[PMID: 31782506 PMCID: PMC6911154 DOI: 10.1042/bsr20190193] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Revised: 11/06/2019] [Accepted: 11/28/2019] [Indexed: 02/07/2023] Open
Abstract
Colorectal cancer (CRC) is the third most common malignant tumor worldwide and is a serious threat to human health. MicroRNAs (miRNAs) play a key role in oncogenesis and cancer progression. MiRNA-125 (miR-125) is an important miRNA that is dysregulated in several kinds of cancers. Thus, we investigated the expression and effects of miR-125 and Transcriptional co-activator with PDZ-binding motif (TAZ) for a better understanding of the underlying mechanism of tumor progression in CRC, which may provide an emerging biomarker for diagnosis and treatment of CRC. We measured the expression levels of miR-125 in CRC tissues, adjacent tissues, and cell lines (e.g. HCT116, SW480, FHC) by quantitative real-time polymerase chain reaction (qRT-PCR). The effect of miR-125 on proliferation and invasion in CRC cells was detected by Cell Counting Kit-8 (CCK-8), clone formation assay, and transwell assay. Western blotting and qRT-PCR were used to investigate the expression of TAZ after knocking down miR-125 in HCT116 cells or overexpressing miR-125 in SW480 cells. MiR-125 was significantly down-regulated in CRC compared with pericarcinomatous tissue from 18 patients. An miR-125 inhibitor promoted CRC cell proliferation and invasion, while miR-125 mimic had the opposite effect. Moreover, we found that TAZ was an miR-125 target and the siRNA knockdown of TAZ could reverse the effect of the miR-125 inhibitor on proliferation and invasion in HCT116 cells. The present study shows that miR-125 suppresses CRC proliferation and invasion by targeting TAZ.

Cell Biochem Funct 2019; 38:28-37. [PMID: 31710389 DOI: 10.1002/cbf.3444] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2019] [Revised: 08/26/2019] [Accepted: 09/22/2019] [Indexed: 01/02/2023]
Abstract
Gastric cancer (GC) is one of the most common causes of cancer-related death worldwide, and outstanding biomarkers for therapeutic targets or predicting GC survival are still lacking. Increasing evidence indicated that nucleolar and spindle associated protein 1 (NUSAP1) involved in regulating the progression of various cancers; however, its specific role in GC remained unclear. In this study, we found that NUSAP1 was upregulated in the GC tissues and cell lines via analysing data from The Cancer Genome Atlas (TCGA), gene expression omnibus (GEO), qRT-PCR, and western blot assays. Patients with high NUSAP1 expression levels showed shorter free-progression survival (FPS), larger tumour size, and higher lymphatic metastasis rate compared with those with low NUSAP1 expression. Further functional experiments revealed knockdown of NUSAP1 could inhibit the growth, migration, and invasion of GC cells in vitro and vivo. Additionally, silencing NUSAP1 induced G0/G1 phase arrest, apoptosis, and suppressed the epithelial-mesenchymal transition (EMT) process. Finally, we performed gene set enrichment analysis (GSEA) and observed NUSAP1 was positive with mTORC1 signalling pathway, which was verified by the subsequent immunoblotting. In conclusion, our findings suggested that NUSAP1 contributed to GC progression and may act as a potential therapeutic target for GC. SIGNIFICANCE OF THE STUDY: Our results firstly illuminated that NUSAP1 expression was significantly upregulated in GC tissues and predicted poor FPS. Silencing it could attenuate GC progression via inhibiting mTORC1 signalling pathway. Hence, NUSAP1 may act as a promising therapy target for GC.

