Ma JJ, Xiang C, Zhu HQ, Bai BL, Wang P, Zhao GA. Expression and prognosis analysis of integrin subunit α3 (ITGA3) in papillary thyroid cancer. Heliyon 2024; 10:e23163. [PMID: 38163190 PMCID: PMC10756987 DOI: 10.1016/j.heliyon.2023.e23163] [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: 01/30/2023] [Revised: 11/23/2023] [Accepted: 11/28/2023] [Indexed: 01/03/2024] Open
Abstract
Integrin subunit α3 (ITGA3) is a member of the integrin family and interacts with extracellular matrix proteins. However, there have been few reports regarding the role of ITGA3 in papillary thyroid cancer. The expression levels of ITGA3 were firstly analyzed by bioinformatics tools and in vitro experiments, followed by evaluating its prognostic significance in papillary thyroid cancer patients using Kaplan-Meier, receiver operating characteristic, and Cox regression analyses. Then, cBioportal and GSCA databases were applied to evaluate genetic alterations of ITGA3. Functional enrichment analysis was conducted and the upstream miRNAs of ITGA3 were determined. The results showed that the ITGA3 mRNA and protein levels were higher in the papillary thyroid cancer group than those in the normal group (all P < 0.05). Moreover, ITGA3 performed well in distinguishing the recurrence-free survival (RFS) status and served as an independent prognostic factor of papillary thyroid cancer patients (P < 0.01). Besides, significant relations between ITGA3 and genetic alterations were observed (FDR <0.01). Functional enrichment analysis indicated ECM-receptor interaction and cell adhesion molecules were the shared regulatory pathways. Moreover, ITGA3 might be the target gene of hsa-miR-3129, hsa-miR-181d, hsa-miR-181b, hsa-miR-199a, and hsa-miR-199b. Of note, the ITGA3 mRNA level was reduced after has-miR-199b-3p/5p was overexpressed. In conclusion, ITGA3 could be a reliable biomarker and have potential value in predicting the RFS status of papillary thyroid cancer patients.

Abstract
Multiple myeloma (MM) is a cancer of plasma cells that has been extensively studied in recent years, with researchers increasingly focusing on the role of microRNAs (miRNAs) in regulating gene expression in MM. Several non-coding RNAs have been demonstrated to regulate MM pathogenesis signaling pathways. These pathways might regulate MM development, apoptosis, progression, and therapeutic outcomes. They are Wnt/β-catenin, PI3K/Akt/mTOR, P53 and KRAS. This review highlights the impending role of miRNAs in MM signaling and their relationship with MM therapeutic interventions.

Abstract
Thyroid cancer (TC) is the most prevalent endocrine malignant tumor. It has many types, the Papillary thyroid cancer (PTC)(most common and follicular thyroid carcinoma (FTC). Several risk factors have been associated with TC radiation exposure, autoimmunity, and genetics. Microribonucleic acids (miRNAs) are the most important genetic determinants of TC. They are small chains of nucleic acids that are able to inhibit the expression of several target genes. They could target several genes involved in TC proliferation, angiogenesis, apoptosis, development, and even resistance to therapy. Besides, they could influence the stemness of TC. Moreover, they could regulate several signaling pathways such as WNT/β-catenin, PI3K/AKT/mTOR axis, JAK/STAT, TGF- β, EGFR, and P53. Besides signaling pathways, miRNAs are also involved in the resistance of TC to major treatments such as surgery, thyroid hormone-inhibiting therapy, radioactive iodine, and adjuvant radiation. The stability and sensitivity of several miRNAs might be exploited as an approach for the usage of miRNAs as diagnostic and/or prognostic tools in TC.

BMC Cancer 2022; 22:909. [PMID: 35986311 PMCID: PMC9392259 DOI: 10.1186/s12885-022-09996-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Accepted: 08/10/2022] [Indexed: 11/13/2022] Open
Abstract
Background HuR/ELAVL1 (embryonic lethal abnormal vision 1) was a downstream target of miR-29b in some cancer cells. HuR protein exerts important prognostic effects of involving in the pathogenesis and development of acute myeloid leukemia (AML). This study aims to investigate the role of miR-29b-3p in biological behaviors of AML cells by targeting HuR and the involvement of the NF-κB and JAK/STAT signaling pathways. Methods The expressions of HuR and miR-29b-3p in AML cells were determined using RT-qPCR and Western blot, and the association between them was analyzed using the Spearman method. Next, the target relationship between HuR and miR-29b-3p was predicted by biological information databases and verified by the dual-luciferase reporter gene assay. MTS, methyl cellulose, flow cytometry and transwell assay were employed to detect the cell proliferation, clone formation, cell cycle and apoptosis, invasion and migration respectively, the effect of miR-29b-3p targeted HuR on the biological behaviors of AML cells was explored after over- /down-expression of miR-29b-3p and rescue experiment. Then, immunofluorescence assay and western blot were employed to detect location expression and phosphorylation levels of NF-κB and JAK/STAT signaling pathways related molecules respectively. Results HuR was negatively correlated with miR-29b-3p, and was the downstream target of miR-29b-3p in AML cells. When miR-29b-3p was overexpressed in AML cells, HuR was down-regulated, accompanied by cell viability decreased, cell cycle arrest, apoptosis increased, invasion and migration weakened. Moreover, the opposite result appeared after miR-29b-3p was down-regulated. The rescue experiment showed that miR-29b-3p inhibitor could reverse the biological effect of HuR down-regulation in AML cells. Molecular pathway results showed that miR-29b-3p could inhibit p65 expression in nucleus and phosphorylation levels of p65, IκBα, STAT1, STAT3 and STAT5. Conclusion miR-29b-3p can inhibit malignant biological behaviors of AML cells via the inactivation of the NF-κB and JAK/STAT signaling pathways by targeting HuR. miR-29b-3p and its target HuR can be used as a new potential molecular for AML treatment.

Abstract
miR-520a-3p is downregulated and MUC1 is upregulated in AML patients. miR-520a-3p over-expression inhibits AML cell proliferation, accelerates apoptosis, and inhibits AML tumor growth. miR-520a-3p targets MUC1 and negatively regulates its expression. MUC1 knockdown supresses AML cell proliferation and promotes apoptosis. miR-520a-3p overexpression inhibits AML cell proliferation and accelerates cell apoptosis via regulating MUC1/Wnt/β-catenin axis.
Background Acute myeloid leukemia (AML) is one of the familiar malignant tumors in the hematological system. miR-520a-3p is reported to be involved in several cancers’ progression. However, miR-520a-3p role in AML remains unclear. In this study, we aimed to clarify the role and potential mechanism of miR-520a-3p in AML. Methods Cell viability, proliferation, cycle and apoptosis were detected by MTT assay, colony formation assay, flow cytometry, respectively. The levels of PNCA, Bcl-2, Cleaved caspase 3, Cleaved caspase 9 and β-catenin protein were detected by Western blot. Dual-luciferase reported assay was performed to detect the regulation between miR-520a-3p and MUC1. To verify the effect of miR-520a-3p on tumor proliferation in vivo, a non-homogenous transplant model of tumors was established. Results miR-520a-3p expression was down-regulated, and MUC1 expression was up-regulated in AML patients. miR-520a-3p overexpression suppressed THP-1 cell proliferation, induced cell cycle G0/G1 inhibition and promoted apoptosis. miR-520a-3p targeted MUC1 and negatively regulated its expression. MUC1 knockdown inhibited THP-1 cell proliferation and promoted apoptosis. miR-520a-3p overexpression inhibited AML tumors growth. Conclusion Overexpression miR-520a-3p inhibited AML cell proliferation, and promoted apoptosis via inhibiting MUC1 expression and repressing Wnt/β-catenin pathway activation.

