Abstract
As microRNAs (miRNA) regulate almost all physiopathological activities in the human body, miRNA therapeutics that deliver miRNA regulators have attracted considerable attention in the field of nucleic acid drug development. The use of tetrahedral DNA nanostructures to deliver miRNA regulators is promising because of their simple fabrication, enhanced cell entry, effective tissue penetration, biocompatibility and functional editability. This protocol extension builds on our previous protocol for the use of tetrahedral DNA nanostructures and was designed to establish an updated bioswitchable delivery system (BDS) for achieving controlled cargo loading and release. A ribonuclease H-sensitive sequence is designed as a bioswitchable apparatus for the targeted release of the miRNA regulator. The functional sequence of the miRNA regulator and minimal secondary structure formation tendency during annealing are two key points in cargo design. We provide two BDS design strategies; BDS-A comprises an intact DNA tetrahedron with the RNA cargo hanging outside, offering the merits of lower cost, simplicity, and more direct structural design. In the BDS-B design, the RNA regulators are embedded into the DNA tetrahedron, which is beneficial for dermal tissue permeation applications. Following sequence design in Oligo 7 and Tiamat, the BDS assembly is completed and then ribonuclease H achieves controlled release of the miRNA regulator by triggering the bioswitchable apparatus. This is verified via polyacrylamide and agarose gel electrophoresis or fluorophore modifications. Both BDSs show promising cellular membrane permeability, tissue permeability and target inhibition in vitro and in vivo. The assembly and characterization of the BDS can be completed in 4 d, and the validation time for biostability and biological applications will depend on the specific use.

Abstract
The cell cycle comprises sequential events during which a cell duplicates its genome and divides it into two daughter cells. This process is tightly regulated to ensure that the daughter cell receives identical copied chromosomal DNA and that any errors in the DNA during replication are correctly repaired. Cyclins and their enzyme partners, cyclin-dependent kinases (CDKs), are critical regulators of G- to M-phase transitions during the cell cycle. Mitogenic signals induce the formation of the cyclin/CDK complexes, resulting in phosphorylation and activation of the CDKs. Once activated, cyclin/CDK complexes phosphorylate specific substrates that drive the cell cycle forward. The sequential activation and inactivation of cyclin-CDK complexes are tightly controlled by activating and inactivating phosphorylation events induced by cell-cycle proteins. The non-coding RNAs (ncRNAs), which do not code for proteins, regulate cell-cycle proteins at the transcriptional and translational levels, thereby controlling their expression at different cell-cycle phases. Deregulation of ncRNAs can cause abnormal expression patterns of cell-cycle-regulating proteins, resulting in abnormalities in cell-cycle regulation and cancer development. This review explores how ncRNA dysregulation can disrupt cell division balance and discusses potential therapeutic approaches targeting these ncRNAs to control cell-cycle events in cancer treatment.

Abstract
More and more evidence shows that long non-coding RNA (lncRNA) plays an important role in the biological behavior of many kinds of malignant tumors, but the specific function of lncRNA Linc00657 in cervical cancer is still unknown. The purpose of this study is to explore the effect of Linc00657 on the malignant progression of cervical cancer and its potential mechanism. In two kinds of cervical cancer cell lines and normal cervical epithelial cells, qRT-PCR showed increased expression of Linc00657 in cervical cancer cells. Through MTT, clone formation test, flow cytometry, wound healing test and Transwell test, it has been found that overexpression of Linc00657 could promote the proliferation,migration and invasion of cervical cancer cells,and inhibit apoptosis. Through the StarBase database, it was found that there may be a mutual regulatory relationship between Linc00657 and Skp2, and Skp2 may be the downstream target of Linc00657. QRT-PCR detection confirmed that the expression of Skp2 was increased in cervical cancer cells with overexpression of Linc00657. TIMER2 database found that Skp2 was associated with lipid metabolic enzymes and immune cell infiltration. It was found that Linc00657 knockdown inhibited tumor growth and metastasis and inhibited the expression of Skp2 in vivo. In short, our research shows that Linc00657 has carcinogenic properties in cervical cancer, and LINC00657 promotes the occurrence of cervical cancer by up-regulating the expression of Skp2. We predict that Linc00657/mir30s/Skp2 axis plays a role in the malignant progression of cervical cancer. In addition, Skp2 may participate in cancer immune response and promote lymph node metastasis of cervical cancer through lipid reprogramming. These findings also provide promising targets for the diagnosis and treatment of cervical cancer.

Abstract
Lung cancer, one of the most frequently diagnosed cancers, causes a huge number of mortalities globally. Among lung cancers, non-small cell lung cancer (NSCLC) is the most recorded. Despite accumulating research, the molecular basis of NSCLC progression remains poorly known. Therefore, we aim to assess the function of NCK1-AS1 in NSCLC and elucidate the molecular mechanism. Firstly, we quantified the NCK1-AS1 level in tumors and adjacent healthy tissues. NCK1-AS1 was significantly upregulated in NSCLC tumors, which was associated with poor prognosis in patients. Silencing NCK1-AS1 significantly inhibited the proliferation, migration, and invasion, as well as the EMT of NSCLC cell lines. Starbase bioinformatic prediction revealed that NCK1-AS1 targets miR-361-5p which acts to regulate ADAM10 gene expression. Our result showed that NCK1-AS1 upregulation markedly reduced miR-361-5p mRNA expression, while increasing ADAM10 expression. For the first time, we demonstrated that NCK1-AS1 regulates the miR-361-5p/ADAM10 axis, thereby promoting NSCLC progression. NCK1-AS1 might be developed as a therapeutic target for treating NSCLC.

Abstract
Cervical cancer is among the leading causes of cancer-associated mortality in women. In spite of vaccine availability, improved screening procedures, and chemoradiation therapy, cervical cancer remains the most commonly diagnosed cancer in 23 countries and the leading cause of cancer deaths in 36 countries. There is, therefore, a need to come up with novel diagnostic and therapeutic targets. Long non-coding RNAs (lncRNAs) play a remarkable role in genome regulation and contribute significantly to several developmental and disease pathways. The deregulation of lncRNAs is often observed in cancer patients, where they are shown to affect multiple cellular processes, including cell cycle, apoptosis, angiogenesis, and invasion. Many lncRNAs are found to be involved in the pathogenesis as well as progression of cervical cancer and have shown potency to track metastatic events. This review provides an overview of lncRNA mediated regulation of cervical carcinogenesis and highlights their potential as diagnostic and prognostic biomarkers as well as therapeutic targets for cervical cancer. In addition, it also discusses the challenges associated with the clinical implication of lncRNAs in cervical cancer.

Abstract
NCK1 Antisense RNA 1 (NCK1-AS1), alternatively named as NCK1-DT, is a long non-coding RNA (lncRNA) with important roles in the carcinogenesis. Multiple studies verified its oncogenic role in different types of cancer, including gastric cancer, non-small cell lung cancer, glioma, prostate cancer and cervical cancer. NCK1-AS1 functions as a sponge for several microRNAs, including miR-137, miR-22-3p, miR-526b-5p, miR-512-5p, miR-138-2-3p and miR-6857. In this review we present an outline of NCK1-AS1 function in malignant conditions as well as atherosclerosis.

Abstract
This study is designed to explore the role of long non-coding RNAs (lncRNAs) NCK1-AS1 in proliferative and invasive activities of esophageal squamous cell carcinoma (ESCC) cells by binding to microRNA-133b (miR-133b) to regulate ENPEP. Differentially expressed lncRNAs, miRs, genes and their targeting relationships were screened on ESCC-related gene expression datasets GSE17351 and GSE6188. The targeting relationships among NCK1-AS1, miR-133b, and ENPEP were verified using functional assays. Loss- and gain- of function assays were carried out to examine the roles of NCK1-AS1, miR-133b, and ENPEP in ESCC cell proliferative, invasive, migrative and apoptotic abilities as well as tumorigenesis in vivo. Elevated NCK1-AS1 and ENPEP but reduced miR-133b expression were found in ESCC. NCK1-AS1 knockdown or miR-133b overexpression inhibited the malignant properties of ESCC cells as well as tumorigenesis in vivo. NCK1-AS1 regulated the ENPEP expression by competitively binding to miR-133b. ENPEP overexpression reversed inhibition of NCK1-AS1 knockdown on the function of ESCC cells. This study provides evidence that silencing NCK1-AS1 inhibits expression of ENPEP by sponging miR-133b, thereby suppressing ESCC.

