injury in IS cell model. MiR-186-5p was identified as a direct target of ZFAS1, and OGD-induced injury in IS cell model was attenuated by the silence of miR-186-5p. MiR-186-5p interacted with the 3' untranslated region (3'UTR) of MCL1 messenger RNA (mRNA). ZFAS1 positively regulated MCL1 mRNA expression by sequestering miR-186-5p in N2a cells. ZFAS1 overexpression-mediated protective effects in IS cell model were partly overturned by the overexpression of miR-186-5p. MCL1 silencing partly counteracted the protective effects mediated by miR-186-5p silencing in IS cell model. In conclusion, ZFAS1 overexpression exerted a protective role in IS cell model to attenuate OGD-induced injury through targeting miR-186-5p/MCL1 axis. ZFAS1/miR-186-5p/MCL1 signaling might be a novel diagnostic marker and promising treatment target for IS patients.

Abstract
Bladder cancer is one of the leading causes of cancer deaths worldwide. Early detection of lymph node metastasis of bladder cancer is essential to improve patients' prognosis and overall survival. Current diagnostic methods are limited, so there is an urgent need for new specific biomarkers. Non-coding RNA and m6A have recently been reported to be abnormally expressed in bladder cancer related to lymph node metastasis. In this review, we tried to summarize the latest knowledge about biomarkers, which predict lymph node metastasis in bladder cancer and their mechanisms. In particular, we paid attention to the impact of non-coding RNA on lymphatic metastasis of bladder cancer and its specific molecular mechanisms, as well as some prediction models based on imaging, pathology, and biomolecules, in an effort to find more accurate diagnostic methods for future clinical application.

Abstract
AIMS The purpose of this paper is to unearth the ceRNA regulatory mechanism of SNHG7 in bladder cancer (BCa). MATERIALS AND METHODS The expression of SNHG7 in BCa cells was uncovered by qRT-PCR. The biological functions of SNHG7 in BCa cells were explored by CCK-8 assay, colony formation assay, flow cytometry analysis, wound healing assay and transwell assay. Luciferase reporter assay and RIP assay were applied to analyze the interaction of ELK1 with SNHG7 or miR-2682-5p. KEY FINDINGS SNHG7 was conspicuously highly expressed in BCa tissues and cells. The upregulated expression of SNHG7 was related with poor prognosis in BCa patients. Moreover, SNHG7 exerted oncogenic functions in BCa through enhancing cell growth, migration and invasion. ELK1 increased the level of SNHG7 by binding with the promoter region of SNHG7. SNHG7 strengthened the expression of ELK1 via acting as a sponge of miR-2682-5p. Both ELK1 and miR-2682-5p involved in the SNHG7-mediated BCa progression. SIGNIFICANCE ELK1/SNHG7/miR-2682-5p feedback loop enhances cell growth, migration and invasion in BCa.

Abstract
Non-small cell lung cancer (NSCLC) is the main type of lung malignancy. Early diagnosis and treatments for NSCLC are far from satisfactory due to the limited knowledge of the molecular mechanisms regarding NSCLC progression. Long noncoding RNA (lncRNA) ZNFX1 antisense RNA1 (ZFAS1) has been implicated for its functional role in the progression of malignant tumors. This study aimed to determine the ZFAS1 expression from lung cancer clinical samples and to explore the molecular mechanisms underlying ZFAS1-modulated NSCLC progression. Experimental assays revealed that clinical samples and cell lines of lung malignant tumors showed an upregulation of ZFSA1. ZFAS1 expression was markedly upregulated in the lung tissues from patients with advanced stage of this malignancy. The loss-of-function assays showed that knockdown of ZFAS1-suppressed NSCLC cell proliferative, as well as invasive potentials, increased NSCLC cell apoptotic rates in vitro and also attenuated tumor growth of NSCLC cells in the nude mice. Further experimental evidence showed that ZFAS1 inversely affected miR-150-5p expression and positively affected high-mobility group AT-hook 2 (HMGA2) expression in NSCLC cell lines. MiR-150-5p inhibition or HMGA2 overexpression counteracted the effects of ZFAS1 knockdown on NSCLC cell proliferative, invasive potentials and apoptotic rates. In light of examining the clinical lung cancer samples, miR-150-5p expression was downregulated and the HMGA2 expression was highly expressed in the lung cancer tissues compared with normal ones; the ZFAS1 expression showed a negative correlation with miR-150-5p expression but a positive correlation with HMGA2 expression in lung cancer tissues. To summarize, we, for the first time, demonstrated the inhibitory effects of ZFAS1 knockdown on NSCLC cell progression, and the results from mechanistic studies indicated that ZFAS1-mediated NSCLC progression cells via targeting miR-150-5p/HMGA2 signaling.

