Mechanism of Smilax china L. in the treatment of intrauterine adhesions based on network pharmacology, molecular docking and experimental validation. BMC Complement Med Ther 2024; 24:150. [PMID: 38580999 PMCID: PMC10996135 DOI: 10.1186/s12906-024-04414-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 02/27/2024] [Indexed: 04/07/2024] Open
Abstract
BACKGROUND Smilax china L. (SCL) is a traditional herbal medicine for the potential treatment of intrauterine adhesion (IUA). However, the mechanisms of action have not yet been determined. In this study, we explored the effects and mechanisms of SCL in IUA by network pharmacology, molecular docking and molecular biology experiments. METHODS Active ingredients and targets of SCL were acquired from TCMSP and SwissTargetPrediction. IUA-related targets were collected from the GeneCards, DisGeNET, OMIM and TTD databases. A protein‒protein interaction (PPI) network was constructed by Cytoscape 3.9.1 and analysed with CytoHubba and CytoNCA to identify the core targets. The DAVID tool was used for GO and KEGG enrichment analyses. Furthermore, molecular docking was employed to assess the interaction between the compounds and key targets. Finally, the mechanisms and targets of SCL in IUA were verified by cellular experiments and western blot. RESULTS A total of 196 targets of SCL were identified, among which 93 were related to IUA. Topological and KEGG analyses results identified 15 core targets that were involved in multiple pathways, such as inflammation, apoptosis, and PI3K/AKT signalling pathways. Molecular docking results showed that the active compounds had good binding to the core targets. In vitro experiments showed that astilbin (AST), a major component of SCL, significantly reduced TGF-β-induced overexpression of fibronectin (FN), activation of the PI3K/AKT signalling pathway and the expression of downstream factors (NF-κB and BCL2) in human endometrial stromal cells, suggesting that AST ameliorates IUA by mediating the PI3K/AKT/NF-κB and BCL2 proteins. CONCLUSIONS AST, a major component of SCL, may be a potential therapeutic agent for IUA. Moreover, its mechanism is strongly associated with regulation of the PI3K/AKT signalling pathway and the downstream NF-κB and BCL2 proteins. This study will provide new strategies that utilize AST for the treatment of IUA.

Abstract
Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease with limited treatment options. Circular RNAs (circRNAs) have emerged as a novel class of non-coding RNAs with diverse functions in cellular processes. This review paper aims to explore the potential involvement of circRNAs in the pathogenesis of IPF and their diagnostic and therapeutic implications. We begin by providing an overview of the epidemiology and risk factors associated with IPF, followed by a discussion of the pathophysiology underlying this complex disease. Subsequently, we delve into the history, types, biogenesis, and functions of circRNAs and then emphasize their regulatory roles in the pathogenesis of IPF. Furthermore, we examine the current methodologies for detecting circRNAs and explore their diagnostic applications in IPF. Finally, we discuss the potential utility of circRNAs in the treatment of IPF. In conclusion, circRNAs hold great promise as novel biomarkers and therapeutic targets in the management of IPF.

Abstract
BACKGROUND Circular RNAs (circRNAs) perform key regulatory functions in osteosarcoma (OS) tumorigenesis. In this study, we aimed to explore the detailed action mechanisms of circ_0049271 in OS progression. METHODS Cell colony formation, cell counting kit-8, and transwell assays were performed to assess the proliferation and invasion of OS cells. Quantitative reverse transcription-polymerase chain reaction and western blotting were used to determine the expression levels of polymerase 1 and transcript release factor (PTRF), microRNA (miR)-1197, and circ_0049271 in OS cells. Furthermore, RNA immunoprecipitation and dual luciferase assays were conducted to explore the targeted relationships among PTRF, miR-1197, and circ_0049271. Finally, a tumor formation assay was conducted to determine the effects of circ_0049271 on in vivo tumor growth in mice. RESULTS High expression levels of miR-1197 and low levels of circ_0049271 and PTRF were observed in OS cells. circ _0049271 targeted miR-1197 to mediate PTRF expression. Moreover, the proliferation and invasion of OS cells were repressed by circ_0049271 or PTRF overexpression and increased by miR-1197 upregulation. Enforced circ_0049271 also impeded tumor growth in vivo. Upregulation of miR-1197 reversed the antitumor effects of circ_0049271 on OS progression in vitro; however, PTRF overexpression attenuated the cancer-promoting effects of miR-1197 on OS in vitro. CONCLUSIONS Our findings revealed that circ_0049271 targeted the miR-1197/PTRF axis to attenuate the malignancy of OS, suggesting a potential target for its clinical treatment.

