Exosomal microRNA profiling to identify hypoxia-related biomarkers in prostate cancer. Oncotarget 2018; 9:13894-13910. [PMID: 29568403 PMCID: PMC5862624 DOI: 10.18632/oncotarget.24532] [Citation(s) in RCA: 48] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2017] [Accepted: 02/10/2018] [Indexed: 12/21/2022] Open
Abstract
Hypoxia and expression of hypoxia-related biomarkers are associated with disease progression and treatment failure in prostate cancer (PCa). We have reported that exosomes (nanovesicles of 30-150 nm in diameter) secreted by human PCa cells under hypoxia promote invasiveness and stemness in naïve PCa cells. Here, we identified the unique microRNAs (miRNAs) loaded in exosomes secreted by PCa cells under hypoxia. Using TaqMan® array microRNA cards, we analyzed the miRNA profile in exosomes secreted by human PCa LNCaP cells under hypoxic (ExoHypoxic) and normoxic (ExoNormoxic) conditions. We identified 292 miRNAs loaded in both ExoHypoxic and ExoNormoxic. The top 11 miRNAs with significantly higher level in ExoHypoxic compared to ExoNormoxic were miR-517a, miR-204, miR-885, miR-143, miR-335, miR-127, miR-542, miR-433, miR-451, miR-92a and miR-181a; and top nine miRNA with significantly lower expression level in ExoHypoxic compared to ExoNormoxic were miR-521, miR-27a, miR-324, miR-579, miR-502, miR-222, miR-135b, miR-146a and miR-491. Importantly, the two differentially expressed miRNAs miR-885 (increased expression) and miR-521 (decreased expression) showed similar expression pattern in exosomes isolated from the serum of PCa patients compared to healthy individuals. Additionally, miR-204 and miR-222 displayed correlated expression patterns in prostate tumors (Pearson R = 0.66, p < 0.0001) by The Cancer Genome Atlas (TCGA) prostate adenocarcinoma (PRAD) genomic dataset analysis. Overall, the present study identified unique miRNAs with differential expression in exosomes secreted from hypoxic PCa cells and suggests their potential usefulness as a biomarker of hypoxia in PCa patients.

Potential role of microRNA‑223‑3p in the tumorigenesis of hepatocellular carcinoma: A comprehensive study based on data mining and bioinformatics. Mol Med Rep 2017; 17:2211-2228. [PMID: 29207133 PMCID: PMC5783470 DOI: 10.3892/mmr.2017.8167] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2017] [Accepted: 10/02/2017] [Indexed: 02/07/2023] Open
Abstract
The aims of the present study were to examine the potential role of microRNA‑233‑3p (miR)‑223‑3p in the tumorigenesis of hepatocellular carcinoma (HCC), and to investigate its diagnostic accuracy and potential molecular mechanisms. The expression data of miR‑223‑3p in HCC were obtained from the Gene Expression Omnibus (GEO). Data for the precursor miR‑223 were obtained from The Cancer Genome Atlas (TCGA). The diagnostic role of miR‑223‑3p was identified by the receiver operating curve (ROC), and the diagnostic value of miR‑223‑3p in HCC was calculated from qualified reports in the literature. In addition, associated data from the GEO, TCGA and qualified experiments were pooled for comprehensive meta‑analysis. Genes, which intersected between online prediction databases, natural language processing and differentially expressed genes from TCGA were regarded as potential targets of miR‑223‑3p in HCC. The Gene Ontology enrichment analysis and the Kyoto Encyclopedia of Genes and Genomes pathways of potential targets were performed using the Database for Annotation, Visualization and Integrated Discovery. The protein‑protein interactions were mapped using the Search Tool for the Retrieval of Interacting Genes. Among 15 qualified microarray data sets from GEO, seven showed that a significantly lower level of miR‑223‑3p was present in the HCC tissues, compared with that in non‑cancerous tissues (P<0.05). In addition, five GEO data sets revealed diagnostic values of miR‑223‑3p, with an area under the curve (AUC) of >0.80 (P<0.05). The diagnostic accuracy of the precursor miR‑223 in TCGA was also calculated (AUC=0.78, P<0.05). Similarly, the precursor miR‑223 showed a higher level of downregulation in HCC tissues, compared with that in healthy controls in TCGA (P<0.001). A summary ROC was also calculated as 0.89 (95% CI, 0.85‑0.91) in the meta‑analysis. A total of 72 potential targets were extracted, mainly involved in the terms 'microRNAs in cancer', 'ATP binding' and 'prostate cancer'. Five potential target genes were considered the hub genes of miR‑223‑3p in HCC, including checkpoint kinase 1, DNA methyltransferase 1, baculoviral IAP repeat containing 5, kinesin family member 23, and collagen, type I, α1. Based on TCGA, the hub genes were significantly upregulated in HCC (P<0.05). Collectively, these results showed that miR‑223‑3p may be crucial in HCC carcinogenesis showing high diagnostic accuracy, and may be mediated by several hub genes.

