“…lncRNAs are involved in numerous physiological processes, including cell growth, proliferation, apoptosis, migration and differentiation (17)(18)(19). The normal expression of lncRNA is necessary to maintain cell homeostasis and function, and its aberrant expression is closely associated with a variety of diseases, including cancer (20,21).…”

Laryngeal carcinoma is the most common type of malignant tumor in the head and neck. Long non-coding RNAs (lncRNAs) serve crucial roles in numerous biological processes. The present study aimed to investigate the role of lncRNA SOX2-OT in laryngeal cancer and to reveal the underlying mechanisms. Reverse transcription-quantitative PCR assays were used to measure the expression levels of SOX2-OT in the laryngeal cell lines. Furthermore, cell proliferation, apoptosis, migration and invasion were assessed by CCK-8, flow cytometry, wound healing and Transwell assays, respectively. Western blot assay was performed to detect the protein expressions. In addition, a dual-luciferase reporter assay was performed to confirm the direct interaction between SOX2-OT and microRNA (miR)-654. The data demonstrated that SOX2-OT level were significantly increased in the laryngeal cell lines. Furthermore, SOX2-OT silencing markedly promoted apoptosis and suppressed the proliferation, migration and invasion of TU-177 cells. A dual-luciferase reporter assay revealed that miR-654 was a direct target of SOX2-OT. Moreover, downregulation of miR-654 could attenuate cell apoptosis and accelerate cell proliferation, migration and invasion in TU-177 cells. In summary, the present study reported that knockdown of SOX2-OT could suppress cell proliferation, migration and invasion, and induce apoptosis in laryngeal cancer by targeting miR-654.

“…Initially, lncRNAs are thought to be RNAs that have no biologically function. However, subsequent studies have shown that lncRNAs play important roles in transcriptional, post‐transcriptional, and epigenetic processes . LncRNA has a structure similar to mRNA and has a promoter structure and a polyA tail .…”

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.

“…Rs3787016, localizes to the fourth intron of RNA polymerase II polypeptide E (POLR2E) 16 gene, has been investigated by several researchers on its association with cancer risk [16,[30][31][32][33][34][35][36][37].The most important function of LncRNAs is involvement in the transcriptional or posttranscriptional regulation of gene expression [38]. Abnormal expressions of these RNAs facilitate tumor-cell proliferation, invasion and survival in cancer development and progression [39][40][41].…”

Background It has been proved that a significant proportion of prostate cancer diagnoses may be associated with a strong hereditary component. Micro-RNAs and Long Non-coding RNAs are a group of a noncoding small molecule, which play critical roles in signalling pathways, metabolism, apoptosis and cancer development. Exercising a meta-analysis to examine the relationship between rs3746444, rs3787016 and prostate cancer (PCa) risk was the main objective of our study. Results 10 case-control studies were included, while 6 on rs3787016 and 4 on rs3746444. On the whole, the genotypes carrying the T allele, in which were verified an increased risk between rs3787016 and PCa risk.( T vs C: odds ratio(OR) = 1.802, 95% CI 1.015–3.198, P value of heterogeneity(PH) = 0.00%; CT vs CC: OR = 1.179,95% CI 1.091–1.275, PH = 0.41; TT vs CC: .OR = 1.418, 95% CI 1.229–1.636, PH= 0.961; TT + CT vs CC: OR = 1.216, 95% CI 1.129–1.310, PH= 0.408; TT vs CT + CC: OR = 1.328, 95%CI 1.159–1.521, PH = 0.987). A vital relevance was performed by this meta-analysis in three models between rs3746444 and PCa risk, in which a tendency of increased PCa risk could be found (C vs T: OR = 1.197, 95% CI 1.035–1.384, PH= 0.837; CC vs TT: OR = 1. 137, 95% CI 0.813–1.590, PH = 0.392; CC + CT vs TT: OR = 1.426, 95% CI 1.166–1.743, PH= 0.406.). Conclusion Our findings proposed that rs3746444 in MiRNA-499 and rs3787016 in Long Non-coding RNAs POLR2E polymorphisms increased the risk of developing PCa. Further functional studies are warranted to reveal the role of the polymorphism in carcinogenesis.
