Yang Y, Huang K, Jiang H, Wang S, Xu X, Liu Y, Liu Q, Wei M, Li Z. Unveiling the role of circRBBP7 in myoblast proliferation and differentiation: A novel regulator of muscle development. FASEB J 2024; 38:e23808. [PMID: 38994637 DOI: 10.1096/fj.202302599rr] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 06/13/2024] [Accepted: 06/26/2024] [Indexed: 07/13/2024]
Abstract
Muscle development is a multistep process regulated by diverse gene networks, and circRNAs are considered novel regulators mediating myogenesis. Here, we systematically analyzed the role and underlying regulatory mechanisms of circRBBP7 in myoblast proliferation and differentiation. Results showed that circRBBP7 has a typical circular structure and encodes a 13 -kDa protein. By performing circRBBP7 overexpression and RNA interference, we found that the function of circRBBP7 was positively correlated with the proliferation and differentiation of myoblasts. Using RNA sequencing, we identified 1633 and 532 differentially expressed genes (DEGs) during myoblast proliferation or differentiation, respectively. The DEGs were found mainly enriched in cell cycle- and skeletal muscle development-related pathways, such as the MDM2/p53 and PI3K-Akt signaling pathways. Further co-IP and IF co-localization analysis revealed that VEGFR-1 is a target of circRBBP7 in myoblasts. qRT-PCR and WB analysis further confirmed the positive correlation between VEGFR-1 and circRBBP7. Moreover, we found that in vivo transfection of circRBBP7 into injured muscle tissues significantly promoted the regeneration and repair of myofibers in mice. Therefore, we speculate that circRBBP7 may affect the activity of MDM2 by targeting VEGFR-1, altering the expression of muscle development-related genes by mediating p53 degradation, and ultimately promoting myoblast development and muscle regeneration. This study provides essential evidence that circRBBP7 can serve as a potential target for myogenesis regulation and a reference for the application of circRBBP7 in cattle genetic breeding and muscle injury treatment.

JOURNAL OF HAZARDOUS MATERIALS 2024; 476:135212. [PMID: 39024764 DOI: 10.1016/j.jhazmat.2024.135212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 07/07/2024] [Accepted: 07/13/2024] [Indexed: 07/20/2024]
Abstract
Excessive environmental exposure to manganese (Mn) has been linked to cognitive impairments, circular RNAs (circRNAs) have been recognized for their roles in epigenetic regulation in various biological processes, including neurological pathogenesis. Previous studies found that ferroptosis, an iron ion-dependent programmed cell death, may be involved in cognitive impairments. However, specific mechanisms underlying the relationship among circRNA, ferroptosis, and neurotoxicity of Mn are not well-understood. In the current study, RNA sequencing was performed to profile RNA expression in Neuro-2a (N2a) cells that were treated with 300 μM Mn. The potential molecular mechanisms of circHmbox1(3,4) in Mn-induced cognitive impairments were investigated via various experiments, such as Western blot and intracerebroventricular injection in mice. We observed a significant decrease in the expression of circHmbox1(3,4) both in vitro and in vivo following Mn treatment. The results of Y maze test and Morris water maze test demonstrated an improvement in learning and memory abilities following circHmbox1(3,4) overexpression in Mn treated mice. Mn treatment may reduce circHmbox1(3,4) biogenesis through lowered expression of E2F1/QKI. Inhibiting circHmbox1(3,4) expression led to GPX4 protein degradation through protein ligation and ubiquitination. Overall, the current study showed that Mn exposure-induced cognitive dysfunction may be mediated through ferroptosis regulated by circHmbox1(3,4).

