Abstract
Breast carcinoma is a heterogeneous disease that affects millions of women worldwide. Wilms' tumor 1 (WT1) is an oncogene that promotes proliferation, metastasis and reduces apoptosis. MicroRNAs (miR) are short noncoding RNAs with a major role in cancer metastasis. In present study, we investigated the association of serum level of WT1 with oxidative stress and expression of miR-361-5p in breast cancer. Serum samples of 45 patients and of 45 healthy women analyzed for protein level of WT1, malondialdehyde (MDA), total oxidant status (TOS), and total antioxidant capacity (TAC). Serum and tissue expression of miR-361-5p in 45 tumor tissues and 45 paired non-tumor adjacent tissues and 45 serum samples of patients and healthy women analyzed by qRT-PCR. Protein levels of WT1 not significantly difference in serum of patients compared to healthy controls. Serum levels of MDA and TOS in patients were higher, but TAC level was lower than healthy controls (p < 0.001). There was a positive correlation between WT1 with MDA and TOS, and a negative correlation between WT1 with TAC in patients. miR-361-5p expression in tumor tissues and serum of patients was lower than non-tumor adjacent tissues and serum of healthy controls, respectively (p < 0.001). Moreover, there was a negative correlation between miR-361-5p and WT1 in patients. The positive correlation between WT1 with MDA and TOS and negative correlation between TAC and miR-361-5p suggests that this gene can play an important role in worse prognoses in breast cancer. Additionally, miR-361-5p may serve as an invasive biomarker for early detection of breast cancer.

Abstract
Senescent cells are key regulators of ageing and age-associated disease. MicroRNAs (miRs) are a key component of the molecular machinery governing cellular senescence, with several known to regulate important genes associated with this process. We sought to identify miRs associated with both senescence and reversal by pinpointing those showing opposing directionality of effect in senescence and in response to senotherapy. Cellular senescence phenotypes were assessed in primary human endothelial cells following targeted manipulation of emergent miRNAs. Finally, the effect of conserved target gene knockdown on lifespan and healthspan was assessed in a C. elegans system in vivo. Three miRNAs (miR-5787, miR-3665 and miR-361-5p) demonstrated associations with both senescence and rejuvenation, but miR-361-5p alone demonstrated opposing effects in senescence and rescue. Treatment of late passage human endothelial cells with a miR-361-5p mimic caused a 14 % decrease in the senescent load of the culture. RNAi gene knockdown of conserved miR-361-5p target genes in a C. elegans model however resulted in adverse effects on healthspan and/or lifespan. Although miR-361-5p may attenuate aspects of the senescence phenotype in human primary endothelial cells, many of its validated target genes also play essential roles in the regulation or formation of the cytoskeletal network, or its interaction with the extracellular matrix. These processes are essential for cell survival and cell function. Targeting miR-361-5p alone may not represent a promising target for future senotherapy; more sophisticated approaches to attenuate its interaction with specific targets without roles in essential cell processes would be required.

Abstract
BACKGROUND COX10-AS1 belongs to the class of lncRNA and has been shown to influence carcinogenesis; however, its function and underlying mechanism in oral squamous cell carcinoma are still unclear (OSCC). METHOD Western blotting, immunohistochemistry, and RT-PCR were used to identify gene expression. Cell invasion and migration were discovered using Transwell and Scratch-Wound analyses. The interaction between lncRNA and miRNA was examined using dual-luciferase and immunofluorescence assays. RESULTS We discovered that COX10-AS1 was significantly downregulated in OSCC tissues when compared to matched noncancerous tissues, indicating a dismal prognosis for OSCC patients. By raising the expression of MMP-2/-9 and Snail and lowering the expression of E-cadherin, COX10-AS1 deletion increased OSCC cell invasion and migration. Next, three binding sites between COX10-AS1 and miR-361-5p were shown in the StarBase V2.0 database. Pearson's correlation analysis revealed a negative association between the expression of COX10-AS1 and that of miR-361-5p, and miR-361-5p transfection reduced COX10-AS1's influence on OSCC cell invasion and migration. Furthermore, COX10-AS1 favorably regulated SPRY1, a miR-361-5p target gene. CONCLUSION Through the miR-361-5p/SPRY1 axis, COX10-AS1 can act as a tumor suppressor and is decreased in OSCC.

