Huang Z, Li H, Li Q, Chen X, Liu R, Chang X. Matrine suppresses liver cancer progression and the Warburg effect by regulating the circROBO1/miR-130a-5p/ROBO1 axis. J Biochem Mol Toxicol 2023; 37:e23436. [PMID: 37376914 DOI: 10.1002/jbt.23436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 05/15/2023] [Accepted: 06/13/2023] [Indexed: 06/29/2023]
Abstract
Matrine, an effective component extracted from the traditional Chinese herb, Sophora flavescens, has been indicated to exert antitumor activity in different types of cancer. However, the role and precise mechanism of matrine in the progression of liver cancer remains largely unclear. Cell viability, cell proliferation, cell apoptosis, and Warburg effect were estimated by cell counting kit-8 assay, colony formation assay, flow cytometry assay, and glucose uptake and lactate production assay, respectively. The candidate Circular RNAs (circRNAs) were screened by integrating the Gene Expression Omnibus database (GSE155949) analysis with the online program GEO2R. A quantitative real-time polymerase chain reaction was employed to test the expression of circRNA circROBO1, microRNA miR-130a-5p, and roundabout homolog 1 (ROBO1). The interaction of circROBO1/miR-130a-5p/ROBO1 axis was predicted and confirmed by bioinformatics analysis, a dual-luciferase reporter assay, and an RNA pull-down assay. A xenograft mouse model was employed to reveal the role of matrine in vivo. Matrine repressed liver cancer cell viability, proliferation, and Warburg effect, but increased cell apoptosis in vitro. CircROBO1 and ROBO1 were upregulated, but miR-130a-5p was downregulated in liver cancer tissues. Additionally, matrine could reduce the expression of circROBO1 and ROBO1, and increase the expression of miR-130a-5p. Mechanically, overexpression of circROBO1 partly recovered the effect of matrine on liver cancer cell viability, proliferation, apoptosis, and Warburg effect by regulating the miR-130a-5p/ROBO1 axis. Matrine impeded liver cancer development by mediating the circROBO1/miR-130a-5p/ROBO1 axis, which provided a theoretical basis for the application of matrine as an effective anticancer drug for liver cancer.

Abstract
Liver fibrosis is a common outcome of most chronic liver insults/injuries that can develop into an irreversible process of cirrhosis and, eventually, liver cancer. In recent years, there has been significant progress in basic and clinical research on liver cancer, leading to the identification of various signaling pathways involved in tumorigenesis and disease progression. Slit glycoprotein (SLIT)1, SLIT2, and SLIT3 are secreted members of a protein family that accelerate positional interactions between cells and their environment during development. These proteins signal through Roundabout receptor (ROBO) receptors (ROBO1, ROBO2, ROBO3, and ROBO4) to achieve their cellular effects. The SLIT and ROBO signaling pathway acts as a neural targeting factor regulating axon guidance, neuronal migration, and axonal remnants in the nervous system. Recent findings suggest that various tumor cells differ in SLIT/ROBO signaling levels and show varying degrees of expression patterns during tumor angiogenesis, cell invasion, metastasis, and infiltration. Emerging roles of the SLIT and ROBO axon-guidance molecules have been discovered in liver fibrosis and cancer development. Herein, we examined the expression patterns of SLIT and ROBO proteins in normal adult livers and two types of liver cancers: hepatocellular carcinoma and cholangiocarcinoma. This review also summarizes the potential therapeutics of this pathway for anti-fibrosis and anti-cancer drug development.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 312:120022. [PMID: 36028080 DOI: 10.1016/j.envpol.2022.120022] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Revised: 08/17/2022] [Accepted: 08/18/2022] [Indexed: 06/15/2023]
Abstract
Perfluorooctanoic acid (PFOA) could induce developmental toxicities, affecting various organs, including the heart. Although peroxisome-proliferation activated receptor alpha (PPARα) had been identified as a major target of PFOA, PPARα-independent effects are frequently reported. To further elucidate the mechanism of toxicity in PFOA-induced developmental cardiotoxicity, RNA-seq analysis was performed in hatchling chicken hearts developmentally exposed to vehicle or 2 mg/kg (egg weight) PFOA. RT-PCR and western blotting were then performed to confirm the identified potential targets. Furthermore, lentivirus was designed to overexpress and silence identified target miRNA in developing chicken embryo, and the resulting phenotypes were investigated. 21 miRNAs and 1142 mRNAs were identified to be affected by developmental exposure to PFOA in chicken embryo hearts. Among the identified differentially expressed miRNAs, miR-490-5p was confirmed to be significantly affected by PFOA exposure, along with its downstream targets, Synaptosome associated protein 91 (SNAP91) and LY6/PLAUR domain containing 6 (LYPD6), as indicated by RT-PCR and western blotting results. Lentivirus overexpressing miR-490-5p mimicked the phenotype induced by PFOA exposure, while lentivirus silencing miR-490-5p alleviated PFOA-induced changes. Similar patterns were also observed in the expression of downstream target genes, SNAP91 and LYPD6. In summary, miR-490-5p and its downstream genes, SNAP91 and LYPD6 are associated with PFOA-induced developmental cardiotoxicity in chicken embryo, which might help to further elucidate the mechanism of PFOA-induced developmental cardiotoxicity.