ENVIRONMENT INTERNATIONAL 2024; 190:108832. [PMID: 38936066 DOI: 10.1016/j.envint.2024.108832] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 05/08/2024] [Accepted: 06/17/2024] [Indexed: 06/29/2024]
Abstract
Cigarette smoke (CS), an indoor environmental pollutant, is a prominent risk factor for emphysema, which is a pathological feature of chronic obstructive pulmonary disease (COPD). Emerging function of circRNAs in immune responses and disease progression shed new light to explore the pathogenesis of emphysema. In this research, we demonstrated, by single-cell RNA sequencing (scRNAseq), that the ratio of M2 macrophages were increased in lung tissues of humans and mice with smoking-related emphysema. Further, our data showed that circADAMTS6 was associated with cigarette smoke extract (CSE)-induced M2 macrophage polarization. Mechanistically, in macrophages, circADAMTS6 stabilized CAMK2A mRNA via forming a circADAMTS6/IGF2BP2/CAMK2A RNA-protein ternary complex to activate CREB, which drives M2 macrophage polarization and leads to emphysema. In addition, in macrophages of mouse lung tissues, downregulation of circADAMTS6 reversed M2 macrophage polarization, the proteinase/anti-proteinase imbalance, and the elastin degradation, which protecting against CS-induced emphysema. Moreover, for macrophages and in a model with co-cultured lung organoids, the target of circADAMTS6 restored the growth of lung organoids compared to CSE-treated macrophages. Our results also demonstrated that, for smokers and COPD smokers, elevation of circADAMTS6 negatively correlated with lung function. Overall, this study reveals a novel mechanism for circADAMTS6-driven M2 macrophage polarization in smoking-related emphysema and postulates that circADAMTS6 could serve as a diagnostic and therapeutic marker for smoking-related emphysema.

A unique circ_0067716/EIF4A3 double-negative feedback loop impacts malignant transformation of human bronchial epithelial cells induced by benzo(a)pyrene. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 923:171349. [PMID: 38438030 DOI: 10.1016/j.scitotenv.2024.171349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 02/23/2024] [Accepted: 02/27/2024] [Indexed: 03/06/2024]
Abstract
Benzo(a)pyrene as a pervasive environmental contaminant is characterized by its substantial genotoxicity, and epidemiological investigations have established a correlation between benzo(a)pyrene exposure and the susceptibility to human lung cancer. Notably, much research has focused on the link between epigenetic alterations and lung cancer induced by chemicals, although circRNAs are also emerging as relevant contributors to the carcinogenic process of benzo(a)pyrene. In this study, we identified circ_0067716 as being significantly upregulated in response to stress injury and downregulated during malignant transformation induced by benzo(a)pyrene-7,8-diol-9,10-epoxide (BPDE) in human bronchial epithelial cells. The observed differential expression of circ_0067716 in cells treated with BPDE for varying durations suggests a strong correlation between this circRNA and BPDE exposure. The tissue samples of lung cancer patients also suggest that a lower circ_0067716 expression is associated with BPDE-DNA adduct levels. Remarkably, we demonstrate that EIF4A3, located in the nucleus, interacts with the flanking sequences of circ_0067716 and inhibits its biogenesis. Conversely, circ_0067716 is capable of sequestering EIF4A3 in the cytoplasm, thereby preventing its translocation into the nucleus. EIF4A3 and circ_0067716 can form a double-negative feedback loop that could be affected by BPDE. During the initial phase of BPDE exposure, the expression of circ_0067716 was increased in response to stress injury, resulting in cell apoptosis through the involvement of miR-324-5p/DRAM1/BAX axis. Subsequently, as cellular adaptation progressed, long-term induction due to BPDE exposure led to an elevated EIF4A3 and a reduced circ_0067716 expression, which facilitated the proliferation of cells by stabilizing the PI3K/AKT pathway. Thus, our current study describes the effects of circ_0067716 on the genotoxicity and carcinogenesis induced by benzo(a)pyrene and puts forwards to the possible regulatory mechanism on the occurrence of smoking-related lung cancer, providing a unique insight based on epigenetics.

Abstract
It has been shown that the circular RNA (circRNA) circPTK2 modulates many types of diseases. However, the possible functions as well as the molecular mechanisms of circPTK2 in preeclampsia (PE) and their effects on trophoblast are unknown. Herein, we obtained the placental tissues from 20 pregnant women with PE who delivered in the Yueyang Maternal Child Medicine Health Hospital between 2019 and 2021 to serve as the PE group, and a normal group was composed of 20 healthy pregnant women with normal prenatal examinations. The circPTK2 level was significantly reduced in tissues from the PE group. The expression and localization of circPTK2 were verified using RT-qPCR. CircPTK2 silencing inhibited HTR-8/SVneo growth and migration in vitro. To investigate the underlying mechanism of circPTK2 in PE progression, dual-luciferase reporter assays were conducted. It was found that circPTK2 and WNT7B could bind directly to miR-619, and that circPTK2 affected WNT7B expression by sponging miR-619. To conclude, this study identified the functions and mechanisms of the circPTK2/miR-619/WNT7B axis in PE progression. In this way, circPTK2 has the potential to be used both in diagnostic and therapeutic settings for PE.

