Abstract
The phosphatidyl-inositol 3-kinase/serine-threonine kinase (PI3K/ AKT) signaling pathway constitutes a classical phosphorylation cascade that integrates tyrosine, lipid, and serine acid-threonine phosphorylation, affecting cell function. The pathway is vulnerable to viral infection. Newcastle disease virus (NDV) poses a significant threat to the global poultry industry; however, its mechanism of early viral cell invasion and pathogenesis remain unclear. Previous in vivo and in vitro studies have shown that NDV infection activates PI3K/AKT signaling; however, it remains unclear whether NDV establishes infection through endocytosis regulated by this pathway. This study aimed to examine whether different genotypes of NDV strains could activate the PI3K/AKT signaling pathway within 2 h of in vitro infection. This activation, which relies on PI3K phosphorylation, remains unaffected by the phosphorylation-phosphatase and tensin homolog/phosphatase and tensin homolog (p-PTEN/PTEN) signaling pathway. Moreover, inhibition of PI3K activity impedes NDV replication. Additionally, interfering with the PI3K regulatory subunit p85 has no significant effect on NDV replication. Conversely, the tyrosine kinase activity upstream of PI3K can influence AKT activation and viral replication, particularly through vascular endothelial growth factor receptor 2 (VEGFR2). Additionally, NDV F protein primarily mediates PI3K and AKT phosphorylation to activate the PI3K/AKT signaling pathway. NDV F and VEGFR2 proteins, along with the PI3K p85α subunit, interact and co-localize at the cell membrane. NDV-induced PI3K/AKT signaling pathway activation impacts clathrin-mediated endocytosis, with VEGFR2 playing a pivotal role. In conclusion, this study shows that NDV infection is established early through F protein binding to VEGFR2, activating the PI3K/AKT signaling pathway and inducing clathrin-mediated endocytosis, supporting infection prevention and control measures. IMPORTANCE Newcastle disease virus (NDV) is a threat to the global poultry industry; however, the mechanisms of NDV infection remain unclear. NDV affects the phosphatidyl-inositol 3-kinase/serine-threonine kinase (PI3K/ AKT) signaling pathway, requiring endocytosis for successful infection. Based on previous studies, we identified a close correlation between NDV infection and replication and the PI3K/AKT signaling pathway activity. This study examined the molecular mechanisms through which NDV activates the PI3K/AKT signaling pathway to regulate endocytosis and facilitate infection. This study showed that early-stage in vitro NDV infection activated the PI3K/AKT signaling pathway, enhancing clathrin-mediated endocytosis, crucial for infection onset. Notably, this process involves the interaction between NDV F protein and the vascular endothelial growth factor receptor 2 tyrosine kinase, leading to the subsequent binding and phosphorylation of the PI3K p85α regulatory subunit. This activation primes PI3K, initiating a cascade that promotes clathrin-mediated endocytosis. Our findings elucidate how NDV capitalizes on the PI3K/AKT signaling pathway to establish infection through endocytosis.

Abstract
MicroRNAs (miRNAs) serve as key regulators in gene expression and play a crucial role in immune responses, holding a significant promise for diagnosing and managing diseases in farm animals. This review article summarizes current research on the role of miRNAs in various farm animal diseases and mycotoxicosis, highlighting their potential as biomarkers and using them for mitigation strategies. Through an extensive literature review, we focused on the impact of miRNAs in the pathogenesis of several farm animal diseases, including viral and bacterial infections and mycotoxicosis. They regulate gene expression by inducing mRNA deadenylation, decay, or translational inhibition, significantly impacting cellular processes and protein synthesis. The research revealed specific miRNAs associated with the diseases; for instance, gga-miR-M4 is crucial in Marek's disease, and gga-miR-375 tumor-suppressing function in Avian Leukosis. In swine disease such as Porcine Respiratory and Reproductive Syndrome (PRRS) and swine influenza, miRNAs like miR-155 and miR-21-3p emerged as key regulatory factors. Additionally, our review highlighted the interaction between miRNAs and mycotoxins, suggesting miRNAs can be used as a biomarker for mycotoxin exposure. For example, alterations in miRNA expression, such as the dysregulation observed in response to Aflatoxin B1 (AFB1) in chickens, may indicate potential mechanisms for toxin-induced changes in lipid metabolism leading to liver damage. Our findings highlight miRNAs potential for early disease detection and intervention in farm animal disease management, potentially reducing significant economic losses in agriculture. With only a fraction of miRNAs functionally characterized in farm animals, this review underlines more focused research on specific miRNAs altered in distinct diseases, using advanced technologies like CRISPR-Cas9 screening, single-cell sequencing, and integrated multi-omics approaches. Identifying specific miRNA targets offers a novel pathway for early disease detection and the development of mitigation strategies against mycotoxin exposure in farm animals.

