Abstract
The prevention of viral transmission is an important step to address the spread of viral infections. Using the enveloped vesicular stomatitis virus (VSV) as a model, this study explored the antiviral functions of the specifically designed and prepared carbon dots (CDots). The CDots were prepared using small carbon nanoparticles with surface functionalization-passivation by oligomeric polyethylenimine (PEI). The results indicated that the PEI-CDots were readily activated by visible light to effectively and efficiently inactivate VSVs under various combinations of experimental conditions (viral titer, dot concentration, and treatment time). The photodynamically induced viral structural protein degradation and genomic RNA degradation were observed, suggesting the mechanistic origins, leading to the inactivation of virus. The results suggested CDots as a class of promising broad-spectrum antiviral agents for disinfection of viruses.

The host cellular protein Ndufaf4 interacts with the vesicular stomatitis virus M protein and affects viral propagation. Virus Genes 2021; 57:250-257. [PMID: 33635491 DOI: 10.1007/s11262-021-01833-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Accepted: 02/10/2021] [Indexed: 10/22/2022]
Abstract
Vesicular stomatitis virus (VSV) is an archetypal member of Mononegavirales which causes important diseases in cattle, horses and pigs. The matrix protein (M) of VSV plays critical roles in the replication, assembly/budding and pathogenesis of VSV. To further investigate the role of M during viral growth, we used a two-hybrid system to screen for host factors that interact with the M protein. Here, NADH: ubiquinone oxidoreductase complex assembly factor 4 (Ndufaf4) was identified as an M-binding partner, and this interaction was confirmed by yeast cotransformation and GST pulldown assays. The globular domain of M was mapped and shown to be critical for the M-Ndufaf4 interaction. Two double mutations (E156A/H157A, D180A/E181A) in M impaired the M-Ndufaf4 interaction. Overexpression of Ndufaf4 inhibited VSV propagation, and knockdown of Ndufaf4 by short hairpin RNA (shRNA) markedly promoted VSV replication. Finally, we also demonstrate that the anti-VSV effect of Ndufaf4 is independent of activation of the type I IFN response. These results indicated that Ndufaf4 might exploit other mechanisms to affect VSV replication. In summary, we identify Ndufaf4 as a potential target for the inhibition of VSV propagation. These results provided further insight into the study of VSV pathogenesis.

FISH & SHELLFISH IMMUNOLOGY 2020; 98:77-86.

Abstract
The eukaryotic proteasome is a large multi-subunit complex that plays an important role in a wide range of fundamental cellular functions by degrading un-needed or damaged proteins, which also can be inverted or manipulated by viruses to favor viral infection. In this study, we demonstrated that proteasome subunit beta-type 7 (PSMB7), a proteasome-constitutive protein that is important for proteasome assembly, interacts with grass carp reovirus (GCRV) capsid proteins. Yeast 2-hybrid assay indicates that capsid protein VP38 of genotype Ⅲ GCRV could bind PSMB7, and this mutual interaction was further confirmed by pull-down, co-immunoprecipitation and subcellular co-localization assays. Furthermore, VP38 homologous proteins, VP7 from genotype I and VP35 from genotype II GCRV, can also interact with host PSMB7 in similar protein-protein interaction assays. Finally, PSMB7 expression level remains stable during GCRV infection, while, psmb7 gene transcription was repressed upon GCRV challenge; interaction with PSMB7 doesn't result in protein degradation of either VP7 or VP38 during viral infection. Thus, the interaction between host PSMB7 and viral capsid protein might suggest that interfering with PSMB7-mediated proteasome assembly should be involved in efficient aquareovirus infection.

Abstract
Colorectal cancer (CRC) is the third most common cancer in both men and women. Oncolytic viral-based therapy methods seem to be promising for CRC treatment. Vesicular stomatitis virus (VSV) is considered as a potent candidate in viral therapy for several tumors. VSV particles with mutated matrix (M) protein are capable of initiating cell death cascades while not being harmful to the immune system. In the current study, the effects of the VSV M-protein was investigated on the apoptosis of the colorectal cancer SW480 cell. Wild-type, M51R, and ΔM51 mutants VSV M-protein genes were cloned into the PCDNA3.1 vector and transfected into the SW480 cells. The results of the MTT assay, Western blotting, and Caspase 3, 8, and 9 measurement, illustrated that both wild and M51R mutant M-proteins can destroy the SW480 colorectal cancer cells. DAPI/TUNEL double-staining reconfirmed the apoptotic effects of the M-protein expression. The ΔM51 mutant M-protein is effective likewise M51R, somehow it can be considered as a safer substitution.

