Wang Y, Ren H. Multi-omics sequencing revealed endostar combined with cisplatin treated non small cell lung cancer via anti-angiogenesis. BMC Cancer 2024; 24:187. [PMID: 38331776 PMCID: PMC10854066 DOI: 10.1186/s12885-023-11665-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Accepted: 11/21/2023] [Indexed: 02/10/2024] Open
Abstract
BACKGROUND Endostar, an anti-angiogenic drug, has been approved for treating non-small cell lung cancer (NSCLC). At present, endostar combined with radiotherapy or chemotherapy has achieved ideal results in the treatment of some tumors, but there is a lack of application and study in NSCLC. This study investigated the therapeutic effect and potential mechanism of endostar combined with cisplatin (EC) in NSCLC. METHODS HE staining, TUNEL staining, immunofluorescence, colony formation ability, and cell migration ability were used to evaluate the anti-tumor activity of EC. The expressions of FMOD, VEGF, FGF-2, and PDGF-B were detected by western blotting and qPCR. The target of combination therapy was analyzed by m6A sequencing and RNA sequencing. METTL3 knockdown and overexpressed A549 cells were constructed and co-cultured with HUVECs to further evaluate the effect of METLL3 on combination therapy. RESULTS Combination therapy significantly reduced the colony formation and migration ability of NSCLC cells, induced cell apoptosis, and inhibited the tube formation ability of HUVECs. The results of m6A sequencing and RNA sequencing showed that the EC could down-regulate the expression level of FMOD in tumor tissues, which might be related to the reduction of its m6A methylation modification regulatory enzyme METTL3. Restricting FMOD expression could reduce the expression of FGF2, TGF-β1, VEGF and PDGF-B. Moreover, overexpression of METTLE almost abolished the anti-tumor effect of EC and promoted angiogenesis. CONCLUSIONS Endostar combined with cisplatin might exert anti-tumor effects by down-regulating the expression of METTL3 and FMOD.

Discovering potential inhibitors of Raf proto-oncogene serine/threonine kinase 1: a virtual screening approach towards anticancer drug development. J Biomol Struct Dyn 2024; 42:1846-1857. [PMID: 37104027 DOI: 10.1080/07391102.2023.2204380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Accepted: 04/08/2023] [Indexed: 04/28/2023]
Abstract
Raf proto-oncogene serine/threonine kinase 1 (RAF1 or c-Raf) is a serine/threonine protein kinase crucial in regulating cell growth, differentiation, and survival. Any disruption or overexpression of RAF1 can result in neoplastic transformation and other disorders such as cardiomyopathy, Noonan syndrome, leopard syndrome, etc. RAF1 has been identified as a potential therapeutic target in drug development against various complex diseases, including cancer, due to its remarkable role in disease progression. Here, we carried out a multitier virtual screening study involving different in-silico approaches to discover potential inhibitors of RAF1. After applying the Lipinski rule of five, we retrieved all phytocompounds from the IMPPAT database based on their physicochemical properties. We performed a molecular docking-based virtual screening and got top hits with the best binding affinity and ligand efficiency. Then we screened out the selected hits using the PAINS filter, ADMET properties, and other druglike features. Eventually, PASS evaluation identifies two phytocompounds, Moracin C and Tectochrysin, with appreciable anti-cancerous properties. Finally, all-atom molecular dynamics simulation (MDS) followed by interaction analysis was performed on the elucidated compounds in complex with RAF1 for 200 ns to investigate their time-evolution dynamics and interaction mechanism. Molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) and Dynamical Cross-Correlation Matrix (DCCM) analyses then followed these results from the simulated trajectories. According to the results, the elucidated compounds stabilize the RAF1 structure and lead to fewer conformational alterations. The results of the current study indicated that Moracin C and Tectochrysin could serve as potential inhibitors of RAF1 after required validation.Communicated by Ramaswamy H. Sarma.

Abstract
(1) Background: Mounting evidence supports the idea that one of the most critical agents in controlling gene expression could be long non-coding RNAs (lncRNAs). Upregulation of lncRNA is observed in the different processes related to pathologies, such as tumor occurrence and development. Among the crescent number of lncRNAs discovered, FLVCR1-AS1 and FBXL19-AS1 have been identified as oncogenes in many cancer progression and prognosis types, including cholangiocarcinoma, gastric cancer, glioma and glioblastoma, hepatocellular carcinoma, lung cancer, ovarian cancer, breast cancer, colorectal cancer, and osteosarcoma. Therefore, abnormal FBXL19-AS1 and FLVCR1-AS1 expression affect a variety of cellular activities, including metastasis, aggressiveness, and proliferation; (2) Methods: This study was searched via PubMed and Google Scholar databases until May 2022; (3) Results: FLVCR1-AS1 and FBXL19-AS1 participate in tumorigenesis and have an active role in impacting several signaling pathways that regulate cell proliferation, migration, invasion, metastasis, and EMT; (4) Conclusions: Our review focuses on the possible molecular mechanisms in a variety of cancers regulated by FLVCR1-AS1 and FBXL19-AS1. It is not surprising that there has been significant interest in the possibility that these lncRNAs might be used as biomarkers for diagnosis or as a target to improve a broader range of cancers in the future.

Abstract
PURPOSE This study aimed to explore the role and underlying mechanism of circular RNA (circRNA) reticulon 1 (circRTN1) in thyroid cancer (TC). METHODS The expression levels of circRTN1, microRNA-431-5p (miR-431-5p), and transforming growth factor-alpha (TGFA) mRNA were measured by quantitative real-time PCR (qRT-PCR). Cell proliferation was evaluated using colony formation and 5-ethynyl-2'-deoxyuridine (EdU) assays. Cell apoptosis was analyzed using flow cytometry. Cell migration and invasion were measured using the transwell assay. The protein levels of ki-67, Bax, matrix metalloproteinase 2 (MMP-2), and TGFA were detected using Western blot assay. The interaction between miR-431-5p and circRTN1 or TGFA was verified by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. The effect of circRTN1on TC in vivo was explored via xenograft tumor assay. RESULTS The expression of circRTN1 was increased in TC tissues and cells. Knockdown of circRTN1 suppressed TC cell proliferation, migration, and invasion, and increased cell apoptosis. MiR-431-5p was a target of circRTN1, and miR-431-5p downregulation reversed the role of circRTN1 knockdown in TC cells. TGFA was identified as a direct target of miR-431-5p, and miR-431-5p exerted the anti-tumor role in TC cells by downregulating TGFA. Moreover, circRTN1 sponged miR-431-5p to regulate TGFA expression. Furthermore, circRTN1 knockdown inhibited tumor growth in vivo. CONCLUSION CircRTN1 acted as a cancer-promoting circRNA in TC by regulating the miR-431-5p/TGFA axis, providing a potential therapeutic strategy for TC treatment.

