Abstract
Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that the control GAPDH western blotting bands shown in Fig. 4H on p. 496 were strikingly similar to data that were submitted for publication in advance of this article in different form by different authors at different research institutes [Liu F, Bai C and Guo Z: The prognostic value of osteopontin in limited‑stage small cell lung cancer patients and its mechanism. Oncotarget 8: 70084‑70096, 2017]. A further independent investigation conducted in the Editorial Office revealed that other western blotting data were likely to have been shared in common, comparing between the two articles. Owing to the fact that the contentious data in the above article had already been submitted for publication prior to the submission of this article to Oncology Reports, the Editor has decided that this paper should be retracted from the Journal. After having been in contact with the authors, it was admitted that the authors Feng Chang, Jian-Na Liu and Jun-Xin Lin did not initially provide their agreement to be authors on this paper; otherwise, the rest of the authors accepted the decision to retract the paper. The Editor apologizes to the readership for any inconvenience caused. [Oncology Reports 39: 491‑500, 2018; DOI: 10.3892/or.2017.6142].

Abstract
Cholangiocarcinoma (CCA) is a highly invasive malignant tumor with high mortality. Most cases of CCA are already advanced when they are detected, resulting in poor prognosis. As such, there is an ongoing need for the identification of effective biomarkers for CCA. The long noncoding RNA DLGAP1-AS2 has been reported to have prognostic value in glioma and Wilms' tumor. Here, we investigated the function of DLGAP1-AS2 in CCA. The differential expression of DLGAP1-AS2 in CCA tissues and normal tissues was first examined using data from the The Cancer Genome Atlas database and then in CCA cell lines by quantitative RT-PCR (qRT-PCR). The target gene was predicted by bioinformatics analysis, and the binding sites were confirmed using luciferase assay. DLGAP1-AS2 is up-regulated in CCA, and high DLGAP1-AS2 expression promotes cell viability and is associated with poor prognosis. Notably, DLGAP1-AS2 acts as a sponge to suppress miR-505 expression, and miR-505 reduces the expression of N-acetylgalactosaminyltransferase 10 (GALNT10) in CCA cells. Biofunctional experiments revealed that a miR-505 inhibitor almost completely removed the inhibitory effect of si-DLGAP1-AS2 on CCA cell malignant progression, whereas the malignant phenotype of cells cotransfected with si-DLGAP1-AS2 and si-GALNT10 was significantly reduced as compared with the control. In summary, the DLGAP1-AS2/miR-505/GALNT10 axis may contribute to regulating the malignant progression of CCA and may have potential as a novel target for CCA therapy.

Abstract
Background: MicroRNAs (miRNAs) and long non-coding RNAs (lncRNAs) play vital regulatory roles in pancreatic cancer (PC) initiation and progression. We aimed to explore the biological functions and underlying mechanisms of miR-505-3p (miR-505) in PC. Methods: We first screened miRNA expression profiles using microarray in PC tissues and normal tissues, and then studied the function and underlying mechanism of miR-505. Moreover, we evaluated the regulatory effect of lncRNA LINC01448 on miR-505. Results: We demonstrated miR-505 that was significantly downregulated in PC tissues. We further revealed that miR-505 significantly inhibited cell proliferation, invasion, sphere formation, glucose consumption, and lactate production by targeting HK2. In addition, overexpression of miR-505 led to tumor growth inhibition in vivo, demonstrating that it acts as a tumor suppressor in PC. LINC01448 was identified as an oncogenic lncRNA that could reduce miR-505 expression. Subsequent studies confirmed that LINC01448 enhanced cell proliferation, invasion, sphere formation, glucose consumption, and lactate production by regulating the miR-505/HK2 pathway. Conclusions: These findings demonstrated that miR-505, suppressed by LINC01448, could function as a key tumor suppressor by targeting HK2 in PC, elucidating an important role of the LINC01448/miR-505/HK2 pathway in regulating PC glycolysis and progression.

