[PMID: 37666286 DOI: 10.1016/j.cellsig.2023.110881] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 08/30/2023] [Accepted: 09/01/2023] [Indexed: 09/06/2023]
Abstract
The metastasis a major hallmark of tumors that its significant is not only related to the basic research, but clinical investigations have revealed that majority of cancer deaths are due to the metastasis. The metastasis of tumor cells is significantly increased due to EMT mechanism and therefore, inhibition of EMT can reduce biological behaviors of tumor cells and improve the survival rate of patients. One of the gaps related to cancer metastasis is lack of specific focus on the EMT regulation in certain types of tumor cells. The gastric and bladder cancers are considered as two main reasons of death among patients in clinical level. Herein, the role of EMT in regulation of their progression is evaluated with a focus on the function of miRNAs. The inhibition/induction of EMT in these cancers and their ability in modulation of EMT-related factors including ZEB1/2 proteins, TGF-β, Snail and cadherin proteins are discussed. Moreover, lncRNAs and circRNAs in crosstalk of miRNA/EMT regulation in these tumors are discussed and final impact on cancer metastasis and response of tumor cells to the chemotherapy is evaluated. Moreover, the impact of miRNAs transferred by exosomes in regulation of EMT in these cancers are discussed.

Abstract
Dysregulation of microRNAs (miRNAs or miRs) is implicated in the development of gastric cancer (GC), which is possibly related to their roles in targeting tumor-suppressive or tumor-promoting genes. Herein, the current study was intended to ascertain the function of miR-488 and its modulatory mechanism in GC. Initially, human GC cells were assayed for their in vitro malignancy after miRNA gain- or loss-of-function and RNA interference or overexpression. Also, tumorigenesis and liver metastasis were evaluated in nude mouse models. Results demonstrated that miR-488 elevation suppressed GC (MKN-45 and OCUM-1) cell proliferation, migration, and invasiveness in vitro and reduced their tumorigenesis and liver metastasis in vivo. The luciferase assay identified that miR-488 bound to HULC and inhibited its expression. Furthermore, HULC could enhance EZH2-H3K27me3 enrichment at the p53 promoter region and epigenetically repress the p53 expression based on the data from RIP- and ChIP-qPCR assay. Additionally, HULC was validated to enhance GC growth and metastasis in vitro and in vivo. Overall, HULC re-expression elicited by miR-488 inhibition can enhance EZH2-H3K27me3 enrichment in the p53 promoter and repress the p53 expression, thus promoting the growth and metastasis of GC.

Abstract
Psoriasis is a persistent, inflammatory, autoimmune skin disorder which can be elicited by genetic and environmental factors. Several microRNAs (miRNAs) that are abnormally expressed in psoriasis have emerged as an interesting candidate in psoriasis pathogenesis. However, the expression profile and function of miRNA-559, and its direct target metadherin (MTDH), in psoriasis need to be further illuminated. This study intended to assess miRNA-559 and MTDH levels in skin and sera of psoriatic patients and to investigate their clinical significance in an attempt for developing novel distinct tools for early diagnosis of psoriasis. Moreover, this study aimed at exploring participation of miRNA-559 in regulating MTDH/PTEN/AKT pathway in psoriasis. Expression levels of miRNA-559, AKT, FOXO1 and PTEN were measured by real-time qRT-PCR, whereas MTDH and p27 levels were assessed by ELISA in lesional, non-lesional tissues and serum of 20 psoriatic patients and 20 matching controls. Correlation study was conducted between different parameters. The diagnostic performance of miRNA-559 and MTDH in psoriasis was estimated by receiver operating characteristic (ROC) curve analysis. Expression of miRNA-559 in psoriatic patients was significantly downregulated in both lesional tissues and serum as compared to controls. Conversely, MTDH protein level showed significant increase in both tissues and serum of psoriatic patients and was inversely correlated with miRNA-559 level. Meanwhile, levels of PTEN, AKT and FOXO1 were dramatically changed in psoriatic patients compared to controls. Furthermore, serum miRNA-559 and MTDH displayed comparable diagnostic accuracy in discriminating psoriatic patients from controls. Yet, miRNA-559 demonstrated superior diagnostic performance than MTDH in psoriasis diagnosis. Together, the current findings provide the first suggestion of a new mechanism by which downregulation of miRNA-559 might induce proliferation in psoriasis through modulating PTEN/AKT/FOXO1 pathway by positive regulation of MTDH. Thus, miRNA-559 and MTDH might be proposed as promising diagnostic biomarkers of psoriasis.