Abstract
Lung cancer is the second cancer and the leading cause of tumor-related mortality worldwide. Angiogenesis is a crucial hallmark of cancer development and a promising target in lung cancer. However, the anti-angiogenic drugs currently used in the clinic do not achieve long-term efficacy and are accompanied by severe adverse reactions. Therefore, the development of novel anti-angiogenic therapeutic approaches for lung cancer is urgently needed. Non-coding RNAs (ncRNAs) participate in multiple biological processes in cancers, including tumor angiogenesis. Many studies have demonstrated that ncRNAs play crucial roles in tumor angiogenesis. This review discusses the regulatory functions of different ncRNAs in lung cancer angiogenesis, focusing on the downstream targets and signaling pathways regulated by these ncRNAs. Additionally, given the recent trend towards utilizing ncRNAs as cancer therapeutics, we also discuss the tremendous potential applications of ncRNAs as biomarkers or novel anti-angiogenic tools in lung cancer.

Abstract
We aim to discuss the role of miR-431-5p in colorectal cancer (CRC) progression via regulating peroxiredoxin 1 (PRDX1). miR-431-5p and PRDX1 expression were detected in CRC tissues and cells, and the relationship between miR-431-5p expression and prognosis of CRC patients was analyzed. Exosomes were extracted from human umbilical cord mesenchymal stem cells (hUCMSCs) and co-cultured with LoVo cells. MTT assay, flow cytometry and Transwell assay were implemented to test cell viability, apoptosis and invasion and migration ability, respectively. The tumor growth was determined as well, and the binding relation between miR-431-5p and PRDX1 was confirmed. miR-431-5p was downregulated and PRDX1 was upregulated in CRC, and miR-431-5p downregulation was associated with poor prognosis. hUCMSC-Exos suppressed the malignant behaviors of LoVo cells, and overexpression of miR-431-5p further aggravated the inhibitory effect of hUCMSC-Exos on LoVo cells. hUCMSC-Exos inhibited PRDX1 expression via miR-431-5p. PRDX1 was targeted by miR-431-5p. miR-431-5p serves as a prognostic biomarker in CRC, and hUCMSC-Exos transfer of miR-431-5p decelerates CRC cell growth by inhibiting PRDX1.

Abstract
Radiation resistance largely limits the survival of patients with non-small-cell lung cancer (NSCLC). To understand the mechanism underlying radiation resistance, we explored the influence of LINC01578 in radiation-resistant NSCLC cells. LINC01578, miR-216b-5p and Transducin (beta)-like 1 X-linked receptor 1 (TBL1XR1) expression was evaluated in patients with NSCLC, and their correlation with patients' prognosis was examined. Radiation-resistant NSCLC cell line (A549-RR) was induced and treated with oligonucleotide or plasmid transfection, and cell biological functions were captured. The interplay between LINC01578, miR-216b-5p and TBL1XR1 was clarified. NSCLC patients showed high LINC01578 and TBL1XR1 expression, and low miR-216b-5p expression, which was correlated to shorter patients' prognosis, respectively. LINC01578 or TBL1XR1 deficiency or miR-216b-5p elevation suppressed the functional activities of A549-RR cells. LINC01578 suppression elevated miR-216b-5p expression, consequently leading to the down-regulation of TBL1XR1. miR-216b-5p silencing or TBL1XR1 overexpression compromised LINC01578 knockdown's effects on radiation resistance of A549-RR cells. In brief, LINC01578 suppresses miR-216b-5p and enhances TBL1XR1 expression, thus to promote biological functions of radiation-resistant NSCLC cells.

Abstract
Studies have revealed the relationship between histone deacetylases (HDACs)/microRNAs (miRNAs) and sepsis, but little has ever investigated the mechanism of HDAC1/miR-124-5p in sepsis. Herein, we studied the impacts of HDAC1/miR-124-5p on myocardial damage of septic mice via regulating high-mobility group box chromosomal protein 1 (HMGB1). Septic mice were induced by cecal ligation and puncture. HDAC1, miR-124-5p and HMGB1 expression in myocardial tissues of septic mice were detected. Septic mice were injected with HDAC1 low expression-, miR-124-5p high expression- or HMGB1 low expression-related structures to observe cardiac function, inflammatory response, oxidative stress response, myocardial pathological changes and apoptosis in myocardial tissues of septic mice. The relationship of HDAC1/miR-124-5p/HMGB1 was verified. HDAC1 and HMGB1 expression were upregulated while miR-124-5p expression was decreased in myocardial tissues of septic mice. Restored miR-124-5p/depleted HDAC1 or HMGB1 recovered the cardiac function, improved cardiac function, inflammatory response, oxidative stress response, myocardial pathological changes and inhibit ed cardiomyocyte apoptosis in septic mice. HDAC1 bound to miR-124-5p which directly targeted HMGB1. This study suggests that down-regulated HDAC1 or up-regulated miR-124-5p recovers myocardial damage of septic mice via decreasing HMGB1.

