Abstract
This study aimed to explore gene expression profiles that drive malignancy from low- to high-grade head and neck carcinomas (HNC), as well as to analyze their correlations with survival. Gene expressions and clinical data of HNC were downloaded from the Gene Expression Omnibus (GEO) repository. The significantly differential genes (SDGs) between low- and high-grade HNC were screened. Cox regressions were performed to identify prognostic SDGs of progression-free survival (PFS) and disease-specific survival (DSS). The genes were experimentally validated by RT-PCR in clinical tissue specimens. Thirty-five SDGs were identified in 47 low-grade and 30 high-grade HNC samples. Cox regression analyses showed that CXCL14, SLC44A1, and UBD were significantly associated with DSS, and PPP2R2C and SLC44A1 were associated with PFS. Patients were grouped into high-risk or low-risk groups for prognosis based on gene signatures. High-risk patients had significantly shorter DSS and PFS than low-risk patients (P=0.033 and P=0.010, respectively). Multivariate Cox regression showed HPV (P=0.033), lymph node status (P=0.032), and residual status (P<0.044) were independent risk factors for PFS. ROC curves showed the risk score had better efficacy to predict survival both for DSS and PFS (AUC=0.858 and AUC=0.901, respectively). The results showed CXCL14 and SLC44A1 were significantly overexpressed in the low-grade HNC tissues and the UBD were overexpressed in the high-grade HNC tissues. Our results suggested that SDGs had different expression profiles between the low-grade and high-grade HNC, and these genes may serve as prognostic biomarkers to predict survival.

Abstract
Nasopharyngeal carcinoma (NPC), which is associated with latent Epstein-Barr virus infection in most cases, is a unique epithelial malignancy arising from the nasopharyngeal mucosal lining. Accumulating evidence provides insights into the genetic and molecular aberrations that likely drive nasopharyngeal tumor development and progression. We review recent analyses of microRNAs (miRNAs), including Epstein-Barr virus-encoded miRNAs (EBV-encoded miRNAs) and dysregulated cellular miRNAs, that may be related to the metastasis of nasopharyngeal carcinoma. The studies summarized herein have greatly expanded our knowledge of the molecular biology of NPC involving miRNAs, and they may provide new biological targets for clinical diagnosis and reveal the potential of microRNA therapeutics. However, much information remains to be uncovered.

Abstract
MicroRNAs (miRNAs) play essential roles in regulating bone formation and homeostasis. Genomic variations within miRNA target sites may therefore be important sources of genetic differences in osteoporosis risk. The function of CCDC170 in bone biology is still unclear. To verify the function of CCDC170, we knocked down CCDC170 in cells and mice and searched for miRNA recognition sites within CCDC170 using the TargetScan, miRNASNP, and miRBase databases. In this study, our results demonstrated that CCDC170 plays an important role in the positive regulation of bone formation. MiR-153-3p, miR-374b-3p, miR-4274, miR-572 and miR-2964a-5p inhibited CCDC170 expression in an allele-specific manner by binding GWAS lead SNPs rs6932603, rs3757322 and rs3734806. These findings may improve our understanding of the association between CCDC170, miRNAs, GWAS lead SNPs, and osteoporosis pathogenesis and may provide a potential therapeutic target for osteoporosis therapy. Summary: CCDC170 may provide a potential therapeutic target for osteoporosis therapy.

The long non-coding RNA GHSROS reprograms prostate cancer cell lines toward a more aggressive phenotype. PeerJ 2021; 9:e10280. [PMID: 33585078 PMCID: PMC7860111 DOI: 10.7717/peerj.10280] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2019] [Accepted: 10/09/2020] [Indexed: 12/27/2022] Open
Abstract
It is now appreciated that long non-coding RNAs (lncRNAs) are important players in orchestrating cancer progression. In this study we characterized GHSROS, a human lncRNA gene on the opposite DNA strand (antisense) to the ghrelin receptor gene, in prostate cancer. The lncRNA was upregulated by prostate tumors from different clinical datasets. Transcriptome data revealed that GHSROS alters the expression of cancer-associated genes. Functional analyses in vitro showed that GHSROS mediates tumor growth, migration and survival, and resistance to the cytotoxic drug docetaxel. Increased cellular proliferation of GHSROS-overexpressing PC3, DU145, and LNCaP prostate cancer cell lines in vitro was recapitulated in a subcutaneous xenograft model. Conversely, in vitro antisense oligonucleotide inhibition of the lncRNA reciprocally regulated cell growth and migration, and gene expression. Notably, GHSROS modulates the expression of PPP2R2C, the loss of which may drive androgen receptor pathway-independent prostate tumor progression in a subset of prostate cancers. Collectively, our findings suggest that GHSROS can reprogram prostate cancer cells toward a more aggressive phenotype and that this lncRNA may represent a potential therapeutic target.