Front Physiol 2022; 13:929094. [PMID: 35936896 PMCID: PMC9351827 DOI: 10.3389/fphys.2022.929094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 06/27/2022] [Indexed: 11/24/2022] Open
Abstract
MicroRNAs, as one of the post-transcriptional regulation of genes, play an important role in the development process, cell differentiation and immune defense. The sea cucumber Apostichopus japonicus is an important cold-water species, known for its excellent nutritional and economic value, which usually encounters heat stress that affects its growth and leads to significant economic losses. However, there are few studies about the effect of miRNAs on heat stress in sea cucumbers. In this study, high-throughput sequencing was used to analyze miRNA expression in the body wall of sea cucumber between the control group (CS) and the heat stress group (HS). A total of 403 known miRNAs and 75 novel miRNAs were identified, of which 13 miRNAs were identified as significantly differentially expressed miRNAs (DEMs) in response to heat stress. A total of 16,563 target genes of DEMs were predicted, and 101 inversely correlated target genes that were potentially regulated by miRNAs in response to heat stress of sea cucumbers were obtained. Based on these results, miRNA-mRNA regulatory networks were constructed. The expression results of high-throughput sequencing were validated in nine DEMs and four differentially expressed genes (DEGs) by quantitative real-time polymerase chain reaction (RT-qPCR). Moreover, pathway enrichment of target genes suggested that several important regulatory pathways may play an important role in the heat stress process of sea cucumber, including ubiquitin-mediated proteolysis, notch single pathway and endocytosis. These results will provide basic data for future studies in miRNA regulation and molecular adaptive mechanisms of sea cucumbers under heat stress.

Abstract
Colorectal cancer (CRC) is one of the most common cancers in the world. The incidence rate of cancer is high. The overall response to traditional treatment methods such as surgery, radiotherapy, and chemotherapy is not very satisfactory. Therefore, finding new therapeutic targets is very important for improving CRC treatment. In recent reports, the role of circRNAs in regulating colorectal angiogenesis has been gradually revealed. CircRNAs can indirectly act on angiogenesis pathways and regulate the expression of growth factors such as vascular endothelial growth factor (VEGF). CircRNAs are endogenous noncoding RNAs formed by pre-mRNAs through exon circular splicing. The covalent closed-loop structure makes these RNAs highly conserved and stable. CircRNAs have been found in human plasma, serum, urine, and other body fluids. Their highly conserved characteristics play important roles in many biological activities. CircRNAs can participate in the progression of many diseases by sponging miRNAs, interacting with proteins, and regulating transcription. Angiogenesis can provide nutrients and oxygen for tumour proliferation and metastasis. Angiogenesis is an important sign of the formation of the tumour microenvironment. Here, we will summarize the role of the latest circRNAs in the mechanism of angiogenesis in CRC and provide potential therapeutic targets for clinical treatment.

Abstract
OBJECTIVE Cervical cancer remains a leading cause of gynecological cancer-related death. In this study, we aimed to investigate the expression pattern of miR-599 and its prognostic significance in cervical cancer. MATERIALS AND METHODS The RT-qPCR analysis was used to detect the expression levels of miR-599 in cervical cancer tissues and cell lines. The association between miR-599 expression and clinical characteristics of cervical cancer patients was analyzed using the χ2 test. The Kaplan-Meier analysis and multivariate Cox proportional hazards model were used to explore the prognostic significance of miR-599. Then, CCK-8 assays, transwell migration, and invasion assays were used to assess the effects of miR-599 on tumor cell proliferation, migration, and invasion of cervical cancer cells, respectively. RESULTS miR-599 expression was significantly downregulated in cervical cancer tissues and cells compared with non-cancerous tissues and HaCaT cells, respectively. Statistical analysis revealed that miR-599 expression was associated with lymph node metastasis and FIGO stage. The miR-599 expression was an independent prognostic factor for overall survival. Functionally, overexpression of miR-599 suppressed cell proliferation, migration, and invasion of cervical cancer cells, while downregulation of miR-599 had opposite effects. CONCLUSION miR-599 acts as a tumor suppressor in cervical cancer that inhibiting cell proliferation, migration, and invasion of cervical cancer cells, suggesting that miR-599 may be a potential prognostic biomarker and novel targeted strategy for cervical cancer.

Abstract
BACKGROUND Progression of Barrett esophagus (BE) to esophageal adenocarcinoma occurs among a minority of BE patients. To date, BE behavior cannot be predicted on the basis of histologic features. AIMS We compared BE samples that did not develop dysplasia or carcinoma upon follow-up of ≥ 7 years (BE nonprogressed [BEN]) with BE samples that developed carcinoma upon follow-up of 3 to 4 years (BE progressed [BEP]). METHODS The NanoString nCounter miRNA assay was used to profile 24 biopsy samples of BE, including 13 BENs and 11 BEPs. Fifteen samples were randomly selected for miRNA prediction model training; nine were randomly selected for miRNA validation. RESULTS Unpaired t tests with Welch's correction were performed on 800 measured miRNAs to identify the most differentially expressed miRNAs for cases of BEN and BEP. The top 12 miRNAs (P < .003) were selected for principal component analyses: miR-1278, miR-1301, miR-1304-5p, miR-517b-3p, miR-584-5p, miR-599, miR-103a-3p, miR-1197, miR-1256, miR-509-3-5p, miR-544b, miR-802. The 12-miRNA signature was first self-validated on the training dataset, resulting in 7 out of the 7 BEP samples being classified as BEP (100% sensitivity) and 7 out of the 8 BEN samples being classified as BEN (87.5% specificity). Upon validation, 4 out of the 4 BEP samples were classified as BEP (100% sensitivity) and 4 out of the 5 BEN samples were classified as BEN (80% specificity). Twenty-four samples were evaluated, and 22 cases were correctly classified. Overall accuracy was 91.67%. CONCLUSION Using miRNA profiling, we have identified a 12-miRNA signature able to reliably differentiate cases of BEN from BEP.