Abstract
Mycoplasma gallisepticum is one of the smallest self-replicating organisms. It causes chronic respiratory disease, leading to significant economic losses in poultry industry. Following M. gallisepticum invasion, the pathogen can persist in the host owing to its immune evasion, resulting in long-term chronic infection. The strategies of immune evasion by mycoplasmas are very complex and recent research has unraveled these sophisticated mechanisms. The antigens of M. gallisepticum exhibit high-frequency changes in size and expression cycle, allowing them to evade the activation of the host humoral immune response. M. gallisepticum can invade non-phagocytic chicken cells and also regulate microRNAs to modulate cell proliferation, inflammation, and apoptosis in tracheal epithelial cells during the disease process. M. gallisepticum has been shown to transiently activate the inflammatory response and then inhibit it by suppressing key inflammatory mediators, avoiding being cleared. The regulation and activation of immune cells are important for host response against mycoplasma infection. However, M. gallisepticum has been shown to interfere with the functions of macrophages and lymphocytes, compromising their defense capabilities. In addition, the pathogen can cause immunological damage to organs by inducing an inflammatory response, cell apoptosis, and oxidative stress, leading to immunosuppression in the host. This review comprehensively summarizes these evasion tactics employed by M. gallisepticum, providing valuable insights into better prevention and control of mycoplasma infection.

Abstract
Respiratory diseases represent a significant economic and health burden worldwide, affecting millions of individuals each year in both human and animal populations. MicroRNAs (miRNAs) play crucial roles in gene expression regulation and are involved in various physiological and pathological processes. Exosomal miRNAs and cellular miRNAs have been identified as key regulators of several immune respiratory diseases, such as chronic respiratory diseases (CRD) caused by Mycoplasma gallisepticum (MG), Mycoplasma pneumoniae pneumonia (MMP) caused by the bacterium Mycoplasma pneumoniae, coronavirus disease 2019 (COVID-19), chronic obstructive pulmonary disease (COPD), asthma, and acute lung injury/acute respiratory distress syndrome (ALI/ARDS). Consequently, miRNAs seem to have the potential to serve as diagnostic biomarkers and therapeutic targets in respiratory diseases. In this review, we summarize the current understanding of the functional roles of miRNAs in the above several respiratory diseases and discuss the potential use of miRNAs as stable diagnostic biomarkers and therapeutic targets for several immune respiratory diseases, focusing on the identification of differentially expressed miRNAs and their targeting of various signaling pathways implicated in disease pathogenesis. Despite the progress made, unanswered questions and future research directions are discussed to facilitate personalized and targeted therapies for patients with these debilitating conditions.

Abstract
AbstractAvian pathogenic E. coli (APEC) is a common pathogen in the poultry industry, which can cause substantial economic losses. Recently, emerging evidence showed that the miRNAs were involved in various viral and bacterial infection. To elucidate the role of miRNAs in chicken macrophages in response to APEC infection, we attempted to investigate the miRNAs expression pattern upon APEC infection via miRNA-seq, and to identify the molecular mechanism of the important miRNAs by using RT-qPCR, Western blotting, dual-luciferase reporter assay, and CCK-8. Results showed that a total of 80 differentially expressed (DE) miRNAs were identified in the comparison of APEC vs. wild type group, which corresponded to 724 target genes. Moreover, the target genes of the identified DE miRNAs were mainly significantly enriched in MAPK signaling pathway, Autophagy-animal, mTOR signaling pathway, ErbB signaling pathway, Wnt signaling pathway, TGF-beta signaling pathway. Remarkably, gga-miR-181b-5p is capable to participate in host immune and inflammatory response against APEC infection via targeting of TGFBR1 to modulate the activation of TGF-beta signaling pathway. Collectively, this study provides a perspective of miRNA expression pattern in chicken macrophages upon APEC infection. These findings provide the insight into miRNAs against APEC infection and gga-miR-181b-5p might be a potential target for treating APEC infection.

Abstract
Avian pathogenic E. coli (APEC), one of the widespread zoonotic-pathogen, can cause a series of diseases collectively known as colibacillosis. This disease can cause thousands of million dollars economic loss each year in poultry industry and threaten to human health via meat or egg contamination. However, the detailed molecular mechanism underlying APEC infection is still not fully understood. Circular RNAs, a new type of endogenous noncoding RNA, have been demonstrated to involve in various biological processes. However, it is still not clear whether the circRNAs participate in host response against APEC infection. Herein, we utilized the high-throughput sequence technology to identify the circRNA expression profiles in APEC infected HD11 cells. A total of 49 differentially expressed (DE) circRNAs were detected in the comparison of APEC infected HD11 cells vs. wild type HD11 cells, which were involved in MAPK signaling pathway, Endocytosis, Focal adhesion, mTOR signaling pathway, and VEGF signaling pathway. Specifically, the source genes (BRAF, PPP3CB, BCL2L13, RAB11A, and TSC2) and their corresponding DE circRNAs may play a significant role in APEC infection. Moreover, based on ceRNA regulation, we constructed the circRNA-miRNA network and identified a couple of important regulatory relationship pairs related to APEC infection, including circRAB11A-gga-miR-125b-3p, circRAB11A-gga-miR-1696, and circTSC2-gga-miR-1649-5p. Results indicate that the aforementioned specific circRNAs and circRNA-miRNA network might have important role in regulating host immune response against APEC infection. This study is the first time to investigate the circRNAs expression profile and the biological function of the source genes of the identified DE circRNAs after APEC infection of chicken HD11 cells. These results would contribute to a better understanding of the molecular mechanisms in host response against APEC infection.

