Abstract
Introduction Hepatocellular carcinoma (HCC) as the malignant cancers with high morbidity. The EMT of HCC has closely linked to the metastasis and recurrence. Moreover, tumor-associated macrophages (TAMs) can interact with HCC cells in the immune microenvironment; the M2 polarization of TAMs enhance the HCC cells EMT. The mechanism between HCC cells and TAMs is still unclear and our study was aimed to uncover it. Methods We performed RT-qPCR and western to detach the RNA and protein expression. The relationship among has_circ_0000092, U2AF2, SMC1A and IL24 were revealed through mechanism experiments. Rescue assays were implemented to determine how circ_0000092 modulates M2 polarization of TAMs. Results As detected by RT-qPCR, has_circ_0000092 was with high expression in HCC cells and could recruit U2AF2 to promote transcription of SMC1A. Moreover, circ_0000092 could control macrophage M2 polarization via promoting IL24 expression in HCC cells. Conclusion To conclude, hsa_circ_0000092 can up-regulates IL24 by SMC1A to induce macrophages M2 polarization.

Abstract
Circular RNA (circRNA) plays important role in hepatocellular carcinoma (HCC) progression. However, the role and mechanism of circETV6 in HCC progression remain unclear. The levels of circETV6, ETV6, miR-383-5p, and PTPRE were tested by quantitative reverse-transcription polymerase chain reaction. Cell functions were assessed using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay, 5-ethynyl-2'-deoxyuridine assay, colony formation assay, wound healing assay, transwell assay, and flow cytometry. The protein levels of poptosis-related markers and PTPRE were determined by western blot analysis. RNA interaction was analyzed by dual-luciferase reporter assay and RNA pull-down assay. A xenograft model was established to assess circETV6 roles in vivo. CircETV6 was highly expressed in HCC tissues and cells. CircETV6 knockdown repressed HCC cell proliferation, migration, invasion, and cell cycle, while accelerated apoptosis. CircETV6 targeted miR-383-5p, and miR-383-5p inhibition reversed the regulation of circETV6 knockdown on HCC cell progression. CircETV6 promoted PTPRE level via targeting miR-383-5p. Overexpressed PTPRE abolished the inhibition effect of miR-383-5p on HCC cell progression. In addition, circETV6 knockdown slowed HCC tumor growth in vivo. CircETV6 might facilitate HCC progression via the miR-383-5p/PTPRE axis, providing a novel target for HCC treatment.

Abstract
Lung adenocarcinoma (LUAD) is the most common subtypes of NSCLC. However, the therapeutic effects for LUAD are unsatisfactory at current stage, so it is important to find new molecular targets and therapeutic strategies. circRNAs can regulate the expression of target genes by binding to microRNAs (miRNAs) to form competitive endogenous RNAs (ceRNAs). Therefore, we investigated the functions of circR-4225 in the tumor progression of LUAD and its molecular mechanism in this paper. circR-4225 is up-regulated in LUAD tissues. EIF4A3, a member of the eukaryotic translation initiation factor 4A (EIF4A) family, promotes the expression of circR-4225. circR-4225 acts as a molecular sponge to down-regulate miR-507, which promotes the up-regulation of the expression of its target gene-tumor necrosis factor superfamily member 11 (TNFSF11). Knockdown of circR-4225 in the LUAD cell lines can inhibit cell proliferation and viability, and promote apoptosis of the LUAD cell lines, which can be reverted by inhibiting miR-507 or overexpressing TNFSF11. To sum it up, this study demonstrated that circR-4225 was significantly up-regulated in LUAD tissues, and circR-4225 promoted LUAD progression by sponging miR-507 and up-regulating TNFSF11. This study can provide new molecular targets for early diagnosis and treatment of LUAD.

Abstract
Cell immortalization, a hallmark of cancer development, is a process that cells can undergo on their path to carcinogenesis. Spontaneously immortalized mouse embryonic fibroblasts (MEFs) have been used for decades; however, changes in the global transcriptome during this process have been poorly described. In our research, we characterized the poly-A RNA transcriptome changes after spontaneous immortalization. To this end, differentially expressed genes (DEGs) were screened using DESeq2 and characterized by gene ontology enrichment analysis and protein-protein interaction (PPI) network analysis to identify the potential hub genes. In our study, we identified changes in the expression of genes involved in proliferation regulation, cell adhesion, immune response and transcriptional regulation in immortalized MEFs. In addition, we performed a comparative analysis with previously reported MEF immortalization data, where we propose a predicted gene regulatory network model in immortalized MEFs based on the altered expression of Mapk11, Cdh1, Chl1, Zic1, Hoxd10 and the novel hub genes Il6 and Itgb2.

Abstract
Background Hepatocellular carcinoma (HCC) is one of the most prevalent primary liver carcinoma. Guanine nucleotide-binding protein, α-activating activity polypeptide O (GNAO1) was reported to be under-expressed in HCC tissues. This study aimed to investigate the GNAO1-derived circular RNA (circRNA) and its molecular mechanisms in HCC. Methods Real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot were applied to examine RNA and protein levels. Functional experiments were performed to study HCC cell proliferation, cell cycle and cellular senescence. The interactions among circGNAO1, GNAO1 and DNA methyltransferase 1 (DNMT1) were examined by mechanism assays. The methylation level was analyzed by bisulfite sequencing PCR (BSP). Results CircGNAO1 is down-regulated and positively associated with GNAO1 in HCC tissues. Overexpression of circGNAO1 inhibits cell proliferation, induces cell cycle arrest and facilitates cell senescence in HCC cells. CircGNAO1 facilitates the progression of HCC via modulating GNAO1. Mechanistically, circGNAO1 enhances the transcription of GNAO1 by sequestering DNMT1, thereby up-regulating GNAO1 expression in HCC cells. Conclusions CircGNAO1 up-regulates its host gene GNAO1 expression for suppression of hepatocarcinogenesis.

Abstract
Cisplatin (CDDP), as a broad-spectrum anticancer drug, is able to bind to DNA and inhibit cell division. Despite the widespread use of cisplatin since its discovery, cisplatin resistance developed during prolonged chemotherapy, similar to other small molecule chemotherapeutic agents, severely limits its clinical application. Cisplatin resistance in cancer cells is mainly caused by three reasons: DNA repair, decreased cisplatin uptake/increased efflux, and cisplatin inactivation. In earlier combination therapies, the emergence of multidrug resistance (MDR) in cancer cells prevented the achievement of the desired therapeutic effect even with the accurate combination of two chemotherapeutic drugs. Therefore, combination therapy using nanocarriers for co-delivery of drugs is considered to be ideal for alleviating cisplatin resistance and reducing cisplatin-related toxicity in cancer cells. This article provides an overview of the design of cisplatin nano-drugs used to combat cancer cell resistance, elucidates the mechanisms of action of cisplatin and the pathways through which cancer cells develop resistance, and finally discusses the design of drugs and related carriers that can synergistically reduce cancer resistance when combined with cisplatin.

Abstract
Hepatocellular carcinoma (HCC), a significant challenge for public healthcare systems in developed Western countries including the USA, Canada, and the UK, is influenced by different risk factors including hepatitis virus infections, alcoholism, and smoking. The disruption in the balance of microRNAs (miRNAs) plays a vital function in tumorigenesis, given their function as regulators in numerous signaling networks. These miRNAs, which are mature and active in the cytoplasm, work by reducing the expression of target genes through their impact on mRNAs. MiRNAs are particularly significant in HCC as they regulate key aspects of the tumor, like proliferation and invasion. Additionally, during treatment phases such as chemotherapy and radiotherapy, the levels of miRNAs are key determinants. Pre-clinical experiments have demonstrated that altered miRNA expression contributes to HCC development, metastasis, drug resistance, and radio-resistance, highlighting related molecular pathways and processes like MMPs, EMT, apoptosis, and autophagy. Furthermore, the regulatory role of miRNAs in HCC extends beyond their immediate function, as they are also influenced by other epigenetic factors like lncRNAs and circular RNAs (circRNAs), as discussed in recent reviews. Applying these discoveries in predicting the prognosis of HCC could mark a significant advancement in the therapy of this disease.

Abstract
Hepatocellular carcinoma (HCC) is the most common type of liver cancer with a high death rate in the world. The molecular mechanisms related to the pathogenesis of HCC have not been precisely defined so far. Hence, this review aimed to address the potential cross-talk between noncoding RNAs (ncRNAs) and programmed cell death in HCC. All related papers in the English language up to June 2023 were collected and screened. The searched keywords in scientific databases, including Scopus, PubMed, and Google Scholar, were HCC, ncRNAs, Epigenetic, Programmed cell death, Autophagy, Apoptosis, Ferroptosis, Chemoresistance, Tumor recurrence, Prognosis, and Prediction. According to the reports, ncRNAs, comprising long ncRNAs, microRNAs, circular RNAs, and small nucleolar RNAs can affect cell proliferation, migration, invasion, and metastasis, as well as cell death-related processes, such as autophagy, ferroptosis, necroptosis, and apoptosis in HCC by regulating cancer-associated genes and signaling pathways, for example, phosphoinositide 3-kinase/Akt, extracellular signal-regulated kinase/MAPK, and Wnt/β-catenin signaling pathways. It seems that ncRNAs, as epigenetic regulators, can be utilized as biomarkers in diagnosis, prognosis, survival and recurrence rates prediction, chemoresistance, and evaluation of therapeutic response in HCC patients. However, more scientific evidence is suggested to be accomplished to confirm these results.