Abstract
Transforming growth factor β (Tgf-β), a pleiotropic cytokine, can enhance DNA repair in various cells, including cancer cells and neurons. The noncoding regulatory system plays an important role in Tgf-β-mediated biological activities, whereas few studies have explored its role in DNA damage and repair. In this study, we suggested that Tgf-β improved while its inhibitor LSKL impaired DNA repair and cell viability in UV-irradiated 661W cells. Moreover, RNA-seq was carried out, and a total of 106 differentially expressed (DE)-mRNAs and 7 DE-lncRNAs were identified between UV/LSKL and UV/ctrl 661W cells. Gene ontology and Reactome analysis confirmed that the DE-mRNAs were enriched in multiple DNA damaged- and repair-related biological functions and pathways. We then constructed a ceRNA network that included 3 lncRNAs, 19 miRNAs, and 29 mRNAs with a bioinformatics prediction. Through RT-qPCR and further functional verification, 2 Tgf-β-mediated ceRNA axes (Gm20559-miR-361-5p-Oas2/Gbp7) were further identified. Gm20559 knockout or miR-361-5p mimics markedly impaired DNA repair and cell viability in UV-irradiated 661W cells, which confirms the bioinformatics results. In summary, this study revealed that Tgf-β could reduce DNA damage in 661W cells, provided a Tgf-β-associated ceRNA network for DNA damage and repair, and suggested that the molecular signatures may be useful candidates as targets of treatment for photoreceptor pathology.

Abstract
OBJECTIVES This study is aimed to explore the key role of miR-361-5p in fibroblast-like synovial (FLS) cells of rheumatoid arthritis (RA) and explore the underlying mechanism. METHODS First, we performed RT-qPCR to evaluate the expression of miR-361-5p in both synovial tissues of RA patients and cultured RA-FLS cells. Then CCK-8 assay, EdU staining, Western blot, flow cytometry, and ELISA were conducted to estimate the influence of inhibiting miR-361-5p on RA-FLS cells. Moreover, we used bioinformatics analysis to predict the potential targets of miR-361-5p and perform a dual luciferase report assay for verification. Finally, rescue experiments were performed to prove the role of miR-361-5p/Zinc Finger And BTB Domain Containing 10 (ZBTB10) in the proliferation, cell cycle, and apoptosis of RA-FLS. RESULTS We find that the expression of miR-361-5p is increased in both RA tissues and cultured RA-FLS cells. The inhibition of miR-361-5p can not only inhibit proliferation, arrest the cell cycle in G1/G0 phase, and increase apoptosis, but also reduce the inflammatory factors secreted by RA-FLS cells. In addition, ZBTB10 is a direct target for miR-361-5p, over-expression of ZBTB10 reverses the effect of miR-361-5p in RA-FLS. CONCLUSIONS MiR-361-5p promotes the progression of rheumatoid arthritis by targeting ZBTB10. Key pointsThe influences of miR-361-5p on RA-FLS cells.

Abstract
Ovarian cancer (OC) progression is related to many functional molecules, including circular RNAs (circRNAs). Hsa_circ_0061140 (circ_0061140) promoted cell growth and metastasis in OC. The aim of this study was to explore a specific functional mechanism of circ_0061140. Reverse transcription-quantitative polymerase chain reaction was performed for expression analysis of circ_0061140, microRNA-361-5p (miR-361-5p), and Ras-like protein in rat brain 1A (RAB1A). Cell proliferation was determined using Cell Counting Kit-8 assay, EdU assay, and colony formation assay. The migration and invasion were assessed through transwell assay. Tube formation assay was used for angiogenesis analysis. Cell apoptosis was evaluated using flow cytometry. The protein levels of epithelial-to-mesenchymal transition (EMT) markers and RAB1A were detected via western blot. Target analysis was performed by dual-luciferase reporter assay and RNA immunoprecipitation assay. In vivo research was conducted using xenograft model. The circ_0061140 level was upregulated in OC samples and cells. Downregulation of circ_0061140 impeded proliferation, migration, invasion, EMT, and angiogenesis of OC cells. Circ_0061140 directly interacted with miR-361-5p to act as a miRNA sponge. The miR-361-5p inhibition reversed the si-circ_0061140-induced anti-tumor function in OC cells. RAB1A was a downstream target of miR-361-5p, and miR-361-5p served as a tumor repressor in OC via inhibiting the level of RAB1A. Circ_0061140 could increase the RAB1A expression by sponging miR-361-5p in OC cells. Circ_0061140 also facilitated tumorigenesis in vivo through targeting the miR-361-5p/RAB1A axis. All results demonstrated that circ_0061140 promoted OC development by inhibiting miR-361-5p to upregulate the expression of RAB1A.

