Tumorcidal Effect of Recombinant Newcastle Disease Virus

چکیده
We have generated GFP expressing recombinant Newcastle Disease Virus (rNDV-GFP) based on a live vaccine strain which contains a less pathogenic cleavage site of F protein leading to restricted viral growth in vivo. We evaluated the rNDV have an effect of oncolytic activity to B16 melanoma cell. The rNDV-GFP infected efficiency to B16 cells and induced cell death. Apoptosis-related genes, Bax and Caspase 3, were elevated in the infected cells. In order to evaluate the tumorcidal effect of rNDV on canine tumor cells, two canine tumors such as highly metastasizing canine osteosarcoma (HMPOS) and transitional cell carcinoma (TCC) were infected with rNDV. The rNDV induced cell death to canine tumor cells within 48 hours post infection. These results suggest that rNDV-GFP have a tumorcidal activity to B16 mouse melanoma and canine tumors in vitro.

Construction of Recombinant Bacmid DNA Encoding Newcastle Disease Virus (NDV) Fusion Protein Gene
Background and Aims: Newcastle disease virus (NDV) is one of the major pathogen in poultry. Vaccination is intended to control the disease as an effective solution nevertheless this virus is a growing threat to the poultry industry. F gene open reading frame (ORF) from NDV is 1650 bp, encoding a protein of 553 amino acids that can induce protective immunity alone. The F glycoprotein on the surf...

Background: Newcastle disease virus (NDV) is a dangerous viral disease, infecting a broad range of birds, and has a fatal effect on the poultry industries. The attachment and consequently fusion of the virus to the host cell membrane is directed by the two superficial glycoproteins, the hemagglutinin-neuraminidase (HN) and the fusion (F) which is considered as the important tar...

The aim of this experiment was to study the effect of in ovoinjection of royal jelly (RJ) on growth performance and immune response in broiler chickens challenged with Newcastle disease virus. A total of 200 hatching eggs were divided into four groups of 50 eggs each one using a completely randomized design. The eggs were injected with sterilized sodium bicarbonate buffer (pH=10.4) or RJ (88%) ...
