Abstract
Breast cancer (BC) is one of the most common malignant tumors in women. CircRNA/miRNA/mRNA regulatory axes have been shown to be involved in the pathogenesis of BC. Here, we sought to analyze the functional mechanism of circ_0104345 in BC. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the levels of circ_0104345, miR-876-3p and zinc finger and BTB domain containing 20 (ZBTB20) mRNA. Cell Counting Kit-8 (CCK8) and 5-ethynyl-2'-deoxyuridine (EdU) assays were used to test cell viability and proliferation, respectively. Cell migration was tested by wound healing assay, and cell invasion was examined by transwell assay. Tube formation ability was tested by angiogenesis assay. Flow cytometry was applied for cell apoptosis. Western blot assay was utilized to measure the protein expression. The relationship between miR-876-3p and circ_0104345 or ZBTB20 was identified by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. Xenografts in mice were conducted to analyze the effect of sh-circ_0104345 on tumor growth in vivo. Circ_0104345 and ZBTB20 were upregulated and miR-876-3p expression was decreased in BC. Circ_0104345 knockdown inhibited cell proliferation, migration, invasion, and enhanced cell apoptosis. MiR-876-3p was targeted by circ_0104345. MiR-876-3p depletion reversed the effects of circ_0104345 downregulation on the progression of BC cells. ZBTB20 was regulated by circ_0104345 through miR-876-3p. The effects of miR-876-3p on BC cell behaviors were restored by ZBTB20 increase. The results of in vivo experiments indicated that silencing of circ_0104345 blocked the growth of xenograft tumors. In this study, we demonstrated, for the first time, the crucial regulation of the new circ_0104345/miR-876-3p/ZBTB20 axis in the biological phenotypes of BC cells.

Abstract
Temozolomide (TMZ) resistance limits its use in glioblastoma (GBM). Exosomes can carry circular RNAs (circRNAs) to regulate chemoresistance. To date, the role of exosomal hsa_circ_0043949 (circ_0043949) in GBM resistance to TMZ is unclear. Relative expression of circ_0043949 in clinical samples, GBM cell lines, and exosomes was detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The half-maximal inhibitory concentration (IC50) of TMZ, cell proliferation, apoptosis, invasion, and migration were analyzed via MTT, EdU, flow cytometry, transwell, and wound-healing assays. Relative protein levels were evaluated by western blotting. Target relationship was predicted by bioinformatics analysis and validated by dual-luciferase reporter and RNA pull-down assays. Exosomes were isolated by ultracentrifugation and verified by transmission electron microscopy, nanoparticle tracking analysis (NTA), and western blotting. The effect of exosomal circ_0043949 on TMZ resistance was validated by xenograft assay. Higher expression of circ_0043949 was gained in TMZ-resistant GBM samples and cells. Inhibition of circ_0043949 reduced TMZ resistance via decreasing IC50 of TMZ, repressing proliferation, invasion, migration, and inducing apoptosis in TMZ-resistant GBM cells. Circ_0043949 mediated integrinalpha1 (ITGA1) expression via function as a miR-876-3p sponge. Circ_0043949 was also upregulated in TMZ-resistant GBM cells-derived exosomes, and exosomal circ_0043949 increased the resistance of TMZ-resistant GBM cells to TMZ in xenograft models. TMZ-resistant GBM cells-derived exosomal circ_0043949 promoted TMZ resistance via upregulating ITGA1 expression via sequestering miR-876-3p, offering a potential target for the treatment of TMZ resistance in GBM.