Abstract
Hepatocellular carcinoma (HCC), the most common form of primary liver cancers, accounts for a significant portion of cancer-related death globally. However, the molecular mechanisms driving the onset and progression of HCC are still not fully understood. Emerging evidence has indicated that non-protein-coding regions of genomes could give rise to transcripts, termed non-coding RNA (ncRNA), forming novel functional driving force for aberrant cellular activity. Over the past decades, overwhelming evidence has denoted involvement of a complex array of molecular function of ncRNAs at different stages of HCC tumorigenesis and progression. In this context, several pre-clinical studies have highlighted the potentials of ncRNAs as novel therapeutic modalities in the management of human HCC. Moreover, N6-methyladenosine (m6A) modification, the most prevalent form of internal mRNA modifications in mammalian cells, is essential for the governance of biological processes within cells. Dysregulation of m6A in ncRNAs has been implicated in human carcinogenesis, including HCC. In this review, we will discuss dysregulation of several hallmark ncRNAs (miRNAs, lncRNAs, and circRNAs) in HCC and address the latest advances for their involvement in the onset and progression of HCC. We also focus on dysregulation of m6A modification and various m6A regulators in the etiology of HCC. In the end, we discussed the contemporary preclinical and clinical application of ncRNA-based and m6A-targeted therapies in HCC.

Abstract
Liver cancer ranks as the third leading cause of cancer-related mortality worldwide, predominantly in the form of hepatocellular carcinoma (HCC). Conventional detection and treatment approaches have proven inadequate for addressing the elevated incidence and mortality rates associated with HCC. However, a significant body of research suggests that combating HCC through the induction of ferroptosis is possible. Ferroptosis is a regulated cell death process characterized by elevated levels of reactive oxygen species (ROS) and lipid peroxide accumulation, both of which are dependent on iron levels. In recent years, there has been an increasing focus on investigating ferroptosis, revealing its potential as an inhibitory mechanism against various diseases, including tumors. Therefore, ferroptosis induction holds great promise for treating multiple types of cancers, including HCC. This article provides a review of the key mechanisms involved in ferroptosis and explores the potential application of multiple targets and pathways associated with ferroptosis in HCC treatment to improve therapeutic outcomes.

[PMID: 38589413 PMCID: PMC11001896 DOI: 10.1038/s41598-024-58708-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 04/02/2024] [Indexed: 04/10/2024] Open
Abstract
The role of circular RNA (circRNAs) in hepatocellular carcinoma (HCC) has been extensively studied. Previous research has highlighted the regulatory role of circSNX6 in HCC cells and tissues. However, the precise mechanism underlying HCC progression still requires comprehensive investigation. The study initially utilized quantitative reverse transcription-polymerase chain reaction (qRT-PCR) to assess circSNX6 expression levels in HCC cell lines and tissues. Subsequently, the stability of circRNA was evaluated through Ribonuclease R and actinomycin D treatment assays. The impact of circSNX6 knockdown on proliferation, migration, invasion, and angiogenesis abilities was determined using various assays including colony formation, Transwell culture system, tube formation assay, and cell counting kit (CCK)-8 assays. Additionally, RNA immunoprecipitation chip and dual-luciferase reporter assays were employed to investigate the interactions between circSNX6 and miR-383-5p. Finally, an HCC xenograft tumor model in mice was established to assess the in vivo expression of circSNX6 and its functional role in HCC. Our findings revealed an elevated circSNX6 expression in HCC tissues, which was correlated with poor patient prognosis. Knockdown of circSNX6 suppressed HCC cell growth, invasion, metastasis, and angiogenesis. The downregulation of miR-383-5p, a target of circSNX6, significantly attenuated the tumor-suppressive effects induced by circSNX6 knockdown. Moreover, circSNX6 was found to modulate VEGFA expression by targeting miR-383-5p. The inhibition of HCC cell proliferation by miR-383-5p could be partially reversed by overexpressing VEGFA. Silencing circSNX6 also suppressed tumor formation and the metastasis of HCC cells in a mouse model. In summary, our findings suggest that circSNX6 promotes cell proliferation, metastasis, and angiogenesis in HCC by regulating the miR-383-5p/VEGFA pathway.

[PMID: 38428701 DOI: 10.1016/j.critrevonc.2024.104312] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 02/01/2024] [Accepted: 02/26/2024] [Indexed: 03/03/2024] Open
Abstract
The concept of 'Hallmarks of Cancer' is an approach of reducing the enormous complexity of cancer to a set of guiding principles. As the underlying mechanism of cancer are portrayed, we find that we gain insight and additional aspects of the disease arise. The understanding of the tumor microenvironment (TME) brought a new dimension and led to the discovery of novel hallmarks such as senescent cells, non-mutational epigenetic reprogramming, polymorphic microbiomes and unlocked phenotypic plasticity. Circular RNAs (circRNAs) are single-stranded, covalently closed RNA molecules that are ubiquitous across all species. Recent studies on the circRNAs have highlighted their crucial function in regulating the formation of human malignancies through a range of biological processes. The primary goal of this review is to clarify the role of circRNAs in the most common form of liver cancer, hepatocellular carcinoma (HCC). This review also addressed the topic of how circRNAs affect HCC hallmarks, including the new generation hallmarks. Finally, the enormous applications that these rapidly expanding ncRNA molecules serve in the functional and molecular development of effective HCC diagnostic biomarkers and therapeutic targets.

Animals (Basel) 2024; 14:576. [PMID: 38396545 PMCID: PMC10885906 DOI: 10.3390/ani14040576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Revised: 02/05/2024] [Accepted: 02/06/2024] [Indexed: 02/25/2024] Open
Abstract
CircRNA, a recently characterized non-coding RNA (ncRNA) variant, functions as a molecular sponge, exerting regulatory control by binding to microRNA (miRNA) and modulating the expression of downstream proteins, either promoting or inhibiting their expression. Among poultry species, geese hold significant importance, prized by consumers for their delectable taste and rich nutritional content. Despite the prominence of geese, research on the growth and development of goose muscle, particularly the regulatory role of circRNAs in goose muscle formation, remains insufficiently explored. In this study, we constructed comprehensive expression profiles of circRNAs and messenger RNAs (mRNAs) within the myoblasts and myotubes of Shitou geese. We identified a total of 96 differentially expressed circRNAs (DEcircRNAs) and 880 differentially expressed mRNAs (DEmRNAs). Notably, the parental genes of DEcircRNAs and DEmRNAs exhibited enrichment in the Wnt signaling pathway, highlighting its potential impact on the proliferation and differentiation of goose myoblasts. Employing RNAhybrid and miRDB, we identified circRNA-miRNA pairs and mRNA-miRNA pairs that may play a role in regulating myogenic differentiation or muscle growth. Subsequently, utilizing Cytoscape, we constructed a circRNA-miRNA-mRNA interaction network aimed at unraveling the intricate regulatory mechanisms involved in goose muscle growth and development, which comprises 93 circRNAs, 351 miRNAs, and 305 mRNAs. Moreover, the identification of 10 hub genes (ACTB, ACTN1, BDNF, PDGFRA, MYL1, EFNA5, MYSM1, THBS1, ITGA8, and ELN) potentially linked to myogenesis, along with the exploration of their circRNA-miRNA-hub gene regulatory axis, was also conducted. These competitive endogenous RNA (ceRNA) regulatory networks elucidate the molecular regulatory mechanisms associated with muscle growth in Shitou geese, providing deeper insights into the reciprocal regulation of circRNA, miRNA, and mRNA in the context of goose muscle formation.

Abstract
A growing number of studies have indicated that circRNAs play an important role in the progression of malignant tumors, including hepatocellular carcinoma (HCC). In this study, we designed to explore the abnormal expression of hsa_circ_0091579 (circ_0091579) and its role in the pathogenesis of HCC. In this study, the mRNA levels of circ_0091579, miR-1270, and Yes-associated protein (YAP1) were assessed by quantitative real-time polymerase chain reaction (qRT-PCR). RNase R and Actinomycin D were used to test the stability of circ_0091579. Cell Counting Kit-8 (CCK-8) was used to measure cell viability. Tubule formation assay was used to determine the effect of HCC cells on the number of tubes. Cell apoptosis was detected by flow cytometry. Western blot was used for the protein levels. Transwell and wound healing tests were used to measure the abilities of invasion and migration. The effect of circ_0091579 knockdown on tumor growth was verified in vivo by xenograft tumor assay and Immunohistochemistry (IHC) analysis. Dual-luciferase reporter or RIP assay was used to detect the relationship between miR-1270 and circ_0091579 or YAP1. Glutamine metabolism was determined by ELISA and western blot assays. In the present study, we found that circ_0091579 was upregulated in HCC tissues and cells. Inhibited circ_0091579 expression significantly suppressed proliferation and promoted apoptosis of HCC cells. Moreover, circ_0091579 knockdown inhibited tumor growth in vivo. Bioinformatic prediction and luciferase assay showed that circ_0091579 acted as a molecular sponge for miR-1270 and YAP1 was a target gene of miR-1270. MiR-1270 silencing could reverse the inhibitory effect of circ_0091579 knockdown on HCC progression, and YAP1 overexpression also could reverse the suppressive effect of circ_0091579 silencing on HCC progression. Meanwhile, miR-1270 inhibitor could invert the negative regulation effect of circ_0091579 silencing on YAP1 expression. Circ_0091579 promoted HCC progression by regulating the miR-1270/YAP1 axis, and our study might offer novel biomarkers and therapeutic targets for HCC.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common aggressive tumors in the world. Despite the availability of various treatments, its prognosis remains poor due to the lack of specific diagnostic indicators and the high heterogeneity of HCC cases. CircRNAs are noncoding RNAs with stable and highly specific expression. Extensive research evidence suggests that circRNAs mediate the pathogenesis and progression of HCC through acting as miRNA sponges, protein modulators, and translation templates. Tumor microenvironment (TME) has become a hotspot of immune-related research in recent years due to its effects on metabolism, secretion and immunity of HCC. Accordingly, understanding the role played by circRNAs in TME is important for the study of HCC. This review will discuss the crosstalk between circRNAs and TME in HCC. In addition, we will discuss the current deficiencies and controversies in research on circRNAs and predict future research directions.

