The NP protein of Newcastle disease virus dictates its oncolytic activity by regulating viral mRNA translation efficiency. PLoS Pathog 2024; 20:e1012027. [PMID: 38377149 PMCID: PMC10906838 DOI: 10.1371/journal.ppat.1012027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 03/01/2024] [Accepted: 02/05/2024] [Indexed: 02/22/2024] Open
Abstract
Newcastle disease virus (NDV) has been extensively studied as a promising oncolytic virus for killing tumor cells in vitro and in vivo in clinical trials. However, the viral components that regulate the oncolytic activity of NDV remain incompletely understood. In this study, we systematically compared the replication ability of different NDV genotypes in various tumor cells and identified NP protein determines the oncolytic activity of NDV. On the one hand, NDV strains with phenylalanine (F) at the 450th amino acid position of the NP protein (450th-F-NP) exhibit a loss of oncolytic activity. This phenotype is predominantly associated with genotype VII NDVs. In contrast, the NP protein with a leucine amino acid at this site in other genotypes (450th-L-NP) can facilitate the loading of viral mRNA onto ribosomes more effectively than 450th-F-NP. On the other hand, the NP protein from NDV strains that exhibit strong oncogenicity interacts with eIF4A1 within its 366-489 amino acid region, leading to the inhibition of cellular mRNA translation with a complex 5' UTR structure. Our study provide mechanistic insights into how highly oncolytic NDV strains selectively promote the translation of viral mRNA and will also facilitate the screening of oncolytic strains for oncolytic therapy.

Abstract
As an important structural protein in virion morphogenesis, the matrix (M) protein of Newcastle disease virus (NDV) is demonstrated to be a nuclear-cytoplasmic trafficking protein and plays essential roles in viral assembly and budding. In recent years, increasing lines of evidence have indicated that the M protein has obvious influence on the pathotypes of NDV, and the interaction of M protein with cellular proteins is also closely associated with the replication and pathogenicity of NDV. Although substantial progress has been made in the past 40 years towards understanding the structure and function of NDV M protein, the available information is scattered. Therefore, this review article summarizes and updates the research progress on the structural feature, virulence and pathotype correlation, and nucleocytoplasmic transport mechanism of NDV M protein, as well as the functions of M protein and cellular protein interactions in M's intracellular localization, viral RNA synthesis and transcription, viral protein synthesis, viral immune evasion, and viral budding and release, which will provide an in-depth understanding of the biological functions of M protein in the replication and pathogenesis of NDV, and also contribute to the development of effective antiviral strategies aiming at blocking the early or late steps of NDV lifecycles.

[PMID: 37277829 DOI: 10.1186/s13567-023-01174-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Accepted: 04/28/2023] [Indexed: 06/07/2023] Open
Abstract
Newcastle disease (ND), caused by the Newcastle disease virus (NDV), is a highly virulent infectious disease of poultry. Virulent NDV can cause severe autophagy and inflammation in host cells. While studies have shown a mutual regulatory relationship between autophagy and inflammation, this relationship in NDV infection remains unclear. This study confirmed that NDV infection could trigger autophagy in DF-1 cells to promote cytopathic and viral replication. NDV-induced autophagy was positively correlated with the mRNA levels of inflammatory cytokines such as IL-1β, IL-8, IL-18, CCL-5, and TNF-α, suggesting that NDV-induced autophagy promotes the expression of inflammatory cytokines. Further investigation demonstrated that NLRP3 protein expression, Caspase-1 activity, and p38 phosphorylation level positively correlated with autophagy, suggesting that NDV-induced autophagy could promote the expression of inflammatory cytokines through NLRP3/Caspase-1 inflammasomes and p38/MAPK pathway. In addition, NDV infection also triggered mitochondrial damage and mitophagy in DF-1 cells, but did not result in a large leakage of reactive oxygen species (ROS) and mitochondrial DNA (mtDNA), indicating that mitochondrial damage and mitophagy do not contribute to the inflammation response during NDV infection.

Abstract
Newcastle disease (ND) is an acute, febrile, and highly contagious disease caused by the Newcastle disease virus (NDV), an important pathogen harmful to domestic poultry. Virulent NDV strain infection induces IL-1β expression and along with strong inflammatory response, ultimately results in death. Inhibition or overexpression of S1PR1, an important target for inflammatory disease treatment, regulates IL-1β expression, suggesting that S1PR1 may alter the degree of the inflammatory response induced by NDV infection by regulating pro-inflammatory cytokine expression. However, the molecular mechanism by which S1PR1 regulates IL-1β expression remains unclear. Here, we explore the expression and tissue distribution of S1PR1 after NDV infection and found that S1PR1 expression increased in the lungs, bursa of Fabricius, and DF-1. IL-1β expression induced by NDV was increased following treatment of cells with the S1PR1-specific agonist, SEW2871. In contrast, IL-1β expression induced by NDV was decreased after cells were treated with the S1PR1 inhibitor W146, suggesting that S1PR1 promotes NDV-induced IL-1β expression. Further investigation demonstrated that NDV induced IL-1β expression through p38, JNK/MAPK, and NLRP3/caspase-1 signaling molecules and S1PR1 affected the expression of IL-1β by activating the NLRP3/caspase-1 inflammasome but had no significant effect on p38 and JNK/MAPK. Our study shows that NDV infection promotes S1PR1 expression and induces IL-1β expression through p38, JNK/MAPK, and NLRP3/caspase-1 inflammasomes and that S1PR1 regulates IL-1β expression mainly through the NLRP3/caspase-1 inflammasome.