Abstract
VSV M protein interacts with the i subunit of eIF3. The region of M that interacts with eIF3i is located within the 122- to -181 amino acids. M–eIF3i interaction affects VSV growth.
The matrix protein of vesicular stomatitis virus (VSV) performs multiple functions during viral genome replication and virion production and is involved in modulating multiple host signaling pathways that favor virus replication. To perform numerous functions within infected cells, the M protein needs to recruit cellular partners. To better understand the role of M during VSV replication, we looked for interacting partners by using the two-hybrid system. The eukaryotic translation initiation factor 3, subunit i (eIF3i) was identified to be an M-binding partner, and this interaction was validated by GST pull-down and laser confocal assays. Through a mutagenesis analysis, we found that some mutants of M between amino acids 122 and 181 impaired but did not completely abolish the M–eIF3i interaction. Furthermore, the knockdown of eIF3i by RNA interference decreased viral replication and transcription in the early stages but led to increase in later stages. VSV transcription was increased at 4 h post-infection but was not changed at 8 and 12 h post-infection after the over-expression of eIF3i. Finally, we also demonstrated that VSV could inhibit the activity of Akt1 and that the knockdown of eIF3i inhibited the expression of the ISGs regulated by phospho-Akt1. These results indicated that eIF3i may affect VSV growth by regulating the host antiviral response in HeLa cells.

Abstract
Tumor progression and metastasis are dependent on the intrinsic properties of tumor cells and the influence of microenvironment including the immune system. It would be important to identify target drug that can inhibit cancer cell and activate immune cells. Proteasome β subunits (PSMB) family, one component of the ubiquitin-proteasome system, has been demonstrated to play an important role in tumor cells and immune cells. Therefore, we used a bioinformatics approach to examine the potential role of PSMB family. Analysis of breast TCGA and METABRIC database revealed that high expression of PSMB5 was observed in breast cancer tissue and that high expression of PSMB5 predicted worse survival. In addition, high expression of PSMB5 was observed in M2 macrophages. Based on our bioinformatics analysis, we hypothesized that PSMB5 contained immunosuppressive and oncogenic characteristics. To study the effects of PSMB5 on the cancer cell and macrophage in vitro, we silenced PSMB5 expression with shRNA in THP-1 monocytes and MDA-MB-231 cells respectively. Knockdown of PSMB5 promoted human THP-1 monocyte differentiation into M1 macrophage. On the other hand, knockdown PSMB5 gene expression inhibited MDA-MB-231 cell growth and migration by colony formation assay and boyden chamber. Collectively, our data demonstrated that delivery of PSMB5 shRNA suppressed cell growth and activated defensive M1 macrophages in vitro. Furthermore, lentiviral delivery of PSMB5 shRNA significantly decreased tumor growth in a subcutaneous mouse model. In conclusion, our bioinformatics study and functional experiments revealed that PSMB5 served as novel cancer therapeutic targets. These results also demonstrated a novel translational approach to improve cancer immunotherapy.

Abstract
Virus resistance to antiviral therapies is an increasing concern that makes the development of broad-spectrum antiviral drugs urgent. Targeting of the viral envelope, a component shared by a large number of viruses, emerges as a promising strategy to overcome this problem. Natural and synthetic porphyrins are good candidates for antiviral development due to their relative hydrophobicity and pro-oxidant character. In the present work, we characterized the antiviral activities of protoprophyrin IX (PPIX), Zn-protoporphyrin IX (ZnPPIX), and mesoporphyrin IX (MPIX) against vesicular stomatitis virus (VSV) and evaluated the mechanisms involved in this activity. Treatment of VSV with PPIX, ZnPPIX, and MPIX promoted dose-dependent virus inactivation, which was potentiated by porphyrin photoactivation. All three porphyrins inserted into lipid vesicles and disturbed the viral membrane organization. In addition, the porphyrins also affected viral proteins, inducing VSV glycoprotein cross-linking, which was enhanced by porphyrin photoactivation. Virus incubation with sodium azide and α-tocopherol partially protected VSV from inactivation by porphyrins, suggesting that singlet oxygen (1O2) was the main reactive oxygen species produced by photoactivation of these molecules. Furthermore, 1O2 was detected by 9,10-dimethylanthracene oxidation in photoactivated porphyrin samples, reinforcing this hypothesis. These results reveal the potential therapeutic application of PPIX, ZnPPIX, and MPIX as good models for broad antiviral drug design.
