Cancer Med 2023; 12:8351-8366. [PMID: 36708020 PMCID: PMC10134332 DOI: 10.1002/cam4.5550] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Revised: 12/03/2022] [Accepted: 12/08/2022] [Indexed: 01/29/2023] Open
Abstract
BACKGROUND Colorectal cancer (CRC) is a disease with high morbidity and mortality rates globally. Long noncoding RNAs (lncRNAs) play a fundamental role in tumor progression, and increasing attention has been paid to their role in CRC. This study aimed to determine the function of lncRNA DICER1 antisense RNA 1 (DICER1-AS1) in CRC and confirm its potential regulatory mechanisms in CRC. METHODS The publicly available dataset was used to assess DICER1-AS1 function and expression in CRC. RT-qPCR or western blot assays were performed to verify DICER1-AS1, miR-650, and mitogen-activated protein kinase 1 (MAPK1) expression in CRC cells or tissues. To determine the function of DICER1-AS1, we performed CCK-8, colony formation, transwell, cell cycle, and in vivo animal assays. Using RNA sequence analysis, luciferase reporter assays, and bioinformatics analysis, the connection between DICER1-AS1, MAPK1, and miR-650 was investigated. RESULTS DICER1-AS1 was significantly upregulated in CRC tissue compared to normal colon tissue. High DICER1-AS1 expression suggested a poor prognosis in CRC patients. Functionally, upregulation of DICER1-AS1 effectively promoted CRC proliferation, migration, and invasion ex vivo and tumor progression in vivo. Mechanistically, DICER1-AS1 functions as a competitive endogenous RNA (ceRNA) that sponges miR-650 to upregulate MAPK1, promotes ERK1/2 phosphorylation, and sequentially activates the MAPK/ERK signaling pathway. CONCLUSION Our investigations found that upregulation of DICER1-AS1 activates the MAPK/ERK signaling pathway by sponging miR-650 to promote CRC progression, revealing a possible clinically significant biomarker and therapeutic target.

UFMylation System: An Emerging Player in Tumorigenesis. Cancers (Basel) 2022; 14:cancers14143501. [PMID: 35884562 PMCID: PMC9323365 DOI: 10.3390/cancers14143501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 07/08/2022] [Accepted: 07/16/2022] [Indexed: 11/16/2022] Open
Abstract
Simple Summary The ubiquitin-fold modifier 1 (UFM1) is a newly identified post-translational modification protein that has been implicated in multiple cellular processes and diseases. Noticeably, an aberrant UFM1 modification system has been closely related to various types of tumorigeneses, implying that the restoration of UFMylation homeostasis may serve as a promising therapeutic strategy. In this review, we summarize the structure, process and biological functions of the UFM1 modification system. In particular, we discuss the relationship between the UFMylation system and tumorigenesis, illustrating the underlying mechanisms and future perspectives. This article aims to improve our understanding of UFM1 modification, as well as provide some new strategies for cancer treatment. Abstract Ubiquitin-fold modifier 1 (UFM1), a newly identified ubiquitin-like molecule (UBLs), is evolutionarily expressed in multiple species except yeast. Similarly to ubiquitin, UFM1 is covalently attached to its substrates through a well-orchestrated three-step enzymatic reaction involving E1, the UFM1-activating enzyme (ubiquitin-like modifier-activating enzyme 5, UBA5); E2, the UFM1-conjugating enzyme 1 (UFC1); and E3, the UFM1-specific ligase 1 (UFL1). To date, numerous studies have shown that UFM1 modification is implicated in various cellular processes, including endoplasmic reticulum (ER) stress, DNA damage response and erythroid development. An abnormal UFM1 cascade is closely related to a variety of diseases, especially tumors. Herein, we summarize the process and functions of UFM1 modification, illustrating the relationship and mechanisms between aberrant UFMylation and diversified tumors, aiming to provide novel diagnostic biomarkers or therapeutic targets for cancer treatments.

Silencing of Long Noncoding RNA HLA Complex P5 (HCP5) Suppresses Glioma Progression through the HCP5-miR-205-Vascular Endothelial Growth Factor A Feedback Loop. BIOMED RESEARCH INTERNATIONAL 2022; 2022:3092063.