Abstract
Exosomes are small cell membrane-derived vesicles; they play important roles as mediators of cell-to-cell communication via delivery of their contents, such as proteins and microRNAs (miRNAs). In particular, exosomal miRNAs regulate the gene expression of recipient cells by inhibiting the expression of target mRNAs. In this study, we investigated the miRNA expression profiles of highly pathogenic avian influenza virus (HPAIV) H5N1-infected White Leghorn chickens and analyzed the functions of their target genes. After 3 d of infection with A/chicken/Vietnam/NA-01/2019 (H5N1), exosomes were isolated from the blood serum of White Leghorn chickens for small RNA sequencing. We accordingly identified 10 differentially expressed miRNAs (DE miRNAs; 5 upregulated and 5 downregulated) by comparing the exosomes derived from infected and noninfected chickens. The target genes of DE miRNAs were predicted using miRDB and TargetScan for Gene Ontology and KEGG pathway enrichment analyses. A majority of the target genes was found to be associated with the MAPK signaling pathway; several immune-related genes were identified as being regulated by these DE miRNAs. Moreover, we predicted DE miRNA binding sites in HPAIV RNA segments using the RNAhybrid algorithm. The findings of this study provide a theoretical basis for gaining insights into the regulatory mechanisms of exosomal miRNAs in response to HPAIV H5N1 infection and the identification of novel vaccine candidates.

Abstract
Pasteurella multocida (Pm) infection causes severe respiratory disease in goats. We investigated the effects of the Pm infection intratracheally on the histopathology, miRNA and mRNA expression dynamics in the lung of goats infected for 1, 2, 5 and 7 days. Pm infection caused fever, which significantly (p < 0.05) increased the body temperature of the goats from day 1 to 5. Haemotoxylin−eosin staining of the infected lung tissue showed characteristics of suppurative pneumonia with inflammatory cells infiltration and the lung structure destruction. During the Pm infection of the goats, compared with the control group, there were 3080, 3508, 2716 and 2675 differentially expressed genes and 42, 69, 91 and 108 significantly expressed miRNAs (|log2Fold Change| > 1, p < 0.05) in the Pm_d1, Pm_d2, Pm_d5 and Pm_d7 groups, respectively. Five miRNAs and nine immune-related genes were selected for confirmation by reverse transcription−polymerase chain reaction. The results indicated that the expression patterns of the miRNAs and genes were consistent with those determined by next-generation sequencing. The differentially expressed genes were enriched in cytokine−cytokine receptor interaction, cell adhesion molecules, complement and coagulation cascades, tight junction and phagosome Kyoto Encyclopedia of Genes and Genomes pathways and cytokine production, leukocyte migration, myeloid leukocyte migration, cell periphery, plasma membrane, extracellular region part, extracellular region and other Gene Ontology terms. The differentially expressed genes were mapped to marker genes in human and mouse lung cells. The results showed the presence of some marker genes of the immune cells. Compared with the CK group, five miRNAs and 892 common genes were differentially expressed in the Pm_d1, Pm_d2, Pm_d5 and Pm_d7 groups. The target relationships between the common 5 miRNAs and 892 differentially expressed genes were explored and the miRNAs involved in the host immune reaction may act through the target genes. Our study characterized goats’ reaction in the lung from histopathological and molecular changes upon Pm infection, which will provide valuable information for understanding the responses in goats during Pm infection.

Expression Profiles of Exosomal MicroRNAs Derived from Cerebrospinal Fluid in Patients with Congenital Hydrocephalus Determined by MicroRNA Sequencing. DISEASE MARKERS 2022; 2022:5344508. [PMID: 35371347 PMCID: PMC8966745 DOI: 10.1155/2022/5344508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 01/07/2022] [Accepted: 01/11/2022] [Indexed: 11/18/2022]
Abstract
Purpose. Congenital hydrocephalus is one of the most common birth defects worldwide. Exosomal microRNAs (miRNAs) in body fluids have been implicated in many diseases. However, their involvement in cerebrospinal fluid from congenital hydrocephalus is not well understood. This study is aimed at investigating the role of dysregulated exosomal miRNAs in congenital hydrocephalus. Methods. We collected cerebrospinal fluid samples from 15 congenital hydrocephalus patients and 21 control subjects. We used miRNA sequencing to generate exosomal miRNA expression profiles in three pairs of samples. We identified 31 differentially expressed exosomal miRNAs in congenital hydrocephalus and predicted their target mRNAs. Results. Three microRNAs (hsa-miR-130b-3p, hsa-miR-501-5p, and hsa-miR-2113) were selected according to their fold changes and the function of their target mRNAs, and only hsa-miR-130b-3p and hsa-miR-501-5p were confirmed their expression levels in all samples. Moreover, upregulated hsa-miR-130b-3p might mediate the downregulation of the phosphatase and tensin homolog gene (PTEN), which has been associated with hydrocephalus, via binding to its 3
-untranslated region by dual-luciferase reporter assay. Conclusion. This study implicates that abnormally expressed exosomal miRNAs in cerebrospinal fluid may be involved in the pathomechanism of congenital hydrocephalus.

