Differential expression of long non-coding RNAs in colon cancer: Insights from transcriptomic analysis. Pathol Res Pract 2024; 261:155477. [PMID: 39067175 DOI: 10.1016/j.prp.2024.155477] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2024] [Revised: 06/11/2024] [Accepted: 07/16/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND Colon Cancer (CC) incidence has sharply grown in recent years. Long non-coding RNAs (lncRNA) are produced by a group of non-protein-coding genes, and have important functions in controlling gene expression and impacting the biological features of various malignancies including CC. METHODS Our research focused on examining the function of lncRNAs in the development of colon cancer. To this end, we selected and analyzed a dataset (GSE104836) from the GEO database, which contained information about the expression of mRNAs and lncRNAs in both colon cancer tissues and normal adjacent paired tumor tissues. The DESeq2 R package in Bioconductor was used to identify differentially expressed lncRNAs (DElncRNAs) and mRNAs (DEmRNAs) that showed differences in expression levels. Next, by literature review of previous studies, we chose two lncRNAs (FENDRR and LINC00092) for additional studies. To validate our findings, a series of tests were performed on a total of 31 tumor tissues and normal paired adjacent tumor tissues. The lncRNA expression levels were assessed in tumor tissues as well as in surrounding normal tumor tissues. RESULTS The data confirmed that just two particular lncRNAs, FENDRR and LINC00092, had considerably decreased expression levels throughout all stages of cancer. In addition, the survival assay was conducted using the GEPIA2 software, revealing that a reduced expression of FENDRR is correlated with a reduced overall survival. Furthermore, our investigation using receiver operating characteristic (ROC) methodology revealed that these two lncRNAs had significant discriminatory ability between colon cancer and normal tissues. To determine the cause of the decrease in the activity of these two long non-coding RNAs (lncRNAs), we used methylation-specific PCR (MSP) to examine the methylation pattern of their promoter regions. Our investigation revealed hypermethylation in the promoter regions of FENDRR and LINC00092 within tumor tissues compared to normal adjacent tumor tissues. CONCLUSION Taken together, our findings revealed the lncRNAs signatures as potential therapeutic targets and molecular diagnostic biomarkers in colon cancer. Furthermore, the evidence provided substantiates the important role of promoter methylation in regulating the expression levels for both of these lncRNAs.

Novel ancestry-specific primary open-angle glaucoma loci and shared biology with vascular mechanisms and cell proliferation. Cell Rep Med 2024; 5:101430.

Abstract
Primary open-angle glaucoma (POAG), a leading cause of irreversible blindness globally, shows disparity in prevalence and manifestations across ancestries. We perform meta-analysis across 15 biobanks (of the Global Biobank Meta-analysis Initiative) (n = 1,487,441: cases = 26,848) and merge with previous multi-ancestry studies, with the combined dataset representing the largest and most diverse POAG study to date (n = 1,478,037: cases = 46,325) and identify 17 novel significant loci, 5 of which were ancestry specific. Gene-enrichment and transcriptome-wide association analyses implicate vascular and cancer genes, a fifth of which are primary ciliary related. We perform an extensive statistical analysis of SIX6 and CDKN2B-AS1 loci in human GTEx data and across large electronic health records showing interaction between SIX6 gene and causal variants in the chr9p21.3 locus, with expression effect on CDKN2A/B. Our results suggest that some POAG risk variants may be ancestry specific, sex specific, or both, and support the contribution of genes involved in programmed cell death in POAG pathogenesis.

Redox Rep 2023; 28:2168626. [PMID: 36719027 PMCID: PMC9891159 DOI: 10.1080/13510002.2023.2168626] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/01/2023] Open
Abstract
Background: Nucleolin is a multifunctional nucleolar protein with RNA-binding properties. Increased nucleolin expression protects cells from H2O2-induced damage, but the mechanism remains unknown. Long noncoding RNAs (lncRNAs) play crucial roles in cardiovascular diseases. However, the biological functions and underlying mechanisms of lncRNAs in myocardial injury remain unclear.Methods: In a nucleolin-overexpressing cardiac cell line, high-throughput technology was used to identify lncRNAs controlled by nucleolin. Cell counting kit-8 assay was used to determine cell viability, lactate dehydrogenase (LDH) assay to detect cell death, caspase activity assay and propidium iodide staining to confirm cell apoptosis, and RNA immunoprecipitation to examine the interaction between Fendrr and nucleolin.Results: We found that Fendrr expression was significantly downregulated in mouse hearts subjected to myocardial ischemia-reperfusion (MI/R) injury. High Fendrr expression abrogated H2O2-mediated injury in cardiomyocytes as evidenced by increased cell viability and decreased cell apoptosis. Conversely, Fendrr knockdown exacerbated the cardiomyocytes injury. Also, nucleolin overexpression inhibits Fendrr downregulation in H2O2-induced cardiomyocyte injury. Fendrr overexpression significantly reversed the role of the suppression of nucleolin expression in H2O2-induced cardiomyocytes.Conclusion: LncRNA Fendrr is involved in the cardioprotective effect of nucleolin against H2O2-induced injury and may be a potential therapeutic target for oxidative stress-induced myocardial injury.

Abstract
Background Long non-coding RNAs (lncRNAs) play an important role in the occurrence of melanoma. However, the specific molecular mechanisms that regulate its biological function are still poorly understood. Therefore, the main purpose of this study is to elucidate the internal mechanism of lncRNA-FENDRR as a biological marker for the occurrence of SKCM and its influence on its proliferation. Results FENDRR is low expressed in skin cutaneous melanoma (SKCM) tissues and appears to be at an even lower level as the tumor progresses. However, the high expression of FENDRR can affect the proliferation of SKCM cell line A375. The results of flow cytometry showed that after overexpression of FENDRR, the cell cycle was arrested in the G1/G0 phase. Bioinformatics analysis and RIP results showed that FENDRR could be combined with YTHDF1. Together, these complexes regulate c-Myc mRNA level and determine cell proliferation. Conclusion We found that overexpression of FENDRR can effectively inhibit SKCM, which provides a new theoretical basis for new therapeutic approaches and targeted RNA drugs.

Abstract
Non-coding DNA accounts for approximately 98.5% of the human genome. Once labeled as "junk DNA", this portion of the genome has undergone a progressive re-evaluation and it is now clear that some of its transcriptional products, belonging to the non-coding RNAs (ncRNAs), are key players in cell regulatory networks. A growing body of evidence demonstrates the crucial impact of regulatory ncRNAs on mammalian gene expression. Here, we focus on the defined relationship between chromatin-interacting RNAs, particularly long non-coding RNA (lncRNA), enhancer RNA (eRNA), non-coding natural antisense transcript (ncNAT), and circular RNA (circRNA) and epigenome, a common ground where both protein and RNA species converge to regulate cellular functions. Through several examples, this review provides an overview of the variety of targets, interactors, and mechanisms involved in the RNA-mediated modulation of loci-specific epigenetic states, a fundamental evolutive strategy to orchestrate mammalian gene expression in a timely and reversible manner. We will discuss how RNA-mediated epigenetic regulation impacts development and tissue homeostasis and how its alteration contributes to the onset and progression of many different human diseases, particularly cancer.