Abstract
Background Long non-coding RNAs (lncRNAs) have been certified to be involved in the occurrence and growth of diverse cancers, including CRC. The purpose of the research was to explore the effects of lncRNA KCNQ1 overlapping transcript 1 (KCNQ1OT1) on proliferation, migration, invasion, and apoptosis in CRC cells and its mechanism. Methods The levels of KCNQ1OT1 and miR-329-3p were examined by quantitative real-time polymerase chain reaction (qRT-PCR) in CRC tissues and cells. The mRNA and protein levels of catenin delta-1 (CTNND1) were measured by qRT-PCR and western blot analysis, respectively. The targets of KCNQ1OT1 and miR-329-3p were predicted by online software and confirmed by luciferase reporter assay. The cell proliferation, migration, invasion, and apoptosis were examined using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT), transwell, and apoptosis assay. The expression levels of CyclinD1, Bcl-2, MMP9, Cleaved-casp-3, and E-cadherin in SW480 and LS1034 cells were gauged by western blot analysis. Xenograft tumor model was structured to prove the biological role of KCNQ1OT1 of CRC in vivo. Results The levels of KCNQ1OT1 and CTNND1 were significantly increased in CRC tissues and cells. Knockdown of KCNQ1OT1 suppressed proliferation, migration, invasion, and induced apoptosis in CRC cells. Conversely, CTNND1 overexpression reversed the impact of KCNQ1OT1 knockdown on CRC cells. Moreover, CTNND1 was verified as a direct target of miR-329-3p, and miR-329-3p could specially bind to KCNQ1OT1. Also, the down-regulation of KCNQ1OT1 triggered the CRC progress by up-regulating CTNND1 expression in CRC cells. Besides, KCNQ1OT1 knockdown inhibited CRC tumor growth through the miR-329-3p/CTNND1 axis in vivo. Conclusion Our results indicated that KCNQ1OT1 could positively regulate CTNND1 expression by sponging miR-329-3p, thereby boosting the progression of CRC. Our findings provided the underlying therapy targets for CRC.

Abstract
Melanoma is the deadliest form of skin cancer and one of the most aggressive cancers. ZFAS1 is a newly identified lncRNA, playing an oncogenic role in several types of cancer. The present study aimed to investigate the function and mechanism of ZFAS1-induced regulation of melanoma. ZFAS1 expression was increased in melanoma tissues and cells compared with normal controls. ZFAS1 expression in metastatic tissues was higher than that in nonmetastatic subjects. Higher expression of ZFAS1 predicted lower survival rates. Knockdown of ZFAS1 decreased proliferation, increased apoptosis, decreased migration and invasion, and reduced epithelial-mesenchymal transition potential in melanoma cells. Moreover, ZFAS1 knockdown inhibited tumor growth in nude mice. There was a direct binding between ZFAS1 and miR-150-5p. ZFAS1 negatively regulated miR-150-5p expression and upregulation of miR-150-5p was involved in ZFAS1 knockdown-induced effect on proliferation, apoptosis, migration, and invasion. Using bioinformatics, we predicted the binding between RAB9A and miR-150-5p, and the direct interaction between RAB9A and miR-150-5p was confirmed by luciferase reporter and RNA immunoprecipitation assays. We also showed that RAB9A expression was regulated negatively by miR-150-5p, but was regulated positively by ZFAS1. Downregulation of RAB9A significantly inhibited the increase in proliferation, decrease in apoptosis, and increase in migration and invasion induced by miR-150-5p inhibitors. Moreover, RAB9A knockdown decreased proliferation, increased apoptosis, and decreased migration and invasion in melanoma cells. In summary, we confirmed the tumor-promoting role of ZFAS1 in melanoma and provide evidence for the role and mechanism of the ZFAS1/miR-150-5p/RAB9A axis. These findings may lead to novel therapeutic strategies for melanoma.