Abstract
In this study, mRNA expression of gastric cancer tissue and clinical data of patients in TCGA-STAD dataset were used, together with the hypoxia-related gene sets in the MsigDB database, to screen hypoxia-related differentially expressed genes (DEGs) in GC. Thereafter, univariate and multivariate Cox regression analyses were carried out on hypoxia-related DEGs. The optimal feature genes related to prognosis were obtained to construct a prognostic risk assessment model. According to the model, the riskScore of GC patients was measured, and GC samples were assigned into high- and low-risk groups in accordance with the median riskScore. Based on the Kaplan-Meier curve and Receiver operating characteristic curve, validity of the prognostic risk assessment model was measured. Gene set enrichment analysis was performed on the two risk groups through Gene set enrichment analysis software. The results revealed that in the high-risk group, 9 signaling pathways were remarkably activated in several terms, like focal adhesion, extracellular matrix receptor interaction, Cell adhesion molecules cams, Cytokine-cytokine receptor interaction, TGF-beta signaling pathway, NOD-like receptor signaling pathway, JAK-STAT signaling pathway, Toll-like receptor signaling pathway and MAPK signaling pathway. In combination with riskScore and clinical factors, univariate and multivariate Cox regression analyses verified the independence of the model. Meanwhile, a nomogram was constructed to predict the 1-, 3- and 5-year survival of GC patients. The calibration curve indicated that the survival status predicted by the nomogram fitted better with actual survival status. On the whole, the prognostic risk model of GC on the basis of hypoxia-related genes demonstrated good predictive ability. It can provide more powerful technical support for clinicians to make prognostic determination and therapeutic plans.

Abstract
Thyroid cancer (TC) is one of the most frequent endocrine malignancies that is more common among females. Tumor recurrence is one of the most important clinical manifestations in differentiated TC which is associated with different factors including age, tumor size, and histological features. Various molecular processes such as genetic or epigenetic modifications and non-coding RNAs are also involved in TC progression and metastasis. The epithelial-to-mesenchymal transition (EMT) is an important biological process during tumor invasion and migration that affects the initiation and transformation of early-stage tumors into invasive malignancies. A combination of transcription factors, growth factors, signaling pathways, and epigenetic regulations affect the thyroid cell migration and EMT process. MicroRNAs (miRNAs) are important molecular factors involved in tumor metastasis by regulation of EMT-activating signaling pathways. Various miRNAs are involved in the signaling pathways associated with TC metastasis which can be used as diagnostic and therapeutic biomarkers. Since, the miRNAs are sensitive, specific, and non-invasive, they can be suggested as efficient and optimal biomarkers of tumor invasion and metastasis. In the present review, we have summarized all of the miRNAs which have been significantly involved in thyroid tumor cells migration and invasion. We also categorized all of the reported miRNAs based on their cellular processes to clarify the molecular role of miRNAs during thyroid tumor cell migration and invasion. This review paves the way of introducing a non-invasive diagnostic and prognostic panel of miRNAs in aggressive and metastatic TC patients.

Abstract
Papillary thyroid cancer (PTC) accounts for about 90% of thyroid cancer. There are approximately 20%-30% of PTC patients showing disease persistence/recurrence and resistance to radioactive iodine (RAI) treatment. For these PTC patients with RAI refractoriness, the prognosis is poor. In this study, we aimed to establish a comprehensive prognostic model covering multiple signatures to increase the predictive accuracy for progression-free survival (PFS) of PTC patients with RAI treatment. The expression profiles of mRNAs and miRNAs as well as the clinical information of PTC patients were extracted from TCGA and GEO databases. A series of bioinformatics methods were successfully applied to filtrate a two-RNA model (IPCEF1 and hsa-mir-486-5p) associated with the prognosis of RAI-therapy. Finally, the RNA-based risk score was calculated based on the Cox coefficient of the individual RNA, which achieved good performances by the time-dependent receiver operating characteristic (tROC) curve and PFS analyses. Furthermore, the predictive power of the nomogram, integrated with the risk score and clinical parameters (age at diagnosis and tumor stage), was assessed by tROC curves. Collectively, our study demonstrated high precision in predicting the RAI response of PTC patients.

Abstract
Background Long noncoding RNA (lncRNA) SET-binding factor 2 (SBF2) antisense RNA1 (SBF2-AS1), which acts as an oncogene in various cancers, can promote tumors progression. The study aimed to explore the role and molecular mechanism of SBF2-AS1 in nonsmall cell lung cancer (NSCLC). Methods qRT-PCR was introduced to detect SBF2-AS1 and miR-520a-3p expression in NSCLC. The effects of SBF2-AS1 and miR-520a-3p on the proliferation, migration, and invasion of NSCLC cells were assessed through cell counting kit-8 (CCK-8) and transwell assay. Furthermore, the relationship of SBF2-AS1 and miR-520a-3p was verified by the RNA immunoprecipitation (RIP) assay, dual-luciferase assay, and Spearman correlation analysis. Results In NSCLC tissues, SBF2-AS1 was highly expressed, while miR-520a-3p expression has decreased. The overall survival of NSCLC patients with high SBF2-AS1 expression was lower. SBF2-AS1 silencing repressed the proliferation, migration, and invasion of NSCLC cells. SBF2-AS1 directly interacted with miR-520a-3p, and a negative relationship was observed between their expression levels in NSCLC tissues. More importantly, the suppression of SBF2-AS1 silencing on the proliferation, migration, and invasion in NSCLC cells was counteracted by miR-520a-3p inhibition. Conclusion SBF2-AS1 accelerated the proliferation, migration, and invasion of NSCLC cells via mediating miR-520a-3p, thus promoting NSCLC progression.

Abstract
BACKGROUND Studies have proven that as competing endogenous RNAs (ceRNAs), long non-coding RNAs (lncRNAs) play vital roles in regulating RNA transcripts in ischemic stroke. It has been reported that TTTY15, a lncRNA, is dysregulated in cardiomyocytes after ischemic injury. We intended to explore the potential regulating mechanism of TTTY15 in ischemic stroke. METHODS TTTY15 and miR-520a-3p levels in vivo were measured in the cerebral ischemia/reperfusion (I/R) model. Cell apoptosis was measured by flow cytometry. To manifest TTTY15 functions in I/R injury, Neuro 2a (N2a) cells were exposed to oxygen-glucose deprivation/reoxygenation (OGD/R) and treated with si-NC, pcDNA3.1-NC, si-TTTY15 or pcDNA3.1-TTTY15. RESULTS TTTY15 expression was elevated and miR-520a-3p expression was declined in mouse brains exposed to I/R and in N2a cells exposed to OGD/R. Bioinformatics analyses predicted the binding sites of miR-520a-3p in the 3'-UTRs of interferon regulatory factor 9 (IRF9) and TTTY15. Luciferase reporter assay exhibited that TTTY15 bound to miR-520a-3p directly and IRF9 was targeted by miR-520a-3p. MiR-520a-3p overexpression diminished N2a cell apoptosis caused by OGD/R. TTTY15 overexpression antagonized the inhibitory impacts of miR-520a-3p on IRF9 expression and apoptosis after OGD/R, while TTTY15 knockdown enhanced the inhibitory impacts of miR-520a-3p. Additionally, TTTY15 knockdown alleviated brain damages and neurological deficits induced by I/R in vivo. Our results revealed that TTTY15 modulated IRF9 via acting as a ceRNA for miR-520a-3p. CONCLUSION The study revealed the roles of TTTY15/miR-520a-3p/IRF9 signaling pathway in regulating cerebral ischemia/reperfusion injury.

Zhou H, Chen T. An integrated analysis of hypoxic-ischemic encephalopathy-related cell sequencing outcomes via genes network construction. IBRAIN 2022; 8:78-92. [PMID: 37786415 PMCID: PMC10529176 DOI: 10.1002/ibra.12025] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Revised: 02/04/2022] [Accepted: 02/06/2022] [Indexed: 10/04/2023]
Abstract
Hypoxic-ischemic encephalopathy (HIE) is one of the main causes of morbidity and severe neurological deficits in neonates. This study aimed to find core genes and their potential roles in HIE with the help of single-cell sequencing (SCS) technology and genes network construction. We collected and screened an HIE genes data set from the Pubmed database to analyze differential expression, and the differential values of genes were ≥3 or ≤-3 in gene expression. We constructed a protein-protein interaction (PPI) network by the string, which was also verified by Cytoscape 3.8.2. Functional enrichment analysis was performed to determine the characteristics and pathways of the core genes. We examined two meaningful papers and integrated all genes by SCS, which were classified into 12,093 genes without duplicates, 217 shared genes, and 11,876 distinct genes. Among 217 genes, the signal transducer and activator of transcription (STAT) family was the most targeted gene in the PPI network. Moreover, Gene Ontology and Kyoto encyclopedia of genes and genome analysis showed that the process in response to virus and the JAK-STAT signaling pathway play significant roles in HIE. We also found that 54 screened genes were highly expressed, while three genes (B2M, VIM, and MRPS30) were different in the heat map and differential genes expression exhibition. VIM, as an essential portion of the brain's cytoskeleton, is closely linked to STAT and neurologic development. From the findings of SCS and bioinformatics predictive analytics model, our outcomes provided a better understanding of the roles of STAT, the JAK-STAT signaling pathway, and VIM, which can pave an alternative avenue for further studies on HIE progression.