Abstract
One of the most frequent environmental contaminants, benzene is still widely used as an industrial solvent around the world, especially in developing nations, posing a serious occupational risk. While the processes behind the toxicity of benzene grounds are not fully understood, it is generally accepted that its metabolism, which involves one or more reactive metabolites, is crucial to its toxicity. In order to evaluate the many ways that benzene could influence gene regulation and thus have an impact on human health, new methodologies have been created. The pathophysiology of the disorder may result from epigenetic reprogramming caused by exposure to benzene, including changes in non-coding RNA (ncRNA) markers, according to recent studies. We are interested in the identification of hazardous regulatory ncRNAs, the identification of these ncRNAs' targets, and the comprehension of the significance of these interactions in the mechanisms behind benzene toxicity. Hence, the focus of recent research is on long non-coding RNAs (lncRNAs), circular RNAs (circRNAs) and microRNAs (miRNAs), and some of the more pertinent articles are also discussed.

Abstract
Increasing evidence shows that circular RNA (circRNA) plays an important role in the progression of lung cancer. In this study, we found that has_circ_0000043 was highly expressed in 16HBE-T human bronchial epithelial cells that were malignantly transformed by benzo[a]pyrene-trans-7,8-diol-9,10-epoxide via circRNA microarray. We verified that hsa_circ_0000043 was also significantly overexpressed in lung cancer cell lines and tissues. Moreover, hsa_circ_0000043 overexpression was positively correlated with poor clinicopathological parameters, such as tumor-node metastasis stage, distant metastasis, lymph-node metastasis, and overall survival. In vitro assays revealed that hsa_circ_0000043 inhibition suppressed 16HBE-T cell proliferation, migration, and invasion. Furthermore, hsa_circ_0000043 inhibition suppressed tumor growth in a mouse xenograft model. We discovered that hsa_circ_0000043 binds with miR-4492, acting as a miR-4492 sponge. Decreased miR-4492 expression was also associated with poor clinicopathological parameters. Thus, hsa_circ_0000043 was shown to contribute to the proliferation, malignant transformation ability, migration, and invasion of 16HBE-T cells via miR-4492 sponging and BDNF and STAT3 involvement.

The regulation of circRNA_kif26b on alveolar epithelial cell senescence via miR-346-3p is involved in microplastics-induced lung injuries. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 882:163512. [PMID: 37084911 DOI: 10.1016/j.scitotenv.2023.163512] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 03/23/2023] [Accepted: 04/10/2023] [Indexed: 05/03/2023]
Abstract
Microplastics (MPs), the emerging environmental contaminants, can be inhaled and lead to lung injuries, including inflammation and fibrosis. Alveolar epithelial cell senescence is associated with several lung diseases, but its mechanism in MPs-induced lung injuries remains unknown. In this study, polystyrene microplastics (PS-MPs) in the form of microspheres with a particle size of 100 nm were used for a 35-day inhalation exposure in SPF-grade Sprague-Dawley (SD) rats. The plethysmograph showed lung dysfunction. The hematoxylin and eosin (H&E) staining revealed lung histological lesions with a significant accumulation of inflammatory cells. The β-galactosidase staining indicated increased senescent cells in lung tissues. The ELISA suggested increased senescence-associated secretory phenotype (SASP) in bronchoalveolar lavage fluid (BALF). Treatment of mouse alveolar epithelial cell line MLE12 with PS-MPs raised levels of senescence-related markers p21, p16, and p27 and SASP secretion. circ_kif26b, a ring-structured non-coding RNA (ncRNA), is homologous in human, rat, and mouse and was elevated in PS-MPs-exposed rat lung tissues as well as in PS-MPs-treated MLE12 cells. The luciferase reporter gene revealed that circ_kif26b was bound to miR-346-3p and co-regulated p21, a target gene of miR-346-3p. circ_kif26b knockdown or miR-346-3p overexpression attenuated PS-MPs-induced MLE12 cell senescence and secretion of the SASP cytokines IL-6 and IL-8. However, down-regulation of circ_kif26b and miR-346-3p reversed this depressive effect. Overall, circ_kif26b mediates alveolar epithelial cell senescence through miR-346-3p and participates in PS-MPs-induced lung inflammation. These findings provide new insights into the mechanisms of MPs inhalation toxicity and lay a mechanistic foundation for health risk assessment of MPs.