Bioinformatic Deconstruction of Differentially Expressed Sequence Tags in Hepatocellular Carcinoma Based on Artificial Neural Network. CONTRAST MEDIA & MOLECULAR IMAGING 2022; 2022:6716324. [PMID: 36299828 PMCID: PMC9576451 DOI: 10.1155/2022/6716324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Revised: 09/05/2022] [Accepted: 09/19/2022] [Indexed: 01/26/2023]
Abstract
Traditional medical imaging methods for diagnosing hepatocellular carcinoma can only provide information for differential diagnosis in terms of morphology and blood supply of the lesion, and the determination of the nature of the lesion still relies on tissue biopsy. Although ultrasound or CT-guided biopsy has become an effective method for the diagnosis of liver cancer in recent years, the puncture has the possibility of tumor irritation, liver tumor rupture, or needle tract metastasis. In this paper, the use of bioinformatics method is to gradually screen potentially high-risk genes associated with HCC recurrence on a genome-wide scale would help to discover the key target molecules. The ANN method was used to establish a gene prediction model that can predict the recurrence and survival of HCC, so as to construct a tool to identify patients at risk of HCC recurrence. It provided a certain therapeutic basis for future clinical work, thereby improving the prognosis of patients with HCC. Using the "survfit" function of the "survival" package in the R language, the log-rank test (the log-rank test was a common method for comparing two survival curves) was performed on all genes with posthoc recurrence of hepatocellular carcinoma as the outcome event. Then, the BLAST tool (Basic Local Alignment Search Tool) was used to search the similarity of each hepatocellular carcinoma database to find out the genes with similar sequences to each hepatocellular carcinoma, so as to determine the function of each differentially expressed sequence tag. This paper found that the AUC of the ANN model was greater than that of the discriminant analysis model (P < 0.05). This paper promoted the development of new therapeutic measures for hepatocellular carcinoma and provided important theoretical guidance for human beings to fight cancer.

Characterization of altered microRNAs related to different phenotypes of polycystic ovarian syndrome (PCOS) in serum, follicular fluid, and cumulus cells. Taiwan J Obstet Gynecol 2022; 61:768-779. [PMID: 36088043 DOI: 10.1016/j.tjog.2022.05.013] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/16/2022] [Indexed: 10/14/2022] Open
Abstract
OBJECTIVE Polycystic ovarian syndrome (PCOS) is a metabolic syndrome in which steroidogenesis, folliculogenesis, and cellular adhesion play crucial roles in its prognosis. These pathways are controlled and regulated by some small non-coding RNAs called microRNAs (miRs). Several miRs have differential expression in PCOS compared to healthy women, and their dysregulation suggests important roles of miRs in PCOS pathophysiology. However, the role of miRs is still unclear, especially in various phenotypes of PCOS. MATERIALS AND METHODS This study was conducted to evaluate the diagnostic potential of miR-212-3p, miR-490-5p, miR-647, and miR-4643 in different subtypes of PCOS. Accordingly, nineteen PCOS patients with different subtypes based on Rotterdam criteria (A: 8, B: not detected in this study, C: 5, and D: 6 patients) and six control age and BMI matched women under ICSI treatment were selected. The relative expression of miRs was then measured in blood serum before hormonal treatment (S1) and before ovum pickup (S2), follicular fluid (FF), and cumulus cells (CC) in all subjects. Also, the expression of miRs predicted target genes (AMH, AR, CYP11A1, CYP17A1, CYP19A1, GDF9, and HSD17B12) were done in the CC of understudy groups. RESULTS In general, the results indicated that PCOS significantly increased the expression of miR-212-3p, miR-490-5p, and miR-4643 in FF and CCs compared to control. Although these miRs tend to increase in serum 1 of the PCOS patients, the differences were insignificant. However, there was a significant reduction in the expression of miR-647 in FF and CCs between PCOS vs. control. In addition, the miRs had significantly different expressions in various phenotypes of PCOS. For example, high levels of miR-647 in S2 and low levels of miR-490 in FF and miR-212 in CC can differentiate phenotype A from the other. Also, upregulation of miR-212 in FF and miR-4643 in S1 and low levels of this miR in FF can specifically differentiate subtype A from D. On the other hand, high levels of miR-4643 in FF and miR-490 in CC and lower titter of miR-647 can distinguish subtype C from the other. On the other hand, high levels of AMH, AR, CYP11, CYP17, and HSD17 in the hyperandrogenic PCOS and upregulation of CYP19A1 in the hypoandrogenic group can validate the role of selected miRs in the prognosis of PCOS. CONCLUSION Characterization of altered microRNAs in serum, FF, and CCs and their targets in CC showed that the miRs might play critical roles in steroidogenesis and folliculogenesis. These miRs may be used for molecular classification of PCOS subtypes and as biomarkers for PCOS diagnosis.