Abstract
PURPOSE To identify the expression of miR-520a-3p and AKT1 in non-small cell lung cancer cells (NSCLC) and the mechanism in inhibiting cell invasion and metastasis by targeting NF-kappaB signaling pathway. METHODS Bioinformatics analysis and dual luciferase reporter gene assay were used to predict and verify the targeting relationship between miR-520a-3p and AKT1. EdU assay was used to detect the proliferation of NSCLC cells. Flow cytometry detected the apoptosis of NSCLC cells. Transwell assay tested the invasion ability of NSCLC cells. qRT-PCR measured the expression of miR-520a-3p and AKT1 mRNA in NSCLC cells; while western blotting was adopted to detect the protein expressions of AKT1, Ki67, CyclinD1, Bax, Bcl-2, MMP-2, MMP-9, NF-kB p65, IkBs kinase (IKK), NF-kB inducing kinase (NIK). RESULTS Bioinformatics analysis suggested that miR-520a-3p could target AKT1. miR-520a-3p could regulate the expression of AKT1 negatively. Compared to mimic-NC group, miR-520a-3p mimic group had increased expressions of miR-520a-3p and Bax, while decreased expressions of AKT1, Ki67, CyclinD1, Bcl-2, MMP-2, MMP-9, NF-kB p65, IKK and NIK, reduced cell proliferation, invasion, and increased cell apoptosis rate (all P < 0.05). Compared to inhibitor NC group, miR-520a-3p inhibitor group had decreased expressions of miR-520a-3p and Bax, but increased expressions of AKT1, Ki67, CyclinD1, Bcl-2, MMP-2, MMP-9, NF-kB p65, IKK and NIK, promoted cell proliferation, invasion, and suppressed cell apoptosis rate (all P < 0.05). CONCLUSION Overexpression of miR-520a-3p can target and downregulate the expression of AKT1 to inhibit the invasion and metastasis of NSCLC via suppressing the activation of NF-kappaB signaling pathway.

Abstract
Cypermethrin (CYP), an extensively-used broad-spectrum pyrethroid pesticide, is regarded as a potential environmental endocrine disruptor with the anti-androgenic characteristic. To explore underlying roles of non-coding RNAs and the Jak/Stat pathway in CYP-mediated testosterone biosynthesis suppression, SD rats and Leydig cells were employed in this work. Results displayed that β-CYP decreased plasma testosterone levels and led to abnormal alterations of testicular histomorphology and ultrastructures. LncRNA XIST and miR-142-5p were co-localized in the cytoplasm of Leydig cells, but the expression of XIST was inhibited by β-CYP while that of miR-142-5p was induced. Then overexpressed miR-142-5p dampened the Jak1/Stat1 pathway by directly targeting Jak1. Transcription factors NFκB and YY1 impeded by β-CYP were positively regulated by the Jak1/Stat1 pathway. Bidirectional Co-IP and ChIP assays demonstrated that NFκB interacted with and modulated YY1 by directly binding to the promoter region of YY1. ChIP, qPCR, and YY1 knockdown/overexpression assays indicated that YY1 acted as a transcriptional activator to directly modulate steroidogenic StAR and 3β-HSD in Leydig cells. Taken together, miR-142-5p sponged by lncRNA XIST directly targets the Jak1/Stat1 pathway, which regulates steroidogenic StAR and 3β-HSD via NFκB and YY1, and ultimately dampens testosterone production in Leydig cells.

A network pharmacology approach to reveal the pharmacological targets and biological mechanism of compound kushen injection for treating pancreatic cancer based on WGCNA and in vitro experiment validation. Chin Med 2021; 16:121. [PMID: 34809653 PMCID: PMC8607619 DOI: 10.1186/s13020-021-00534-y] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 11/09/2021] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Compound kushen injection (CKI), a Chinese patent drug, is widely used in the treatment of various cancers, especially neoplasms of the digestive system. However, the underlying mechanism of CKI in pancreatic cancer (PC) treatment has not been totally elucidated. METHODS Here, to overcome the limitation of conventional network pharmacology methods with a weak combination with clinical information, this study proposes a network pharmacology approach of integrated bioinformatics that applies a weighted gene co-expression network analysis (WGCNA) to conventional network pharmacology, and then integrates molecular docking technology and biological experiments to verify the results of this network pharmacology analysis. RESULTS The WGCNA analysis revealed 2 gene modules closely associated with classification, staging and survival status of PC. Further CytoHubba analysis revealed 10 hub genes (NCAPG, BUB1, CDK1, TPX2, DLGAP5, INAVA, MST1R, TMPRSS4, TMEM92 and SFN) associated with the development of PC, and survival analysis found 5 genes (TSPOAP1, ADGRG6, GPR87, FAM111B and MMP28) associated with the prognosis and survival of PC. By integrating these results into the conventional network pharmacology study of CKI treating PC, we found that the mechanism of CKI for PC treatment was related to cell cycle, JAK-STAT, ErbB, PI3K-Akt and mTOR signalling pathways. Finally, we found that CDK1, JAK1, EGFR, MAPK1 and MAPK3 served as core genes regulated by CKI in PC treatment, and were further verified by molecular docking, cell proliferation assay, RT-qPCR and western blot analysis. CONCLUSIONS Overall, this study suggests that the optimized network pharmacology approach is suitable to explore the molecular mechanism of CKI in the treatment of PC, which provides a reference for further investigating biomarkers for diagnosis and prognosis of PC and even the clinical rational application of CKI.

Abstract
Thyroid cancer is the most common tumor arising from the endocrine system and generally presents good prognosis. However, its aggressive subtypes are related to therapeutic resistance and early metastasis. Epithelial–mesenchymal transition (EMT) and its reverse process, the mesenchymal–epithelial transition (MET), are key events mediating cancer progression, including in thyroid cancer. The matricellular protein osteopontin (OPN) has been reported as a master regulator of EMT in many tumor types. Although high OPN expression has been described and associated with important aspects of thyroid cancer progression, there is no clear evidence regarding OPN as a regulator of EMT in thyroid cancer. Thus, taking together the known roles of OPN in the modulation of EMT in cancer and the information reporting the expression of OPN in thyroid tumor progression, this review aims at summarizing and discussing data related to EMT in thyroid cancer and its putative relation to the roles of OPN in the development of thyroid cancer. These data provide new insights into the molecular mechanisms by which OPN could potentially modulate EMT in thyroid tumors, generating evidence for future studies that may contribute to new therapeutic, prognostic and/or diagnostic tools.