Abstract
Long noncoding RNA (lncRNA) HLA complex P5 (HCP5) is correlated with multiple diseases, especially cancers. However, it remains to be further studied whether HCP5 is involved in the malignant behaviors of gliomas. This study is aimed at investigating the role and regulation mechanisms of HCP5 in gliomas. HCP5 expression in glioma tumor tissues and its association with glioma patients' survival were analyzed based on RNA-sequencing data. The expression of HCP5 was also examined in glioma cells. Then, HCP5 was downregulated in U251 cells and/or primary glioblastoma cells to explore its effects on cell proliferation and migration. The influence of HCP5 downregulation on tumor growth was confirmed in xenograft mice. About the mechanism, we investigated whether HCP5 functioned via interacting with microRNA- (miR-) 205 and regulating vascular endothelial growth factor A (VEGF-A) expression in gliomas. Results showed that HCP5 upregulation was found in glioma tissues and cell lines. Patients with high HCP5 expression showed lower survival probability and shorter survival time. HCP5 downregulation inhibited cell proliferation and migration and mitigated tumor growth. miR-205 was downregulated in glioma cells. Knockdown of HCP5 led to miR-205 upregulation and VEGF-A downregulation. miR-205 overexpression exhibited the similar effects as HCP5 downregulation on cell viability and proliferation. And VEGF-A overexpression could reverse the effects of HCP5 downregulation on cell viability and proliferation, as well as tumor growth. In conclusion, HCP5 silencing suppressed glioma progression through the HCP5-miR-205-VEGF-A feedback loop.

Association between long noncoding RNA rs944289 and rs7990916 polymorphisms and the risk of colorectal cancer in a Chinese population. Sci Rep 2022; 12:2495. [PMID: 35169218 PMCID: PMC8847648 DOI: 10.1038/s41598-022-06474-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 01/28/2022] [Indexed: 12/24/2022] Open
Abstract
Long non-coding RNAs (LncRNAs) play vital roles in the tumorigenesis of many cancers. Single nucleotide polymorphisms (SNPs) of the lncRNA also play vital roles in tumorigenesis. We explored lncRNA rs944289 and rs7990916 polymorphisms and analyzed the relationship between these lncRNA polymorphisms with the colorectal cancer (CRC) risk in a Chinese population. We recruited 1003 CRC patients from the Affiliated People’s Hospital of Jiangsu University and the Fujian Medical University Union Hospital from October 2014 to August 2017. Genomic DNA was extracted using a DNA Kit from lymphocytes of peripheral blood and the genotyping was performed with a SNPscan method. We found that the rs944289 TT homozygote was associated with the decreased CRC risk in the overall population. LncRNA rs944289 TT decreased the CRC risk in the subgroup of female, male, age ≥ 61, without alcohol intake, smoking and BMI ≥ 24 by logistic regression. The subgroup analysis revealed that lncRNA rs7990916 was not associated with CRC risk except for age < 61. Logistic regression analysis revealed that lncRNA rs944289 TT homozygote was associated with the increased risk of rectum cancer (TT vs. CC + CT: adjusted OR = 1.29, 95% CI 1.10–1.66, P = 0.041) or colon cancer. In summary, we proved that lncRNA rs944289 might be significantly related to the decreased CRC risk in the Chinese Han populations and lncRNA rs7990916 was not associated with the CRC risk except for patients of age < 61. In the future, studies with larger samples should be conducted to validate our results.

Abstract
Recent accumulating researches implicate that non-coding RNAs (ncRNAs) including microRNA (miRNA), circular RNA (circRNA), and long non-coding RNA (lncRNAs) play crucial roles in colorectal cancer (CRC) initiation and development. Notably, N6-methyladenosine (m6A) methylation, the critical posttranscriptional modulators, exerts various functions in ncRNA metabolism such as stability and degradation. However, the interaction regulation network among ncRNAs and the interplay with m6A-related regulators has not been well documented, particularly in CRC. Here, we summarize the interaction networks and sub-networks of ncRNAs in CRC based on a data-driven approach from the publications (IF > 6) in the last quinquennium (2016–2021). Further, we extend the regulatory pattern between the core m6A regulators and m6A-related ncRNAs in the context of CRC metastasis and progression. Thus, our review will highlight the clinical potential of ncRNAs and m6A modifiers as promising biomarkers and therapeutic targets for improving the diagnostic precision and treatment of CRC.