Abstract
Background: This study aimed to screen potential drugs targeting a new prognostic gene signature associated with proliferation in hepatocellular carcinoma (HCC). Methods: CRISPR Library and TCGA datasets were used to explore differentially expressed genes (DEGs) related to the proliferation of HCC cells. Differential gene expression analysis, univariate COX regression analysis, random forest algorithm and multiple combinatorial screening were used to construct a prognostic gene signature. Then the predictive power of the gene signature was validated in the TCGA and ICGC datasets. Furthermore, potential drugs targeting this gene signature were screened. Results: A total of 640 DEGs related to HCC proliferation were identified. Using univariate Cox analysis and random forest algorithm, 10 hub genes were screened. Subsequently, using multiplex combinatorial screening, five hub genes (FARSB, NOP58, CCT4, DHX37 and YARS) were identified. Taking the median risk score as a cutoff value, HCC patients were divided into high- and low-risk groups. Kaplan-Meier analysis performed in the training set showed that the overall survival of the high-risk group was worse than that of the low-risk group (p < 0.001). The ROC curve showed a good predictive efficiency of the risk score (AUC > 0.699). The risk score was related to gene mutation, cancer cell stemness and immune function changes. Prediction of immunotherapy suggetsted the IC50s of immune checkpoint inhibitors including A-443654, ABT-888, AG-014699, ATRA, AUY-922, and AZ-628 in the high-risk group were lower than those in the low-risk group, while the IC50s of AMG-706, A-770041, AICAR, AKT inhibitor VIII, Axitinib, and AZD-0530 in the high-risk group were higher than those in the low-risk group. Drug sensitivity analysis indicated that FARSB was positively correlated with Hydroxyurea, Vorinostat, Nelarabine, and Lomustine, while negatively correlated with JNJ-42756493. DHX37 was positively correlated with Raltitrexed, Cytarabine, Cisplatin, Tiotepa, and Triethylene Melamine. YARS was positively correlated with Axitinib, Fluphenazine and Megestrol acetate. NOP58 was positively correlated with Vorinostat and 6-thioguanine. CCT4 was positively correlated with Nerabine. Conclusion: The five-gene signature associated with proliferation can be used for survival prediction and risk stratification for HCC patients. Potential drugs targeting this gene signature deserve further attention in the treatment of HCC.

Abstract
BACKGROUND miR-152-3p functions as a tumour suppressor in the progression of hepatic tumorigenesis. Herein, we further discussed the prognostic significance and immune infiltration of miR-152-3p and its potential gene target in hepatocellular carcinoma (HCC). METHODS The Cancer Genome Atlas (TCGA), Integrative Molecular Database of Hepatocellular Carcinoma (HCCDB), Human Protein Atlas (HPA) and Kaplan-Meier Plotter databases were used to evaluate miR-152-3p and roundabout guidance receptor 1 (ROBO1) expression, prognosis and immune infiltration. In vitro cell experiments, including cell proliferation and apoptosis, were evaluated using Cell Counting Kit 8 (CCK8) and terminal-deoxynucleotidyl transferase-mediated nick end labelling (TUNEL) assays. RESULTS Up-regulation of ROBO1 functioned as an oncogene associated with poor prognosis, immune cell enrichment and cell proliferation in HCC. ROBO1 was significantly positively correlated with the enrichment of multiple immune cells and their biomarkers. Enrichment of type-2 T-helper (Th2) cells is an unfavourable biomarker of HCC prognosis. GSEA revealed that ROBO1 correlated with apoptosis, mitosis and carcinogenic signalling pathways. Suppression of cell proliferation and the enhancement of cell apoptosis by miR-152-3p mimics were counteracted by overexpression of ROBO1 in HCC cells. CONCLUSION ROBO1 expression is positively correlated with multiple immune checkpoint molecules, suggesting that ROBO1 may be a potential drug target to enhance the potency of immunotherapy. The miR-152-3p/ROBO1 signalling axis contributes to malignant progression and provides a prospective immunotherapeutic target for HCC.

Abstract
Pancreatic cancer with about 5% five-year overall survival rate remains a challenge. Invasion and migration of pancreatic cancer cells are the main factors leading to poor prognosis. MicroRNA-490-5p (miR-490-5p) has anti-cancer effects in a variety of tumors, but its role in pancreatic cancer has not been reported. The mRNA expressions of miR-490-5p, MAGI2 antisense RNA 3 (MAGI2-AS3), Matrix metalloproteinase (MMP)2, MMP9, N-cadherin, and E-cadherin were detected by quantitative real-time PCR, while the protein expressions of these genes except miR-490-5p were measured by Western blot analysis. The cell viability, apoptosis, migration and invasion were detected by cell counting kit-8 (CCK-8), apoptosis and transwell assays. MiR-490-5p was abnormally low-expressed in pancreatic cancer, whose down-regulation generated enhanced effects on viability, migration and invasion in pancreatic cancer cells, as well as MAGI2-AS3 expression. MiR-490-5p mimic exerted the opposite effect on cells, which also down-regulated MMP2, MMP9, and N-cadherin protein expressions, while up-regulating E-cadherin protein expression. MAGI2-AS3, which was the targeted binding site of miR-490-5p, promoted viability, migration and invasion, and inhibited apoptosis of cancer cells. More importantly, miR-490-5p played an anti-cancer role in pancreatic cancer by targeting MAGI2-AS3 and regulating epithelial-mesenchymal transition (EMT), which was partially offset by MAGI2-AS3.