Abstract
Human males absent on the first (hMOF) is a histone acetyltransferase (HAT) and is involved in the pathogenesis of various cancers. This article aimed to reveal the potential mechanism of the miR-572/hMOF/Sirt6 axis in ovarian cancer (OC). In this study, we found that the mRNA and protein levels of hMOF and Sirt6 were abnormally down-regulated in OC tissues and cells. Further study indicated that the overexpression of hMOF increased the level of H4 histone acetylation in the Sirt6 promoter region and enhanced the ability of hMOF to bind to the Sirt6 promoter in OC cells, and repressed the proliferation of SKOV3 cells and promoted the apoptosis of SKOV3 cells via up-regulating Sirt6. Moreover, it was found that miR-572 negatively regulated hMOF luciferase activity. After the transfection of miR-572 inhibitor into SKOV3 cells, the cell proliferation was significantly repressed, while this repression was reversed after the transfection of shRNA-hMOF. Besides, the overexpression of hMOF could significantly inhibit the growth of tumors. Overall, our findings uncovered a novel regulatory pattern of hMOF in OC progression and provided new insights for relieving OC.

Curr Mol Pharmacol 2020; 12:324-333. [PMID: 31677258 DOI: 10.2174/1874467212666190719120446] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2019] [Revised: 05/27/2019] [Accepted: 06/18/2019] [Indexed: 12/25/2022]
Abstract
AIMS The aim is to study the role of miR-675-5p coded by long non-coding RNA H19 in the development of Nasopharyngeal Cancer (NPC) and whether miR-675-5p regulates the invasion and metastasis of NPC through targeting SFN (14-3-3σ). The study further validated the relationship between H19, miR-675-5p and SFN in NPC and their relationship with the invasion and metastasis of NPC. METHODS Western blot was used to detect the expression of 14-3-3σ protein in immortalized normal nasopharyngeal epithelial cells NP69 and different metastatic potential NPC cells, 6-10B and 5-8F. At the same time, to find out the relationship between 14-3-3σ protein and the expression of H19 and miR-675-5p, the expression of H19 and miR-675-5p in normal nasopharynx epithelial cells NP69 and varied nasopharyngeal carcinoma cells 6-10B and 5-8F were quantified by real-time PCR. MiR-675-5p mimic and inhibitor were transfected into NPC 6-10B to over-express and down-express miR-675-5p; miR-675-5p mimic negative control and inhibitor negative control were transfected into NPC 6-10B as control groups. The effect of over-expression and down-expression by miR-675-5p on the expression of 14-3-3σ protein was detected by Western blotting. The 3'-UTR segments of SFN, containing miR-675-5p binding sites were amplified by PCR and the luciferase activity in the transfected cells was assayed to detect whether SFN is the direct target of miR-675-5p. Transwell and scratch assays were used to verify the changes in NPC invasion and metastasis ability of mimics and inhibitors transfected with miR-675-5p. RESULTS The expression of 14-3-3σ protein in normal nasopharynx epithelial cells NP69 is significantly higher than in varied nasopharyngeal carcinoma cells, 6-10B and 5-8F (P<0.05), and the 14-3-3σ protein levels in low-metastatic nasopharyngeal carcinoma cell 6-10B is higher than in high-metastatic nasopharyngeal carcinoma cell 5-8F. The expression of H19 and miR-675-5p are significantly higher in NPC cells than in NP69 cell (P<0.05). The expression of H19 and miR-675-5p in high-Metastatic nasopharyngeal carcinoma cell 5-8F was higher than in low-Metastatic nasopharyngeal carcinoma cell 6-10B. The expression of 14-3-3σ protein in miR-675-5p mimic cells was significantly lower than in mimic NC (negative control) group and blank control group. However, compared with the blank control group, mimic NC showed no significant difference in 14-3-3σ protein between the two groups. The miR-675-5p inhibitor group was significantly higher than the inhibitor NC group and the blank control group (p<0.05), but there was no significant difference in the expression of 14-3-3σ protein in the inhibitor NC group and the blank control group (p>0.05). Dual-luciferase reporter assay system shows the 3'-UTR segments of SFN containing miR-675-5p binding sites. SFN was the target gene of miR-675-5p. CONCLUSION 14-3-3σ is downregulated in NPC and is involved in the development of NPC. H19 and miR- 675-5p are upregulated in NPC, which is related to the development of NPC. The over-expression of miR- 675-5p inhibits the expression of 14-3-3σ protein. SFN is the target gene of miR-675-5p. MiR-675-5p targets SFN, downregulates its protein expression and promotes the invasion and metastasis of NPC.