Abstract
Esophageal cancer (ESCA) is a malignant tumor of the upper gastrointestinal tract, with a high mortality rate and poor prognosis. Long noncoding RNAs (lncRNAs) play a role in the malignant progression of tumors by regulating autophagy. This study is aimed at establishing a prognostic model of autophagy-related lncRNAs in ESCA and provide a theoretical basis to determine potential therapeutic targets for ESCA. The transcriptome expression profiles were downloaded from The Cancer Genome Atlas (TCGA). We identified autophagy-related mRNAs and lncRNAs in ESCA using differential expression analysis and the Human Autophagy Database (HADb). Four differentially expressed autophagy-related lncRNAs with a prognostic value were identified using Cox regression and survival analyses. Furthermore, the combination of the selected lncRNAs was able to predict the prognosis of patients with ESCA more accurately than any of the four lncRNAs individually. Finally, we constructed a coexpression network of autophagy-related mRNAs and lncRNAs. This study showed that autophagy-related lncRNAs play an important role in the occurrence and development of ESCA and could become a new target for the diagnosis and treatment of this disease.

Abstract
The prognosis of the most common histological subtype of lung cancer, lung adenocarcinoma (LUAD), is relatively poor. Mitochondrial homeostasis depends to a great extent on the coordination between mitophagy and mitochondrial biogenesis, the deregulation of which causes various human diseases, including cancer. There is accumulating evidence that long noncoding RNAs (lncRNAs) are critical in predicting the prognosis and immune response in carcinoma. Therefore, it is critical to discern lncRNAs related to mitochondrial homeostasis in LUAD patients. In this study, we identified mitochondrial homeostasis–related lncRNAs (MHRlncRNAs) by coexpression analysis. In order to construct a prognostic signature composed of three MHRlncRNAs, univariate and multivariate Cox regression analyses were performed. Kaplan–Meier analysis, stratification analysis, principal component analysis (PCA), receiver operating characteristic (ROC) curve, gene set enrichment analysis (GSEA), and nomogram were applied to evaluate and optimize the risk model. Subsequently, we identified the mitochondrial homeostasis–related lncRNA signature (MHLncSig) as an independent predictive factor of prognosis. Based on the LUAD subtypes regrouped by this risk model, we further investigated the underlying tumor microenvironment, tumor mutation burden, and immune landscape behind different risk groups. Likewise, individualized immunotherapeutic strategies and candidate compounds were screened to aim at different risk subtypes of LUAD patients. Finally, we validated the expression trends of lncRNAs included in the risk model using quantitative real-time polymerase chain reaction (qRT-PCR) assays. The established MHLncSig may be a promising tool for predicting the prognosis and guiding individualized treatment in LUAD.

Abstract
Abstract
Background
Accumulating evidence indicates that long non-coding RNAs (lncRNAs) are involving in the tumorigenesis and metastasis of lung cancer. The aim of the study is to systematically characterize the lncRNA-associated competing endogenous RNA (ceRNA) network and identify key lncRNAs in the development of stage I lung adenocarcinoma (LUAD).
Methods
Totally, 1,955 DEmRNAs, 165 DEmiRNAs and 1,107 DElncRNAs were obtained in 10 paired normal and LUAD tissues. And a total of 8,912 paired lncRNA-miRNA-mRNA network was constructed. Using the Cancer Genome Atlas (TCGA) dataset, the module of ME turquoise was revealed to be most relevant to the progression of LUAD though Weighted Gene Co-expression Network Analysis (WGCNA).
Results
Of the lncRNAs identified, LINC00639, RP4-676L2.1 and FENDRR were in ceRNA network established by our RNA-sequencing dataset. Using univariate Cox regression analysis, FENDRR was a risk factor of progression free survival (PFS) of stage I LUAD patients (HRs = 1.69, 95%CI 1.07–2.68, P < .050). Subsequently, diffe rential expression of FENDRR in paired normal and LUAD tissues was detected significant by real-time quantitative (qRT-PCR) (P < 0.001).
Conclusions
This study, for the first time, deciphered the regulatory role of FENDRR/miR-6815-5p axis in the progression of early-stage LUAD, which is needed to be established in vitro and in vivo.

Online bioinformatics database predicted and screened miR-421 as a potential target of FENDRR, and SIRT3 was predicted as a target gene of miR-421. The pcDNA-SIRT3 or si-SIRT3 was transfected into AGS cells, and cell proliferation, invasion, apoptosis and Notch-1 protein expression were determined. Ad-FENDRR was transfected into AGS and SGC-7901 cells alone or together with miR-421 mimic to explore the effect of miR-421 on cells. The AGS cells transfected with Ad-FENDRR were injected into the armpits of nude mice to establish subcutaneous xenograft tumor model, and tumor growth was observed. Results FENDRR expression was downregulated in GC tissues and cell lines. Overexpression of FENDRR or SIRT3 inhibited tumor proliferation and invasion, and promoted apoptosis. The overexpression of Notch-1 reversed the inhibitory effect of SIRT3 on AGS cell. MiR-421 mimic reversed the inhibitory effect of FENDRR on the growth of AGS and SGC-7901 cells. Nude mice injected with FENDRR overexpressing AGS cells had smaller tumor volume and weight and weaker tumor cell proliferation ability. Conclusion FENDRR inhibits Notch-1 pathway to inhibit GC cell proliferation and invasion by upregulating SIRT3 expression via targeting miR-421.

Yang F, Sun S, Yang F. Prognostic and Predicted Significance of FENDRR in Colon and Rectum Adenocarcinoma. Front Oncol 2021; 11:668595. [PMID: 34621665 PMCID: PMC8490734 DOI: 10.3389/fonc.2021.668595] [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: 02/16/2021] [Accepted: 09/06/2021] [Indexed: 12/19/2022] Open
Abstract
Background The role of fetal-lethal non-coding developmental regulatory RNA (FENDRR) has been explored in various cancers; however, its relationship with colon adenocarcinoma/rectum adenocarcinoma (COAD/READ) remains unclear. The objectives of this study were to identify and assess any associations between FENDRR and COAD/READ using The Cancer Genome Atlas (TCGA) database and the Genetic Data Commons (GDC) Data Portal. Methods The records of patients with COAD/READ were collected from the GDC Data Portal. After comparing the expression level of FENDRR in COAD/READ and healthy tissues, we evaluated the association of FENDRR with clinicopathological characters and the survival rate, the impact of FENDRR on prognosis, the biological function of FENDRR, and the relative abundance of tumor-infiltrating immune cells in patients with COAD/READ. Moreover, we aimed to construct a protein-protein interaction (PPI) network for selecting genes and a ceRNA network for presenting mRNA-miRNA-lncRNA interactions. Results In patients with COAD/READ, FENDRR expression could differentiate tumor tissues from the adjacent healthy tissues since it was significantly lower in the former than in the latter. High FENDRR expression was correlated with poorer survival and higher tumor stage, current tumor stage, and metastasis stage, and also exhibited high scores for apoptosis, autophagy, and senescence. Immune cell infiltration analysis showed that the high expression group had significantly lower immune and stromal scores. Low FENDRR expression was correlated with poor overall survival (OS), and thus, it could serve as an independent risk factor. The prognostic models constructed in the study performed well for the prediction of OS and disease-specific survival (DFS) using FENDRR expression. Gene set enrichment analysis revealed that vascular smooth muscle contraction, melanogenesis, basal cell carcinoma, and Hedgehog signaling pathways were significantly enriched in patients with high FENDRR expression. Eight hub genes, namely, PKM, ALDOA, PFKP, ALDOC, PYGL, CTNNB1, PSMA5, and WNT5A, were selected from the PPI network, and a ceRNA network was constructed based on the differentially expressed mRNAs, miRNAs, and lncRNAs to illustrate their regulatory relationships. Conclusion FENDRR may serve as a potential biomarker for the diagnosis and prognosis of COAD/READ.