Abstract
BACKGROUND Several immune-associated long non-coding RNA (lncRNA) signatures have been reported as prognostic models in different types of cancers; however, the immune-associated lncRNA signature for predicting overall survival (OS) in cervical cancer is unknown. METHODS The lncRNA expression profiles and clinical data of cervical cancer were acquired from The Cancer Genome Atlas (TCGA) dataset. Immune-associated genes were extracted from the Molecular Signatures Database (MSigDB), and the immune-associated lncRNAs were extracted for Cox regression analysis. Principal component analysis (PCA) was used to distinguish the high and low risk status of cervical cancer patients. Gene Set Enrichment Analysis (GSEA) was used for functional analyses. RESULTS Cox regression analyses and the least absolute shrinkage and selection operator (LASSO) Cox regression model were used to construct an immune-associated ten-lncRNA signature (containing AL021807.1, AL109976.1, LINC02446, MIR4458HG, AC004540.2, AC009065.8, AC083809.1, AC055822.1, AP000904.1, and FBXL19-AS1) for predicting OS in cervical cancer. The signature segregated the cervical cancer patients into 2 groups (high-risk group and low-risk group). The Kaplan-Meier survival curves of AL021807.1, AL109976.1, LINC02446, and MIR4458HG were statistically significant (P<0.05) and the others (including AC004540.2, AC009065.8, AC083809.1, AC055822.1, AP000904.1, and FBXL19-AS1) were not statistically significant (P>0.05). The Kaplan-Meier survival curves of the signature were statistically significant (P=1.134e-10), and the 5-year survival rate was 0.444 in the high-risk group [95% confidence interval (CI): 0.334 to 0.590] and 0.884 in the low-risk group (95% CI: 0.807 to 0.969). The area under curve (AUC) of the receiver operating characteristic (ROC) curve of the signature was 0.833. The concordance index (C-index) of the signature was 0.788 (95% CI: 0.730 to 0.846, P=1.884778e-22). The PCA successfully distinguished the high-risk group and low-risk group based on the signature. The GSEA showed that the signature-related protein coding genes (PCGs) may participate in immunologic biological processes and pathways. CONCLUSIONS This study revealed that the immune-associated ten-lncRNA signature is an independent factor for cervical cancer prognosis prediction, providing a bright future for immunotherapy of cervical cancer patients.

Master Regulators of Epithelial-Mesenchymal Transition and WNT Signaling Pathways in Juvenile Nasopharyngeal Angiofibromas. Biomedicines 2021; 9:biomedicines9091258. [PMID: 34572445 PMCID: PMC8469518 DOI: 10.3390/biomedicines9091258] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 08/31/2021] [Accepted: 09/06/2021] [Indexed: 02/08/2023] Open
Abstract
Juvenile nasopharyngeal angiofibroma (JNA) is a rare fibrovascular benign tumor showing an invasive growth pattern and affecting mainly male adolescents. We investigated the role of epithelial–mesenchymal transition (EMT) and WNT signaling pathways in JNA. Gene expression profiles using nine JNA paired with four inferior nasal turbinate samples were interrogated using a customized 2.3K microarray platform containing genes mainly involved in EMT and WNT/PI3K pathways. The expression of selected genes (BCL2, CAV1, CD74, COL4A2, FZD7, ING1, LAMB1, and RAC2) and proteins (BCL2, CAV1, CD74, FZD7, RAF1, WNT5A, and WNT5B) was investigated by RT-qPCR (28 cases) and immunohistochemistry (40 cases), respectively. Among 104 differentially expressed genes, we found a significantly increased expression of COL4A2 and LAMB1 and a decreased expression of BCL2 and RAC2 by RT-qPCR. The immunohistochemistry analysis revealed a low expression of BCL2 and a negative to moderate expression of FZD7 in most samples, while increased CAV1 and RAF1 expression were detected. Moderate to strong CD74 protein expression was observed in endothelial and inflammatory cells. A significant number of JNAs (78%) presented reduced WNT5A and increased WNT5B expression. Overall, the transcript and protein profile indicated the involvement of EMT and WNT pathways in JNA. These candidates are promising druggable targets for treating JNA.

Circulating Hsa-miR-431-5p as Potential Biomarker for Squamous Cell Vulvar Carcinoma and Its Premalignant Lesions. Diagnostics (Basel) 2021; 11:diagnostics11091706. [PMID: 34574047 PMCID: PMC8465739 DOI: 10.3390/diagnostics11091706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 09/07/2021] [Accepted: 09/15/2021] [Indexed: 11/20/2022] Open
Abstract
Vulvar squamous cell carcinoma (VSCC) develops from high-grade squamous intraepithelial lesions (HSIL) and differentiated vulvar intraepithelial neoplasia (dVIN). This study aimed to assess the diagnostic value of circulating hsa-miR-431-5p in vulvar precancers and VSCC. Expression levels of hsa-miR-431-5p were analyzed by quantitative RT-PCR in plasma samples of 29 patients with vulvar precancers (HSIL or dVIN), 107 with VSCC as well as 15 healthy blood donors. We used hsa-miR-93-5p and hsa-miR-425-5p as normalizers. The levels of miR-431-5p were increased in the blood of patients with VSCC compared to those with vulvar precancers. Statistically significant differences in the survival rates (time to progression) were revealed for VSCC patients categorized by miR-431-5p levels. Low levels of circulating miR-431-5p were found to be indicative of unfavorable survival rates. In summary, our data reveal the diagnostic potential of circulating miR-431-5p in patients with vulvar precancers and VSCC.