Abstract
The losses caused by Vibrio infections in the aquaculture industry are challenging to quantify. In the face of antibiotic resistance, a natural and environmentally friendly alternative is urgently needed. In this study, we identify E3 ubiquitin-protein ligase RNF103 (rnf103) as a crucial target involved in immune evasion by Vibrio anguillarum. Our research demonstrates that Rnf103 promotes immune escape by inhibiting Traf6. Interestingly, we discover a circular RNA (circRNA), circRnf103, formed by reverse splicing of the Rnf103 gene. Predictive analysis and experimentation reveal that circRnf103 encodes Rnf103-177aa, a protein that competes with Rnf103 and binds to Traf6, preventing its degradation. Notably, circRnf103 therapy induces Rnf103-177aa protein production in zebrafish. In zebrafish models, circRnf103 exhibits significant effectiveness in treating V. anguillarum infections, reducing organ burden. These findings highlight the potential of circRNA therapy as a natural and innovative approach to combat infectious diseases sustainably, particularly in aquaculture and environmental management.

Abstract
Hepatocellular carcinoma (HCC) is a highly fatal malignancy with limited therapeutic options and high recurrence rates. Recently, immunotherapeutic agents such as immune checkpoint inhibitors (ICIs) have emerged as a new paradigm shift in oncology. ICIs, such as programmed cell death protein 1 (PD-1) inhibitors, have provided a new source of hope for patients with advanced HCC. Yet, the eligibility criteria of HCC patients for ICIs are still a missing piece in the puzzle. Circular RNAs (circRNAs) have recently emerged as a new class of non-coding RNAs that play a fundamental role in cancer pathogenesis. Structurally, circRNAs are resistant to exonucleolytic degradation and have a longer half-life than their linear counterparts. Functionally, circRNAs possess the capability to influence various facets of the tumor microenvironment, especially at the HCC tumor-immune synapse. Notably, circRNAs have been observed to control the expression of immune checkpoint molecules within tumor cells, potentially impeding the therapeutic effectiveness of ICIs. Therefore, this renders them potential cancer-immune biomarkers for diagnosis, prognosis, and therapeutic regimen determinants. In this review, the authors shed light on the structure and functional roles of circRNAs and, most importantly, highlight the promising roles of circRNAs in HCC immunomodulation and their potential as promising biomarkers and immunotherapeutic regimen determinants.

Aberrant expression of circular RNA DHPR facilitates tumor growth and metastasis by regulating the RASGEF1B/RAS/MAPK axis in hepatocellular carcinoma. Cell Oncol (Dordr) 2023; 46:1333-1350.

Abstract
BACKGROUND Circular RNAs (circRNAs) are noncoding RNAs. Accumulating evidence suggests that circRNAs play a critical role in human biological processes, especially tumorigenesis, and development. However, the exact mechanisms of action of circRNAs in hepatocellular carcinoma (HCC) remain unclear. METHODS Bioinformatic tools and RT-qPCR were used to identify the role of circDHPR, a circRNA derived from the dihydropteridine reductase (DHPR) locus, in HCC and para-carcinoma tissues. Kaplan-Meier analysis and the Cox proportional hazard model were used to analyze the correlation between circDHPR expression and patient prognosis. Lentiviral vectors were used to establish stable circDHPR-overexpressing cells. In vitro and in vivo studies have shown that tumor proliferation and metastasis are affected by circDHPR. Mechanistic assays, including Western blotting, immunohistochemistry, dual-luciferase reporter assays, fluorescence in situ hybridization, and RNA immunoprecipitation, have demonstrated the molecular mechanism underlying circDHPR. RESULTS CircDHPR was downregulated in HCC, and low circDHPR expression was associated with poor overall survival and disease-free survival rates. CircDHPR overexpression inhibits tumor growth and metastasis in vitro and in vivo. Further systematic studies revealed that circDHPR binds to miR-3194-5p, an upstream regulator of RASGEF1B. This endogenous competition suppresses the silencing effect of miR-3194-5p. We confirmed that circDHPR overexpression inhibited HCC growth and metastasis by sponging miR-3194-5p to upregulate the expression of RASGEF1B, which is regarded as a suppressor of the Ras/MAPK signaling pathway. CONCLUSIONS Aberrant circDHPR expression leads to uncontrolled cell proliferation, tumorigenesis, and metastasis. CircDHPR may serve as a biomarker and therapeutic target for HCC.

Abstract
Non-small cell lung cancer (NSCLC) is one of the most common malignant tumors worldwide. Circular RNAs (circRNAs) have been widely reported to play a role in the pathogenesis of various tumors. Nevertheless, the function of circ_0001955 in NSCLC progression has not been explored yet. This study aims to explore the functions of circ_0001955 in NSCLC and investigate its regulatory molecular mechanism. First, we determined that circ_0001955 was upregulated in NSCLC cells. Subsequently, we demonstrated that knockdown of circ_0001955 restrained cell proliferation and invasion. In vivo experiments further proved the suppressive effect of circ_0001955 silence on tumor growth. Mechanism assays revealed that circ_0001955 enhanced nuclear factor-κB (NF-κB) inhibitor interacting Ras-like protein 2 (NKIRAS2) expression by sponging microRNA-29a-3p (miR-29a-3p). Upregulation of NKIRAS2 led to the deceased level of IκBβ but increased levels of nuclear p65, thus activating the NF-κB signaling pathway. In conclusion, Circ_0001955 activates the NF-κB pathway to promote NSCLC cell proliferation and invasion by regulating miR-29a-3p/NKIRAS2 axis.

Abstract
Previous studies have demonstrated that mitogen-activated protein kinase 11 (MAPK11) functions as an important point of integration in signalling transduction pathways and controlling endocellular processes, including viability of cells, differentiation, proliferation and apoptosis, through the sequence phosphorylation of the substrate protein Ser/Thr kinase protein cascade. Though MAPK 11 plays an important role in various tumours, especially in the invasive and metastatic processes, its expression and molecular mechanism in clear cell renal cell carcinoma (ccRCC) remain unclear. Runt-associated transcription factor 2 (RUNX2), a main transcription factor for osteoblast differentiation and chondrocyte maturation, has high expression in a number of tumours. In this study, the mRNA and protein levels of targeted genes in ccRCC tissues and adjacent tissues are analysed using the Cancer Genome Atlas (TCGA) database and western blotting. The ccRCC cell proliferation was measured with colony formation and EdU assay, and cell migration was examined through transwell assay. The interactive behaviour between proteins was detected with immunoprecipitation. Half-life period of RUNX2 protein was measured with cycloheximide chase assay. The results of the study indicated overexpression of MAPK11 and RUNX2 in ccRCC tissues and cell lines. MAPK11 and RUNX2 promoted the ccRCC cell proliferation and migration. Additionally, physical interaction took place between RUNX2 and P-MAPK11, which functioned to sustain the stability of RUNX2 protein. The high expression of RUNX2 could neutralize the functional degradation in MAPK11. And the outcomes of the study suggest that the P-MAPK11/RUNX2 axis may be used as a potential therapeutic target of ccRCC.

Abstract
Atrial fibrosis is a crucial contributor to initiation and perpetuation of atrial fibrillation (AF). This study aimed to identify a circRNA-miRNA-mRNA competitive endogenous RNA (ceRNA) regulatory network related to atrial fibrosis in AF, especially to validate hsa_circ_0000672/hsa_miR-516a-5p/TRAF6 ceRNA axis in AF preliminarily. The circRNA-miRNA-mRNA ceRNA network associated with AF fibrosis was constructed using bioinformatic tools and literature reviews. Left atrium (LA) low voltage was used to represent LA fibrosis by using LA voltage matrix mapping. Ten controls with sinus rhythm (SR), and 20 patients with persistent AF including 12 patients with LA low voltage and 8 patients with LA normal voltage were enrolled in this study. The ceRNA regulatory network associated with atrial fibrosis was successfully constructed, which included up-regulated hsa_circ_0000672 and hsa_circ_0003916, down-regulated miR-516a-5p and five up-regulated hub genes (KRAS, SMAD2, TRAF6, MAPK11 and SMURF1). In addition, according to the results of Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, these hub genes were clustered in TGF-beta and MAPK signaling pathway. In the patients with persistent AF, hsa_circ_0000672 expression in peripheral blood monocytes was significantly higher than those in controls with SR by quantitative real-time polymerase chain reaction (p-value < 0.001). Furthermore, hsa_circ_0000672 expression was higher in peripheral blood monocytes of persistent AF patients with LA low voltage than those with LA normal voltage (p-value = 0.002). The dual-luciferase activity assay confirmed that hsa_circ_0000672 exerted biological functions as a sponge of miR-516a-5p to regulate expression of its target gene TRAF6. Hsa_circ_0000672 expression in peripheral blood monocytes may be associated with atrial fibrosis. The hsa_circ_0000672 may be involved in atrial fibrosis by indirectly regulating TRAF6 as a ceRNA by sponging miR-516a-5p.