Abstract
Aim: This study aimed to investigate the expression of microRNA-505 (miR-505) and explore its clinical significance, biological function and mechanisms in hepatocellular carcinoma (HCC). Methods: Expression of miR-505 was measured in 128 paired HCC tissues and five cell lines by quantitative real-time polymerase chain reaction (qRT-PCR). MTT assay, Transwell migration, invasion assays and apoptosis assay were performed to explore the functional role of miR-505. The target gene of miR-505 was assessed using the bioinformatics assay and the related signaling pathway was confirmed using western blot. Results: Expression of miR-505 in HCC serum and tissues were downregulated. The overexpression of miR-505 in HCC cells inhibited cell proliferation and metastasis, as well as enhanced cell apoptosis by directly downregulating heterogeneous nuclear ribonucleoprotein M (HNRNPM). The activity of the Wnt/β-catenin signaling pathway was suppressed by the overexpression of miR-505 but was promoted by the upregulation of HNRNPM. Conclusion: The results suggest that the regulation of miR-505/HNRNPM may be a novel strategy to improve the targeted therapy of HCC.

Abstract
Endometritis is characterized by severe inflammation and tissue damage. It is a common clinical disease that causes infertility due to infectious diseases of the reproductive system. MicroRNAs (miRNAs) are the current focus of research on the regulation of the inflammatory process and play a vital role in various inflammatory diseases. The highly conserved miR-505 regulates the mechanism of lipopolysaccharide (LPS) induced endometritis, but the extent to which pro-inflammatory genes are activated remains unclear. The results of this study showed that the expression of miR-505 was significantly down-regulated in mouse endometritis tissue and LPS-stimulated BEND cells. The study also showed that overexpression of miR-505 significantly suppressed the production of the pro-inflammatory cytokines IL-1β, IL-6 and TNF-α, and this effect was reversed by inhibiting the expression of miR-505. Moreover, miR-505 inhibited the expression of HMGB1 by targeting its 3'-UTR, thereby inhibiting the activation of HMGB1/NF-κB signalling. Taken together, the results of this study further confirmed that miR-505, as an anti-inflammatory agent, regulates the activation of the HMGB1/NF-κB signalling pathway through negative feedback.

Abstract
Long noncoding RNAs (lncRNAs) are crucial regulatory factors in the development and progression of human malignancies. The purpose of this study was to investigate the potential mechanism of ZEB1-AS1 in pancreatic cancer (PC). The expression of ZEB1-AS1 in PC tissues and cells was assessed by RT-qPCR. The overall survival rate was evaluated using the Kaplan-Meier analysis. The association between ZEB1-AS1 and miR-505 was verified by dual-luciferase reporter assay. CCK-8 assay was employed to analyze PC cell viability. Transwell assay was employed to detect the migration and invasion of PC cells. Our results revealed that ZEB1-AS1 expression was significantly upregulated in PC tissues and cells, and the high expression of ZEB1-AS1 indicated the low overall survival rate in PC patients. Loss-of-function and gain-of-function assays indicated that knockdown of ZEB1-AS1 inhibited the cell viability, migration and invasion of PC cells, while overexpression of ZEB1-AS1 promoted PC cell progression. Moreover, ZEB1-AS1 upregulated TRIB2 expression via sponging miR-505. Finally, rescue assays demonstrated that TRIB2 overexpression partially abrogated the inhibitory effect of ZEB1-AS1 knockdown on the viability, migration and invasion of PC cells. These results confirmed that ZEB1-AS1 promoted the tumorigenesis of PC through the miR-505/TRIB2 axis, which indicated that ZEB1-AS1 might function as a biomarker for PC treatment and provide a new therapeutic direction in PC.

Abstract
Osteosarcoma is a malignant bone tumor, and clinically detectable metastases can be detected in ~ 15–20% of patients when they seek medical advice; patients with metastatic disease have extremely poor prognosis. Here, we examined the involvement of the microRNA miR‐505 in osteosarcoma. Eighty‐four patients seeking treatment for osteosarcoma were included in the study group (SG), and 63 healthy subjects were allocated to the control group (CG). Normal human bone cells MG‐63 and U20S cells were transfected with miR‐505 mimics, miR‐NC, HMGB1 RNA for targeted inhibition (si‐HMGB1), and si‐NC to examine the effects on HMGB1 expression. Cell proliferation, invasion, and apoptosis were measured using CCK‐8, scratch assays, and flow cytometry (FCM), respectively, and the relationship between miR‐505 and HMGB1 was determined using the dual‐luciferase reporter assay. In patient tissues and serum, miR‐505 was expressed at a low level, and HMGB1 was expressed at a high level, with an area under curve of > 0.9. Furthermore, the expression of miR‐505 and HMGB1 in tissues had a positive association with that in the serum, whereas the expression of miR‐505 had a negative association with that of HMGB1 in tissues only. Overexpression of miR‐505 and silencing of HMGB1 suppressed the proliferation, migration, and invasion of osteosarcoma cells and increased the rate of apoptosis, whereas the co‐transfected miR‐505 mimics + si‐HMGB1 demonstrated a more significant inhibitory effect on the proliferation and invasion of osteosarcoma cells and a higher apoptosis rate. miR‐505 may inhibit the proliferation and invasion and promote apoptosis of osteosarcoma cells by targeting and suppressing HMGB1.