Abstract
Purpose Chronic obstructive pulmonary disease (COPD), a progressive and irreversible respiratory disease, becomes the third leading cause of death and results in enormous economic burden on healthcare costs and productivity loss worldwide by 2020. Thus, it is urgent to develop effective anti-COPD drugs. Materials and Methods In the present study, two published GEO profiles were used to re-analyze and ascertain the relationships between circulating miRNAs and bronchial epithelial cells (BECs) mRNAs in COPD. The microRNA levels of miR-361-5p and miR-196-5p in plasma of COPD patients and healthy volunteers were detected by qRT-PCR. Next, the effects of γ-sitosterol (GS) on the expression of miR-361-5p and miR-196-5p and cell proliferation were investigated in BEC and H292 cell lines. Finally, whether specific miRNA-mRNA pathways involved in the effect of GS on BECs was assayed using Western Blot, real-time PCR and immunofluorescence. Results miR-196-5p and miR-361-5p were, respectively, up- and down-regulated in COPD patients compared with healthy controls. Luciferase assays demonstrated that miR-361-5p and miR-196-5p were, respectively, targeting abca1 and arhgef12 3ʹUTR in BEAS-2B cells. GS significantly suppressed miR-196-5p and promoted miR-361-5p levels in BEAS-2B cells and inhibited BECs proliferation in vitro. GS promoted miR-361-5p expression, which inhibited BCAT1 mRNA and protein levels and weaken mTOR-pS6K pathway, resulted in anti-proliferation in BEAS-2B cells. In addition, RhoA was activated by ARHGEF12 due to the inhibitory effect of miR-196-5p on arhgef12-3ʹUTR which was partially abolished by GS suppressing miR-196-5p expression. Activated RhoA further activated ROCK1-PTEN pathway and finally inhibited mTOR pathway, resulting in induced BECs proliferation. The anti-proliferation effect of GS was not observed in H292 cells. Conclusion These findings indicate that miR-361-5p/abca1 and miR-196-5p/arhgef12 axis mediated GS inducing dual anti-proliferation effects on BECs.

Abstract
Rheumatoid arthritis (RA) is an inflammatory disease that causes hyperplasia of synovial tissue and cartilage destruction. This research was to investigate the effects of lncRNA GAS5/miR-361-5p/PDK4 on rheumatoid arthritis. By qRT-PCR, GAS5 and PDK4 were found to be overexpressed in synovial tissue, fibroblast-like synoviocytes of RA patients and LPS-induced chondrocytes, while the miR-361-5p expression was significantly reduced. GAS5 overexpression resulted in a decrease in the proliferation and Bcl-2 protein expression, and an increase in the Bax protein level. On the contrary, miR-361-5p sponged by GAS5 could accelerate chondrocyte proliferation, inhibit apoptosis. PDK4 targeted by miR-361-5p could inhibit RA, and partially eliminated the effect of miR-361-5p on RA. Our study suggested that GAS5 suppressed RA by competitively adsorbing miR-361-5p to modulate PDK4 expression.

Abstract
Cutaneous squamous cell carcinoma (CSCC) is one of the most malignant tumors worldwide. It has been validated that matrix metallopeptidase 1 (MMP1) expression was obviously up-regulated in CSCC tissues. However, its specific role in CSCC is still unclear. RT-qPCR analysis and western blot assays were used to measure the mRNA and protein expressions, respectively. MTT and colony formation assays were conducted to assess proliferative ability. Transwell assays were adopted to evaluate migratory and invasive abilities. Flow cytometry and caspase-3/8/9 activity assays were carried out to evaluate cell apoptosis. Relevant mechanism experiments were finally performed to delineate molecular relationship among genes. We found that the expression of MMP1 was up-regulated in CSCC cells, and knockdown of MMP1 suppressed cell proliferation and invasion in CSCC. Subsequently, miR-361-5p was validated to target MMP1. Moreover, miR-361-5p was proved to be sponged by nuclear paraspeckle assembly transcript 1 (NEAT1) in CSCC. We further demonstrated that NEAT1 could activate Wnt pathway to affect cell proliferation and invasion. Finally, miR-361-5p inhibition rescued the suppressing effects of NEAT1 depletion on cell proliferation, invasion as well as Wnt pathway in CSCC. In summary, MMP1 regulated by NEAT1/miR-361-5p axis facilitated CSCC malignant behaviors via Wnt pathway activation.