Abstract
Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related deaths among cancer patients. Genes correlated with the progression and prognosis of HCC are critically needed to be identified. In the present study, 3 Gene Expression Omnibus (GEO) datasets (GSE46408, GSE65372 and GSE84402) were used to analyze the differentially expressed genes (DEGs) between HCC and non-tumor liver tissues. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted to clarify the functional roles of DEGs. A protein-protein interaction network was established to screen the hub genes associated with HCC. The prognostic values of hub genes in HCC patients were analyzed using The Cancer Genome Atlas (TCGA) database. The expression levels of hub genes were validated based on ONCOMINE, TCGA and Human Protein Atlas (HPA) databases. Notably, 56 upregulated and 33 downregulated DEGs were markedly enriched under various GO terms and four KEGG terms. Among these DEGs, 10 hub genes with high connectivity degree were identified, including cyclin B1, cyclin A2, cyclin B2, condensin complex subunit 3, PDZ binding kinase, nucleolar and spindle-associated protein 1, aurora kinase A, ZW10 interacting kinetochore protein, protein regulator of cytokinesis 1 and kinesin family member 4A. The upregulated expression levels of these hub genes in HCC tissues were further confirmed by ONCOMINE, TCGA, and HPA databases. Additionally, the increased mRNA expression of each hub gene was related to the unfavorable disease-free survival and overall survival of HCC patients. The present study identified ten genes associated with HCC, which may help to provide candidate targets for the diagnosis and treatment of HCC.

Role of Non-Coding RNAs in the Progression of Liver Cancer: Evidence from Experimental Models. Cancers (Basel) 2019; 11:cancers11111652.

Abstract
Liver cancer is a devastating cancer that ranges from relatively rare (around 2% of all cancers in the United States) to commonplace (up to 50% of cancers in underdeveloped countries). Depending upon the stage of pathogenesis, prognosis, or functional liver tissue present, transplantation or partial hepatectomy may be the only available treatment option. However, due to the rise in metabolic syndrome and the increasing demand for livers, patients often wait months or years for available organs. Due to this shortage, doctors must have other treatment options available. One promising area of cancer research lies in understanding the role of regulatory non-coding RNAs (ncRNAs) as oncogenic drivers and potential targets for prospective therapies. While the role of these ncRNAs was not initially clear, many of them have since been recognized to function as important players in the regulation of gene expression, epigenetic modification, and signal transduction in both normal and cancer cell cycles. Dysregulation of these different ncRNA subtypes has been implicated in the pathogenesis and progression of many major cancers including hepatocellular carcinoma. This review summarizes current findings on the roles noncoding RNAs play in the progression of liver cancer and the various animal models used in current research to elucidate those data.

Abstract
Stable cartilage regeneration has always been a challenge in both tissue engineering research and clinical practice. This study explored the feasibility of using a chondrocyte sheet technique stimulated by microRNAs to regenerate cartilage. We tested the involvement of hsa-miR-193b-3p in the microtia patient remnant auricular chondrocyte extracellular matrix (ECM). We observed in vitro chondrocyte proliferation, ECM synthesis, as well as the increase in the expression of type II collagen (COL2A1) and decrease in the expression of matrix metalloproteinase 16 (MMP16) of the chondrocyte sheets. COL2A1 deposition and MMP16 degradation of regenerative cartilage tissue were examined in vivo. A dual-luciferase reporter showed that the MMP16 gene was the direct target of miR-193b-3p. These results suggested that miR-193b-3p promotes chondrocyte sheet ECM synthesis by inhibiting MMP16. Since the evidence suggests that MMP16 is a critical regulator of chondrocyte ECM, this finding points the way towards a method that both strengthens the ECM and inhibits MMPs.

