Long non-coding RNA 657 suppresses hepatocellular carcinoma cell growth by acting as a molecular sponge of miR-106a-5p to regulate PTEN expression

Previous study has identified the aberrant expression of LINC00657, a long non-coding RNA (lncRNA), in human breast cancer. However, the expression pattern, biological function and underlying mechanism of LINC00657 in human hepatocellular carcinoma (HCC) remain obscure. The expression levels of LINC00657 in HCC tissues and cell lines were determined by quantitative real-time PCR. CCK-8 assay, cell colony formation assay, cell cycle analysis, Transwell assay were performed to determine whether LINC00657 could affect HCC progression. Luciferase reporter assay was used to assess the target of LINC00657. Expressions of the relevant proteins were analyzed by Western blot. Herein, we found that LINC00657 was downregulated in HCC tissue specimens as well as in malignant HCC cell lines. LINC00657 overexpression inhibited the proliferation, migration and invasion of HCC cells, while LINC00657 depletion promoted both cell viability and cell invasion in vitro. We also found that LINC00657 could inhibit tumor growth in vivo. Further experiments demonstrated that down-regulated LINC00657 increased the expression of miR-106a-5p. miR-106a-5p decreased the abundances of PTEN protein, while had no impact on PTEN mRNA. Moreover, we identified that both LINC00657 and PTEN mRNA were targets of miR-106a-5p by using dual-luciferase reporter assay. Our results provide the new evidence supporting the tumor-suppressive role of LINC00657 in HCC, suggesting that LINC00657 might play a role in HCC and can be a novel therapeutic target for treating HCC.     

LINC00184 plays an oncogenic role in non-small cell lung cancer via regulation of the miR-524-5p/HMGB2 axis

Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. We aimed to investigate the role of LINC00184 in NSCLC. Migration, proliferation and invasion of NSCLC cells were analysed using the wound healing assay, cell counting kit-8 assay and transwell assay, respectively. Apoptosis and cell cycle were assessed using flow cytometry. Online bioinformatics tools were utilized to predict downstream microRNAs (miRNA) or genes related to LINC00184 expression. The RNA pull-down experiment and luciferase reporter assay were performed to verify the predictions thereof. LINC00184, miR-524-5p, and high mobility group 2 protein (HMGB2) expression levels in NSCLC tissues and cell lines were detected using quantitative real-time polymerase chain reaction. An NSCLC mouse model was constructed for in vivo experiments. LINC00184 overexpression was observed in NSCLC tissues and cell lines and was found to be correlated with poor prognosis. LINC00184 knockdown inhibited cell proliferation, migration and invasion, induced cell cycle arrest and accelerated apoptosis in NSCLC cell lines. LINC00184 suppressed tumour growth and proliferation in NSCLC mouse models and directly targeted the miR-524-5p/HMGB2 axis. Moreover, the expression levels of LINC00184 and HMGB2 were negatively correlated with miR-524-5p expression, whereas LINC00184 expression was positively correlated with HMGB2 expression. LINC00184 affected the cell cycle, proliferation, apoptosis, migration and invasion in NSCLC via regulation of the miR-524-5p/HMGB2 axis.     

LINC01311 exerts an inhibitory effect in thyroid cancer progression by targeting the miR-146b-5p/IMPA2 axis

BackgroundA growing body of research suggests that long non-coding RNA (lncRNA) play an important role during the tumorigenesis and progression of cancers, including thyroid cancer (TC). Herein, we intended to uncover the role and mechanisms of LINC01311 in TC.MethodsThe relative LINC01311, miR-146b-5p, and IMPA2 expressions were quantified by subjecting TC cells and tissues to western blotting and RT-qPCR. CCK-8 and scratch-wound healing assays were carried out for the evaluation of the proliferation and migration of TC cells. The apoptosis was evaluated by flow cytometry assay and western blotting of Bax and Bcl-2 proteins. Xenograft tumor model was also used to study how LINC01311 functions during TC cell growth. Luciferase reporter and RNA immunoprecipitation (RIP) assays were performed to ascertain miR-146b-5p's interactions with LINC01311 and IMPA2 3′UTR.ResultsThe TC cells and tissues exhibited a downregulation of LINC01311 and IMPA2 and an upregulation of miR-146b-5p. LINC01311 overexpression retarded TC cell growth in vitro as well as in vivo. The luciferase reporter and RIP assays verified that miR-146b-5p recognizes LINC01311 and IMPA2 3′UTR by base pairing. LINC01311 overexpression could counteract the oncogenic effect of miR-146b-5p in vitro. Moreover, IMPA2 upregulation could offset the tumor-promoting effect of miR-146b-5p.ConclusionLINC01311-mediated inhibition of TC cell growth was achieved by targeting the miR-146b-5p/IMPA2 axis. These findings support that targeting the LINC01311/miR-146b-5p/IMPA2 axis may be a promising approach against TC progression.     