Abstract
Over the last four decades, methodological innovations have continuously changed transcriptome profiling. It is now feasible to sequence and quantify the transcriptional outputs of individual cells or thousands of samples using RNA sequencing (RNA-seq). These transcriptomes serve as a connection between cellular behaviors and their underlying molecular mechanisms, such as mutations. This relationship, in the context of cancer, provides a chance to unravel tumor complexity and heterogeneity and uncover novel biomarkers or treatment options. Since colon cancer is one of the most frequent malignancies, its prognosis and diagnosis seem to be critical. The transcriptome technology is developing for an earlier and more accurate diagnosis of cancer which can provide better protectivity and prognostic utility to medical teams and patients. A transcriptome is a whole set of expressed coding and non-coding RNAs in an individual or cell population. The cancer transcriptome includes RNA-based changes. The combined genome and transcriptome of a patient may provide a comprehensive picture of their cancer, and this information is beginning to affect treatment decision-making in real-time. A full assessment of the transcriptome of colon (colorectal) cancer has been assessed in this review paper based on risk factors such as age, obesity, gender, alcohol use, race, and also different stages of cancer, as well as non-coding RNAs like circRNAs, miRNAs, lncRNAs, and siRNAs. Similarly, they have been examined independently in the transcriptome study of colon cancer.

Abstract
BACKGROUND Circular RNAs (circRNAs) possess key functions in the pathogenesis of hepatocellular carcinoma (HCC). Nonetheless, the actions of individual circRNAs in HCC remain undefined. METHODS circ_0031242, miR-944, and MAD2L1 expression were quantified by qRT-PCR. Transwell assay was utilized to examine cell invasion and migration. Glucose consumption and lactate production were measured to assess the impact on glycolysis. The relationships among circ_0031242, MAD2L1, and miR-944 were examined via luciferase reporter assay. RESULTS circ_0031242 was notably augmented in HCC. Loss of function of circ_0031242 hindered cell proliferation, invasion, migration, glycolysis, and promoted apoptosis, as well as impeding HCC tumor growth. circ_0031242 directly targeted miR-944. Inhibition of miR-944 counteracted the effects of si-circ_0031242 on HCC cells. Additionally, miR-944 was proved to directly target MAD2L1 in HCC cells. Moreover, the promotion of MAD2L1 was able to rescue the inhibition of high miR-944 expression on HCC cell progression. Meanwhile, circ_0031242 involved the post-transcriptional modulation of MAD2L1 through miR-944. CONCLUSION This study suggested that circ_0031242 regulated tumor cell progression and tumor growth through the miR-944/MAD2L1 axis in HCC.

Abstract
Circular RNAs (circRNAs) are a class of endogenous RNAs that control gene expression at the transcriptional and post-transcriptional levels. Recent studies have increasingly demonstrated that circRNAs act as novel diagnostic biomarkers and promising therapeutic targets for numerous cancer types by interacting with other non-coding RNAs such as microRNAs (miRNAs). The miRNAs are presented as crucial risk factors and regulatory elements in cancer by regulating the expression of their target genes. Some miRNAs are derived from transposable elements (MDTEs) that can transfer their location to another region of the genome. Genetic interactions between miRNAs and circular RNAs can form complex regulatory networks with various carcinogenic processes that play critical roles in tumorigenesis and cancer progression. This review focuses on the biological regulation of the correlative axis among circular RNAs, miRNAs, and their target genes in various cancer types and suggests the biological importance of MDTEs interacting with oncogenic or tumor-suppressive circRNAs in tumor progression.

Abstract
Bladder cancer (BC) is among the most common malignant tumors of the genitourinary system worldwide. In recent years, the rate of BC incidence has increased, and the recurrence rate is high, resulting in poor quality of life for patients. Therefore, how to develop an effective method to achieve synchronous precise diagnoses and BC therapies is a difficult problem to solve clinically. Previous reports usually focus on the role of nanomaterials as drug delivery carriers, while a summary of the functional design and application of nanomaterials is lacking. Summarizing the application of functional nanomaterials in high-sensitivity diagnosis and multimodality therapy of BC is urgently needed. This review summarizes the application of nanotechnology in BC diagnosis, including the application of nanotechnology in the sensoring of BC biomarkers and their role in monitoring BC. In addition, conventional and combination therapies strategy in potential BC therapy are analyzed. Moreover, different kinds of nanomaterials in BC multimodal therapy according to pathological features of BC are also outlined. The goal of this review is to present an overview of the application of nanomaterials in the theranostics of BC to provide guidance for the application of functional nanomaterials to precisely diagnose and treat BC.

Abstract
Background Cisplatin (DDP) is among the most widely used chemotherapeutic drugs for non-small cell lung cancer (NSCLC), yet the frequent emergence of chemoresistance serves as a major barrier to the treatment of this tumor type. Long non-coding RNAs (lncRNAs) have recently been shown to influence the ability of cells to resist particular chemotherapy drugs. The present study was developed to explore the role of the lncRNA SNHG7 as a regulator of NSCLC cell chemosensitivity. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to measure SNHG7 expression in NSCLC tissues from patients that were sensitive/resistant to DDP, correlations between SNHG7 expression levels and the patients' clinicopathological characteristics were assessed, and the prognostic relevance of SNHG7 expression was examined via the Kaplan-Meier approach. In addition, SNHG7 expression was assessed in NSCLC cell lines that were DDP-sensitive or -resistant, while western blotting and immunofluorescence staining were employed to detect autophagy-associated protein expression in A549, A549/DDP, HCC827, and HCC827/DDP cells. NSCLC cell chemoresistance was quantified via the Cell Counting Kit-8 (CCK-8) assay approach, and flow cytometry was used to detect the apoptotic death of these tumor cells. The chemosensitivity of xenograft tumors in vivo was further assessed to validate the functional importance of SNHG7 as a regulator of NSCLC DDP resistance. Results Relative to paracancerous tissues, NSCLC tumors exhibited SNHG7 upregulation, and this lncRNA was further upregulated in DDP-resistant patients compared to chemosensitive patients. Consistently, higher SNHG7 expression levels were correlated with worse patient survival outcomes. DDP-resistant NSCLC cells were also found to exhibit higher levels of SNHG7 expression than chemosensitive cells, and knocking down this lncRNA enhanced the sensitivity of these cells to DDP treatment, resulting in impaired proliferation and higher rates of apoptotic death. Knocking down SNHG7 was also sufficient to suppress microtubule associated protein 1 light chain 3 beta (LC3B) and Beclin1 protein levels and promote p62 upregulation in vitro. The silencing of this lncRNA additionally inhibited the resistance of NSCLC xenograft tumors to DDP treatment in vivo. Conclusions SNHG7 can promote malignant behaviors and DDP resistance in NSCLC cells at least partly via the induction of autophagic activity.

Abstract
BACKGROUND Circular RNA (circRNA) has been found to play an important role in the progression of many diseases, including ischemic stroke. However, the regulatory mechanism of circSEC11A in ischemic stroke progression need to further investigation. METHODS Human brain microvascular endothelial cells (HBMECs) were stimulated by oxygen glucose deprivation (OGD). CircSEC11A, SEC11A mRNA and miR (microRNA)-29a-3p were quantified by quantitative real-time PCR (qRT-PCR). SEMA3A, BAX and BCL2 protein level was quantified by western blot. Oxidative stress, cell proliferation, angiogenesis and apoptosis abilities were gauged by oxidative stress assay kit, 5-Ethynyl-2'-Deoxyuridine (EdU) staining, tube formation assay and flow cytometry assays, respectively. Direct relationship between miR-29a-3p and circSEC11A or SEMA3A was validated by dual-luciferase reporter assay, RIP assay and RNA pull-down assay. RESULTS CircSEC11A was upregulated in OGD-induced HBMECs. OGD promoted the oxidative stress and apoptosis and inhibited cell proliferation and angiogenesis, while circSEC11A knockdown relieved the effects. CircSEC11A functioned as the sponge for miR-29a-3p, and miR-29a-3p inhibitor reversed the effects of si-circSEC11A on OGD-induced HBMECs oxidative injuries. Moreover, SEMA3A served as the target gene of miR-29a-3p. MiR-29a-3p inhibition ameliorated OGD-induced HBMECs oxidative injuries, while SEMA3A overexpression rescued the impacts of miR-29a-3p mimic. CONCLUSION CircSEC11A promoted the malignant progression in OGD-induced HBMECs through the mediation of miR-29a-3p/SEMA3A axis. This study has provided the new insight into the underlying application of circSEC11A in cell model of ischemic stroke.