Abstract
Background The competitive endogenous RNA (ceRNA) mechanism has been discovered recently and regulating cancer-related gene expressions. The ceRNA network participates in multiple processes, such as cell proliferation and metastasis, and potentially drives the progression of cancer. In this study, we focus on the ceRNA networks of esophageal squamous cell carcinoma and discovered a novel biomarker panel for cancer prognosis. Methods RNA expression data of esophageal carcinoma from the TCGA database were achieved and constructed ceRNA network in esophageal carcinoma using R packages. Results Four miRNAs were discovered as the core of the ceRNA model, including miR-93, miR-191, miR-99b, and miR-3615. Moreover, we constructed a ceRNA network in esophageal carcinoma, which included 4 miRNAs and 6 lncRNAs. After ceRNA network modeling, we investigated six lncRNAs which could be taken together as a panel for prognosis prediction of esophageal cancer, including LINC02575, LINC01087, LINC01816, AL136162.1, AC012073.1, and AC117402.1. Finally, we tested the predictive power of the panel in all TCGA samples. Conclusions Our study discovered a new biomarker panel which may have potential values in the prediction of prognosis of esophageal carcinoma.

Abstract
Colorectal cancer (CRC) has the characteristics of high morbidity and mortality. LncRNA not only participates in the progression of CRC through genes and transcription levels, but also regulates the tumor microenvironment and leads to the malignant phenotype of tumors. Therefore, we identified immune-related LncRNAs for the construction of clinical prognostic model. We searched The Cancer Genome Atlas (TCGA) database for original data. Then we identified differentially expressed irlncRNA (DEirlncRNA), which was paired and verified subsequently. Next, univariate analysis, Lasso and Cox regression analysis were performed on the DEirlncRNA pair. The ROC curve of the signature was drawn, and the optimal cut-off value was found. Then the cohort was divided into a high-risk and a low-risk group. Finally, we re-evaluated the signature from different perspectives. A total of 16 pairs of DEirlncRNA were included in the construction of the model. After regrouping according to the cut-off value of 1.275, the high-risk group showed adverse survival outcomes, progressive clinicopathological features, specific immune cell infiltration status, and high sensitivity to some chemotherapy drugs. In conclusion, we constructed a signature composed of immune-related LncRNA pair with no requirement of the specific expression level of genes, which shows promising clinical predictive value in CRC patients.

Abstract
BACKGROUND Long noncoding RNA (lncRNA) fetal-lethal non-coding developmental regulatory RNA (FENDRR), a newly known lncRNA, has been reported to be abnormally expressed in diverse tumors. This review is focused on clarifying the mechanism of FENDRR to regulate the biological process of tumors, affirming its value as a target for tumor therapy. METHODS The pathophysiological mechanism of FENDRR acting on tumors has been analyzed and summarized by reviewing PubMed. RESULTS The expression of lncRNA FENDRR is abnormally altered in clinical cancers, promoting the malignant transformation of a variety of tumors, including colon cancer, cervical cancer, hepatocellular carcinoma, prostate cancer, Malignant melanoma, lung cancer, osteosarcoma, breast cancer, etc. Cellular processions, including proliferation, invasion, apoptosis and migration affected by FENDRR, have been revealed. CONCLUSION Specific evidences for the involvement of LncRNA FENDRR in cancer regulatory processes suggest that FENDRR has the potential to be a biomarker or clinical therapeutic target for malignant tumors.

Abstract
Lung adenocarcinoma (LUAD) is the most common subtype of lung cancer, but the prognosis of LUAD patients remains unsatisfactory. Here, we retrieved the RNA-seq data of LUAD cohort from The Cancer Genome Atlas (TCGA) database and then identified differentially expressed immune-related lncRNAs (DEirlncRNAs) between LUAD and normal controls. Based on a new method of cyclically single pairing along with a 0-or-1 matrix, we constructed a novel prognostic signature of 8 DEirlncRNA pairs in LUAD with no dependence upon specific expression levels of lncRNAs. This prognostic model exhibited significant power in distinguishing good or poor prognosis of LUAD patients and the values of the area under the curve (AUC) were all over 0.70 in 1, 3, 5 years receiver operating characteristic (ROC) curves. Moreover, the risk score of the model could serve as an independent prognostic factor for patients with LUAD. In addition, the risk model was significantly associated with clinicopathological characteristics, tumor-infiltrating immune cells, immune-related molecules and sensitivity of anti-tumor drugs. This novel signature of DEirlncRNA pairs in LUAD, which did not require specific expression levels of lncRNAs, might be used to guide the administration of patients with LUAD in clinical practice.

Abstract
The multifunctional protein, splicing factor, proline- and glutamine-rich (SFPQ) has been implicated in numerous cancers often due to interaction with coding and non-coding RNAs, however, its role in melanoma remains unclear. We report that knockdown of SFPQ expression in melanoma cells decelerates several cancer-associated cell phenotypes, including cell growth, migration, epithelial to mesenchymal transition, apoptosis, and glycolysis. RIP-seq analysis revealed that the SFPQ-RNA interactome is reprogrammed in melanoma cells and specifically enriched with key melanoma-associated coding and long non-coding transcripts, including SOX10, AMIGO2 and LINC00511 and in most cases SFPQ is required for the efficient expression of these genes. Functional analysis of two SFPQ-enriched lncRNA, LINC00511 and LINC01234, demonstrated that these genes independently contribute to the melanoma phenotype and a more detailed analysis of LINC00511 indicated that this occurs in part via modulation of the miR-625-5p/PKM2 axis. Importantly, analysis of a large clinical cohort revealed that elevated expression of SFPQ in primary melanoma tumours may have utility as a prognostic biomarker. Together, these data suggest that SFPQ is an important driver of melanoma, likely due to SFPQ-RNA interactions promoting the expression of numerous oncogenic transcripts.

Abstract
This study aimed to investigate the role of lncRNA FENDRR in apoptosis of Leydig cells and the further mechanism. The apoptosis of Leydig cells (TM3 cell line) was induced by H2O2-treatment and detected by flow cytometry. The function of FENDRR was determined by in vitro and in vivo silencing experiments. The mechanism of FENDRR in regulating the expression of nuclear factor erythroid 2-related factor 2 (Nrf2) was assessed by RNA immunoprecipitation, RNA pull-down, and ubiquitination assays. FENDRR expression was up-regulated in H2O2-treated TM3 cells. Knockdown of FENDRR augmented Nrf2 and HO-1 protein levels and testosterone production in H2O2-treated TM3 cells, whereas the apoptosis rate and caspase 3 activity were decreased. Mechanically, FENDRR bound to Nrf2 and promoted its ubiquitination and degradation. Nrf2 overexpression reversed the effects FENDRR overexpression on apoptosis, caspase 3 activity, and testosterone concentration in H2O2-treated TM3 cells. The in vivo experiments showed that FENDRR silence increased serum testosterone level and improved testosterone-related anti-depression behaviors of late-onset hypogonadism (LOH) mice. Our findings suggested that FENDRR could promote apoptosis of Leydig cells in LOH partly through facilitating Nrf2 degradation.