Long noncoding RNA LINC00629 restrains the progression of gastric cancer by upregulating AQP4 through competitively binding to miR-196b-5p

Gastric cancer continues to be a common cancer in the world with high incidence and mortality. Accumulating evidence has implicated long noncoding RNAs (lncRNAs) in gastric cancer progression. Here, this study identified the potential role of a novel lncRNA, LINC00629 in gastric cancer and to elucidate the underlying mechanism. Initially, microarray-based gene expression profiling of gastric cancer was employed to identify differentially expressed genes. Next, the expression of LINC00629, microRNA-196b-5p (miR-196b-5p) and aquaporin 4 (AQP4) in clinical gastric cancer tissues was determined and the cell line presenting with the lowest LINC00629 expression was selected. The interaction among LINC00629, miR-196b-5p, and AQP4 was identified. Expression of LINC00629, miR-196b-5p, and AQP4 in gastric cancer cells were altered and then biological behaviors of gastric cancer cells were assessed by 5-ethynyl-2′-deoxyuridine and Transwell assays. Tumor formation in vivo was evaluated in nude mice. In gastric cancer, expression of LINC00629 and AQP4 was downregulated, and expression of miR-196b-5p was upregulated. Proliferation, invasion, and migration of gastric cancer cells were reduced after overexpression of LINC00629. LINC00629 competitively bound to miR-196b-5p, while AQP4 was a target of miR-196b-5p. Either downregulating miR-196b-5p or upregulating AQP4 could restrain the development of gastric cancer in vitro. LINC00629 overexpression repressed the growth of transplanted tumors in vivo. Taken together, LINC00629 competitively bound to miR-196b-5p to upregulate AQP4 expression, thereby inhibiting gastric cancer progression. Therefore, understanding of this mechanism may help to improve gastric cancer treatment.     

Long non-coding RNA LINC00488 facilitates thyroid cancer cell progression through miR-376a-3p/PON2

Objective: Long non-coding RNAs (lncRNAs) recently have been identified as influential indicators in a variety of malignancies. The aim of the present study was to identify a functional lncRNA LINC00488 and its effects on thyroid cancer in the view of cell proliferation and apoptosis.Methods: In order to evaluate the effects of LINC00488 on the cellular process of thyroid cancer, we performed a series of in vitro experiments, including cell counting kit-8 (CCK-8) assay, EdU (5-ethynyl-2′-deoxyuridine) assay, flow cytometry, transwell chamber assay, Western blot and RT-qPCR. The target gene of LINC00488 was then identified by bioinformatics analysis (DIANA and TargetScan). Finally, a series of rescue experiments was conducted to validate the effect of LINC00488 and its target genes on proliferation, migration, invasion and apoptosis of thyroid cancer.Results: Our findings revealed that LINC00488 was highly expressed in thyroid cancer cell lines (BCPAP, BHP5-16, TPC-1 and CGTH-W3) and promoted the proliferation, migration and invasion, while inhibited the apoptosis of thyroid cancer cells (BCPAP and TPC-1). The results of bioinformatics analysis and dual luciferase reporter gene assay showed that LINC00488 could directly bind to miR-376a-3p and down-regulated the expression level of miR-376a-3p. In addition, Paraoxonase-2 (PON2) was a target gene of miR-376a-3p and negatively regulated by miR-376a-3p. Rescue experiment indicated that LINC00488 might enhance PON2 expression by sponging miR-376a-3p in thyroid cancer.Conclusion: Taken together, our study revealed that lncRNA LINC00488 acted as an oncogenic gene in the progression of thyroid cancer via regulating miR-376a-3p/PON2 axis, which indicated that LINC00488-miR-376a-3p-PON2 axis could serve as novel biomarkers or potential targets for the treatment of thyroid cancer.     

LINC01783 accelerated tongue squamous cell carcinoma progression via inhibiting miR-199b-5p

Growing studies illustrated that lncRNAs exert critical roles in development and occurrence of tumours including TSCC. In this research, we indicated that LINC01783 was up-regulated in TSCC cells (SCC1, Cal27, UM1 and SCC4) when compared to NHOK cell. RT-qPCR analysis indicated that LINC01783 was overexpressed in 22 TSCC cases (73.3%, 22/30) compared with no-tumour specimens. LINC01783 level was up-regulated in TSCC specimens when compared to no-tumour specimens. Ectopic expression of LINC01783 promoted TSCC cell cycle and growth and EMT progression in both TSCC cell SCC1 and Cal27. Overexpression of LINC01783 sponged miR-199b-5p in TSCC cell and elevated expression of LINC01783 inhibited miR-199b-5p expression. Moreover, we illustrated that miR-199b-5p was down-regulated in TSCC cells and specimen and LINC01783 level was up-regulated in TSCC specimens when compared to no-tumour specimens. Elevated expression of LINC01783 promoted TSCC cell growth, cycle and EMT progression by sponging miR-199b-5p. These data suggested that LINC01783 functioned as one oncogene and might be one treatment target for TSCC.