Abstract
Disease development requires the activation of complex multi-factor processes involving numerous long noncoding RNAs (lncRNAs), which describe non-protein-coding RNAs longer than 200 nucleotides. Emerging evidence indicates that lncRNAs act as essential regulators that perform pivotal roles in the pathogenesis and progression of human diseases. The mechanisms underlying lncRNA involvement in diverse diseases have been extensively explored, and lncRNAs are considered powerful biomarkers for clinical practice. The lncRNA noncatalytic region of tyrosine kinase adaptor protein 1 (NCK1) antisense 1 (NCK1-AS1), also known as NCK1 divergent transcript (NCK1-DT), is encoded on human chromosome 3q22.3 and produces a 27,274-base-long transcript. NCK1-AS1 has increasingly been characterized as a causative agent for multiple diseases. The abnormal expression and involvement of NCK1-AS1 in various biological processes have been associated with several diseases. Further exploration of the mechanisms through which NCK1-AS1 contributes to disease development and progression will provide a foundation for potential clinical applications of NCK1-AS1 in the diagnosis and treatment of various diseases. This review summarizes the current understanding of the various functions and mechanisms through which NCK1-AS1 contributes to various diseases and the clinical application prospects for NCK1-AS1.

Blood-derived deoxyribonucleic acid methylation clusters associate with adverse social exposures and endophenotypes of stress-related psychiatric illness in a trauma-exposed cohort of women. Front Psychiatry 2022; 13:892302. [PMID: 36405926 PMCID: PMC9668877 DOI: 10.3389/fpsyt.2022.892302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Accepted: 09/21/2022] [Indexed: 11/06/2022] Open
Abstract
Adverse social exposures (ASEs) such as low income, low educational attainment, and childhood/adult trauma exposure are associated with variability in brain region measurements of gray matter volume (GMV), surface area (SA), and cortical thickness (CT). These CNS morphometries are associated with stress-related psychiatric illnesses and represent endophenotypes of stress-related psychiatric illness development. Epigenetic mechanisms, such as 5-methyl-cytosine (5mC), may contribute to the biological embedding of the environment but are understudied and not well understood. How 5mC relates to CNS endophenotypes of psychiatric illness is also unclear. In 97 female, African American, trauma-exposed participants from the Grady Trauma Project, we examined the associations of childhood trauma burden (CTQ), adult trauma burden, low income, and low education with blood-derived 5mC clusters and variability in brain region measurements in the amygdala, hippocampus, and frontal cortex subregions. To elucidate whether peripheral 5mC indexes central nervous system (CNS) endophenotypes of psychiatric illness, we tested whether 73 brain/blood correlated 5mC clusters, defined by networks of correlated 5mC probes measured on Illumina's HumanMethylation Epic Beadchip, mediated the relationship between ASEs and brain measurements. CTQ was negatively associated with rostral middle frontal gyrus (RMFG) SA (β =-0.231, p = 0.041). Low income and low education were also associated with SA or CT in a number of brain regions. Seven 5mC clusters were associated with CTQ (pmin = 0.002), two with low education (pmin = 0.010), and three with low income (pmin = 0.007). Two clusters fully mediated the relation between CTQ and RMFG SA, accounting for 47 and 35% of variability, respectively. These clusters were enriched for probes falling in DNA regulatory regions, as well as signal transduction and immune signaling gene ontology functions. Methylome-network analyses showed enrichment of macrophage migration (p = 9 × 10-8), T cell receptor complex (p = 6 × 10-6), and chemokine-mediated signaling (p = 7 × 10-4) pathway enrichment in association with CTQ. Our results support prior work highlighting brain region variability associated with ASEs, while informing a peripheral inflammation-based epigenetic mechanism of biological embedding of such exposures. These findings could also serve to potentiate increased investigation of understudied populations at elevated risk for stress-related psychiatric illness development.

Abstract
The Cyclin-dependent kinase (CDK) class of serine/threonine kinases has crucial roles in the regulation of cell cycle transition and is mainly involved in the pathogenesis of cancers. The expression of CDKs is controlled by a complex regulatory network comprised of genetic and epigenetic mechanisms, which are dysregulated during the progression of cancer. The abnormal activation of CDKs results in uncontrolled cancer cell proliferation and the induction of cancer stem cell characteristics. The levels of CDKs can be utilized to predict the prognosis and treatment response of cancer patients, and further understanding of the function and underlying mechanisms of CDKs in human tumors would pave the way for future cancer therapies that effectively target CDKs. Defects in the regulation of cell cycle and mutations in the genes coding cell-cycle regulatory proteins lead to unrestrained proliferation of cells leading to formation of tumors. A number of treatment modalities have been designed to combat dysregulation of cell cycle through affecting expression or activity of CDKs. However, effective application of these methods in the clinical settings requires recognition of the role of CDKs in the progression of each type of cancer, their partners, their interactions with signaling pathways and the effects of suppression of these kinases on malignant features. Thus, we designed this literature search to summarize these findings at cellular level, as well as in vivo and clinical levels.

LncRNA FAM13A-AS1 Regulates Proliferation and Apoptosis of Cervical Cancer Cells by Targeting miRNA-205-3p/DDI2 Axis. JOURNAL OF ONCOLOGY 2022; 2022:8411919. [PMID: 35783157 PMCID: PMC9246599 DOI: 10.1155/2022/8411919] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Accepted: 06/02/2022] [Indexed: 11/17/2022]
Abstract
The aim of this study was to explore the function of long noncoding RNA (lncRNA) FAM13A-AS1 and its associated mechanism in cervical cancer. A total of 30 cervical cancer tissues and adjacent tissues were collected. Cervical cancer cell lines, including SiHa and HeLa, were transfected with constructs expressing LV-FAM13A-AS1, silencing RNA LV-siFAM13A-AS1, miRNA mimics, and miRNA inhibitors. RT-qPCR was used to detect the expression of FAM13A-AS1 in cervical cancer tissues, including SiHa, HeLa, and HUCEC cells. MTT, flow cytometry, and transwell assays were performed to explore the influence of FAM13A-AS1 on cervical cancer cell proliferation, apoptosis, invasion, and migration. A bioinformatics analysis and a dual-luciferase assay were carried to confirm the target relationship between FAM13A-AS1 or DDI2 and miRNA-205-3p. Finally, in vivo tumorigenesis experiments were performed in nude mice to explore the effect of FAM13A-AS1 expression on cervical cancer. Low FAM13A-AS1 expression and high miRNA-205-3p expression were observed in cervical cancer tissues and cell lines (SiHa and HeLa). Upregulating the expression of FAM13A-AS1 inhibited proliferation, migration, and invasion of SiHa and HeLa cells, while the apoptosis of SiHa and HeLa cells was increased. More importantly, LV-FAM13A-AS1 could improve tumor development in vivo. In addition, FAM13A-AS1 negatively regulated the expression of miRNA-205-3p, while miRNA-205-3p reduced DDI2 expression, and miRNA-205-3p mimic reversed the effects of FAM13A-AS1 overexpression in vitro. In conclusion, FAM13A-AS1 inhibits the progression of cervical cancer by targeting the miRNA-205-3p/DDI2 axis, suggesting that FAM13A-AS1 might be a potential target for cancer cell treatment.

Abstract
Cancer is the world's second largest cause of death. The most common cancer treatments are surgery, radiation therapy, and chemotherapy. Drug resistance, epithelial-to-mesenchymal transition (EMT), and metastasis are all pressing issues in cancer therapy today. Increasing evidence showed that drug-resistant and EMT are co-related with each other. Indeed, drug-resistant cancer cells possess enhanced EMT and invasive ability. Recent researches have demonstrated lncRNAs (long noncoding RNAs) are noncoding transcripts, which play an important role in the regulation of EMT, metastasis, and drug resistance in different cancers. However, the relationships among lncRNAs, EMT, and drug resistance are still unclear. These effects could be exerted via several signaling pathways such as TGF-β, PI3K-AKT, and Wnt/β-catenin. Identifying the crucial regulatory roles of lncRNAs in these pathways and processes leads to the development of novel targeted therapies. We review the key aspects of lncRNAs associated with EMT and therapy resistance. We focus on the crosstalk between lncRNAs and molecular signaling pathways affecting EMT and drug resistance. Moreover, each of the mentioned lncRNAs could be used as a potential diagnostic, prognostic, and therapeutic biomarker for cancer. Although, there are still many challenges to investigate lncRNAs for clinical applications.