Abstract
Androgen receptor (AR) is an androgen-activated transcription factor of the nuclear receptor superfamily. AR plays a role in the development and progression of prostate cancer (PCa). However, the exact role of AR in PCa metastasis remains unclear. In the present study, we aimed to elucidate the function of AR in PCa. We found that eukaryotic translation initiation factor (EIF) 5A2, an elongation factor that induces epithelial-to-mesenchymal transition (EMT) in PCa cells, was significantly upregulated after 5α-dihydrotestosterone (DHT) stimulation and downregulated after anti‐androgen bicalutamide treatment in PCa cells with high AR expression, but not in cells with low AR expression. Moreover, eIF5A2 knockdown could eliminate DHT-induced invasion and migration of AR-positive PCa cells. DHT treatment decreased epithelial expression of E‐cadherin and β-catenin but increased the expression of the mesenchymal marker proteins Vimentin and N-cadherin. DHT therefore induced EMT, and knockdown of eIF5A2 inhibited DHT-induced EMT. Moreover, in vivo study, Luciferase signals from the lungs of the eIF5A2 plasmid group indicated higher metastasis ability, and the eIF5A2 siRNA group had lower metastasis ability. Our results suggest that AR positively regulates eIF5A2 expression in androgen-dependent cells, and stimulation of AR expression and signaling in prostate tumors promotes PCa metastasis by EMT induction and upregulation of eIF5A2.

Abstract
N1, N12-Diacetylspermine (DiAcSpm) has been reported to be upregulated in the urine of cancer patients. Mass spectrometry has shown elevated DiAcSpm expressions in colorectal cancer (CRC) tissues. However, the diagnostic application of DiAcSpm is not available due to a lack of diagnostic grade antibodies. Also, its biological roles in CRC cells remain unexplored. In the present study, we developed an antibody that directly detected DiAcSpm expression in paraffin-embedded tissues. We also characterized its biological characteristics and underlying mechanisms. Polyclonal antibodies were generated by immunizing animals with a synthetic product of DiAcSpm. Antibody DAS AB016 showed strong sensitivity against DiAcSpm in CRC tissues. Immunohistochemistry results showed that DiAcSpm expression was significantly elevated in CRC tissues. High levels of DiAcSpm correlated with the clinical stage and Ki67 index. DiAcSpm treatment increased levels of proliferation, cell cycle progression, and cyclin D1 and cyclin E proteins in CRC cell lines, SW480 and Caco-2. DiAcSpm also upregulated ATP production in these two cell lines. RNA-sequencing showed that DiAcSpm downregulated miR-559, which was confirmed using RT-qPCR. The luciferase reporter assay, western blotting, and RT-qPCR showed that cystathionine β-synthase (CBS) was the target of miR-559. miR-559 inhibited, while CBS accelerated, CRC proliferation. In addition, CBS siRNA knockdown blocked the biological effects of DiAcSpm on CRC cells. In conclusion, DiAcSpm was found to be increased in CRC tissues using a newly developed antibody. DiAcSpm accelerated CRC proliferation by regulating the miR-559/CBS axis.

Circular RNA (circRNA) and their associated competing endogenous RNA (ceRNA) network play critical roles in the pathogenesis of glioma. However, the alteration of the circRNA-miRNA-mRNA regulatory network and its correlation with glioma therapy haven't been systematically analyzed. Methods With GEO, GEPIA2, circBank, CSCD, CircInteractome, mirWalk 2.0, and mirDIP 4.1, we constructed a circRNA-miRNA-mRNA network in glioma. LASSO regression and multivariate Cox regression analysis established a hub mRNA signature to assess the prognosis. GSVA was used to estimate the immune infiltration level. Potential anti-glioma drugs were forecasted using the cMap database and evaluated with GSEA using GEO data. Results A ceRNA network of seven circRNAs (hsa_circ_0030788/0034182/0000227/ 0018086/0000229/0036592/0002765), 15 miRNAs(hsa-miR-1200/1205/1248/ 1303/3925-5p/5693/581/586/599/607/640/647/6867-5p/767-3p/935), and 46 mRNAs (including 11 hub genes of ARHGAP11A, DRP2, HNRNPA3, IGFBP5, IP6K2, KLF10, KPNA4, NRP2, PAIP1, RCN1, and SEMA5A) was constructed. Functional enrichment showed they influenced majority of the hallmarks of tumors. Eleven hub genes were proven to be decent prognostic signatures for glioma in both TCGA and CGGA datasets. Forty-six LASSO regression significant genes were closely related to immune infiltration. Finally, five compounds (fulvestrant, tanespimycin, mifepristone, tretinoin, and harman) were predicted as potential treatments for glioma. Among them, mifepristone and tretinoin were proven to inhibit the cell cycle and DNA repair in glioma. Conclusion This study highlights the potential pathogenesis of the circRNA-miRNA-mRNA regulatory network and identifies novel therapeutic options for glioma.