Abstract
LncRNA (Long non-coding RNA) ZFAS1 (zinc finger antisense 1) functions as the oncogene in multiple cancers, including gastric cancer. However, its function and underlying mechanism in the GCA (gastric cardia adenocarcinoma), the most aggressive type of gastric cancer, remain unknown. We demonstrated here that the LncRNA ZFAS1 was up-regulated in GCA tissues. Furthermore, the elevated level of ZFAS1 was significantly associated with the GCA metastasis and cancer recurrence. It was also demonstrated to be an independent prognostic indicator of disease-free survival and overall survival for GCA patients. RNA sequencing showed that the up-regulated ZFAS1 was tightly associated with the down-regulated hypoxia inducible factor 1 (HIF1) and up-regulated EPAS1 (Endothelial PAS domain protein 1, also known as HIF2). In vitro studies showed that the ZFAS1 could bind to EPAS1, enhance its abilities to epigenetically silence the HIF1, and promote its own expression in GCA cell lines. In the animal model, co-delivering the EPAS1 and the ZFAS1 antisense oligos could significantly boost up their therapeutic effects on tumor growth. Thus, targeting ZFAS1 and EPAS1 might be an alternative therapeutic option in GCA.

Abstract
BACKGROUND As the seventh most common urologic carcinoma worldwide, approximately 430,000 patients are diagnosed with bladder cancer (BC) every year. Increasing evidence indicates that long noncoding RNAs (lncRNAs) play crucial roles in the progression of BC. OBJECTIVES This study is aimed to explore the function and mechanism of CASC9 in BC. METHODS Bioinformatics analysis and experiments including RT-qPCR, luciferase reporter, Cell Counting Kit-8 assay, Western blot, RNA immunoprecipitation assay, and TUNEL staining were applied to explore the function and mechanism of CASC9 in BC tissues and cell lines. RESULTS Our study demonstrated that CASC9 was upregulated in BC tissues and cell lines. Moreover, we found that CASC9 knockdown notably decreased proliferation while increased apoptotic rate in BC cells. Mechanistically, bioinformatics prediction and following experiments indicated that CASC9 worked as a competing endogenous RNA (ceRNA) of CBX2 through sponging miR-497-5p. Meanwhile, we recognized that CASC9 and miR-497-5p negatively regulated each other in a mutual way. Furthermore, we found that miR-497-5p shared binding site with CBX2. In addition, miR-497-5p could negatively regulated CBX2, while CASC9 could positively regulated CBX2. Rescue assays reveled that CBX2 overexpression could reversed the reduction of cell proliferation or the enhancement of cell apoptosis induced by CASC9 suppression. CONCLUSIONS Our study manifests the first evidence that CASC9 serves as an oncogene in BC and accelerates cell proliferation by modulating miR-497-5p/CBX2 axis. The present study may provide a cogitable target for BC therapy.

Abstract
Bladder cancer (BC) is the ninth most common malignant disease and ranks fourteenth in cancer mortality worldwide. Moreover, among cancers, the incidence and mortality of BC in males increased to the 6th and 9th place, respectively. The overall survival (OS) declines dramatically as the cancer progresses, especially when urothelial cells transition from noninvasive to invasive. It is well known that epithelial cells can acquire invasive properties and a propensity to metastasize through the epithelial-to-mesenchymal transition (EMT) process in tumourigenesis and progression. However, the potential molecular mechanisms and key pathways are still unclear. As the sequencing technology advances, long non-coding RNAs (lncRNAs) have been proven to play an important role in regulating biological processes and cellular pathways. Here, we reviewed important lncRNAs, such as H19, UCA1 and MALAT1, that participate in the malignant phenotype of BC and regulate EMT signalling networks in the invasion-metastasis cascade during BC development. We further discuss MALAT1, PCAT-1 and SPRY4-IT1, and also urine and blood exosomal H19 and PTENP as potential noninvasive biomarkers. Moreover, antisense oligonucleotides (ASOs) and a double-stranded DNA plasmid (BC-819) have been designed for use in preclinical cancer models and clinical trials in patients. Therefore, the results of investigations have gradually prompted the utility of lncRNAs.

Abstract
Ovarian cancer (OC) is one of the most fatal types of gynecological malignancy. Certain long non-coding RNAs (lncRNA) have been reported to have crucial roles in cancer progression. Zinc finger nuclear transcription factor, X-box binding 1-type containing 1 antisense RNA 1 (ZFAS1) is a novel regulator lncRNA in various cancer types. The expression pattern of most lncRNAs, including ZFAS1, in OC remains to be determined. In the present study, it was demonstrated that ZFAS1 was overexpressed in OC vs. normal cell lines. However, ZFAS1 was downregulated in OC compared with normal samples in the GEPIA dataset. Furthermore, OC samples of higher stages (stage III/IV) had higher levels of ZFAS1 compared with those in early-stage OC (stage I/II) samples. Of note, higher ZFAS1 expression was associated with shorter overall survival time and disease-free survival time of OC patients. Protein-protein interaction networks of proteins co-expressed with ZFAS1 in OC were constructed. Furthermore, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis of genes co-expressed with ZFAS1 indicated that ZFAS1 is associated with translation, mRNA splicing, cell-cell adhesion, DNA repair, protein sumoylation, positive regulation of GTPase activity and DNA replication. The present study may provide novel clues to validate ZFAS1 as a biomarker in OC.