Abstract
Inflammation is a major adverse outcome induced by inhaled particulate matter with a diameter of ≤ 2.5 µm (PM2.5), and a critical trigger of most PM2.5 exposure-associated diseases. However, the key molecular events regulating the PM2.5-induced airway inflammation are yet to be elucidated. Considering the critical role of circular RNAs (circRNAs) in regulating inflammation, we predicted 11 circRNAs that may be involved in the PM2.5-induced airway inflammation using three previously reported miRNAs through the starBase website. A novel circRNA circ_0008553 was identified to be responsible for the PM2.5-activated inflammatory response in human bronchial epithelial cells (16HBE) via inducing oxidative stress. Using a combinatorial model PM2.5 library, we found that the synergistic effect of the insoluble core and loaded Zn2+ ions at environmentally relevant concentrations was the major contributor to the upregulation of circ_0008553 and subsequent induction of oxidative stress and inflammation in response to PM2.5 exposures. Our findings provided new insight into the intervention of PM2.5-induced adverse outcomes.

Abstract
Circular RNAs (circRNAs) are characterized by a covalent closed-loop structure with an absence of both 5' cap structure and 3' polyadenylated tail. Numerous studies have found that circRNAs play an important role in various diseases and have a variety of biological regulatory mechanisms, including acting as microRNA sponges, interacting with proteins, modulating the expression of related genes and translating into peptides or proteins. CircRNAs have also been used as biomarkers for a number of diseases, which could improve clinical practice. This review summarizes the most recent advances in biogenesis and knowledge of the biological functions of circRNAs as well as the related bioinformatics databases. We specifically describe developments in understanding of circRNA functions in the field of environmental exposure-induced diseases. Finally, we focus on potential clinical implications of circRNAs to facilitate their clinical transformation into disease treatment.

Abstract
Osteosarcoma is a highly malignant solid tumor with poor prognosis, early metastasis, and rapid progression and has a high mortality rate, in which better therapeutic strategies are needed. Circ0038632, also known as circPLK1, is a tumor promotor in multiple cancers. However, its biological functions and molecular regulatory mechanisms in osteosarcoma remain unclear. To ascertain the function of circ0038632 in osteosarcoma, we checked its expression in cells and in tissues and tested its abilities of proliferation and migration. Expression experiment manifested that circ0038632 showed an enhanced expression in osteosarcoma. Functional studies revealed that circ0038632 inhibition reduced cell proliferation and metastasis abilities of osteosarcoma. Mechanism studies revealed that circ0038632 sponged miR-186 to upregulate the expression of DNA methyltransferase 3A (DNMT3A) to promote osteosarcoma progression. The circ0038632/miR-186/DNMT3A axis was involved in osteosarcoma progression. The results elucidated the potential application of circ0038632 as a novel diagnostic biomarker for progressive process of osteosarcoma.

Abstract
As noncoding RNAs, circular RNAs (circRNAs) are covalently enclosed endogenous biomolecules in eukaryotes that have tissue specificity and cell specificity. circRNAs were once considered a rare splicing byproduct. With the development of high-throughput sequencing, it has been confirmed that they are expressed in thousands of mammalian genes. To date, only a few circRNA functions and regulatory mechanisms have been verified. Adipose is the main tissue for body energy storage and energy supply. Adipocyte metabolism is a physiological process involving a series of genes and affects biological activities in the body, such as energy metabolism, immunity, and signal transmission. When adipocyte formation is dysregulated, it will cause a series of diseases, such as atherosclerosis, obesity, fatty liver, and diabetes. In recent years, many noncoding RNAs involved in adipocyte metabolism have been revealed. This review provides a comprehensive overview of the basic structure and biosynthetic mechanism of circRNAs, and further discusses the circRNAs related to adipocyte formation in adipose tissue and liver. Our review will provide a reference for further elucidating the genetic regulation mechanism of circRNAs involved in adipocyte metabolism.