[PMID: 34399848 PMCID: PMC8365943 DOI: 10.1186/s40709-021-00151-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Accepted: 07/27/2021] [Indexed: 12/09/2022]
Abstract
BACKGROUND Cervical cancer (CC) is one of the most common and malignant tumors in women. In this study, we aim to explore the role and mechanism of F-box and leucine rich repeat protein 19 antisense RNA 1 (FBXL19-AS1), a novel long-chain non coding RNA (lncRNA) with marked roles in a variety of tumors, in regulating the proliferation and metastasis of CC. METHODS The expression of FBXL19-AS1, miR-193a-5p and COL1A1 were detected by RT-PCR and western blot. Gain- and loss-of functional assays of FBXL19-AS1 and miR-193a-5p were performed in CC cell lines in vitro or in vivo. The proliferation, migration, invasion, apoptosis and epithelial-mesenchymal transition (EMT) of CC cells were determined. RESULTS FBXL19-AS1 and COL1A1 were significantly up-regulated in CC tissues, while miR-193a-5p was significantly down-regulated. Overexpression of FBXL19-AS1 significantly promoted the proliferation, migration, invasion, EMT and growth of CC cells and inhibited apoptosis, while knockdown of FBXL19-AS1 had the opposite effects. On the other hand, miR-193a-5p inhibited the proliferation and metastasis of CC cells. Mechanistically, FBXL19-AS1 functioned as a competitive endogenous RNA (ceRNA) and inhibited the expression of miR-193a-5p, which targeted at the 3'-UTR site of COL1A1 and negatively regulated COL1A1 expression. CONCLUSIONS FBXL19-AS1 promotes the proliferation and metastasis of CC cells by sponging miR-193a-5p and up-regulating COL1A1.

Abstract
To identify circular RNAs (circRNAs) with tumor suppressor activity against cervical adenocarcinoma, we compared the circRNA levels of cervical adenocarcinoma and normal cervical tissues. We found that circSPIDR was dramatically downregulated in cervical adenocarcinoma tissues. In cervical adenocarcinoma cells, overexpression of circSPIDR reduced cell viability, inhibited colony formation and promoted apoptosis, whereas knockdown of circSPIDR exerted the opposite effects. CircSPIDR overexpression also suppressed the tumorigenicity of cervical adenocarcinoma cells in a xenograft mouse model. CircSPIDR was found to sponge miR-431-5p, thereby de-repressing sortin-related VPS10 domain-containing receptor 1 (SORCS1) and cubilin (CUBN) and inhibiting the development of cervical adenocarcinoma. In clinical cervical samples, circSPIDR expression correlated negatively with miR-431-5p expression and positively with SORCS1 and CUBN expression. These results demonstrated that circSPIDR suppresses cervical adenocarcinoma by competitively binding to miR-431-5p, thus upregulating SORCS1 and CUBN. These findings suggest circSPIDR could serve as a novel therapeutic target for treatment of cervical adenocarcinoma patients.

Abstract
Long non‑coding RNAs (lncRNAs) have been shown to function as crucial regulators in the progression of various types of cancer, including nasopharyngeal carcinoma (NPC). The aim of the present study was to investigate the mechanisms underlying the role of the FBXL19‑AS1/microRNA (miR)‑431/prostate and breast cancer overexpressed 1 (PBOV1) axis in the progression of NPC. The expression levels of FBXL19‑AS1, miR‑431 and PBOV1 were assessed by reverse transcription‑quantitative PCR. The Cell Counting Kit‑8 assay was utilized to detect cell viability. Cell migration and invasion were determined using a Transwell assay. The associations between FBXL19‑AS1 and miR‑431 or miR‑431 and PBOV1 were verified via bioinformatics analysis, dual‑luciferase and RNA‑binding protein immunoprecipitation assays. It was demonstrated that the expression levels of FBXL19‑AS1 and PBOV1 were upregulated in NPC tissues and cells, whereas miR‑431 expression was downregulated. FBXL19‑AS1 directly interacted with miR‑431. FBXL19‑AS1 silencing inhibited the viability, migration and invasion of C666‑1 and SUNE1 cells, whereas these effects could be alleviated by suppressing miR‑431. miR‑431 could target the 3'‑untranslated region of PBOV1. Overexpression of PBOV1 neutralized the miR‑431‑mediated suppression of NPC progression. Moreover, FBXL19‑AS1 could regulate PBOV1 by sponging miR‑431 in NPC cells. In conclusion, the lncRNA FBXL19‑AS1 accelerated NPC progression via the miR‑431/PBOV1 axis, suggesting that it may serve as a potential therapeutic target for patients with NPC.

Abstract
Lung cancer is the leading cause of cancer-related deaths worldwide, in which angiogenesis is highly required for lung cancer cell growth and metastasis. Genetic regulation of this multistep process is being studied extensively, however, relatively less is known about the epigenetic regulation of angiogenesis in lung cancer. Several epigenetic alterations contribute to regulating angiogenesis, such as epimodifications of DNA, posttranslational modification of histones, and expression of noncoding RNAs. Here, we review the current knowledge of the epigenetic regulation of angiogenesis and discuss the potential clinical applications of epigenetic-based anticancer therapy in lung cancer. Overall, epigenetic-based therapy will likely emerge as a prominent approach to treat lung cancer in the future.

Abstract
BACKGROUND Lung squamous cell carcinoma (LUSC) is a kind of lung cancer which possesses high morbidity and mortality. Long non-coding RNAs (lncRNAs) have been abundantly reported to participate in regulating cellular activities of various diseases, including cancers. LINC01116 was reported as a tumor promoter in some cancers, whereas its function has not been clarified in LUSC. OBJECTIVE This exploration aimed to study the modulatory role of LINC01116 in LUSC. METHODS The expressions of LINC01116, miR-744-5p and SCN1B were determined by RT-qPCR. CCK-8, EdU and transwell assays were conducted to evaluate the proliferative, migratory and invasive abilities of A549 and H1299 cells. The protein expression of SCN1B or EMT-associated proteins was examined through western blot assay. The interaction between miR-744-5p and LINC01116 (or SCN1B) was confirmed by RNA pull down and luciferase reporter assays. RESULTS LINC01116 was up-regulated in LUSC tissues and cells, and LINC01116 repression limited the proliferative, migratory, invasive capabilities and EMT process in LUSC cells. In mechanism, LINC01116 directly interacted with miR-744-5p, and its expression was negatively correlated with miR-744-5p expression. SCN1B, overexpressed in LUSC tissues and cells, was proved to be targeted by miR-744-5p. Furthermore, SCN1B expression was in a negative association with miR-744-5p expression. At last, SCN1B amplification recovered the inhibitive effect of LINC01116 knockdown on cell proliferation, migration, invasion and EMT process in LUSC. CONCLUSION LINC01116 regulated miR-744-5p/SCN1B axis to exacerbate LUSC, providing a helpful theoretic basis for the exploration of LUSC treatment.