Abstract
In recent years, the role of circular RNAs (circRNAs) in tumours has attracted widespread attention. Some circRNAs have been reported to play a role in triple-negative breast cancer (TNBC). However, circRNAs have rarely been reported in terms of TNBC resistance. This study aimed to clarify that circGFRA1 affects the sensitivity of TNBC cells to paclitaxel (PTX) by the miR-361-5p/TLR4 pathway. Compared with the non-PTX-resistant TNBC cell line MDA-MB-231, the expression of circGFRA1 in the PTX-resistant TNBC cell line MDA-MB-231.PR was significantly increased. The small hairpin RNA-mediated circGFRA1 knockdown inhibited the resistance of TNBC cells to PTX. RNA pull-down assay and luciferase reporter gene assay confirmed the binding between circGFRA1 and miR-361-5p and between miR-361-5p and TLR4. It has been proven that circGFRA1 knockdown can inhibit the resistance of TNBC cells to PTX by promoting the expression of miR-361-5p, and subsequently reduce the expression of TLR4.

Abstract
Osteoarthritis (OA) is a chronic disease featured by joint hyperplasia, deterioration of articular cartilage, and progressive degeneration. Abnormal expression of microRNAs (miRNAs) has been found to be implicated in the pathological process of OA. In this study, the role of miR-361-5p transferred by exosomes derived from human bone mesenchymal stem cells (hBMSCs) in OA was investigated. The expression of Asp-Glu-Ala-Asp-box polypeptide 20 (DDX20) and miR-361-5p in interleukin-1β (IL-1β)-treated chondrocytes was determined by reverse transcription quantitative polymerase chain reaction. DDX20 was knocked down by transfection of short hairpin RNA targeting DDX20, and the effects of DDX20 downregulation on IL-1β-induced damage of chondrocytes were detected. The interaction between DDX20 and miR-361-5p was tested by luciferase report assay. hBMSCs-derived exosomes loaded with miR-361-5p were co-incubated with chondrocytes followed by detection of cell viability, proliferation and inflammatory response. An OA rat model was established to further explore the role of miR-361-5p in vivo. Western blot, luciferase reporter and immunofluorescence staining assays were used to evaluate the activation of the nuclear factor kappa-B (NF-κB) signaling pathway. We found that DDX20 was upregulated, while miR-361-5p was underexpressed in IL-1β-treated chondrocytes. Downregulation of DDX20 inhibits levels of matrix metalloproteinases (MMPs) and suppresses inflammation induced by IL-1β. Mechanistically, miR-361-5p was verified to directly target DDX20. In addition, hBMSC-derived exosomes-transferred miR-361-5p alleviates chondrocyte damage and inhibits the NF-κB signaling pathway via targeting DDX20. Inhibition of NF-κB signaling reverses the effect of overexpressed DDX20 on IL-1β-induced chondrocyte damage. Moreover, exosomal miR-361-5p alleviates OA damage in vivo. Overall, hBMSC-derived exosomal miR-361-5p alleviates OA damage by targeting DDX20 and inactivating the NF-κB signaling pathway.