Abstract
Post-translational modification with Ubiquitin-like proteins represents a complex signaling language regulating virtually every cellular process. Among these post-translational modifiers is Ubiquitin-fold modifier (UFM1), which is covalently attached to its substrates through the orchestrated action of a dedicated enzymatic cascade. Originally identified to be involved embryonic development, its biological function remains enigmatic. Recent research reveals that UFM1 regulates a variety of cellular events ranging from DNA repair to autophagy and ER stress response implicating its involvement in a variety of diseases. Given the contribution of UFM1 to numerous pathologies, the enzymes of the UFM1 cascade represent attractive targets for pharmacological inhibition. Here we discuss the current understanding of this cryptic post-translational modification especially its contribution to disease as well as expand on the unmet needs of developing chemical and biochemical tools to dissect its role.

Abstract
BACKGROUND AND AIM Long noncoding RNA TRPM2-AS has emerged as a novel regulator in cancer initiation and progression of various cancers. However, the function and underlying mechanism of TRPM2-AS in the progression of gastric cancer (GC) remain poorly understood. METHODS GEO and TCGA databases were used for isolation of differential lncRNA expression. TRPM2-AS expression levels in GC tissues and cells were measured by quantitative polymerase chain reaction method. TRPM2-AS subcellular location was detected by fluorescence in situ hybridization analysis. The functional roles of TRPM2-AS in cells were analyzed by loss and gain function assays. RESULTS By using bioinformatics and quantitative polymerase chain reaction methods, TRPM2-AS expression levels were proved to be upregulated in GSE70880 dataset, TCGA database, and 26 GC tissues, which was partly induced by SP1. The results of clinical assays showed that TRPM2-AS could be an indicator for early-stage GC diagnosis. Fluorescence in situ hybridization analysis showed that TRPM2-AS was located in both nucleus and cytoplasm. Functional experiments displayed that knockdown of TRPM2-AS inhibited proliferation, migration, and invasion in GC cells. Furthermore, depression of TRPM2-AS suppressed cell growth though promotion of cell apoptosis. The expression levels of cleaved PARP, caspase 9, caspase 3, and Bax were significantly increased in BGC823 with TRPM2-AS knockdown. In addition, knockdown of TRPM2-AS reduced and phosphorylate signal transducer and activator of transcription 3 and increased and phosphorylate p38 mitogen-activated protein kinase. CONCLUSIONS This study demonstrated that SP1-regulated TRPM2-AS is involved in GC cell apoptosis probably via p38 mitogen-activated protein kinase and signal transducer and activator of transcription 3 pathways, indicating that TRPM2-AS might be a potential therapeutic target in GC.

Abstract
Long intergenic noncoding RNAs (lincRNAs) play a vital role in the occurrence and progression of cancer. The mechanism of lincRNAs in colorectal cancer (CRC) has not been fully elucidated. In this context, an integrated comparative long noncoding RNA (lncRNA) microarray technology was used to determine the expression profile of lncRNAs in CRC. The roles of LINC00908 are unclear. We found that LINC00908 was significantly upregulated in CRC. Inhibition of LINC00908 resulted in reduced cell proliferation and G1 cell cycle arrest, which was mediated by cyclin D1, cyclin-dependent kinase 4, and phosphorylated retinoblastoma. Moreover, inhibition of LINC00908-induced apoptosis through the intrinsic apoptosis signaling pathway, as shown by the activation of caspase-9 and caspase-3. Mechanistically, miR-143-3p directly bound to LINC00908. miR-143-3p expression was negatively correlated with LINC00908 expression in CRC tissue. Functional experiments revealed opposing roles for miR-143-3p and LINC00908, suggesting that LINC00908 negatively regulates miR-143-3p. Mechanistically, miR-143-3p directly targets LINC00908. The KLF5 inhibitor ML264 affected proliferation and apoptosis, indicating that LINC00908 may act as a competing endogenous RNA to facilitate the expression of the miR-143-3p target gene KLF5. Thus, LINC00908 has an important proliferative and antiapoptotic role in CRC by regulating the cell cycle and intrinsic apoptosis. LINC00908 could be a potential biomarker and a new therapeutic target for CRC.