Abstract
Hepatocellular carcinoma (HCC) is one of the most prevalent malignant tumors worldwide. In view of the lack of early obvious clinical symptoms and related early diagnostic biomarkers with high specificity and sensitivity, most HCC patients are already at the advanced stages at the time of diagnosis, and most of them are accompanied by distant metastasis. Furthermore, the unsatisfactory effect of the follow-up palliative care contributes to the poor overall survival of HCC patients. Therefore, it is urgent to identify effective early diagnosis and prognostic biomarkers and to explore novel therapeutic approaches to improve the prognosis of HCC patients. Circular RNA (CircRNA), a class of plentiful, stable, and highly conserved ncRNA subgroup with the covalent closed loop, is dysregulated in HCC. Increasingly, emerging evidence have confirmed that dysregulated circRNAs can regulate gene expression at the transcriptional or post-transcriptional level, mediating various malignant biological behaviors of HCC cells, including proliferation, invasion, metastasis, immune escape, stemness, and drug resistance, etc.; meanwhile, they are regarded as potential biomarkers for early diagnosis and prognostic evaluation of HCC. This article reviews the research progress of circRNAs in HCC, expounding the potential molecular mechanisms of dysregulated circRNAs in the carcinogenesis and development of HCC, and discusses those application prospects in the diagnosis and prognosis of HCC.

Abstract
Fine particulate matter (PM2.5) has been shown to induce DNA damage. Circular RNAs (circRNAs) have been implicated in various disease processes related to environmental chemical exposure. However, the role of circRNAs in the regulation of DNA damage response (DDR) after PM2.5 exposure remains unclear. In this study, male ICR mice were exposed to PM2.5 at a daily mean concentration of 382.18 μg/m3 for 3 months in an enriched-ambient PM2.5 exposure system in Shijiazhuang, China, and PM2.5 collected form Shijiazhuang was applied to RAW264.7 cells at 100 µg/mL for 48 h. The results indicated that exposure to PM2.5 induced histopathological changes and DNA damage in the lung, kidney and spleen of male ICR mice, and led to decreased cell viability, increased LDH activity and DNA damage in RAW264.7 cells. Furthermore, circ_Cabin1 expression was significantly upregulated in multiple mouse organs as well as in RAW264.7 cells upon exposure to PM2.5. PM2.5 exposure also resulted in impairment of non-homologous end joining (NHEJ) repair via the downregulation of Lig4 or Dclre1c expression in vivo and in vitro. Importantly, circ_Cabin1 promoted PM2.5-induced DNA damage via inhibiting of NHEJ repair. Moreover, the expression of circ_Cabin1 and Lig4 or Dclre1c was strongly correlated in multiple mouse organs, as well as in the blood. In summary, our study provides a new perspective on circRNAs in the regulation of DDR after environmental chemical exposure.

Function of Circular RNAs in Fish and Their Potential Application as Biomarkers. Int J Mol Sci 2021; 22:ijms22137119.

Abstract
Circular RNAs (circRNAs) are an emerging class of regulatory RNAs with a covalently closed-loop structure formed during pre-mRNA splicing. Recent advances in high-throughput RNA sequencing and circRNA-specific computational tools have driven the development of novel approaches to their identification and functional characterization. CircRNAs are stable, developmentally regulated, and show tissue- and cell-type-specific expression across different taxonomic groups. They play a crucial role in regulating various biological processes at post-transcriptional and translational levels. However, the involvement of circRNAs in fish immunity has only recently been recognized. There is also broad evidence in mammals that the timely expression of circRNAs in muscle plays an essential role in growth regulation but our understanding of their expression and function in teleosts is still very limited. Here, we discuss the available knowledge about circRNAs and their role in growth and immunity in vertebrates from a comparative perspective, with emphasis on cultured teleost fish. We expect that the interest in teleost circRNAs will increase substantially soon, and we propose that they may be used as biomarkers for selective breeding of farmed fish, thus contributing to the sustainability of the aquaculture sector.

Abstract
circular RNA (circRNA) is a closed ring structure formed by cyclic covalent bonds connecting the 5’-end and 3’-end of pre-mRNA. circRNA is widely distributed in eukaryotic cells. Recent studies have shown that circRNA is involved in the pathogenesis and development of multiple types of diseases, including tumors. circRNA is specifically expressed in tissues. And the stability of circRNA is higher than that of linear RNA, which can play biological roles through sponge adsorption of miRNA, interaction with RNA binding protein, regulation of gene transcription, the mRNA and protein translation brake, and translation of protein and peptides. These characteristics render circRNAs as biomarkers and therapeutic targets of tumors. Gastrointestinal tumors are common malignancies worldwide, which seriously threaten human health. In this review, we summarize the generation and biological characteristics of circRNA, molecular regulation mechanism and related effects of circRNA in gastrointestinal tumors.