[PMID: 34435133 PMCID: PMC8354378 DOI: 10.1515/biol-2021-0072] [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: 11/23/2020] [Revised: 06/01/2021] [Accepted: 06/11/2021] [Indexed: 12/14/2022] Open
Abstract
Lidocaine can inhibit the malignant development of various human cancers. Circular RNA (circRNA) dynein 1 heavy chain gene (circ_DYNC1H1) acted as a pro-cancer molecule in hepatocellular carcinoma (HCC). This study aimed to explore whether the function of lidocaine was related to the oncogenic circ_DYNC1H1 in HCC. Colony formation assay and 3-(4,5-dimethylthiazol-2-y1)-2, 5-diphenyl tetrazolium bromide (MTT) assay were used for proliferation detection. Cell apoptosis was assessed by flow cytometry, and migration or invasion was determined by the transwell assay. The levels of circ_DYNC1H1, microRNA-520a-3p (miR-520a-3p), and ubiquitin-specific protease 14 (USP14) were examined using the quantitative reverse transcriptase polymerase chain reaction (qRT-PCR). Protein levels were measured using western blot. The binding between miR-520a-3p and circ_DYNC1H1 or USP14 was confirmed by the dual-luciferase reporter assay. In vivo assay was conducted by a xenograft model in mice. Lidocaine reduced proliferation, migration, and invasion but promoted apoptosis in HCC cells. The circ_DYNC1H1 expression was downregulated in lidocaine-treated HCC cells. The inhibitory effect of lidocaine on HCC progression was weakened after circ_DYNC1H1 overexpression. miR-520a-3p was a target of circ_DYNC1H1, and the function of lidocaine was related to the regulation of circ_DYNC1H1/miR-520a-3p axis. USP14 served as a target for miR-520a-3p, and circ_DYNC1H1 could sponge miR-520a-3p to regulate the USP14 expression. The lidocaine-induced suppression of HCC development was also achieved by mediating the miR-520a-3p/USP14 axis. In vivo assay revealed that lidocaine suppressed the tumor growth of HCC by reducing the expression of circ_DYNC1H1 to affect the levels of miR-520a-3p and USP14. Our results clarified that lidocaine impeded tumor progression via targeting the circ_DYNC1H1/miR-520a-3p/USP14 axis in HCC cells.

SLC34A2 Up-regulation And SLC4A4 Down-regulation Correlates With Invasion, Metastasis, And The MAPK Signaling Pathway In Papillary Thyroid Carcinomas. J Cancer 2021; 12:5439-5453. [PMID: 34405007 PMCID: PMC8364650 DOI: 10.7150/jca.56730] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Accepted: 06/28/2021] [Indexed: 12/27/2022] Open
Abstract
Papillary thyroid carcinoma (PTC) is one of the fastest growing endocrine system malignant carcinomas detected over the past decade. Unfortunately, more than 25% of PTC patients are characterized by their aggressiveness and subsequent metastasis; these characteristics usually indicate poor prognosis. Recently, increasing evidence has suggested that solute carrier (SLC) transporters may play a pivotal role in the initiation, invasion and metastasis of human carcinoma. However, the expression and clinicopathological significance of SLC transporters in patients with PTC remains undetermined. In this study, we aimed to elucidate how the differential expression of SLC transporters affects clinicopathological features, as well as determine the possible regulatory signaling pathways involved. Three differentially expressed SLC transporters were screened from the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) database using a bioinformatics approach. The results indicated that high SLC34A2 and low SLC4A4 protein expression exhibited a higher percentage of capsular invasion and extra-thyroid metastasis in patients. Logistic regression analysis showed that high SLC34A2 expression in tumors was identified as an independent risk factor for capsular invasion [odds ratio (OR)=11.400, 95% confidence interval (CI)=1.733-74.995, P=0.011] and extra-thyroid metastasis (OR=4.920, 95%CI=1.234-19.623, P=0.024), while low SLC4A4 expression in tumors was only identified as independent risk factors for extra-thyroid metastasis (OR=8.568, 95%CI =1.186-61.906, P=0.033). Specifically, for tumors with capsular invasion and extra-thyroid metastasis, the protein expression staining of SLC34A2 was markedly enhanced in the cytoplasm of follicular epithelial cells, contrastingly, SLC4A4 expression was notably weakened in the cytomembrane and nucleus. Intriguingly, both high SLC34A2 and low SLC4A4 protein expression were significantly linked to a high urinary iodine concentration in patients with PTC. Mechanistically, compared with adjacent normal thyroids, p-ERK was significantly up-regulated by 17.8% in the invading tumor; p-ERK, p-JNK, and p-P38 were markedly up-regulated by 29.2%, 67.1%, and 38.9% for metastatic tumors, respectively. Importantly, SLC4A4 negatively correlated with p-JNK (r=-0.696, P= 0.004) and p-P38 (r=-0.534, P=0.049). In conclusion, we suggest that up-regulated SLC34A2 (mainly in the cytoplasm) and down-regulated SLC4A4 (mainly in the cytomembrane and nucleus), which might be attributed to excess iodine intake, were closely linked to extra-thyroid metastasis in PTCs. Furthermore, this effect of SLC4A4 may be through the activation of JNK/P38 MAPK signaling pathway. Future in vivo and in vitro gain- or loss-of-function experiments are needed to verify these findings and further elucidate the deeper molecular mechanisms.

[PMID: 34296302 PMCID: PMC8317149 DOI: 10.3892/or.2021.8150] [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: 11/08/2020] [Accepted: 06/30/2021] [Indexed: 01/05/2023] Open
Abstract
The present study was designed to observe the expression of the centrosomal protein 63 in papillary thyroid cancer (PTC) tissues and cells and to explore the clinical significance of Cep63 expression in PTC. Primary PTC tissues and matched normal thyroid tissues were collected, and the Cep63 expression level was determined by reverse transcription-quantitative PCR and western blotting. A stable Cep63-knockout cell line was constructed to assess the proliferation, invasion, migration and apoptosis abilities in vitro. A subcutaneous tumorigenesis model was established in nude mice to evaluate the effect of Cep63 on tumor growth and proliferation in vivo. Western blotting was used to explore the relevant signaling pathways. The results revealed that the expression level of Cep63 in PTC tissues was significantly increased. The proliferation, invasion and migration abilities of TPC-1 cells were decreased after Cep63 knockout, and silencing of Cep63 resulted in TPC-1 cell cycle arrest in the S phase. Mechanistically, Cep63 knockout inhibited the activation of the Janus kinase/signal transducer and activator of transcription 3 signaling pathway. In conclusion, Cep63 knockout significantly inhibited biological functions of TPC-1 cells in vitro and in vivo, indicating that Cep63 may be an important oncogene of PTC.

[PMID: 34051007 DOI: 10.1002/cbin.11631] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 04/16/2021] [Accepted: 05/16/2021] [Indexed: 01/09/2023]
Abstract
Tripartite motif-containing protein 14 (TRIM14) is a tumor-promoter in papillary thyroid carcinoma (PTC). We found that miR-4443 expression was significantly downregulated in PTC tumor tissue, and was negatively associated with TRIM14. This study was designed to investigate the relationship between miR-4443 and TRIM14 on metastasis and energy metabolism in PTC and the underlying mechanisms. To this end, human PTC cells (SW1736 and MZ-CRC-1) were transfected with a miR-4443 mimic or miR-4443 inhibitor + siRNA-TRIM14, and then dual-luciferase assay, Transwell, Seahorse, and western blot analyses were performed to assess the function of miR-4443 and the underlying mechanism. We found that ectopic expression of miR-4443 inhibited PTC cell migration, invasion, ATP production, and aerobic glycolysis, while inhibition of miR-4443 had the opposite effect. miR-4443 directly targeted TRIM14 and reduced both TRIM14 mRNA and protein levels. Silencing TRIM14 significantly reversed miR-4443 inhibition-induced PTC cell migration, invasion, ATP production, aerobic glycolysis, and phosphorylation of the transcription factor STAT3. These findings suggest that miR-4443 is a tumor suppressor in PTC and inhibits metastasis and energy metabolism via the suppression of TRIM14 signaling.

Abstract
OBJECTIVES The role of lncRNAs in gallbladder cancer (GBC) remains poorly understood. In this study, we explored the function of functional intergenic repeating RNA element (FIRRE) in GBC. MATERIALS AND METHODS Whole transcriptome resequencing was performed in three pairs of GBC tissues and adjacent non-tumor tissues. lncRNA FIRRE expression was verified by real-time PCR. The function of FIRRE in GBC was evaluated by experiments in vitro and in vivo. The mechanism of FIRRE was investigated via fluorescent in situ hybridization, RNA pull-down, dual luciferase reporter assays, and RNA immunoprecipitation. RESULTS FIRRE level was dramatically increased in GBC tissues compared to that in the adjacent non-tumor tissues. High expression of FIRRE was closely related to clinical stage and poor prognosis in GBC patients. Moreover, FIRRE remarkably enhanced proliferation and migration, and inhibited apoptosis of GBC cells. Mechanistically, FIRRE modulated YOD1 expression by sponging miR-520a-3p, thus contributing to the development of GBC. CONCLUSION Our data revealed that FIRRE might act as a novel mediator in GBC progression by sponging miR-520a-3p and regulating YOD1. FIRRE might be regarded as a potential diagnostic marker or target for GBC treatment.