Abstract
Newcastle disease virus genotype VII (NDV-GVII) is a highly contagious pathogen responsible for pandemics that have caused devastating economic losses in the poultry industry. Several features in the transcription of NDV mRNA, including differentially expressed genes across the viral genome, are shared with that for other single, non-segmented, negative-strand viruses. Previous studies measuring viral gene expression using northern blotting indicated that the NDV transcription produced non-equimolar levels of viral mRNAs. However, deep high-throughput sequencing of virus-infected tissues can provide a better insight into the patterns of viral transcription. In this report, the transcription pattern of virulent NDV-GVII was analysed using RNA-seq and qRT-PCR. This study revealed the transcriptional profiling of these highly pathogenic NDV-GVII genes: NP:P:M:F:HN:L, in which there was a slight attenuation at the NP:P and HN:L gene boundaries. Our result also provides a fully comprehensive qPCR protocol for measuring viral transcript abundance that may be more convenient for laboratories where accessing RNA-seq is not feasible.

Abstract
The direct oncolytic effect of Newcastle disease virus (NDV) depends on the following two aspects: the susceptibility of cancer cells to virus infection and the ability of virus itself to lyse cancer cells. First, we investigate the susceptibility of cancer cells to NDV infection, HepG2, MDA-MB-231, and SH-SY5Y cells were susceptible, A549, MCF7, and LoVo cells were less susceptible. To investigate the molecular mechanism responsible for cancer cell susceptibility, transcriptome sequencing was carried out. We found that the levels of alpha-sialic acid acyltransferase were upregulated in MDA-MB-231 cells compared with MCF7 cells, and the interferon was downregulated. Second, to optimize the oncolytic capacity of the wild-type rClone30, a series of chimeric viruses rClone30-Anh(HN), rClone30-Anh(F), and rClone30-Anh(HN-F) were constructed by exchanging the HN gene, F gene or both of non-lytic rClone30 strain with lytic strain Anhinga. rClone30-Anh(F) and rClone30-Anh(HN-F) enhanced the oncolytic effect of the rClone30, and this enhancement is more obvious in the susceptible cells. The oncolytic mechanism of rClone30-Anh(F) was analyzed by transcriptome analyses, in comparison with rClone30, rClone30-Anh(F) upregulated the expression of ATG5, Beclin 1, and MAP1LC3B, thus activating autophagy and promoting the production of syncytia. In conclusion, our study provides a strategy to enhance the oncolytic effect of rClone30.

Abstract
Upregulation of matrix metalloproteinase (MMP)-14, a major driven force of extracellular-matrix (ECM) remodelling and cell migration, correlates with ECM breakdown and pathologic manifestation of genotype VII Newcastle disease virus (NDV) in chickens. However, the functional relevance between MMP-14 and pathogenesis of genotype VII NDV remains to be investigated. In this study, expression, biofunction and regulation of MMP-14 induced by genotype VII NDV were analysed in chicken peripheral blood mononuclear cells (PBMCs). The results showed that JS5/05 significantly increased expression and membrane accumulation of MMP-14 in PBMCs, correlating to enhanced collagen degradation and cell migration. Specific MMP-14 inhibition significantly impaired collagen degradation and migration of JS5/05-infected cells, suggesting dependence of these features on MMP-14. In addition, MMP-14 upregulation correlated with activation of the extracellular signal-regulated kinase (ERK) pathway upon JS5/05 infection, and blockage of the ERK signalling significantly suppressed MMP-14-mediated collagen degradation and migration of JS5/05-infected cells. Using a panel of chimeric NDVs derived from gene exchange between genotype VII and IV NDV, the fusion and haemagglutinin-neuraminidase genes were identified as the major viral determinants for MMP-14 expression and activity. In conclusion, MMP-14 was defined as a critical regulator of collagen degradation and cell migration of chicken PBMCs infected with genotype VII NDV, which may contribute to pathology of the virus. Our findings add novel information to the body of knowledge regarding virus-host biology and NDV pathogenesis.