Abstract
Non-small cell lung cancer (NSCLC) is accounted for 80% to 85% of the total lung cancer cases and still a difficult problem to solve at present. The present study was aimed to explore the effect of S100A6 on the proliferation, invasion, migration and angiogenesis in lung cancer cell lines with the change of miR-193a expression and P53 acetylation. The expression of S100A6, CDK2, cyclinD1, VEGF, ANGII, anti-acetylp53 (K373), K-AC, P21 and Noxa were analyzed by western blot analysis. RT-qPCR analysis was used to confirm the transfection effects. CCK-8 assay and flow cytometry were reflecting the cell proliferation. Wound healing assay and transwell assay were evaluating the cell invasion and migration. The dual-luciferase reporter assay was to confirm the S100A6 as a target of miR-193a. Immunofluorescence and immunohistochemical analysis were analyzing the S100A6 expression in cells and tumor tissues, respectively. As a result, S100A6 expression was increased in lung cancer cell lines and S100A6 expressed the highest in A549 cells which was chosen for the subsequent experiment. S100A6 overexpression promoted the proliferation, invasion, migration and angiogenesis of lung cancer cells with the promotion of degradation of P53 acetylation. In addition, S100A6 was demonstrated to be a target of miR193a. Moreover, miR193a expression was decreased in lung cancer cell lines and miR193a expressed the lowest in A549 cells which was chosen for the subsequent experiment. And, miR193a overexpression inhibited the proliferation, invasion, migration and angiogenesis of lung cancer cells with the enhancement of P53 acetylation. The effects of S100A6 overexpression and miR193a overexpression on tumor growth in vivo experiments were the same with that in the cell experiments. In conclusion, this study indicated that S100A6 overexpression could promote the proliferation, invasion, migration and angiogenesis of lung cancer cells by inhibiting the P53 acetylation and miR193a overexpression could reversed the above effects by decreasing the S100A6 expression in both vitro and vivo experiments.

Abstract
Age-related cataract is one of the prior causes of blindness and the incidence rates of cataract are even rising. Oxidative stress plays an important role in the pathogenesis of cataracts. Under oxidative stress, lens epithelial cell (LEC cell) apoptosis is activated, which might lead to the opacity of the lens and accelerate the progression of cataract development. Meanwhile, autophagy is also active to face oxidative stress. miRNAs have been reported to involve cataract. However, the underlying mechanism is not clear. The present study aimed to investigate the regulatory effect of miR23b-3p on apoptosis and autophagy in LEC cells under oxidative stress. The expression levels of miR-23b-3p were examined in age-related cataract tissues and LEC cells treated with hydrogen peroxide, showing that miR23b-3p expression levels were upregulated. Knockdown of miR23b-3p expression in LEC cells brought about apoptosis significantly decreased while autophagy significantly increased during hydrogen peroxide. We predicted microRNA miRNA-23b-3p might participate in regulating silent information regulator 1 (SIRT1) by bioinformatics database of TargetScan. Luciferase reporter assays confirmed that miRNA-23b-p could suppress SIRT1 expression by binding its 3'UTR. In addition, overexpression or knockdown of miR-23b-3p could decrease or increase SIRT1 expression, which indicated that Mir-23b-3p could suppress SIRT1 expression. In addition, enhanced SIRT1 could attenuate the regulation of cell apoptosis and autophagy induced by overexpression of miR-23b-3p. Taken together, our findings revealed that miR-23b-3p regulated apoptosis and autophagy via suppressing SIRT1 in LEC cell under oxidative stress, which could provide new ideas for clinical treatment of cataract.