Abstract
Background Accumulating evidence shows that lncRNAs are widely involved cellular processes of various tumors. The aim of this study was to explore the potential role and molecular mechanism of lncRNA SNHG16 in nasopharyngeal carcinoma (NPC). Methods SNHG16, miR-520a-3p, and MAPK1 levels were measured by RT-qPCR assay. CCK-8, colony formation, transwell, and flow cytometry assays were adopted to analyze the proliferation, migration, invasion, and apoptosis of NPC cell lines (SUNE1 and 5–8F). Murine xenograft model was used to investigate tumor growth and metastasis in vivo. Immunohistochemical staining was employed to evaluate the levels of Bcl-2, cleaved caspase-3, Bax, and Ki-67. Dual-luciferase reporter assays were conducted to analyze the binding ability between miR-520a-3p and SNHG16 or MAPK1. Results SNHG16 was overexpressed in NPC tissues and cells. High SNHG16 expression indicated a poor prognosis. SNHG16 knockdown could cause significant inhibition on cell proliferation and metastasis, induce cell apoptosis in NPC cells, and repressed tumor growth and metastasis in vivo. Additionally, SNHG16 could directly bind to miR-520a-3p, thus positively regulating MAPK1 expression. Moreover, functional analysis indicated that miR-520a-3p exerted a tumor-suppressing role in NPC progression. Rescue assays demonstrated that MAPK1 upregulation could abrogate the inhibitory effects on NPC cell proliferation and metastasis, as well as the promoting effects on NPC cell apoptosis caused by SNHG16 knockdown. In conclusion, SNHG16 contributed to the proliferation and metastasis of NPC cells by modulating the miR-520a-3p/MAPK1 axis. Conclusion These results suggest that SNHG16 acts as an oncogene in the progression of NPC via modulating the miR-520a-3p/MAPK1 axis.

Abstract
In recent years, FGD5 antisense RNA 1 (FGD5-AS1) was confirmed to be the long non-coding RNAs (lncRNAs) that could accelerate the development of multiple cancers. Nevertheless, specific biological functions and latent mechanism of FGD5-AS1 were not yet clear in pancreatic cancer (PC). This research was aimed to search the functions of FGD5-AS1 on the PC progression. The expression of FGD5-AS1 in PC cells was tested by using RT-qPCR assay. Colony formation assay, EdU assay, flow cytometry assay and transwell assay as well as western blot were adopted to test the cell abilities of proliferation, apoptosis and migration, separately. Furthermore, RIP experiment and pull down assay were applied for validating the correlation FGD5-AS1, miR-520a-3p and KIAA1522. As a result, the abnormal high expression of FGD5-AS1 was observed in PC cells. And cell proliferative and migratory abilities could be restrained via FGD5-AS1 depletion. Moreover, FGD5-AS1 was proven to combine with miR-520a-3p directly. It was also confirmed that KIAA1522 could be targeted by miR-520a-3p. Rescue assay results indicated that overexpressed KIAA1522 could reverse the repressive function of silencing FGD5-AS1 on PC progression. Taken together, FGD5-AS1 accelerated cell proliferation and migration via sponging miR-520a-3p and upregulating KIAA1522.

Abstract
Atherosclerosis (AS), a kind of chronic inflammatory blood vessel disease, is a main cause of cardiovascular disease, which is a leading cause of mortality around the world. Accumulation of macrophages induced by inflammation contributes to AS development. It has been indicated that microRNAs (miRNAs) are involved in the process of AS. However, the pathway and gene miRNAs targeting are poorly understood. Here we reported that miR-520a-3p was increased in mice with AS and silencing of miR-520a-3p attenuated AS process. Furthermore, inhibition of miR-520a-3p increased the expression of α-SMA and collagen. In addition, miR-520a-3p silencing inhibited the expression of M1 macrophage polarization markers and pro-inflammatory genes and promoted the M2 macrophage polarization. What’s more, forced expression of miR-520a-3p diminished IL4/IL13 induced macrophage autophagy via targeting UVRAG. Collectively, our study reveals the role of miR-520a-3p in macrophage polarization and suggests the potential of miRNA as a novel treatment target of AS.

Abstract
Metastasis accounts for the vast majority of deaths in breast cancer, and novel and effective treatments to inhibit cancer metastasis remain urgently developed. The expression level of heat shock protein 90 (HSP90) in invasive breast cancer tissue is higher than in adjacent non-cancerous tissue. In the present study, we investigated the inhibitory effect of penisuloxazin A (PNSA), a novel C- terminal inhibitor of HSP90, on metastasis of breast cancer cells and related mechanism in vitro. We found that PNSA obviously affected adhesion, migration, and invasion of triple-negative breast cancer (TNBC) MDA-MB-231 cells and Trastuzumab-resistant JIMT-1 cells. Furthermore, PNSA was capable of reversing epithelial-mesenchymal transformation (EMT) of MDA-MB-231 cells with change of cell morphology. PNSA increases E-cadherin expression followed by decreasing amounts of N-cadherin, vimentin, and matrix metalloproteinases9 (MMP9) and proteolytic activity of matrix metalloproteinases2 (MMP2) and MMP9. Comparatively, the N-terminal inhibitor of HSP90 17-allyl-17-demethoxygeldanamycin (17-AAG) had no effect on EMT of MDA-MB-231 cells. PNSA was uncovered to reduce the stability of epidermal growth factor receptor (EGFR) and fibroblast growth factor receptor (FGFR) proteins and thereby inhibiting their downstream signaling transductions by inhibition of HSP90. In addition, PNSA reduced the expression of programmed cell death-ligand 1 (PD-L1) to promote natural killer (NK) cells to kill breast cancer cells with a dose far less than that of cytotoxicity to NK cell itself, implying the potential of PNSA to enhance immune surveillance against metastasis in vivo. All these results indicate that PNSA is a promising anti-metastasis agent worthy of being studied in the future.

Abstract
BACKGROUND Osteosarcoma is a common malignant tumor in adolescents with a low 5-year survival rate. Dexmedetomidine (DEX) has been widely used for surgery of osteosarcoma patients. MiR-520a-3p and YOD1 expression was abnormal in osteosarcoma cells. However, whether DEX affects osteosarcoma progression via miR-520a-3p-YOD1 interactome needs to be explored. METHODS We detected osteosarcoma cells biological behavior by CCK-8 assay, BrdU assay, cell adhesion assay, and apoptosis assay, respectively. The miR-520a-3p and YOD1 levels was explored in osteosarcoma cell lines by RT-qPCR or western blotting assay. RESULTS In this study, we found that DEX treating osteosarcoma cells inhibited cell viability, proliferation and adhesion, while it promoted cell apoptosis. Moreover, miR-520a-3p targeting to YOD1 also functionally repressed cell malignancy in osteosarcoma cells. Notably, DEX treatment could inhibit YOD1 expression via upregulating miR-520a-3p, thereby suppressing cell malignancy in osteosarcoma. CONCLUSIONS Our study first revealed that DEX inhibited malignancy of osteosarcoma cells via miR-520a-3p/YOD1 axis.

Abstract
Downregulation of microRNA-520a-3p (miR-520a-3p) has been demonstrated in several cancers, and miR-520a-3p has been shown to inhibit tumor progression, indicating its potential role as a tumor suppressor. In this study, we found that miR-520a-3p was also downregulated in epithelial ovarian cancer (EOC) tissues and cell lines. Functional assays showed that ectopic expression of miR-520a-3p suppressed EOC cell proliferation, invasion, and epithelial-mesenchymal transition (EMT) and induced cell cycle arrest in vitro. Similarly, overexpression of miR-520a-3p inhibited tumor growth and metastasis in vivo. Mechanistically, suppressor of variegation 39H1 (SUV39H1) was identified as a novel target of miR-520a-3p through biomedical databases and dual-luciferase reporter assay. Subsequently, SUV39H1 was observed to be negatively regulated by miR-520a-3p at the mRNA and protein levels, and inversely correlated with miR-520a-3p expression in EOC tissues. Furthermore, overexpression of SUV39H1 reversed the suppressive effects of miR-520a-3p in EOC cells. Collectively, these results suggest that the miR-520a-3p/SUV39H1 axis may contribute to EOC cell proliferation and metastasis, revealing miR-520a-3p as a potential therapeutic target for the treatment of EOC.