Abstract
Objective Evidence suggests that microRNAs (miRNAs) regulate the expression of genes involved in bone metabolism. This study aimed to investigate the role of miR-505 in the osteogenic differentiation of MC3T3-E1 cells. Methods We performed miRNA sequencing to identify differentially expressed miRNAs between MC3T3-E1 cells treated with osteogenic induction medium (OIM) and control cells. Bioinformatics analysis was performed by using the TargetScan and miRDB databases. The expression of miR-505 in MC3T3-E1 cells was detected during osteogenic differentiation. After transfection with miR-505 mimic or miR-505 inhibitor, MC3T3-E1 cells were induced to differentiate into osteoblasts, and the expression of osteogenic differentiation markers (Runt-related transcription factor 2 (RUNX2), alkaline phosphatase (ALP), osteopontin (OPN), osteocalcin (OCN), and osterix (OSX)) was detected. Results miR-505 was the most downregulated miRNA among the differentially expressed miRNAs. The RUNX2 gene was identified as a potential target of miR-505 using the target prediction program. miR-505 expression was downregulated during osteogenic differentiation of MC3T3-E1 cells. The expression of osteogenic marker genes was inhibited in MC3T3-E1 cells after transfection with miR-505. However, the expression of osteogenic marker genes was upregulated after transfection with miR-505 inhibitor. Conclusion This study is the first to report miR-505 could bind to the RUNX2 gene and thus regulate partly the dysfunction of osteoblasts differentiation, which is expected to be targets for the treatment of osteoporosis.

Abstract
Neutrophil extracellular traps (NETs) play an important role in the pathological process of atherosclerosis (AS). This study aims to evaluate whether exosomes from oxidized low-density lipoprotein (ox-LDL)-treated vascular endothelial cells (VECs) aggravate AS by inducing NET formation. Exosomes from the peripheral blood of healthy donors and AS patients (namely NC-EXO and AS-EXO, respectively) and exosomes from human umbilical vein endothelial cells (HUVECs) treated without or with ox-LDL (namely normal EXO and ox-LDL-EXO, respectively) were isolated, identified, and co-cultured with neutrophils from peripheral blood of healthy donors. NET formation was evaluated by immunofluorescence staining and determining the content of cell-free DNA and myeloperoxidase-DNA complex. Dual-luciferase reporter assay, chromatin immunoprecipitation assay, quantitative reverse transcription polymerase chain reaction, and western blot analysis were performed to explore the underlying mechanisms. We found that AS-EXO and ox-LDL-EXO induced NET release from neutrophils. Mechanistically, ox-LDL treatment in HUVECs might activate the NF-κB pathway, which transcriptionally activates miR-505, and then the exosome-encapsulated high miR-505 expression targeted and inhibited SIRT3 in neutrophils, thereby inducing reactive oxygen species (ROS) level increase and NET release by neutrophils. Further in vivo experiments showed that ox-LDL-EXO accelerated AS progression in AS mice. In summary, exosome-encapsulated miR-505 from ox-LDL-treated VECs aggravates AS by inducing NET formation.