Silencing LINC00504 inhibits cell proliferation,invasion as well as migration and promotes cell apoptosis in lung cancer cells via upregulating miR-876-3p

LINC00504 acts as an oncogene and associates with unfavorable prognosis in patients with lung cancer. Silencing LINC00504 may be a promising strategy for treatment of lung cancer and its effects were firstly investigated in lung cancer cells this study. The gene expression level of miR-876-3p as well as LINC00504 were measured via PCR assay. The cell proliferation was investigated through Cell Counting Kit-8 (CCK-8) assay and colony formation assay. Flow cytometry was applied for detection of cell apoptosis. Wound healing and transwell assay were performed for measurement of cell migration and invasion respectively. The apoptosis related protein expressions were measured by western blot. Luciferase report assay was conducted for verification the target gene. LINC00504 was higher expressed in five types of lung cancer cells studied herein when compared with the control normal cells. LINC00504 knockdown exerted inhibitory effects on cell apoptosis, cell migration as well as cell invasion and promoted cell apoptosis. All the effects mentioned above were counteracted by miR-876-3p inhibitor. Silencing LINC00504 possessed anti-proliferation, repression of cell invasion as well as migration and pro-apoptosis effects via targeting up-regulation of miR-876-3p in lung cancer cells, proving the new therapeutic targets and highlighting the potential application in future diagnosis and treatment in lung cancer.     

miR-605-5p promotes invasion and proliferation by targeting TNFAIP3 in non–small-cell lung cancer

Lung cancer is an significant cause of death worldwide, and non–small-cell lung cancer (NSCLC) is the most common type of lung cancer. MicroRNAs (miRNAs) have been identified to play key roles in NSCLC development. Recently, it has been reported that miR-605-5p is a cancer-related miRNA in several types of tumors. In this study, we study the role of miR-605-5p in NSCLC cells. We find that miR-605-5p is upregulated in NSCLC cells. Overexpression of miR-605-5p significantly promotes lung cancer invasion and migration in H460 and H1299 cells. Besides this, miR-605-5p also promotes lung cancer cell carcinoma proliferation and metastasis in vivo. However, downregulation of miR-605-5p inhibits cell invasion and migration by inhibiting lung cancer cell carcinoma proliferation and metastasis. In addition, the luciferase report assay identifies 3′-untranslated region tumor necrosis factor α-induced protein 3 (TNFAIP3) as a target of miR-605-5p. Silencing of TNFAIP3 promotes invasion and proliferation in lung cancer. In addition, the knockdown of TNFAIP3 restores the significant decrease in invasion and proliferation in miR-605-5p-inhibitor–transfected lung cancer cells. In conclusion, miR-605-5p promotes invasion and proliferation by targeting TNFAIP3 in NSCLC, and may provide possible biomarkers for NSCLC therapy.     

Huaier suppresses proliferation and induces apoptosis in human pulmonary cancer cells via upregulation of miR-26b-5p

Various studies have reported that Huaier possesses anti-tumor effects. However, the mechanisms are not completely elucidated. Here, we found 66 differentially expressed miRNAs in Huaier-treated pulmonary adenocarcinoma A549 cells, with upregulation of miR-26b-5p. Transfection of A549 cells with miR-26b-5p mimic inhibited proliferation and induced apoptosis, while transfection of Huaier-treated A549 cells with a miR-26b-5p inhibitor reversed the effects of Huaier. EZH2 was verified as the target of miR-26b-5p. Thus, our findings indicate that Huaier might suppress proliferation and induce apoptosis in lung cancer cells via a miR-26b-5p-EZH2-mediated approach, which provides a new perspective for understanding the anti-tumor effects of Huaier.