Abstract
Simple Summary The most common form of endocrine cancer - papillary thyroid carcinoma, has an increasing incidence. Although this disease usually has an indolent behavior, there are cases when it can evolve more aggressively. It has been known for some time that it is possible to use microRNAs for the diagnosis, prognosis and even treatment monitoring of papillary thyroid cancer. The purpose of this study is to summarize the latest information provided by publications regarding the involvement of microRNAs in papillary thyroid cancer, underling the new clinical perspectives offered by these publications. Abstract The involvement of micro-ribonucleic acid (microRNAs) in metabolic pathways such as regulation, signal transduction, cell maintenance, and differentiation make them possible biomarkers and therapeutic targets. The purpose of this review is to summarize the information published in the last two and a half years about the involvement of microRNAs in papillary thyroid carcinoma (PTC). Another goal is to understand the perspective offered by the new findings. Main microRNA features such as origin, regulation, targeted genes, and metabolic pathways will be presented in this paper. We interrogated the PubMed database using several keywords: “microRNA” + “thyroid” + “papillary” + “carcinoma”. After applying search filters and inclusion criteria, a selection of 137 articles published between January 2018–June 2020 was made. Data regarding microRNA, metabolic pathways, gene/protein, and study utility were selected and included in the table and later discussed regarding the matter at hand. We found that most microRNAs regularly expressed in the normal thyroid gland are downregulated in PTC, indicating an important tumor-suppressor action by those microRNAs. Moreover, we showed that one gene can be targeted by several microRNAs and have nominally described these interactions. We have revealed which microRNAs can target several genes at once.

Abstract
Background Papillary thyroid cancer (PTC) is a kind of thyroid cancer. Previous studies showed that insulin‐like growth factor‐1 (IGF1) plays an important role in tumorigenesis, development, invasion, and metastasis. However, the function of IGF1 in PTC progression remains unclear. Methods Seventy‐three pairs of PTC tissue specimens and adjacent normal specimens form and normal cell line and PTC cell lines were collected in this study. The immunohistochemistry (IHC) assay was performed to test the expression of IGF1. The RNA isolation and quantitative real‐time PCR assays (qRT‐PCR assays) and Western blot analysis were used to test mRNA and protein expression. Cell proliferation assay, EdU assay, flow cytometry assay, wound healing assay, and Transwell invasion assay were performed to test cell proliferation, invasion, and apoptosis. Results We found that the expression of IGF1 in PTC tissue samples was higher than that in adjacent normal specimens and was significantly associated with tumor size, TNM staging, and lymph node metastasis. Furthermore, IGF1 treatment significantly increased cell viability in a dose‐dependent manner. EdU assay also demonstrated the effect of IGF1 on the proliferation of BCPAP and TPC1 cells. Moreover, IGF1 treatment effectively increased the invasive capacity of BCPAP and TPC1 cells. More importantly, IGF1 treatment could significantly enhance the phosphorylation of STAT3 in BCPAP and TPC1 cells. Moreover, cryptotanshinone (Cryp) treatment reversed the effect of IGF1 treatment on cell viability and invasion of BCPAP and TPC1 cells. Conclusion Collectively, IGF1 promotes proliferation and invasion of PTC progression through the STAT3 signaling pathway.

Wang D, Xing N, Yang T, Liu J, Zhao H, He J, Ai Y, Yang J. Exosomal lncRNA H19 promotes the progression of hepatocellular carcinoma treated with Propofol via miR-520a-3p/LIMK1 axis. Cancer Med 2020; 9:7218-7230. [PMID: 32767662 PMCID: PMC7541143 DOI: 10.1002/cam4.3313] [Citation(s) in RCA: 48] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Revised: 05/21/2020] [Accepted: 05/31/2020] [Indexed: 12/29/2022] Open
Abstract
Background Hepatocellular carcinoma (HCC) is one of the leading causes of cancer‐related deaths globally. Herein, we explored the underlying mechanism by which Propofol inhibited the development of HCC. Methods 3‐(4,5‐Dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide (MTT) assay was carried out to detect the viability and proliferation. Quantitative real‐time polymerase chain reaction (qRT‐PCR) and Western blot were performed to detect the expression of long noncoding RNA (lncRNA) H19, microRNA‐520a‐3p (miR‐520a‐3p), LIM domain kinase 1 (LIMK1), metastasis‐associated markers (Snail, Twist, Vimentin and E‐cadherin) and exosome markers (CD9 and CD81). Transmission electron microscopy (TEM) was used to observe the morphology and structure of exosomes. The apoptosis and metastasis were measured by flow cytometry and transwell assays. StarBase software was utilized to predict the targets of H19 and miR‐520a‐3p. Dual‐luciferase reporter assay was performed to confirm the interaction between miR‐520a‐3p and H19 or LIMK1. Nude mice bearing tumors were used to validate the role of exosomal H19. RESULTS The high expression of exosomal H19 accelerated the proliferation and motility while hampering the apoptosis of HCC cells. MiR‐520a‐3p could bind with H19. Exosomal H19 exacerbated HCC through sponging miR‐520a‐3p. The 3’ untranslated region (3’UTR) of LIMK1 could bind to miR‐520a‐3p. MiR‐520a‐3p mimic transfection reversed the inhibitory effect of high expression of exosomal LIMK1 on the apoptosis of HCC cells and the promoting effects on the proliferation and metastasis of HCC cells. The mRNA and protein levels of LIMK1 were regulated by H19/miR‐520a‐3p signaling. The high level of exosomal H19 promoted the growth of HCC tumors in vivo. Conclusion Circulating H19 promoted the proliferation, migration and invasion and inhibited the apoptosis of HCC cells treated with Propofol through upregulating LIMK1 via sponging miR‐520a‐3p.

Abstract
Abnormal expression of neuropilin and tolloid‐like 1 (NETO1) has been detected in some human carcinomas. However, the expression of NETO1 and the underlying mechanism in epithelial ovarian cancer (EOC) remain unknown. In this study, we found that a higher NETO1 expression in EOC tissue samples compared to normal ovarian tissue samples was significantly correlated with worse overall survival. Additionally, Cox regression analysis suggested that NETO 1 was independently associated with overall survival. NETO1 overexpression enhanced the EOC cells’ migration and invasion capability in vitro via regulation of actin cytoskeleton. Mechanistically, silencing NETO1 reduced the expression of β‐tubulin, F‐actin and KIF2A. In conclusion, our results demonstrated the critical role of NETO1 in EOC invasion, and therapies aimed at inhibiting its expression or activity might significantly control EOC growth, invasion and metastatic dissemination.

Abstract
Triclosan (TCS) is a potent antibacterial and antifungal compound that is extensively used in various daily products. TCS is also considered as an underlying endocrine disruptor and has anti-androgenic effects. In our previous work, we found that TCS suppressed testicular steroidogenesis via the miR-6321/JNK/Nur77 cascade, but roles of the abnormal expression of miR-142-5p and P450c17 in this molecular event were still unknown. Therefore, to verify the hypothesis that miR-142-5p and P450c17 might significantly function in other manner in testosterone decline after TCS exposure, Sprague-Dawley rats and the rat Leydig cell line were used in this study. Results showed that after TCS exposure, testicular histomorphology was abnormally changed and testosterone level was declined. Overexpressed miR-142-5p by TCS directly targeted the JAK1/STAT1 pathway. Bidirectional Co-IP assays and the use of STAT1 activator demonstrated that STAT1 could interact with and regulate Sp1. The activity, mRNA level, and protein expression of DNMT1 and DNMT3β were all decreased after TCS treatment. Sp1 silencing, ChIP, and qPCR assays showed that Sp1 regulated DNMT1 expressions by directly binding to the promoter region of DNMT1. Though the DNA methylation status of the DAX1 promoter was not affected, TCS induced the transcription and translation of DAX1 by DNMT1, in turn leading to the inhibition of steroidogenic P450c17. Taken together, TCS-induced miR-142-5p inhibits P450c17 by the JAK1/STAT1 pathway and downstream Sp1/DNMT1/DAX1 cascade, finally facilitating the decrease in testosterone levels.