Abstract
We explored the roles and regulatory mechanisms of the circular RNA (circRNA) nuclear receptor-interacting protein 1 (NRIP1; circNRIP1) in ACHN and CAKI-1 cells. ACHN and CAKI-1 cells were transfected with small-interfering-circNRIP1 (si-circNRIP1) and microRNA-505 (miR-505) inhibitor or the corresponding controls. Cell viability was detected with the Cell Counting Kit-8. The protein expression levels of Bcl-2, Bax, cleaved-caspase-3, matrix metalloproteinase (MMP)-2, MMP-9, adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK), protein kinase B (AKT), phosphatidylinositol 3-kinase (PI3K), and mammalian target of rapamycin (mTOR) were individually determined via Western blot. Quantitative reverse transcription polymerase chain reaction was used to examine the expressions of circNRIP1 and miR-505 both in tumor cells and tissues. The apoptotic rate, the colony numbers, and the migration rate were separately determined by the Annexin V-fluorescein isothiocyanate/propidium iodide and flow cytometer, colony formation assay, and migration assay. We found that circNRIP1 was overexpressed in tumor tissue but miR-505 was overproduced. Silencing circZNF292 induced inhibition of cell viability, colony formation, and migration, as well as the activity of AMPK and PI3K/AKT/mTOR cascades but enhancement of apoptosis. si-circNRIP1 stimulated the upregulation of miR-505, whose silence abolished the effects of si-circNRIP1 on these elements mentioned above. In conclusion, the circNRIP1 played oncogenic roles in the ACHN and the CAKI-1 cell lines by targeting miR-505 via stimulating AMPK and PI3K/AKT/mTOR cascades.

Abstract
Background This study aimed to investigate the regulatory role of long non-coding RNA associated with microvascular invasion in hepatocellular carcinoma (lnc-MVIH) in the progression of acute myeloid leukemia (AML) and the underlying mechanism. Methods Lnc-MVIH expression was detected in AML cell lines AML-193, KG-1, HL-60, OCI-AML2 and primary normal bone marrow mononuclear cells (BMMC). The effect of lnc-MVIH knockdown on cell proliferation, apoptosis and miR-505 expression were detected by transfection of lnc-MVIH shRNA and control shRNA into KG-1 cells. And the effect of miR-505 knockdown on lnc-MVIH, cell proliferation, cell apoptosis as well as potential miR-505 target genes [high mobility group box 1 (HMGB1) and cyclin E2 (CCNE2)] in lnc-MVIH knockdown treated KG-1 cells was assessed by transfection of lnc-MVIH shRNA and lnc-MVIH shRNA & miR-505 shRNA into KG-1 cells. Results Lnc-MVIH expression was elevated in AML-193, KG-1, OCI-AML2 cell lines, but similar in HL-60 cell line compared with primary normal BMMC. Lnc-MVIH knockdown inhibited cell proliferation but promoted cell apoptosis in KG-1 cells, meanwhile miR-505 expression was increased by lnc-MVIH knockdown in KG-1 cells. And in rescue experiments, miR-505 knockdown had no effect on expression of lnc-MVIH, while it increased the expressions of HMGB1 and CCNE2, promoted cell proliferation, inhibited cell apoptosis in lnc-MVIH knockdown treated KG-1 cells. Conclusions Lnc-MVIH knockdown inhibits cell proliferation but promotes cell apoptosis via regulating miR-505 mediated HMGB1 and CCNE2 in AML.