Abstract
Long non-coding RNAs (LncRNAs) have been suggested as important regulators of cancer development and progression in non-small cell lung cancer (NSCLC). Nevertheless, the biological roles and clinical significance of lncRNA UFC1 in NSCLC remain unclear. We detected the expression of UFC1 in tumor tissues, serum, and serum exosomes of NSCLC patients by qRT-PCR. Gene overexpression or silencing were used to examine the biological roles of UFC1 in NSCLC. RNA immunoprecipitation and ChIP assays were performed to evaluate the interaction between UFC1 and enhancer of zeste homolog 2 (EZH2) and the binding of EZH2 to PTEN gene promoter. Rescue study was used to access the importance of PTEN regulation by UFC1 in NSCLC progression. UFC1 expression was upregulated in tumor tissues, serum, and serum exosomes of NSCLC patients and high level of UFC1 was associated with tumor infiltration. UFC1 knockdown inhibited NSCLC cell proliferation, migration and invasion while promoted cell cycle arrest and apoptosis. UFC1 overexpression led to the opposite effects. Mechanistically, UFC1 bound to EZH2 and mediated its accumulation at the promoter region of PTEN gene, resulting in the trimethylation of H3K27 and the inhibition of PTEN expression. UFC1 knockdown inhibited NSCLC growth in mouse xenograft tumor models while the simultaneous depletion of PTEN reversed this effect. NSCLC cells derived exosomes could promote NSCLC cell proliferation, migration and invasion through the transfer of UFC1. Moreover, Exosome-transmitted UFC1 promotes NSCLC progression by inhibiting PTEN expression via EZH2-mediated epigenetic silencing. Exosome-mediated transmit of UFC1 may represent a new mechanism for NSCLC progression and provide a potential marker for NSCLC diagnosis.

Wei Y, Wang Z, Zong Y, Deng D, Chen P, Lu J. LncRNA MFI2-AS1 promotes HCC progression and metastasis by acting as a competing endogenous RNA of miR-134 to upregulate FOXM1 expression. Biomed Pharmacother 2020; 125:109890. [PMID: 32106369 DOI: 10.1016/j.biopha.2020.109890] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 12/19/2019] [Accepted: 12/26/2019] [Indexed: 01/17/2023] Open
Abstract
Hepatocellular carcinoma (HCC) is worldwide accepted most common malignancies, as well as the second major cause of death among Chinese with cancer. There is an increasing evidence that could prove the potential effect of long non-coding RNAs (lncRNAs) to the biological performance of HCC. In present study, with high expression level in The Cancer Genome Atlas (TCGA) HCC samples, lncRNA MFI2 Antisense RNA 1 (MFI2-AS1) was closely related to poor prognosis and advanced stage among patients with HCC. In addition, up-regulation of MFI2-AS1 was further comfirmed in HCC tissues and HCC cell line. Ectopic expression of MFI2-AS1 stimulated the proliferation and metastasis of HCC cells, but knockdown MFI2-AS1 suppressed HCC cell proliferation and metastasis, indicating that MFI2-AS1 exerted oncogenic functions in the tumorigenesis of HCC. Simultaneously, compared with the negative control group, xenograft tumors in MFI2-AS1 group were characterized with poor growth, smaller volumes and less liver metastases. The post-transcriptional regulation of FOXM1 by MFI2-AS1 occured mechanistically, playing a role of competing with endogenous RNA (ceRNA) in HCC to sponge miR-134. Over-expression of MFI2-AS1 increased FOXM1 expression both at mRNA and protein level, whereas it was reducd by miR-134. Meanwhile, knockdown of miR-134 abolished the repression of shMFI2-AS1 on FOXM1 expression. Furthermore, we demonstrated that miR-134 reverses the impact of MFI2-AS1 on HCC proliferation and metastasis through regulation on FOXM1. Collectively, we determined that MFI2-AS1 crucially acted in HCC progression via functioning as miR-134 sponge to upregulating FOXM1 expression, and was conducive to the promotion of better understanding the direct diagnostics and iatreusiology of lncRNA in HCC.

Int J Mol Med 2020; 45:1250-1260. [PMID: 32124944 DOI: 10.3892/ijmm.2020.4492] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Accepted: 01/08/2020] [Indexed: 11/05/2022] Open
Abstract
The problems caused by diabetes mellitus (DM) and its related complications are gaining increasing attention. In our previous study, the abnormal proliferation of small intestinal epithelial cells (IECs) were observed in diabetic mice. However, little is known regarding the potential underlying mechanism. In the present study, the abnormal proliferation of IECs in DM and the marked upregulation of metastasis associated lung adenocarcinoma transcript 1 (MALAT1) was observed. Additionally, knockdown of MALAT1 significantly reduced abnormal IESC proliferation in DM mice. Bioinformatics analysis and luciferase reporter assays revealed that microRNA (miR)‑129‑5p was directly targeted by MALAT1. Moreover, the results of the bioinformatics prediction and luciferase assays demonstrated that MALAT1 directly interacted with SRY‑box 9 (SOX9). Furthermore, MALAT1 silencing was observed to attenuate the abnormal proliferation of IESCs through the SOX9‑mediated WNT/β‑catenin signaling pathway. Knockdown of MALAT1 downregulated SOX9 expression by binding to miR‑129‑5p, thereby inhibiting the abnormal proliferation of IESCs via the WNT/β‑catenin signaling pathway.