Abstract
BACKGROUND Acute myeloid leukemia (AML) is one of the most common malignant myeloid diseases in adults with a dismal prognosis. We aimed to explore the effects of circNFIX on the proliferation and apoptosis of AML cells. METHODS The expressions of circNFIX, miR-876-3p and tripartite motif (TRIM) 31 in the bone marrow specimens of AML patients and AML cell lines were detected by qRT-PCR or western blot. Cell proliferation was evaluated by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and 5-ethynyl-29-deoxyuridine (EdU) assays. Cell cycle and apoptosis were analyzed by flow cytometry. Western blot was used to detect protein expression. The relationship between miR-876-3p and circNFIX or TRIM31 was identified by dual-luciferase reporter assay or RNA pull-down assay. RESULTS The expression level of circNFIX was significantly increased in the bone marrow samples of AML patients and AML cells when compared with normal controls. CircNFIX silencing inhibited AML cell proliferation and promoted apoptosis. Inhibition of miR-876-3p reversed the effect of circNFIX knockdown on AML cell progression. In addition, circNFIX indirectly regulated TRIM31 through miR-876-3p. Further, TRIM31 overexpression counteracted the effect of circNFIX silencing on AML cell proliferation and apoptosis. CONCLUSION CircNFIX knockdown could suppress the proliferation and induce the apoptosis of AML cells by targeting the miR-876-3p/TRIM31 axis.

Abstract
An increasing number of findings have verified the critical roles of circular RNAs (circRNAs) in human cancers, and chemotherapy resistance is a poor prognostic factor for breast cancer (BC). This study is designed to explore the function of hsa_circ_0097922 in the tamoxifen resistance of breast cancer. Hsa_circ_0097922, microRNA-876-3p (miR-876-3p), and alpha-actinin 4 (ACTN4) level were detected by real-time quantitative polymerase chain reaction (RT-qPCR). Cell survival, proliferation, apoptosis, migration and invasion were detected by Cell Counting Kit-8 (CCK-8), 5-ethynyl-2'-deoxyuridine (EdU), and flow cytometry, wound healing and Transwell assays. Protein levels of proliferating cell nuclear antigen (PCNA), B-cell lymphoma-2 (Bcl-2), cleaved caspase 3, matrix metalloproteinase 9 (MMP9), and ACTN4 were determined using western blot assay. Using bioinformatics software, the binding between miR-876-3p and hsa_circ_0097922 or ACTN4 was predicted, followed by confirmation by RNA immunoprecipitation (RIP) and RNA pull-down assays. A xenograft tumour model in vivo analysed the biological role of hsa_circ_0097922 on BC tumour growth and drug resistance. Hsa_circ_0097922 and ACTN4 were increased, and miR-876-3p was decreased in tamoxifen resistance BC cells. Moreover, hsa_circ_0097922 knockdown can block BC cell malignant behaviour and tamoxifen resistance in vitro. Mechanically, hsa_circ_0097922 acted as a sponge of miR-876-3p to regulate ACTN4 expression. Hsa_circ_0097922 silencing increased the drug sensitivity of BC in vivo. Hsa_circ_0097922 might regulate BC cell malignant behaviour and tamoxifen resistance partly by regulating the miR-876-3p/ACTN4 axis, hinting at a promising therapeutic target for the BC treatment.

Abstract
Non-small cell lung cancer (NSCLC) is a serious threaten to human health globally. Circular RNAs (circRNAs) were testified to alter the progression of NSCLC. This work intended to investigate the functional role of circ_0016760 in NSCLC development and the potential mechanism. Expression of circ_0016760, microRNA (miR)-876-3p and NOVA alternative splicing regulator 2 (NOVA2) was determined via quantitative reverse transcription-PCT (qRT-PCR) or western blotting. Cell viability, clonogenicity and apoptosis were assessed by Cell Counting Kit-8 (CCK-8) assay, colony formation assay and flow cytometry, respectively. Transwell assay was performed to examine cell migration and invasion. Western blotting was also conducted to detect the levels of epithelial-to-mesenchymal transition (EMT)-related proteins. Role of circ_0016760 in vivo was evaluated via xenograft model assay. Moreover, the interaction between miR-876-3p and circ_0016760 or NOVA2 was verified by dual-luciferase reporter assay or RNA Immunoprecipitation (RIP) assay. Circ_0016760 and NOVA2 were upregulated, while miR-876-3p expression was decreased in NSCLC tissues and cells. Circ_0016760 depletion suppressed NSCLC cell proliferation and metastasis in vitro, as well as hampered tumor growth in vivo. Circ_0016760 acted as a sponge of miR-876-3p, and miR-876-3p could target NOVA2. Circ_0016760 might play vital roles in NSCLC by regulating miR-876-3p/NOVA2 axis. Circ_0016760 could promote the malignant development of NSCLC through miR-876-3p/NOVA2 axis, at least in part.