Abstract
Transplantion of bone marrow-derived endothelial progenitor cells (EPCs) may be a novel treatment for deep venous thrombosis (DVT). The present study probed into the role of microRNA (miR)-361-5p in EPCs and DVT recanalization. EPCs were isolated from male Sprague-Dawley (SD) rats and identified using confocal microscopy and flow cytometry. The viability, migration and tube formation of EPCs were examined using MTT assay, wound-healing assay and tube formation assay, respectively. Target gene and potential binding sites between miR-361-5p and fibroblast growth factor 1 (FGF1) were predicted by StarBase and confirmed by dual-luciferase reporter assay. Relative expressions of miR-361-5p and FGF1 were detected using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot as needed. A DVT model in SD rats was established to investigate the role of EPC with miR-361-5p antagomir in DVT by Hematoxylin-Eosin (H&E) staining. EPC was identified as 87.1% positive for cluster of difference (CD)31, 2.17% positive for CD133, 85.6% positive for von Willebrand factor (vWF) and 94.8% positive for vascular endothelial growth factor receptor-2 (VEGFR2). MiR-361-5p antagomir promoted proliferation, migration and tube formation of EPCs and up-regulated FGF1 expression, thereby dissolving thrombus in the vein of DVT rats. FGF1 was the target of miR-361-5p, and overexpressed FGF1 reversed the effects of up-regulating miR-361-5p on suppressing EPCs. Down-regulation of miR-361-5p enhanced thrombus resolution in vivo and promoted EPC viability, migration and angiogenesis in vitro through targeting FGF1. Therefore, miR-361-5p may be a potential therapeutic target for DVT recanalization.

Abstract
Follicular atresia is an inevitable degenerative process that occurs in mammalian ovarian follicles. The molecular events involved in atresia, particularly granulosa cell apoptosis, have long attracted researchers’ attention. Vascular endothelial growth factor A (VEGFA) is downregulated during follicular atresia in porcine ovaries and serves as an inhibitor of apoptosis in granulosa cells. In addition, transforming growth factor (TGF)-βsignaling has been considered a central trigger in granulosa cell apoptosis. However, the link between TGF-β signaling and VEGFA is unknown. We proved that miR-361-5p is significantly upregulated during the atresia process and that it promotes GC apoptosis by directly targeting the VEGFA 3′UTR. In addition, we revealed that the miR-361-5p coding gene MIR361 was significantly downregulated by SMAD4, the central intracellular mediator of TGF-β signaling, that bound to the MIR361 promoter. In conclusion, our findings expanded what is known about VEGFA posttranscriptional regulation and revealed a complete SMAD4/miR-361-5p/VEGFA regulatory network in ovarian granulosa cell apoptosis. These data provide useful references for follicular atresia and ovarian physiological function studies.

Abstract
Background Glioma is the most primary central nervous system tumor in adults. The 5 year survival rate for glioma patients remains poor, although treatment strategies had improved in the past few decades. The cumulative studies have shown that circular RNA (circRNA) is associated with glioma process, so the purpose of this study is to clarify the function of circPOSTN in glioma. Methods The expression levels of circPOSTN, miR-361-5p, and targeting protein for Xenopus kinesin-like protein 2 (TPX2) were assessed with real-time quantitative polymerase chain reaction (RT-qPCR). The 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl-2H-tetrazol-3-ium bromide (MTT) and flow cytometry assays were executed to examine proliferation and apoptosis of glioma cells, respectively. Western blot was applied to assess protein expression. The glucose metabolism of glioma cells was analyzed by testing the glucose consumption, lactate production, ATP level, reactive oxygen species (ROS) accumulation and performing Seahorse XF assay. The interaction relationship between miR-361-5p and circPOSTN or TPX2 was analyzed by bioinformatics database and dual-luciferase reporter assay. The influences of circPOSTN silencing in vivo were observed by a xenograft experiment. Results CircPOSTN was overexpressed in glioma tissues and cells. Absence of circPOSTN in glioma cells promoted apoptosis while impeded proliferation and aerobic glycolysis, which were mitigated by silencing miR-361-5p. What’s more, loss-of-functional experiment suggested that knockdown of TPX2 repressed proliferation and aerobic glycolysis, while induced apoptosis in glioma cells. In addition, circPOSTN targetedly regulated TPX2 expression in glioma cells via sponging miR-361-5p. In vivo study revealed that deficiency of circPOSTN restrained tumor growth. Conclusion Mechanistically, circPOSTN regulated cell growth, apoptosis, and aerobic glycolysis in glioma through miR-361-5p/TPX2 axis.

