Abstract
BACKGROUND Osteoporosis (OP) is a progressive metabolic disorder that is difficult to cure clinically. The molecular mechanisms of OP urgently need to be further examined. This study was designed to explore the potential function of circ_0027885 during osteogenic differentiation, as well as the systematic interactions among circ_0027885, miR-203-3p and runt-related transcription factor 2 (RUNX2). METHODS Relative levels of circ_0027885, miR-203-3p and RUNX2 were analyzed with RT-qPCR and western blotting. Alizarin red staining was performed to detect the mineralization ability under the control of circ_0027885 and miR-203-3p. Dual-luciferase reporter gene assay was conducted to examine the combination among circ_0027885, miR-203-3p and RUNX2. RESULTS Our research demonstrated that circ_0027885 was significantly increased during hBMSCs differentiation. Overexpression of circ_0027885 notably facilitated osteogenic differentiation and upregulated RUNX2 expression, while knockdown of circ_0027885 reversed the above results. Through prediction on bioinformatics analysis, miR-203-3p was the target binding circ_0027885, and RUNX2 was the potential target of miR-203-3p. Subsequently, these changes induced by the overexpression of circ_0027885 were reversed upon addition of miR-203-3p mimic. CONCLUSIONS Circ_0027885 could sponge miR-203-3p to regulate RUNX2 expression and alleviate osteoporosis progression.

Abstract
AIMS As a severe cardiovascular disease, acute myocardial infarction (AMI) could trigger congestive heart failure. Periostin (Postn) has been elucidated to be dramatically up-regulated in myocardial infarction. Abundant expression of Postn was also observed in the infarct border of human and mouse hearts with AMI. This work is dedicated to explore the mechanism through which Postn exerts its functions on AMI. METHODS AND RESULTS The expression of Postn in AMI mice and hypoxia-treated neonatal mouse cardiomyocytes (NMCMs) was quantified by qRT-PCR. The biological functions of Postn in AMI were explored by trypan blue, TUNEL, flow cytometry analysis, and JC-1 assays. Luciferase activity or MS2-RIP or RNA pull-down assay was performed to study the interaction between genes. Postn exhibited up-regulated expression in AMI mice and hypoxia-treated NMCMs. Functional assays indicated that cell apoptosis in NMCMs was promoted via the treatment of hypoxia. And Postn shortage could alleviate cell apoptosis in hypoxia-induced NMCMs. Postn was verified to bind to mmu-miR-203-3p and be down-regulated by miR-203-3p overexpression. Postn and miR-203-3p were spotted to coexist with small nucleolar RNA host gene 8 (Snhg8) in RNA-induced silencing complex. The affinity between Snhg8 and miR-203-3p was confirmed. Afterwards, Snhg8 was validated to promote cell apoptosis in hypoxia-induced NMCMs partially dependent on Postn. Furthermore, vascular endothelial growth factor A (Vegfa) was revealed to bind to miR-203-3p and be implicated in the Snhg8-mediated AML cell apoptosis and angiogenesis. CONCLUSIONS miR-203-3p availability is antagonized by Snhg8 for Postn and Vegfa-induced AMI progression.

Abstract
BACKGROUND Lung cancer is the most common malignancy, and its mortality ranks first among malignancies. Non-small cell lung carcinoma (NSCLC) is the most common pathological subtype of lung cancer. It is reported that circular RNAs (circRNAs) feature prominently in the occurrence and metastasis of NSCLC. PURPOSE This study aims to decipher the biological functions of circ_0006220 in NSCLC and the underlying mechanism. METHODS The microarray data (GSE101586) were downloaded from the Gene Expression Omnibus database, and differentially expressed circRNAs in NSCLC tissues were screened using the GEO2R tool. Quantitative real-time polymerase chain reaction was used for detecting the expression of circ_0006220, miR-203-3p, and regulator of G-protein signaling 17 (RGS17) mRNA in NSCLC tissues and cells. The connection between circ_0006220 expression and clinicopathological indicators was analyzed through the chi-square test. EdU and cell counting kit-8 assays were carried out to detect cell growth. Cell migration and invasion were detected by transwell assays. Bioinformatics was used to predict, and RNA immunoprecipitation assay and dual-luciferase reporter gene assay were conducted for verifying, the targeted relationship among circ_0006220, miR-203-3p, and RGS17. RESULTS The expression of circ_0006220 was elevated in NSCLC cells and tissues, and high circ_0006220 expression was significantly associated with unfavorable clinicopathological indicators. In addition, it was revealed that circ_0006220 overexpression facilitated NSCLC cell growth, migration, and invasion, whereas knocking down circ_0006220 had contrary effects. Furthermore, miR-203-3p was identified as a downstream target of circ_0006220, and circ_0006220 could sponge miR-203-3p; RGS17 was identified as a downstream target of miR-203-3p and was positively modulated by circ_0006220. CONCLUSIONS Circ_0006220 up-regulates RGS17 expression by adsorbing miR-203-3p to promote NSCLC development.