Abstract
FENDRR (Fetal-lethal non-coding developmental regulatory RNA, LncRNA FOXF1-AS1) is a recently identified tumor suppressor long non-coding (LncRNA) RNA, and its expression has been linked with epigenetic modulation of the target genes involved in tumor immunity. In this study, we aimed to understand the role of FENDRR in predicting immune-responsiveness and the inflammatory tumor environment. Briefly, FENDRR expression and its relationship to immune activation signals were assessed in murine cell lines. Data suggested that tumor cells (e.g., C26 colon, 4T1 breast) that typically upregulate immune activation genes and the MHC class I molecule exhibited high FENDRR expression levels. Conversely, tumor cells with a generalized downregulation of immune-related gene expression (e.g., B16F10 melanoma) demonstrated low to undetectable FENDRR levels. Mechanistically, the modulation of FENDRR expression enhanced the inflammatory and WNT signaling pathways in tumors. Our early data suggest that FENDRR can play an important role in the development of immune-relevant phenotypes in tumors, and thereby improve cancer immunotherapy.

Abstract
Dysregulation of long noncoding RNA (LncRNA) FENDDR has been shown to be closely related to the progression of several cancers. However, its role and upstream regulatory mechanism in endometrioid endometrial carcinoma (EEC) remains unclear. This study was conducted using the cancerous tissues of EEC patients (n = 60), EEC cell lines, and a xenograft mouse model. The expression level of LncRNA FENDRR was decreased and the N-methyladenosine (m6A) methylation levels of LncRNA FENDRR was elevated in cancerous tissues of EEC patients. In vitro experiments demonstrated that YTH domain-containing 2 (YTHDF2), an m6A reader, recognized the abundance of m6A-modified LncRNA FENDRR in EEC cells and promoted its degradation. LncRNA FENDRR overexpression suppressed cell proliferation and facilitated cell apoptosis in the EEC cell line HEC-1B by reducing the protein level of SRY-related HMG box transcription factor 4 (SOX4). Interference of LncRNA FENDRR reversed the inhibitory effect of sh-YTHDF2 on cell proliferation and the promoting effect of sh-YTHDF2 on cell apoptosis in HEC-1B cells by silencing FENDRR. Finally, in vivo experiments confirmed that overexpression of LncRNA FENDRR retarded the growth of EEC cells. In conclusion, YTHDF2-mediated LncRNA FENDRR degradation promotes cell proliferation by elevating SOX4 expression in EEC.

Abstract
The dysregulation of long non-coding RNAs (lncRNAs) and transcription factors (TFs) is closely related to the development and progression of drug resistance in cancer chemotherapy. However, their regulatory interactions in the multidrug resistance (MDR) of gastric cancer (GC) has largely remained unknown. In this study, we report a novel oncogenic role of lncRNA FENDRR in conferring MDR in GC by coordinated regulation of FOXC2 expression at the transcriptional and posttranscriptional levels. In vitro and in vivo experiments demonstrated that downregulation of FENDRR expression remarkably decreased drug resistant ability of GC MDR cells while upregulation of FENDRR expression produced the opposite effect. FENDRR overexpression was observed in MDR GC cell lines, patient-derived xenografts, and clinical samples. And the high levels of FENDRR expression were correlated with poor prognosis in GC patients. Regarding the mechanism, FENDRR was revealed to increase proto-oncogene FOXC2 transcription by performing an enhancer-like role in the nucleus and by sponging miR-4700-3p in the cytoplasm. Both FOXC2 and miR-4700-3p were shown to be functionally involved in the FENDRR-induced chemoresistance. In addition, there is a positive correlation between FENDRR and FOXC2 expression in clinic and the overexpressed FOXC2 indicated a poor prognosis in GC patients. Collectively, our findings provide a new perspective for the lncRNA-TF regulatory interaction involved in MDR, suggesting that targeting the FENDRR/FOXC2 axis may be an effective approach to circumvent GC chemoresistance.

Abstract
Long non-coding RNAs (lncRNAs) have more than 200 nucleotides and do not encode proteins. Based on numerous studies, lncRNAs have emerged as new and crucial regulators of biological function and have been implicated in the pathogenesis of a variety of diseases, especially cancers. Specific lncRNAs have been identified as novel molecular biomarkers for cancer diagnosis, prognosis, and treatment efficacy. Fetal-lethal non-coding developmental regulatory RNA (FENDRR, also known as FOXF1-AS1) is a novel lncRNA that is located at chr3q13.31 and has four exons and 3099 nucleotides, and its genomic site is located at chr3q13.31. FENDRR is abnormally expressed in a variety of cancers and is significantly associated with different clinical characteristics. In addition, FENDRR has shown potential as a biomarker for cancer diagnosis, prognosis, and treatment. In this review, we summarize the current understanding of FENDRR and its mechanistic role in cancer progression. We also discuss recent insights into the clinical significance of FENDRR for cancer diagnosis, prognosis, and treatment.

Abstract
Objective: LncRNAs are non-coding RNAs exerting vital roles in the occurrence and
development of various cancer types. This study tended to describe the
expression pattern of FENDRR in colorectal cancer (CRC), and further
investigate the role of FENDRR in CRC cell biological behaviors. Methods: Gene expression profile of colon cancer was accessed from the TCGA database,
and then processed for differential analysis for identification of
differentially expressed lncRNAs and miRNAs. Some in vitro
experiments like qRT-PCR, MTT, colony formation assay, wound healing assay
and Transwell assay were performed to assess the effect of FENDRR on cell
biological behaviors. Dual-luciferase reporter assay was conducted to
further validate the targeting relationship between FENDRR and miR-424-5p,
and rescue experiments were carried out for determining the mechanism of
FENDRR/miR-424-5p underlying the proliferation, migration and invasion of
CRC cells. Results: Bioinformatics analysis suggested that FENDRR was significantly
down-regulated in CRC tissue, and low FENDRR was intimately correlated to
poor prognosis. FENDRR overexpression could greatly inhibit cell
proliferation, migration and invasion. Besides, there was a negative
correlation between FENDRR and miR-424-5p. Dual-luciferase reporter assay
indicated that miR-424-5p was a direct target of FENDRR. Rescue experiments
discovered that FENDRR exerted its role in cell proliferation, migration and
invasion in CRC via targeting miR-424-5p. Conclusion: FENDRR is poorly expressed in CRC tissue and cells, and low FENDRR is
responsible for the inhibition of cell proliferation, migration and invasion
of CRC by means of targeting miR-424-5p.