[PMID: 34554275 DOI: 10.1007/s00011-021-01499-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 07/21/2021] [Accepted: 09/02/2021] [Indexed: 10/20/2022] Open
Abstract
OBJECTIVE Mycoplasma gallisepticum (MG), a notorious avian pathogen, leads to considerable economic losses in the poultry industry. MG infection is characterized by severe, uncontrollable inflammation and host DNA damage. Micro ribonucleic acids (miRNAs) have emerged as important regulators in microbial pathogenesis. However, the role of miRNAs in MG infection is poorly characterized. In this study, we validated the functional roles of gga-miR-142-3p. METHODS The relative expression of gga-miR-142-3p in the lungs of the MG-infected chicken embryos and the MG-infected chicken embryonic fibroblast cell line (DF-1) was determined by reverse transcription quantitative real-time PCR analysis. Bioinformatics database was used to analysis the target gene of gga-miR-142-3p. The luciferase reporter assay as well as gene expression analysis were conducted to validate the target gene. To further explore the biological functions of gga-miR-142-3p upon MG infection, the cell proliferation was quantified using Cell Counting Kit-8 (CCK-8). Meanwhile, cell cycle analysis and apoptosis were measured using a flow cytometer. RESULTS gga-miR-142-3p was significantly upregulated in both MG-infected chicken-embryo lungs and the DF-1 cells. gga-miR-142-3p over expression significantly downregulated the expression of pro-inflammatory cytokines, including interleukin-1β, interleukin-6 and tumor necrosis factor alpha after MG infection. Meanwhile, gga-miR-142-3p enhanced the host defense against MG infection by facilitating cell proliferation, promoting cell progression and inhibiting cell apoptosis. Interestingly, TAB2 knockdown groups show similar results, whereas, TAB2 over-expression groups and gga-miR-142-3p inhibitor groups had thoroughly opposite results. The expression of p-p65 in nuclear factor kappa B (NF-κB) and p-p38 in the mitogen-activated protein kinase (MAPK) pathway was decreased when gga-miR-142-3p was over-expressed. CONCLUSION Upon MG infection, upregulation of gga-miR-142-3p alleviates inflammation by negatively regulating the signaling pathways of NF-κB and MAPKs by targeting TAB2 and facilitates cell proliferation by inhibiting cell apoptosis and promoting cell cycle progression to defend against MG infection.

Abstract
Mycoplasma gallisepticum (M. gallisepticum) is the primary agent of chronic respiratory disease causing important economic losses in the poultry industry. Compared to antibodies, aptamers used to diagnose M. gallisepticum have many advantages, such as being chemically, animal-free produced and easily modifiable without affecting their affinity. Herein, a single-stranded DNA (ssDNA) aptamer Apt-236 which can specifically bind to PvpA protein of M. gallisepticum with a Kd of 1.30 ± 0.18 nM was selected successfully. An indirect blocking ELAA (ib-ELAA) for M. gallisepticum antibodies detection was also developed using Apt-236, in which M. gallisepticum antibodies would block the binding-position of aptamers. Therefor positive sera would prevent color development whereas negative sera will allow a strong color reaction. The ib-ELAA was consistent with other three widely used assays in terms of the growth and decline of the antibody response to M. gallisepticum, and showed substantial agreement with the results obtained using a commercial ELISA kit in clinical chicken sera samples. Therefore, the ib-ELAA developed in this study was a new format for aptamer application and would be an alternative method for the surveillance of M. gallisepticum.

Int J Mol Med 2021; 48:141.

Abstract
Diabetic encephalopathy (DE) is one of the main chronic complications of diabetes, and is characterized by cognitive defects. MicroRNAs (miRNAs/miRs) are widely involved in the development of diabetes-related complications. The present study evaluated the role of miR-130b in DE and investigated its mechanisms of action. PC12 cells and hippocampal cells were exposed to a high glucose environment to induce cell injuries to mimic the in vitro model of DE. Cells were transfected with miR-130b mimic, miR-130b inhibitor and small interfering RNA (si)-phosphatase and tensin homolog (PTEN) to evaluate the protective effect of the miR-130b/PTEN axis against oxidative stress in high glucose-stimulated cells involving Akt activity. Furthermore, the effect of agomir-130b was also assessed on rats with DE. The expression of miR-130b was reduced in the DE models in vivo and in vitro. The administration of miR-130b mimic increased the viability of high glucose-stimulated cells, prevented apoptosis, increased the activity of superoxide dismutase (SOD), decreased the malondialdehyde (MDA) content, activated Akt protein levels and inhibited the mitochondria-mediated apoptotic pathway. The administration of miR-130b inhibitor exerted opposite effects, while si-PTEN reversed the effects of miR-130b inhibitor. In vivo, the administration of agomir-130b attenuated cognitive disorders and neuronal damage, increased SOD activity, reduced the MDA content, activated Akt protein levels and inhibited the mitochondria-mediated apoptosis pathway in rats with DE. On the whole, these results suggest that miR-130b activates the PI3K/Akt signaling pathway to exert protective effects against oxidative stress injury via the regulation of PTEN in rats with DE.

Abstract
Redox biology is a very quickly developing area of modern biological sciences, and roles of redox homeostasis in health and disease have recently received tremendous attention. There are a range of redox pairs in the cells/tissues responsible for redox homeostasis maintenance/regulation. In general, all redox elements are interconnected and regulated by various means, including antioxidant and vitagene networks. The redox status is responsible for maintenance of cell signaling and cell stress adaptation. Physiological roles of redox homeostasis maintenance in avian species, including poultry, have received limited attention and are poorly characterized. However, for the last 5 years, this topic attracted much attention, and a range of publications covered some related aspects. In fact, transcription factor Nrf2 was shown to be a master regulator of antioxidant defenses via activation of various vitagenes and other protective molecules to maintain redox homeostasis in cells/tissues. It was shown that Nrf2 is closely related to another transcription factor, namely, NF-κB, responsible for control of inflammation; however, its roles in poultry have not yet been characterized. Therefore, the aim of this review is to describe a current view on NF-κB functioning in poultry with a specific emphasis to its nutritional modulation under various stress conditions. In particular, on the one hand, it has been shown that, in many stress conditions in poultry, NF-κB activation can lead to increased synthesis of proinflammatory cytokines leading to systemic inflammation. On the other hand, there are a range of nutrients/supplements that can downregulate NF-κB and decrease the negative consequences of stress-related disturbances in redox homeostasis. In general, vitagene-NF-κB interactions in relation to redox balance homeostasis, immunity, and gut health in poultry production await further research.