Abstract
Early diagnosis is important to improve the prognosis of pancreatic cancer (PC). Identifying potential biomarkers is essential for the monitoring and treatment of PC. The long noncoding RNA (lncRNA) UFC1 has been identified as an oncogenic factor in many cancers. However, the expression of UFC1 and its potential role in diagnosis and prognosis of PC remain largely unknown. The present study aimed to investigate the role of serum UFC1 in diagnosis and prognosis. The results indicated that serum UFC1 expression was relatively higher in PC patients than that in healthy volunteers. ROC curve analysis revealed that the serum UFC1 levels could distinguish PC patients from healthy controls, with an AUC value of 0.810. In addition, the serum UFC1 expression level was associated with lymph nodes metastasis, distant metastasis, and clinical stage. Kaplan-Meier analysis indicated that patients with high UFC1 expression exhibited shorter progression-free survival (PFS) and overall survival (OS) than those with low UFC1 expression. Multivariate analysis demonstrated that clinical stage and UFC1 expression level were significant, independent prognostic factors in PC patients. Our data demonstrate that serum UFC1 might serve as a potential biomarker for diagnosis and prognosis of PC.

Abstract
Background At present, a number of long non-coding RNAs (lncRNAs) have been realized as the critical regulators of breast cancers. Current evidence indicates that dysregulation of UFC1 contributes to the tumorigenesis and progression of various types of human cancer. However, the roles of UFC1 in breast cancer are still unclear. Material/Methods Firstly, we measured the expression of UFC1 in breast cancer tissues and cells lines compared with corresponding controls. Then, cell functional assays were performed to determine the roles of UFC1 in breast cancer progression in vitro. Moreover, the correlation between UFC1 and miR-34a was determined by luciferase reporter assays. Further, the role of miR-34a in regulating biological function of breast cancer and its downstream target CXCL10 was applied by a series of functional assays. Results In present study, we found that UFC1 was highly expressed in breast tissue and cells lines compared with normal tissues and cell lines. Silenced UFC1 suppressed multiple biological activities of breast cancer cells, which also functioned as a miR-34a sponge in breast cancer. Furthermore, over-expressing miR-34a could prominently suppress cell growth, invasion, migration and inducing apoptosis in breast cancer cells. In addition, we verified that miR-34a was a target of CXCL10 by bioinformatics analysis and luciferase reporter assay. Conclusions LncRNA UFC1 regulated biological activity of breast cancer via miR-34a/CXCL10 axis, providing a novel diagnosis biomarker and potential therapeutic target for breast cancer.

Abstract
Colorectal cancer (CRC) is one of the most prevalent digestive tumors in China. Recent studies indicate that long intergenic non-coding RNAs (lincRNAs) play a crucial role in predicting survival for CRC patients. However, the novel lincRNA, LINC00957, is largely unclear in CRC. The purpose of the current study was to determine LINC00957 expression, assess its the clinical significance and explore the potential mechanism in CRC. The qRT-PCR was used to quantify the expression levels of LINC00957 in tissues and cell lines. Our research revealed that LINC00957 was significantly higher expression in CRC. In addition, the LINC00957 expression was associated with TNM stage and chemotherapy outcome, but age, gender, tumor size, histological grade, primary tumor location. CRC patients with high LINC00957 expression level showed poor overall survival (P = 0.002). Multivariate survival analysis indicated that LINC00957 was a prognostic factor for CRC patients (P = 0.010). Mechanically, inhibition of LINC00957 expression reversed 5-FU resistance by down-regulating P-gP. In summary, our study indicated that this novel lncRNA expression signature might be a useful biomarker of the prognosis and therapeutic target for CRC patients.