Abstract
Pulmonary fibrosis is a class of fibrosing interstitial lung diseases caused by many pathogenic factors inside and outside the lung, with unknown mechanisms and without effective treatment. Therefore, a comprehensive understanding of the molecular mechanism implicated in pulmonary fibrosis pathogenesis is urgently needed to develop new and effective measures. Although circRNAs have been widely acknowledged as new contributors to the occurrence and development of diseases, only a small number of circRNAs have been functionally characterized in pulmonary fibrosis. Here, we systematically review the biogenesis and functions of circRNAs and focus on how circRNAs participate in pulmonary fibrogenesis by influencing various cell fates. Meanwhile, we analyze the current exploration of circRNAs as a diagnostic biomarker, vaccine, and therapeutic target in pulmonary fibrosis and objectively discuss the challenges of circRNA- based therapy for pulmonary fibrosis. We hope that the review of the implication of circRNAs will provide new insights into the development circRNA-based approaches to treat pulmonary fibrosis.

Abstract
BACKGROUND Circular RNAs (circRNAs) play a crucial role in regulating various physiological processes. However, the precise regulatory mechanisms of circRNF220s in osteosarcoma (OS) are not well understood. METHODS The abundances of circRNF220, miR-330-5p, and survivin were determined using qRT-PCR. To assess the m6A accumulation in circRNF220, a methylated RNA immunoprecipitation (Me-RIP) assay was conducted. Cellular multiplication, motility, and invasion were examined using the cell Counting Kit-8 (CCK-8), EdU, colony formation, Transwell, and wound-healing assays. The binding relationships were measured through RNA immunoprecipitation (RIP) and luciferase reporter assays. In vivo functionality was assessed using xenograft models. RESULTS CircRNF220 was identified as being overexpressed in both OS cells and tissues. In vitro experiments demonstrated that silencing circRNF220 impeded the proliferation, invasion, and motility of OS cells. Similarly, in vivo studies confirmed that downregulating circRNF220 inhibited the growth of OS. Further mechanistic investigations unveiled that METTL3-modulated circRNF220 regulated the progression of OS by upregulating survivin expression through acting as a sponge for miR-330-5p. CONCLUSION The modulation of METTL3-regulated circRNF220 has been found to promote the progression of OS by modulating the miR-330-5p/survivin axis. This novel finding suggests a potentially unique approach to managing OS.

Abstract
This study was performed to determine the effect of human umbilical cord mesenchymal stem cells (hucMSCs) treatment on pulmonary fibrosis and investigate the circFOXP1-mediated autophagic mechanism of hucMSCs treatment. Pulmonary fibrosis models were established by spraying bleomycin in mice and TGF-β1 treatment of MRC-5 cells. Results showed that hucMSCs were retained in lung and hucMSCs treatment alleviated pulmonary fibrosis. Morphological staining indicated that hucMSCs-treated mice had thinner alveolar walls, effectively improved alveolar structure, significantly reduced alveolar inflammation, and decreased collagen deposition than control mice. Fibrotic proteins, including vimentin, α-SMA, collagens I and III, and the differentiation-related protein S100 calcium-binding protein A4 was reduced considerably in the hucMSCs-treated group. The mechanistic study revealed that the inhibition of hucMSCs treatment on pulmonary fibrogenesis depended on downregulating circFOXP1, in which hucMSCs treatment promoted circFOXP1-mediated autophagy process via blocking the nuclear human antigen R (HuR) translocation and promoting the HuR degradation, leading to a marked decrease in autophagy negative regulators EZH2, STAT1, and FOXK1. In conclusion, hucMSCs treatment significantly improved pulmonary fibrosis by downregulating the circFOXP1-HuR-EZH2/STAT1/FOXK1 autophagic axis. hucMSCs can act as an effective treatment for pulmonary fibrosis.