MiR-599 targeting TOP2A inhibits the malignancy of bladder cancer cells. Biochem Biophys Res Commun 2021; 570:154-161. [PMID: 34284141 DOI: 10.1016/j.bbrc.2021.06.069] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 06/16/2021] [Accepted: 06/19/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND Recent research suggests that many miRNAs influence the development of bladder cancer (BC). However, the function of the miR-599/TOP2A axis in BC cells is still unclear. Our aim was to verify the effect of the miR-599/TOP2A axis on BC progression. METHODS The expression of TOP2A and miR-599 in BC tissues and cells was detected using RT-qPCR. Luciferase assays, RIP assays, and RNA pull-down assays were performed to determine the interaction between miR-599 and TOP2A. CCK-8, flow cytometry-based apoptosis, wound healing, and Transwell assays were utilized to determine the proliferation, migration, invasion and apoptosis of BC cells. RESULTS MiR-599 was significantly downregulated in the BC, and miR-599 overexpression impeded the malignancy of BC cells by regulating proliferation, migration, invasion and apoptosis. TOP2A proved to a downstream target of miR-599 could enhance the tumorigenesis phenotype of BC cells. The experimental results also indicated that miR-599 reversed the oncogenic effects induced by TOP2A. CONCLUSION Our study revealed that miR-599 represses BC tumorigenesis by inhibiting TOP2A.

Abstract
BACKGROUND VSMC proliferation and migration pathways play important roles in plaque formation in the vessel stenosis and re-stenosis processes. The microRNAs affect the expression of many genes that regulate these cellular processes. The aim of this study was to investigate the effects of miR-181b, miR-204, and miR-599 on the gene and protein expression levels of hematopoietic cell kinase (HCK) in VSMCs. METHODS miR-181b, miR-204 were predicted for the suppression of HCK in the chemokine signaling pathway using bioinformatics tools. Then, the VSMCs were transfected by PEI-containing microRNAs. The HCK gene and protein expression levels were evaluated using RT-qPCR and Western blotting techniques, respectively. Moreover, the cellular proliferation and migration were evaluated by MTT and scratch assay methods. RESULTS The miR-181b and miR-204 decreased significantly the HCK gene and (total and phosphorylated) protein expression levels. Also, the miR-599 did not show any significant effects on the HCK gene and protein levels. The data also showed that miR-181b, miR-204, and miR-599 prevent significantly the proliferation and migration of VSMCs. CONCLUSION The downregulation of HCK by miR-181b and miR-204 suppressed the VSMC proliferation and migration.

Abstract
ABSTRACT Long noncoding RNAs could participate in the development of atherosclerosis (AS). However, the underlying mechanism by which long noncoding RNA H19 is implicated in AS remains largely unknown. In this study, we investigated the function of H19 on cell proliferation, migration, and invasion in oxidized low-density lipoprotein (ox-LDL)-treated human aortic vascular smooth muscle cells (HA-VSMCs), and on hyperlipidemia response in high-fat diet (HFD)-treated ApoE-/- mice. Moreover, we explored the target interaction among H19, microRNA (miR)-599, and pappalysin 1 (PAPPA). Our results showed that H19 expression was elevated in serum samples of patients with AS and ox-LDL-treated HA-VSMC. H19 silence mitigated ox-LDL-induced proliferation, migration, and invasion of HA-VSMCs. H19 acted as a sponge for miR-599, and miR-599 knockdown reversed the suppressive effect of H19 silence on proliferation, migration, and invasion of HA-VSMCs. PAPPA was a target of miR-599 and attenuated the inhibitive role of miR-599 in HA-VSMC processes. H19 knockdown repressed PAPPA expression by increasing miR-599. Moreover, H19 interference alleviated hyperlipidemia response in HFD-treated ApoE-/- mice. Collectively, knockdown of H19 inhibited proliferation, migration, and invasion of ox-LDL-treated HA-VSMCs and hyperlipidemia response in HFD-treated ApoE-/- mice by regulating miR-599/PAPPA axis, indicating H19 might act as a potential target for the treatment of AS.

Abstract
Background Medulloblastoma (MB) is the most common malignant brain tumor during childhood. Circular RNA (circSKA3) was identified to function as an oncogene in MB. However, the mechanism of circSKA3 in MB remains unclear. Methods The levels of circSKA3, microRNA-383-5p (miR-383-5p), and forkhead box M1 (FOXM1) in MB tissues were measured by quantitative real-time polymerase chain reaction (qRT-PCR). The cell viability and apoptotic rate were assessed via 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay and flow cytometry, respectively. The protein levels of B-cell lymphoma 2 (Bcl-2), C-Caspase3, and FOXM1 were detected via Western blot assay. Cell cycle was detected by flow cytometry. The migration and invasion abilities were monitored by Transwell assay. The dual-luciferase reporter assay was constructed to verify the interactions between miR-383-5p and circSKA3 or FOXM1. The mice model experiment was carried out to validate the effects of circSKA3 in vivo. Results The levels of circSKA3 and FOXM1 were significantly elevated, while the level of miR-383-5p was notably declined in MB tissues. CircSKA3 was validated to sponge miR-383-5p, and FOXM1 was a candidate target of miR-383-5p. CircSKA3 silencing impeded cell proliferation, migration, and invasion while promoted apoptosis by targeting miR-383-5p in vitro and retarded xenograft tumor growth in vivo. miR-383-5p suppressed cell proliferation, migration, and invasion but promoted apoptosis in MB cells by regulating FOXM1. CircSKA3 depletion decreased FOXM1 expression via miR-383-5p in MB cells. Conclusion CircSKA3 augmented MB progression partly through miR-383-5p/FOXM1 axis.