Abstract
BACKGROUND miR-876-3p has been identified to be downregulated in colon cancer, implying the potential biological function in the progression and prognosis of colon cancer. The clinical significance and the biological function of miR-876-3p were investigated in this study to assess the potential of miR-876-3p in acting as a novel biomarker of the progression of colon cancer. METHODS The expression of miR-876-3p in colon cancer was evaluated by RT-qPCR. The clinical significance of miR-876-3p was assessed by associated its expression level with the clinical features and prognosis of patients. The biological function of miR-876-3p was estimated by the CCK8 and Transwell assay in vitro. RESULTS The significant downregulation of miR-876-3p was observed in colon cancer tissues and cells, which was closely associated with the lymph node metastasis status, TNM stage, and the perineural invasion of patients. miR-876-3p served as an independent indicator that was negatively associated with the prognosis of patients. In colon cancer cells, miR-876-3p showed significant inhibitory effects on cell proliferation, migration, and invasion, indicating its tumor suppressor role in the progression of colon cancer. CONCLUSION miR-876-3p might be involved in colon cancer development, which provides a potential therapeutic target for colon cancer treatment.

Abstract
CircRNA LNPEP has been shown to promote the development of hepatocellular carcinoma, but its function in ovarian cancer (OC) remains unclear. The Kaplan–Meier method was used to analyze the clinical significance of circLNPEP expression in OC patients. The stability of circLNPEP was detected by actinomycin D and RNase R treatment. The correlations between miR-876-3p and two genes (circLNPEP and WNT5A) were predicted by bioinformatics analysis and confirmed by dual-luciferase reporter assay. Expressions of circLNPEP, miR-876-3p, and WNT5A were determined by qRT-PCR and western blot. The effect of circLNPEP/miR-876-3p/WNT5A axis on viability, proliferation, migration, and invasion, and angiogenesis of cells was determined by cell function experiment and rescue experiment. Xenograft tumor mice were constructed for in vivo verification. Expressions of apoptosis, epithelial mesenchymal transition (EMT)-related genes, and CD34 were determined by qRT-PCR, western blot and immunohistochemistry. High level of circLNPEP was related to poor prognosis in OC. CircLNPEP was highly expressed in OC tissues and cell lines, mainly distributed in the cytoplasm, while miR-876-3p was the opposite. MiR-876-3p targeted and negatively correlated with circLNPEP and WNT5A. Sh-circLNPEP repressed cell viability, proliferation, migration, invasion, angiogenesis, and EMT but promoted apoptosis, which were related to its regulation of expression of EMT- and apoptosis-related genes, WNT5A, and CD34. The regulatory effect of sh-circLNPEP can be reversed by miR-876-3p inhibitor, and that of miR-876-3p inhibitor can be reversed by sh-WNT5A. CircLNPEP promoted cancer cell proliferation, EMT and angiogenesis, and inhibited apoptosis by regulating miR-876-3p/WNT5A axis.

Abstract
Background The aberrant expression of circular RNAs (circRNAs) plays vital roles in the advancement of human cancers, including gastric cancer (GC). In this study, the functions of circRNA ring finger protein 111 (circ-RNF111) in GC were investigated. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) assay was performed for the levels of circ-RNF111, microRNA-876-3p (miR-876-3p) and krueppel-like factor 12 (KLF12) mRNA. RNase R assay was conducted for the feature of circ-RNF111. Cell Counting Kit-8 (CCK-8) assay, colony formation assay, wound-healing assay, and transwell assay were applied for cell viability, colony formation, migration, and invasion, respectively. Flow cytometry analysis was used to analyze cell apoptosis and cell cycle process. The glycolysis level was examined using specific commercial kits. Western blot assay was carried out to measure the protein levels of hexokinase 2 (HK-2) and KLF12. Dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were employed to verify the combination between miR-876-3p and circ-RNF111 or KLF12. Murine xenograft model was constructed for the role of circ-RNF111 in vivo. Immunohistochemistry (IHC) was used for KLF12 level. Results Circ-RNF111 was higher expressed in GC tissues and cells than normal tissues and cells. Silencing of circ-RNF111 restrained cell viability, colony formation, migration, invasion, cell cycle process and glycolysis and induced apoptosis in GC cells in vitro. Circ-RNF111 positively regulated KLF12 expression via absorbing miR-876-3p. MiR-876-3p downregulation reversed the impacts of circ-RNF111 silencing on GC cell malignant phenotypes. MiR-876-3p overexpression repressed GC cell growth, metastasis and glycolysis, inhibited apoptosis and arrested cell cycle, while KLF12 elevation weakened the effects. Besides, circ-RNF111 knockdown inhibited tumor growth in vivo. Conclusion Circ-RNF111 knockdown relieved the development of GC by regulating miR-876-3p/KLF12 axis.