Abstract
BACKGROUND Circular RNAs (circRNAs) can have a critical function in the multi-processes of osteosarcoma (OS). Nevertheless, whether circUSP48 is involved in OS progression remains unclear. METHODS In the current work, the expression of circUSP48, miR-335 and SNIP1 in OS cell lines and tissues were evaluated using qRT-PCR. Then, Sanger sequencing, RNase R treatment and FISH assay were performed for circUSP48 validation. Furthermore, the function and potential mechanisms of circUSP48 in OS were investigated by performing loss-of-function experiments. RESULTS Silencing circUSP48 could suppress proliferation, invasion as well as migration of OS cells in vitro, also inhibiting the growth of tumor in vivo. Importantly, circUSP48 promoted OS malignancy by sponging miR-335 to upregulate SNIP1. CONCLUSION Overall, these findings suggested that circUSP48 acted as an oncogene in OS, which might become a new target for OS therapy.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease, associated with an outcome of hepatic fibrosis/cirrhosis and hepatocellular carcinoma. However, limited exploration of the underlying mechanisms hinders its prevention and treatment. To investigate the mechanisms of epigenetic regulation in NAFLD, the expression profile of circular RNA (circRNA) of rodents in which NAFLD was induced by a high-fat, high-cholesterol (HFHC) diet was studied. Modeling of the circRNA-microRNA (miRNA) -mRNA regulatory network revealed the functional characteristics of NAFLD-specific circRNAs. The targets and effects in the liver of such NAFLD-specific circRNAs were further assessed. Our results uncovered that the downregulation of 28 annotated circRNAs characterizes HFHC diet-induced NAFLD. Among the downregulated circRNAs, long intergenic non-protein coding RNA, P53 induced transcript (LNCPINT) -derived circRNAs (circ_0001452, circ_0001453, and circ_0001454) targeted both miR-466i-3p and miR-669c-3p. Their deficiency in NAFLD abrogated the circRNA-based inhibitory effect on both miRNAs, which further inactivated the AMPK signaling pathway via AMPK-α1 suppression. Inhibition of the AMPK signaling pathway promotes hepatic steatosis, depending on the transcriptional and translational upregulation of lipogenic genes, such as those encoding sterol regulatory element-binding protein 1 (SREBP1) and fatty acid synthase (FASN) in hepatocytes. The levels of LNCPINT-derived circRNAs displayed a negative association with hepatic triglyceride (TG) concentration. These findings suggest that loss of LNCPINT-derived circRNAs may underlie NAFLD via miR-466i-3p- and miR-669c-3p-dependent inactivation of the AMPK signaling pathway.

Abstract
Postnatal immune activation (PIA) can affect normal brain development and increase the risk of behavioral abnormalities in later life, including depressive-like behavior. Therefore, there is an urgent need to find safe and effective clinical medications for PIA. Recently, the protective effect of astilbin (ASB) in nervous system diseases has attracted much attention. However, the effect of ASB on neurodevelopmental diseases remains unclear. In this study, we used a lipopolysaccharide (LPS)-induced PIA mouse model and found that ASB specifically improved PIA-induced depressive-like behavior but not anxiety-like behavior in adult mice. Astrocytes play an essential role in regulating neuroinflammation, and are the most abundant cell type in the brain. In the PIA model, we found that ASB selectively inhibited astrocyte activation but not microglial activation in the cortex and hippocampus. Moreover, our results showed that ASB specifically upregulated the expression of menin protein in astrocytes and blocked the entry of P65 protein into the nucleus, thus inhibiting the secretion of IL-1β and TNF-α by astrocytes. Taken together, ASB reduced the occurrence of astrocyte-mediated neuroinflammation by targeting menin, thereby attenuating the PIA-induced depressive-like behavior. Our results reveal that ASB may be an attractive antidepressant drug and exert an antidepressant effect in PIA. In terms of drug selection, ASB may be a specific drug for patients with depressive symptoms.

Abstract
Increasing circular RNAs (circRNAs) are involved in the progression of idiopathic pulmonary fibrosis (IPF). However, circRNA biogenesis and circRNA-mediated crosstalk between mechanical stiffness and biochemical signals in IPF remain obscure. In this study, a novel circRNA-ANKRD42 from peripheral blood of patients with IPF, which participated in pulmonary fibrosis through the close communication of mechanical stiffness and biochemical signals, was identified. Mechanistic studies revealed that the heterogeneous nuclear ribonucleoprotein L (hnRNP L) activated the circANKRD42 reverse splicing biogenesis. The biogenetic circANKRD42 sponged miR-324-5p to promote the AJUBA expression, which blocked the binding between phosphorylated yes-associated protein 1 (YAP1) and large tumor suppressor kinase 1/2 (LATS1/2), leading to increased YAP1 entering the nucleus. circANKRD42 also sponged miR-136-5p to promote the YAP1 translation. Accumulating YAP1 in nucleus bound to TEAD, which initiated the transcription of genes related to mechanical stiffness. Finally, the therapeutic effect of circANKRD42 was evaluated in mice and the association between circANKRD42 and clinicopathological features was analyzed in IPF patients. Our findings supported that circANKRD42 is a promising biomarker and a potential therapeutic target related to cytoskeleton tension for IPF treatment.