Abstract
We aimed to analyse the relative abundance of miR-505 in age-related macular degeneration (AMD) and elucidate its underlying mechanisms. Relative expression of miR-505 was analysed by real-time polymerase chain reaction (PCR). Macrophage polarization was characterized by measurement of molecular markers including Ym-1, Arg-1, TNF-α and iNOS via both real-time PCR and Western blot. Vascular endothelial growth factor (VEGF) content was determined by enzyme-linked immunosorbent assay. Choroidal neovascularization (CNV) formation was evaluated by choroidal flat mount technique. The regulatory action of miR-505-5p on 3'UTR of Transmembrane Protein 229B (TMEM229B) was interrogated by luciferase reporter assay. miR-505 was aberrantly upregulated in both AMD and laser-induced choroidal neovascularization mouse model. Administration with miR-505 specific inhibitor suppressed M2 polarization in CNV mice as indicated by decreasing both Ym-1 and Arg-1. Meanwhile, VEGF expression and CNV formation were greatly suppressed by miR-505 inhibition as well. The similar phenotype was consolidated in Prostaglandin E2 (PGE2)-stimulated bone marrow-derived macrophages. At the molecular level, miR-505-5p directly targeted and negatively regulated TMEM229B expression, while forced ectopic expression of TMEM229B significantly rescued miR-505-imposed M2 polarization. Our data have uncovered the critical contribution of miR-505 in AMD, which is predominantly mediated by downregulation of TMEM229B.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancers globally. An increasing body of evidence has demonstrated the critical function of microRNAs (miRNAs) in the initiation and progression of human cancers. Here, we showed that miR-505 was down-regulated in HCC tissues and cell lines. Reduced expression of miR-505 was significantly correlated with the worse prognosis of HCC patients. Overexpression of miR-505 suppressed the proliferation, colony formation and induced apoptosis of both HepG2 and Huh7 cells. Further mechanism study uncovered that miR-505 bound the 3'-untranslated region (3'-UTR) of the insulin growth factor receptor (IGF-1R) and inhibited the expression of IGF-1R in HCC cells. The down-regulation of IGF-1R by miR-505 further suppressed the phosphorylation of AKT at the amino acid S473. Consistently, the abundance of glucose transporter (GLUT) 1 (GLUT1) was reduced with the overexpression of miR-505. Down-regulation of GLUT1 by miR-505 consequently attenuated the glucose uptake, lactate production and ATP generation of HCC cells. Collectively, our results demonstrated the tumor suppressive function of miR-505 possibly via inhibiting the glycolysis of HCC cells. These findings suggested miR-505 as an interesting target for designing anti-cancer strategy in HCC.

Abstract
Gastric cancer (GC) is a frequent type of malignant tumor worldwide. GC metastasis results in the majority of clinical treatment failures. MicroRNAs (miRNA) are identified to exhibit crucial roles in GC. Our current study aimed to explore the biological roles of miR-505 in GC progression. It was observed that miR-505 was robustly decreased in GC cells compared with human normal gastric epithelial GES-1 cells. Overexpression of miR-505 was able to repress GC progression in AGS and BGC-823 cells. In addition, high-mobility group box 1 (HMGB1) has been identified as a crucial oncogene in several cancer types. By carrying out bioinformatics analysis, HMGB1 was predicted as a direct target of miR-505. Meanwhile, HMGB1 was found to be significantly increased in GC cells and it was confirmed in our study that miR-505 can directly target HMGB1 in vitro. miR-505 mimics can inhibit HMGB1 messenger RNA and protein expression dramatically. Subsequently, knockdown of HMGB1 can inhibit GC cell proliferation, colony formation, and induce cell apoptosis. Furthermore, HMGB1 silence suppressed GC cell migration and invasion greatly in vitro. Finally, it was validated that miR-505 can inhibit GC progression by targeting HMGB1 in vivo. Taken these together, it was indicated that miR-505/HMGB1 axis was involved in the development of GC. miR-505 can serve as a potential prognostic indicator in GC therapy.

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that regulate gene expression at the post-transcriptional level. Compelling evidence shows that there are causative links between miRNAs abnormal regulation and the development of cancer. miR-505 has been reported to be aberrant expression and functions as a tumor suppressor in many human cancers, but its roles and potential molecular mechanism in glioma remain unclear. Here, we found that the expression levels of miR-505 were down-regulated in glioma tissues and cell lines. Exogenous over-expression of miR-505 resulted in inhibited cell proliferation and invasion in glioma in vitro. Furthermore, dual luciferase reporter assay and western blot analysis confirmed that IGF1R (Insulin like growth factor 1 receptor) was a direct target gene of miR-505 in glioma. More importantly, over-expression of IGF1R rescued miR-505-mediated inhibition of cell proliferation and invasion in glioma in vitro. Taken together, our results suggest that miR-505 acts as a tumor suppressor in glioma via direct negative regulation of IGF1R, which may provide a novel therapeutic strategy.