Yao D, Nong L, Qin M, Wu S, Yao S. Identifying circRNA-miRNA interaction based on multi-biological interaction fusion. Front Microbiol 2022; 13:987930. [PMID: 36620017 PMCID: PMC9815023 DOI: 10.3389/fmicb.2022.987930] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 11/30/2022] [Indexed: 12/24/2022] Open
Abstract
CircRNA is a new type of non-coding RNA with a closed loop structure. More and more biological experiments show that circRNA plays important roles in many diseases by regulating the target genes of miRNA. Therefore, correct identification of the potential interaction between circRNA and miRNA not only helps to understand the mechanism of the disease, but also contributes to the diagnosis, treatment, and prognosis of the disease. In this study, we propose a model (IIMCCMA) by using network embedding and matrix completion to predict the potential interaction of circRNA-miRNA. Firstly, the corresponding adjacency matrix is constructed based on the experimentally verified circRNA-miRNA interaction, circRNA-cancer interaction, and miRNA-cancer interaction. Then, the Gaussian kernel function and the cosine function are used to calculate the circRNA Gaussian interaction profile kernel similarity, circRNA functional similarity, miRNA Gaussian interaction profile kernel similarity, and miRNA functional similarity. In order to reduce the influence of noise and redundant information in known interactions, this model uses network embedding to extract the potential feature vectors of circRNA and miRNA, respectively. Finally, an improved inductive matrix completion algorithm based on the feature vectors of circRNA and miRNA is used to identify potential interactions between circRNAs and miRNAs. The 10-fold cross-validation experiment is utilized to prove the predictive ability of the IIMCCMA. The experimental results show that the AUC value and AUPR value of the IIMCCMA model are higher than other state-of-the-art algorithms. In addition, case studies show that the IIMCCMA model can correctly identify the potential interactions between circRNAs and miRNAs.

Abstract
BACKGROUND Though circular RNAs (circRNAs) are the key regulators in tumor carcinogenesis, they remain largely unexplored in hepatocellular carcinoma (HCC). METHODS The expression of RanGAP1-derived circRNAs (circ_0063531, circ_0063534, circ_0063513, circ_0063518, circ_0063507, circ_0063723) were evaluated in eight paired HCC and normal tissues, and the correlation between circRanGAP1 (circ_0063531) expression and clinicopathological characteristics in 40 HCC patients was determined. The association between miR-27b-3p and circRanGAP1 or NRAS was predicted using bioinformatics analysis. The expression of circRanGAP1, miR-27b-3p, and NRAS were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The potential oncogenic role of circ-RanGAP1 was assessed using CCK-8, colony formation, transwell assays in vitro, subcutaneous tumor mouse model, vein tail metastatic model, and orthotopically implanted intrahepatic HCC model in vivo. Luciferase reporter and RNA immunoprecipitation (RIP) assays were used to explore the binding site between miR-27b-3p and circ-RanGAP1 or NRAS. Protein expression was detected using western blotting. The localization of miR-27b-3p and circ-RanGAP1 was investigated using fluorescence in situ hybridization (FISH). The level of immune infiltration was assessed by bioinformatics analysis, flow cytometry, and orthotopically implanted intrahepatic HCC models. RESULTS Here, we found elevated circRanGAP1 in the cells and clinical tissues of patients with HCC. Increased circRanGAP1 levels are associated with enlarged tumors and the advanced stage of TNM. CircRanGAP1 promotes the growth, migration, and HCC cell invasion, concurrently with the growth and metastasis of tumors in-vivo. Moreover, circRanGAP1 is mainly located inside the cytoplasm. Mechanistically, circRanGAP1 as an oncogene promotes HCC progression by miR-27b-3p/NRAS/ERK axis, furthermore, affects the infiltration level of tumor-associated macrophages probably by sponging miR-27b-3p. Immune infiltration analysis shows that NRAS is positively correlated with the levels of CD68+ tumor-associated macrophages in HCC samples and that NRAS and CD68 are related to the poor outcome of HCC. CONCLUSION These results reveal that circRanGAP1 is a HCC oncogene that function by the miR-27b-3p/NRAS/ERK axis and regulates the infiltration levels of tumor-associated macrophages by sponging miR-27b-3p. Therefore, circRANGAP1/ NRAS axis may be an important potential treatment target against HCC.

Abstract
Background Emerging evidence have revealed that circRNAs exert important biological effects in the development and progression of various diseases, including cancer. Our study aimed to elaborated the biological effects of hsa-circ_0003570 in hepatocellular carcinoma (HCC) development at the molecular level. Results The results of functional experiments showed that knockdown of circ_0003570 induced HCC cell growth, migration and invasion, whereas overexpression of circ_0003570 presented the opposite effects. In vivo experiments, xenograft tumors grown from circ-overexpressed cells had smaller tumor volume and weight than the control group. Further investigations suggested that circ_0003570 may function as a competing endogenous RNA via competitively binding miR-182-5p and thereby regulating the repression of downstream target gene STARD13, which were demonstrated by dual luciferase reporter assay and functional rescued experiments. Conclusions Taken together, circ_0003570 suppresses the development of HCC by modulating miR-182-5p/STARD13 axis.

Abstract
INTRODUCTION Colorectal cancer (CRC) has become one of the most common cancers in recent years. Given the importance that non-coding RNAs have recently acquired in various diseases including cancers, we decided to design this study to evaluate the expression levels of circ0001955/miR-145-5p/ONECUT2 axis in CRC. METHODS After bioinformatics analysis of GEO datasets related to CRC, a putative circ0001955/ miR-145-5p/ ONECUT2 pathway was assumed. Then, the expression levels of these genes were measured in 50 CRC samples and adjacent tissues by qRT- PCR. Also, correlation coefficients, receiver operating characteristic (ROC) curves, and correlation between circ0001955 levels with clinicopathological parameters of patients were analyzed. RESULTS Circ0001955 and ONECUT2 were considerably up-regulated, while the expression level of miR-145-5p was decreased in CRC samples compared with adjacent tissues (p < 0.05). Moreover, statistically significant correlations were observed between expression levels of circ0001955, miR-145-5p, and ONECUT2. We did not find any significant correlation between circ0001955 expression and clinicopathological parameters. CONCLUSION Our study showed that circ0001955 is dysregulated in CRC. This finding can open a new window for researchers for a better understanding of the potential pathways involved in CRC pathogenesis and, consequently, to find new treatment pathways.

Abstract
BACKGROUND Circular RNAs (circRNAs) play a vital role in cancer progression. However, there are still numerous circRNAs that have not been functionally explored. Our study aimed to disclose the role of circ-CSNK1G1 in triple-negative breast cancer (TNBC). METHODS The expression of circ-CSNK1G1, miR-28-5p and lactate dehydrogenase A (LDHA) mRNA was measured by quantitative real-time polymerase chain reaction (qPCR), and the expression of LDHA protein was measured by western blot. Cell proliferation was assessed using MTT assay and colony formation assay. Cell apoptosis was monitored using flow cytometry assay. Cell migration and cell invasion were investigated using transwell assay. Glycolysis progression was assessed according to glucose consumption, lactate production and ATP/ADP ratio. Tumor formation assay in nude mice was conducted to verify the role of circ-CSNK1G1 in vivo. The interplays between miR-28-5p and circ-CSNK1G1 or LDHA were confirmed by dual-luciferase reporter assay. RESULTS Circ-CSNK1G1 was upregulated in TNBC tissues and cells. Circ-CSNK1G1 knockdown suppressed cancer cell proliferation, migration, invasion and glycolysis energy metabolism, promoted cell apoptosis in vitro, and blocked tumor growth in vivo. Mechanism analysis showed that circ-CSNK1G1 positively regulated LDHA expression by suppressing miR-28-5p. Rescue experiments presented that circ-CSNK1G1 played functions by targeting miR-28-5p, and miR-28-5p participated in TNBC progression by degrading LDHA. CONCLUSION Circ-CSNK1G1 promotes cell proliferation, migration, invasion and glycolysis metabolism during TNBC development by regulating the miR-28-5p/LDHA pathway.

Abstract
Ferroptosis is a novel process of regulated cell death discovered in recent years, mainly caused by intracellular lipid peroxidation. It is morphologically manifested as shrinking of mitochondria, swelling of cytoplasm and organelles, rupture of plasma membrane, and formation of double-membrane vesicles. Work done in the past 5 years indicates that induction of ferroptosis is a promising strategy in the treatment of hepatocellular carcinoma (HCC). System xc-/GSH/GPX4, iron metabolism, p53 and lipid peroxidation pathways are the main focus areas in ferroptosis research. In this paper, we analyze the ferroptosis-inducing drugs and experimental agents that have been used in the last 5 years in the treatment of HCC. We summarize four different key molecular mechanisms that induce ferroptosis, i.e., system xc-/GSH/GPX4, iron metabolism, p53 and lipid peroxidation. Finally, we outline the prognostic analysis associated with ferroptosis in HCC. The findings summarized suggest that ferroptosis induction can serve as a promising new therapeutic approach for HCC and can provide a basis for clinical diagnosis and prevention of this disease.