Abstract
Gastric cancer (GC) accounts for a main cause of cancer-related deaths. This study sought for molecular mechanism of miR-490-5p/DTL axis in affecting GC progression, thus bringing new hope for treatment of GC. Expression data of differentially expressed miRNAs and mRNAs in GC tissue from TCGA database were analyzed. MiR-490-5p and DTL mRNA expression levels in GC were evaluated with qRT-PCR. Cell viability was confirmed with CCK-8 method. Cell cycle distribution and apoptosis were analyzed with flow cytometry. Cell migratory and invasive potential was proved with Transwell assay. The targeted relationship between DTL and miR-490-5p was analyzed with dual-luciferase assay. The results indicated a decreased miR-490-5p level in GC cells. MiR-490-5p upregulation hampered proliferation, migration, invasion and promote cell apoptosis. DTL was the target of and inversely associated with miR-490-5p, and it could remarkably induce the carcinogenesis of GC. MiR-490-5p mediated GC cell progression by DTL repression. In conclusion, miR-490-5p and DTL may be valuable in diagnosis and treatment for GC.

Abstract
MicroRNA (miR)-490-3p and miR-490-5p, located on chromosome 7q33, are two independent mature products of miR-490 exerting distinct effects on tumor progression. miR-490-3p and miR-490-5p possess antitumor properties. miR-490-3p dysfunction has been associated with malignancies including colorectal cancer, while the abnormal function of miR-490-5p has been more considerably associated with bladder cancer (for example). At present, there are 30 and 11 target genes of miR-490-3p and miR-490-5p, respectively, that have been experimentally verified, of which the cyclin D1 (CCND1) gene is a common target. Through these target genes, miR-490-3p and miR-490-5p are involved in 7 and 3 signaling pathways, respectively, of which only 2 are shared regulatory signaling pathways. The present review introduces two competing endogenous RNA (ceRNA) regulatory networks centered on miR-490-3p and miR-490-5p. These networks may be important promoters of tumor cell proliferation, invasiveness, metastatic potential and apoptosis. Unlike miR-490-5p, miR-490-3p plays a unique role in promoting cancer. However, both are promising molecular markers for early cancer diagnosis and prognosis. In addition, miR-490-3p was also found to be associated with the chemical resistance of cisplatin and paclitaxel. The present review focuses on the abnormal expression of miR-490-3p and miR-490-5p in different tumor types, and their complex ceRNA regulatory networks. The clinical value of miR-490-3p and miR-490-5p in cancer diagnosis, prognosis and treatment is also clarified, and an explanation for the opposing effects of miR-490-3p in tumor research is provided.

Life Sci 2021; 271:119111. [PMID: 33513398 DOI: 10.1016/j.lfs.2021.119111] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 01/16/2021] [Accepted: 01/19/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Sevoflurane (Sevo) is neuroprotective in brain damage, thus our objective was to further investigate the impact of Sevo treatment on nerve regeneration and repair of neurological deficit in brain damage rats by regulating miR-490-5p and cyclin-dependent kinases 1 (CDK1). METHODS The rat middle cerebral artery occlusion model was established. miR-490-5p and CDK1 levels in brain tissues were tested. The behavioral changes, the number of glial fibrillary acidic protein (GFAP) positive cells, ionized calcium-binding adapter molecule-1 (Iba-1) and Nestin mRNA expression, the survival and apoptosis of neurons in peripheral tissues of infarct areas were detected by a series of assays. Furthermore, the target relationship between miR-490-5p and CDK1 was verified. RESULTS miR-490-5p was reduced and CDK1 was raised in brain tissues of brain damage rats. Sevo raised miR-490-5p and decreased CDK1 to improve neurological deficits, reduce apoptotic neurons, suppress expression levels of GFAP and Iba-1, and increase Nestin expression and the number of surviving neurons in peripheral tissue in infarct area, and alleviate the pathological changes of brain tissues of brain damage rats. CDK1 was negatively regulated by miR-490-5p. CONCLUSION Our study presents that Sevo treatment is involved in neurogenesis and repair of neurological deficit of brain damage rats via up-regulating miR-490-5p and inhibiting CDK1.

Abstract
Liver cancer is the 7th utmost frequent neoplasm and the 4th principal source of cancer deaths. This malignancy is linked with several environmental and lifestyle-related factors emphasizing the role of epigenetics in its pathogenesis. MicroRNAs (miRNAs) have been regarded as potent epigenetic mechanisms partaking in the pathogenesis of liver cancer. Dysregulation of miRNAs has been related with poor outcome of patients with liver cancer. In the current manuscript, we provide a concise review of the results of recent studies about the role of miRNAs in the progression of liver cancer and their diagnostic and prognostic utility.