Abstract
Breast cancer is the leading cause of cancer-related death among women. Recurrence of primary tumor and metastasis to distant body parts are major causes of breast cancer-associated mortality. The 5-year survival rate for women with metastatic breast cancer is only 25-30%. Breast cancer metastasis is a series of processes involved with EMT, invasion, loss of cell to cell adhesion, alteration in cell phenotype, extravasation, microenvironment of the tumor, and colonization to the secondary sites. Epigenetic modification is involved in the transformation of the distant stromal cell into a secondary tumor. LncRNAs, are one the key epigenetic modifiers, are the largest endogenous non-coding RNAs with approximate base-pair lengths from 200 nt to 100 kb. LncRNA plays a crucial role in breast cancer metastasis by sponging miRNA, by degrading or silencing specific mRNA, or else by targeting the enzymes and microprocessor subunits involved in the biogenesis of miRNA. LncRNA also alters the expression of several genes involved in breast cancer metastasis and modulating different cell signaling pathways. The goal of this review is to provide a better understanding of the role of lncRNA in the regulation of breast cancer metastasis. We also summarized some of the key lncRNAs that regulate the genes and signaling pathways involved in breast cancer invasion and metastasis.

Carbohydrate Sulfotransferase 4 Inhibits the Progression of Hepatitis B Virus-Related Hepatocellular Carcinoma and Is a Potential Prognostic Marker in Several Tumors. Front Oncol 2020; 10:554331.

Abstract
Carbohydrate sulfotransferase 4 (CHST4) plays an important role in lymphocyte homing and is abnormally expressed in several cancer types; however, its precise function in tumor development and progression is unknown. Here we confirm that CHST4 is aberrantly expressed in various tumor subtypes. In particular, we found that CHST4 expression was downregulated in hepatitis B virus-related hepatocellular carcinoma (HBV-HCC) tumors compared to paired normal tissue. We also showed that CHST4 overexpression inhibited the proliferation and metastasis of HCC cells in vitro. Clinically, CHST4 was identified as an independent prognostic factor for HBV-HCC patients. We further illuminated the anti-tumor role and mechanism of CHST4 in HBV-HCC by constructing a FENDRR–miR-10b-5p–CHST4 competing endogenous RNA network. We found that downregulation of CHST4 expression may promote HBV expression and regulate ribonucleoprotein complex biogenesis to promote malignant behaviors in HBV-HCC. CHST4 may also recruit CD4+ T cells, macrophages, dendritic cells, and neutrophils into the tumor microenvironment to inhibit the progression of HBV-HCC. Overall, our findings suggest that CHST4 acts as a tumor suppressor in HCC-HBV and represents a potential diagnostic and therapeutic target.

Abstract
Alkylglycerone phosphate synthase (AGPS) is a key enzyme for ether ester synthesis and acts as an oncogene in malignant tumors. The present study aimed to investigate the effect of AGPS silencing on the expression levels of long non-coding RNAs (lncRNAs) and the co-expression with mRNAs in glioma U251 cells using microarray analysis. Furthermore, the underlying biological functions of crucial lncRNAs identified were investigated. It was discovered that in vitro U251 cell proliferation was suppressed following the genetic silencing of AGPS. Differentially expressed lncRNAs and mRNAs in U251 cells were sequenced following AGPS silencing. The results from the Gene Ontology analysis identified that the co-expressed mRNAs were mainly involved in biological processes, such as 'cellular response to hypoxia', 'extracellular matrix organization' and 'PERK-mediated unfolded protein response'. In addition, Kyoto Encyclopedia of Genes and Genomes signaling pathway enrichment analysis revealed that the co-expressed mRNAs were the most enriched in the 'AGE/RAGE signaling pathway in diabetic conditions'. Additionally, the PI3K/Akt and epidermal growth factor receptor signaling pathways serve important roles in tumor processes, for example carcinogenesis and angiogenesis. Furthermore, it was identified that the lncRNA AK093732 served a vital role in the regulatory network and the core pathway in this network regulated by this lncRNA was discovered to be the 'Cytokine-cytokine receptor interaction'. In conclusion, the findings of the present study suggested that AGPS may affect cell proliferation and the degree of malignancy. In addition, the identified lncRNAs and their co-expressed mRNAs screened using microarrays may have significant biological effects in the occurrence, development and metastasis of glioma, and thus may be novel markers of glioma.

Abstract
There is increasing evidence has indicated that long non-coding RNAs (lncRNAs) are implicated in the tumorigenesis and development of colorectal cancer (CRC). Nevertheless, the clinical significances and functions of FENDRR in CRC remain unknown. In this study, we reveal that lncRNA FENDRR is downregulated in CRC and negatively correlated with advanced stage and poor clinical outcomes of patient with CRC. Overexpression of FENDRR represses the proliferation, migrate and invasive capacities of CRC cell in vitro, and upregulation of FENDRR inhibits the growth and distant metastatic capacity of CRC cell in vivo. Mechanistically, FENDRR interacts with miRNA-18a-5p (miR-18a-5p) and subsequently regulates the expression of inhibitor of growth 4 (ING4) in CRC cell. Interestingly, ING4 repression or miR-18a-5p rescues FENDRR induced proliferation and aggressive phenotypes inhibition of CRC cell. Altogether, our findings suggest that FENDRR exerts an inhibitory role in CRC by interacting with miR-18a-5p and future increases ING4 expression.

Abstract
Background Previous literature has revealed long non-coding RNAs (lncRNAs) are crucial regulators for cell functions and gene expression. LncRNA fetal-lethal non-coding developmental regulatory RNA (FENDRR) was reported as a biological suppressor in several types of human cancers, yet relevant mechanisms and biological effects of FENDRR with regards to cervical cancer (CC) are not explored until now. Methods In this study, quantitative real-time polymerase chain reaction (qRT-PCR) analysis detected gene expression in tissues and cells. Gain- or loss-of-function experiments revealed the biological effects of FENDRR and miR-15a/b-5p on CC cell functions. Bioinformatics tools were used to predict the relevant genes. Mechanism experiments including RNA immunoprecipitation (RIP) assay, pull down assay and luciferase reporter assay depicted the binding situation and coexistence of indicated genes. Results FENDRR was downregulated in CC tissues and cells, which suppressed CC progression. MiR-15a-5p and miR-15b-5p shared binding sites with FENDRR and had interaction with FENDRR. Tubulin alpha1A (TUBA1A) was downregulated in CC tissues and positively modulated by FENDRR. TUBA1A was the target of miR-15a/b-5p. TUBA1A silencing rescued the effect of FENDRR overexpression on CC cell growth and migration. Conclusion FENDRR inhibits CC progression through upregulating TUBA1A in a miR-15a/b-5p-dependent manner.

Abstract
Long non-coding RNAs (lncRNAs) are RNAs with lengths exceeding 200 nucleotides that are not translated into proteins. It is well-known that small non-coding RNAs, such as microRNAs (miRNAs), regulate gene expression and play an important role in cholangiopathies. Recent studies have demonstrated that lncRNAs may also play a key role in the pathophysiology of cholangiopathies. Patients with cholangiopathies often develop cholangiocarcinoma (CCA), which is cholangiocyte-derived cancer, in the later stage. Cholangiocytes are a primary target of therapies for cholangiopathies and CCA development. Previous studies have demonstrated that expression levels of lncRNAs are altered in the liver of cholangiopathies or CCA tissues. Some lncRNAs regulate gene expression by inhibiting functions of miRNAs leading to diseased liver conditions or CCA progression, suggesting that lncRNAs could be a novel therapeutic target for those disorders. This review summarizes current understandings of functional roles of lncRNAs in cholangiopathies and seek their potentials for novel therapies.