Abstract
To elaborate on the role of circular RNA 0001955 (circ_0001955) on the proliferation and apoptosis of non-small cell lung cancer (NSCLC) cells and its underlying mechanism. Circ_0001955 expression in NSCLC was screened out through bioinformatics analysis based on GEO database. Circ_0001955, microRNA-769-5p (miR-769-5p), and epidermal growth factor receptor (EGFR) expression in NSCLC tissues and cell lines was examined using quantitative real-time PCR (qRT-PCR) and Western blot. Cell proliferation and apoptosis were examined using the CCK-8 method, BrdU experiment and flow cytometry analysis, respectively. Bioinformatics prediction, dual-luciferase reporter gene experiment and RNA immunoprecipitation (RIP) experiments were applied to validate the targeting relationship between miR-769-5p and circ_0001955 and the 3' UTR of EGFR. Pearson's correlation analysis was employed to validate the correlations among them. Circ_0001955 expression was up-regulated in NSCLC tissues and cell lines, and its overexpression was strongly associated with increased tumor TNM stage and lymph node metastasis. Circ_0001955 overexpression enhanced the proliferation and restrained the apoptosis in NSCLC cells, whereas knocking down circ_0001955 exerted the opposite effects. Circ_0001955 directly targeted miR-769-5p and negatively regulated its expression. EGFR, a target gene of miR-769-5p, could be indirectly and positively regulated by circ_0001955. Correlation analysis indicated that circ_0001955 was negatively correlated with miR-769-5p expression, while circ_0001955 was positively correlated with EGFR expression. Circ_0001955 facilitates the proliferation and represses the apoptosis of NSCLC cells by modulating miR-769-5p/EGFR axis.

[PMID: 35858900 PMCID: PMC9297645 DOI: 10.1186/s12943-022-01619-4] [Citation(s) in RCA: 75] [Impact Index Per Article: 37.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 07/05/2022] [Indexed: 11/30/2022] Open
Abstract
Background Emerging evidence indicates that circular RNAs (circRNAs) and m6A RNA methylation participate in the pathogenesis and metastasis of multiple malignancies including hepatocellular carcinoma (HCC). However, it remains undocumented how circRNAs form a feedback loop with the m6A modification contributing to HCC. Methods A novel hsa_circ_0017114 (circGPR137B) was identified from three pairs of primary HCC and adjacent normal tissues by circRNA expression profiling. The association of circGPR137B and miR-4739 with clinicopathological parameters and prognosis in patients with HCC was analyzed by RT-qPCR, fluorescence in situ hybridization and TCGA cohorts. The role of circGPR137B in HCC was estimated in vitro and in vivo. RT-qPCR, western blot, m6A dot blot, RIP, MeRIP and dual-luciferase reporter assays were used to validate the reciprocal regulation of the feedback loop among circGPR137B, miR-4739 and m6A demethylase FTO. Meanwhile, the expression, function and prognosis of FTO in HCC were investigated by RT-qPCR, western blot, TCGA and rescue experiments. Results We identified a new dramatically downregulated circGPR137B in HCC tissues, and found that downregulation of circGPR137B or upregulation of miR-4739 was associated with poor prognosis in patients with HCC. Ectopic expression of circGPR137B strikingly repressed the proliferation, colony formation and invasion, whereas knockdown of circGPR137B harbored the opposite effects. Moreover, restored expression of circGPR137B inhibited tumor growth and lung metastasis in vivo. Further investigations showed that circGPR137B, co-localized with miR-4739 in the cytoplasm, acted as a sponge for miR-4739 to upregulate its target FTO, which mediated m6A demethylation of circGPR137B and promoted its expression. Thus, a feedback loop comprising circGPR137B/miR-4739/FTO axis was formed. FTO suppressed cell growth and indicated favorable survival in patients with HCC. Conclusion Our results demonstrate that circGPR137B inhibits HCC tumorigenesis and metastasis through the circGPR137B/miR-4739/FTO feedback loop. This positive feedback mechanism executed by functional coupling between a circRNA sponge and an m6A modification event suggests a model for epigenetics.

Abstract
The laboratory mouse ranks among the most important experimental systems for biomedical research and molecular reference maps of such models are essential informational tools. Here, we present a quantitative draft of the mouse proteome and phosphoproteome constructed from 41 healthy tissues and several lines of analyses exemplify which insights can be gleaned from the data. For instance, tissue- and cell-type resolved profiles provide protein evidence for the expression of 17,000 genes, thousands of isoforms and 50,000 phosphorylation sites in vivo. Proteogenomic comparison of mouse, human and Arabidopsis reveal common and distinct mechanisms of gene expression regulation and, despite many similarities, numerous differentially abundant orthologs that likely serve species-specific functions. We leverage the mouse proteome by integrating phenotypic drug (n > 400) and radiation response data with the proteomes of 66 pancreatic ductal adenocarcinoma (PDAC) cell lines to reveal molecular markers for sensitivity and resistance. This unique atlas complements other molecular resources for the mouse and can be explored online via ProteomicsDB and PACiFIC.

[PMID: 34021822 DOI: 10.1007/s10620-021-07053-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Accepted: 05/11/2021] [Indexed: 01/10/2023]
Abstract
BACKGROUND Circular RNA (circRNA) exerts a crucial role in the progression of many cancers, including hepatocellular carcinoma (HCC). However, the function of circ_0001955 in HCC progression has been poorly studied. AIMS Elucidating the role and molecular mechanism of circ_0001955 in HCC progression. METHODS Quantitative real-time PCR was employed to detect the expression of circ_0001955 and miR-646. Cell counting kit 8 assay, Ethynyl-2-deoxyuridine assay, flow cytometry, transwell assay, and tube formation assay were conducted to measure cell proliferation, metastasis, angiogenesis and apoptosis. Dual-luciferase reporter assay and biotin-labeled RNA pull-down assay were performed to analyze the interactions among circ_0001955, miR-646 and frizzled class receptor 4 (FZD4). Moreover, animal experiments were performed to examine the influence of circ_0001955 on HCC tumor growth in vivo. RESULTS Circ_0001955 was a highly expressed circRNA in HCC tissues and cells. Circ_0001955 knockdown inhibited the proliferation, metastasis, angiogenesis, and enhanced the apoptosis of HCC cells. Meanwhile, miR-646 could be sponged by circ_0001955, and its inhibitor could reverse the negative regulation of circ_0001955 knockdown on HCC progression. Further, FZD4 was a target of miR-646, and its overexpression could invert the inhibition effect of miR-646 mimic on HCC progression. Besides, our results also indicated that circ_0001955 promoted FZD4 expression by sponging miR-646. Animal experiment results showed that circ_0001955 silencing restrained HCC tumor growth in vivo. CONCLUSION Our findings suggested that circ_0001955 might play a positive role in HCC progression via regulating the miR-646/FZD4 axis, indicating that circ_0001955 might be a potential therapeutic target for HCC.

[DOI: 10.11569/wcjd.v30.i9.393] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Circ_0044516 is highly expressed in gastric cancer, and inhibition of circ_0044516 can promote gastric cancer cell proliferation and induce apoptosis. Bioinformatics analysis predicts that miR-516a-5p binds to circ_0044516. The expression of miR-516a-5p is low in non-small cell lung cancer, but its role is unclear in gastric cancer cells. This study mainly explored the effect of circ_0044516 targeting miR-516a-5p on the proliferation, migration, and apoptosis of gastric cancer cells.
AIM To explore whether circ_0044516 targets and regulates miR-516a-5p and its effects on the proliferation, migration, and apoptosis of gastric cancer cells.
METHODS Quantitative real time polymerase chain reaction (qRT-PCR) was first used to detect the expression levels of circ_0044516 and miR-516a-5p in gastric epithelial cells GES-1 and gastric cancer cells (SNU-16 and HGC-27). HGC-27 cells were then divided into si-NC group (transfected with si-NC), si-circ_0044516 group (transfected with si-circ_0044516), miR-NC group (transfected with miR-NC), miR-516a-5p group (transfected with miR-516a-5p), si-circ_0044516 + anti-miR-NC group (co-transfected with si-circ_0044516 and anti-miR-NC), and si-circ_0044516 + anti-miR-516a-5p group (co-transfected with si-circ_0044516 and anti-miR-516a-5p). qRT-PCR was used to detect the expression levels of circ_0044516 and miR-516a-5p, MTT assay was used to detect cell proliferation, flow cytometry was performed to detect cell apoptosis, Transwell assay was used to detect cell migration, Western blot analysis was performed to detect the protein expression of p21, Bcl-2 associated X protein (Bax), B cell lymphoma/lewkmia-2 (Bcl-2), and matrix metalloproteinase 2 (MMP2), and dual luciferase reporter assay was ued to detect the targeting relationship between circ_0044516 and miR-516a-5p.
RESULTS Compared with gastric epithelial cells GES-1, the expression level of circ_0044516 was increased in gastric cancer cells SNU-16 and HGC-27, and the expression level of miR-516a-5p was decreased. Silencing circ_0044516 or overexpression of miR-516a-5p decreased the survival rate of gastric cancer cells and the number of migrating cells, increased the rate of cell apoptosis and the expression of p21 and Bax proteins, and reduced the expression of Bcl-2 and MMP2 proteins. Circ_0044516 targets and negatively regulates the expression of miR-516a-5p, and inhibition of miR-516a-5p partially restored the effect of silencing circ_0044516 on the proliferation, migration, and apoptosis of gastric cancer cells.
CONCLUSION Circ_0044516 inhibits cell proliferation and migration and induces apoptosis in gastric cancer cells through targeted negative regulation of miR-516a-5p.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a common cancer disease with the second highest mortality. Circular RNAs (circRNAs) have been shown to play key roles in many tumors, including HCC. However, the function of circ_0000854 in the progression of HCC has not been clarified. METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression levels of circ_0000854, microRNA-1294 (miR-1294) and immunity related GTPase Q (IRGQ) in HCC cells and tissues. Western blot was used for protein expression analysis. Cell processes were detected by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium Bromide (MTT) assay, thymidine analog 5-ethynyl-2'-deoxyuridine (EdU) assay, transwell assay, flow cytometry, and wound healing assay. Mechanically, the interaction of miR-1294 with circ_0000854 or IRGQ was notarized by dual-luciferase reporter assay and RNA pull-down assay. The xenotransplantation model was established to study the role of circ_0000854 in vivo. RESULTS Circ_0000854 and IRGQ were highly expressed in HCC tissues and cells, while miR-1294 was downregulated. Silencing circ_0000854 suppressed HCC cell malignant behaviors, including proliferation, cell cycle progression, migration and invasion. Circ_0000854 exhibited sponge effect on miR-1294 and miR-1294 inhibition reversed function of circ_0000854 knockdown. In addition, miR-1294 targeted IRGQ and circ_0000854 sponged miR-1294 to upregulate IRGQ. Overexpression of IRGQ restored miR-1294-induced anti-tumor regulation in HCC cells. Animal experiments confirmed that silencing circ_0000854 inhibited tumor growth and metastasis of HCC via mediating miR-1294 and IRGQ levels in vivo. CONCLUSION Circ_0000854 accelerated HCC progression via the miR-1294/IRGQ axis, providing a novel regulatory mechanism for HCC pathogenesis.