Abstract
Long non-coding RNA (lncRNA) small nucleolar RNA host gene 7 (SNHG7) plays a crucial role in the progression of pancreatic cancer (PC). SNHG7 is upregulated in PC; therefore, the purpose of the present study was to investigate the role and underlying mechanism of SNHG7 on PC progression. In the present study, the mRNA expression levels of SNHG7, microRNA(miR)-146b-5p and roundabout homolog 1 (Robo1) were measured via reverse transcription-quantitative PCR. Moreover, cell viability and apoptosis were assessed by MTT and flow cytometry assays, respectively. The ability of cells to migrate and invade was evaluated by Transwell assays. In addition, dual-luciferase reporter, RNA immunoprecipitation and RNA pull-down assays were conducted to assess the interaction between miR-146b-5p and SNHG7 or Robo1. The protein expression of Robo1 was measured via western blotting. Furthermore, mouse xenograft models were established to further investigate the effect of SNHG7 on PC progression in vivo. The results indicated that SNHG7 was highly expressed in PC tissues and cells. It was also found that SNHG7 was sponged by miR-146b-5p and that Robo1 was a target of miR-146b-5p. Moreover, it was demonstrated that SNHG7 knockdown inhibited cell proliferation, migration and invasion, as well as tumorigenesis and apoptosis of PC cells in vitro and in vivo by regulating miR-146b-5p. The results also suggested that miR-146b-5p overexpression inhibited the progression of PC cells by modulating Robo1. Furthermore, silencing of SNHG7 downregulated Robo1 expression by sponging miR-146b-5p. Collectively, the present results indicate that SNHG7 promotes PC progression by sponging miR-146b-5p and upregulating Robo1.

Abstract
Hepatocellular carcinoma (HCC) is a common primary liver cancer with a high incidence and mortality. This study was conducted to identify a long non-coding RNA (lncRNA) signature that may serve as a predictor for HCC prognosis.RNA-seq data were extracted from The Cancer Genome Atlas database. Differentially expressed genes, lncRNAs, and miRNAs were identified in HCC (n = 374) and control samples (n = 50) and used to screen prognosis-associated lncRNA signatures. The association of the lncRNA signature with HCC prognosis was analyzed and a competitive endogenous RNA regulatory network involving the lncRNA signature was constructed.A total of 199 mRNAs, 1092 lncRNAs, and 251 miRNAs were differentially expressed between HCC and control samples. Among these lncRNAs, 11 prognosis-associated lncRNAs were used to construct a lncRNA signature. Cox regression analysis showed that patients with higher risk scores of the lncRNA signature were at risk of poor prognosis. Four lncRNAs (including LINC01517, DDX11-AS1, LINC01136, and RP11-20J15.2) and 7 miRNAs (including miR-195, miR-199b, miR-326, miR-424, and let-7c) in the ceRNA network interacted with the upregulated gene E2F2, which was associated with the overall prognosis of patients with HCC.The 11-lncRNA signature might be useful for predicting the prognosis of patients with HCC.

Abstract
Background Hepatocellular carcinoma (HCC) is a malignant disease with a high mortality among primary HCC patients worldwide. Lots of studies have shown that lncRNAs are known as the biomarkers in diagnosis, treatment and prognosis of hepatocellular carcinoma. Therefore, clarifying the detailed function and mechanism of the lncRNA in the HCC progressing seems particularly important. Methods The TCGA and GEO database and RT-qPCR were used to analyse the expression of TRIM52-AS1 in HCC tissues and cell lines. Clinical data were collected to further analyze the correlation between indicators of clinical samples and the expression of TRIM52-AS1. CCK-8, plate clone and transwell assays were employed to evaluate the role of TRIM52-AS1 on cell proliferation, migration and invasion. Then, bioinformatics prediction, luciferase reporter, RNA immunoprecipitation (RIP), and RT-qPCR were employed to analyze the direct interaction among TRIM52-AS1, miR-218-5p and ROBO1. Additionally, the rescue function assays were used to verify that miR-218-5p/ROBO1 was the function downstream of TRIM52-AS1. Results TRIM52-AS1 was overexpressed in HCC according to the TCGA database and RT-qPCR assay. The expression of TRIM52-AS1 was higher in the metastatic foci compared with primary tumor according to the GEO database. Additionally, TRIM52-AS1 knockdown inhibited the proliferation and metastasis of HCC cells. TRIM52-AS1 could act as competitive endogenous RNA to regulate ROBO1 through miR-218-5p, then promoted the HCC cell progression. Conclusion TRIM52-AS1 is overexpressed in HCC and can promote the proliferation and metastasis of HCC cells through miR-218-5p/ROBO1 axis, then drives the HCC cell progression.