Abstract
Purpose Long intergenic noncoding RNA 01121 (LINC01121) has been reported to be aberrantly expressed and acts as an oncogene in pancreatic cancer. However, the detailed molecular mechanism of LINC01121 in breast cancer remains largely unclear. In this study, we aimed to investigate the expression and biological function of LINC01121 in breast cancer. Methods LINC01121 and miR-150-5p expression were measured in breast cancer cell lines using quantitative reverse transcription PCR. MTS and flow cytometry assays were performed to determine cell proliferation, the cell cycle, and apoptosis. Cell migration and invasion were assessed by transwell assay. The protein expression of HMGA2 in breast cancer cell lines was measured by Western blotting. A luciferase reporter assay was used to assess the binding of LINC01121 and miR-150-5p. Results We found that LINC01121 was markedly up-regulated in breast cancer cell lines compared with normal breast epithelial cells. LINC01121 down-regulation markedly suppressed cell proliferation, cell cycle progression, migration, and invasion and promoted apoptosis in breast cancer cells. Further investigation showed that LINC01121 could serve as a molecular sponge for miR-150-5p and indirectly modulate the expression of its target, HMGA2. Moreover, miR-150-5p knockdown rescued the effects of LINC01121 down-regulation on HMGA2 protein expression, cell proliferation, cell cycle progression, apoptosis, migration, and invasion in breast cancer cells. Conclusion Knockdown LINC01121 inhibited breast cancer cell proliferation, migration, and invasion via the miR-150-5p/HMGA2 axis.

Abstract
Long noncoding RNAs have an essential role in the tumorigenesis of breast cancer (BC). Nonetheless, the consequences of long intergenic noncoding RNA 00641 (LINC00641) in BC remain unidentified. This study shows that LINC00641 expression level was decreased in BC tissues. LINC00641 expression level was negatively related to tumor size, lymph-node metastasis, as well as clinical stage. LINC00641 overexpression inhibited cell proliferation, migration, and invasion but stimulated apoptosis in BC cells. LINC00641 overexpression also remarkably reduced BC growth and metastasis in vivo. LINC00641 acts as a competitive endogenous RNA to sponge miR-194-5p. miR-194-5p level was higher in BC tissues and cells compared with normal-adjacent tissues and normal breast epithelial cell. miR-194-5p expression was negatively correlated with LINC00641 expression in BC tissues. miR-194-5p overexpression reversed the effects of LINC00641 on cell proliferation, cycle, apoptosis, migration, as well as invasion. In conclusion, LINC00641 inhibits BC cell proliferation, migration, as well as invasion by sponging miR-194-5p.

Abstract
To explore the roles of long noncoding RNA (lncRNA) FOXF1 Adjacent Non-Coding Developmental Regulatory RNA (FENDRR) in human non-small cell lung cancer (NSCLC). The levels of FENDRR in NSCLC cells and tissues were analyzed using qRT-PCR assay. The growth and colony formation abilities of NSCLC cell were analyzed by the MTT and colony formation tests. The mobility and invasiveness of NSCLC cell were analyzed using the wound closure and Transwell invasion assay. The impact of FENDRR on the tumor growth of NSCLC cells in vivo was detected using xenograft model. Bioinformatics analysis and luciferase reporter gene bioassay were selected to identify the bindings sites between miR-761 and FENDRR. Additional, the results of Transwell invasion and colony formation experiments indicated that FENDRR inhibited the aggressiveness of NSCLC depend on miR-761. Tissue inhibitor of metalloproteinase 2 (TIMP2) was identified as the downstream target of miR-761 and its level was positively regulated by FENDRR. Cotransfection assays using A549 and H1975 cells future implied that downexpression of TIMP2 rescued the aggressiveness phenotypes of NSCLC cell inhibited by FENDRR. Altogether, we demonstrated that lncRNA FENDRR suppressed the progression of NSCLC via binding to miR-761 and regulating TIMP2 expression.

FEBS Lett 2019; 593:1993-2007.

Abstract
Chemotherapy is a major anticancer therapeutic modality, however, multidrug resistance (MDR) is frequently observed and hinders treatment efficacy. Here, we investigated the role and potential mechanism of the long noncoding RNA (lncRNA) FENDRR in adriamycin resistance of chronic myeloid leukaemia (CML) cells. FENDRR overexpression attenuates adriamycin resistance, as shown by increased Rhodamine 123 accumulation, promotion of cell apoptosis in vitro and suppression of tumour growth in vivo. Mechanistically, we identified that FENDRR reduces the interaction of the RNA-binding protein HuR with MDR1 via acting as a sponge, and miR-184 competitively binds to FENDRR with HuR. Thus, the HuR/FENDRR/miR-184 interaction contributes to MDR1 activity. These findings indicate that FENDRR is a potential target for reversing adriamycin resistance.

MOLECULAR THERAPY-NUCLEIC ACIDS 2019; 17:516-529. [PMID: 31351327 PMCID: PMC6661302 DOI: 10.1016/j.omtn.2019.05.027] [Citation(s) in RCA: 90] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/22/2019] [Revised: 05/30/2019] [Accepted: 05/31/2019] [Indexed: 12/15/2022]
Abstract
Long non-coding RNAs (lncRNAs) have been known to partake in the development and the immune escape of hepatocellular carcinoma (HCC). The initial microarray analysis of GSE115018 expression profile revealed differentially expressed lncRNA fetal-lethal non-coding developmental regulatory RNA (FENDRR) in HCC. Therefore, this study’s main purpose was to explore the mechanism of tumor suppressor lncRNA FENDRR in regulating the immune escape of HCC cells. Notably, it was further validated through this study that lncRNA FENDRR competitively bound to microRNA-423-5p (miR-423-5p), and miR-423-5p specifically targeted growth arrest and DNA-damage-inducible beta protein (GADD45B). The effects that lncRNA FENDRR and miR-423-5p have on the cell proliferation and apoptosis, the immune capacity of regulatory T cells (Tregs), and the tumorigenicity of HCC cells were examined through overexpressing or the knocking down of lncRNA FENDRR and miR-423-5p both in vitro and in vivo. Subsequently, lncRNA FENDRR and GADD45B were revealed to have poor expressions in HCC. Meanwhile, miR-423-5p was highly expressed in HCC. Importantly, overexpressed lncRNA FENDRR and downregulated miR-423-5p diminished cell proliferation and tumorigenicity, and promoted apoptosis in HCC cells, thus regulating the immune escape of HCC mediated by Tregs. Taken conjointly, lncRNA FENDRR inhibited the Treg-mediated immune escape of HCC cells by upregulating GADD45B by sponging miR-423-5p.

Abstract
Background and purpose: Homo sapiens FOXF1 adjacent noncoding developmental regulatory RNA (FENDRR) is a novel long noncoding RNA (lncRNA) exerting important effects on transcriptional and post-transcriptional regulation. The purpose of this study was to investigate the potential role of FENDRR in colon cancer. Methods: Multiple cellular and molecular biology experiments were performed in the present study, such as CCK-8, Western blot, immunohistochemistry, confocal immunofluorescent and animal studies. Results: We determined that attenuation of FENDRR was a frequent event in colon cancer tissues and colon cancer cell lines, in contrast to their normal counterparts. Low levels of FENDRR were associated with the clinical stages and poor prognosis. Moreover, ectopic expression of FENDRR repressed colon cancer cell viability, invasion and epithelial-mesenchymal transition. Furthermore, through a series of in vitro and in vivo assays, we reported the discovery of FENDRR modulating the expression of SOX4 protein, and hence in the progression of colon cancer. Conclusion: Based on these data, we demonstrated that FENDRR may function as a tumor-suppressor gene by repressing SOX4 and as a potential therapeutic target for colon cancer.