Abstract
BACKGROUND Although long non-coding RNA (lncRNA) NCK1-AS1 plays important roles in human cancer, its function in atherosclerosis (AS) remains unclear. METHOD The expression of NCK1-AS1 in AS blood samples was detected by qRT-PCR. Oxidized low-density lipoprotein (ox-LDL) was used to construct the AS cell model, and quantitative real-time polymerase chain reaction (qRT-PCR) assay was used to evaluate NCK1-AS1 level. Cell phenotypes including proliferation and apoptosis were assessed by Cell Counting Kit-8 (CCK-8) assay and flow cytometer, respectively. The malondialdehyde level was measured to evaluate oxidative stress. The expression of apoptosis-related proteins was evaluated by western blot. The expression of inflammatory cytokines (IL-1β, IL-6 and TNK-α) was measured by qRT-PCR and ELISA assays. The relationship among NCK1-AS1, miR-1197 and COX10 was determined by bioinformatic analysis and luciferase reporter assay. RESULTS NCK1-AS1 was significantly upregulated in AS blood samples and ox-LDL stimulated vascular smooth muscle cells (VSMCs). Knockdown of NCK1-AS1 increased cell viability, reduced cell apoptosis and MDA level, and also inhibited the expression of inflammatory cytokines (IL-1β, IL-6 and TNK-α) in ox-LDL stimulated VSMCs. NCK1-AS1 could positively regulate COX10 expression by directly sponging miR-1197. Moreover, co-transfection of sh-NCK1-AS1 and miR-1197 inhibitor, or co-transfection of sh-NCK1-AS1 and pc-COX10 (COX10 overexpressing plasmid) obviously reduced cell viability, promoted cell apoptosis, and increased MDA level in VSMCs followed by ox-LDL treatment for 24 h compared to that in sh-NCK1-AS1 transfected VSMCs. CONCLUSION Our study revealed that knockdown of NCK1-AS1 attenuated the development of AS by regulating miR-1197/COX10 axis, suggesting that this lncRNA might be a potential therapeutic target for AS.

Abstract
A comprehensive study focusing on immune-related long non-coding RNAs (lncRNAs) in cervical cancer (CC) was performed. Through the integration of TCGA data, a total of 266 immune-related lncRNAs were obtained. We defined all samples as an entire set, and randomly divided them into train set and test set at a ratio of 1:1. Univariate, LASSO and multivariate Cox regression analyses were carried out based on train set for key lncRNAs (UBL7-AS1, AC083809.1, LIPE-AS1, PCED1B-AS1, ELFN1-AS1 and NCK1-DT) to construct a prognostic model, while the others were used for validation. The overall survival (OS) suggested that we may have longer survival expectations for patients classified into the low-risk group. The P values of risk score in univariate analysis and multivariate analysis were all less than 0.05, indicating the ability of risk score to independently assess the prognosis of patients. For clinical application, a nomogram with a high degree of agreement between the predicted curve and the actual curve was constructed. Subsequently, immune status and chemotherapy response were investigated in two prognostic subtypes. The associations between risk score and immune cell were estimated, in which CD8+ T cells showed the highest positive correlation and activated mast cell showed the highest negative correlation. In addition, checkpoint proteins (CTLA4, LAG3, PD-1, and TIGIT) showing negative correlation with risk score were found to be upregulated in low-risk group. A total of 3 chemotherapy drugs including paclitaxel, vinorelbine and methotrexate were considered effective in patients of high-risk group. Using 6 key immune-related lncRNAs, we identified two prognostic subtypes and provided new insights for CC immunotherapy.

Abstract
Liver-specific deficiency of B-cell receptor-associated protein 31 knockout mice (BAP31-LKO) and the littermates were injected with acetaminophen (APAP), markers of liver injury, and the potential molecular mechanisms were determined. In response to APAP overdose, serum aspartate aminotransferase and alanine aminotransferase levels were increased in BAP31-LKO mice than in wild-type controls, accompanied by enhanced liver necrosis. APAP-induced apoptosis and mortality were increased. Hepatic glutathione was decreased (1.60 ± 0.31 μmol/g tissue in WT mice vs. 0.85 ± 0.14 μmol/g tissue in BAP31-LKO mice at 6 h, p < 0.05), along with reduced glutathione reductase activity and superoxide dismutase; while malondialdehyde was significantly induced (0.41 ± 0.03 nmol/mg tissue in WT mice vs. 0.50 ± 0.05 nmol/mg tissue in BAP31-LKO mice for 6 h, p < 0.05). JNK signaling activation and APAP-induced hepatic inflammation were increased in BAP31-LKO mice. The mechanism research revealed that BAP31-deficiency decreased Nrf2 mRNA stability (half-life of Nrf2 mRNA decreased from ~1.3 h to ~40 min) and miR-223 expression, led to reduced nuclear factor erythroid 2-related factor 2 (Nrf2) signaling activation and antioxidant genes induction. BAP31-deficiency decreased mitochondrial membrane potentials, reduced mitochondria-related genes expression, and resulted in mitochondrial dysfunction in the liver. Conclusions: BAP31-deficiency reduced the antioxidant response and Nrf2 signaling activation via reducing Nrf2 mRNA stabilization, enhanced JNK signaling activation, hepatic inflammation, and apoptosis, amplified APAP-induced hepatotoxicity in mice.

Abstract
Despite the remarkable decrease in cervical cancer incidence due to the availability of the HPV vaccine and implementation of screening programs for early detection in developed countries, this cancer remains a major health problem globally, especially in developing countries where most of the cases and mortality occur. Therefore, more understanding of molecular mechanisms of cervical cancer development might lead to the discovery of more effective diagnosis and treatment options. Research on long noncoding RNAs (lncRNAs) demonstrates the important roles of these molecules in many physiological processes and diseases, especially cancer. In the present review, we discussed the significance of lncRNAs altered expression in cervical cancer, highlighting their roles in regulating highly conserved signaling pathways, such as mitogen-activated protein kinase (MAPK), Wnt/β-catenin, Notch, and phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) pathways and their association with the progression of cervical cancer in order to bring more insight and understanding of this disease and their potential implications in cancer diagnosis and therapy.

Abstract
Long noncoding RNAs (lncRNAs) exert crucial effects on the development of many malignancies, including gastric cancer. Herein, we investigated the role of lncRNA noncatalytic region of tyrosine kinase adaptor protein 1 (NCK1) divergent transcript (NCK1-DT, also known as NCK1-AS1) in gastric cancer. Reverse transcription quantitative polymerase chain reaction demonstrated that NCK1-AS1 exhibited high expression in gastric cancer tissues and cells. In vitro assays including MTT, colony formation, Transwell, wound healing and sphere formation assays indicated that NCK1-AS1 depletion inhibited cell proliferation, migration, invasion and stemness maintenance. Luciferase reporter and RIP assays suggested that NCK1-AS1 functioned as a competitive endogenous RNA (ceRNA) for miR-22-3p to positively modulate BCL9 expression. BCL9 was a target gene of miR-22-3p. According to western blot analysis and TOP/FOP flash assay, NCK1-AS1 activated the Wnt/β-catenin signaling via the miR-22-3p/BCL9 axis. Furthermore, rescue experiments verified that NCK1-AS1 affected cellular processes by activating the Wnt/β-catenin signaling pathway via the miR-22-3p/BCL9 axis. Tumor xenograft model validated that NCK1-AS1 promoted tumor growth in vivo via the Wnt/β-catenin signaling by upregulating BCL9 expression. Overall, NCK1-AS1 functions as an oncogene and promotes gastric cancer progression via the miR-22-3p/BCL9-Wnt/β-catenin signaling pathway.

Abstract
Background Long non-coding RNAs (lncRNAs) are vital regulators of gene expression and cellular processes in multiple cancers, including melanoma. Nevertheless, the function of lncRNA NCK1-antisense 1 (NCK1-AS1) in melanoma remains unknown. Methods RT-qPCR was used to analyze the expression of NCK1-AS1, microRNA-526b-5p (miR-526b-5p) and ADAM metallopeptidase domain 15 (ADAM15). Cell proliferation was determined by CCK-8, colony formation and EdU assays. Cell migration was assessed by transwell migration and wound healing assays. Mechanism experiments including luciferase reporter, RIP and RNA pull down assays were conducted to demonstrate the interactions between RNAs. Xenograft model was established to verify the function of NCK1-AS1 and miR-526b-5p in melanoma in vivo. Results NCK1-AS1 was overexpressed in melanoma cell lines and NCK1-AS1 knockdown hampers the proliferation and migration of melanoma cells. Besides, miR-526b-5p binds to NCK1-AS1 in melanoma and ADAM15 was validated as its downstream target. Further, the inhibitory effects of NCK1-AS1 knockdown on cell proliferation and migration in melanoma were reversed by the depletion of miR-526b-5p and further counteracted by ADAM15 knockdown. The growth of melanoma tumors was hindered by the down-regulation of NCK1-AS1 or up-regulation of miR-526b-5p. Conclusion NCK1-AS1 facilitates cell proliferation and migration in melanoma via targeting miR-526b-5p/ADAM15 axis.