Abstract
Compelling evidence has suggested the relevance of miRNAs in resistance to chemotherapeutic agents in HCC. miR-505 was reported to be downregulated and function as a tumor suppressor in HCC cells by binding to high-mobility group box 1 (HMGB1). Whether miR-505/HMGB1 axis was involved in ADM cytotoxicity in HCC remains to be addressed. The aim of this study was to explore the effect of miR-505/HMGB1 axis on ADM cytotoxicity in HCC cells. MTT, flow cytometry analysis, and caspase-3 activity assays were conducted to assess ADM-induced cytotoxicity. The protein level of phosphorylation of histone H2 AX at Ser139 (γH2AX) was detected to evaluate DNA damage. The effects of miR-505 and HMGB1 on the protein kinase B (Akt) pathway were determined by examining the protein levels of phosphorylated Akt (p-Akt), Akt, phosphorylated glycogen synthase kinase-3β (p-GSK-3β), and GSK-3β. We found that HMGB1 knockdown and miR-505 overexpression exacerbated ADM-induced cell viability inhibition, enhanced ADM-induced apoptosis, and increased caspase-3 activity in ADM-treated HCC cells. However, HMGB1 overexpression reversed the effects of miR-505 on ADM-induced cytotoxicity in HCC cells. HMGB1 knockdown and miR-505 overexpression promoted ADM-induced DNA damage in HCC cells, which was abated by HMGB1 overexpression. On a molecular mechanism level, HMGB1 silencing and miR-505 overexpression inactivated the Akt pathway in HCC cells, while exogenous HMGB1 resisted miR-505-induced Akt pathway inactivation. In conclusion, miR-505 overexpression enhanced ADM-induced cytotoxicity in HCC cells, at least partly by targeting HMGB1 and inactivating the Akt pathway.

Abstract
BACKGROUND Noninvasive biomarkers are urgently needed for patients with nonalcoholic steatohepatitis (NASH) to assist in diagnosis, monitoring disease progression and assessing treatment response. Recently several exploratory studies showed that circulating level of microRNA is associated with NASH and correlated with disease severity. Although these data were encouraging, the application of circulating microRNA as biomarkers for patient screening and stratification need to be further assessed under well-controlled conditions. RESULTS The expression of circulating microRNAs were profiled in diet-induced NASH progression and regression models to assess the diagnostic and prognostic values and the translatability between preclinical mouse model and men. Since these mice had same genetic background and were housed in the same conditions, there were minimal confounding factors. Histopathological lesions were analyzed at distinct disease progression stages along with microRNA measurement which allows longitudinal assessment of microRNA as NASH biomarkers. Next, differentially expressed microRNAs were identified and validated in an independent cohorts of animals. Thirdly, these microRNAs were examined in a NASH regression model to assess whether they would respond to NASH treatment. MicroRNA profiling in two independent cohorts of animals validated the up-regulation of 6 microRNAs (miR-122, miR-192, miR-21, miR-29a, miR-34a and miR-505) in NASH mice, which was designated as the circulating microRNA signature for NASH. The microRNA signature could accurately distinguish NASH mice from lean mice, and it responded to chow diet treatment in a NASH regression model. To further improve the performance of microRNA-based biomarker, a new composite biomarker was proposed, which consists of miR-192, miR-21, miR-505 and ALT. The new composite biomarker outperformed the microRNA signature in predicting NASH mice which had NAS > 3, and deserves further validations in large scale studies. CONCLUSION The present study supported the translation of circulating microRNAs between preclinical models and humans in NASH pathogenesis and progression. The microRNA-based composite biomarker may be used for non-invasive diagnosis, clinical monitoring and assessing treatment response for NASH.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression post-transcriptionally and play critical roles in intricate networks of host-pathogen interactions and innate immunity. Porcine reproductive and respiratory syndrome (PRRS) is one of the most important diseases affecting swine industry worldwide. Here, we demonstrated that miR-23, miR-378, and miR-505 were antiviral host factors against PRRS virus (PRRSV). Over-expression of the three miRNAs inhibited PRRSV infection in a dose-dependent manner, respectively. Blockage of the three endogenously expressed miRNAs significantly enhanced PRRSV replication. Different type 2 PRRSV strains harbored conserved miR-23, miR-378, and miR-505 target sites (TSs) that were sufficient to confer miRNA-mediated repression of PRRSV replication. Interestingly, miR-23 was capable of inducing type I interferon expression during PRRSV infection through IRF3/IRF7 activation, which might further lead to the inhibition of virus infection. These results suggest that miR-23, miR-378, and miR-505, especially miR-23, may have the potential to be used as antiviral therapy against PRRSV infection.