Front Cell Dev Biol 2021; 9:714601.

Abstract
Objective: An increasing number of studies have demonstrated that circular RNAs (circRNAs) are involved in tumor progression. However, the role of hsa_circ_0000073 in osteosarcoma (OS) is still not fully elucidated. Methods: Quantitative reverse transcription-polymerase chain reaction or Western blot was used to detect the gene expression. GeneChip analysis, bioinformatics, luciferase reporter, and RNA immunoprecipitation assays were adopted to predict and verify the relationships between genes. Counting Kit-8 Assay, clone formation assay, wound-healing assay, transwell assays, cell cycle assays, and in vivo tumorigenesis were used to evaluate cell function. Results: hsa_circ_0000073 was highly expressed in OS cell lines and could promote OS progression, including proliferation, migration, invasion, and cell cycle in vitro as well as tumorigenesis in vivo. Mechanically, hsa_circ_0000073 could readily downregulate the expression of CCNE2 and MDM2 through miR-1252-5p. Rescue experiments validated miR-1252-5p mimics, or CCNE2/MDM2 short hairpin RNA could reverse the hsa_circ_0000073 overexpressing-induced impairment of malignant tumor behavior. Conclusion: hsa_circ_0000073 functions as a tumor promoter in OS to increase malignant tumor behavior through sponging miR-1252-5p and regulating CCNE2 and MDM2 expression, which could be a novel target for OS therapy.

[PMID: 34364922 DOI: 10.1016/j.tox.2021.152891] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Revised: 07/28/2021] [Accepted: 08/04/2021] [Indexed: 01/26/2023]
Abstract
Paraquat (PQ) poisoning induces epithelial-mesenchymal transition (EMT) in the lungs, resulting in pulmonary fibrosis with a poor prognosis. Although competitive endogenous RNA (ceRNA) networks are known to exert post-transcriptional regulatory effects, the roles of such networks in PQ-induced EMT remain unknown. We explored the potential ceRNA network involved in PQ-induced pulmonary EMT. The male BALB/c mice were injected with 10 mg/kg PQ intraperitoneally and the lungs were harvested at 21st day. The A549 cells were treated with 60 μmol/L PQ for 6 days. We determined the expression level of epithelia cadherin (E-cadherin) and α-smooth muscle actin (α-SMA) in the lungs and A549 cells after PQ exposure. We also detected the expression level of the long noncoding RNA (lncRNA) HOX transcript antisense intergenic RNA (HOTAIR), microRNA-17-5p (miR-17-5p), and matrix metalloproteinase 2 (MMP2). We used specific siRNA to determine the influence of HOTAIR on MMP2. We also transfected a mimic or inhibitor of miR-17-5p to explore its role. Moreover, we used the luciferase reporter gene assay to confirm the relationship between miR-17-5p and HOTAIR or MMP2. In this study, we found that MMP2 and HOTAIR were upregulated and miR-17-5p was downregulated in PQ-induced EMT. The knockdown of HOTAIR decreased the expression of MMP2, and the upregulation of miR-17-5p suppressed HOTAIR and MMP2. Apparently, the downregulation of miR-17-5p increased the expression of HOTAIR and MMP2. The expression of α-SMA was negatively regulated by miR-17-5p after PQ exposure. In addition, the luciferase reporter gene assay confirmed that HOTAIR and MMP2 had direct binding sites with miR-17-5p. In conclusion, this study showed that the HOTAIR could act as a ceRNA for miR-17-5p to regulate MMP2 expression in PQ-induced pulmonary EMT.

Abstract
Spinal cord injury (SCI) may cause long-term physical impairment and bring a substantial burden to both the individual patient and society. Existing therapeutic approaches for SCI have proven inadequate. This is mainly owing to the incomplete understanding of the cellular and molecular events post-injury. Circular RNAs (circRNAs) represent a new class of non-coding RNAs with a covalently closed annular structure that participates in regulating the transcription of certain genes and are linked to various biological processes and diseases. Mounting evidence is indicative that circRNAs are highly expressed in the spinal cord and they play key roles in multiple processes of neurological diseases. Recently, a role for circRNAs as effectors of SCI has emerged, leading to the continuity of relevant research. In this review, we presented current studies with regards to the abnormality of circRNAs mediating SCI by affecting mechanisms of autophagy, apoptosis, inflammation, and neural regeneration. Furthermore, the potential clinical value of circRNAs as therapeutic targets of SCI was also analyzed.