Abstract
Endometrial cancer (EC) is a common malignant tumor of the female reproductive system in the world. For most of the treated patients, although the survival rate is improved, most patients still have a poor prognosis. The pathogenesis of EC has always been a strong scientific focus, but there is no clear conclusion. Therefore, in view of modularization, this study is to conduct an in-depth analysis on the effects of estrogen receptor alpha (ERα) regarding EC. The purpose is to identify the molecular course of EC. We obtained 10 co-expression modules, in which ANO2, EMP3, and other genes are significantly differentially expressed in patients with EC. Additionally, there are active regulatory effects in dysfunction modules, thus genes such as ANO2 and EMP3 would be identified as key genes, which are associated with the development of EC. Enrichment results showed that the module genes were significantly involved in RNA splicing, covalent chromatin modification, histone modification, and organelle fission, and other biological processes, as well as significantly regulated mitogen-activated protein kinases (MAPK) signaling pathway, Endocytosis, Rap1 signaling pathway, and viral carcinogenesis, and other signaling pathways. Finally, we identified noncoding RNA pivot including FENDRR, miR-520c-3p. Besides, transcription factors pivot including NFKB1, E2F1, and RELA which significantly regulate dysfunction module genes. Overall, our work deciphered a co-expression network involving differential gene regulation in ERα-associated EC. It helps reveal the core modules and potential regulatory factors of the diseases and enhances our understanding of the pathogenesis. More importantly, we revealed that ERα activates the MAPK signaling pathway to promote the development of EC. It helps to provide a new reference for later research.

Abstract
ABSTRACT
The study aimed to investigate the role of lncRNA FENDRR in proliferation and angiogenesis of human retinal endothelial cells (HRECs). HRECs were cultured in high-glucose medium to mimic diabetic retinopathy (DR) model. We overexpressed or knocked down FENDRR in HRECs to evaluate the effect of FENDRR expression on cell proliferation, migration, and capillary morphogenesis of HRECs under either normal glucose or high glucose condition. Results showed that VEGF and FENDRR expression were increased in blood from DR patients compared with the control subjects. Furthermore, high glucose treatment upregulated expression of VEGF and FENDRR secreted from HRECs, in a dose- and time-dependent manner. Importantly, FENDRR overexpression significantly promoted the high-glucose-induced proliferation, migration, capillary morphogenesis, and VEGF expression in HRECs. In contrast, FENDRR knockdown exerted the opposite effects. In conclusion, lncRNA FENDRR promotes the high-glucose-induced proliferation and angiogenesis of HRECs and may serve as a potential target for anti-angiogenic therapy for DR.

Abstract
BACKGROUND Annexin A2 (ANXA2) plays a crucial role in acute pancreatitis (AP). However, its potential mechanism remains unclear. METHODS In the present study, we used caerulein-treated AR42J rat pancreatic acinar cells as cell model of AP to investigate the potential functions of ANXA2 and its predicted long noncoding RNA (lncRNA) FOXF1 adjacent noncoding developmental regulatory RNA (lncRNA Fendrr). Cell apoptosis was evaluated by flow cytometry using annexinV-fluorescein isothiocyanate/propidium iodide staining. The expressions of ANAX2 and lncRNA Fendrr were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Furthermore, Western blot analysis was performed to determine the protein levels of ANXA2, Bcl-2, and Bax. The association between lncRNA Fendrr and ANXA2 was disclosed by RNA pull-down, RNA immunoprecipitation, and electrophoretic mobility shift assays. RESULTS ANXA2 was elevated in caerulein-induced AP model and promoted apoptosis of AR42J cells. LncRNA Fendrr was also upregulated in AP cell model and directly bound ANXA2 protein. Further studies indicated that the interaction between ANXA2 and lncRNA Fendrr contributed to the apoptosis of AR42J cells in AP cell model. CONCLUSION Our study demonstrated that ANXA2 promoted AP progression via interacting with lncRNA Fendrr in vitro, which will provide a novel insight into the therapeutic target for AP.

Abstract
Background Competing endogenous RNAs (ceRNAs) are a newly identified type of regulatory RNA. Accumulating evidence suggests that ceRNAs play an important role in the pathogenesis of diseases such as cancer. Thus, ceRNA dysregulation may represent an important molecular mechanism underlying cancer progression and poor prognosis. In this study, we aimed to identify ceRNAs that may serve as potential biomarkers for early diagnosis of lung adenocarcinoma (LUAD). Methods We performed differential gene expression analysis on TCGA-LUAD datasets to identify differentially expressed (DE) mRNAs, lncRNAs, and miRNAs at different tumor stages. Based on the ceRNA hypothesis and considering the synergistic or feedback regulation of ceRNAs, a lncRNA–miRNA–mRNA network was constructed. Functional analysis was performed using gene ontology term and KEGG pathway enrichment analysis and KOBAS 2.0 software. Transcription factor (TF) analysis was carried out to identify direct targets of the TFs associated with LUAD prognosis. Identified DE genes were validated using gene expression omnibus (GEO) datasets. Results Based on analysis of TCGA-LUAD datasets, we obtained 2,610 DE mRNAs, 915 lncRNAs, and 125 miRNAs that were common to different tumor stages (|log2(Fold change)| ≥ 1, false discovery rate < 0.01), respectively. Functional analysis showed that the aberrantly expressed mRNAs were closely related to tumor development. Survival analyses of the constructed ceRNA network modules demonstrated that five of them exhibit prognostic significance. The five ceRNA interaction modules contained one lncRNA (FENDRR), three mRNAs (EPAS1, FOXF1, and EDNRB), and four miRNAs (hsa-miR-148a, hsa-miR-195, hsa-miR-196b, and hsa-miR-301b). The aberrant expression of one lncRNA and three mRNAs was verified in the LUAD GEO dataset. Transcription factor analysis demonstrated that EPAS1 directly targeted 13 DE mRNAs. Conclusion Our observations indicate that lncRNA-related ceRNAs and TFs play an important role in LUAD. The present study provides novel insights into the molecular mechanisms underlying LUAD pathogenesis. Furthermore, our study facilitates the identification of potential biomarkers for the early diagnosis and prognosis of LUAD and therapeutic targets for its treatment.

Abstract
This study was to investigate the biological function and underlying mechanisms of FENDRR in cholangiocarcinoma (CCA) cell proliferation, migration and invasion. FENDRR and survivin expression in CCA tissues or cell lines were measured by qRT-PCR. In QBC939 and HuCCTl cells, cell proliferation was detected by CCK-8, cell migration and invasion were using transwell assay. RNA pull-down and RIP assay were performed to determine whether FENDRR can combine with SETDB1 in CCA cell. The effect of SETDB1 on survivin and H3K9me1 expression in CCA cells were determined by western blotting. ChIP analysis was performed to analyze the combination of SETDB1 with survivin promoter in CCA cell. The effect of SETDB1 knockdown on survivin and H3K9me1 expression in CCA cells after transfection with FENDRR were determined by western blotting. The results showed that lncRNA FENDRR was downregulated in CCA tissues and cells, and was negatively correlated with survivin expression. Further investigation demonstrated that FENDRR represses CCA cell proliferation, migration and invasion through regulating survivin expression. FENDRR associated with SETDB1 and H3K9 to epigenetically silence survivin and then regulated cell proliferation, migration and invasion. These findings indicate an important role for FENDRR-survivin axis in CCA cell proliferation, migration and invasion, and reveal a novel epigenetic mechanism for survivin silencing. Our data indicated that FENDRR silences survivin via SETDB1-mediated H3K9 methylation, thereby represses CCA cell proliferation, migration and invasion.