Abstract
As the causative agent of Newcastle disease (ND), Newcastle disease virus (NDV) has seriously restricted the development of the poultry industry. Previous research has shown that miRNAs, members of the small noncoding RNA family, are implicated in the regulation NDV replication through extensive interactions with host mRNAs, but whether miRNAs affect NDV replication by directly binding to the NDV antigenome remains unclear. In this study, potential Gallus gallus miRNAs targeting the antigenome of NDV were bioinformatically predicted using the online software RegRNA 2.0, and gga-miR-1603 and gga-miR-1794 were identified as targeting the viral L gene directly through dual-luciferase reporter assays. Sequence alignment analysis demonstrated that multiple genotypes of NDVs harbored highly conserved binding sites for gga-miR-1603 and gga-miR-1794 in the viral antigenome located at 8611–8634 nt and 14,490–14,514 nt, respectively. Meanwhile, we found that gga-miR-1603 and gga-miR-1794 negatively regulated the expression of viral L gene at both the RNA and protein levels, as well as viral replication in vitro. Furthermore, NDV infection had no effect on endogenous gga-miR-1603 and gga-miR-1794 expression in various avian cell lines. Overall, our present study demonstrated that gga-miR-1603 and gga-miR-1794 directly bind to the viral L gene to facilitate ts degradation and inhibit the replication of multiple genotypes of NDVs in vitro. These findings will provide us with important clues for antiviral therapy against NDV infection.

Comparative biology of two genetically closely related Newcastle disease virus strains with strongly contrasting pathogenicity. Vet Microbiol 2020; 253:108977. [PMID: 33421684 DOI: 10.1016/j.vetmic.2020.108977] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Accepted: 12/26/2020] [Indexed: 10/22/2022]
Abstract
A lentogenic strain of Newcastle disease virus (NDV) with an intracerebral pathogenicity index (ICPI) of 0.36 was derived by the passage of a mesogenic NDV isolate with an original ICPI of 1.04. Animal experiments showed that the original strain caused much severer clinical signs and mortality than the derived strain in chickens. To elucidate the molecular reason for this virulence change, the complete viral genomes of the original and derived strains were sequenced. Molecular analysis showed that both viruses contained the same fusion (F) protein with a cleavage site (Fcs) motif that is usually associated with velogenic viruses. Molecular comparison revealed five amino acid (aa) differences in nucleoprotein (NP) (aa 426), hemagglutinin-neuraminidase (HN) (aas 215 and 430), and large protein (L) (aas 1694 and 1767), accompanied by the changes of relevant biological activities in membrane fusion and replication. Thus, we believe that the virulence changes may induced by these mutations. Our findings make a foundation for more in-depth investigations of the molecular mechanism underlying virulence.

Abstract
Newcastle disease virus (NDV) infection causes severe inflammation and is a highly contagious disease in poultry. Virulent NDV strains (GM) induce large quantities of interleukin-1β (IL-1β), which is the central mediator of the inflammatory reaction. Excessive expression of IL-1β exacerbates inflammatory damage. Therefore, exploring the mechanisms underlying NDV-induced IL-1β expression can aid in further understanding the pathogenesis of Newcastle disease. Here, we showed that anti-IL-1β neutralizing antibody treatment decreased body temperature and mortality following infection with virulent NDV. We further explored the primary molecules involved in NDV-induced IL-1β expression from the perspective of both the host and virus. This study showed that overexpression of NLRP3 resulted in increased IL-1β expression, whereas inhibition of NLRP3 or caspase-1 caused a significant reduction in IL-1β expression, indicating that the NLRP3/caspase-1 axis is involved in NDV-induced IL-1β expression. Moreover, ultraviolet-inactivated GM (chicken/Guangdong/GM/2014) NDV failed to induce the expression of IL-1β. We then collected virus from GM-infected cell culture supernatant using ultracentrifugation, extracted the viral RNA, and stimulated the cells further with GM RNA. The results revealed that RNA alone was capable of inducing IL-1β expression. Moreover, NLRP3/caspase-1 was involved in GM RNA-induced IL-1β expression. Thus, our study elucidated the critical role of IL-1β in the pathogenesis of Newcastle disease while also demonstrating that inhibition of IL-1β via anti-IL-1β neutralizing antibodies decreased the damage associated with NDV infection; furthermore, GM RNA induced IL-1β expression via NLRP3/caspase-1.

Genotype-matched Newcastle disease virus vaccine confers improved protection against genotype XII challenge: The importance of cytoplasmic tails in viral replication and vaccine design. PLoS One 2019; 14:e0209539.

