Objective: In this study, we explored the NPC-specific expression of ZFAS1 and the mechanism of ZFAS1-mediated growth, aggressiveness and tumorigenesis in NPC. Methods:The expression profile of lncRNAs was detected in NPC tissues and matching para-carcinoma tissues using microarray analysis. LncRNA-miRNA and miRNA-mRNA interaction networks were constructed using the miRcode v11 and TargetScanHuman v7.2 web server and then validated using dual-luciferase assay.Western blot and RT-qPCR were performed to detect protein and RNA expression.The effects of ZFAS1, miR-892b and LPAR1 dysregulation on the proliferative, migratory and invasive abilities of NPC cells were observed using colony formation, cell counting kit-8 (CCK-8) and transwell assays in vitro. In vivo, a xenograft nude mouse model was established to detect the impact of ZFAS1 dysregulation on the tumorigenicity of NPC cells. Results:The expression of multiple lncRNAs, of which ZFAS1 was up-regulated, was dysregulated in NPC tissues. ZFAS1 directly targeted miR-892b, and miR-892b negatively regulated the expression of downstream LPAR1. The proliferation, migration and invasion of NPC cells could be largely enhanced by the downregulation of miR-892b as well as the up-regulation of ZFAS1 and LPAR1, while the overexpression of miR-892b and the downregulation of ZFAS1 and LPAR1 decreased these abilities.In nude mice, the growth of tumour xenografts formed by HONE1 cells was significantly suppressed when ZFAS1 was silenced. Conclusion:The study demonstrated that lncRNA ZFAS1 may act as a promoter of tumorigenesis and metastasis in nasopharyngeal carcinoma, by up-regulating the expression of LPAR1 in a miR-892b-dependent manner.

“…Nevertheless, the mechanism of MEG3 as a tumor suppressor warrants further studies. LncRNA-LET, a recently identified 1ncRNA, has also been shown to act as a tumor suppressor in NPC as well [54, 55]. LET inhibited proliferation, adhesion and invasion of NPC in vitro by enhancing its expression.…”

“…LET inhibited proliferation, adhesion and invasion of NPC in vitro by enhancing its expression. By contrast, decreased LET expression could promote the proliferation, adhesion and invasion of NPC [55]. The reduced LET expression was significantly correlated with advanced clinical stage, larger tumor size, increased lymph node tumor burden, and poor survival in patient with NPC.…”

Nasopharyngeal carcinoma (NPC) is one of the most common cancers originating in the nasopharynx and occurring at high frequency in South-eastern Asia and North Africa. Long non-coding RNAs (lncRNAs) are a class of non-protein-coding RNA molecules and key regulators of developmental, physiological, and pathological processes in humans. Emerging studies have shown that lncRNAs play critical roles in tumorgenicity and cancer prognosis. With the development of deep sequencing analyses, an extensive amount of functional lncRNAs have been discovered in nasopharyngeal carcinoma tissues and cell lines. However, the roles and mechanisms of aberrantly expressed lncRNAs in the pathogenesis of NPC are not fully understood. In this review, we briefly illustrate the concept, identification, functional characterization, and summarize recent advancements of biological functions of lncRNAs with heterogeneous mechanistic characterization and their involvement in NPC. Then, we describe individual lncRNAs that have been associated with tumorgenesis, growth, invasion, cancer stem cell differentiation, metastasis, drug resistance and discuss the strategies of their therapeutic manipulation in NPC. We also review the emerging insights into the role of lncRNAs and their potential as biomarkers and therapeutic targets for novel treatment paradigms. Finally, we highlight the up-to-date of clinical information involving lncRNAs and future directions in the linking lncRNAs to potential gene therapies, and how modifications of lncRNAs can be exploited for prevention and treatment of NPC.

According to the global cancer statistic, lung cancer is one of the most dangerous tumors, which poses a serious threat to human health. Exploration the mechanism of lung cancer and new targeted therapeutic measures is always the hot topic. Long noncoding RNA (lncRNA) is an important factor affecting the development of tumors. However, the research on the mechanism of lncRNA in the progress of lung cancer needs to be further expanded. In this study, we found that the expression of lncRNA GMDS‐AS1 was significantly reduced in lung adenocarcinoma (LUAD) tissues and cells. Upregulated GMDS‐AS1 can significantly inhibit the proliferation of LUAD cells and promote cell apoptosis in vitro and in vivo. The results indicate that GMDS‐AS1 acts as a tumor suppressor gene to affect the development of LUAD. Further studies revealed that GMDS‐AS1 is a target gene of miR‐96‐5p, and GMDS‐AS1 regulates proliferation and apoptosis of LUAD cells in association with miR‐96‐5p. In addition, we also confirmed that CYLD lysine 63 deubiquitinase (CYLD) is also a target gene of miR‐96‐5p. Through various validations, we confirmed that GMDS‐AS1 can act as a ceRNA to upregulate the expression of CYLD by sponging miR‐96‐5p. Moreover, the intervention of GMDS‐AS1/miR‐96‐5p/CYLD network can regulate the proliferation and apoptosis of LUAD cells. In this study, we revealed that the GMDS‐AS1/miR‐96‐5p/CYLD network based on ceRNA mechanism plays an important role in the development of LUAD and provides a new direction and theoretical basis for targeted therapy of LUAD.