Abstract
Ultrasonography is the first choice of lymph node metastasis (LNM) detection which is crucial for therapeutic options of papillary thyroid cancer (PTC). However, the sensitivity of ultrasonography in detecting LNM of PTC is relatively low; especially in central LNM. MiR-324-5p has been reported to play important roles in the metastasis of various cancers. To explore the relationship between miR-324-5p and LNM in PTC, quantitative real-time polymerase chain reaction was performed in PTC tissue and fine needle aspiration (FNA) washout successively. Its correlation with LNM of PTC was analyzed. The clinicopathological and sonographic factors relating to LNM were also studied. Additionally, the function assay of miR-324-5p in PTC cells was conducted. Current study demonstrated that age was an independent protective factor and multifocality, advanced TNM stage, increased transverse diameter of thyroid nodule, ultrasound suspected LNM were independent risk factors of LNM. MiR-324-5p promoted proliferation, migration and invasion of PTC cell line. MiR-324-5p could serve as a candidate predictor along with ultrasonography in predicting LNM, especially central LNM of unifocal papillary thyroid microcarcinoma without extracapsular spread.

Abstract
BACKGROUND The aim of this study was to explore the underlying molecular mechanism and potential molecular biomarkers of chronic pancreatitis (CP) and construct a miRNA-mRNA regulation network. METHODS To explore the involvement of miRNAs in CP, we downloaded the miRNA and mRNA expression profiles of CP patients and healthy controls and identified the differentially expressed miRNAs and genes. Functional analysis was conducted and significant pathways were utilized. Finally, the miRNA-mRNA regulation network of CP was constructed. RESULTS A total of 44 miRNA risk gene pathway relationships were identified, and a complex regulation network was constructed with 3 genes (ABL1, MYC, and ANAPC13) having the highest degree in affecting the network of CP. Importantly, 4 risk genes (NOTCH3, COX5A, THBS1, and KARS) and 1 risk miRNA (hsa-miR-324-5p) were identified with high prediction accuracy. CONCLUSIONS In conclusion, we analyzed miRNAs and mRNAs expression profiles in CP, 1 risk miRNA, and 4 risk genes were identified with high prediction accuracy as biomarkers of CP. Although further evaluation in clinical study is needed, our findings provide new insights into the pathogenesis of CP and may improve the diagnosis and therapy by identifying novel targets.

Oxygen tension regulates the miRNA profile and bioactivity of exosomes released from extravillous trophoblast cells - Liquid biopsies for monitoring complications of pregnancy. PLoS One 2017; 12:e0174514.

Abstract
Our understanding of how cells communicate has undergone a paradigm shift since the recent recognition of the role of exosomes in intercellular signaling. In this study, we investigated whether oxygen tension alters the exosome release and miRNA profile from extravillous trophoblast (EVT) cells, modifying their bioactivity on endothelial cells (EC). Furthermore, we have established the exosomal miRNA profile at early gestation in women who develop pre-eclampsia (PE) and spontaneous preterm birth (SPTB). HTR-8/SVneo cells were used as an EVT model. The effect of oxygen tension (i.e. 8% and 1% oxygen) on exosome release was quantified using nanocrystals (Qdot®) coupled to CD63 by fluorescence NTA. A real-time, live-cell imaging system (Incucyte™) was used to establish the effect of exosomes on EC. Plasma samples were obtained at early gestation (<18 weeks) and classified according to pregnancy outcomes. An Illumina TrueSeq Small RNA kit was used to construct a small RNA library from exosomal RNA obtained from EVT and plasma samples. The number of exosomes was significantly higher in EVT cultured under 1% compared to 8% oxygen. In total, 741 miRNA were identified in exosomes from EVT. Bioinformatic analysis revealed that these miRNA were associated with cell migration and cytokine production. Interestingly, exosomes isolated from EVT cultured at 8% oxygen increased EC migration, whilst exosomes cultured at 1% oxygen decreased EC migration. These changes were inversely proportional to TNF-α released from EC. Finally, we have identified a set of unique miRNAs in exosomes from EVT cultured at 1% oxygen and exosomes isolated from the circulation of mothers at early gestation, who later developed PE and SPTB. We suggest that aberrant exosomal signalling by placental cells is a common aetiological factor in pregnancy complications characterised by incomplete SpA remodeling and is therefore a clinically relevant biomarker of pregnancy complications.

Abstract
Sp1 belongs to the 26 member strong Sp/KLF family of transcription factors. It is a paradigm for a ubiquitously expressed transcription factor and is involved in regulating the expression of genes associated with a wide range of cellular processes in mammalian cells. Sp1 can interact with a range of proteins, including other transcription factors, members of the transcription initiation complex and epigenetic regulators, enabling tight regulation of its target genes. In this review, we discuss the mechanisms involved in Sp1-mediated transcriptional regulation, as well as how a ubiquitous transcription factor can be involved in establishing a tissue-specific pattern of gene expression and mechanisms by which its activity may be regulated. We also consider the role of Sp1 in human diseases, such as cancer.