Abstract
Shiga toxin-producing Escherichia coli (STEC) O113:H21 strains are associated with human diarrhea and some strains may cause hemolytic-uremic syndrome (HUS). In Brazil, these strains are commonly found in cattle but, so far, were not isolated from HUS patients. Here, a system biology approach was used to investigate the differential transcriptomic and phenotypic responses of enterocyte-like Caco-2 cells to two STEC O113:H21 strains with similar virulence factor profiles (i.e. expressing stx2, ehxA, epeA, espA, iha, saa, sab, and subA): EH41 (Caco-2/EH41), isolated from a HUS patient in Australia, and Ec472/01 (Caco-2/Ec472), isolated from bovine feces in Brazil, during a 3 h period of bacteria-enterocyte interaction. Gene co-expression network analysis for Caco-2/EH41 revealed a quite abrupt pattern of topological variation along 3 h of enterocyte-bacteria interaction when compared with networks obtained for Caco-2/Ec472. Transcriptional module characterization revealed that EH41 induces inflammatory and apoptotic responses in Caco-2 cells just after the first hour of enterocyte-bacteria interaction, whereas the response to Ec472/01 is associated with cytoskeleton organization at the first hour, followed by the expression of immune response modulators. Scanning electron microscopy showed more intense microvilli destruction in Caco-2 cells exposed to EH41 when compared to those exposed to Ec472/01. Altogether, these results show that EH41 expresses virulence genes, inducing a distinctive host cell response, and is likely associated with severe pathogenicity.

Abstract
OBJECTIVE To explore the role of Long noncoding RNA UFC1 (lincRNA-UFC1) in modulating the metastasis and invasion of hepatocellular carcinoma (HCC) cells and the underlying mechanism. METHODS Human HCC cell line Huh7 was infected with the lentiviral vector carrying lincRNA-UFC1 to obtain a cell line with lincRNA-UFC1 overexpression. A short hairpin RNA (shRNA) targeting lincRNA-UFC1 was delivered in human HCC BEL-7402 cells via a lentiviral vector to obtain a cell line with lincRNA-UFC1 knockdown. Expression levels of lincRNA-UFC1 in the two HCC cell lines were detected using real-time PCR, and the changes in the cell invasion and migration in response to lincRNA-UFC1 overexpression or knockdown were analyzed using Transwell and wound-healing assays. The expressions of GSK-3β/β-catenin-related proteins in the cells were detected with Western blotting. XAV-939, a GSK-3β/β-catenin inhibitor, was used for assessing the impact of lincRNAUFC1 overexpression on the invasion and migration of the HCC cells through Transwell and wound-healing assays. RESULTS Overexpression of lincRNA-UFC1 significantly promoted the invasion and migration of Huh7 cells as compared with the control cells (P < 0.001), while lincRNA-UFC1 knockdown obviously suppressed the invasion and migration of BEL-7402 cells (P < 0.001). The results of Western blotting showed that the expressions of proteins associated with the cell invasion and migration, namely β-catenin and P-GSK-3β, were significantly upregulated in response to lincRNA-UFC1 overexpression, and were obviously lowered after lincRNA-UFC1 knockdown. Treatment of the cells with XAV-939 significantly reversed the effect of lincRNA-UFC1 overexpression on the cell invasion and migration (P < 0.001). CONCLUSIONS lincRNA-UFC1 overexpresison promotes cell invasion and migration through the GSK-3β/β-catenin axis in HCC cells in vitro.

Abstract
Long noncoding RNAs (lncRNAs) are important regulators of the biological functions and underlying molecular mechanisms of colorectal cancer (CRC). However, the role of the lncRNA ZEB1-AS1 in CRC is not thoroughly understood. In this study, we found that ZEB1-AS1 was markedly upregulated in CRC. ZEB1-AS1 knockdown significantly suppressed CRC cell proliferation and induced apoptosis, whereas enhanced expression of ZEB1-AS1 had the opposite effect. Bioinformatics analysis identified miR-181a-5p as a candidate target of ZEB1-AS1. Moreover, we found an inverse correlation between ZEB1-AS1 and miR-181a-5p expression in CRC tissue. Inhibition of miR-181a-5p significantly upregulated ZEB1-AS1, whereas overexpression of miR-181a-5p had the opposite effect, suggesting that ZEB1-AS1 is negatively regulated by miR-181a-5p. Using luciferase reporter and RIP assays, we found that miR-181a-5p directly targets ZEB1-AS1. Importantly, ZEB1-AS1 may act as an endogenous 'sponge' to regulate miRNA targets by competing for miR-181a-5p binding. In summary, our findings provide the evidence supporting the role of ZEB1-AS1 as an oncogene in CRC. Our study also demonstrates that miR-181a-5p targets not only protein-coding genes but also the lncRNA ZEB1-AS1.