Abstract
Background Thyroid cancer is the most common endocrine malignancy, papillary thyroid carcinoma (PTC) is the main form of thyroid cancer. The long non-coding RNA (lncRNA) zinc finger antisense 1 (ZFAS1) is highly expressed in various cancer tissues and it has been shown to function as a tumor promoter in various cellular processes. However, the role of ZFAS1 in PTC is not well understood currently. Thus, this study aimed to explore the potential roles of ZFAS1 in the development and progression of PTC. Material and methods PTC tissues (n=80) and noncancerous tissues were collected. Gain- and loss-of-function assays were performed to determine the effect of ZFAS1 on proliferation in K-1 and TPC-1 cells. The ZFAS1/mir-590-3P/HMGA2 aixs were analysed in PTC cell lines. Results We found that the expression of ZFAS1 was increased in PTC tissues and four PTC cell lines (B-CPAP, IHH-4, TPC-1, and K-1). The gain- and loss-of-function assays showed that overexpressing ZFAS1 promoted cell proliferation and inhibited cell apoptosis in PTC cells in vitro. We demonstrated that knockdown of ZFAS1 inhibits tumor growth and upregulation of ZFAS1 promotes tumor growth in vivo. Bioinformatics analysis revealed that miR-590-3p targeted the 3ʹ-UTR of ZFAS1. The double luciferase reporter and RNA-binding protein immunoprecipitation assay demonstrated that miR-590-3p is a target of ZFAS1. Rescue experiments confirmed that miR-590-3p could reverse the effect of ZFAS1 on PTC cells. Moreover, we identified high mobility group AT-hook 2 (HMGA2) to be a downstream target of miR-590-3p and ZFAS1 which activates HMGA2 expression by sponging to miR-590-3p. Conclusion High ZFAS1 expression level was associated with the progression of PTC, and ZFAS1 contributed to PTC progression via miR-590-3p/HMGA2 regulatory aixs. Therefore, ZFAS1 might be a potential therapeutic target for PTC intervention.

Abstract
BACKGROUND Long non-coding RNA (lncRNA) zinc finger antisense 1 (ZFAS1) is a novel vital oncogenic lncRNA that is dysregulated in various types of cancers, including glioma. According to TargetScan prediction, miR-432-5p is a target of ZFAS1. Herein, we aimed to determine whether there was a correlation between ZFAS1 and miR-432-5p and to explore their roles in glioma. METHODS The expression levels of ZFAS1 and microRNA (miR)-432-5p in clinical tissues and cell lines were measured using RT-qPCR. Cell viability was detected using MTT assay. Cell apoptosis was examined using flow cytometry. The association between ZFAS1 and miR-432-5p was confirmed using luciferase reporter and RNA pull-down assays. RESULTS Zinc finger antisense 1 expression was up-regulated, while miR-432-5p expression was down-regulated in both glioma tissues and cells. Knockdown of ZFAS1 and miR-432-5p overexpression inhibited cell viability and enhanced the chemosensitivity of glioma cells to cisplatin. MiR-432-5p was a direct target of ZFAS1 in glioma cells. Inhibition of miR-432-5p blocked the effects of ZFAS1 knockdown on cell viability and cisplatin sensitivity. CONCLUSIONS Knockdown of ZFAS1 inhibited the viability and enhanced cisplatin sensitivity via targeting miR-432-5p in glioma cells.