Abstract
Cancer is the leading cause of death worldwide. The absence of obvious symptoms and insufficiently sensitive biomarkers in early stages of carcinoma limits early diagnosis. Cancer therapy agents and targeted therapy have been used extensively against tissues or organs of specific cancers. However, the intrinsic and/or acquired resistance to the agents or targeted drugs as well as the serious toxic side effects of the drugs would limit their use. Therefore, identifying biomarkers involved in tumorigenesis and progression represents a challenge for cancer diagnosis and therapeutic strategy development. The eukaryotic translation factor 5A (eIF5A), originally identified as an initiation factor, was later shown to promote translation elongation of iterated proline sequences. There are two eIF5A isoforms (eIF5A1 and eIF5A2). eIF5A2 protein consists of 153 residues, and shares 84% amino acid identity with eIF5A1. However, the biological functions of these two isoforms may be significantly different. Recently, it was demonstrated that eIF5Ais widely involved in the pathogenesis of a number of diseases, including cancers. In particular, eIF5A plays an important role in regulating tumor growth, invasion, metastasis and tumor microenvironment. It was also shown to serve as a potential biomarker and target for the diagnosis and treatment of cancers. The present review briefly discusses the latest findings of eIF5A in the pathogenesis of certain malignant cancers and evolving clinical applications.

Abstract
The effective non-invasive diagnosis and prognosis are critical for cancer treatment. The plasma cell-free DNA (cfDNA) provides a good material for cancer liquid biopsy and its worth in this field is increasingly explored. Here we describe a new pipeline for effectively finding new cfDNA-based biomarkers for cancers by combining SALP-seq and machine learning. Using the pipeline, 30 cfDNA samples from 26 esophageal cancer (ESCA) patients and 4 healthy people were analyzed as an example. As a result, 103 epigenetic markers (including 54 genome-wide and 49 promoter markers) and 37 genetic markers were identified for this cancer. These markers provide new biomarkers for ESCA diagnosis, prognosis and therapy. Importantly, these markers, especially epigenetic markers, not only shed important new insights on the regulatory mechanisms of this cancer, but also could be used to classify the cfDNA samples. We therefore developed a new pipeline for effectively finding new cfDNA-based biomarkers for cancers by combining SALP-seq and machine learning. In this study, we also discovered new clinical worth of cfDNA distinct from other reported characters.

Abstract
Background Currently, multiple circular RNAs (circRNAs) have been verified to act as essential regulators in the progression of gastric cancer (GC). We aimed to investigate the role of circ_0008035 in GC progression. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) was utilized to measure the expression of circ_0008035 and miR-599. 3-(4,5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) assay was employed to evaluate cell proliferation and ferroptosis. Western blot assay was performed to measure the levels of cyclin D1, proliferating cell nuclear antigen (PCNA) and eukaryotic initiation factor 4A1 (EIF4A1). Flow cytometry analysis was conducted to assess cell apoptosis. The iron accumulation, lipid peroxidation and mitochondrial membrane potential were examined by relevant kits. Dual-luciferase reporter assay was conducted to determine the targeting relationship between miR-599 and circ_0008035 or EIF4A1. A murine xenograft model was established to investigate the function of circ_0008035 in vivo. Results Circ_0008035 was up-regulated in GC tissues and cells. Silencing of circ_0008035 repressed cell proliferation and induced cell apoptosis and ferroptosis in GC cells. Circ_0008035 acted as a sponge of miR-599. The effects of circ_0008035 knockdown on GC cell proliferation, apoptosis and ferroptosis were abolished by miR-599 inhibition. EIF4A1 was confirmed to be a target gene of miR-599. Circ_0008035 knockdown inhibited EIF4A1 expression by targeting miR-599. Moreover, the suppressive role of circ_0008035 deficiency in GC progression could be restored by EIF4A1. Additionally, circ-0008035 knockdown hampered tumorigenesis in vivo. Conclusion Circ_0008035 promoted GC cell growth and repressed apoptosis and ferroptosis by up-regulating EIF4A1 through sponging miR-599.

Abstract
The eukaryotic translation initiation factor 5A1 (eIF5A1) and its homolog eIF5A2 are the only two human proteins containing the unique post-translational modification-hypusination, which is essential for the function of these two proteins. eIF5A1 was initially identified as a translation initiation factor by promoting the first peptide bond formation of protein during translation; however, recent results suggest that eIF5A1 also functions as a translation elongation factor. It has been shown that eIF5A1 is implicated in certain human diseases, including diabetes, several human cancer types, viral infections and diseases of neural system. Meanwhile, eIF5A2 is overexpressed in many cancers, and plays an important role in the development and progression of cancers. As multiple roles of these two factors were observed among these studies, therefore, it remains unclear whether they act as oncogene or tumor suppressor. In this review, the recent literature of eIF5As and their roles in human diseases, especially in human cancers, will be discussed.