Abstract
Background As a key transcription factor, forkhead box protein 3 (FOXP3) plays an important role in the development and function of natural cluster of differentiation 4 [CD4 (+)] regulatory T cells (Treg cells). However, the function of FOXP3 in Lipopolysaccharide (LPS)-induced acute lung injury (ALI) through regulating miR-146b-5p is unclear. This research aimed to disclose the regulatory effect of the FOXP3-mediated miR-146b-5p/Roundabout 1 (Robo1)/NF-κB system on LPS-induced ALI in mice. Methods The mice were subjected to 5 mg/kg of LPS via intratracheal instillation to induce ALI and generate the ALI model. Mice was divided into five group, including control group, ALI group, ALI + FOXP3 group, the ALI + miR antagomir group and ALI + miR antagomir+ FOXP3 group. Lung tissue injury were detected by hematoxylin and eosin (HE) staining. Lung wet/dry weight ratio, total cells in bronchoalveolar lavage fluid (BALF), total protein in BALF and the polymorphonuclear leukocyte (PMN) in BALF were detected. The levels of tumor necrosis factor-α (TNF-α), Interleukin 6 (IL-6) and IL-1β were detected by enzyme-linked immunosorbent assay (ELISA) kit. The dual-luciferase reporter assay were used to detect the target relationship between FOXP3 and Robo1. Mice was divided into five group, including control group, ALI group, ALI + FOXP3 group, ALI + Robo1 group and ALI + FOXP3+ Robo1 group. The protein levels of FOXP3, Robo1 and p-p65 were detected by western bolt. The mRNA levels of miR-146b-5p and Robo1 were detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Results Although protein expression levels of FOXP3 were significantly down-regulated in the ALI model, the increased FOXP3 levels promoted an increase in miR-146b-5p. Compared with the control group, the ALI model group exhibited severe histopathologic injury, such as thickening of the alveolar wall, pulmonary congestion, and decreased alveolar numbers. By mediating the overexpression of miR-146b-5p, FOXP3 also increased alveolar clearance and inhibited inflammatory responses in the ALI model. Importantly, Robo1 is a potential target of miR-146b-5p. Conclusions FOXP3 could inhibit NF-κB activation, reduce lung pathological damage, and inhibit inflammatory responses by mediating the miR-146b-5p/Robo1/NF-κB system in the ALI model. These results may provide a new potential target for the treatment of ALI disease.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that function as posttranscriptional gene regulators. Among a pool of >2600 known human mature miRNAs, only a small subset have been functionally interrogated and a further smaller pool shown to be associated with the pathogenesis of a variety of diseases suggesting their critical role in maintaining homeostasis. Here, we draw your attention to one such miRNA, miR-490, that has been reported to be deregulated in a myriad of diseases (23 diseases) ranging from cardiomyopathy, depression, and developmental disorders to many cancer types (28 cancer types), such as hepatocellular carcinoma, gastric cancer, cancers of the reproductive and central nervous system among others. The prognostic and diagnostic potential of miR-490 has been reported in many diseases including cancer underlining its clinical relevance. We also collate a complex plethora of epigenetic (histone and DNA methylation), transcriptional (TF), and posttranscriptional (lncRNA and circRNA) mechanisms that have been shown to tightly regulate miR-490 levels. The targets of miR-490 involve a range of cancer-related genes involved in the regulation of various cancer hallmarks like cell proliferation, migration, and invasion, apoptotic cell death, angiogenesis, and so forth. Overall, our in-depth review highlights for the first time the emerging role of miR-490 in disease pathology, diagnosis, and prognosis that assigns a unique therapeutic potential to miR-490 in the era of precision medicine.

Abstract
Hepatocellular Carcinoma (HCC) currently remains one of the most lethal malignancies worldwide. Recently, long non-coding RNAs (lncRNAs) had been demonstrated to play a crucial role in the progression of multiple human cancers, including HCC. In this study, we found that lncRNA DUXAP8 was upregulated in tumor samples and served as an oncogene in HCC. Bioinformatics analysis showed that DUXAP8 was significantly associated with the regulation of centrosome organization, homologous recombination, meiotic cell cycle process, sister chromatid segregation, nuclear chromosome segregation, and RNA export from the nucleus. The knockdown of DUXAP8 significantly suppresses cell proliferation and the cell cycle but induces cell apoptosis in HCC. Mechanically, the present study showed that DUXAP8 serves as a sponge of MiR-490-5p to promote the expression of BUB1 in HCC. Although the underlying regulatory mechanisms of DUXAP8 in HCC require further investigation, this study, for the first time, showed that DUXAP8 can serve as a new therapeutic target for HCC.