Abstract
Circular RNAs (circRNAs) are widely expressed in mammals and act as regulatory targets in the atherogenesis. The objective of this study was to research the biological role and molecular mechanism of circ_0093887 in oxidized low-density lipoprotein (ox-LDL)-induced atherosclerosis (AS) of human aortic endothelial cells (HAECs). Cell viability detection was performed by CCK-8 assay. Inflammatory molecules were examined using ELISA. Flow cytometry was used to measure cell-cycle progression and cell apoptotic rate. Caspase 3 activity was determined using caspase 3 activity assay. The expression levels of circ_0093887, miR-876-3p, CCND2 and SUCNR1 were assayed by quantitative real-time polymerase chain reaction (qRT-PCR). Dual-luciferase reporter, RNA immunoprecipitation (RIP) and RNA pull-down assays were used for the target analysis. EdU assay, wound healing assay/transwell assay and tube formation assay were, respectively, used to assess the effects of circ_0093887/miR-876-3p axis on cell proliferation, migration and tube formation. Oxidized low-density lipoprotein inhibited cell viability and cell-cycle progression but induced the inflammatory response and cell apoptosis. Circ_0093887 was downregulated and miR-876-3p was upregulated in AS patients and ox-LDL-treated HAECs. Functionally, the overexpression of circ_0093887 abrogated the cell injury of HAEC exposed to ox-LDL. For the functional mechanism, we found that circ_0093887 was a sponge for miR-876-3p and miR-876 targeted CCND2 or SUCNR1. The reverted experiment indicated that the function of circ_0093887 was achieved by sponging miR-876-3p. Meanwhile, miR-876-3p inhibitor relieved the inhibitory regulation of circ_0093887 knockdown in cell proliferation, migration and tube formation. Downregulation of miR-876-3p also alleviated the ox-LDL-induced cell injury by upregulating the expression of CCND2 or SUCNR1. Furthermore, circ_0093887 was validated to regulate the levels of CCND2 and SUCNR1 via the sponge effect on miR-876-3p. The protective effects of circ_0093887 on HAECs from ox-LDL were also alleviated by repressing the CCND2 and SUCNR1 levels. These findings suggested that circ_0093887 protected HAEC against the ox-LDL-induced inflammatory and apoptotic damages by targeting the miR-876-3p/CCND2 or miR-876/SUCNRA axis. Circ_0093887 could act as a potential therapeutic biomarker for AS patients.

Abstract
INTRODUCTION Acute lymphocytic leukemia (ALL) is a hematologic malignancy caused by the clonal proliferation of immature lymphocytes. Long noncoding RNAs (lncRNAs) have been reported as critical regulators in several cancers, including ALL. LncRNA SLCO4A1 antisense RNA 1 (SLCO4A1-AS1) has been revealed to be implicated in tumorigenesis of several cancers. Our study focused on the role of SLCO4A1-AS1 in ALL. METHODS RT-qPCR, Western blot analysis, CCK-8, EdU, and Flow cytometry analysis were used to explore the biological function of SLCO4A1-AS1 in ALL cellular processes. Luciferase reporter and RNA pull-down assays were applied to explore the mechanism of SLCO4A1-AS1 in ALL cells. RESULTS SLCO4A1-AS1 was upregulated in ALL tissues and cell lines. We found that suppression of SLCO4A1-AS1 suppressed ALL cell proliferation and facilitated cell apoptosis. Our result confirmed that SLCO4A1-AS1 acted as a ceRNA by sponging microRNA 876-3p (miR-876-3p) to upregulate retinoblastoma binding protein 6 (RBBP6) expression in ALL cells. Moreover, SLCO4A1-AS1 activated the JNK signaling pathway by upregulating RBBP6. Rescue assays revealed that the activation of the JNK signaling or overexpression of RBBP6 revered the suppressive effect of SLCO4A1-AS1 knockdown on growth of ALL cells. CONCLUSION SLCO4A1-AS1 promoted cell growth of ALL by the miR-876-3p/RBBP6 axis to activate the JNK signaling pathway.