Abstract
Aims Acute lung injury (ALI) is a clinical syndrome with high morbidity and mortality, and severe pulmonary edema is one of the characteristics. Epithelial sodium channel (ENaC) located on the apical side of alveolar type 2 epithelial (AT2) cells is the primary rate limiting segment in alveolar fluid clearance. Many preclinical studies have revealed that mesenchymal stem cells (MSCs) based therapy has great therapeutic potential for ALI, while the role of ENaC in this process is rarely known. Methods We studied the effects of bone marrow-derived MSCs (BMSCs) on the protein/mRNA expression and activity of ENaC in primary mouse AT2 and human H441 cells by co-culture with them, respectively. Moreover, the changes of miRNA-130b in AT2 cells were detected by qRT-PCR, and we studied the involvement of phosphatase and tensin homolog deleted on chromosome ten (PTEN) and the downstream PI3K/AKT pathway in the miRNA-130b regulation of ENaC. Results Our results demonstrated that BMSCs could increase ENaC protein expression and function, as well as the expression level of miRNA-130b. The dual luciferase target gene assay verified that PTEN was one of the target genes of miR-130b, which showed adverse effects on the protein expression of α/γ-ENaC and PTEN in AT2 cells. Upregulating miR-130b and/or knocking down PTEN resulted in the increase of α/γ-ENaC protein level, and the protein expression of p-AKT/AKT was enhanced by miR-130b. Both α and γ-ENaC protein expressions were increased after AT2 cells were transfected with siPTEN, which could be reversed by the co-administration of PI3K/AKT inhibitor LY294002. Conclusion In summary, miRNA-130b in BMSCs can enhance ENaC at least partially by targeting PTEN and activating PI3K/AKT pathway, which may provide a promising new direction for therapeutic strategy in ALI.

Abstract
Mycoplasma gallisepticum (MG) infection is the main cause of chronic respiratory disease (CRD) characterized by severe respiratory inflammation in chickens. Polydatin (PD) is a resveratrol glycoside isolated from Polygonum cuspidatum, which has prominent anti-inflammatory effect. The purpose of this study was to investigate the therapeutic effect of PD against MG-induced inflammation in chicken and its underlying mechanism. Histopathological analysis showed that PD treatment (15, 30, and 45 mg/kg) apparently alleviated MG-induced pathological changes of chicken embryonic lung. In chicken embryo fibroblast (DF-1) cells, PD treatment (15, 30, and 60 μg/mL) could effectively suppress MG propagation, promote MG-infected cell proliferation and cell cycle progress, and inhibit MG-induced cell apoptosis. ELISA and qPCR assays showed that PD treatment significantly suppressed the expression of interleukin-6 (IL-6), IL-1β and tumor necrosis factor-α (TNF-α) induced by MG both in vivo and in vitro. Besides, molecular studies indicated that the MG-induced levels of toll-like receptor-6 TLR6, myeloid differentiation-88 (MyD88) and nuclear factor κB (NF-κB) were significantly decreased by PD treatment. Moreover, immunofluorescence analysis showed that PD treatment restrained the MG-induced NF-κB-p65 nuclear translocation. Taken together, these results indicate the protective effects of PD against MG-induced inflammation injury in chicken were mainly by inhibiting the TLR6/MyD88/NF-κB pathway.

Abstract
Background Trophoblast cell surface antigen 2 (TROP2) is overexpressed in many squamous cell carcinomas and promotes tumor development and invasion. The association between TROP2 expression and occurrence and development of oral squamous cell carcinoma (OSCC) remains to be understood. Methods We investigated the role of TROP2 in OSCC patients using a combination of biophysical approaches. A total of 108 OSCC patient specimens with varying degrees of differentiation were subjected to hematoxylin and eosin staining, immunohistochemistry, Kaplan-Meier survival curve analysis, and atomic force microscopy to analyze TROP2 expression, morphology, and mechanical properties of OSCC tissues. Results TROP2 was overexpressed in 34% of poorly differentiated OSCC samples. High levels of TROP2 were associated with 10.2% survival rate lower than 45.4% and patient age (odds ratio [OR] = 0.437, P = 0.039, 95% confidence interval [CI, 0.198–0.966]), tumor size (OR = 13.148, P = 0.000, 95% CI [5.060–34.168]), and TNM stage (OR = 0.141, P = 0.000, 95% CI [0.082–0.244]). Average surface roughness of low, medium, and highly differentiated OSCC tissues were 448.9 ± 54.8, 792.7 ± 83.6, and 993.0 ± 104.3 nm, respectively. The Pearson coefficient revealed a negative association between tumor stiffness and TROP2 expression (r = − 0.84, P < 0.01). Conclusion Overexpression of TROP2 negatively associated with patient survival, degree of tumor differentiation, and tissue mechanics. Taken together, our findings demonstrated that TROP2 may be an indicator of OSCC differentiation leading to the altered mechanical properties of OSCC tissues.

