Abstract
Bovine viral diarrhea virus (BVDV) causes a severe threat to the cattle industry due to ineffective control measures. Gypenoside is the primary component of Gynostemma pentaphyllum, which has potential medicinal value and has been widely applied as a food additive and herbal supplement. However, little is known about the antiviral effects of gypenoside. The present study aimed to explore the antiviral activities of gypenoside against BVDV infection. The inhibitory activity of gypenoside against BVDV was assessed by using virus titration and performing Western blotting, quantitative reverse transcription PCR (RT-qPCR), and immunofluorescence assays in MDBK cells. We found that gypenoside exhibited high anti-BVDV activity by interfering with the viral attachment to and internalization in cells. The study showed that BVDV infection inhibits apoptosis of infected cells from escaping the innate defense of host cells. Our data further demonstrated that gypenoside inhibited BVDV infection by electively activating the apoptosis of BVDV-infected cells for execution, as evidenced by the regulation of the expression of the apoptosis-related protein, promotion of caspase-3 activation, and display of positive TUNEL staining; no toxicity was observed in non-infected cells. Collectively, the data identified that gypenoside exerts an anti-BVDV-infection role by inhibiting viral attachment and internalization and selectively purging virally infected cells. Therefore, our study will contribute to the development of a novel prophylactic and therapeutic strategy against BVDV infection.

Analysis of microRNAs Expression Profiles in Madin-Darby Bovine Kidney Cells Infected With Caprine Parainfluenza Virus Type 3. Front Cell Infect Microbiol 2018; 8:93. [PMID: 29651410 PMCID: PMC5885596 DOI: 10.3389/fcimb.2018.00093] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2017] [Accepted: 03/12/2018] [Indexed: 12/12/2022] Open
Abstract
Caprine parainfluenza virus type 3 (CPIV3) is a newly emerging pathogenic respiratory agent infecting both young and adult goats, and it was identified in eastern China in 2013. Cellular microRNAs (miRNAs) have been reported to be important modulators of the intricate virus-host interactions. In order to elucidate the role of miRNAs in madin-darby bovine kidney (MDBK) cells during CPIV3 infection. In this study, we performed high-throughput sequencing technology to analyze small RNA libraries in CPIV3-infected and mock-infected MDBK cells. The results showed that a total of 249 known and 152 novel candidate miRNAs were differentially expressed in MDBK cells after CPIV3 infection, and 22,981 and 22,572 target genes were predicted, respectively. In addition, RT-qPCR assay was used to further confirm the expression patterns of 13 of these differentially expressed miRNAs and their mRNA targets. Functional annotation analysis showed these up- and downregulated target genes were mainly involved in MAPK signaling pathway, Jak-STAT signaling pathway, Toll-like receptor signaling pathway, p53 signaling pathway, focal adhesion, NF-kappa B signaling pathway, and apoptosis, et al. To our knowledge, this is the first report of the comparative expression of miRNAs in MDBK cells after CPIV3 infection. Our finding provides information concerning miRNAs expression profile in response to CPIV3 infection, and offers clues for identifying potential candidates for antiviral therapies against CPIV3.

[PMID: 36494951 DOI: 10.18821/0507-4088-2017-62-5-204-210] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Indexed: 12/13/2022]
Abstract
Bovine viral diarrhea virus (BVDV) belongs to the genus Pestivirus, family Flaviviridae. It causes various clinical forms of infection leading to significant economic losses in beef and dairy industry worldwide. Furthermore, the virus is a contaminant of biological preparations (bovine fetal serum, continuous cell cultures, vaccines for human and veterinary medicine, interferons, trypsin, biotechnological preparations, embryos, stem cells, etc.). It is used as a test object when developing methods of decontamination. In some countries, a tool for monitoring the infection caused by the virus is vaccination based on the use of live and inactivated vaccines with varying efficiency. The antiviral compounds are a potential means of control in case of insufficient efficacy of vaccines. Their advantage for BVDV control is the ability to provide immediate protection for animals at risk in the case of an outbreak of the disease. This review summarizes the current state of knowledge about antiviral compounds against BVDV. It was noted that due to the use of advanced biomedical technologies there is a tendency to search for drugs that might be effective for antiviral therapy of BVDV, as indicated by numerous studies of new compounds and the antiviral efficacy of known drugs used in medical practice. In addition to the well-known antiviral targets for the virus, such as the RdRp, IMPDH, NS3, new targets were discovered, such as protein p7. Its mechanism of action remains to be explored. It can be concluded that there is a great potential for BVDV control through the use of antiviral drugs which has not yet implemented. The biggest obstacle for commercial implementation of identified compounds is the lack of demonstration of their efficacy in vivo. Further studies should be performed to develop a method for administering effective drugs to groups of animals.