Abstract
Programmed cell death-ligand 1 (PD-L1) is a glycoprotein that is expressed on the cell surface of both hematopoietic and nonhematopoietic cells. PD-L1 play a role in the immune tolerance and protect self-tissues from immune system attack. Dysfunction of this molecule has been highlighted in the pathogenesis of tumors, autoimmunity, and infectious disorders. MicroRNAs (miRNAs) are endogenous molecules that are classified as small non-coding RNA with approximately 20-22 nucleotides (nt) length. The function of miRNAs is based on complementary interactions with target mRNA via matching completely or incompletely. The result of this function is decay of the target mRNA or preventing mRNA translation. In the past decades, several miRNAs have been discovered which play an important role in the regulation of PD-L1 in various malignancies. In this review, we discuss the effect of miRNAs on PD-L1 expression and consider the effect of miRNAs on the synthetic pathway of PD-L1, especially during cancers.

Abstract
The Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathway is involved in cell immunity, division and death, as well as in tumor formation. The expression of key genes in the JAK-STAT signaling pathway in different types of cancer serves different roles. However, few reports are available on the prognostic value of the genes of the JAK-STAT signaling pathway in skin cutaneous melanoma (SKCM). The potential prognostic value of gene expression in the JAK-STAT signaling pathway in patients with SKCM was analyzed in the present study using data obtained from The Cancer Genome Atlas. To predict the potential functions and mechanisms of these genes in SKCM, gene set enrichment analysis (GSEA) and bioinformatics analysis were performed. A nomogram model including gene expression level and high risk factors was used to predict the risk level of prognostic. High expression levels of STAT1, STAT3, STAT4 and STAT5B, and low expression levels of STAT6 were associated with favorable prognosis [adjusted P<0.001; hazard ratio (HR), 0.595; 95% confidence interval (CI), 0.455–0.778; adjusted P=0.018; HR, 0.725; 95% CI, 0.555–0.947; adjusted P<0.001; HR, 0.590; 95% CI, 0.450–0.773; adjusted P=0.007; HR, 0.690; 95% CI, 0.526–0.940; and adjusted P=0.026; HR, 0.737, 95% CI, 0.563–0.964, respectively]. GSEA results demonstrated that these genes were involved in cell differentiation, invasion, adhesion, migration, cycle, colony formation and mitogen-activated protein kinase signaling. The combination of genes with favorable prognosis had a better effect on the overall survival (univariate survival analysis, P<0.05). The results of the present study suggest that STAT1, STAT3, STAT4, STAT5B and STAT6 gene expression may be used as a potential prognostic biomarker of SKCM, and the combined outcomes may exhibit a stronger interaction and higher survival time for SKCM.

Abstract
Background: The long noncoding RNA (lncRNA) functions as a regulator of initiation, progression, and metastasis of thyroid carcinomas. lncRNA OTUD6B antisense RNA 1 (OTUD6B-AS1) is a tumor-suppressive noncoding RNA in clear cell renal cell carcinoma. The role of OTUD6B-AS1 in thyroid carcinomas has not been reported yet. We aim to investigate the expression and biological functions of OTUD6B-AS1 in thyroid carcinomas. Methods: The expression level of OTUD6B-AS1 was measured in 60 paired human thyroid carcinoma tissues and corresponding adjacent normal thyroid tissues. The correlations between the OTUD6B-AS1 expression levels and clinicopathological features were evaluated using the Mann-Whitney test. The effects of OTUD6B-AS1 on thyroid carcinoma cells were determined via the MTT and transwell assays. The potential targets of OTUD6B-AS1 were screened using the online programs OncomiR and StarBase 3.0, and the LncBase Predicted v.2. Luciferase reporter assay was used to confirm the interactions between OTUD6B-AS1 and its potential targets. Results: OTUD6B-AS1 was downregulated in thyroid carcinoma tissue samples. The expression of OTUD6B-AS1 correlated with tumor size, clinical stage, and lymphatic metastasis of thyroid carcinoma. Overexpression of OTUD6B-AS1 significantly decreased the viability, migration, and invasion of thyroid carcinoma cells. Online programs predicted miR-183-5p and miR-21 as potential targets of OTUD6B-AS1. Luciferase reporter assays showed miR-183-5p and miR-21 bound to OTUD6B-AS1. Moreover, overexpression of miR-183-5p and miR-21 compromised the inhibitory effects of OTUD6B-AS1 on viability, migration, and invasion of thyroid carcinoma cells. Conclusions: Taken together, our findings present in vitro evidence of lncRNA OTUD6B-AS1 as a tumor suppressor in thyroid carcinomas. OTUD6B-AS1 inhibits viability, migration, and invasion of thyroid carcinoma by targeting miR-183-5p and miR-21.

Abstract
Purpose Various microRNAs are involved in the development of gastric cancer (GC). This study investigated the role and mechanism of miR-520a-3p in GC. Method Quantitative real-time fluorescence PCR (qRT-PCR) was applied to measure the expression level of miR-520a-3p in GC tissues and cell lines. The chi-squared test was employed to evaluate the relationship between the expression level of miR-520a-30p and clinical traits. The cell count kit-8 assay was used to detect the effect of miR-520a-3p on GC cell proliferation, while its effect on glycolysis was determined using the glucose assumption, lactate, and ATP production assay. The effect of miR-520a-3p on tumor growth in vivo was examined using a xenograft model. The relationship between miR-520a-30p and AKT1/mTOR/HIF1α pathway in normoxia and hypoxia was investigated using bioinformatics analysis, dual-luciferase reporter assay, qRT-PCR and Western blotting. Results The expression of miR-520a-3p was decreased in GC tissues and cell lines. The expression level of miR-520a-3p was negatively associated with various malignant biological properties in patients. Overexpression/inhibition of miR-520a-3p decreased/promoted cell proliferation and glycolysis in vitro. Overexpression of miR-520a-3p inhibited tumor growth in vivo. AKT1 is the functional target of MiR-520a-3p, which was decreased in miR-520a-3p-overexpressing cells. In addition, overexpression of miR-520a-3p decreased the protein level of AKT1, mTOR, HIF1α, and target genes of HIF1α such as Glut1 and VEGF. Restoration of the expression of AKT1 can decrease the inhibitory effect of miR-520a-3p on the AKT1/mTOR/HIF1α pathway, as well as cell proliferation and glycolysis. Furthermore, the level of miR-520a-3p was decreased, while that of AKT1 was increased under hypoxia. Notably, inhibition of HIF1α or overexpression of miR-520a-3p suppressed these effects. Conclusion Our study provided the first evidence for the existence of HIF1α/miR-520a-3p/AKT1/mTOR feedback, which promotes the proliferation and glycolysis of GC cells, highlighting a potential novel target for treatment.

Abstract
The Metastatic progression of solid tumors, such as thyroid cancer is a complex process which involves various factors. Current understanding on the role of epithelial-mesenchymal transition (EMT) in thyroid carcinomas suggests that EMT is implicated in the progression from follicular thyroid cancer (FTC) and papillary thyroid cancer (PTC) to poorly differentiated thyroid carcinoma (PDTC) and anaplastic thyroid cancer (ATC). According to the literature, the initiation of the EMT program in thyroid epithelial cells elevates the number of stem cells, which contribute to recurrent and metastatic diseases. The EMT process is orchestrated by a complex network of transcription factors, growth factors, signaling cascades, epigenetic modulations, and the tumor milieu. These factors have been shown to be dysregulated in thyroid carcinomas. Therefore, molecular interferences restoring the expression of tumor suppressors, or thwarting overexpressed oncogenes is a hopeful therapeutic method to improve the treatment of progressive diseases. In this review, we summarize the recent findings on EMT in thyroid cancer focusing on the main role-players and regulators of this process in thyroid tumors.