Zheng S, Wang S, Zhang Q, Zhang Z, Xu S. Avermectin inhibits neutrophil extracellular traps release by activating PTEN demethylation to negatively regulate the PI3K-ERK pathway and reducing respiratory burst in carp. JOURNAL OF HAZARDOUS MATERIALS 2020; 389:121885. [PMID: 31879111 DOI: 10.1016/j.jhazmat.2019.121885] [Citation(s) in RCA: 53] [Impact Index Per Article: 13.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/14/2019] [Revised: 11/25/2019] [Accepted: 12/10/2019] [Indexed: 06/10/2023]
Abstract
Excessive residual avermectin (AVM) in the environment can have toxic effects on non-target organisms. AVM can exert immunotoxicity by inducing genomic demethylation, but its effect on neutrophil extracellular traps (NETs) release in carp is unclear. In this study, carp neutrophils were pretreated with 5 μg/L AVM or 4 μM DNA demethylation inhibitor (aurintricarboxylic acid, ATA), alone or in combination, and then treated with 4 μM phorbol 12-myristate 13-acetate (PMA) to stimulate NETs release. The results showed that exposure of carp neutrophils to AVM significantly suppressed NETs release and MPO expression, increased ROS production, and dramatically reduced PMA-induced cellular respiratory burst. In addition, AVM could bind to the MBD2 molecule, markedly upregulate MBD2 expression to cause demethylation, and clearly activate PTEN expression, thereby inhibiting the expression of PI3K, AKT, Raf, MEK, and ERK. However, these effects were alleviated by ATA. In conclusion, our study showed that AVM could inhibit NETs release in carp by inducing demethylation of PTEN to negatively regulate NETs synthesis pathways and reducing respiratory burst level. Our findings clarify the mechanism of AVM immunotoxicity to fish and are of great significance for efforts to protect the ecological environment and human health.

Effects of Mycoplasmas on the Host Cell Signaling Pathways. Pathogens 2020; 9:pathogens9040308.

Abstract
Mycoplasmas are the smallest free-living organisms. Reduced sizes of their genomes put constraints on the ability of these bacteria to live autonomously and make them highly dependent on the nutrients produced by host cells. Importantly, at the organism level, mycoplasmal infections may cause pathological changes to the host, including cancer and severe immunological reactions. At the molecular level, mycoplasmas often activate the NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) inflammatory response and concomitantly inhibit the p53-mediated response, which normally triggers the cell cycle and apoptosis. Thus, mycoplasmal infections may be considered as cancer-associated factors. At the same time, mycoplasmas through their membrane lipoproteins (LAMPs) along with lipoprotein derivatives (lipopeptide MALP-2, macrophage-activating lipopeptide-2) are able to modulate anti-inflammatory responses via nuclear translocation and activation of Nrf2 (the nuclear factor-E2-related anti-inflammatory transcription factor 2). Thus, interactions between mycoplasmas and host cells are multifaceted and depend on the cellular context. In this review, we summarize the current information on the role of mycoplasmas in affecting the host’s intracellular signaling mediated by the interactions between transcriptional factors p53, Nrf2, and NF-κB. A better understanding of the mechanisms underlying pathologic processes associated with reprogramming eukaryotic cells that arise during the mycoplasma-host cell interaction should facilitate the development of new therapeutic approaches to treat oncogenic and inflammatory processes.

Abstract
Mycoplasma gallisepticum (MG) can cause chronic respiratory disease (CRD) in chickens. While several studies have reported the inflammatory functions of microRNAs during MG infection, the mechanism by which exosomal miRNAs regulate MG-induced inflammation remains to be elucidated. The expression of exosome-microRNA derived from MG-infected chicken type II pneumocytes (CP-II) was screened, and the target genes and function of differentially expressed miRNAs (DEGs) were predicted. To verify the role of exosomal gga-miR-451, Western blot, ELISA and RT-qPCR were used in this study. The results showed that a total of 722 miRNAs were identified from the two exosomal small RNA (sRNA) libraries, and 30 miRNAs (9 up-regulated and 21 down-regulated) were significantly differentially expressed. The target miRNAs were significantly enriched in the treatment group, such as cell cycle, Toll-like receptor signalling pathway and MAPK signalling pathway. The results have also confirmed that gga-miR-451-absent exosomes derived from MG-infected CP-II cells increased inflammatory cytokine production in chicken fibroblast cells (DF-1), and wild-type CP-II cell-derived exosomes displayed protective effects. Collectively, our work suggests that exosomes from MG-infected CP-II cells alter the dynamics of the DF-1 cells, and may contribute to pathology of the MG infection via exosomal gga-miR-451 targeting YWHAZ involving in inflammation.