Abstract
Background Colorectal cancer (CRC) is one of the most common tumors, the causes of which remain unclear. Recently, many kinds of long non-coding RNAs (lncRNAs) have been identified to have an important role in the biological function of CRC. However, the effect of lncRNA zinc finger antisense 1 (ZFAS1) on development of CRC is still incompletely clear. Material/Methods Firstly, the expression of ZFAS1 and microRNA (miR)-7-5p in 40 CRC tissues and adjacent tissues was measured by real-time polymerase chain reaction. Then, we detected the cell proliferation, migration, invasion, and apoptosis in CRC cell lines by using Cell Counting Kit-8 assay, colony formation assay, flow analysis, and Transwell assay, respectively. Then, the relationship between ZFAS1 and miR-7-5p was verified by luciferase reporter assay. Finally, rescue experiments were conducted to confirmed that interaction of ZFAS1 and miR-7-5p in vitro. Results Our results showed that ZFAS1 was upregulated in CRC tissues, correlated with overall survival rates, and negatively related to the expression of miR-7-5p. It was verified that miR-7-5p was a direct target of ZFAS1 by bioinformatics analysis and luciferase reporter assay. In addition, knockdown of miR-7-5p inhibited proliferation, migration, and invasion, and promoted apoptosis in CRC cell lines, which could be rescue by miR-7-5p inhibitor. Conclusions Our study indicated that ZFAS1 directly targeted miR-7-5p, and knockdown of it could inhibit tumor growth, migration, invasion, and induce apoptosis in CRC. These data might provide a potent treatment mechanism or promising biomarker for CRC.

Abstract
Cervical cancer holds one of the highest morbidity and mortality in various types of cancers. It even leads to the most number of cancer-related deaths of women. A lot of research has indicated that the anomalous expression of long noncoding RNAs (lncRNAs) would induce carcinogenesis and is associated with poor prognosis of patients with cancer. However, the function and mechanism of many lncRNAs still call for further research. Tumor Protein P73 Antisense RNA 1 (TP73-AS1) is no exception. LncRNA TP73-AS1 has been found to promote cancer progressions in various cancers. It is upregulated in cervical cancer cells. The proliferation and migration ability of cervical cancer cells can also be boosted by TP73-AS1 in return. Meanwhile, miRNA-329-3p is downregulated in cervical cancer cells and could bind with both TP73-AS1 and ADP Ribosylation Factor 1 (ARF1). TP73-AS1 inhibited miR-329-3p expression while miR-329-3p inhibited ARF1 expression. More importantly, TP73-AS1 can positively regulate ARF1 expression. Based on all these experiments, TP73-AS1 regulates ARF1 expression by competitively binding with miR-329-3p, thus regulating cervical cancer progression. Further rescue assays confirmed TP73-AS1 regulates cervical cell proliferation and migration via miR-329-3p/ARF1. TP73-AS1 might serve as a novel regulator in cervical cancer.

Abstract
Pre-eclampsia (PE) is a pregnancy disease that causes maternal death and threatens the health of newborns. Accumulating evidence has revealed the essential roles of long noncoding RNAs (lncRNAs) in the progression of PE. The present investigation determined lncRNA ZEB2 antisense RNA 1 (ZEB2-AS1) expression in PE and looked into the potential role of ZEB2-AS1 in modulating trophoblastic cell functions. Quantitative real-time polymerase chain reaction evaluated gene expression. Western blot analyzed the placental growth factor (PGF) protein level. Cell counting kit-8 and Transwell invasion assays assessed the proliferative and invasive abilities of placental trophoblast cells, respectively. Wound healing assay determined cell migratory potentials. Dual-luciferase reporter assay assessed the targeting relationship among ZEB2-AS1, miR-149, and PGF. Downregulation of lncRNA ZEB2-AS1 was detected in placentas from patients with PE when compared with those from normal pregnancies. Moreover, ZEB2-AS1 upregulation markedly promoted proliferative, migratory, and invasive potentials in HTR-8/SVneo cells, while knockdown of ZEB2-AS1 had the opposite effects. The effects on HTR-8/SVneo cells mediated by ZEB2-AS1 was correlated with the miR-149/PGF axis. These findings indicate that ZEB2-AS1 contributes to PE progression by affecting cell proliferative and invasive capacities via the miR-149/PGF axis in HTR-8/SVneo cells. In sum, we identified that ZEB2-AS1 was a novel aberrantly expressed lncRNA in the placentas of PE patients and lncRNA ZEB2-AS1 modulated trophoblastic cell line HTR-8/SVneo's proliferative and invasive potentials via targeting the miR-149/PGF axis.