Abstract
PURPOSE MiR-361-5p has been reported to act as tumor suppressor in several types of cancers. Retinoblastoma (RB) is the most common ocular tumor in childhood. The current study aimed to investigate the expression pattern and biological function of miR-361-5p in RB. METHODS Quantitative real time was utilized to determine and compare the expression of miR-361-5p in RB cells and normal retinal pigment epithelial cell line ARPE-19. CCK-8 and Edu assay were performed to assess cell proliferation. Cell apoptosis was evaluated using flow cytometry assay. Bioinformatics databases and luciferase reporter assay were applied to predict and confirm the target gene of miR-361-5p in RB cells. RESULTS Here, we found miR-361-5p was significantly downregulated in RB cells compared with normal retinal pigment epithelial cell line ARPE-19. MiR-361-5p overexpression significantly inhibited or silencing promoted cell proliferation in Y79 and SO-RB50 cells, respectively. Flow cytometry assay showed a significantly decreased cell apoptosis in miR-361-5p silencing Y79 cells and increased cell apoptosis in miR-361-5p overexpressing SO-RB50 cells. Moreover, miR-361-5p directly bound to the 3' untranslated region of claudin 8 (CLDN8) and inhibited the expression of CLDN8. Furthermore, we found knockdown of CLDN8 photocopied the effect of miR-361-5p on cell proliferation and apoptosis in RB cells. CONCLUSION These results indicated that overexpression of miR-361-5p might act as a suppressor in RB by targeting CLDN8 to inhibit the cellular function.

Abstract
Long non-coding RNAs (lncRNAs) have been identified as critical players in tumorigenesis. Previous studies revealed that lncRNA SBF2-AS1 was involved in tumor progression. However, the role and underlying mechanism of SBF2-AS1 in cervical cancer (CC) remain unknown. In the present study, our data showed that SBF2-AS1 expression was significantly increased in CC. High SBF2-AS1 expression was associated with advanced FIGO stage and lymph node metastasis of CC patients. Function assays showed that SBF2-AS1 inhibition significantly reduced CC cells proliferation both in vitro and in vivo. Mechanistically, we showed that SBF2-AS1 upregulation restrained the activity of miR-361-5p and led to overexpression of FOXM1 in CC cells. Furthermore, we found that miR-361-5p inhibitors could rescue the effects of SBF2-AS1 inhibition on CC cells proliferation. Taken together, we demonstrated that the SBF2-AS1/miR-361-5p/FOXM1 axis might play an important role in CC progression. SBF2-AS1 might serve as a potential therapeutic target for CC treatment.

Abstract
Background Downregulation of miR-361-5p contributes to epithelial–mesenchymal transition of glioma cells. However, the relevance of miR-361-5p to migration and invasion of gliomas remains unknown. Materials and methods The relationship between miR-361-5p and SND1 expression was analyzed in 120 human gliomas and 8 glioma cell lines by in situ hybridization, immunohistochemistry, and Western blot. Dual-luciferase reporter assay was used to identify SND1 as a target of miR-361-5p. The mechanisms through which miR-361-5p inhibits glioma cell migration and invasion were studied by in vitro assays. Results miR-361-5p expression was significantly downregulated in glioma tissues and glioma cell lines, and was inversely correlated with glioma grades. However, SND1 expression was positively correlated with glioma grades and inversely correlated with miR-361-5p expression. miR-361-5p overexpression suppressed glioma cell migration and invasion through targeting SND1 and subsequently decreasing MMP-2 expression. In glioma cell lines, SND1 overexpression could partly reverse the antitumor effects of miR-361-5p. Conclusion The findings provide evidence that miR-361-5p directly targets SND1 to degradation and then reduces MMP-2 gene transcription, thus inhibiting glioma migration and invasion. miR-361-5p is an important tumor suppressor and a novel diagnostic biomarker of glioma, and miR-361-5p and SND1 are potential therapeutic candidates for malignant gliomas.

Abstract
A large number of studies have shown that miRNAs are important regulators of epithelial-to-mesenchymal transition (EMT) and are associated with metastasis in epithelial ovarian cancer (EOC). MiR-361-5p has been shown to play pivotal roles in tumorigenesis and metastasis; however, a role for miR-361-5p in EOC has not been reported. In this study, we found that miR-361-5p was significantly down-regulated in EOC tissues and cell lines. In addition, over-expression of miR-361-5p inhibited the migration and invasion of EOC cells in vitro. MiR-361-5p influenced the expression of the EMT-associated proteins by upregulating the epithelial marker E-cadherin and downregulating the mesenchymal markers, N-cadherin and vimentin. Further studies identify miR-361-5p directly targeted Ribosomal L22-like1 (RPL22L1) and c-Met. Moreover, miR-361-5p repressed the Akt/mTOR pathway after c-Met inhibition. Reintroduction of RPL22L1 and c-Met reversed miR-361-5p-induced EMT suppression. Consistently, inverse correlations were also observed between the expression of miR-361-5p and RPL22L1 or c-Met in human EOC tissue samples. Taken together, miR-361-5p inhibited the EMT progression in EOC cells by targeting RPL22L1 and c-Met/Akt/mTOR signaling.