Contributions of Gene Modules Regulated by Essential Noncoding RNA in Colon Adenocarcinoma Progression. BIOMED RESEARCH INTERNATIONAL 2020; 2020:8595473. [PMID: 32280704 PMCID: PMC7128050 DOI: 10.1155/2020/8595473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/15/2019] [Revised: 02/26/2020] [Accepted: 03/04/2020] [Indexed: 11/17/2022]
Abstract
Noncoding RNAs (ncRNAs), especially microRNA (miRNA) and long noncoding RNA (lncRNA), have an impact on a variety of important biological processes during colon adenocarcinoma (COAD) progression. This includes chromatin organization, transcriptional and posttranscriptional regulation, and cell-cell signaling. The aim of this study is to identify the ncRNA-regulated modules that accompany the progression of COAD and to analyze their mechanisms, in order to screen the potential prognostic biomarkers for COAD. An integrative molecular analysis was carried out to identify the crosstalks of gene modules between different COAD stages, as well as the essential ncRNAs in the posttranscriptional regulation of these modules. 31 ncRNA regulatory modules were found to be significantly associated with overall survival in COAD patients. 17 out of the 31 modules (in which ncRNAs played essential roles) had improved the predictive ability for COAD patient survival compared to only the mRNAs of those modules, which were enriched in the core cancer hallmark pathways with closer interactions. These suggest that the ncRNAs' regulatory modules not only exhibit close relation to COAD progression but also reflect the dynamic significant crosstalk of genes in the modules to the different malignant extent of COAD.

Vet Res 2020; 51:8. [PMID: 32014061 PMCID: PMC6998359 DOI: 10.1186/s13567-020-0736-x] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Accepted: 12/27/2019] [Indexed: 02/07/2023] Open
Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that contribute to host immune response as post-transcriptional regulation. The current study investigated the biological role of the chicken (Gallus gallus) microRNA-200a-3p (gga-miR-200a-3p), using 2 necrotic enteritis (NE) afflicted genetically disparate chicken lines, 6.3 and 7.2, as well as the mechanisms underlying the fundamental signaling pathways in chicken. The expression of gga-miR-200a-3p in the intestinal mucosal layer of NE-induced chickens, was found to be upregulated during NE infection in the disease-susceptible chicken line 7.2. To validate the target genes, we performed an overexpression analysis of gga-miR-200a-3p using chemically synthesized oligonucleotides identical to gga-miR-200a-3p, reporter gene analysis including luciferase reporter assay, and a dual fluorescence reporter assay in cultured HD11 chicken macrophage cell lines. Gga-miR-200a-3p was observed to be a direct transcriptional repressor of ZAK, MAP2K4, and TGFβ2 that are involved in mitogen-activated protein kinase (MAPK) pathway by targeting the 3′-UTR of their transcripts. Besides, gga-miR-200a-3p may indirectly affect the expression of protein kinases including p38 and ERK1/2 at both transcriptional and translational levels, suggesting that this miRNA may function as an important regulator of the MAPK signaling pathway. Proinflammatory cytokines consisting of IL-1β, IFN-γ, IL-12p40, IL-17A, and LITAF belonging to Th1 and Th17-type cytokines, were upregulated upon gga-miR-200a-3p overexpression. These findings have enhanced our knowledge of the immune function of gga-miR-200a-3p mediating the chicken immune response via regulation of the MAPK signaling pathway and indicate that this miRNA may serve as an important biomarker of diseases in domestic animals.

Abstract
MicroRNAs (miRNAs) are small, non-coding RNA molecules that inhibit protein translation from target mRNAs. Accumulating evidence suggests that miRNAs can regulate a broad range of biological pathways, including cell differentiation, apoptosis, and carcinogenesis. With the development of miRNAs, the investigation of miRNA functions has emerged as a hot research field. Due to the intensive farming in recent decades, chickens are easily influenced by various pathogen transmissions, and this has resulted in large economic losses. Recent reports have shown that miRNAs can play critical roles in the regulation of chicken diseases. Therefore, the aim of this review is to briefly discuss the current knowledge regarding the effects of miRNAs on chickens suffering from common viral diseases, mycoplasmosis, necrotic enteritis, and ovarian tumors. Additionally, the detailed targets of miRNAs and their possible functions are also summarized. This review intends to highlight the key role of miRNAs in regard to chickens and presents the possibility of improving chicken disease resistance through the regulation of miRNAs.

Abstract
Mycoplasma bovis (M. bovis) causes diseases such as arthritis, pneumonia, abortion, and mastitis, leading to great losses in the bovine dairy industries. RNA types such as messenger RNAs (mRNAs) and long non-coding RNAs (lncRNAs) play significant roles in regulating the immune responses triggered by bacteria. The expression profiles of mRNA and lncRNA as they occur in bovine mammary gland tissues infected with M. bovis are still not well understood. To illuminate this issue, transcription analysis of mRNA and LncRNAs were conducted on the mammary gland tissues belonging to Holstein cattle infected and not infected with M. bovis. The analysis revealed 1310 differentially expressed mRNAs and 57 differentially expressed lncRNAs in the bovine mammary gland tissues infected and not infected with M. bovis. In addition, 392 novel lncRNAs were detected, 19 of which were differentially expressed. Gene ontology analysis reveals that differentially expressed mRNAs and lncRNAs play significant roles in such vital biological pathways as metabolic pathways, T-cell receptor signaling, TGF-beta signaling, pathways in cancer, PI3K-Akt signaling, NF-kappa B signaling, mTOR signaling, and apoptosis, including in the immune response to cancer. Based on our literature review, this study is the first genome-wide lncRNA research conducted on bovine mammary gland tissues infected with M. bovis. Our results provide bovine mammary gland lncRNA and mRNA resources to understand their roles in the regulation of the immune response against the agent M. bovis in bovine mammary gland tissues.