Abstract
BACKGROUND A growing number of studies have shown that circular RNA (circRNA) is an important regulator molecule in cancer progression, but it has been poorly studied in diffuse large b-cell lymphoma (DLBCL). OBJECTIVE This study aimed to explore the role of circ_OTUD7A in DLBCL. METHODS Relative expression levels of circ_OTUD7A, microRNA (miR)-431-5p and forkhead box P1 (FOXP1) were determined by quantitative real-time PCR (qRT-PCR). The proliferation of cells was elevated by colony formation assay and MTT assay. Western blot (WB) analysis was employed to measure the protein levels of proliferation marker, epithelial-mesenchymal transition (EMT) markers, cyclin marker, apoptosis markers and FOXP1. Moreover, the apoptosis, cell cycle process, migration and invasion of cells were detected using flow cytometry and transwell assay, respectively. In addition, the interaction between miR-431-5p and circ_OTUD7A or FOXP1 was confirmed by dual-luciferase reporter assay. RESULTS Circ_OTUD7A was highly expressed in DLBCL, and its knockdown could inhibit DLBCL cell proliferation and metastasis, while promote cell cycle arrest and apoptosis. Similarly, FOXP1 also was upregulated in DLBCL, and its silencing could restrain the progression of DLBCL cells. Further experiments revealed that circ_OTUD7A could sponge miR-431-5p and miR-431-5p could target FOXP1. MiR-431-5p inhibitor could reverse the suppressive effect of circ_OTUD7A silencing on DLBCL progression, and FOXP1 overexpression also could reverse the inhibitory effect of miR-431-5p mimic on DLBCL progression. CONCLUSION Circ_OTUD7A promoted the progression of DLBCL by regulating the miR-431-5p/FOXP1 axis, which suggested that circ_OTUD7A might function as an oncogene in DLBCL.

Abstract
Diabetic vascular complications are the leading causes of death and disability in patients with diabetes. Alpha-mangostin has been reported to have anti-diabetic capacity in recent years. Here, we investigated the protective function of alpha-mangostin on endothelium in vitro and in vivo experiments. We also observed that alpha-mangostin improved impaired endothelium-dependent vasodilation (EDV) of diabetic animals while it limited the aSMase/ceramide pathway and up-regulated eNOS/NO pathway in aortas from diabetic mice. Meanwhile, alpha-mangostin inhibited elevated aSMase/ceramide pathway and reversed impaired EDV induced by high glucose in isolated mouse aortas. In addition, alpha-mangostin increased phosphorylation of eNOS and NO production in high glucose-treated aortas. Alpha-mangostin normalized high glucose-induced activation of aSMase/ceramide pathway and improved eNOS/NO pathway in endothelial cells with high glucose. In conclusion, alpha-mangostin regulates eNOS/NO pathway and improves EDV in aortas of diabetic mice through inhibiting aSMase activity and endogenous ceramide accumulation.

Abstract
BACKGROUND Lung cancer is considered to be the first place among the cancer-related deaths worldwide and demands novel strategies in the treatment of this life-threatening disorder. The aim of this review is to explore regulation of epithelial-to-mesenchymal transition (EMT) by long non-coding RNAs (lncRNAs) in lung cancer. INTRODUCTION LncRNAs can be considered as potential factors for targeting in cancer therapy, since they regulate a bunch of biological processes, e.g. cell proliferation, differentiation and apoptosis. The abnormal expression of lncRNAs occurs in different cancer cells. On the other hand, epithelial-to-mesenchymal transition (EMT) is a critical mechanism participating in migration and metastasis of cancer cells. METHOD Different databases including Googlescholar, Pubmed and Sciencedirect were used for collecting articles using keywords such as "LncRNA", "EMT", and "Lung cancer". RESULT There are tumor-suppressing lncRNAs that can suppress EMT and metastasis of lung cancer cells. Expression of such lncRNAs undergoes down-regulation in lung cancer progression and restoring their expression is of importance in suppressing lung cancer migration. There are tumor-promoting lncRNAs triggering EMT in lung cancer and enhancing their migration. CONCLUSION LncRNAs are potential regulators of EMT in lung cancer, and targeting them, both pharmacologically and genetically, can be of importance in controlling migration of lung cancer cells.

Abstract
BACKGROUND Long non-coding RNAs (lncRNA) have emerged as novel clinical biomarkers and therapeutic targets for various tumors because of their disease- and stage-restricted expression. lncRNA FBXL19 antisense RNA 1 (FBXL19-AS1) expression has been confirmed to be up-regulated in several tumors. However, its expression and effects in paediatric acute myeloid leukemia (AML) have not been elucidated. METHODS Serum FBXL19-AS1 expression was determined in 137 AML patients compared to 43 healthy controls ( < 0.01). RESULTS Using receiver operating characteristic curve analysis, we observed that serum FBXL19-AS1 provided the highly diagnostic performance for the detection of AML (AUC = 0.841, < 0.001). We also examined the association between serum FBXL19-AS1 expression and clinicopathological factors, finding that its high expression was associated with French-American-British classification ( = 0.011) and cytogenetics ( = 0.021). Survival assays with the Kaplan-Meier method revealed that the overall survival ( = 0.0088) and disease-free-survival ( = 0.0027) of AML patients with high serum FBXL19-AS1 levels were distinctly shorter compared to those with low serum FBXL19-AS1 levels. More importantly, Multivariate analysis identified serum FBXL19-AS1 overexpression as an independent unfavorable prognostic factor for both overall survival and disease-free-survival of AML patients. CONCLUSIONS Overall, our findings revealed that high expression of serum FBXL19-AS1 might be useful as a novel prognostic and diagnostic biomarker for AML patients.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common neoplastic diseases worldwide. Available biomarkers are not sensitive enough for the diagnosis of HCC, hence seeking new biomarkers of HCC is urgent and challenging. The purpose of this study was to investigate the role of F-box and leucine-rich repeat protein 19-antisense RNA 1 (FBXL19-AS1) through a functional network and inquire into its diagnostic and prognostic value in HCC. A comprehensive strategy of genomic data mining, bioinformatics and experimental validation was used to evaluate the clinical value of FBXL19-AS1 in the diagnosis and prognosis of HCC and to identify the pathways in which FBXL19-AS1 might be involved. FBXL19-AS1 was up-regulated in HCC tissues, and its high expression was associated with TNM stage and poor prognosis of HCC patients. The combination of FBXL19-AS1 and alpha-fetoprotein (AFP) in plasma could prominently improve the diagnostic validity for HCC. FBXL19-AS1 might stabilize FBXL19 to reduce the amount of macrophage M1, and then promote the occurrence and development of HCC. Meanwhile, FBXL19-AS1 might participate in regulating HCC related pathways through FBXL19-AS1-miRNA-mRNA network. Our findings indicated that FBXL19-AS1 not only serves as a potential biomarker for HCC diagnosis and prognosis, but also might be functionally carcinogenic.