Abstract
Background: The enhanced ability of cancer metastasis is the major cause for the cancer-related death of hepatocellular carcinoma (HCC). Better understanding the mechanisms for the motility of cancer cells will benefit the treatment. Accumulating evidence suggests that aberrant microRNA (miRNA) expression contributes to HCC development and progression, whereas miR-3691-5p has not been reported in HCC. Purpose: The aim of this study was to elucidate the expression, function and mechanism of miR-3691-5p in HCC. Methods: Real-time quantitative polymerase chain reaction (qPCR) was performed to detect miR-3691-5p expression in HCC tissues and cell lines database analysis were conducted for detection of the expression of miR-3691-5p in HCC. Then, the association of miR-3691-5p with clinicopathological features of HCC patients were statistically measured. Subsequently, we attempted to observe the effects of miR-3691-5p on migration and invasion of HCC cells by transwell assays. Furthermore, bioinformatics tools and luciferase reporter gene assay as well as recuse experiments were conducted to explore the target of miR-3691-5p in HCC, and to explore whether the target mediated the effects of miR-3691-5p HCC cells. Results: In the current study, we found that miR-3691-5p expression was elevated in both HCC tissues and cell lines, which was significantly correlated with poor prognosis and clinicopathological features including TNM stage (P=0.016) and vascular invasion (P=0.016). Furthermore, gain-or loss-of function assays demonstrated that miR-3691-5p promoted HCC cell migration and invasion. Luciferase reporter assay confirmed that PTEN was a direct downstream target of miR-3691-5p. Recuse assays showed that restoration of PTEN reversed the effects of miR-3691-5p on HCC cell migration and invasion through decreasing PI3K/Akt signaling. Conclusion: Our results demonstrated that miR-3691-5p contributes to HCC cell migration and invasion through activating PI3K/Akt signaling by targeting PTEN.

Abstract
Cell division is a highly regulated and carefully orchestrated process. Understanding the mechanisms that promote proper cell division is an important step toward unraveling important questions in cell biology and human health. Early studies seeking to dissect the mechanisms of cell division used classical genetics approaches to identify genes involved in mitosis and deployed biochemical approaches to isolate and identify proteins critical for cell division. These studies underscored that post-translational modifications and cyclin-kinase complexes play roles at the heart of the cell division program. Modern approaches for examining the mechanisms of cell division, including the use of high-throughput methods to study the effects of RNAi, cDNA, and chemical libraries, have evolved to encompass a larger biological and chemical space. Here, we outline some of the classical studies that established a foundation for the field and provide an overview of recent approaches that have advanced the study of cell division.

Abstract
OBJECTIVES It has been accounted that miR-664a-3p has different functions in several malignancies; however, the precise role and underlying mechanism in gastric cancer have not been elucidated. Our study aims to explore the function of miR-664a-3p on the progression of gastric cancer (GC). METHODS qRT-PCR was applied to detect the expression of miR-664a-3p in GC tissues and cells. The functions of miR-664a-3p on GC in vitro were examined by cell proliferation assay, and transwell assay. Related proteins of epithelial-mesenchymal transition (EMT) and signal pathway were evaluated by Western blot and immunofluorescence analysis. The bioinformatic, dual-luciferase assay or ChIP assay were employed to identify the interaction between miR-664a-3p and its target gene or Foxp3. The effects in vivo were investigated through a mouse tumorigenicity model. RESULTS miR-664a-3p was frequently upregulated in GC tissues and cells. Elevated expression of miR-664a-3p significantly promoted proliferation and invasion in vitro and in vivo. MOB1A was confirmed to be a target of miR-664a-3p and restoration of MOB1A attenuated the effects of miR-664a-3p. A series of investigations indicated that miR-664a-3p contributed to EMT process and inactivated the Hippo pathway by downregulating MOB1A. CONCLUSION Taken together, we revealed that miR-664a-3p functions as an oncogene by targeting Hippo pathway in the development of gastric cancer.

Abstract
Ubiquitin-like with PHD and ring finger domains 1 (UHRF1) is abnormally overexpressed in multiple cancers and closely correlated with tumor-promoting effects, such as high proliferation. However, how UHRF1 functions in intrahepatic cholangiocarcinoma (ICC) has not yet been determined. Herein, we found that UHRF1 is overexpressed in ICC tissues. Downregulated UHRF1 attenuated the transition of the G1/S cell cycle and then suppressed cell proliferation in vitro and tumor growth in vivo. Moreover, upstream regulators of the UHRF1 expression were predicted, and we found that direct binding of miR-124-3p inhibited the UHRF1 expression. Elevated miR-124-3p suppressed proliferation and led to the arrest of the cell cycle. Furthermore, the expression of UHRF1 was positively correlated with PCNA. Clinically, we showed that elevated UHRF1 was associated with poor prognosis, and served as an independent prognostic factor in ICC patients. Together, these findings demonstrate that UHRF1, regulated by miR-124-3p, acts as a tumor promoter by promoting cell proliferation in ICC.