Abstract
Most malignant neoplasms of the oral cavity are oral squamous cell carcinoma (OSCC), which is a type of highly malignant tumor with a propensity for forming distant metastases. Trophoblast cell surface antigen 2 (TROP2) is a transmembrane protein that is overexpressed in several types of tumor cells, although its role and regulatory mechanism in OSCC have not been determined. The aim of the present study was to examine the effects of TROP2 in human OSCC cell lines. The present study demonstrated that TROP2 protein expression was upregulated in OSCC cell lines. Transfection of short hairpin RNA (shRNA) targeting TROP2 (sh‑TROP2) reduced cell proliferation, migration and invasion of OSCC cell lines, whereas overexpression of TROP2 increased proliferation, migration and invasion. sh‑TROP2 transfection in OSCC cell lines inhibited tumor growth in OSCC mouse models. Furthermore, TROP2 expression activated the phosphoinositide 3‑kinase (PI3K)/Akt signaling pathway in human OSCC cells. These results suggest that TROP2 induces cell growth, migration and invasion through activation of the PI3K/Akt signaling pathway in OSCC cells.

Int J Mol Sci 2019; 20:ijms20051036.

Abstract
Mycoplasma gallisepticum (MG) mainly infects chickens to initiate chronic respiratory disease (CRD). microRNAs (miRNAs) play vital roles according to previously reported studies. Our previous study showed that gga-miR-16-5p, in MG-infected lungs of chicken embryo, was upregulated by Illumina sequencing. The study aimed to reveal what role gga-miR-16-5p plays in CRD progression. gga-miR-16-5p was upregulated in MG-infected fibroblast cells (DF-1). Phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1) was demonstrated as the target gene of gga-miR-16-5p. Furthermore, PIK3R1 expression was lower in MG-infected groups than it in noninfected controls measured by qPCR. Additionally, overexpressed gga-miR-16-5p could downregulate PIK3R1 and phosphorylated serine/threonine kinase (p-Akt) to express protein, whereas there is an opposite effect on inhibition. Overexpressed gga-miR-16-5p resulted in decreased activity of tumor necrosis factor alpha (TNF-α) and the nuclear factor-kappaB (NF-κB) by qPCR. Furthermore, overexpressed gga-miR-16-5p restricted cell multiplication, cycle progression, and increased apoptosis of MG-infected DF-1 cells, whereas inhibited gga-miR-16-5p led to the opposite effect. Collectively, upregulated gga-miR-16-5p could decrease multiplication, cycle progression, and increase apoptosis of MG-infected DF-1 cells, at least partly through directly targeting PIK3R1 and inhibiting PI3K/Akt/NF-κB pathway to exert an anti-inflammatory effect. Our results will provide more experimental evidence to bring pathogenesis of MG infection to light.

Abstract
OBJECTIVE The aim of this study was to explain the effects of curcumin to depress gastric cancer biological activity by regulation miRNA-21 an in in vitro study. METHODS Collecting 30 pairs of adjacent and cancer tissues to measure miRNA-21 expression by ISH, evaluating pathology by H&E staining and measuring PTEN protein expression by IHC. Evaluating curcumin anti-tumor and correlation between curcumin and miRNA-21 in gastric cancer cell line (AGS) biological activities by CCK-8, flow cytometry, transwell, scratch test, transmission electron microscope, and western blot. RESULTS Compared with adjacent normal tissues, the miRNA-21 and PTEN expressions of gastric cancer tissues were significantly different (P < 0.001, respectively). By cell experiments, compared with NC group, the AGS cell proliferation was significantly depressed with significantly increasing cell apoptosis by keeping cell cycle in G1 phase (P < 0.001, respectively), and AGS cell invasion and migration were significantly down-regulated (P < 0.001, respectively) in Cur and Cur+BL groups. However, with miRNA-21 supplementation, the AGS cell biological activities were significantly recovered (P < 0.001, respectively). By western blot, compared with the NC group, the PTEN and P21 proteins expressions were significantly up-regulated (P < 0.001, respectively) and the PI3K, AKT, MMP-2 and MMP-9 proteins expressions were significantly down-regulated (P < 0.001, respectively). PTEN, PI3K, AKT, P21, MMP-2 and MMP-9 proteins were significantly decreased with miRNA-21 supplementation (P < 0.001, respectively). CONCLUSION Curcumin had anti-tumor effects to gastric cancer via ion of miRNA-21 by regulation of the PTEN/PI3K/AKT pathway.

Abstract
Long non-coding RNAs (lncRNAs) have been demonstrated to be involved in the development and progression of multiple cancers by previous studies. Recently, a novel lncRNA, THOR (testis-associated highly conserved oncogenic long non-coding RNA), was characterized in human cancers and shown to exhibit an oncogenic role. However, the role of THOR in hepatocellular carcinoma (HCC) is still unclear. In this study, we found that THOR was relatively highly expressed in human HCC tissues and cell lines. Notably, high THOR expression was associated with worse prognosis. THOR depletion resulted in significant inhibition of the growth and metastasis of HCC cells. Mechanistically, THOR drives HCC cell progression via the PTEN/AKT pathway. Moreover, the specific PI3-K inhibitor LY294002 abolished the discrepancy in the growth and metastatic capacity between THOR-silenced HCC cells and control cells, which further confirmed that AKT was required in THOR-driven HCC cell growth and metastasis. Taken together, our results suggest that THOR could promote HCC cell growth and metastasis by amplifying PTEN/AKT signaling and may be a new therapeutic target and predictive factor for HCC.