Abstract
Background Emerging evidences have demonstrated that lncRNAs play vital roles in various pathological processes, including cancer. The lncRNA WT1 antisense RNA (WT1-AS) serves as a tumor suppressor in various cancers. Nevertheless, the expression and precise function of WT1-AS in cervical carcinoma still remain not yet investigated. The objective of our study was to explore the expression of WT1-AS and its biological roles in cervical cancer. Methods Differences in the lncRNA expression profiles between cervical cancer and adjacent normal tissues were assessed by lncRNA expression microarray analysis. The expression of p53 in cervical cancer cell was assessed by qRT-PCR and immunofluorescence assay. Loss-of-function studies were used to explore the effect of lncRNA WT1-AS on the growth and metastasis of cervical cancer cell in vitro and in vivo. Results Our results demonstrated that WT1-AS was remarkably down-regulated in cervical carcinoma. Functional assays proved that up-regulation of WT1-AS significantly suppressed cervical cancer cell proliferation, migration and invasion. In addition, the luciferase reporter assay identified that miR-330-5p was the target of WT1-AS. Moreover, tumor suppressor p53 was identified as the direct target of miR-330-5p and alternation of miR-330-5p/p53 axis reversed the effects of WT1-AS in cervical cancer cell. Conclusion Altogether, our findings suggested that WT1-AS was down-regulated in cervical carcinoma and WT1-AS suppressed cervical carcinoma cell- proliferation, migration and invasion through regulating the miR-330-5p/p53 axis.

Abstract
Autism spectrum disorder (ASD) is a set of complex neurodevelopmental disorders with etiology that remains elusive. Although there is a mounting body of investigation in different brain regions related to ASD, our knowledge about the common and distinct perturb condition between them is at the threshold of accumulation. In this study, based on protein-protein interactions, post-mortem transcriptome analysis was performed with corpus callosum (CC) and prefrontal cortex (PFC) samples from ASD individuals and controls. Co-expression network analysis revealed that a total of seven (four for CC set, three for PFC set) core dysfunctional modules strongly enriched for known ASD-risk genes. Three quarters of them in CC set (M4, M6, M29) significantly enriched for genes annotated by genetically associated variants in our previous whole genome sequencing data. We further determined transcriptional and post-transcriptional regulation subnetwork for each ASD-correlated module, including 47 pivot transcription factors, 130 pivot miRNAs, and 7 pivot lncRNAs. Moreover, there were significantly more interactions between CC-M4, -M6, and PFC-M2, mainly involved in synaptic functions and neuronal development. Our integrated multifactor analysis of ASD brain transcriptome profile illustrated underlying common and distinct molecular mechanisms and the module crosstalk between CC and PFC, helping to shed light on the molecular neuropathological underlying ASD.

Abstract
Long non-coding RNA FENDRR is implicated in progression of several cancers, but its exact role and mechanism in hepatocellular carcinoma (HCC) are largely unknown. In this study, we investigated the expression and biological roles of FENDRR in HCC tissues and cell lines. We found that the expression levels of FENDRR were significantly down-regulated in HCC tissues and cells. FENDRR overexpression could inhibit the growth of HCC cells in vitro and in vivo. Moreover, up-regulation of FENDRR suppressed the migration and invasion of HCC cells. Mechanistically, we demonstrated that FENDRR interacted directly with Glypican-3 (GPC3) promoter and methylated GPC3 promoter, which led to down-regulation of GPC3 expression. Ectopic expression of GPC3 ablated the inhibitory effects of FENDRR on HCC cell proliferation, migration and invasion. Taken together, we provided the first evidence for the inhibitory activity of FENDRR in HCC, which is causally linked to targeting GPC3 at the epigenetic level. Restoration of FENDRR may be a potential approach to prevent HCC progression and metastasis.

Abstract
Long intergenic non-coding RNAs (lincRNAs) are >200 nucleotides long non-coding RNAs, which have been shown to be implicated in carcinogenic processes by interacting with cancer associated genes or other non-coding RNAs. However, their role in development of rare gastrointestinal stromal tumors (GISTs) is barely investigated. Therefore, the aim of this study was to define lincRNAs deregulated in GIST and find new GIST-lincRNA associations. Next-generation sequencing data of paired GIST and adjacent tissue samples from 15 patients were subjected to a web-based lincRNA analysis. Three deregulated lincRNAs (MALAT1, H19 and FENDRR; adjusted p-value < 0.05) were selected for expression validation in a larger group of patients (n = 22) by RT-qPCR method. However, only H19 and FENDRR showed significant upregulation in the validation cohort (adjusted p < 0.05). Further, we performed correlation analyses between expression levels of deregulated lincRNAs and GIST-associated oncogenes or GIST deregulated microRNAs. We found high positive correlations between expression of H19 and known GIST related oncogene ETV1, and between H19 and miR-455-3p. These findings expand the knowledge on lincRNAs deregulated in GIST and may be an important resource for the future studies investigating lincRNAs functionally relevant to GIST carcinogenesis.

The Impact of lncRNA Dysregulation on Clinicopathology and Survival of Breast Cancer: A Systematic Review and Meta-analysis. MOLECULAR THERAPY. NUCLEIC ACIDS 2018; 12:359-369. [PMID: 30195774 PMCID: PMC6037885 DOI: 10.1016/j.omtn.2018.05.018] [Citation(s) in RCA: 59] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/23/2017] [Revised: 05/20/2018] [Accepted: 05/20/2018] [Indexed: 12/18/2022]
Abstract
Dysregulation of multiple long non-coding RNAs (lncRNAs) was reported to play major roles in breast cancer (BC). Here we aimed to collect most of the relevant literature to assess the prognostic value of lncRNAs in BC. To this end, we systematically searched PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure (CNKI), and Wanfang to identify published articles on the associations of lncRNAs with clinicopathology and/or survival of BC. Via this searching, we identified 70 articles involving 9,307 BC patients and regarding 48 lncRNAs. The expression of 41 lncRNAs was related to one or more clinicopathological parameters of BC, including tumor size; lymph node metastasis; histological grade; TNM stage; and estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2) statuses (p < 0.05). Dysregulation of 28 lncRNAs was associated with overall survival, and abnormal expression of 9 lncRNAs was linked to disease-free survival. Furthermore, the expression level of 3 lncRNAs was correlated with metastasis-free survival, 3 lncRNAs with relapse-free survival, and 3 lncRNAs with progression-free survival. Our analysis showed that multiple lncRNAs were significantly associated with BC clinicopathology and survival. A large-scale study is needed to verify the prognostic value of these lncRNAs in BC.