Abstract
Background Previous studies have shown that P73 antisense RNA 1T (non-protein coding), also known as TP73-AS1, is a long non-coding RNA (lncRNA) and involved in the development of medulloblastoma. However, the regulatory mechanism of lncRNA TP73-AS1 in medulloblastoma was still unclear, the present study was aimed to investigate the detailed functions and the mechanism of TP73-AS1 in regulation of medulloblastoma. Materials and methods The levels of TP73-AS1, miR-494-3p, and Eukaryotic initiation factor 5A2 (EIF5A2) were determined using quantitative real-time PCR (qRT-PCR), in situ hybridization (ISH), or Immunohistochemistry (IHC). The function of TP73-AS1 in proliferation, apoptosis, migration, and invasion of medulloblastoma cells was evaluated using cell counting Kit-8 (CCK-8), flow cytometry, and transwell assay, respectively. The protein levels were determined by Western blot. Bioinformatics analysis and dual-luciferase reporter assay, RNA immunoprecipitation (RIP) and pull-down assay were used to search and confirm the target gene of TP73-AS1 and miR-494-3p. The effect of TP73-AS1 knockdown in vivo was detected by animal experiment. Results The levels of TP73-AS1 and EIF5A2 were up-regulated, while miR-494-3p expression was down-regulated in medulloblastoma tissues and cells, ELF5A2 was a direct target of miR-494-3p, and miR-494-3p bound to TP73-AS1. The knockdown of TP73-AS1 inhibited cell proliferation, invasion, migration, and promoted apoptosis of medulloblastoma cells, while the miR-494-3p inhibitor abolished the effects of TP73-AS1 knockdown on medulloblastoma cells. Conclusion TP73-AS1 positively regulated EIF5A2 expression by sponging miR-494-3p. These findings suggested that TP73-AS1 served as an oncogene and promoted the progression of medulloblastoma.

[PMID: 31788073 PMCID: PMC6865640 DOI: 10.3892/ol.2019.10984] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Accepted: 08/06/2019] [Indexed: 12/13/2022] Open
Abstract
Drug resistance is a significant obstacle when treating triple-negative breast cancer (TNBC). Several studies have demonstrated that microRNAs (miRNAs) have essential roles in regulating drug resistance in different types of cancer. miR-33a-5p has previously been reported to be a tumor suppressor in several types of cancer. However, its role in breast cancer remains unknown. The present study aimed to investigate the role of miR-33a-5p in the chemoresistance of TNBC and uncover its potential molecular mechanisms. Cell Counting Kit-8 assay was used to examine cell proliferation, reverse transcription-quantitative PCR analysis was used to examine miR-33a levels, and western blotting and immunofluorescence assays were used to examine the expression of epithelial-mesenchymal transition (EMT)-associated proteins and of eukaryotic translation initiation factor 5A2 (eIF5A2). The results indicated that miR-33a-5p expression was lower in TNBC cells compared with non-TNBC cells. miR-33a-5p overexpression significantly improved the doxorubicin (Dox) sensitivity of TNBC cells, but not that of non-TNBC cells. It was then observed that Dox treatment inhibited miR-33a-5p expression and induced EMT in TNBC cells, by increasing the expression levels of vimentin, while decreasing the expression levels of E-cadherin. Furthermore, it was revealed that forced expression of miR-33a-5p attenuated Dox-induced EMT. eIF5A2 was identified as a potential target of miR-33a-5p, and miR-33a-5p overexpression inhibited the expression of eIF5A2. eIF5A2 inhibition, via its inhibitor GC7, sensitized TNBC cells to Dox and reversed Dox-induced EMT. Overall, the present study demonstrated that miR-33a-5p enhanced the sensitivity of TNBC cells to Dox, by suppressing eIF5A2 expression and reversing Dox-induced EMT, providing a potential therapeutic target for treating drug-resistant TNBC.

Abstract
Purpose Thermo-chemotherapy (TCT) is a new approach for the treatment of cancer that combines chemotherapy with thermotherapy. In the present study, we investigated the relationship between eukaryotic translation initiation factor 5A2 (EIF5A2) and TCT sensitivity in gastric cancer (GC) to further illuminate the molecular mechanism underlying the effect of TCT on GC. Methods A TCT cell model was constructed, and EIF5A2 was silenced or overexpressed by infection with a lentivirus expressing either EIF5A2 or EIF5A2 shRNA. Then, RT-qPCR, Western blotting, and immunohistochemistry assays were performed to evaluate the changes in the expression levels of EIF5A2, c-myc, vimentin, and E-cadherin. Cell proliferation and xenograft assays were conducted to evaluate the effect on cell proliferation. Finally, wound-healing and Transwell invasion assays were performed to evaluate the effects on migration and invasion. Results TCT reduced EIF5A2 expression at both the mRNA and protein levels. It also inhibited cell proliferation, migration, and invasion, downregulated the expression of c-myc and vimentin, and increased the expression of E-cadherin in both MKN28 and MKN45 cells. Silencing of EIF5A2 enhanced the above effects of TCT on MKN28 and MKN45 cells, while overexpression of EIF5A2 had the opposite effects. In addition, EIF5A2 overexpression weakened the inhibitory effect of TCT on tumor growth in vivo as well as the effects on c-myc, vimentin, and E-cadherin. Conclusion TCT inhibits GC cell proliferation and metastasis by suppressing EIF5A2 expression. Our results provide new insights into our understanding of the molecular mechanism underlying the effects of TCT in GC.