Abstract
This paper aimed at investigating AS1 expression in prostate cancer (PCa) and its effects on the proliferation and invasion of prostate cancer cells (PCCs). The prostate tissues and the matched adjacent normal prostate tissues excised and preserved during radical prostatectomy in our hospital were collected. The LncRNA NCK1-AS1 expression was detected. PCa patients were followed up for three years to analyze their prognosis. The correlation of LncRNA NCK1-AS1 expression with clinicopathological features was analyzed. Human normal prostate cells and human PCCs were selected, in which LncRNA NCK1-AS1 expression was tested to screen and then transfect the cells. Cell proliferation, invasion and migration were detected. Cell cycles and apoptosis were analyzed. Compared with the adjacent normal tissues, LncRNA NCK1-AS1 was highly expressed in the prostate cancer tissues. Its expression was remarkably different in those with different stages of TNM and with lymphatic metastasis or not. The prognosis of patients with high LncRNA NCK1-AS1 expression was remarkably poorer than that of those with low expression. Compared with the human normal prostate cells, LncRNA NCK1-AS1 expression in the human PCCs remarkably rose, with the greatest difference in 22Rv1 cells. Compared with the Blank group, cell proliferation and the number of plate cloned cells remarkably reduced in the sh-NCK1-AS1 group. Additionally, in this group, the number of invasive and migratory cells remarkably reduced; the expression of invasion-related protein E-cadherin remarkably rose but that of MMP-2 remarkably reduced; cell cycles were arrested and the expression of cycle-related proteins (CDK4, CDK6, cyclin D1) remarkably reduced; the apoptotic rate and the expression of apoptosis-related protein Bax remarkably rose. LncRNA NCK1-AS1 is highly expressed in PCa, so its down-regulation can inhibit PCCs from proliferating and reduce the number of invasive cells.

OPINION STATEMENT Osteosarcoma (OS), the most common primary malignant bone tumor, is a vastly aggressive disease in children and adolescents. Although dramatic progress in therapeutic strategies have achieved over the past several decades, the outcome remains poor for most patients with metastatic or recurrent OS. Nowadays, conventional treatment for OS patients is surgery combined with multidrug chemotherapy including doxorubicin, methotrexate, and cisplatin (CDDP). In this sense, cisplatin (CDDP) is one of the most drugs used in the treatment of OS but drug resistance to CDDP appears as a serious problem in the use of this drug in the treatment of OS. Thus, we consider that the understanding the molecular mechanisms and the genes involved that lead to CDDP resistance is essential to developing more effective treatments against OS. In this review, we present an outline of the key role of the long non-coding RNAs (lncRNAs) in CDDP resistance in OS. This overview is expected to contribute to understand the mechanisms of CDDP resistance in OS and the relationship of the expression regulation of several lncRNAs.

Front Med (Lausanne) 2020; 7:608441. [PMID: 33344485 PMCID: PMC7746878 DOI: 10.3389/fmed.2020.608441] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Accepted: 10/26/2020] [Indexed: 02/06/2023] Open
Abstract
Background and Objective: Chemotherapy and radiotherapy are effective treatment options for cervical cancer (CC), but their efficacy is limited by short survival rate of about 5 years particularly for advance stage CC. Bioinformatics analysis combined with experimental in vivo and in vitro data can identify potential markers of tumorigenesis and cancer progression to improve CC prognosis and survival rate of the patients. This study aims to investigate the prognostic value of family with sequence similarity 83, member A (FAM83A) gene and miR-206 in promoting CC progression and the involved genetic signaling pathways. Method: This was a bioinformatic analysis study based on RNA sequencing data of The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases and verification by in vivo and in vitro experimental data. It was designed to evaluate whether the aberrantly expressed gene signatures could serve as new potential biomarker to improve prognosis prediction in CC. The TCGA RNA sequencing data [306 cervical squamous cell carcinoma (SCC) and endocervical adenocarcinoma samples and 13 adjacent samples] and GEO data (GSE9750 and GSE52903 datasets) were integrated and performed a bioinformatics analysis. Results: The results showed that CC-associated FAM83A gene serves as a key regulator of CC development and progression. Functionally, we observed that FAM83A is significantly overexpressed in CC, which is linked to poor overall survival as well as disease-free survival in CC patients. The in-vitro and in-vivo assessments performed after silencing FAM83A revealed that cell proliferation was significantly inhibited and the S-phase cell cycle arrest was induced. Mechanistically, FAM83A plays a role in PI3K/AKT signaling, and its downstream molecules could promote CC cell proliferation. Furthermore, functionality assessments by in-vitro luciferase reporter system and immunoblot analysis showed that miR-206 was the upstream of FAM83A and negatively correlated with FAM83A. Conclusion: The miR-206/FAM83A/PI3K/AKT signaling pathway possibly serves as a critical effector in CC progression indicating the potential prognostic value of FAM83A gene as a novel biomarker for CC progression.

Abstract
Significance: It is now clear that genetic changes underlie the basis of cancer, and alterations in functions of multiple genes are responsible for the process of tumorigenesis. Besides the classical genes that are usually implicated in cancer, the role of noncoding RNAs (ncRNAs) and reactive oxygen species (ROS) as independent entitites has also been investigated. Recent Advances: The microRNAs and long noncoding RNAs (lncRNAs), two main classes of ncRNAs, are known to regulate many aspects of tumor development. ROS, generated during oxidative stress and pathological conditions, are known to regulate every step of tumor development. Conversely, oxidative stress and ROS producing agents can suppress tumor development. The malignant cells normally produce high levels of ROS compared with normal cells. The interaction between ROS and ncRNAs regulates the expression of multiple genes and pathways implicated in cancer, suggesting a unique mechanistic relationship among ncRNA-ROS-cancer. The mechanistic relationship has been reported in hepatocellular carcinoma, glioma, and malignancies of blood, breast, colorectum, esophagus, kidney, lung, mouth, ovary, pancreas, prostate, and stomach. The ncRNA-ROS regulate several cancer-related cell signaling pathways, namely, protein kinase B (AKT), epidermal growth factor receptor (EGFR), forkhead box O3 (FOXO3), kelch-like ECH-associated protein 1 (Keap1), nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), nuclear factor erythroid 2-related factor 2 (Nrf2), p53, phosphatase and tensin homologue (PTEN), and wingless-related integration site (Wnt)/glycogen synthase kinase-3 beta (GSK3β). Critical Issues: To date, most of the reports about ncRNA-oxidative stress-carcinogenesis relationships are based on cell lines. The mechanistic basis for this relationship has not been completely elucidated. Future Directions: Attempts should be made to explore the association of lncRNAs with ROS. The significance of the ncRNA-oxidative stress-carcinogenesis interplay should also be explored through studies in animal models.

Abstract
Long noncoding RNAs (lncRNAs), once considered to be nonfunctional relics of evolution, are emerging as essential genes in tumor progression. However, the function and underlying mechanisms of lncRNAs in glioma remain unclear. This study aimed to investigate the role of LINC00998 in glioma progression. Through screening using TCGA database, we found that LINC00998 was downregulated in glioblastoma tissues and that low expression of LINC00998 was associated with poor prognosis. Overexpression of LINC00998 inhibited glioma cell proliferation in vitro and in vivo and blocked the G1/S cell cycle transition, which exerted a tumor-suppressive effect on glioma progression. Mechanistically, RNA pull-down and mass spectrometry results showed an interaction between LINC00998 and CBX3. IP assays demonstrated that LINC00998 could stabilize CBX3 and prevent its ubiquitination degradation. GSEA indicated that LINC00998 could regulate the c-Met/Akt/mTOR signaling pathway, which was further confirmed by a rescue assay using siRNA-mediated knockdown of CBX3 and the Akt inhibitor MK2206. In addition, dual-luciferase assays showed that miR-34c-5p could directly bind to LINC00998 and downregulate its expression. Our results identified LINC00998 as a novel tumor suppressor in glioma, and LINC00998 could be a novel prognostic biomarker, providing a strategy for precision therapy in glioma patients.