Abstract
Background Recent studies indicate amorphous silica nanoparticles (SiNPs), one of the widely applied nanomaterials, have potential toxicity in humans and induces cell malignant transformation. However, its carcinogenic mechanisms remain poorly understood. This study’s purpose was to investigate the underlying toxic mechanisms of amorphous SiNPs on human lung epithelial cells model by using microarray data. Methods Microarray dataset GSE82062 was collected from Gene Expression Omnibus database, including three repeats of Beas-2B exposed to amorphous SiNPs for 40 passages and three repeats of passage-matched control Beas-2B cells. Differentially expressed genes (DEGs) were identified using linear models for microarray data method. Protein–protein interaction (PPI) network was constructed using data from the STRING database followed by module analysis. The miRwalk2 database was used to predict the underlying target genes of differentially miRNAs. Function enrichment analysis was performed using the Database for Annotation, Visualization and Integrated Discovery (DAVID) online tool. Results A total of 323 genes were identified as DEGs, including 280 downregulated (containing 12 pre-miRNAs) and 43 upregulated genes (containing 29 pre-miRNAs). Function enrichment indicated these genes were involved in translational initiation (i.e., eukaryotic translation initiation factor 4 gamma 2 (EIF4G2), poly (A) binding protein cytoplasmic 1 (PABPC1)), response to reactive oxygen species (i.e., superoxide dismutase 1 (SOD1)) and oxidative phosphorylation (i.e., ATP5H). PABPC1 (degree = 15), ATP5H (degree = 11) and SOD1 (degree = 8)] were proved to be hub genes after PPI-module analyses. ATP5H/SOD1 and EIF4G2/PABPC1 were overlapped with the target genes of differentially expressed pre-miR-3648/572/661 and pre-miR-4521. Conclusions Amorphous SiNPs may induce tumorigenesis via influencing ATP5H/SOD1-related oxidative stress, oxidative phosphorylation and EIF4G2/PABPC1-associated translational initiation which may be regulated by miR-3648/572/661 and miR-4521, respectively.

Diagnostic Value of Circulating microRNAs for In-Stent Restenosis in Patients with Lower Extremity Arterial Occlusive Disease. Sci Rep 2019; 9:1402.