J Cell Mol Med 2021; 25:7294-7306.

Abstract
Dysregulation of non‐coding RNAs (ncRNAs) has been proved to play pivotal roles in epithelial‐mesenchymal transition (EMT) and fibrosis. We have previously demonstrated the crucial function of long non‐coding RNA (lncRNA) ATB in silica‐induced pulmonary fibrosis‐related EMT progression. However, the underlying molecular mechanism has not been fully elucidated. Here, we verified miR‐29b‐2‐5p and miR‐34c‐3p as two vital downstream targets of lncRNA‐ATB. As opposed to lncRNA‐ATB, a significant reduction of both miR‐29b‐2‐5p and miR‐34c‐3p was observed in lung epithelial cells treated with TGF‐β1 and a murine silicosis model. Overexpression miR‐29b‐2‐5p or miR‐34c‐3p inhibited EMT process and abrogated the pro‐fibrotic effects of lncRNA‐ATB in vitro. Further, the ectopic expression of miR‐29b‐2‐5p and miR‐34c‐3p with chemotherapy attenuated silica‐induced pulmonary fibrosis in vivo. Mechanistically, TGF‐β1‐induced lncRNA‐ATB accelerated EMT as a sponge of miR‐29b‐2‐5p and miR‐34c‐3p and shared miRNA response elements with MEKK2 and NOTCH2, thus relieving these two molecules from miRNA‐mediated translational repression. Interestingly, the co‐transfection of miR‐29b‐2‐5p and miR‐34c‐3p showed a synergistic suppression effect on EMT in vitro. Furthermore, the co‐expression of these two miRNAs by using adeno‐associated virus (AAV) better alleviated silica‐induced fibrogenesis than single miRNA. Approaches aiming at lncRNA‐ATB and its downstream effectors may represent new effective therapeutic strategies in pulmonary fibrosis.

Cancer Manag Res 2021; 13:4251-4262.

Abstract
There are few biomarkers available for the early diagnosis and prognostic evaluation of pancreatic cancer. In addition, the development of targeted therapy for pancreatic cancer is an unmet need due to the lack of molecular targets. With the continuous progress in circular RNA (circRNA)-related research, its role in the occurrence and development of pancreatic cancer has been discovered and gradually recognized. Therefore, circRNA may represent a novel marker for early diagnosis of this disease and a focus of targeted clinical therapy. CircRNA is a type of non-coding RNA with a closed circular structure formed by covalent bonds. Some circRNAs can act as “sponges” to adsorb microRNAs (miRNAs) and play the role of competitive endogenous RNA (ceRNA) to remove their inhibitory effects on the target genes of miRNA. Thus, they can indirectly restore the expression of target genes. The circRNA–miRNA–mRNA network plays a regulatory role in the proliferation, invasion, metastasis, and other biological behaviors of pancreatic cancer. Given the recent advances in circRNA, this review seeks to provide an overview of the biological function of circRNA and highlights the recent research progress regarding the molecular mechanism of circRNA for the clinical diagnosis and treatment of pancreatic cancer.

Abstract
BACKGROUND Hepatic fibrosis is an inflammatory liver disease, and there is no effective therapy at present. Astilbin is a bioactive ingredient found in many medicinal and food plants, with antioxidative, anti-inflammatory, and antitumor properties. OBJECTIVES This study aimed to investigate the protective effect and related molecular mechanism of astilbin against carbon tetrachloride (CCl4)-induced liver fibrosis in rats. METHODS Liver fibrosis was induced by injection of CCl4 in male Sprague-Dawley rats, and those rats were then treated with astilbin at different concentrations. Pathological changes, collagen production, inflammatory cytokine, and oxidative stress were evaluated to evaluate the effects of astilbin on CCl4-induced hepatic fibrosis. Real-time PCR and western blot were performed to detect the mRNA and protein expression of indicated genes. RESULTS We discovered that CCl4 caused significant fibrosis damage in rat liver, and astilbin dose-dependently improved the liver functions and fibrosis degree. Astilbin treatment significantly decreased collagen production, inflammatory response, and oxidative stress in vivo. Mechanically, administration of astilbin obviously elevated the hepatic levels of Nrf2 and its downstream components, including NAD(P)H:quinone oxidoreductase 1 (Nqo1), heme oxygenase (HO-1), glutamate-cysteine ligase catalytic subunit, and glutamate cysteine ligase modifier. CONCLUSIONS Taken together, these findings demonstrate that astilbin could protect against CCL4 induced-liver fibrosis in rats.