Abstract
Background Radiation resistance is a major obstacle to the prognosis of cervical cancer (CC) patients. Many studies have confirmed that long non-coding RNAs (lncRNAs) are involved in the regulation of radiosensitivity of cancers. However, whether small nucleolar RNA host gene 12 (SNHG12) regulates the radiosensitivity of CC remains unknown. Methods Quantitative real-time polymerase chain reaction was used to measure the expression levels of SNHG12 and microRNA-148a (miR-148a). The radiosensitivity of cells was evaluated by clonogenic assay. Flow cytometry and caspase-3 activity assay were performed to assess the apoptosis ability and cell cycle distribution of cells. Besides, dual-luciferase reporter and RNA immunoprecipitation assay were used to verify the interaction between miR-148a and SNHG12 or cyclin-dependent kinase 1 (CDK1). Also, the protein levels of CDK1, CCND1 and γ-H2AX were detected by western blot analysis. Furthermore, in vivo experiments were conducted to verify the effect of SNHG12 on CC tumor growth. Ki-67 and TUNEL staining were employed to evaluate the proliferation and apoptosis rates in vivo. The hematoxylin and eosin (HE) staining were employed to evaluate the tumor cell morphology. Results SNHG12 was upregulated in CC tissues and cells, and its knockdown improved the radiosensitivity by promoting the radiation-induced apoptosis and cell cycle arrest of CC cells. Also, miR-148a could be sponged by SNHG12 and could target CDK1. MiR-148a inhibitor or CDK1 overexpression could invert the promotion effect of silenced-SNHG12 on CC radiosensitivity. Meanwhile, SNHG12 interference reduced the tumor growth of CC, increased miR-148a expression, and inhibited CDK1 level in vivo. Conclusion LncRNA SNHG12 promoted CDK1 expression to regulate the sensitivity of CC cells to radiation through sponging miR-148a, indicating that SNHG12 could be used as a potential biomarker to treat the radiotherapy resistance of CC patients.

Abstract
BACKGROUND Bladder cancer (BC) is a common tumor in the urinary system with a high recurrence rate. The individualized treatment and follow-up after surgery is the key to a successful outcome. Currently, the surveillance strategies are mainly depending on tumor stage and grade. Previous evidence has proved that tumor grade was a significant and independent risk factor of BC recurrence. Exploring the grade-related genes may provide us a new approach to predict prognosis and guide the post-operative treatment in BC patients. METHODS In this study, the weighted gene co-expression network analysis was applied to identify the hub gene module correlated with BC grade using GSE71576. After constructing a protein-protein interaction (PPI) network with the hub genes inside the hub gene module, we identified some potential core genes. TCGA and another independent dataset were used for further validation. RESULTS The results revealed that the expression of AURKA, CCNA2, CCNB1, KIF11, TTK, BUB1B, BUB1, and CDK1 were significantly higher in high-grade BC, showing a strong ability to distinguish BC grade. The expression levels of the 8 genes in normal, paracancerous, tumorous, and recurrent bladder tissues were progressively increased. By conducting survival analysis, we proved their prognostic value in predicting the recurrence of BC. Eventually, we constructed a prognostic nomogram by combining the 8-core-gene panel with clinicopathologic features, which had shown great performance in predicting the recurrence of BC. CONCLUSION We identified 8 core genes that revealed a significant correlation with the tumor grade as well as the recurrence of BC. Finally, we proved the value of a novel prognostic nomogram for predicting the relapse-free survival of BC patients after surgery, which could guide their treatment and follow-up.

Abstract
Background Oral squamous cell carcinoma (OSCC) at early stages can be misdiagnosed as an oral ulcer (OU) due to similar symptoms, such as chronic and indurated ulcer. LncRNA NCK1-AS1 has been characterized as a key player in cervical cancer, while its role in OSCC is unknown. Methods All participants were selected at Jiangxi Province Tumor Hospital from December 2016 to December 2018. Expression levels of NCK1-AS1 and miR-100 in plasma from both OSCC and OU patients were measured by RT-qPCR. Diagnostic analysis was performed through ROC curve. Potential interactions between NCK1-AS1 and miR-100 were detected by cell transfection experiments. Cell invasion and migration were assessed by Transwell assays. Results The expression of NCK1-AS1 was upregulated in early-stage OSCC patients but not in OU patients. Upregulation of NCK1-AS1 distinguished OSCC patients from OU patients. The expression of miR-100 was inversely correlated with the expression of NCK1-AS1. Overexpression of NCK1-AS1 was followed by promoted OSCC cell invasion and migration. Overexpression of miR-100 did not affect the expression of NCK1-AS1 but inhibited the role of NCK1-AS1. Conclusions Therefore, NCK1-AS1 may promote the metastasis of OSCC by downregulating miR-100.

Abstract
Long noncoding RNAs (lncRNAs) have been shown to play important roles in carcinogenesis and progression. In this study, we mainly investigate the potential influence of lncRNA NCK1 antisense RNA 1 (NCK1-AS1) on the progression of non-small cell lung cancer (NSCLC). RT-PCR was performed to determine the expression of NCK1-AS1 and miR-137 in NSCLC specimens and cell lines. The clinical significance of NCK1-AS1 in 148 patients was analyzed statistically. The receiver operating characteristic (ROC) curve was performed to estimate the diagnostic value of NCK1-AS1 and miR-137. Regulatory effects of NCK1-AS1 on proliferative, colony formation abilities, metastasis and apoptosis of SK-MES-1 and H1299 cells were assessed through a series of functional experiments. RNA-pull down and Dual-Luciferase reporter assay was performed to verify the sponge effect of NCK1-AS1 on miR-137. We observed that NCK1-AS1 expression was upregulated, while miR-137 expression was down-regulated in NSCLC specimens and cell lines. Increased NCK1-AS1 expression was positively correlated with TNM stage and lymph node metastasis and poor clinical outcome. The diagnostic value of NCK1-AS1 and miR-137 expression was also confirmed. Functionally, knockdown of NCK1-AS1 suppressed the proliferation, migration and invasion of NSCLC cells, and promoted apoptosis. Moreover, NCK1-AS1 was able to adsorb miR-137 via a sponge effect. Overall, our findings suggested that NCK1-AS1 may be a candidate biomarker and a target for new therapies in NSCLC patients.

Abstract
OBJECTIVE This study aimed at probing into the effect of lncRNA NCK1-AS1 on proliferation, migration and invasion of non-small cell lung cancer (NSCLC) cells and its regulatory function on miR-512-5p/p21 molecular axis. METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was used to assess the expressions of NCK1-AS1 and miR-512-5p in NSCLC tissues and cell lines. The alterations of cell proliferation, migration, invasion and cell cycle were examined by cell counting kit-8 (CCK-8) assay, BrdU experiment, Transwell experiment and flow cytometry, respectively. The dual-luciferase reporter assay and RNA immunoprecipitation experiment were performed to validate the binding relationships between miR-512-5p and NCK1-AS1, and miR-512-5p the 3'UTR of p21 mRNA. Western blot was used to determine the effects of NCK1-AS1 and miR-512-5p on p21 protein expression. RESULTS NCK1-AS1 expression was up-regulated in NSCLC tissues and cells, and its high expression was correlated with shorter overall survival time and faster progression of patients. Overexpression of NCK1-AS1 promoted NSCLC cell proliferation, migration and invasion, and accelerated the cell cycle, whereas NCK1-AS1 siRNA inhibited these malignant biological behaviors, and arrested cell cycle. NCK1-AS1 could bind to miR-512-5p, p21 was verified as a target gene of miR-512-5p, and NCK1-AS1 could up-regulate the expression of p21 in NSCLC cells via repressing miR-512-5p expression. CONCLUSION NCK1-AS1 promotes NSCLC progression by regulating miR-512-5p/p21 molecular axis.

Abstract
Glioma is the deadliest disease in human central nerve system. Abnormal expression of long noncoding RNA (lncRNA) expression has been demontrated to be implicated in various cancers. The oncogenic role of lncRNA NCK1-AS1 has been validated in cervical cancer, wheras its role in glioma remians obscure. Our research findings suggested that NCK1-AS1 was upregulated in glioma tissues and cells. NCK1-AS1 deficiency hindered cell proliferation and enhanced cell apoptosis. Additionally, the chemoresistance and radioresistance of glioma cells were impaired by NCK1-AS1 depletion. Moreover, miR-22-3p, a downstream gene of NCK1-AS1, could weaken glioma cell chemoresistance and radioresistance. Similarly, IGF1R was the downstream target gene of miR-22-3p. Further mechanism and function assays demonstrated that NCK1-AS1 promoted glioma cell growth, chemoresistance and radioresistance via sponging miR-22-3p to upregulate IGF1R. Finally, the tumor facilitator function of NCK1-AS1 was also verified by in vivo experiments. Taken together, NCK1-AS1 contributes to glioma cell proliferation, radioresistance and chemoresistance via miR-22-3p/IGF1R ceRNA pathway, which might provide a new insight for improving the radiotherapy and chemotherapy treatments of glioma.