Abstract
Background miR520a-3p has previously had its antitumorigenic role in various types of cancers revealed, and been predicted as a posttranscriptional regulator of the NFκB-subunit RELA gene. Thus, miR520a-3p could function in carcinogenesis through suppressing RELA. Methods Expression of miR520a-3p and RELA mRNA was quantified in glioma and normal tissue, and the correlation between them was analyzed statistically. Also, receiver-operating characteristic (ROC)–curve analysis was performed. Effects of miR520a-3p on cell viability, colony formation, migration, and invasion wereexplored in vitro. Whether RELA was a direct target of miR520a-3p or not was analyzed. Finally, restoration of RELA on the effect of miR520a-3p overexpression on proliferation of glioblastoma cells was detected. Results Data showed that miR520a-3p expression was aberrantly downregulated and associated with malignance in glioma tissue. Areas under ROC curves of miR520a-3p and RELA mRNA expression were 0.9483 and 0.5967, respectively. Also, miR520a-3p expression was statistically correlated with RELA mRNA level in grade III–IV glioma tissue. Transfection of miR520a-3p mimic significantly increased miR520a-3p expression, and resulted in significant suppression of proliferation, migration, and invasion of glioblastoma cells in vitro. miR520a-3p overexpression resulted in statistical downregulation of RELA, both in mRNA and protein levels. RELA was direct target of miR520a-3p. In addition, restoration of RELA significantly weakened the inhibitory effect of miR520a-3p overexpression on viability and EdU-labeled glioblastoma cells. Conclusion These findings suggest that miR520a-3p should be helpful in auxiliary glioma diagnosis and can attenuate the proliferation and metastasis of glioblastoma through suppressing RELA, and thus could be an attractive therapeutic target to eliminate glioblastoma.

Abstract
Thyroid cancer (TC) is a prevalent endocrine malignant cancer whose pathogenic mechanism remains unclear. The aim of the study was to investigate the roles of long non‐coding RNA (lncRNA) NR2F1‐AS1/miRNA‐338‐3P/CCND1 axis in TC progression. Differentially expressed lncRNAs and mRNAs in TC tissues were screened out and visualized by R program. Relative expression of NR2F1‐AS1, miRNA‐338‐3p and cyclin D1 (CCND1) was determined by quantitative real time polymerase chain reaction. In addition, Western blot analysis was adopted for evaluation of protein expression of CCND1. Targeted relationships between NR2F1‐AS1 and miRNA‐338‐3p, as well as miRNA‐338‐3p and CCND1 were predicted using bioinformatics analysis and validated by dual‐luciferase reporter gene assay. Besides, tumour xenograft assay was adopted for verification of the role of NR2F1‐AS1 in TC in vivo. NR2F1‐AS1 and CCND1 were overexpressed, whereas miRNA‐338‐3p was down‐regulated in TC tissues and cell lines. Down‐regulation of NR2F1‐AS1 and CCND1 suppressed proliferation and migration of TC cells yet greatly enhanced cell apoptotic rate. Silence of NR2F1‐AS1 significantly suppressed TC tumorigenesis in vivo. NR2F1‐AS1 sponged miRNA‐338‐3p to up‐regulate CCND1 expression to promote TC progression. Our study demonstrated that up‐regulation of NR2F1‐AS1 accelerated TC progression through regulating miRNA‐338‐3P/CCND1 axis.

Abstract
Epithelial-mesenchymal transition (EMT) symbolizes the predominant program of advanced-stage cancer, it is critical in cancer progression, metastasis, and chemotherapy resistance. In this study, the metastatic properties of nasopharyngeal carcinoma (NPC) cells were evaluated by morphological examination, wound healing assay, migration and invasion assay. Western blotting and qRT-PCR were used to ascertain the expression of markers which were associated with EMT. The effects of miR-205-5p on invasion, migration, EMT and proliferation of NPC cells were evaluated and the molecular mechanisms of their interaction were explored. In this study, we manifested firstly that the expression of miR-205-5p in cisplatin-resistant NPC cell line HNE1/DDP was obviously up-regulated than that in its parental cell line HNE1. Then we analyzed the specific role of miR-205-5p through functional assays by transfecting specific mimics and inhibitors. The results indicated that low expression of miR-205-5p restrained EMT progression of HNE1/DDP cells. Further studies on the mechanism of miR-205-5p manifested that PTEN was a downstream candidate gene of miR-205-5p, down-regulated PTEN expression could counteract the effect of miR-205-5p inhibitors, and the regulation of EMT by miR-205-5p on HNE1/DDP cells depended on the PI3K/AKT signaling pathway. Overall, our results indicated that miR-205-5p was targeting PTEN to regulate EMT through the PI3K/AKT pathway. This study will supply a new treatment target for advanced NPC.

Guo H, Zhang L. MicroRNA-30a suppresses papillary thyroid cancer cell proliferation, migration and invasion by directly targeting E2F7. Exp Ther Med 2019; 18:209-215. [PMID: 31258655 PMCID: PMC6566087 DOI: 10.3892/etm.2019.7532] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2018] [Accepted: 02/05/2019] [Indexed: 01/23/2023] Open
Abstract
microRNA (miRNA/miR)-30a, a tumor-associated miRNA, has been implicated in the tumorigenesis and progression of different types of human cancer. Thyroid cancer is a common endocrine malignancy, of which papillary thyroid cancer (PTC) accounts for ~80-90% of all TC. However, the effect of miR-30a in PTC is yet to be fully elucidated. The TPC-1 human PTC cell line, as well as the normal human thyroid cell line (HT-ori3), were utilized in the current study. The PTC cell line was transfected with a miR-30a mimic. Subsequently, reverse transcription-quantitative polymerase chain reaction was performed to detect the expression of miR-30a and E2F transcription factor 7 (E2F7). Cell proliferation was assessed via a MTT assay and transwell migration and invasion assays were performed to detect the migration and invasion of PTC cells. A dual-luciferase reporter assay was also utilized to clarify the association between miR-30a and E2F7. The results of the current study revealed that miR-30a was significantly downregulated in TPC-1 cells compared with HT-ori3 cells and that the expression of E2F7 was significantly upregulated in PTC cells. The upregulation of miR-30a also inhibited the proliferation, migration and invasion of PTC cells. Furthermore, the luciferase assay revealed that miR-30a binds to the 3'-UTR of E2F7. Additionally, the overexpression of miR-30a decreased E2F7 levels in TPC-1 cells. These results indicate that miR-30a functions as a tumor suppressor in PTC by direct targeting E2F7 and that miR-30a may be a novel therapeutic target for patients with PTC.

Oncol Rep 2019; 41:3270-3280. [PMID: 31002347 PMCID: PMC6488982 DOI: 10.3892/or.2019.7123] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Accepted: 04/03/2019] [Indexed: 12/21/2022] Open
Abstract
Leucine-rich-alpha-2-glycoprotein 1 (LRG-1) has been reported to be associated with multiple malignancies. However, its participation in thyroid carcinoma progression remains unclear. In the present study, the biological function and underlying molecular mechanisms of LRG-1 in thyroid carcinoma were investigated. It was found that LRG-1 was overexpressed in thyroid carcinoma tissues, and high LRG-1 expression predicted poor patient survival and late tumor stage. As shown in the mouse xenograft study, knockdown of LRG-1 significantly attenuated thyroid cancer growth in vivo. Based on wound healing, Transwell, proliferation and apoptosis assays, it was found that the knockdown of LRG-1, using shLRG-1, inhibited cell migration and invasion, but did not affect proliferation and apoptosis in thyroid cancer cells. Furthermore, LRG-1 also induced epithelial-mesenchymal transition (EMT) in thyroid carcinoma cells. Western blot analysis revealed that this tumor-promoting bioactivity of LRG-1 was attributed to its selective activation of MAPK/p38 signaling. All of these findings indicate that LRG-1 plays a deleterious role in the progression of thyroid carcinoma. LRG-1 may serve as a promising biomarker for predicting prognosis in thyroid carcinoma patients, and LRG-1-based therapy may be developed into a novel strategy for the treatment of thyroid carcinoma.