Abstract
MicroRNAs function as key regulators in various human cancers, including papillary thyroid cancer (PTC). MiR-361-5p has been proved to be a tumor suppressor in multiple cancers. However, the function of miR-361-5p in PTC remains unknown. In this study, we aimed to determine the function of miR-361-5p in PTC progression, and elaborate the mechanism by which miR-361-5p acts in PTC. Here, we report that miR-361-5p expression levels were significantly downregulated in PTC tissues and cell lines, as detected by reverse transcription-quantitative polymerase chain reaction (qRT-PCR) analysis. Functional analysis revealed that overexpression of miR-361-5p significantly inhibited cell proliferation, migration, invasion in vitro, as well as suppressed tumor growth in vivo. Bioinformatic analysis showed that Rho-associated coiled-coil kinase 1 (ROCK1) was a predicted target of miR-361-5p, which was further validated by the dual-luciferase reporter assay, qRT-PCR, and western blot analysis. In addition, an inverse expression pattern was also observed between miR-361-5p and ROCK1 in a cohort of PTC tissues. Rescue experiments showed that restoration of ROCK1 expression significantly reversed the suppressive effect of miR-361-5p on cell proliferation, migration, and invasion in PTC cells. Taken together, these findings suggest that miR-361-5p is a novel potential therapeutic target for thyroid cancer.

Abstract
MicroRNAs play a crucial role in the progression of pulmonary arterial hypertension (PAH). The aim of this study was to investigate the effect of miR-361-5p on the proliferation, migration and apoptosis of pulmonary artery smooth muscle cells (PASMCs) that under the treatment of hypoxia and explore the underlying mechanisms. The results proved that hypoxia noticeably up-regulated the expression of miR-361-5p in PASMCs in comparison to the normoxia-treated cells, while TNF-α and IL-6 stimulation had no obvious effects on miR-361-5p level. Hypoxia induced miR-361-5p elevation in a HIF-1α-dependent manner. Inhibition of miR-361-5p dramatically inhibited hypoxia-induced cell proliferation and migration. miR-361-5p inhibition also rescued hypoxia exposure caused suppression of PASMCs apoptosis. In addition, the results showed that ABCA1 was a direct target of miR-361-5p and was down-regulated in hypoxia-induced PASMCs. Hypoxia and TNF-α or IL-6 stimulation significantly inhibited ABCA1 expression. In addition, overexpression of ABCA1 enhanced the effect of miR-361-5p on hPASMCs. Furthermore, the inhibition of miR-361-5p significantly down-regulated the expression level of p-JAK2 and p-STAT3. In conclusion, it may suggest that the suppression of miR-361-5p suppressed PASMC survival and migration by targeting ABCA1 and inhibiting the JAK2/STAT3 pathway.

Abstract
Background MicroRNAs function as key regulators in various human cancers, including breast cancer (BC). MiR-361-5p has been proved to be a tumor suppressor in colorectal cancer and gastric cancer in our previous study. In this study, we aim to find out the function of miR-361-5p in breast cancer progression and elaborate the mechanism that miR-361-5p acts its function in breast cancer. Methods and results Here we reported that miR-361-5p was down-regulated in breast cancer tissue compared with normal breast tissue and the expression of miR-361-5p was positively associated with prognosis in BC patients. Functional studies showed that overexpression of miR-361-5p suppressed the proliferation, invasion and metastasis of breast cancer cells both in vivo and in vitro. Mechanistically, we found that miR-361-5p inhibited the proliferation of BC cells by suppressing glycolysis. FGFR1, a promoter of glycolysis-related enzyme, was identified as the target of miR-361-5p that promoted glycolysis and repressed oxidative phosphorylation. Furthermore, we demonstrated that miR-361-5p inhibited breast cancer cells invasion and metastasis by targeting MMP-1. An inverse expression pattern was also found between miR-361-5p and FGFR1 or MMP-1 in a cohort of 60 BC tissues. Conclusion Our results indicate that miR-361-5p inhibits breast cancer cells glycolysis and invasion by respectively repressing FGFR1 and MMP-1, suggesting that miR-361-5p and its targets may serve as therapeutic targets in breast cancer treatment.