Abstract
BACKGROUND Long non-coding RNAs (lncRNAs) have emerged as important regulators of human cancers. However, the functional roles of lncRNAs and the mechanisms responsible for their aberrant expression in gastric cancer (GC) have not been well characterized. METHODS In this study, we examined the expression of lncRNA UFC1 in GC by qRT-PCR and explored its correlation with clinicopathological parameters. In vitro cell functional assays and in vivo animal studies were performed to determine the roles of UFC1 in GC progression. RESULTS UFC1 was elevated and predicted poorer prognosis in GC. UFC1 knockdown inhibited while UFC1 overexpression promoted GC cell proliferation, migration, and invasion. UFC1 bound to miR-498 to antagonize its tumor suppressive effect on Lin28b. Suppression of Lin28b by miR-498 could be rescued by UFC1 overexpression, whereas Lin28b overexpression partially rescued UFC1 knockdown-mediated inhibition of GC cell function. Lin28b expression was increased in GC and suggested a co-expression pattern with UFC1. CONCLUSIONS UFC1 has a promoting role in GC progression, at least in part, by acting as a miR-498 sponge and derepressing Lin28b expression, which would provide a novel biomarker for GC diagnosis and prognosis and offer a potential target for GC therapy.

Abstract
Cervical cancer is one of the most common gynecologic cancers around the world. Long noncoding RNAs (lncRNAs) are considered to be important regulators of some biological processes. Recently, it has been reported that linc‐UFC1 is a putative oncogene in some cancers. However, the functional roles of linc‐UFC1 have not been investigated in cervical cancer. Here, it was demonstrated that linc‐UFC1 expression was significantly increased in cervical cancer tissues, and its overexpression was associated with the poor survival of patients with cervical cancer. Loss‐of‐function assays indicated that linc‐UFC1 exerted as an oncogene because it promoted the growth and metastasis of cervical cancer cells in vitro and in vivo. Mechanistic investigations revealed that linc‐UFC1 upregulated FOXP3 expression through competitively binding miR‐34a. Finally, luciferase reporter and chromatin immunoprecipitation (ChIP) assays provided evidence that E2F1 could directly bind to the linc‐UFC1 promoter region and enhance its transcription. Taken together, our findings indicate that the linc‐UFC1 expression signature may serve as a novel biomarker for the diagnosis and prognosis of cervical cancer, and it is also highlighted that the E2F1‐linc‐UFC1/miR‐34a/FOXP3 axis may be a potentially therapeutic target of cervical cancer.

Abstract
It is reported that long noncoding RNAs (lncRNAs) were expressed aberrantly in cartilage of osteoarthritis (OA). Current evidence indicates that lncRNAs not only serve as positive or negative regulators of OA, but also crosstalk with multiple potential targets to impact on the critical events in OA process. This review summarized the lncRNAs identified in OA to date, discussed their influence on the survival of chondrocytes and synoviocytes, arthritis-associated factors, and angiogenesis, and indicated the potential in diagnosis, therapy, and prognosis.

Abstract
Osteoarthritis (OA) is one of the most common prevalent chronic joint diseases. Emerging pieces of evidence have demonstrated that chondrocytes survival was closely associated with the destruction of joints in OA patients. Long noncoding RNAs (lncRNAs), defined as >200 nucleotides in length, also have been implicated in a variety of disease states. However, there are few studies on the role of lncRNAs in OA, and the pathological contributions of lncRNAs to OA remain largely unknown. In this study, we examined the expression of lncRNA UFC1 in cartilage samples from OA patients and healthy subjects, and then investigated biological function of UFC1 in OA chondrocyte. We found that the UFC1 was significantly reduced in OA patients. Functional assays demonstrated that UFC1 promotes chondrocytes proliferation and inhibits cell apoptosis. Furthermore, we found that UFC1 regulates survival of OA chondrocytes through physically association with miR-34a. Taken together, our data highlight the important roles of lncRNA UFC1 in the survival of OA chondrocytes. UFC1 may be a potential therapy for OA.