Abstract
Accumulating evidence indicates that circular RNAs (circRNAs) function as conclusive modulators in diverse tumors, including in hepatocellular carcinoma (HCC). Nonetheless, knowledge of the latent mechanisms involving circRNAs in HCC development is insufficient. circSEC24A (hsa_circ_0003528) was discovered by microarray analysis of patients with HCC. Binding sites between circSEC24A, miR-421, miR-421 and matrix metalloproteinase 3 (MMP3) were predicted using online bioinformatics tools. Interactions involving miRNA and target genes or circRNAs were verified by luciferase reporter-gene and RNA pull-down assays. Two HCC cell lines (HCCLM3 and Hep3B) and normal THLE-2 liver cells were used for in vitro experiments. miRNA and mRNA expression levels were detected by RT-qPCR, and protein expression was measured by western blotting. Cell proliferation was evaluated using Cell Counting Kit 8 (CCK-8) assays along with colony formation assays. Cell invasion and migration were determined using the Transwell and wound healing migration assays. A xenograft model was used to evaluate the role of circSEC24A in vivo. circSEC24A expression was significantly upregulated in HCCLM3 and Hep3B cells. Silencing circSEC24A mitigated the proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) of HCC cells, which was abrogated by downregulation of miR-421. Meanwhile, MMP3 could bind to miR-421 to decrease the functional effects of miR-421 and induce tumor metastasis. Knockdown of cicSEC24A suppressed tumor growth in vivo. circSEC24A interference suppressed HCC cell EMT by sponging miR-421, further regulating MMP3, and inhibiting tumor growth in vivo. Therefore, circSEC24A could represent a potential target for HCC patient treatment.

Abstract
Background Hepatocellular carcinoma (HCC), as the most common type of liver cancer, is characterized by high recurrence and metastasis. Circular RNA (circRNA) circ_0036412 was selected for studying the underlying mechanisms of HCC. Methods Quantitative real time-polymerase chain reaction (qRT-PCR) and western blot analyzed gene and protein expression. Functional experiments evaluated HCC cell proliferation, apoptosis and cell cycle in vitro. In vivo experiments detected HCC carcinogenesis in vivo. Fluorescence in situ hybridization (FISH) assays evaluated the subcellular distribution. Luciferase reporter, Chromatin immunoprecipitation (ChIP), DNA pulldown, RNA-binding protein immunoprecipitation (RIP), and RNA pulldown assays detected the underlying mechanisms. Results Circ_0036412 is overexpressed in HCC cells and features circular structure. PRDM1 activates circ_0036412 transcription to regulate the proliferation and cell cycle of HCC cells in vitro. Circ_0036412 modulates Hedgehog pathway. GLI2 propels HCC growth in vivo. Circ_0036412 up-regulates GLI2 expression by competitively binding to miR-579-3p, thus promoting the proliferation and inhibiting cell cycle arrest of HCC cells. Circ_0036412 stabilizes GLI2 expression by recruiting ELAVL1. Circ_0036412 propels the proliferation and inhibits cell cycle arrest of HCC cells in vitro through Hedgehog pathway. Conclusions Circ_0036412 affects the proliferation and cell cycle of HCC via Hedgehog signaling pathway. It offers an insight into the targeted therapies of HCC. Graphical Abstract ![]()

Extracellular Vesicle-Mediated IL-1 Signaling in Response to Doxorubicin Activates PD-L1 Expression in Osteosarcoma Models. Cells 2022; 11:cells11061042. [PMID: 35326493 PMCID: PMC8946890 DOI: 10.3390/cells11061042] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 03/12/2022] [Accepted: 03/16/2022] [Indexed: 02/04/2023] Open
Abstract
The expression of programmed cell death ligand 1 (PD-L1) in tumors is associated with tumor cell escape from T-cell cytotoxicity, and is considered a crucial effector in chemoresistance and tumor relapse. Although PD-L1 induction has been observed in patients after chemotherapy treatment, the mechanism by which the drug activates PD-L1 expression remains elusive. Here, we identified the extracellular vesicles (EVs) as a molecular mediator that determines the effect of doxorubicin on PD-L1 expression in osteosarcoma models. Mechanistically, doxorubicin dependently stimulates the release of extracellular vesicles, which mediate autocrine/paracrine signals in osteosarcoma cells. The recipient cells were stimulated by these EVs and acquired the ability to promote the expression of inflammatory cytokines interleukin (IL)-1β and IL-6. In response to doxorubicin, IL-1β, but not IL-6, allowed- osteosarcoma cells to promote the expression of PD-L1, and the elimination of IL-1β/IL-1 receptor signaling with IL-1 receptor antagonist reduced PD-L1 expression. Together, these findings provided insights into the role of EV release in response to chemotherapy that mediates PD-L1 expression via the IL-1 signaling pathway, and suggested that the combination of a drug targeting IL-1 or PD-L1 with chemotherapy could be an effective treatment option for osteosarcoma patients.

Abstract
Background Reportedly, circular RNA (circRNA) is a key modulator in the development of human malignancies. This work is aimed to probe the expression pattern, biological effects and mechanism of circ_0064288 on hepatocellular carcinoma (HCC) progression. Methods The differentially expressed circRNA was screened by analyzing the expression profiles of circRNAs in HCC tissues and normal tissues. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to examine the expression of circ_0064288, miR-335-5p and Rho associated coiled-coil containing protein kinase 1 (ROCK1) mRNA in HCC specimens. After circ_0064288 was overexpressed or knocked down in HCC cells, cell growth was detected by the CCK-8 experiment, and cell migration was evaluated using Transwell experiment and scratch healing experiment. The targeting relationship between miR-335-5p and circ_0064288 and ROCK1 mRNA was predicted and verified using bioinformatic analysis and dual-luciferase reporter gene experiments, respectively. Western blot was executed to examine ROCK1 protein expression in HCC cells. Results Circ_0064288 and ROCK1 expression was up-modulated in HCC, while miR-335-5p was down-modulated. High circ_0064288 expression was associated with shorter survival time of HCC patients. It was also revealed that circ_0064288 overexpression remarkably enhanced HCC cell growth and migration, while knockdown of circ_0064288 induced opposite effects. Additionally, circ_0064288 could competitively bind with miR-335-5p thereby up-modulate ROCK1 expression. MiR-335-5p overexpression partly counteracted the effect of circ_0064288 overexpression on HCC cells. Conclusion Circ_0064288 facilitates HCC cell growth and migration by modulating the miR-335-5p/ROCK1 axis.

Abstract
Increasing studies have reported that circular RNAs (circRNAs) play critical roles in tumorigenesis and cancer progression. However, the underlying regulatory mechanisms of circRNA-related competing endogenous RNA (ceRNA) in liver hepatocellular carcinoma (LIHC) are still unclear. In the present study, we discovered dysregulated circRNAs through Gene Expression Omnibus (GEO) analysis and validated the expression of the top seven circRNAs with upregulated expression by qRT–PCR and Sanger sequencing. Then, the Cancer-Specific CircRNA Database (CSCD) was used to predict the downstream miRNAs of seven circRNAs, and expression and survival analyses through The Cancer Genome Atlas (TCGA) were performed to identify the key miRNA in LIHC. Thereafter, the hsa_circ_0017264-hsa-miR-195–5p subnetwork was successfully constructed. Subsequently, we predicted downstream target genes of hsa-miR-195–5p with TargetScan, miRDB, and mirtarbase and overlapped them with differentially expressed mRNAs to obtain 21 target genes. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed to predict the biological and functional roles of these target genes. Finally, with Pearson correlation and prognostic value analysis, a survival-related hsa_circ_0017264-hsa-miR-195-5p-CHEK1/CDC25A/FOXK1 axis was established. Gene set enrichment analysis (GSEA) was performed to determine the function of CHEK1/CDC25A/FOXK1 in the ceRNA network. Moreover, immune infiltration analysis revealed that the ceRNA network was markedly associated with the levels of multiple immune cell infiltrates, immune cell biomarkers and immune checkpoints. Overall, the hsa_circ_0017264-hsa-miR-195-5p-CHEK1/CDC25A/FOXK1 network might provide novel insights into the potential mechanisms underlying LIHC onset and progression.