Abstract
Genome regions that do not for code for proteins are generally transcribed into long non-coding RNAs. Growing evidence reveals that lncRNAs, defined as transcripts longer than 200 nucleotides, are commonly deregulated in cervical malignancies. New sequencing technologies have revealed a complete picture of the composition of the human transcriptome. LncRNAs perform diverse functions at transcriptional, translation, and post-translational levels through interactions with proteins, RNA and DNA. In the past decade, studies have shown that lncRNAs participate in the pathogenesis of many diseases, including cervical cancer. Hence, illuminating the roles of lncRNA will improve our understanding of cervical cancer. In this work, we summarize the current knowledge on lncRNAs in cervical cancer. We describe the emerging roles of lncRNAs in cervical cancer, particularly in cancer progression, metastasis, treatment resistance, HPV regulation, and metabolic reprogramming. The great promises of lncRNAs as potential biomarkers for cervical cancer diagnosis and prognosis are also discussed. We discuss current technologies used to target lncRNAs and thus control cancers, such as antisense oligonucleotides, CRISPR-Cas9, and exosomes. Overall, we show that lncRNAs hold great potentials as therapeutic agents and innovative biomarkers. Finally, further clinical research is necessary to advance our understanding of the therapeutic value of lncRNAs in cervical cancer.

Abstract
Emerging evidence had highlighted that exosomes could mediate cell-cell communication in human cancerous development via transferring the various molecular cargos, including long non-coding RNA (lncRNA). Taurine up-regulated 1 (TUG1) was previously reported as an oncogenic lncRNA in cervical cancer (CC) via facilitating cell proliferation and other vital biological behaviors. Nevertheless, the presence of TUG1 in exosomes and the functional regulation of exosomal TUG1 in CC are still elusive. The current study aimed at the communication between CC cell lines and endothelial cell-mediated by exosomes, as well as the roles of exosomes derived from CC cells and exosomal TUG1 in affecting angiogenesis. Initially, it was found that TUG1 expression was upregulated in both CC cells and their secreted exosomes. TUG1 was transferred from CC cells to recipient human umbilical vein endothelial cells (HUVECs) in the exosomes way. Interestingly, TUG1 depletion impaired the exosomes-mediated proangiogenic potential of HUVECs by modulating certain key angiogenesis-related genes. In addition, exosomal TUG1 contributed to HUVECs proliferation through suppressing caspase-3 activity and impacting apoptosis-related proteins. Collectively, we identified a new exosomes-mediated molecular mechanism by which CC cells transferred TUG1 via exosomes to recipient HUVECs, thus promoting angiogenesis, providing a promising target for early diagnosis of CC.

Abstract
Long noncoding RNA SBF2 antisense RNA 1 (lncRNA SBF2-AS1) has been reported to be involved in non-small-cell lung cancer (NSCLC) tumorigenesis. However, the biological role and regulatory mechanism of lncRNA SBF2-AS1 on NSCLC metastasis remain largely unknown. In this study, the expression level and functional role of SBF2-AS1 were investigated in both NSCLC tissues and cell lines. We found that SBF2-AS1 was upregulated in both NSCLC tissues and cell lines. Patients with high levels of SBF2-AS1 have larger tumors, higher malignancy, and poor prognosis. Knockdown of SBF2-AS1 significantly inhibited tumor growth in vivo and cell proliferation, migration, and invasion in vitro. Moreover, bioinformatics analysis, chromatin immunoprecipitation assay, and luciferase reporter assay proved that the upregulation of SBF2-AS1 was mediated by transcription factor E2F1. Further experiments demonstrated that miR-362-3p had complementary binding site with 3'-UTR of SBF2-AS1. Besides, luciferase reporter assay validated that GRB2 was the target protein of miR-362-3p. Rescue experiments showed that SBF2-AS1 silencing inhibited cell invasion and migration, while cotransfection si-SBF2-AS1 and miR-362-3p inhibitor rescued the effect of si-SBF2-AS1. These results demonstrate that E2F1-induced overexpression of SBF2-AS1 promotes the expression of GRB2 by targeting miR-362-3p to facilitate the metastasis of NSCLC.

Pathol Res Pract 2020; 216:152994. [PMID: 32402537 DOI: 10.1016/j.prp.2020.152994] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2020] [Revised: 04/01/2020] [Accepted: 04/22/2020] [Indexed: 12/24/2022]
Abstract
Accumulating evidence has supported the concept that long noncoding RNAs (lncRNAs) participate in the initiation and progression of human cervical cancer (CC). The long intergenic nonprotein-coding RNA 173 (LINC00173) is a recently identified cancer-associated factor. However, the expression and biological role of LINC00173 in CC are poorly understood. Here, for the first time, we found that the expression of LINC00173 was decreased in CC tissues compared with that in nontumor tissues. Data from The Cancer Genome Atlas (TCGA) further revealed that the downregulated expression of LINC00173 in CC tissues was correlated with poor survival. Functionally, LINC00173 overexpression suppressed HeLa cell proliferation via induction of G0/G1 phase arrest. Ectopic expression of LINC00173 also repressed the invasiveness of HeLa cells. Conversely, LINC00173 depletion resulted in the enhanced proliferation and invasiveness of C33A cells. Mechanistically, LINC00173 functioned as a molecular sponge for miR-182-5p and inversely regulated the miR-182-5p level in CC cells. F-box and WD repeat domain-containing 7 (FBXW7) was identified as the target of miR-182-5p. LINC00173 overexpression enhanced the FBXW7 level via regulation of miR-182-5p in HeLa Cells. More importantly, the inhibitory effects of LINC00173 on HeLa cell proliferation and invasiveness were reversed by FBXW7 silencing. Taken together, the results indicate that the LINC00173/miR-182-5p/FBXW7 axis is critical for CC progression, which might offer new insights into effective therapy for CC.

Abstract
BACKGROUND Glioma is a common brain malignancy with high mortality. The competing endogenous RNA (ceRNA) networks may play key roles in cancer progression. This study was conducted to probe the role of long noncoding RNA (lncRNA) NCK1-AS1 in glioma progression and the involved mechanisms. METHODS Microarray analyses were performed to explore the lncRNAs/miRNAs/genes with differential expression in glioma. NCK1-AS1 levels in glioma tissues and normal brain tissues, and in glioma cell lines and normal human glial cells were identified. The interactions among NCK1-AS1, miR-138-2-3p and TRIM24 were validated through luciferase reporter, RNA immunoprecipitation and RNA pull-down assays. Gain- and loss-of functions of NCK1-AS1, miR-138-2-3p and TRIM24 were performed to identify their roles in the behaviors of glioma cells. The activity of the Wnt/β-catenin pathway was measured. In vivo experiments were performed as well. RESULTS High expression of NCK1-AS1 was found in glioma tissues and cells, especially in U251 cells. Online predictions and the integrated experiments identified that NCK1-AS1 elevated the TRIM24 expression through sponging miR-138-2-3p, and further activated the Wnt/β-catenin pathway. Artificial silencing of NCK1-AS1 or up-regulation of miR-138-2-3p led to inhibited proliferation, invasion and migration but promoted cell apoptosis of U251 cells, while up-regulation of TRIM24 reversed these changes, and it activated the Wnt/β-catenin pathway. The in vitro results were reproduced in in vivo experiments. CONCLUSIONS Our study suggested that NCK1-AS1 might elevate TRIM24 expression and further activate the Wnt/β-catenin pathway via acting as a ceRNA for miR-138-2-3p. Silencing of NCK1-AS1 might inhibit the progression of glioma.

Abstract
Cervical cancer (CC) holds the second highest incidence and is the fourth dominating cause of cancer-induced death in women. It has been widely accepted that long noncoding RNAs (lncRNAs) are implicated in pathological and physiological activities of CC. However, the research of lncRNAs is still in the initial stage. The biological function of lncRNA deoxyguanosine kinase antisense RNA 1 (DGUOK-AS1) in human cancers has not been reported yet. We found that DGUOK-AS1 was aberrantly upregulated in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) tissues through TCGA database. Real-time quantitative polymerase chain reaction (RT-qPCR) also verified the high expression of DGUOK-AS1 in CC cell lines. Loss-of-function assays indicated that DGUOK-AS1 silence repressed CC cell growth. In addition, dual-luciferase reporter and RNA immunoprecipitation (RIP) experiments validated the binding relation between miR-653-5p and DGUOK-AS1 or EMSY. Results of the rescue assays elucidated that EMSY overexpression or miR-653-5p downregulation reversed the suppressive function of DGUOK-AS1 knockdown on cell growth and DNA repair in CC. To sum up, this research highlighted that DGUOK-AS1 could promote CC cell proliferation via serving as a ceRNA of miR-653-5p to release EMSY, which might inspire us to discover novel strategies for CC treatment. SIGNIFICANCE OF THE STUDY: DGUOK-AS1 knockdown hinders proliferation of CC cells. DGUOK-AS1 sequesters miR-653-5p to elevate EMSY in CC. EMSY is required for DGUOK-AS1 to induce cell proliferation and repress DNA damage in CC.