Effects of long non-coding RNA LINC00667 on renal tubular epithelial cell proliferation,apoptosis and renal fibrosis via the miR-19b-3p/LINC00667/CTGF signaling pathway in chronic renal failure

The global prevalence of chronic renal failure (CRF) has significantly elevated with various reports indicating there to be a 10% worldwide rate. The functions of long non-coding RNAs (lncRNAs) and their deeper association with CRF at present remain poorly understood. Hence, the aim of the present study was to investigate the altered expressions of lncRNA LINC00667 in CRF and its associated effects on renal tubular epithelial cell proliferation, apoptosis and renal fibrosis through the microRNA-19b-3p (miR-19b-3p)/LINC00667/connective tissue growth factor (CTGF) signaling pathway. Initially, verification of the targeting relationship between LINC00667, CTGF and miR-19b-3p was performed, after which evidence was obtained indicating that miR-19b-3p could negatively regulate LINC00667 and CTGF. The expressions of CTGF in both the CRF and normal renal tissues were determined by immunohistochemistry means, with LINC00667 and CTGF determined to be highly expressed, while poor expression levels of miR-19b-3p were detected among the CRF tissues. The expressions of LINC00667, miR-19b-3p, fibrosis- and epithelial-mesenchymal transition (EMT)-related genes were also examined. The successfully established CRF rat models were treated with varying mimics, inhibitors, and siRNA. ELISA was applied to determine the renal function-related factors. Besides, the renal cell proliferation, migration and apoptosis were detected. In response to LINC00667 silencing, the renal tubular epithelial cells displayed increased proliferation and migration accompanied by reduced apoptosis based on upregulated miR-19b-3p, along with inhibited renal fibrosis and EMT detected. Taken together, the key findings of our study demonstrated that decreased lncRNA LINC00667 could promote renal tubular epithelial cell proliferation and ameliorate renal fibrosis in CRF via the miR-19b-3p/LINC00667/CTGF signaling pathway.

Long intergenic noncoding RNA 00641 inhibits breast cancer cell proliferation,migration, and invasion by sponging miR-194-5p

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.     

LINC01140 regulates osteosarcoma proliferation and invasion by targeting the miR-139-5p/HOXA9 axis

Osteosarcoma is one of the commonest metastatic tumor in children and teenagers, and has a hopeless, prognosis. Long non-coding RNA (lncRNA) acts momentous roles as a regulator on the proliferation and migration of cancer. Here, we performed GEO database analysis and qPCR to identify differentially expressed lncRNAs in osteosarcoma cells. Knockdown of lncRNA LINC01140 was used to detect the effect of LINC01140 on the proliferation, invasion, and epithelial-mesenchymal transition (EMT) of osteosarcoma cells. Bioinformatics analysis and qPCR identified the LINC01140/miR-139-5p/Homeobox A9 (HOXA9) regulatory axis. RNA immunoprecipitation assay, Dual-luciferase assay, and rescue experiments confirmed the interaction of LINC01140/miR-139-5p/HOXA9 in osteosarcoma. LINC01140 was overexpressed in osteosarcoma and knocking down LINC01140 restrained the proliferation and invasion of osteosarcoma cells and EMT. In Saos2 and MG63 cells, LINC01140 sponged miR-139-5p, and a miR-139-5p inhibitor overturned the suppression of LINC01140 knockdown on the proliferation and migration of osteosarcoma cells. Moreover, miR-139-5p depressed the invasion, proliferation, and EMT of osteosarcoma cells via targeting HOXA9. Our results indicate that LINC01140 downregulation inhibits the invasion, proliferation, and EMT in osteosarcoma cells through targeting the miR-139-5p/HOXA9 axis. Therefore, LINC01140 is a potential therapeutic target for osteosarcoma.     

LINC00657 expedites neuropathic pain development by modulating miR-136/ZEB1 axis in a rat model

Long non-coding RNAs (lncRNAs) are involved in the progression of several diseases. The interactions among lncRNAs, microRNA (miRNAs) or their targeting genes are reported to play crucial roles in the development of diseases. LINC00657 is observed to be upregulated in several cancers. However, the biological role of LINC00657 in neuropathic pain progress is unclear. Hence, in our study, we aimed to investigate the function of LINC00657 in neuropathic pain development. A chronic constriction injury (CCI) rat model was established, and we found that LINC00657 was greatly increased in CCI rats associated with a decrease of miR-136. Inhibition of LINC00657 suppressed neuropathic pain via alleviating mechanical and thermal hyperalgesia. In addition, miR-136 overexpression can also inhibit the neuropathic pain development. MiR-136 was predicted to serve as a miRNA target of LINC00657, and dual-luciferase reporter assay confirmed the correlation between LINC00657 and miR-136. Moreover, we observed that the decrease of LINC00657 was able to inhibit the neuroinflammation of CCI rats by targeting expression of cyclooxygenase-2, tumor necrosis factor-α and interleukin-1β while miR-136 inhibitors reversed this phenomenon. Next, by using bioinformatics analysis, ZEB1 was predicted as a direct target of miR-136, and miR-136 could negatively modulate ZEB1 expression. Besides these, ZEB1 was remarkably increased in the CCI rats. Knockdown of ZEB1 can inhibit neuropathic pain development, while miR-136 inhibitors can reverse it. In conclusion, it was implied that LINC00657 can induce the neuropathic pain development via regulating miR-136/ZEB1 axis.