Abstract
Background: Bone fracture is a common medical condition. Evidence suggested that long noncoding RNAs (lncRNAs) could regulate the bio-function in osteoblast. In this study, we explored the role and mechanism of lncRNA X-inactive specific transcript (XIST) on the proliferation, apoptosis, and differentiation of osteoblasts using MC3T3-E1 cells. Methods: Expression of XIST, microRNA-203-3p (miR-203-3p), and zinc finger protein multitype 2 (ZFPM2) was measured by quantitative real-time polymerase chain reaction (qRT-PCR). Cell viability and apoptosis of MC3T3-E1 cells were measured using the Cell Counting Kit-8 (CCK-8) and the flow cytometry. Western blot was used to measure the expression of cell cycle-related proteins, apoptosis-related proteins, and ZFPM2. Levels of differentiation-related factors were measured by qRT-PCR, western blot, and alkaline phosphatase (ALP) kit. Target interaction between miR-203-3p and XIST or ZFPM2 was predicted through bioinformatics analysis and verified by dual-luciferase reporter, RNA immunoprecipitation (RIP) assay, or RNA pull-down assay. Results: The expression of XIST and ZFPM2 was increased while miR-203-3p was decreased in plasmas and MC3T3-E1 cells. Knockdown of XIST promoted the proliferation, differentiation, but limited apoptosis in MC3T3-E1 cells. . Mechanically, overexpression of XIST could reverse the bio-function of miR-203-3p transfection. Additionally, miR-203-3p inverted a series of bio-functional effects of ZFPM2. Furthermore, anti-miR-203-3p rescued si-XIST-induced downregulation of ZFPM2. Conclusion: Downregulation of lncRNA XIST promoted osteoblast proliferation and differentiation, but limited apoptosis by miR-203-3p/ZFPM2 axis.

Abstract
Diabetic nephropathy (DN) is the most serious long-term microvascular complication of diabetes, which mainly causes podocyte injury. Many studies have shown that microRNAs play a vital role in the development of DN. Studies have shown that miR-203-3p is involved in mesangial cell proliferation and apoptosis of DN mice. Therefore, we speculated that miR-203-3p might be related to the development of DN, but our study does not provide any evidence. In animal experiments, diabetic mice (db/db) were transfected with iR-203-3p overexpression lentiviral vectors (LV-miR-203-3p) and their control (LV-miR-con), with normal mice (db/m) being used as the control. High glucose (HG)-induced podocytes were used to construct a DN cell model in vitro. The expression levels of miR-203-3p, Semaphorin 3A (Sema3A) and inflammatory cytokines were detected by quantitative real-time polymerase chain reaction. Also, serum creatinine and blood urea nitrogen levels were used to evaluate the degree of renal injury in DN mice. Sema3A and apoptosis-related protein levels were assessed by the western blot analysis. Enzyme-linked immunosorbent assay was used to determine the different oxidative stress-related indicators and inflammatory cytokines. Flow cytometry and caspase-3 activity detection were used to analyze the degree of podocyte apoptosis. Our results suggested that the expression of miR-203-3p was lower in DN mice and in HG-induced podocytes. Overexpression of miR-203-3p reduced the body weight, blood glucose and renal injury of DN mice in vivo, as well as relieve the oxidative stress, inflammatory response and apoptosis of HG-induced podocytes in vitro. Functionally, Sema3A was a target of miR-203-3p, and Sema3A overexpression reversed the inhibitory effect of miR-203-3p on HG-induced podocyte injury. Our findings revealed that miR-203-3p alleviated the podocyte injury induced by HG via regulating Sema3A expression, suggesting that miR-203-3p might be a new therapeutic target to improve the progression of DN.

Abstract
This study aimed to identify key genes (microRNA and messenger RNA (mRNA)) and associated signaling-regulated pathways in a drug-induced epilepsy model in mice by microarray profiling. The related microarray dataset of seizures was obtained from the NCBI Gene Expression Omnibus database (GEO), and differentially expressed genes (DEGs) between two control samples or multi-treated samples and samples were analyzed using the statistical software R. To identify the expected function of DEGs, Gene Set Enrichment Analysis (GSEA) was utilized to conduct Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. The interaction relationship between microRNAs (miRNAs) and mRNAs in normal and epilepsy mouse models was identified using Cytoscape software. TargetScan7.1 was applied to determine the binding sites of DEGs. The dual-luciferase assay was used to verify the target relationship between miRNA and mRNA. Four miRNAs were identified as differentially expressed genes in both 24-h and 28-day status epilepticus (SE)-treated samples. Ppp2ca expression in the mitogen-activated protein kinase (MAPK) signaling pathway was downregulated in the pilocarpine-induced SE mouse model. The expression of Ppp2ca was also downregulated in the kinase-induced SE model group compared with that in the untreated group and MAP kinase (MEK) inhibitor-treated group of mice. KEGG pathway analysis indicated that the MAPK signaling pathway was upregulated in the kinase-induced SE model group compared with that in both the untreated group and the MEK inhibitor-treated group of mice. miR-203 had a targeted relationship with Ppp2ca in both humans and mice. The miR-203-3p target Ppp2ca aggravates the seizures of the SE model in mice.