Shan S, Chen W, Jia JD. Transcriptome Analysis Revealed a Highly Connected Gene Module Associated With Cirrhosis to Hepatocellular Carcinoma Development. Front Genet 2019; 10:305. [PMID: 31001331 PMCID: PMC6454075 DOI: 10.3389/fgene.2019.00305] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2018] [Accepted: 03/19/2019] [Indexed: 12/27/2022] Open
Abstract
Introduction Cirrhosis is one of the most important risk factors for development of hepatocellular carcinoma (HCC). Recent studies have shown that removal or well control of the underlying cause could reduce but not eliminate the risk of HCC. Therefore, it is important to elucidate the molecular mechanisms that drive the progression of cirrhosis to HCC. Materials and Methods Microarray datasets incorporating cirrhosis and HCC subjects were identified from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were determined by GEO2R software. Functional enrichment analysis was performed by the clusterProfiler package in R. Liver carcinogenesis-related networks and modules were established using STRING database and MCODE plug-in, respectively, which were visualized with Cytoscape software. The ability of modular gene signatures to discriminate cirrhosis from HCC was assessed by hierarchical clustering, principal component analysis (PCA), and receiver operating characteristic (ROC) curve. Association of top modular genes and HCC grades or prognosis was analyzed with the UALCAN web-tool. Protein expression and distribution of top modular genes were analyzed using the Human Protein Atlas database. Results Four microarray datasets were retrieved from GEO database. Compared with cirrhotic livers, 125 upregulated and 252 downregulated genes in HCC tissues were found. These DEGs constituted a liver carcinogenesis-related network with 272 nodes and 2954 edges, with 65 nodes being highly connected and formed a liver carcinogenesis-related module. The modular genes were significantly involved in several KEGG pathways, such as “cell cycle,” “DNA replication,” “p53 signaling pathway,” “mismatch repair,” “base excision repair,” etc. These identified modular gene signatures could robustly discriminate cirrhosis from HCC in the validation dataset. In contrast, the expression pattern of the modular genes was consistent between cirrhotic and normal livers. The top modular genes TOP2A, CDC20, PRC1, CCNB2, and NUSAP1 were associated with HCC onset, progression, and prognosis, and exhibited higher expression in HCC compared with normal livers in the HPA database. Conclusion Our study revealed a highly connected module associated with liver carcinogenesis on a cirrhotic background, which may provide deeper understanding of the genetic alterations involved in the transition from cirrhosis to HCC, and offer valuable variables for screening and surveillance of HCC in high-risk patients with cirrhosis.