Abstract
BACKGROUND miR-431-5p is dysregulated in various cancers and plays an important function in the development of cancer. However, its role in fibroblast-like synoviocytes (FLSs) in patients with rheumatoid arthritis (RA) remains to be understood. METHODS Quantitative real-time polymerase chain reaction was used to detect the relative expression of miR-431-5p in synovial tissues and FLSs. Cell proliferation assays helped examine RA FLS proliferation. Flow cytometry was performed to determine apoptosis and cell cycle progression in RA FLSs. We used dual-luciferase assays to determine the correlation between miR-431-5p and its putative target, X-linked inhibitor of apoptosis (XIAP). Quantitative real-time PCR and western blotting were used to measure XIAP levels in synovial tissues and transfected RA FLSs. RESULTS miR-431-5p was downregulated in synovial tissues and FLSs of patients with RA. Upregulation of miR-431-5p prohibited cell proliferation and the G0/G1-to-S phase transition but promoted apoptosis in RA FLSs, while miR-431-5p inhibition showed the opposite results. miR-431-5p directly targeted XIAP in RA FLSs and reversely correlated with XIAP levels in synovial tissues. Notably, XIAP silencing partially restored the effects of miR-431-5p inhibition in RA FLSs. CONCLUSION miR-431-5p regulates cell proliferation, apoptosis, and cell cycle of RA FLSs by targeting XIAP, suggesting its potential in the treatment of RA.

[PMID: 32992718 PMCID: PMC7711482 DOI: 10.3390/ncrna6040042] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 09/21/2020] [Accepted: 09/23/2020] [Indexed: 12/30/2022] Open
Abstract
Long non-coding RNAs (lncRNAs) are defined as non-protein coding transcripts with a minimal length of 200 nucleotides. They are involved in various biological processes such as cell differentiation, apoptosis, as well as in pathophysiological processes. Numerous studies considered that frequently deregulated lncRNAs contribute to all hallmarks of cancer including metastasis, drug resistance, and angiogenesis. Angiogenesis, the formation of new blood vessels, is crucial for a tumor to receive sufficient amounts of nutrients and oxygen and therefore, to grow and exceed in its size over the diameter of 2 mm. In this review, the regulatory mechanisms of lncRNAs are described, which influence tumor angiogenesis by directly or indirectly regulating oncogenic pathways, interacting with other transcripts such as microRNAs (miRNAs) or modulating the tumor microenvironment. Further, angiogenic lncRNAs occurring in several cancer types such as liver, gastrointestinal cancer, or brain tumors are summarized. Growing evidence on the influence of lncRNAs on tumor angiogenesis verified these transcripts as potential predictive or diagnostic biomarkers or therapeutic targets of anti-angiogenesis treatment. However, there are many unsolved questions left which are pointed out in this review, hence driving comprehensive research in this area is necessary to enable an effective use of lncRNAs as either therapeutic molecules or diagnostic targets in cancer.

Abstract
Background Hepatocellular carcinoma (HCC) is a common lethal malignant tumor worldwide. Circular RNAs (circRNAs) have been reported to affect the development of human cancers, including HCC. In this project, we aim to clarify the functional effect of circular CDR1as (circ_CDR1as) on HCC progression. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) or Western blot is implemented to detect the expression of circ_CDR1as, microRNA (miR)-1287 and Raf-1 proto-oncogene, serine/threonine kinase (Raf1). Cell proliferation is assessed via colony formation and 3-(4, 5)-dimethylthiazole-2-y1)-2, 5-biphenyl tetrazolium bromide (MTT) assays. Cell migration and invasion are measured by Transwell assay. The target relationship between miR-1287 and circ_CDR1as or Raf1 is validated through dual-luciferase reporter assay. The levels of epithelia–mesenchymal transition (EMT) markers and the MEK/ERK signal pathway-related proteins are examined by Western blot. Model in nude mice is constructed to determine the role of circ_CDR1as in vivo. Results Expression of circ_CDR1as and Raf1 is elevated, while miR-1287 expression is decreased in HCC. Depletion of circ_CDR1as or Raf1 could inhibit proliferation and metastasis of HCC cells. Besides, circ_CDR1as regulates Raf1 expression by targeting miR-1287. MiR-1287 upregulation or Raf1 depletion could partially counterbalance circ_CDR1as depletion-mediated inhibitory effects on HCC cell behaviors. Moreover, circ_CDR1as depletion represses HCC progression through inactivating MEK/ERK pathway. In addition, circ_CDR1as depletion suppresses tumor growth in vivo via regulating miR-1287/Raf1 pathway. Conclusion Circ_CDR1as depletion inhibits HCC cell proliferation and metastasis by miR-1287/Raf1 and MEK/ERK pathways, highlighting a promising molecular target for HCC treatment.