Abstract
Recently, growing studies have demonstrated that circular RNAs (circRNAs) function as critical players in multiple human tumors, including papillary thyroid carcinoma (PTC). However, the expression and underlying potential mechanism of circRNAs in PTC are still not fully elucidated. In this study, 14 candidate differentially expressed circRNAs (DECs) between normal thyroid tissues and benign thyroid tissues or PTC were first screened using the GSE93522 dataset by the GEO2R online tool. Then, the structural loop graphs of these 14 circRNAs were obtained through the CSCD database. After performing miRNA co-prediction by combination of CSCD and CRI databases, a potential circRNA-miRNA sub-network, consisting of 9 circRNAs and 21 miRNAs, was successfully constructed. Subsequently, the expression and prognostic values of these miRNAs were further determined by starBase, and two miRNAs, namely, miR-605-5p and miR-876-3p, were identified as key miRNAs in PTC. Then, their downstream target genes were predicted by the miRNet database. CTNNB1 and CCND1 were found to be two most potential targets of miR-876-3p by combination of multiple in silico analyses, including protein–protein interaction (PPI), hub gene screening, correlation analysis, and expression analysis. Conclusively, we established a key hsa_circ_0088494-miR-876-3p-CTNNB1/CCND1 axis linked to carcinogenesis and progression of PTC, which may provide promising therapeutic targets in treating PTC in the future.

Abstract
According to ceRNA theory, circular RNAs could regulate certain protein expression through targeting corresponding microRNAs to affect the progression of multiple diseases, including colorectal cancer. CircTP53 (hsa_circ_0107702), highly expressed in thyroid cancer tissues, could promote the proliferation of thyroid cancer. However, the function of circTP53 in colorectal cancer is still unclear. In our study, we found circTP53 was significantly up-regulated in colorectal cancer tissues from patients and in colorectal cell lines. Next, using colorectal cell lines, we confirmed that circTP53 promoted the proliferation, migration and invasion, and reduced the apoptotic rate. Furthermore, through bioinformatics analysis and experimental confirmation, we found circTP53 functioned as the sponge of miR-876-3p, and miR-876-3p reversed the phenotype of circTP53 on the facilitation of colorectal cancer. Additionally, we found circTP53 promoted the progression of colorectal cancer by elevating the expression of CDKL3. At last, we suggested that circTP53 knockdown could inhibit colorectal cancer progression in vivo. In conclusion, circTP53 was highly expressed in colorectal cancer tissues, and promoted colorectal cancer progression via modulating miR-876-3p/CDKL3 axis.

Abstract
Background SPRR3, also known as esophagin, has been shown to be involved in the initiation and progression of numerous types of tumor. However, the biological function of SPRR3 that contributes to non-small-cell lung cancer (NSCLC) growth and migration is largely unknown. Methods The expression of SPRR3 and its association with EZH2 and miR-876-3p in NSCLC cells were determined by real-time PCR. Protein levels were measured by immunohistochemistry (IHC) and Western blot. Cell functions were studied by CCK-8, transwell assay, flow cytometry and dual-luciferase reporter assay. The effect of SPRR3 on tumor growth in vivo was evaluated in patient-derived xenograft (PDX) models. Results SPRR3 was up-regulated in most NSCLC cell lines and clinical tissues. Also, the correlation between SPRR3 expression and clinical features was significant. Functional studies confirmed that SPRR3 modulates cell proliferation, invasion and cell apoptosis in NSCLC via regulating EZH2, which is a well-known oncogene in NSCLC. Furthermore, SPRR3 was found to be a direct target of miR-876-3p that also plays a suppressor role in NSCLC. Conclusion These findings indicated that miR-876-3p/SPRR3/EZH2 signaling cascade exerts important roles in the regulation of NSCLC, suggesting that this pathway can serve as a potential therapeutic target in NSCLC.