Abstract
Background Thyroid cancer is a type of endocrine cancers with rapidly increased incidence. Recent studies have indicated long non-coding RNAs (lncRNAs) played crucial roles in thyroid cancer tumorigenesis and progression. However, the roles of most lncRNAs in thyroid cancer were still unclear. Material/Methods We used TCGA (The Cancer Genome Atlas), GSE50901, GSE29265, and GSE33630 datasets to analyze the expression pattern of ZFAS1 (ZNFX1 antisense RNA 1). The correlation between ZFAS1 and clinicopathological features in thyroid cancer was analyzed. Cell proliferation and cell cycle assays were used to validate the roles of ZFAS1 in thyroid cancer cell lines. DAVID (the database for annotation, visualization and integrated discover) system was used to perform GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway analysis. The starBase datasets and Cytoscape was used to perform ceRNA (competitive endogenous RNA) network. Results We demonstrated ZFAS1 was highly expressed in thyroid cancer compared to normal samples. Moreover, upregulation of ZFAS1 was positively correlated with clinicopathological features and poor prognosis in thyroid cancer. Functional validation showed knockdown of ZFAS1 suppressed cell proliferation and cell cycle in thyroid cancer cells. Bioinformatics analysis showed ZFAS1 was associated with translation, rRNA processing, intra-Golgi vesicle-mediated transport, ribosome, and ubiquitin-mediated proteolysis. Conclusions Our study suggested ZFAS1 could serve as a biomarker for thyroid cancer.

Abstract
Non-small-cell carcinoma (NSCLC) is the most common cancer along with high mortality rate worldwide. In the present study, our data showed that lncRNA MAF BZIP Transcription Factor G Antisense RNA 1 (MAFG-AS1) was over-expressed in NSCLC tissues and cell lines. Overexpression of MAFG-AS1 promoted the migration, invasion and enhanced epithelial-mesenchymal transition (EMT) of NSCLC cell. In addition, miR-339-5p was predicted to be a target of MAFG-AS1 and the level of miR-339-5p was down-regulated in NSCLC. Over-expression of MAFG-AS1 significantly decreased the level of miR-339-5p in NSCLC cell. Moreover, the matrix metalloproteinase 15 (MMP15) was identified to be a target of miR-339-5p. The level of MMP15 was negatively regulated by miR-339-5p whereas positively controlled by MAFG-AS1. In addition, up-regulation of miR-339-5p neutralized the promoting impact of MAFG-AS1 on the migration, invasion and EMT of NSCLC cell. Finally, the xenograft model suggested that MAFG-AS1 promoted the metastasis of NSCLC cell in vivo. Altogether, we proved that MAFG-AS1-miR-339-5p-MMP15 axis might be a promising therapeutic target for the treatment of patients with NSCLC.

Abstract
Zinc finger antisense 1 (ZFAS1), a newly identified long non-coding RNA, is a transcript antisense to the 5' end of the protein-coding gene zinc finger NFX1-type containing 1 which hosts three C/D-box small nucleolar RNAs (SNORDs) within sequential introns: Snord12, Snord12b, and Snord12c. ZFAS1 is dysregulated and acts as either an oncogene or a tumor suppressor in different human malignancies. ZFAS1 has been implicated in many aspects of carcinogenesis, including proliferation, invasion, metastasis, apoptosis, cell cycle, and drug resistance. The mechanisms underlying the effects of ZFAS1 are complex and involve multiple signaling pathways. In this review, the multiple pathological functions of ZFAS1 in diverse malignancies are systematically reviewed to elucidate the molecular basis of its biological roles and to provide new directions for future research.

Abstract
As a new group of important effector molecules involved in multiple cancers, long noncoding RNAs (lncRNAs) have attracted much attention recently. Especially, evidences have indicated lncRNAs might be promising biomarkers and targets for cancer therapy. LINC00641 is a novel lncRNA, whose function remains totally unclear. The aim of our study was to determine the functions of LINC00641 in bladder cancer. We found that LINC00641 expression was significantly down-regulated in bladder cancer tissues. Down-regulation of LINC00641 in patients with bladder cancer predicts poor prognosis. Gain-of-function assays indicated that LINC00641 up-regulation markedly inhibited the proliferation, migration and invasion of bladder cancer cells. Xenograft assay also confirmed that LINC00641 overexpression suppressed bladder cancer growth in vivo. Mechanistically, LINC00641 was demonstrated to interact with miR-197-3p, whose target was KLF10. By up-regulating KLF10 level, LINC00641 suppressed the PTEN/PI3K/AKT pathway, leading to prevention of bladder cancer progression. Taken together, our study illustrated a novel signaling cascade of LINC00641/miR-197-3p/KLF10/PTEN/PI3K/AKT pathway regulating bladder cancer development.