Abstract
Background: Non-small cell lung cancer (NSCLC) is the most prevalent cancer in the world. Chemotherapy resistance is a major obstacle to NSCLC therapy. This study explored the role and molecular mechanism of circular RNA 0011292 (circ_0011292) in tumorigenesis and chemoresistance of NSCLC. Methods: The levels of circ_0011292, miR-379-5p, and tripartite motif-containing protein 65 (TRIM65) were measured by quantitative real-time polymerase chain reaction or Western blot assay. Cell proliferation was assessed by Cell Counting Kit-8 (CCK-8) assay. Cell apoptosis was monitored by flow cytometry. Cell migration and invasion were detected by transwell assay. The levels of apoptosis-related and epithelial-mesenchymal transition-related proteins were examined by Western blot. The half-inhibition concentration (IC50) of paclitaxel (PTX) was evaluated by CCK-8 assay. Xenograft model was established to analyze the effect of circ_0011292 on PTX resistance of NSCLC in vivo. The interaction among circ_0011292, miR-379-5p, and TRIM65 was verified by dual-luciferase reporter assay and RNA immunoprecipitation assay. Results: Circ_0011292 and TRIM65 were upregulated, while miR-379-5p was downregulated in NSCLC tissues and cells. Circ_0011292 knockdown hindered NSCLC progression and enhanced PTX sensitivity of NSCLC. Circ_0011292 silencing reduced PTX resistance in vivo. Besides, miR-379-5p potentiated PTX sensitivity by targeting TRIM65. Also, circ_0011292 increased PTX resistance by sponging miR-379-5p. Conclusion: Circ_0011292 facilitated tumorigenesis and PTX resistance in NSCLC by regulating the miR-379-5p/TRIM65 axis, suggesting that circ_0011292 was a promising therapeutic target for NSCLC chemotherapy.

Abstract
Circular RNAs (circRNAs) are non-coding RNAs with covalently closed structures that modulate the progression of hepatocellular carcinoma (HCC). Here, we explored whether circ_0008043 regulated the biological function of HCC cells. Quantitative real-time polymerase chain reaction (qPCR) was used to detect circ_0008043, microRNA (miR)-326, and RAB21 levels. Expression of E-cadherin, N-cadherin, and vimentin was assessed using qPCR. Cell proliferation, migration, and invasion were evaluated using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, colony formation, and transwell assays. Xenograft tumors were used to evaluate cell growth in vivo. The interaction between miR-326 and circ_0008043 or RAB21 was assessed using dual-luciferase reporter analysis and RNA pull-down analysis. The data illustrated that circ_0008043 and RAB21 were highly expressed, while miR-326 was expressed at less levels in HCC tissues and cells. Interfering with circ_0008043 suppressed cellular proliferation, migration, invasion, and cell growth. Circ_0008043 was confirmed to be an miR-326 sponge that targets RAB21. Rescue experiments showed that inhibiting miR-326 abrogated the effect induced by knockdown of circ_0008043, and overexpressed RAB21 abolished the effect induced by miR-326 overexpression. In summary, silencing of circ_0008043 impeded HCC progression by regulating the miR-326/RAB21 axis. These data suggest that circ_0008043 may have clinical value in the treatment of HCC.

Abstract
Circular RNAs (circRNAs) have been confirmed to be associated with the progression of various cancers, including hepatocellular carcinoma (HCC). However, the role and mechanism of circHIPK3 in HCC are still unclear. To investigate its function, circHIPK3 expression was first determined by RT–qPCR in HCC tissues or cells. Functionally, cell proliferation and invasion were investigated by CCK-8, EdU, or Transwell assays. In terms of understanding the mechanism, the interaction of the circRNA HIPK3/micro RNA 124 (miRNA 124) or micro RNA 506 (miRNA506) /PDK2 regulatory loop was verified by dual-luciferase reporter gene assay. In addition, a xenograft tumor model was established to confirm the impact of circHIPK3 on the growth of HCC cells in vivo. We found that circHIPK3 was upregulated in HCC patients and associated with clinical characteristics, while miR-124 and miR-506 were downregulated in HCC patients. Additionally, we proved that knock down of circHIPK3 remarkably suppressed the proliferation and invasion of HCC cells. Mechanistically, circHIPK3 directly bound to miR-124 or miR-506 and inhibited their expression, and PDK2 was a target gene of miR-124 or miR-506. Moreover, circHIPK3 overexpression reversed the inhibitory effect of miR-124 or miR-506 on HCC progression. miR-124 or miR-506 could also suppress tumorigenesis of HCC cells by PDK2. Furthermore, in vivo evidence confirmed that knock down of circHIPK3 inhibited tumor formation. We suggest that circHIPK3 can accelerate the proliferation and invasion of HCC cells by sponging miR-124 or miR-506 to upregulate PDK2, which is the underlying mechanism of circHIPK3-induced HCC progression.

Abstract
BACKGROUND Breast cancer is widespread in females. The role of circular RNA (circRNA) in breast cancer has aroused much attention. However, the function of several circRNAs remain unclear. The aim of our study was to determine the role of circ_0001955 in breast cancer. METHODS Quantitative real-time PCR (qPCR) and western blot was employed for expression analysis of circ_0001955, miR-1299 and glucose transporter 1 (GLUT1). Cell functions including proliferation, apoptosis, migration, invasion and angiogenesis, were assessed using EdU, flow cytometry, transwell and tube formation assays. Glycolysis metabolism was assessed according to glucose consumption, lactate production and ATP content. Dual-luciferase reporter assay and RIP assay were utilized to validate the binding between miR-1299 and circ_0001955 or GLUT1. The effects of circ_0001955 in vivo were observed by animal study. RESULTS Upregulation of circ_0001955 was detected in breast cancer. Knockdown of circ_0001955 inhibited breast cancer cell proliferation, migration, invasion, angiogenesis and glycolysis. MiR-1299 was a target of circ_0001955, and its repression reversed the effects of circ_0001955 knockdown. Moreover, circ_0001955 targeted miR-1299 to positively regulate GLUT1 expression. GLUT1 overexpression reversed the effects of miR-1299 enrichment. GLUT1 knockdown was verified to block tumor growth in vivo. CONCLUSIONS Circ_0001955 was found to promote breast cancer malignant development via targeting of the miR-1299/GLUT1 pathway, which contributes to our understanding of the pathogenesis of breast cancer.

Cancer Med 2022; 11:1589-1604.

Abstract
BACKGROUND Till now, no study has focused on the functions of RNASEH1 antisense RNA 1 (RNASEH1-AS1) in non-small cell lung cancer (NSCLC). Accordingly, we measured the expression of RNASEH1-AS1 in NSCLC and characterized its functions in detail. Finally, our research elucidated the mechanisms that occurred downstream of RNASEH1-AS1. METHODS RNASEH1-AS1 expression was examined utilizing TCGA database and qRT-PCR. Functional experiments were conducted to study the tumor-associated functions of RNASEH1-AS1. The targeting relationship among RNASEH1-AS1, microRNA-516a-5p (miR-516a-5p), and forkhead box K1 (FOXK1) was revealed utilizing RNA immunoprecipitation and luciferase reporter assays. RESULTS Utilizing TCGA database and our own cohort, we found a significantly increased level of RNASEH1-AS1 in NSCLC. The high level of RNASEH1-AS1 was markedly related with poor clinical outcomes. Knockdown of RNASEH1-AS1 expression inhibited NSCLC cell growth, metastatic capacities, and epithelial-mesenchymal transition and promoted the apoptosis in vitro, whereas RNASEH1-AS1 overexpression exerted the opposite effects. Additionally, knocking down RNASEH1-AS1 expression suppressed tumor growth in vivo. RNASEH1-AS1 was confirmed to act as a miR-516a-5p sponge, consequently upregulating FOXK1 expression in NSCLC cells. As revealed by the subsequent rescue experiments, the miR-516a-5p/FOXK1 axis served as a downstream effector of RNASEH1-AS1. In addition, by controlling the miR-516a-5p/FOXK1 axis, RNASEH1-AS1 was capable of activating the Wnt/β-catenin pathway. CONCLUSION RNASEH1-AS1 exacerbated the oncogenicity of NSCLC by affecting the miR-516a-5p/FOXK1 axis and consequently promoting the activation of Wnt/β-catenin pathway. Our newly identified RNASEH1-AS1/miR-516a-5p/FOXK1/Wnt/β-catenin network may offer an interesting foundation for NSCLC treatment in the clinic.

Abstract
Chemoresistance in hepatocellular carcinoma (HCC) has been found to be influenced by exosomal transport of circRNAs. However, the role of circZFR in HCC chemoresistance still remains unclear. In the present study, circZFR was highly expressed in cisplatin (DDP)-resistant HCC cell lines and could regulate DDP resistance of the HCC cells. Also, circZFR was highly expressed in cancer-associated fibroblast (CAFs) and the exosome of CAFs. In addition, supplementation of CAFs in culture medium could promote DDP resistance of HCC cells. In vivo tumor xenograft experiments showed that knockdown of circZFR inhibited tumor growth and weakened DDP resistance, while CAFs-derived exosomes incubation increased the expression of circZFR, inhibited the STAT3/NF-κB pathway, promoted tumor growth, and enhanced DDP resistance. In general, CAFs-derived exosomes deliver circZFR to HCC cells, inhibit the STAT3/NF-κB pathway, and promote HCC development and chemoresistance. The results provided a new sight for the prevention and treatment of chemoresistance in HCC.
