As causative agents of duck viral hepatitis, duck hepatitis A virus type 1 (DHAV-1) and type 3 (DHAV-3) causes significant economic losses in the duck industry. However, a licensed commercial vaccine that simultaneously controls both pathogens is currently unavailable. Here, we generated duck enteritis virus recombinants (rC-KCE-2VP1) containing both VP1 from DHAV-1 (VP1/DHAV-1) and VP1 from DH...
Poliovirus type 1 cDNA sequences coding for viral capsid polypeptide VP1 were inserted into the beta-lactamase sequence of Escherichia coli plasmid pBR322. Resulting recombinant plasmid pSW119 expressed in Escherichia coli a VP1-beta-lactamase fusion protein that reacted with antibodies raised against poliovirus capsid polypeptide VP1 and with a monoclonal poliovirus type 1 neutralizing antibod...
Coxsackievirus B3 (CVB3) belongs to the genus Enterovirus of family Picornaviridae and can cause acute acinar pancreatitis in adults. However, molecular mechanisms pathogenesis underlying CVB3-induced have remained unclear. In this study, we discovered that CVB3 capsid protein VP1 inhibited pancreatic cell proliferation exerted strong cytopathic effects on HPAC cells. Through yeast two-hybrid, ...
Small deletions were introduced into DNA plasmids bearing cDNA copies of Mahoney type 1 poliovirus RNA. The procedure used was similar to that of P. Hearing and T. Shenk (J. Mol. Biol. 167:809-822, 1983), with modifications designed to introduce only one lesion randomly into each DNA molecule. Methods to map small deletions in either large DNA or RNA molecules were employed. Two poliovirus muta...
How alphaherpesvirus capsids acquire tegument proteins remains a key question in viral assembly. Using pseudorabies virus (PRV), we have previously shown that the 62 carboxy-terminal amino acids of the VP1/2 large tegument protein are essential for viral propagation and when transiently expressed as a fusion to green fluorescent protein relocalize to nuclear capsid assemblons following viral in...
The viviparous-1 (vp1) gene in maize controls multiple developmental responses associated with the maturation phase of seed formation. Most notably, mutant embryos have reduced sensitivity to the hormone abscisic acid, resulting in precocious germination, and blocked anthocyanin synthesis in aleurone and embryo tissues. The Vp1 locus was cloned by transposon tagging, using the Robertson's Mutat...
JC virus (JCV)-specific cytotoxic T lymphocytes (CTL) in peripheral blood are associated with a favorable outcome in patients with progressive multifocal leukoencephalopathy (PML). However, the frequency of these cells in the peripheral blood mononuclear cells (PBMC) of PML patients is unknown. To develop a highly sensitive assay for detecting the cellular immune response against this virus, we...
Enteroviruses (EVs) are common seasonal viruses that are associated with a variety of diseases. High-quality monoclonal antibodies (MAbs) are needed to improve the accuracy of EV diagnosis in clinical laboratories. In the present study, the full-length VP1 genes of poliovirus 1 (Polio 1) and coxsackievirus B3 (Cox B3) were cloned, and the encoded proteins were expressed and used as antigens in ...
cis,trans-Abscisic acid (ABA) plays an important role in plant growth and development, regulation of seed maturation, germination, and adaptation to environmental stresses. Knowledge of ABA mechanisms of action and the interactions of components required for ABA signal transduction is far from complete. Using transient gene expression in rice protoplasts, we observed additive and inhibitory eff...
foot and mouth disease (fmd) is highly contagious disease among cloven-hoofed animals. fmd virus has structural and non-structural proteins. vp1 is the most immunogenic structural peptides of fmd virus, applied for major vaccine studies. objective: construction of pet28-vp1 cassette for fmd virus type o/irn/2010 and expression vp1 peptide as the most immunogenic antigen was the aim of this stud...