Abstract
The perturbation of intestinal microbes may serve as a mechanism by which arsenic exposure causes or exacerbates diseases in humans. However, the changes in the intestinal microbiome and metabolome induced by long-term exposure to high concentrations of arsenic have not been extensively studied. In this study, C57BL/6 mice were exposed to sodium arsenite (As) (50 ppm) for 6 months. Our results show that long-term exposure to high As concentrations changed the structure of intestinal tissues and the expression of As resistance related genes in intestinal microbes. In addition, 16S rRNA gene sequencing revealed that As exposure significantly affected the Beta diversity of intestinal flora but had no significant effect on the Alpha diversity (except ACE index). Moreover, As exposure altered the composition of the intestinal microbiota from phylum to species. Non-targeted metabolomics profiling revealed that As exposure significantly changed the composition of metabolites, specifically those related to phenylalanine metabolism. Correlation analysis demonstrated that the changes in microbial communities and metabolites were highly correlated under As exposure. Overall, this study demonstrates that long-term exposure to high As concentrations disrupted the intestinal microbiome and metabolome, which may indicate the role of As exposure at inducing human diseases under similar conditions.

Abstract
The muscle growth and development of livestock animals is a complex, multistage process, which is regulated by many factors, especially the genes related to muscle development. In recent years, it has been reported frequently that circular RNAs (circRNAs) are involved widely in cell proliferation, cell differentiation, and body development (including muscle development). However, the research on circRNAs in muscle growth and development of livestock animals is still in its infancy. In this paper, we briefly introduce the discovery, classification, biogenesis, biological function, and degradation of circRNAs and focus on the molecular mechanism and mode of action of circRNAs as competitive endogenous RNAs in the muscle development of livestock and poultry. In addition, we also discuss the regulatory mechanism of circRNAs on muscle development in livestock in terms of transcription, translation, and mRNAs. The purpose of this article is to discuss the multiple regulatory roles of circRNAs in the process of muscle development in livestock, to provide new ideas for the development of a new co-expression regulation network, and to lay a foundation for enriching livestock breeding and improving livestock economic traits.

Abstract
A previous study has elucidated that circular RNA circCLK3 acts as an oncogenic gene in cervical cancer. However, the role and regulatory mechanism of circCLK3 in tongue squamous cell carcinoma (TSCC) remain unknown. Quantitative real-time PCR was used to examine targeted gene expression in different groups. Cell viability and proliferation were investigated by MTT and 5-ethynyl-2'-deoxyuridine assays. Cell migration and invasion were detected by Transwell assays, and cell apoptosis was measured by flow cytometry analysis. The interaction among genes was investigated using luciferase reporter assay, RNA pull-down assay, and RNA immunoprecipitation assay. In the present study, our findings revealed the upregulated expression of circCLK3 in TSCC tissues and cell lines. CircCLK3 knockdown suppressed cell proliferation, migration invasion, and induced cell cycle arrest at G0/G1 phase in TSCC. Moreover, circCLK3 acted as a molecular sponge for miR-455-5p. PARVA was the target gene of miR-455-5p. Furthermore, the negative correlation between expression of miR-455-5p and circCLK3 or PARVA in TSCC tissues was discovered. Rescue assays indicated that PARVA overexpression reversed the circCLK3 knockdown-mediated inhibitory effects on the progression of TSCC. In summary, circCLK3 exerts its carcinogenic effects on TSCC progression via absorbing miR-455-5p to upregulate PARVA, which expands our knowledge on the underlying mechanism of TSCC.

Abstract
circRNAs are a class of endogenous noncoding RNA molecules with closed loop structures. They are mainly responsible for regulating gene expression in eukaryotic cells. With the emergence of high-throughput RNA sequencing (RNA-Seq) and new types of bioinformatics tools, thousands of circRNAs have been discovered, making circRNA one of the research hotspots. Recent studies have shown that circRNAs play an important regulatory role in the growth, reproduction, and formation of livestock products. They can not only regulate mammalian fetal growth and development but also have important regulatory effects on livestock muscle development and lactation. In this review, we briefly introduce the putative biogenic pathways and regulatory functions of circRNA and highlight our understanding of circRNA and its latest advances in fetal development, muscle development, and lactation biogenesis as well as expression in livestock. This review will provide a theoretical basis for the research and development of related industries.