Abstract
BACKGROUND Long noncoding RNAs (lncRNAs) play critical and complex roles in regulating various biological processes of cancers. Our study aimed to investigate the involvement of lncRNA NCK1-AS1 in urinary bladder cancer (UBC). METHODS qRT-PCR was used to detect the expression of lncRNA NCK1-AS1 and miR-143 in UBC tissues and cells. The dual-luciferase reporter system assays were used to confirm the interaction between NCK1-AS1 and miR-143, and flow cytometry assays were applied to examine the behavioral changes in HT-1376 and HT-1197 cell lines. RESULTS It was observed that NCK1-AS1 was up-regulated, while miR-143 was down-regulated in tumor tissues than in adjacent healthy tissues of urinary bladder cancer (UBC) patients. A 5-year survival analysis showed that the survival rate of patients with high NCK1-AS1 level or low miR-143 level in tumor tissues appears relatively low. Correlation analysis revealed a significant inverse correlation between NCK1-AS1 and miR-143 in tumor tissues. Over-expression NCK1-AS1 reduced the expression level of miR-143, while elevating the level of miR-143 failed to affect NCK1-AS1 expression. NCK1-AS1 over-expression led to promoted proliferation and increased percentage of CD133+ (stemness) cells. CONCLUSION Therefore, NCK1-AS1 promotes cancer cell proliferation and increases cell stemness in UBC patients by down-regulating miR-143.

Abstract
Introduction The present study was carried out to explore the functionality of lncRNA NCK1-AS1 in nasopharyngeal carcinoma (NPC). Methods Levels of NCK1-AS1 were measured by performing qPCR and were compared by ANOVA (one-way) performed in combination with Tukey's test. Expression levels of miR-135a in plasma of NPC patients were measured by performing qPCR. The effects of transfections on the invasion and migration of C666-1 cells were analyzed by Transwell assays. Results and discussion In the present study, we found that the plasma levels of NCK1-AS1 were significantly higher in NPC patients than the levels in patients with arthritis of the temporomandibular joint (TMJ), as well as healthy participants. No significant difference in plasma levels of NCK1-AS1 was found between TMJ patients and healthy participants. Upregulation of NCK1-AS1 distinguished NPC patients from TMJ patients and healthy participants. A significant and inverse correlation between NCK1-AS1 and miR-135a was found in NPC patients. NCK1-AS1 siRNA silencing led to the upregulation of miR-135a. NCK1-AS1 siRNA silencing and miR-135a overexpression resulted in inhibited cell migration and invasion, and miR-135a inhibition attenuated the effects of NCK1-AS1 siRNA silencing. Conclusion The downregulation of lncRNA NCK1-AS1 inhibited cancer cell migration and invasion in NPC by upregulating miR-135a.

Abstract
Purpose Long non-coding RNAs (lncRNAs) have been proved to act crucial parts in the progress of human tumor. However, the role of lncRNAs in drug resistance of tumor cells remains to be further elucidated. The present study aimed to explore whether lncRNA NCK-AS1 could affect the cisplatin (DDP) resistance in human osteosarcoma cell and the underlying molecular mechanism. Methods The expression of NCK1-AS1 and miR-137 in osteosarcoma cells was detected by qRT-PCR. CCK-8 assay, colony formation assay, Western blotting, wound healing assay and transwell assay were employed to assess the cell proliferation, migration and invasion. In addition, CCK-8 assay, flow cytometry, qRT-PCR and resistance gene activity analysis were performed to assess the DDP sensitivity of osteosarcoma cells. The interaction between NCK1-AS1 and miR-137 was identified using a dual-luciferase reporter gene assay and RNA immunoprecipitation (RIP) assay. Results The results revealed that NCK1-AS1 was significantly upregulated in osteosarcoma cells, as well as in DDP-resistant osteosarcoma cells. NCK1-AS1 silence inhibited the proliferation, migration and invasion of osteosarcoma cells, whereas enhanced the sensitivity of osteosarcoma cells to DDP. Furthermore, NCK1-AS1 directly interacted with miR-137 and overexpression of miR-137 suppressed the proliferation, migration and invasion of osteosarcoma cells. Most importantly, miR-137 overexpression enhanced the sensitivity of osteosarcoma cells to DDP, and high expression of NCK1-AS1 reversed the influences of miR-137 overexpression on DDP-resistant cells. Conclusion In short, NCK1-AS1 knockdown enhanced DDP sensitivity of osteosarcoma cells by regulating miR-137, which may be a novel potential target for anti-DDP resistance in human osteosarcoma.

Abstract
Background: Glioma is a common malignant tumor. The purpose of this study was to investigate the effect and molecular mechanism of long noncoding RNA (lncRNA) NCK1-AS1 on the drug resistance of temozolomide (TMZ) in glioma cells. Methods: The fresh and recurrent glioma tissues and peritumoral brain edema (PTBE) were collected from the same patient. U251 and A172 cells were treated with TMZ to screen TMZ-resistant cells. The expression levels of NCK1-AS1, miR-137, or TRIM24 were detected by quantitative real-time polymerase chain reaction (qRT-PCR), Western blotting, in situ hybridization (ISH), or RNA pull-down assay. Cell viability was measured by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazoliumbromide (MTT) assay. In addition, the relationship between NCK1-AS1 and miR-137 or TRIM24 and miR-137 was confirmed by dual luciferase activity assay. Results: NCK1-AS1 expression was increased in regular and recurrent glioma tissues and TMZ-resistant cells. Cell viability was increased in TMZ-resistant cells, and the IC50 of TMZ also increased in TMZ resistant cells. However, knockdown of NCK1-AS1 inhibited these increases. Moreover, suppression of NCK1-AS1 increased miR-137 expression, whereas overexpression of miR-137 decreased TRIM24 expression. Then, expression of miR-137 alleviated the NCK1-AS1 overexpression-induced increased expression of TRIM24. In addition, the decreases of cell viability and IC50 induced by NCK1-AS1 knockdown were reversed after adding TRIM24 in U251/TMZ and A172/TMZ cells. Conclusion: NCK1-AS1 could increase drug resistance of glioma cells to TMZ by modulating miR-137/TRIM24 pathway.

Abstract
Long non-coding (lnc)RNA NCK1 antisense RNA 1 (NCK1-AS1) has been characterized as an oncogene in cervical cancer, while its role in prostate cancer (PC) remains unknown. It was revealed in the present study that plasma NCK1-AS1 was upregulated in patients with PC when compared with patients with benign prostatic hyperplasia (BPH) and healthy controls. Upregulation of NCK1-AS1 distinguished patients with PC from patients with BPH and healthy controls. Overexpression of NCK1-AS1 led to significantly upregulated transforming growth factor (TGF)-β1, while TGF-β1 overexpression failed to significantly affect NCK1-AS1 in PC cells. NCK1-AS1 overexpression led to promoted migration and invasion. TGF-β inhibitor played an opposite role and attenuated the effects of NCK1-AS1 overexpression. Therefore, NCK1-AS1 may upregulate TGF-β1 to promote PC.

Abstract
Long non-coding RNA NCK1-antisense 1 (AS1) has recently been demonstrated to promote cell proliferation and induce cell cycle progression through the crosstalk NCK1-AS1/microRNA (miR)-6857/cyclin dependent kinase 1 pathway in cervical cancer. However, the regulatory mechanism of NCK1-AS1 in cervical cancer growth and metastasis remains largely unclear. In the present study, it was identified that NCK1-AS1 was significantly upregulated in cervical cancer tissues compared with the levels in adjacent non-tumour tissues. High expression levels of NCK1-AS1 were associated with tumour progression and poor prognosis in patients with cervical cancer. Silencing of NCK1-AS1 expression significantly decreased the levels of proliferation and migration of cervical cancer cells, and decreased the protein expression levels of matrix metalloproteinase (MMP)-2 and MMP-9. The results of the luciferase reporter gene assay indicated that there was an miR-134 binding site within the NCK1-AS1 gene in cervical cancer cells. miR-134 was significantly downregulated in cervical cancer tissues compared with the miR-134 levels in adjacent non-tumour tissues, and the expression level of miR-134 was inversely correlated with the NCK1-AS1 expression levels in cervical cancer tissues. Knockdown of miR-134 attenuated the inhibitory effects of NCK1-AS1 downregulation on the proliferation and migration of cervical cancer cells. Therefore, the data from the present study suggested that NCK1-AS1 serves a promotive role in cervical cancer cell proliferation and migration by functioning as a molecular sponge for miR-134. NCK1-AS1 may become a novel therapeutic target for cervical cancer.