Abstract
BACKGROUND AND AIM Gastric cancer (GC), a prevalent tumor, exerts a major economic burden, and we aimed to explore miR-876-3p's effects on GC and related mechanisms. METHODS Cell viability was analyzed via CCK-8 and colony formation assay. Stem cell-like properties were examined via spheroid colony formation assay. mRNA abundance of key genes was analyzed via quantitative polymerase chain reaction. Protein level of TMED3 and stem cell markers was examined by western blot. TargetScan, luciferase, and biotin-miRNA pulldown assay were used to identify miR-876-3p's target. RESULTS MiR-876-3p was downregulated in GC, and its mRNA level had negative relationship with cisplatin resistance of GC. Moreover, decreased miR-876-3p expression level suggested poor prognosis of GC patients. MiR-876-3p inhibited drug resistance of cisplatin-resistant cell line SGC-7901/DDP and MKN-45/DDP, as shown by decreased cell viability, IC50 , and colony formation ability. MiR-876-3p inhibited stem cell-like features and downregulated the expressions of Sox-2, Oct-4, CD133, and CD44 in GC cells. Luciferase and biotin-miRNA pulldown assay confirmed that TMED3 was miR-876-3p's direct target. TMED3 siRNA inhibited miR-876-3p's effects on cisplatin resistance and stem cell-like features of SGC-7901/DDP cells. CONCLUSION MiR-876-3p enhanced cisplatin sensitivity and restricted stem cell-like features of GC through targeting TMED3.

Abstract
Aberrant expression of miRNAs has been reported to be involved in the development and progression of glioma. But the function of miR-876-3p in glioma is unknown. We found that miR-876-3p is significantly downregulated in glioma tissues and cell lines. Overexpression of miR-876-3p suppressed glioma cell proliferation, epithelial-mesenchymal transition, migration, and invasion. By prediction combining with luciferase reporter assay, we identified that miR-876-3p could decrease the expression of KIF20A by directly targeting the region of its 3'UTR. Furthermore, we observed that overexpression of miR-876-3p inhibited the expression of KIF20A, thus blocking the protein kinase JAK2/STAT3 pathway. Overexpressed KIF20A reversed miR-876-3p-induced suppression of glioma cell proliferation, migration, and invasion. We also demonstrated the inhibitory effect of miR-876-3p on tumor growth in glioma using an in vivo model. The miR-876-3p/KIF20A-axis mediated JAK2/STAT3 pathway have therapeutic potential in glioma treatment.

Abstract
Dysregulation of microRNA (miRNA) expression in multiple cancers and their vital roles in malignant cancer progression are well investigated. The purpose of this study was to explore the biological roles of miR-876-3p in pancreatic cancer. We used genome-wide gene expression analysis in clinical pancreatic adenocarcinoma samples to identify miR-876-3p down-regulated in pancreatic cancer. We then collected 22 pairs of pancreatic cancer and the corresponding non-cancerous tissues to determine miR-876-3p level, and confirmed that miR-876-3p was significantly down-regulated in pancreatic cancer. Furthermore, functional analysis suggested that overexpression of miR-876-3p suppressed cell growth and aggressively increased cells apoptosis in BXPC-3 and PANC-1 cells, whereas down-regulation led to the opposite results. We identified Jagged2 (JAG2) as a direct target of miR-876-3p, and an inverse correlation between miR-876-3p and JAG2 was observed in pancreatic adenocarcinoma. Moreover, miR-876-3p and a JAG2 siRNA were co-transfected into both PANC-1 and BXPC-3 cells to explore the mechanism of miR-876-3p and JAG2 on pancreatic adenocarcinoma tumorigenesis. Down-regulation of JAG2 inhibited the overexpression effects of miR-876-3p, and up-regulation of JAG2 reversed the effects of overexpressed miR-876-3p. Cumulatively, these results revealed a significant role of the miR-876-3p/JAG2 axis in suppressing pancreatic adenocarcinoma cell growth and aggressiveness.