Abstract
Hepatocellular carcinoma (HCC) is one of the main causes of tumor-related deaths worldwide. Due to the lack of obvious early symptoms and the lack of sensitive screening indicators in the early stage of HCC, the vast majority of patients are diagnosed with advanced or metastatic HCC, resulting in dissatisfactory treatment result. Therefore, it is urgent to determine effective and sensitive diagnostic and prognostic indicators and to determine new therapeutic targets. Circular RNA (circRNA) is a type of non-coding RNA that has been neglected for a long time. In recent years, it has been proved to play an important role in the development of many human diseases. Increasing evidence shows that change in circRNA expression has an extensive effect on the biological behavior of HCC. In this study, we comprehensively tracked the latest progress of circRNA in the pathogenesis of HCC, and reviewed its role as a biomarker for diagnosis and prognosis prediction in patients with HCC. In addition, we also summarized the potential of circRNA as therapeutic target in HCC and its relationship with HCC drug resistance, providing clues for the clinical development of circRNA-based therapeutic strategies.

Abstract
Cleft lip (CL) with/without cleft palate (CP) (hereafter CL/P) is the second most common congenital birth defect, affecting 7.94 to 9.92 children per 10,000 live births worldwide, followed by Down syndrome. An increasing number of genes have been identified as affecting susceptibility and/or as causative genes for CL/P in mouse genetic and chemically-induced CL and CP studies, as well as in human genome-wide association studies and linkage analysis. While marked progress has been made in the identification of genetic and environmental risk factors for CL/P, the interplays between these factors are not yet fully understood. This review aims to summarize our current knowledge of CL and CP from genetically engineered mouse models and environmental factors that have been studied in mice. Understanding the regulatory mechanism(s) of craniofacial development may not only advance our understanding of craniofacial developmental biology, but could also provide approaches for the prevention of birth defects and for tissue engineering in craniofacial tissue regeneration.

Abstract
BACKGROUND Breast cancer is the most prevalent malignancy occurring in females. In recent years, emerging evidence has suggested that circular RNAs are involved in the development of multiple cancers. Circ-PRMT5 has recently attracted attention as a tumor-promoting circular RNA. In the present study, we focused on exploring the biological effects of circ-PRMT5 in breast cancer. METHODS A quantitative real-time polymerase chain reaction was used to determine the expression of circ-PRMT5 in breast cancer. In vitro experiments, including cell-counting kit-8, 5-ethynyl-2'-deoxyuridine, flow cytometry and tube formation assays, were performed to test the effects of circ-PRMT5 on the cellular progression of breast cancer. Bioinformatic analysis, luciferase reporter, radioimmunoprecipitation and RNA-pull down assays were performed to predict the potential microRNAs interacting with circ-PRMT5 and mRNAs that can be targeted by miR-509-3p. RESULTS Circ-PRMT5 is up-regulated in breast cancer tissues and cells. Importantly, an elevation of circ-PRMT5 indicates a poor prognosis in patients with breast cancer. Functionally, knockdown of circ-PRMT5 suppresses cell proliferation and angiogenesis and increases cell apoptosis in breast cancer. Mechanistically, we identified that circ-PRMT5 up-regulates TCF7L2 expression by acting as a miR-509-3p sponge. The negative expression correlation between miR-509-3p and circ-PRMT5 or TCF7L2 in clinical tissues was further demonstrated. Rescue assays showed that TCF7L2 overexpression reverses the antitumoral effects of circ-PRMT5 knockdown on breast cancer cell processes. Additionally, we demonstrated that circ-PRMT5 activates the phosphoinositide 3-kinase (PI3K)/AKT pathway by up-regulation of TCF7L2. CONCLUSIONS Overall, our data indicate that the circ-PRMT5/miR-509-3p/TCF7L2 axis can aggravate the malignant character of breast cancer cells by the regulation of the PI3K/AKT pathway.

Abstract
N6-methyladenosine (m6A) is one of the most common RNA modifications in eukaryotes involved in the regulation of post-transcriptional gene expression, as well as the occurrence and development of diseases related to environmental exposures. Adverse factors produced by environmental exposures, such as reactive oxygen species, inflammation, and cyclobutane pyrimidine dimers, mediate m6A modification, thereby regulating downstream gene and protein expression, and signaling pathways, such as FTO/m6A RNA/p53 axis, PI3K/AKT/mTOR pathway, and PARP/METTL3/m6A RNA/Pol κ pathway. Moreover, an imbalance in m6A methylation levels directly mediates disease pathogenesis. To date, some studies have detailed the mechanisms underlying environmental exposure-mediated global changes in RNA m6A methylation. Based on our current understanding, we aimed to elaborate on the molecular mechanisms through which RNA m6A methylation regulates gene expression under environmental exposures. In this review, we outline the biogenesis and functions of RNA m6A modification. Furthermore, we focus on the effects of environmental exposures on m6A levels and highlight the relationships between environmental exposures (doses and time) and m6A levels. Although the molecular mechanisms regulating gene expression remains to be elucidated, m6A has potential applications as a disease biomarker.