Abstract
Background: Epigenetic regulation has been verified as a key mechanism in tumorigenesis. SET and MYND domain-containing protein 3 (SMYD3), a histone methyltransferase, is a promising epigenetic therapeutic target and is overexpressed in numerous human tumors. SMYD3 can promote oncogenic progression by methylating lysines to integrate cytoplasmic kinase signaling cascades or by methylating histone lysines to regulate specific gene transcription. However, the exact role of SMYD3 in the progression of ovarian cancer is still unknown. Methods: Immunohistochemistry was employed to test SMYD3 expression in ovarian cancer tissues from clinical patients. CCK-8 assay, Real-time cell analysis (RTCA), colony formation assay, cell cycle and apoptosis tested by Flow cytometer were employed to test the effects of SMYD3 on cell proliferation and apoptosis in ovarian cancer cell lines. A PCR array was used to identify the downstream targets of SMYD3. And, PCR and Western blot were used to verify their expression. The binding of SMYD3 on the promoter of target genes were tested by ChIP assays. We also use nude mice subcutaneous tumor model and patient-derived xenograft (PDX) model to investigate the tumor promotive function of SMYD3 in vivo. Results: SMYD3 expression was higher in ovarian cancer tissues and cell lines than in normal ovarian epithelial tissue and human ovarian surface epithelial cells (HOSEpiC). After silencing SMYD3, the proliferation of ovarian cancer cells was significantly inhibited in vitro. In addition, the SMYD3-specific small-molecule inhibitor BCI-121 suppressed ovarian cancer cell proliferation. Downregulation of SMYD3 led to S phase arrest and increased the cell apoptosis rate. Furthermore, a PCR array revealed that SMYD3 knockdown caused the upregulation of the cyclin-dependent kinase (CDK) inhibitors CDKN2A (p16INK4), CDKN2B (p15INK4B), CDKN3 and CDC25A, which may be responsible for the S phase arrest. In addition, the upregulation of CD40LG and downregulation of BIRC3 may explain the increased cell apoptosis rate after silencing SMYD3. We also discovered that SMYD3 bound on the promoter of CDKN2A and down-regulated its expression by triple-methylating H4K20. In addition, SMYD3 bound on the promoter of BIRC3 and up-regulated its expression by triple-methylating H3K4. Finally, knocking down SMYD3 could inhibit ovarian cancer growth in nude mice subcutaneous tumor model and PDX model. Conclusion: Our results demonstrated that SMYD3 was overexpressed in ovarian cancer and contributes to the regulation of tumor proliferation and apoptosis via SMYD3-H4K20me3-CDKN2A pathway and SMYD3-H3K4me3-BIRC3 pathway. Thus, SMYD3 is a promising epigenetic therapeutic target for ovarian cancer.

Abstract
Breast cancer (BRCA) is the most common type of cancer in adult females. Estrogen receptor (ER)+/progesterone receptor (PR)+, human epidermal-growth factor receptor 2 (HER2)− BRCA and triple-negative breast cancer (TNBC) are two important subtypes of this disease. Long non-coding RNA (lncRNA)-mediated transcriptional dysregulation triplets (lncTDTs) may contribute to the development of cancer; however, the precise functional roles of lncTDTs in ER+/PR+, HER2− BRCA and TNBC require further investigation. In the present study, an integrated and computational approach was conducted to identify lncTDTs based on transcription factor (TF), gene, lncRNA expression profiles and experimentally verified TF-gene interactions. The regulatory patterns of these lncTDTs are complex and differed in ER+/PR+, HER2− BRCA and TNBC. Of note, five common lncTDTs were reported for these BRCA subtypes. Functional analysis revealed lncTDTs to be enriched in the PI3K/AKT signaling pathway within the two BRCA subtypes. Additionally, certain lncTDTs were associated with survival and may be considered candidate prognostic biomarkers for BRCA subtypes. Collectively, the results of the present study provide novel insight into the functions and mechanisms of lncRNAs in ER+/PR+, HER2− BRCA and TNBC, and may aid the development of targeted treatments against certain subtypes of BRCA.

Abstract
Emerging evidence has indicated that microRNAs (miRNAs) play an important role in cervical cancer (CC). However, the role of miRNA (miR)‐665 in cervical cancer remains unclear. The aim of the present study was to investigate the potential functions of miR‐665 in CC and to identify the underlying mechanisms of action. Herein, we show that miR‐665 was downregulated in CC tissues and cell lines, which is negatively correlated with tumor size, distant metastasis, advanced TNM stage and poor prognosis. Functionally, miR‐665 inhibited cell proliferation, migration and invasion and resistance of cisplatin for CC cells, as well as tumor growth. We validated that transforming growth factor beta receptor 1 (TGFBR1) was a direct target of miR‐665 and mediated the ERK/SMAD pathway. In addition, we identified miR‐665 as the competing endogenous RNA for long noncoding (lnc)‐DANCR. These observations suggested that lnc‐DANCR‐mediated miR‐665 downregulation regulates the malignant phenotype of CC cells by targeting TGFBR1 through the ERK/SMAD pathway, which may present a pathway for novel therapeutic stratagems for CC therapy.

Abstract
Cervical cancer is the most common and lethal gynaecological tumor. Long noncoding RNAs (lncRNAs) have critical roles in various cancers, including cervical cancer. However, few studies investigated the diagnostic value of lncRNAs for cervical cancer. In this study, we investigated the expression pattern of a recently identified lncRNA GIHCG in cervical cancer tissues, cell lines, and serums by qRT-PCR. Furthermore, we explored the roles of GIHCG in cervical cancer using gain-of-function and loss-of-function assays. Our results revealed that GIHCG is up-regulated in cervical cancer tissues and cell lines compared with adjacent normal tissues and normal cervical epithelial cell line, respectively. Furthermore, serum GIHCG is significantly up-regulated in cervical cancer patients compared with healthy controls. ROC curve analysis revealed that serum GIHCG could accurately discriminate cervical cancer patients from healthy controls. Functionally, we found that overexpression of GIHCG promotes cell proliferation, inhibits cell apoptosis, and promotes cell migration of cervical cancer cells. Conversely, depletion of GIHCG inhibits cell proliferation, induces cell apoptosis, and inhibits cell migration of cervical cancer cells. Mechanistically, we found that GIHCG represses the expression of miR-200b. The expression of miR-200b is inversely correlated with the expression of GIHCG in cervical cancer tissues. Moreover, overexpression of miR-200b attenuates the roles of GIHCG in promoting cervical cancer tumor growth in vivo. In summary, this study demonstrated that GIHCG functions as an oncogene in cervical cancer via repressing miR-200b. This study also suggested that GIHCG may be a non-invasive diagnostic biomarker and a potential therapeutic target for cervical cancer.

Abstract
OBJECTIVE The study was to explore the roles of Nck1 in the angiogenesis of cervical squamous cell carcinoma (CSCC). METHODS mRNA and protein levels were evaluated with real-time quantitative PCR and immunohistochemisty/western blotting respectively. The cancer microvessel density (MVD) was assayed with CD34 endothelial labeling. Nck1 gene knock-in (SiHa-Nck1+) and knock-down (SiHa-Nck1-) were achieved by gene transfection and siRNA respectively. Protein level from cellular supernatant was measured with ELISA. Proliferation, migration and tube formation of the Human Umbilical Vein Endothelial cells (HUVECs) were evaluated by CCK-8 cell viability assay, transwell chamber assay and in vitro Matrigel tubulation assay respectively. RESULTS Nck1 level gradually increased from normal cervical epithelia to high-grade CIN, overexpressed in CSCC and was associated with cancer MVD. The ability of proliferation, migration and tube formation of HUVECs was enhanced in SiHa-Nck1+-treated while decreased in SiHa-NcK1--treated cells compared to SiHa-control-treated cells. Mechanistically, RAC1-GTP, p-PAK1 and MMP2 were increased in SiHa-NCK1+ cells and pretreatment with the Rac1 inhibitor (NSC23766) significantly decreased their levels. Furthermore, inhibition of PAK1 reduced MMP2 level in SiHa-Nck1+ cells whereas the level of Rac1-GTP was unaltered. Also, inhibition of Rac1 or PAK1 impaired angiogenesis-inducing capacity of cancer cells. CONCLUSIONS Nck1 promotes the angiogenesis-inducing capacity of CSCC via the Rac1/PAK1/MMP2 signal pathway.