Abstract
Osteosarcoma (OS) is the most frequently occurring bone cancer. Circular RNAs (circRNAs) have been shown to exert pivotal impact in modulation of gene expression, but their roles in OS are still not fully understood. In this study, we analysed the role of circ‐0000658 in OS. Thereafter, molecular techniques such as Western blot, qRT‐PCR, RNA‐binding protein immunoprecipitation and Dual‐Luciferase reporter assays were implemented to investigate the role of circ‐0000658/miR‐1227/interferon regulatory factor‐2 (IRF2) axis in OS. Eventually, the impact of circ‐0000658 on tumour growth and metastasis was observed in a xenograft mouse model. The results of this study revealed that circ‐0000658 exhibits low levels in OS tissues and cell lines. Moreover, circ‐0000658 repression promoted cell cycle, proliferation, invasion and migration but inhibited the apoptosis of OS cells. Researches have previously shown that circ‐0000658 contains a binding site for miR‐1227 and thus can abundantly sponge miR‐1227 to up‐regulate the expression of its target gene IRF2. Moreover, both inhibition of miR‐1227 and overexpression of IRF2 reversed cell proliferation and invasion, which was triggered by circ‐0000658 repression. Conclusively, circ‐0000658 modulates biological function of OS cells through the miR‐1227/IRF2 axis. Therefore, circ‐0000658 might act as a possible novel therapeutic target for the treatment of OS.

Abstract
PURPOSE The prognosis of AML patients with chemotherapy is poor, especially those who are insensitive to and resistant to chemotherapy drugs. To clarify the underlying pathogenesis of AML and provide new therapeutic targets for clinical treatment, we explore the role of circRNA in leukemia. METHODS High-throughput circRNA sequencing analysis was performed in patients with leukemia and healthy donors. RT-qPCR and western blot analysis were used to determine expression of GSK3β. RNA pull-down assay was used to detect miRNAs pulled down by hsa_circ_0121582. RNA immunoprecipitation assay was performed to evaluate the binding capacity between TET1 and hsa_circ_0121582. RESULTS A new and highly stable circRNA was found, which was derived from the reverse splicing of GSK3β exon 1 to exon 7, and hsa_circ_0121582 was down-regulated in leukemia cells. In gain-of-function experiments, the up-regulated hsa_circ_0121582 inhibited the proliferation of leukemia cells in vitro and in vivo. In the cytoplasm, hsa_circ_0121582 could act as a sponge for miR-224, attenuate the inhibiting effect of miR-224 on GSK3β, and thus up-regulate the expression level of GSK3β. In addition, hsa_circ_0121582 could bind to GSK3β promoter in the nucleus, and recruit DNA demethylase TET1 to ensuring the transcription of GSK3β. The upregulated GSK3β inhibited the Wnt/β-catenin signaling pathway, and reduced the aggregation of β-catenin in the nucleus, thus inhibited the proliferation of leukemia cells. CONCLUSIONS This study found that hsa_circ_0121582 was involved in the inhibition of tumor proliferation, and the restoration of hsa_circ_0121582 could be an effective treatment strategy for patients with leukemia.

Abstract
Circular RNAs (circRNAs) are becoming new therapeutic drug targets. However, their profiles under astilbin treatment have not been reported yet. In this study, we analysed the global reprogramming of circRNA transcriptome and a regulatory network of circRNAs with their targeted genes under astilbin treatment in pulmonary fibrosis. A total of 145 circRNAs were differentially expressed in the astilbin-treated group compared with the bleomycin-treated group using RNA sequencing. In the bleomycin- and astilbin-treated groups, 29 coexpressed circRNAs were found. The maximum number of circRNAs was distributed on chromosome two, and their length varieties were mainly within 1000 bp. Four differentially expressed circRNAs (circRNA-662, 949, 394 and 986) were tested to validate the RNA sequencing data, and their targeted microRNAs and genes were analysed by qRT-PCR, Western blot, Pearson correlation coefficient, a dual-luciferase reporter system and anti-AGO2 RNA immunoprecipitation. The results showed that circRNA-662 and 949 can act as "miR-29b sponges" targeting Gli2 and STAT3 to exert their functions. Our work suggests that the transcriptome complexity at the circRNA level under astilbin treatment. These circRNAs may be potential molecular targets for drug action.