Abstract
Background: Hepatocellular carcinoma (HCC) is one of the most common malignancies with high invasion and metastasis capacities. Circular RNAs (circRNAs) were evidenced to take part in the progression of multifarious cancers, including HCC. However, the role of circ_0091579 in HCC progression has not been fully described. This study aimed to explore the function of circ_0091579 and its potential regulatory mechanism in the progression of HCC. Materials and Methods: The expression of circ_0091579, microRNA-490-5p (miR-490-5p), and cancer susceptibility candidate 3 (CASC3) in HCC tissues and cells was detected by quantitative real-time polymerase chain reaction. The circular characteristic and stability of circ_0091579 were verified by RNase R digestion and actinomycin D reaction assays. Cell proliferation, migration, and invasion were determined by methyl thiazolyl tetrazolium assay and Transwell assay, respectively. The level of glycolysis was evaluated by glucose consumption and lactate production. The levels of proteins were examined by Western blot. The interaction between miR-490-5p and circ_0091579 or CASC3 was certified by Dual-luciferase reporter assay. Results: circ_0091579 and CASC3 were upregulated, while miR-490-5p was downregulated in HCC tissues and cells. Silencing of either circ_0091579 or CASC3 suppressed cell proliferation, migration, invasion, and glycolysis in HCC cells. Moreover, miR-490-5p was verified to directly bind to circ_0091579 and CASC3. Circ_0091579 upregulated CASC3 by sponging miR-490-5p in HCC cells to promote cell proliferation, invasion, and migration. Conclusion: circ_0091579 promoted cell proliferation, migration, invasion, and glycolysis partially through miR-490-5p/CASC3 axis in HCC cells.

Abstract
Context
Immune system has been claimed as the ‘main switch’ of tissue or organ regeneration. Among immune cells, macrophages stand out as important modulators in mutiple regeneration models, such as planarian, axolotl, mammalian hair and liver. As a unique model for mammals, deer antler is considered to ideal for studying complete mammalian organ regeneration. Studies have found that antler regeneration is a stem cell-based process and antler stem cells locate in the pedicle periosteum (PP). Although the regulatory roles of the immune system in other regeneration models have been extensively studied, they remain unstudied in antler regeneration.
Aims
To explore the possible role of macrophages in the PP cells (PPCs).
Methods
We treated PPCs with a macrophage-conditioned medium (MCM) and detected effects of MCM on proliferation, migration and apoptosis of the PPCs, and identified differentially expressed genes by using the RNA-seq technique.
Key results
We found that MCM enhanced proliferation rate and migration rate significantly and stimulated apoptosis of the PPCs. Using the RNA-seq technique, we identified 112 differentially expressed genes in the PPCs (38 downregulated and 74 upregulated) after the MCM treatment. Furthermore, gene-ontology annotation analyses showed that the upregulated genes were mainly involved in cell adhesion, chemotaxis, wound healing, growth factor-stimulated responses, and bone formation, and the downregulated genes were involved in regulation of biosynthesis.
Conclusions
MCM had a great influence on the antler stem cells, and macrophages might regulate antler regeneration through altering the microenvironment and gene-expression profiles of the PPCs.
Implications
We believe that the results of the present study would facilitate the discovery of the roles of immune system in antler stem cells and, thus, mammalian organ regeneration in general.

Abstract
MicroRNA (miRNA/miR) has been identified to be a promising tool in treating pharyngolaryngeal cancer. The present study aimed to investigate the role of miR‑490‑5p in the regulation of proliferation, migration, invasion and epithelial‑mesenchymal transition (EMT) of pharyngolaryngeal cancer cells. The data of miR‑490‑5p expression levels of 45 cases were obtained from the People's Hospital of Xinjiang Uygur Autonomous Region, and the prediction of the target of miR‑490‑5p was conducted by bioinformatics and verified using a luciferase assay. Cell viability was determined by cell counting kit‑8. Migration and invasion rates were measured by wound healing test and Transwell apparatus, respectively. Colony formation rate was measured by plate colony formation assay. mRNA and protein levels were determined by quantitative polymerase chain reaction and western blotting, respectively. miR‑490‑5p expression was significantly depressed in primary pharyngolaryngeal cancer tissues and cell lines, leading to an unfavorable prognosis. Evidently, miR‑490‑5p overexpression decreased the cell viabilities of BICR 18 and FaDu cells. Mechanically, miR‑490‑5p could target mitogen‑activated protein kinase kinasekinase 9 (MAP3K9). The overexpression of MAP3K9 could promote cell viability, migration and invasion rates, EMT process and ability of cloning, miR‑490‑5p could target MAP3K9 and further modulate the proliferation, migration, invasion and EMT of pharyngolaryngeal cancer cells. The results of the present study provide a novel entry point to the treatment of pharyngolaryngeal cancer.

Abstract
BACKGROUND PDCoV (Porcine Deltacoronavirus) is a novel porcine coronavirus that causes intestinal necrosis of piglets, thinning of the intestinal wall and severe villus atrophy in the small intestine. PDCoV is a highly contagious infectious disease characterized by diarrhea, dehydration and vomiting. It has been reported that lncRNA has a significant effect on viral replication and increased or decreased virulence. At present, there is almost no research on lncRNA related to PDCoV infection. With the development of the research, a large number of lncRNAs related to PDCoV infection have been discovered. Identifying the role of these lncRNAs in the infection process facilitates the screening of diagnostically significant biomarkers. RESULTS Using high throughput sequencing to screen differentially expressed long non-coding RNA (lncRNA) during PDCoV infection, we identified 99, 41 and 33 differentially expressed lncRNAs in the early, middle and late stages of infection, respectively. These lncRNAs were involved in glycolysis / gluconeogenesis, histidine metabolism and pentose and Chloroalkane and chloroalkene degradation pathway. We obtained expression data of miRNAs, lncRNAs and mRNAs during PDCoV infection and constructed and investigated an interaction network. The qRT-PCR validation results of 6 differentially expressed lncRNAs were consistent with RNA-Seq results. CONCLUSIONS This study is the first to examine differentially expressed lncRNAs after PDCoV infection of piglets. These results can provide new insights into PDCoV infection and antiviral strategies.