Abstract
Atherosclerotic lesions are characterized by the accumulation of abundant lipids and chronic inflammation. Previous researches have indicated that macrophage-derived lipoprotein lipase (LPL) promotes atherosclerosis progression by accelerating lipid accumulation and pro-inflammatory cytokine secretion. Although apelin-13 has been regarded as an atheroprotective factor, it remains unclear whether it can regulate the expression of LPL. The aim of this study was to explore the effects of apelin-13 on the expression of LPL and the underlying mechanism in THP-1 macrophage-derived foam cells. Apelin-13 significantly decreased cellular levels of total cholesterol, free cholesterol, and cholesterol ester at the concentrations of 10 and 100 nM. ELISA analysis confirmed that treatment with apelin-13 reduced pro-inflammatory cytokine secretion, such as interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor-alpha (TNF-α). It was also found that apelin-13 inhibited the expression of LPL as revealed by western blot and real-time PCR analyses. Bioinformatics analyses and dual-luciferase reporter assay indicated that miR-361-5p directly downregulated the expression of LPL by targeting the 3'UTR of LPL. In addition, apelin-13 + miR-361-5p mimic significantly downregulated the expression of LPL in cells. Finally, we demonstrated that apelin-13 downregulated the expression of LPL through activating the activity of PKCα. Taken together, our results showed that apelin-13 downregulated the expression of LPL via activating the APJ/PKCα/miR-361-5p signaling pathway in THP-1 macrophage-derived foam cells, leading to inhibition of lipid accumulation and pro-inflammatory cytokine secretion. Therefore, our studies provide important new insight into the inhibition of lipid accumulation and pro-inflammatory cytokine secretion by apelin-13, and highlight apelin-13 as a promising therapeutic target in atherosclerosis.

Abstract
MicroRNAs (miRNAs) play important roles in the pathogenesis of many types of cancers by negatively regulating gene expression at posttranscriptional level. Here, we found that miR-361-5p is down-regulated in 135 patients with HCV-related hepatocellular carcinoma (HCC). Moreover, the expressions of miR-361-5p were highly correlated with VEGFA in these HCC patients. Further, CCK-8 proliferation assay indicated that miR-361-5p mimics inhibited the cell proliferation of HepG2 and SNU-398 HCC cells. Transwell assay showed that miR-361-5p mimics inhibited the invasion and migration of HepG2 and SNU-398 HCC cells. Luciferase assays revealed that miR-361-5p directly bound to the 3'untranslated region of VEGFA, and western blotting showed that miR-361-5p inhibited the expression of VEGFA. Generally, this study indicated that miR-361-5p is down-regulated in HCC and inhibits proliferation and invasion of HCC cell lines via VEGFA. In future, miR-361-5p will be a potential therapeutic agent for HCC.

Abstract
MicroRNAs (miRs) function as key regulators of gene expression and their deregulation is associated with the carcinogenesis of various cancers. In the present study, we investigated the biological role and mechanism of miR-361-5p in colorectal carcinoma (CRC) and gastric cancer (GC). We showed that microRNA-361-5p (miR-361-5p) was down-regulated in CRC and GC in comparison to the controls. Meanwhile, the expression levels of miR-361-5p negatively correlated with lung metastasis and prognosis in clinical CRC patients. Overexpression of miR-361-5p markedly suppressed proliferation, migration and invasion of cancer cells. Additionally, this phenotype could be partially rescued by the ectopic expression of staphylococcal nuclease domain containing-1 (SND1). SND1 was identified as a target of miR-361-5p using bioinformatics analysis and in vitro luciferase reporter assays. In turn, SND1 bound to pre-miR-361-5p and suppressed the expression of miR-361-5p, thus exerting a feedback loop. Most interestingly, in vivo studies showed that restoration of miR-361-5p significantly inhibited tumor growth and especially the lung metastasis in nude mice. Therefore, it could be concluded that miR-361-5p functions as a tumor-suppressive miRNA through directly binding to SND1, highlighting its potential as a novel agent for the treatment of patients with CRC and GC.