Abstract
MicroRNA-22-3p (miR-22-3p) is downregulated in hepatocellular carcinoma (HCC), which contributes to the development and progression of HCC. In this study, berberine treatment upregulated miR-22-3p expression in HepG2 cells. Therefore, we investigated whether berberine suppresses the proliferation of HCC cells and explored the underlying mechanism. The HCC HepG2 cell line was treated with a gradient of berberine concentrations (0-300 μM) for 48 h, and 100 μM berberine inhibited cell growth at 24 h. The HepG2 cells were then incubated with 100 μM berberine for 0-48 h, and after treatment for 24 h, berberine markedly suppressed HepG2 cell growth and significantly upregulated miR-22-3p expression. Berberine also downregulated the expression of SP1, CCND1, and BCL2, determined with western blotting. Dual luciferase reporter assays and western blot analyses showed that miR-22-3p directly targeted SP1, thereby suppressing the expression of its downstream targets, CCND1 and BCL2. SP1 knockdown with small interfering RNA also reduced CCND1 and BCL2 expression in HepG2 cells. Therefore, we conclude that berberine treatment suppresses cancer cell growth by regulating miR-22-3p and SP1 and its downstream targets, CCND1 and BCL2, in HCC.

Abstract
The expression and functions of microRNA (miR)-411 have been investigated in several types of cancer. However, until now, miR-411 in human breast cancer has not been examined. The present study investigated the expression, biological functions and molecular mechanisms of miR‑411 in human breast cancer, discussing whether it offers potential as a therapeutic biomarker for breast cancer in the future. The expression levels of miR‑411 in human breast cancer tissues and cells were measured using reverse transcription‑quantitative polymerase chain reaction analysis. Following transfection with miR‑411 mimics, an MTT assay, cell migration and invasion assay, western blot analysis and luciferase assay were performed in human breast cancer cell lines. According to the results, it was found that miR‑411 was significantly downregulated in breast cancer, and associated with lymph node metastasis and histological grade. Additionally, it was observed that miR‑411 suppressed cell growth, migration and invasion in the breast cancer cells. The present study also provided the first evidence, to the best of our knowledge, that miR‑411 was likely to directly target specificity protein 1 in breast cancer. These findings indicated that miR‑411 may be used a therapeutic biomarker for the treatment of breast cancer in the future.

Abstract
Background Approximately 2–10% of the patients with hepatolithiasis may develop cholangiocarcinoma (CCA). Despite recent advances in the treatment of cancers, the 5-year survival rate for CCA patients currently remains poor, primarily due to early local invasion and distant metastasis of the cancer. This study aimed to investigate miR-200a expression in combined hepatolithiasis and CCA as well as its correlation with the clinical features of CCA. Material/Methods miR-200a expression in combined hepatolithiasis and CCA was detected by real-time reverse transcription PCR (qRT-PCR). Its correlation with the clinicopathology of CCA was analyzed by t-tests. The effect of miR-200a on the proliferation CCA cells was determined by MTT assay. The effect of miR-200a on the invasive ability of CCA cells was assessed by Boyden chamber test. Results The expression level of MiR-200a in patients with combined hepatolithiasis and CCA was significantly decreased compared with patients with only hepatolithiasis (P<0.01). Furthermore, miR-200a expression in hepatic duct cancer RBE cells was substantially reduced compared with hepatolithiasis group (P<0.01). Correlation analysis showed that abnormal expression of miR-200a was only associated with the differentiation degree and metastasis of CCA. MiR-200a transfection significantly inhibited the proliferation and invasion of REB cells (P<0.01). Conclusions MiR-200a may suppress the proliferative and invasive ability of REB cells. The reduced miR-200a expression might be correlated with the development and progression of CCA.

Abstract
Prostate cancer (PC) is a serious health problem all over the world. Cell proliferation plays a major role in the tumorigenesis of PC. It is reported that microRNAs (miRNAs) played crucial roles in the regulation of cell proliferation. However, the underlying mechanism of miRNAs in PC has not been intensively investigated. In the present study, the effect of miR-592 on the cell proliferation of PC was investigated. The results showed that miR-592 was significantly upregulated in PC cell and PC tissues. To investigate the biological roles of miR-592, we induced either the up- or downregulation of miR-592 expression by transfecting DU145 PC cells with miR-592 mimics or miR-592 inhibitor. Our results demonstrated that the upregulation of miR-592promoted cell growth, while miR-592 inhibitor showed the opposite effect. Further experiment revealed that miR-592 repressed the expression of FOXO3 by directly targeting the 3'UTR of the FOXO3 transcript, which resulted in upregulating of the expression of cyclin D1 and downregulating of the expression of p21. In sum, our data indicated a novel aspect of the miR-592 in the molecular etiology of PC.