Abstract
Anaplastic thyroid cancer (ATC) has a mean survival time of 6 months and accounts for 1-2% of all thyroid tumors. Understanding the underlying molecular mechanisms of carcinogenesis and progression in ATC would contribute to the identification of novel therapeutic targets. A previous study revealed that microRNA (miR)-599 was associated with tumor initiation and development in certain types of cancer. However, the specific functions and mechanisms of miR-599 in ATC are poorly understood. The objective of the present study was to identify its expression, function and molecular mechanism in ATC. The expression levels of miR-599 in 10 pairs of surgical specimens and human ATC cell lines were examined by reverse transcription-quantitative polymerase chain reaction. Function assays illustrated that miR-599 overexpression not only suppressed KAT-18 cell viability, proliferation and metastasis in vitro and decreased tumor growth in the tumor xenograft model but also induced cell apoptosis. Furthermore, T-cell intracellular antigen (TIA1), a tumor suppressor, was confirmed as a direct target of miR-599. It was demonstrated that TIA1 silencing rescued the inhibitory effect of migration and invasion induced by the overexpression of miR-599 in KAT-18 cells. In conclusion, the present study revealed that miR-599 inhibited ATC cell growth and metastasis via activation of TIA1. Therefore miR-599 may be a novel molecular therapeutic target for ATC.

Abstract
Gastric cancer is one of the leading causes of cancer-related deaths worldwide, and mortality remains high, especially in East Asia. At present, the main method to diagnose gastric cancer is pathological biopsy. At the time of diagnosis, most patients have been diagnosed with advanced cancer and metastasis. The treatment of gastric cancer patients is mainly radical surgical resection and chemoradiotherapy, while patients with metastatic tumor have great challenges to radical surgery and are prone to drug resistance. Metastasis is an important factor affecting tumor development. In addition, evidence accumulated in the literature indicates that non-coding RNA plays a key role in tumor metastasis. This article reviews the role of ncRNAs in gastric cancer metastasis and discusses the regulatory mechanism in the development and treatment of gastric cancer.

Abstract
Eukaryotic initiation factor 5A2 (eIF5A2), as one of the two isoforms in the family, is reported to be a novel oncogenic protein that is involved in multiple aspects of many types of human cancer. Overexpression or gene amplification of EIF5A2 has been demonstrated in many cancers. Accumulated evidence shows that eIF5A2 initiates tumor formation, enhances cancer cell growth, increases cancer cell metastasis, and promotes treatment resistance through multiple means, including inducing epithelial–mesenchymal transition, cytoskeletal rearrangement, angiogenesis, and metabolic reprogramming. Expression of eIF5A2 in cancer correlates with poor survival, advanced disease stage, as well as metastasis, suggesting that eIF5A2 function is crucial for tumor development and maintenance but not for normal tissue homeostasis. All these studies suggest that eIF5A2 is a useful biomarker in the prediction of cancer prognosis and serves as an anticancer molecular target. This review focuses on the expression, subcellular localization, post-translational modifications, and regulatory networks of eIF5A2, as well as its biochemical functions and evolving clinical applications in cancer, especially in human digestive system neoplasms.

Abstract
Serotonin and its receptors have been shown to play critical regulatory roles in cancer biology. Nevertheless, the contributions of 5-hydroxytryptamine 1D (5-HT1D), an indispensable member of the serotonergic system, to hepatocellular carcinoma (HCC) remain unknown. The present study demonstrated that the 5-HT1D expression level was significantly up-regulated in HCC tissues and cell lines. The 5-HT1D expression level was closely correlated with unfavorable clinicopathological characteristics. Survival analyses show that elevated 5-HT1D expression level predicts poor overall survival and high recurrence probability in HCC patients. Functional studies revealed that 5-HT1D significantly promoted HCC proliferation, epithelial-mesenchymal transition, and metastasis in vitro and in vivo. Mechanistically, 5-HT1D could stabilize PIK3R1 by inhibiting its ubiquitin-mediated degradation. The interaction between 5-HT1D and phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1) enhanced the expression of FoxO6 through the PI3K/Akt signaling pathway; FoxO6 could also be directly transcriptionally activated by 5-HT1D in an Akt-independent manner. MicroRNA-599 was found to be an upstream suppressive modulator of 5-HT1D. Additionally, 5-HT1D could attenuate tryptophan hydroxylase 1 expression through the PI3K/Akt/cut-like homeobox 1 axis in HCC. Conclusion: Herein, we uncovered the potent oncogenic effect of 5-HT1D on HCC by interacting with PIK3R1 to activate the PI3K/Akt/FoxO6 pathway, and provided a potential therapeutic target for HCC.