Abstract
Papillary thyroid cancer (PTC) is a frequent thyroid malignancy. With the significant regulatory role in tumor progression, more attention has been employed to investigate mechanism of long noncoding RNAs (lncRNAs) in progression of PTC. We prospectively explored the mechanism whereby lncRNA SET-binding factor 2-antisense RNA1 (SBF2-AS1) is implicated in pathogenesis of PTC. First, differentially expressed SBF2-AS1 between PTC and normal adjacent thyroid tissues was determined, and result indicated a higher SBF2-AS1 expression in PTC tissues than adjacent normal tissues. Moreover, highly SBF2-AS1 expression predicted a poor prognosis in PTC patients. Second, SBF2-AS1 overexpression promoted cell viability and cycle of PTC, while inhibited cell apoptosis. However, SBF2-AS1 downregulation reduced viability and cycle, while promoted cell apoptosis. Moreover, SBF2-AS1 could bind with miR-431-5p and showed negative correlation with miR-431-5p in PTC patients. Furthermore, miR-431-5p bind with cyclin-dependent kinase (CDK) 14 and showed negative correlation with CDK14 in PTC patients. Finally, overexpression of CDK14 counteracted with the inhibitory role of SBF2-AS1 downregulation on cell viability, cycle, and apoptosis of PTC. In conclusion, SBF2-AS1 exhibited oncogenic property in PTC, and knockdown of SBF2-AS1 could be a therapeutic strategy for PTC.

Abstract
Lung cancer ranks topmost among the most frequently diagnosed cancers. Despite increasing research, there are still unresolved mysteries in the molecular mechanism of lung cancer. Long noncoding RNA small nucleolar RNA host gene 11 (SNHG11) was found to be upregulated in lung cancer and facilitated lung cancer cell proliferation, migration, invasion, and epithelial-mesenchymal transition progression while suppressed cell apoptosis. Moreover, the high expression of SNHG11 was correlated with poor prognosis of lung cancer patients, TNM stage, and tumor size. Further assays demonstrated that SNHG11 functioned in lung cancer cells via Wnt/β-catenin signaling pathway. Subsequently, Wnt/β-catenin pathway was found to be activated through SNHG11/miR-4436a/CTNNB1 ceRNA axis. As inhibiting miR-4436 could only partly rescue the suppression of cell function induced by silencing SNHG11, it was suspected that β-catenin might enter cell nucleus through other pathways. Mechanism investigation proved that SNHG11 would directly bind with β-catenin to activate classic Wnt pathway. Subsequently, in vivo tumorigenesis was also demonstrated to be enhanced by SNHG11. Hence, SNHG11 was found to promote lung cancer progression by activating Wnt/β-catenin pathway in two different patterns, implying that SNHG11 might contribute to lung cancer treatment by acting as a therapeutic target.

Abstract
Lung cancer is the most frequently diagnosed malignancy and the leading source of cancer-associated mortality. This kind of cancer has heterogeneous nature and is divided into two broad classes of small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). In addition to aberrant expression of several signaling pathways and oncogenes, lung cancer is associated with dysregulation of expression of non-coding RNAs including both long non-coding RNAs (lncRNAs) and miRNAs. These aberrantly expressed transcripts are putative therapeutic targets and diagnostic/ prognostic markers. Integrative assessment of expression of lncRNAs, miRNAs and mRNAs has led to construction of competing endogenous RNA networks in which several lncRNAs act as molecular sponges to inhibit regulatory function of miRNAs on mRNAs. Notably, some of these networks seem to have subtype-specific functions in lung cancer. In this review, we summarize recent findings about the importance of these networks in the pathogenesis of lung cancer and provide a list of onco-miRNAs, tumor suppressor miRNAs, oncogenic lncRNAs and tumor suppressor lncRNAs based on their roles in the carcinogenic process in lung cancer.

Abstract
Background Glioma is one of the most widely diagnosed malignancies worldwide. It has been reported that long noncoding RNAs (lncRNAs) are participators in the tumorgenesis of cancers. Nevertheless, the role and function of lncRNA SNHG17 among glioma is unclear. Methods RT-qPCR revealed SNHG17, YY1, miR-506-3p, CTNNB1 expression among glioma cells. CCK-8, colony formation, EdU, flow cytometry, TUNEL and western blot assays revealed the function of SNHG17 in glioma. RIP uncovered SNHG17, miR-506-3p and CTNNB1 enrichment in RISC complex. Luciferase reporter assays and RNA pull down revealed interaction of miR-506-3p with SNHG17 and CTNNB1. Results SNHG17 expression was up-regulated in glioma tissues and cells. SNHG17 silence attenuated cell proliferation and promoted apoptosis and repressed tumor growth. Moreover, SNHG17 was up-regulated by transcription factor YY1. Mechanistically, SNHG17 activated Wnt/β-catenin signaling pathway in glioma. CTNNB1 was referred to as the mRNA of β-catenin, we validated that SNHG17 bound to miR-506-3p to induce CTNNB1 and activate Wnt/β-catenin signaling pathway. Rescue experiments indicated that CTNNB1 overexpression abolished the inhibitory effects of SNHG7 inhibition on glioma progression. Conclusions The findings that YY1-induced SNHG17 facilitated the glioma progression through targeting miR-506-3p/CTNNB1 axis to activate Wnt/β-catenin signaling pathway offered a brand-new prospects to molecular-targeted treatment for glioma.

Abstract
Background Papillary thyroid cancer (PTC) is the most common malignancy of all thyroid cancers. LncRNA LINC00460 has been proved to play roles in the oncogenesis and progression of various tumors, including papillary thyroid cancer. However, the potential molecular mechanism of LINC00460 in PTC is poorly investigated. Results LINC00460 was upregulated in PTC tissues and cells. Raf1 was upregulated in PTC tissues, but miR-485-5p was down-regulated. High LINC00460 expression was associated with poor prognosis. LINC00460 knockdown suppressed proliferation, migration, invation and EMT of PTC cells. Bioinformatics prediction revealed that LINC00460 had binding sites with miR-485-5p, which was validated by luciferase reporter assay. In addition, miR-485-5p was confirmed to directly target Raf1 3′-UTR. Moreover, LINC00460 promoted PTC progression by sponging miR-485-5p to elevate the expression of Raf1. Knockdown of LINC00460 restrained tumor growth in vivo. Conclusion LINC00460 induced proliferation, migration, invation and EMT of PTC cells by regulating the LINC00460/miR-485-5p/Raf1 axis, which indicated that LINC00460 may be a potential biomarker and therapeutic target for PTC.