[PMID: 35116769 PMCID: PMC8798919 DOI: 10.21037/tcr.2019.01.38] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2018] [Accepted: 12/28/2018] [Indexed: 12/23/2022]
Abstract
Background Hsa_circ_0002124, which was first reported in 2013, is derived from NuSAP1. However, its role in hepatocellular carcinoma (HCC) and its regulatory mechanisms remain to be investigated. Methods First, hsa_circ_0002124 was structurally validated via specific convergent and divergent primer amplification. The hsa_circ_0002124 expression in the liver cancer tissues and multiple HCC cell lines were determined using qPCR. Further, the cell functions of hsa_circ_0002124 in HCC cells were examined using knockdown and overexpressed hsa_circ_0002124 in 97H cells. The cell proliferation was assessed using MTS assay, cell proliferation and invasion capacities were evaluated using Transwell culture system, and cell cycle progression and apoptosis were analyzed using flow cytometry. Further, GO and KEGG analyses were performed to uncover the key function and pathways in HCC. The interaction networks between hsa_circ_0002124 and its downstream miRNAs and genes were constructed using Cytoscape software. The key protein expressions (p-JNK, JNK, p-ERK, ERK, p-P38, P38, and c-Myc) of the MAPK pathway in 97H cells with knockdown and overexpressed hsa_circ_0002124 treatments were detected using Western blotting. Results Hsa_circ_0002124 was highly expressed in the HCC cells and liver cancer tissues. Moreover, the knockdown hsa_circ_0002124 in 97H cells resulted in the repression of cell proliferation, cell invasion, and migration, with simultaneous promotion of cell apoptosis and cell cycle transformation. The opposing situations of cell function could be detected in overexpressed hsa_circ_0002124 in 97H cells. KEGG and interaction network analysis of hsa_circ_0002124 indicated that hsa_circ_0002124 could be a molecular sponge of miRNAs, which regulates the key protein expressions in the MAPK pathway. The p-JNK/JNK, p-ERK/ERK, p-P38/P38, and c-Myc expressions in knockdown hsa_circ_0002124-treated 97H cells were significantly lower than in normal 97H cells, whereas these expressions in overexpressed hsa_circ_0002124-treated 97H cells were significantly higher than in mock vector-treated 97H cells. Conclusions Hsa_circ_0002124 could be a potential biomarker for the early diagnosis and treatment of HCC.

JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2019; 38:33. [PMID: 30678687 PMCID: PMC6346521 DOI: 10.1186/s13046-019-1037-y] [Citation(s) in RCA: 54] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/25/2018] [Accepted: 01/13/2019] [Indexed: 01/06/2023]
Abstract
Background The primary obstacle to treat cervical cancer is its high prevalence of metastasis, which severely affects patients’ quality of life and survival time. Nucleolar and spindle associated protein 1 (NUSAP1) has been implicated in the development, progression, and metastasis in several types of cancer. However, its oncogenic role in cervical cancer remains unclear. Methods Western blot assay and immunohistochemistry were used to determine the expression of NUSAP1 in 21 clinical fresh Cervical cancer tissues and 233 clinicopathologically characterized cervical cancer specimens. The biological roles of NUSAP1 in the metastasis of cervical cancer were investigated both in vitro by EMT, Side population analysis and Transwell assays and so on, and in vivo using a mouse 4w model of hematogenous metastasis and lymph node metastasis. Bioinformatics analysis, luciferase reporter analysis, immunoprecipitation and immunoblotting of nuclear and cytoplasmic cellular fractions were applied to discern and examine the relationshipbetween NUSAP1 and its potential targets. Results The results demonstrated that NUSAP1 was upregulated in cervical cancer cells and tissues, correlated positively with metastasis and poor clinical outcome of patients. High expression of NUSAP1 promoted metastasis by enhancing cancer stem cell (CSC) traits and epithelial-mesenchyme transition (EMT) progression, while silencing of NUSAP1 reduced CSC traits and EMT progression. Mechanistically, upregulation of NUSAP1 induced SUMOylation of TCF4 via interacting with SUMO E3 ligase Ran-binding protein 2 (RanBP2) and hyperactivated Wnt/β-catenin signaling in cervical cancer cells. Additionally, NUSAP1-induced cervical cancer cells metastasis and the cancer stem cell phenotype were abrogated with the Wnt/β-catenin signaling inhibitor XAV-939 treatment. Importantly, co-therapy of conventional treatment and XAV-939 will provide a novel and effective treatment for NUSAP1-ovexpressed cervical cancer patients. Conclusions Our results demonstrate thatNUSAP1 upregulation contributes to metastasis of cervical cancer by promoting CSC properties and EMT via Wnt/β-catenin signaling and XAV-939 might serve as a potential tailored therapeutic option for patients with NUSAP1-ovexpressed cervical cancer.