Abstract
As new biomarkers, circular RNAs (circRNAs) have been largely unexplored in prostate cancer (PCa). Using an integrative approach, we aimed to evaluate the potential of circRNAs and their linear transcripts (linRNAs) to act as (i) diagnostic biomarkers for differentiation between normal and tumor tissue and (ii) prognostic biomarkers for the prediction of biochemical recurrence (BCR) after radical prostatectomy. In a first step, eight circRNAs (circATXN10, circCRIM1, circCSNK1G3, circGUCY1A2, circLPP, circNEAT1, circRHOBTB3, and circSTIL) were identified as differentially expressed via a genome-wide circRNA-based microarray analysis of six PCa samples. Additional bioinformatics and literature data were applied for this selection process. In total, 115 malignant PCa and 79 adjacent normal tissue samples were examined using robust RT-qPCR assays specifically established for the circRNAs and their linear counterparts. Their diagnostic and prognostic potential was evaluated using receiver operating characteristic curves, Cox regressions, decision curve analyses, and C-statistic calculations of prognostic indices. The combination of circATXN10 and linSTIL showed a high discriminative ability between malignant and adjacent normal tissue PCa. The combination of linGUCY1A2, linNEAT1, and linSTIL proved to be the best predictive RNA-signature for BCR. The combination of this RNA signature with five established reference models based on only clinicopathological factors resulted in an improved predictive accuracy for BCR in these models. This is an encouraging study for PCa to evaluate circRNAs and their linRNAs in an integrative approach, and the results showed their clinical potential in combination with standard clinicopathological variables.

Abstract
Exonic circular RNAs (circRNAs) have been discovered in all kingdoms of life. In many cases, the details of circRNA function and their involvement in cellular processes and diseases are not yet fully understood. However, the past few years have seen significant developments in bioinformatics and in experimental protocols that advance the ongoing research in this still-emerging field. Sophisticated methods for circRNA generation in vitro and in vivo have been developed, allowing model studies into circRNA function and application. We here review the ongoing circRNA research, giving special attention to recent progress in the field.

Abstract
Diabetic retinopathy (DR) is a frequent complication of diabetes and it can lead to visual impairment and blindness. However, the mechanism of their regulation remains little known. circRNAs can function as crucial competing endogenous RNA, which can sponge corresponding miRNAs and affect mRNA expression in various diseases, including DR. In our current research, we observed that circRNA_0084043 was elevated in high glucose (HG)-incubated ARPE-19 cells. Then, we focused on whether and how circRNA_0084043 participated in retinal vascular dysfunction under conditions diabetes. Apoptosis, inflammation and oxidative stress are hallmark of DR progression. This work was aimed to investigate the signaling mechanisms of circRNA_0084043 in these pathogenesis of DR. We discovered loss of circRNA_0084043 significantly increased cell survival and repressed HG-triggered apoptosis. In addition, knockdown of circRNA_0084043 remarkably reduced oxidative stress as evidenced by the down-regulated malondialdehyde (MDA) content, enhanced activities of Super Oxide Dismutase (SOD) and Glutathione peroxidase (GSH-PX). Addition, silence of circRNA_0084043 effectively restrained HG-stimulated inflammation as proved by repressing inflammatory cytokines Tumor Necrosis Factor α (TNF-α), Interleukin 6 (IL-6) and Cox-2 in ARPE-19 cells. Subsequently, we successfully predicted that miR-140-3p was a downstream target of circRNA_0084043, which could be negatively regulated by circRNA_0084043. Mechanistically, loss of miR-140-3p abrogated the beneficial effects of circRNA_0084043 siRNA on ARPE-19 cells. Transforming Growth Factor alpha (TGFA) can exhibit a role in multiple diseases. Taken these together, these data demonstrated that loss of circRNA_0084043 depressed HG-induced damage via sponging miR-140-3p and regulating TGFA.