Abstract
Breast cancer has become an important public health problem. Moreover, the functions of microRNA-431 (miR-431) have been detected in human cancers other than breast cancer. Hence, we investigated the role of miR-431 in progression of breast cancer. RT-qPCR and Western blot analysis were performed to assess expression of miR-431 and genes. The regulatory mechanism of miR-431 was investigated using MTT, Transwell and luciferase reporter assay. Decreased miR-431 expression was identified in breast cancer, which was related to aggressive behavior. Furthermore, miR-431 restrained cell proliferation, metastasis and EMT in breast cancer. miR-431 induced apoptosis through enhancing Bax expression. In addition, miR-431 was found to directly target FGF9. Moreover, upregulation of FGF9 impaired the anti-tumor effect of miR-431 in breast cancer. miR-431 restrained cell viability and metastasis in breast cancer through targeting FGF9, indicating that miR-431 serves as a tumor inhibitor in breast cancer.

Acta Biochim Biophys Sin (Shanghai) 2019; 51:1106-1113. [PMID: 31696201 DOI: 10.1093/abbs/gmz110] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 06/17/2019] [Accepted: 09/02/2019] [Indexed: 12/14/2022] Open
Abstract
As the most common cancer and one of the leading causes of cancer-associated mortality, breast cancer continues to need more key molecules to regulate its progression. F-box and leucine-rich repeat protein 19 antisense RNA 1 (known as FBXL19-AS1) is a long non-coding RNA (lncRNA) which has been reported as an oncogene in several types of human cancers. However, the specific downstream targets of FBXL19-AS1 remain unknown. In this study, we set out to find more reliable downstream molecules of FBXL19-AS1 in breast cancer. FBXL19-AS1 was expressed at a high level in breast cancer cells. Loss-of-function experiments revealed that silencing FBXL19-AS1 could impair cell proliferation and induce cell apoptosis in breast cancer. In addition, the location of FBXL19-AS1 in the cytoplasm was detected by fluorescent in situ hybridization assay, while FBXL19-AS1 regulated the expression of Forkhead box M1 (FOXM1) by directly absorbing miR-876-5p. Through rescue assays, it was observed that FOXM1 overexpression recovered the inhibited tumor growth caused by FBXL19-AS1 downregulation. We affirmed the function of FBXL19-AS1 in breast cancer and described the mechanism of the FBXL19-AS1/miR-876-5p/FOXM1 axis. The current work presents the molecular mechanism which underlies FBXL19-AS1 in breast cancer and suggests a comprehensive, feasible FBXL19-AS1-mediated therapeutic approach for treating breast cancer.

[PMID: 31703640 PMCID: PMC6842182 DOI: 10.1186/s12885-019-6269-x] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2019] [Accepted: 10/15/2019] [Indexed: 01/10/2023] Open
Abstract
Background In past decades, circular RNAs (circRNAs) have achieved increasing attention because of its regulatory role in different kinds of cancers. However, how circAGFG1 regulates cervical cancer (CC) is still largely undiscovered. This study aims to evaluate the role of a novel circRNAs and related molecular mechanism in CC cells. Methods High or low level of circAGFG1 was detected in CC cells or normal cell line with qRT-PCR. The proliferative and migratory abilities of CC cells were assessed with loss-of function assays. The downstream miRNA and mRNA of circAGFG1 were searched out and proved by using bioinformatics analysis and mechanism experiments. Recue assays were designed to confirm the role of circAGFG1/miR-370-3p/RAF1 axis in CC cell activities. Results The levels of circAGFG1 was abundant in CC cells in comparison with normal cervical cell End1/E6E7. The inhibitory effect of decreased circAGFG1 level on the proliferative and migratory abilities of CC cells was assessed. CircAGFG1 and miR-370-3p were localized in the cytoplasm and they can interact with each other. Moreover, miR-370-3p was downregulated in CC cells. We also determined the negative effect of miR-370-3p on RAF1. CircAGFG1 could promote RAF1 expression by absorbing miR-370-3p, thereby activating RAF/MEK/ERK pathway. circAGFG1 promoted proliferation and migration of CC cells via enhancing the activity of RAF/MEK/ERK pathway by sponging miR-370-3p and further regulating RAF1. Conclusion The results of this study provided new evidence that circAGFG1 acted as a vital regulator in cervical cancer proliferation and migration, giving great promise to apply it as a potential biomarker for diagnosis and therapy in CC treatment.

Abstract
The pivotal roles of long noncoding RNAs have been reported in various cancers. Recently, FBXL19-AS1 was proposed to be involved in tumor progression. However, its role in lung adenocarcinoma (LUAD) remains elusive. In this study, we observed that FBXL19-AS1 was significantly upregulated in LUAD tissues and high FBXL19-AS1 expression in LUAD was associated with a poor prognosis. Nevertheless, miR-203-3p showed the opposite effect. Moreover, cell viability and apoptosis analysis revealed that FBXL19-AS1 knockdown could arrest LUAD cells in G0/G1 phase and inhibit cell proliferation, migration and invasion in vitro and inhibited LUAD tumor progress in vivo. Mechanistically, we identified FBXL19-AS1 could act as a miR-203a-3p sponge using dual-luciferase reporter assay. In addition, we demonstrated that downregulation of miR-203a-3p reversed growth inhibition of LUAD cells caused by FBXL19-AS1 knockdown. Finally, FBXL19-AS1/miR-203a-3p axis was found to associate with baculoviral IAP repeat-containing protein 5.1-A-like (survivin), distal-less homeobox 5, E2F transcription factor 1, and zinc finger E-box binding homeobox 2 to regulate metastasis in LUAD cells. This study reveals a significance and mechanism of FBXL19-AS1 in LUAD proliferation and metastasis and offers a potential prognostic marker and a therapeutic target for patients with LUAD.