Abstract
In-stent restenosis (ISR) is still a major cause of failure of endovascular stenting treatment in patients with lower extremity arterial occlusive disease (LEAOD). Sensitive and reliable biomarkers for early diagnosis to predict ISR should be considered. This study was conducted to explore the diagnostic value of microRNA in predicting ISR in patients with LEAOD after endovascular stenting treatment. From March 2014 to July 2016, 208 patients (170 males and 38 females) with LEAOD undergoing interventional treatment were enrolled in this research. Patients were divided into the restenosis and non-restenosis groups according to routine postoperative angiography. Circulating microRNAs expression were detected in 208 participants, including 78 ISR patients, 68 non-ISR patients and 62 healthy volunteers. We selected 6 microRNAs from microarray screening as candidates for further testing via qRT-PCR. A receiver operating characteristic (ROC) curve was generated to assess the diagnostic value of circulating microRNAs in predicting ISR for LEAOD patients. The results showed that circulating microRNA-320a and microRNA-572 in patients with ISR (n = 78) had significantly higher expression levels than it from non-ISR and healthy volunteers. By receiver operating characteristic curve analysis, the sensitivity was 82.1% and the specificity was 63.8% for microRNA-320a; the sensitivity was 69.2% and the specificity was 68.9% for microRNA-572, and the AUC was 0.766 and 0.690 for detection of ISR, respectively. Furthermore, 78 patients with ISR had significantly higher circulating expression levels of microRNA-3937 and microRNA-642a-3p and lower circulating expression levels of microRNA-4669 and microRNA-3138 compared with 68 non-ISR patients and 62 healthy volunteers, but they have no significant difference. We found that differential circulating microRNA expression in patients after stenting with ISR, and the data indicate that circulating microRNA-320a and microRNA-572 have promising value in diagnosing ISR in patients with LEAOD.

Abstract
Emerging evidence have discovered that circular RNAs (circRNAs) may serve as diagnostic or tumor promising biomarkers. This study aimed to investigate how circular RNA ADAMTS14 (circADAMTS14) regulates microRNA-572/ regulator of calcineurin 1(miR-572/ RCAN1) in hepatocellular carcinoma (HCC). The expression profiles of circRNA/microRNA (mRNA) between HCC tissues and paired adjacent tissues were analyzed via microarray analysis. The expressions of circADAMTS14, miR-572, and RCAN1 were measured by real-time polymerase chain reaction (PCR). The protein expression level of RCAN1 in HCC cells was detected by western blot. The viability and apoptosis levels of HCC cell lines were measured by the cell counting Kit-8 (CCK-8) assay and fluorescence-activated cell sorter. The invasiveness and migration of cells were detected based on the transwell and wound-healing assay, respectively. The dual-luciferase reporter assays were used to reveal circADAMTS14 and RCAN1 as a potential target of miR-572, which was predicted by TargetScan and miRBase. The effect of circADAMTS14 on HCC cells was demonstrated by tumor formation in nude mice in vivo. CircADAMTS14 and RCAN1 were lowly expressed in HCC clinical specimens and cell lines using microarrays and qRT-PCR, but miR-572 inversely. Our study further verified the direct interaction between circADAMTS14 and RCAN1 with miR-572 via the dual-luciferase reporter gene assay. Overexpressed circADAMTS14 and RCAN1 induced apoptosis of HCC cells and inhibited cell proliferation and invasion. But overexpressed miR-572 could decrease apoptosis of HCC cells and promote proliferation and invasion. In vivo, circADAMTS14 inhibited the tumor growth, correlated positively with the protein expression levels of RCAN1. Our results demonstrated that circADAMTS14 might suppress HCC progression through regulating miR-572/ RCAN1 as the competing endogenous RNA.

Abstract
Purpose Colorectal carcinoma (CRC) is among the most common causes of death. Recent studies have shown that both STAT3 and miR-572 contribute to CRC progression. STAT3 plays an important role in miRNA expression. Moreover, MOAP-1, which is a pro-apoptotic protein that induces cell death or apoptosis, has a direct correlation with miRNA. Therefore, the current study is designed to explore whether miR-572 and STAT3 are involved in a common pathway and the role of MOAP-1 in this process. Patients and methods The expressions of STAT3, miR-572, and MOAP-1 in human CRC tissues and multiple cell lines were estimated by qRT-PCR or Western blot. MTT, transwell migration, and invasion assays were used to assess cell growth, migration, and invasion, respectively. Dual-luciferase reporter assay was applied to examine the association between miR-572 and MOAP-1. Results Elevated STAT3 levels were accompanied by increased miR-572 and decreased MOAP-1 levels in primary CRC specimens and cell lines. STAT3 promoted CRC cell growth, migration, and invasion via the upregulated expression of miR-572. Subsequently, miR-572 inhibited MOAP-1 protein expression through an interaction with its 3′UTR. Conclusion Our study proposes a novel STAT3-miR-572-MOAP-1 pathway involved in the process of CRC progression, which might be a potential target for the development of new preventive and therapeutic approaches against human colorectal cancer.