Abstract
Although typical Newcastle disease virus (NDV) vaccines can prevent mortality, they are not effective in preventing viral shedding. To overcome this, genotype-matched vaccines have been proposed. To date, this approach has never been tested against genotype XII strains. In this study, we generated and assessed the protection against genotype XII challenge of two chimeric NDV vaccine strains (rLS1-XII-1 and rLS1-XII-2). The rLS1-XII-1 virus has the complete fusion protein (F) and the hemagglutinin-neuraminidase (HN) open reading frames replaced with those from genotype XII strain NDV/peacock/Peru/2011 (PP2011) in a recombinant LaSota (rLS1) backbone. In rLS1-XII-2 virus, cytoplasmic tails of F and HN proteins were restored to those of rLS1. In vitro evaluation showed that rLS1-XII-2 and the parental rLS1 strains replicate at higher efficiencies than rLS1-XII-1. In the first vaccine/challenge experiment, SPF chickens vaccinated with rLS1-XII-1 virus showed only 71.3% protection, whereas, rLS1 and rLS1-XII-2 vaccinated chickens were fully protected. In a second experiment, both rLS1-XII-2 and the commercial vaccine strain LaSota induced 100% protection. However, rLS1-XII-2 virus significantly reduced viral shedding, both in the number of shedding birds and in quantity of shed virus. In conclusion, we have developed a vaccine candidate capable of fully protecting chickens against genotype XII challenges. Furthermore, we have shown the importance of cytoplasmic tails in virus replication and vaccine competence.

Abstract
In this study, we investigated which structural proteins of pigeon paramyxovirus type 1 (PPMV-1) are responsible for its low pathogenicity in chickens. The results revealed that the pathogenicity of the virus is determined by multiple genes. The NP protein and F protein were found to have the strongest individual effect on virulence, and this effect further enhanced when the two proteins were expressed in combination. Our study highlights the influence of the NP and F proteins on the pathogenicity of PPMV-1 in chickens.

Abstract
The nucleoprotein (NP) of pigeon paramyxovirus type 1 (PPMV-1) and other paramyxoviruses plays an important role in virus proliferation. A previous study found that NP is associated with the low pathogenicity of PPMV-1 strains in chickens. Here, we investigated which domain of NP is responsible for regulating the pathogenicity of PPMV-1. We found that the Ntail sequences were more diverse for different viral genotypes compared to Ncore sequences. The chimeric rBJ-SG10Ntail strain caused more severe clinical symptoms than the parental rBJ strain, increased the viral copy number in sampled tissues and induced higher IFN-γ gene expression. This demonstrated that the Ntail sequence plays a role in regulating viral virulence. These findings increase our understanding of the Ntail of NP protein and the virulence factors associated with PPMV-1.

Abstract
BACKGROUND Virulent Newcastle disease virus (vNDV) causes great economic losses to the poultry industry throughout the world. Despite the endemicity of Newcastle disease (ND) and occurrence of recurrent outbreaks, the nature and genetic features of circulating NDV strains in Iran are largely unknown. Aims: This study was conducted to characterize 13 NDV isolates obtained from different outbreaks in various regions of Iran during 1999-2000 by sequencing and phylogenetic analysis of complete coding sequences of haemagglutinin-neuraminidase (HN) gene. METHODS All isolates were analyzed based on the previously determined in vivo pathogenicity indices and amino acid (aa) sequences of fusion (F) protein cleavage site (FPCS). RESULTS Phylogenetic analysis based on the HN gene coding region revealed a very close relationship of these viruses with the recently defined genotype XIII, and more specifically, subgenotype XIIIa viruses. Analysis of HN gene nucleotide (nt) sequences revealed that all studied isolates encode for a protein length of 571 aa and there is no C-terminal extension on HN aa sequences. Sequence analysis revealed multiple aa residue substitutions at antigenic sites or neutralizing epitopes on the HN glycoprotein of studied viruses compared with commonly used vaccinal strains. CONCLUSION In this study, molecular characterization of vNDV isolates, obtained from commercial poultry farms in Iran, were conducted through complete sequencing and analysis of HN gene. Isolation and molecular characterization of further NDV isolates from other parts of Iran and from neighboring countries in the region will be helpful to identify the nature and origin of indigenous viruses.

Abstract
The virulence of Newcastle disease virus varies greatly and is determined by multiple genetic factors. In this study, we systematically evaluated the roles of the polymerase-associated (NP, P and L) protein genes in genotype VII NDV virulence after confirming the envelope-associated (F and HN) proteins contributed greatly to NDV virulence. The results revealed that the polymerase-associated protein genes individually had certain effect on virulence, while transfer of these three genes in combination significantly affected the chimeric virus virulence, especially when the L gene was involved. These results indicated that the L protein was a major contributor to NDV virulence when combined with the homologous NP and P proteins. We also investigated viral RNA synthesis using NDV minigenome systems to assess the interaction between the NP, P, and L proteins, which showed that the activity of the polymerase-associated proteins were directly related to viral RNA transcription and replication.