Abstract
Osteosarcoma (OS) is the most frequent bone malignancy in human. Growing evidence suggests that circular RNAs (circRNAs) play a significant role in regulating tumorigenesis and progression. Previously, circ_0001721 was identified upregulated in OS tissues screened by circRNA microarrays. In the current study, circ_0001721 expression in OS tissue samples and cells were measured by qRT-PCR. Its clinical value was also explored. For the part of functional assays, CCK-8, clone-forming, flow cytometric, Transwell, xenograft assays were performed. Dual luciferase reporter assays were used to examine the mechanism of circ_0001721. We found that circ_0001721 was enhanced in OS tissue samples and cell lines and the overexpression of circ_0001721 is closely related to clinical severity. In addition, circ_0001721 may be used as a prognostic indicator for OS patients. What's more, loss-of-function and gain-of-function assays demonstrated circ_0001721 facilitates cell progression in OS. Circ_0001721 could sponge miR-569 and miR-599. The oncogenic properties of circ_0001721 is partly attributed to its repression on miR-569 and miR-599. Collectively, the present data reveal the participation of circ_0001721 in tumorigenesis of OS cells, and may indicate a novel therapeutic target.

Abstract
The sea cucumber Apostichopus japonicus is a valuable species in China. The extreme high temperature in the summer often results in high mortality. MicroRNAs (miRNAs) play important post-transcriptional regulatory roles in gene expression and can influence heat shock response (HSR) greatly. In this study, we determined the expression profiles of miRNAs under heat stress (HS) in A. japonicus by using high-throughput sequencing technique. Among the differential expression miRNAs, we highlighted 41 differentially expressed miRNAs, many of which were involved in immunity process and disease regulation. Gene ontology and pathway analyses of putative target genes were also carried out. Cell-substrate adherens junction and cell-substrate junction were significantly enriched in GO analysis. Moreover, we made a correlation analysis between remarkable miRNAs and the differentially expressed genes (DEGs) in sea cucumbers under HS. We identified 17 key miRNA-target pairs potentially regulated HSR of sea cucumbers. These results will provide new insights about miRNAs regulation and molecular adaptive mechanisms in sea cucumbers under HS.

Abstract
A large body of evidence has indicated that microRNAs (miRNAs/miRs) have essential roles in the development and progression of cervical cancer. Thus, miRNAs with dysregulated expression are potential biomarkers for cervical cancer diagnosis and prognosis. In the present study, expression levels of miR‑485 were detected in cervical cancer tissues and cell lines. The effects of miR‑485 overexpression on the proliferation and invasion of cervical cancer cells were determined with Cell Counting kit‑8 and Transwell invasion assays. The mechanisms underlying the action of miR‑485 in cervical cancer were investigated using bioinformatics analysis, a luciferase reporter assay, reverse transcription‑quantitative polymerase chain reaction and western blot analysis. In addition, the association between miR‑485 and metastasis associated in colon cancer‑1 (MACC1) in cervical cancer tissues was examined. The present study demonstrated that miR‑485 expression was significantly downregulated in cervical cancer tissues and cell lines. Reduced miR‑485 expression in patients with cervical cancer was correlated with International Federation of Gynecology and Obstetrics stage and lymph node metastasis. Furthermore, restored expression of miR‑485 significantly reduced cervical cancer cell proliferation and invasion. MACC1 was identified as a direct target gene of miR‑485 in cervical cancer. MACC1 expression was significantly upregulated in cervical cancer specimens and was inversely correlated with miR‑485 expression. Additionally, the restored expression of MACC1 eliminated the suppressive effects of miR‑485 overexpression on the proliferation and invasion of cervical cancer cells. Notably, the upregulation of miR‑485 suppressed the MET proto‑oncogene, receptor tyrosine kinase (Met)/RAC‑α serine/threonine‑protein kinase (AKT) signaling pathway. These results demonstrated that miR‑485 may perform its tumor suppressive function in cervical cancer by directly targeting MACC1 and inhibiting the Met/AKT signaling pathway. Therefore, the miR‑485/MACC1 axis may be a novel and effective therapeutic target in cervical cancer.

Dysregulation of microRNAs (miRNAs) is associated with the occurrence and development of clear cell renal cell carcinoma (ccRCC) through their participation in a number of critical biological processes. Therefore, an in‑depth investigation into miRNAs and their biological roles within ccRCC may provide useful insights and lead to the identification of novel therapeutic methods for patients with ccRCC. miRNA‑599 (miR‑599) serves critical roles in different types of human cancer. However, the expression pattern, biological function and molecular mechanism of miR‑599 in ccRCC remain unknown. The present study aimed to detect the expression level of miR‑599 in ccRCC, examine its effect on ccRCC progression and further explore the possible underlying mechanisms. It was observed that miR‑599 was significantly underexpressed in ccRCC tissues and cell lines compared with the control. Functional assays revealed that restored expression of miR‑599 restricted the proliferation and invasion of ccRCC cells. Bioinformatics analysis, luciferase reporter assay, reverse transcription‑quantitative polymerase chain reaction and western blot analysis demonstrated that high‑mobility group AT‑hook 2 (HMGA2) was a direct target of miR‑599 in ccRCC. HMGA2 knockdown simulated the suppressive effects caused by miR‑599 overexpression in ccRCC. Recovered HMGA2 expression partially rescued the miR‑599‑mediated inhibition of ccRCC proliferation and invasion. These results suggest that miR‑599 may serve tumour suppressive roles in ccRCC by directly targeting HMGA2, indicating that miR‑599 may have potential as a treatment for patients with ccRCC.