Abstract
Previous studies demonstrated microRNA-185 (miR-185) as a tumor suppressive microRNA (miRNA) in various types of cancer. The current study aimed to verify this finding in hepatocellular carcinoma (HCC) and explored the downstream channel of miR-185-5p. We detected miR-185-5p and Rho-associated coiled-coil containing protein kinase 2 (ROCK2) mRNA and protein levels by reverse transcription-quantitative PCR (RT-qPCR) and western blotting in HCC tissues and cell lines. Luciferase reporter assay proved the direct relationship between miR-185-5p and ROCK2. Cell migration and invasion were assessed via Transwell assay. miR-185-5p level was reduced in HCC tissues and cell lines. miR-185-5p overexpression impeded migration and invasion of HCC cells. Moreover, miR-185-5p directly targeted ROCK2 which was repressed by miR-185-5p in HCC. In addition, ROCK2 contributed to cell metastasis of HCC. In summary, miR-185-5p inhibited cell metastasis of HCC by suppressing ROCK2. The novel miR-185/ROCK2 axis shows potential in improving the therapies of HCC and enhancing HCC survival.

Oncol Lett 2019; 17:4437-4442. [PMID: 30988813 PMCID: PMC6447928 DOI: 10.3892/ol.2019.10143] [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: 10/26/2018] [Accepted: 02/19/2019] [Indexed: 12/12/2022] Open
Abstract
Changes in the expression of miR-490-5p, miR-148a-3p and miR-608 in bladder cancer tissues were studied. A total of 30 patients with bladder cancer who had surgical resection in the Hunan Provincial People's Hospital (Changsha, China) from April 2015 to August 2016 were selected. RT-qPCR was used to detect the expression levels of miR-490-5p, miR-148a-3p and miR-608. The expression vectors of miR-490-5p, miR-148a-3p and miR-608 were respectively transfected and divided into three groups: blank cell group, gene transfection group (groups A-C) and negative transfection group (NC group). CCK8 was used to detect cell proliferation and flow cytometry was used to detect the condition of apoptosis of each group, and the Transwell chamber was used to detect the invasion ability of the cells. After the transfection, the expression level of miR-490-5p in group A was significantly higher than that in the NC and blank groups, and the expression level of miR-148a-3p in group B was significantly higher than that in the NC and blank groups. The expression level of miR-608 in group C was significantly higher than that in the NC and blank groups (P<0.001). The survival rates of the cells in groups A-C were significantly lower than those in the NC and blank groups at 48 and 72 h (P<0.001). After the transfection, the number of invasive cells and the apoptosis rates in groups A-C were significantly higher than those in the NC and blank groups (P<0.05). miR-490-5p, miR-148a-3p and miR-608 promoted proliferation of bladder cancer T24 cells and inhibited apoptosis of the cells and showed potential to become a new target for the future treatment of bladder cancer.

Mol Clin Oncol 2019; 10:331-338. [PMID: 30847170 PMCID: PMC6388501 DOI: 10.3892/mco.2019.1795] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Accepted: 12/10/2018] [Indexed: 12/16/2022] Open
Abstract
MicroRNAs (miRNAs/miRs) are a novel class of gene regulators that may be involved in tumor chemoresistance. Recently, specific miRNA expression profiles have been identified in adult glioblastoma (aGBM), but there are only limited data available on the role of miRNAs in pediatric GBM (pGBM). In the present study, the expression profile of miRNAs was examined in seven pGBMs and three human GBM cell lines (U87MG, A172 and T98G), compared with a non-tumoral pool of pediatric cerebral cortex samples by microarray analysis. A set of differentially expressed miRNAs was identified, including miR-490, miR-876-3p, miR-876-5p, miR-448 and miR-137 (downregulated), as well as miR-501-3p (upregulated). Through bioinformatics analysis, a series of target genes was predicted. In addition, similar gene expression patterns in pGBMs and cell lines was confirmed. Of note, drug resistant T98G cells had upregulated nuclear casein kinase and cyclin-dependent kinase substrate 1 (NUCKS1) expression, a protein overexpressed in many tumors that serves an important role in cell proliferation and progression. On the basis of the present preliminary report, it could be intriguing to further investigate the relationship between each of the identified differentially expressed miRNAs and NUCKS1, in order to clarify their involvement in the multi-drug resistance mechanism of pGBMs.
