[3H]palmitic acid was metabolically incorporated into the viral fusion protein (F) of Edmonston or freshly isolated measles virus (MV) during infection of human lymphoid or Vero cells. The uncleaved precursor F0 and the F1 subunit from infected cells and extracellular virus were both labeled, indicating that palmitoylation can take place prior to F0 cleavage and that palmitoylated F protein was...

Background and Aims: Newcastle disease (ND), caused by the virulent Newcastle disease virus (NDV), is one of the most important viral diseases in birds. In recent years recombination occurring throughout the NDVs genome isolated in China and Indonesia has been reported. This study was focused to investigate the recombination events in the F gene of the Iranian NDVs to generate useful data that ...

An insulin-responsive element (IRE) in the rat angiotensinogen (ANG) gene promoter that binds to two nuclear proteins with apparent molecular weights of 48 and 70 kD was identified previously from rat immortalized renal proximal tubular cells (IRPTC). The present studies aimed to identify and clone the 48-kD nuclear protein and to define its action on ANG gene expression. Nuclear proteins were ...

background: expression of epstein-barr virus latent member protein-1 (ebv lmp-1) and loss of p16 protein expression are documented in lymphoma, indicating a relationship between them, but this relationship is not clear and sometimes contradictory. thus, this study was conducted to examine the relationship between the loss of p16 and ebv lmp-1 expression in jordanian patients diagnosed with lymp...

objectives: the purpose of this study was to evaluate the effect of cuminum cyminum (c. cyminum) essential oil on the growth and fum1 gene expression of fumonisin-producing fusarium verticillioides (f. verticillioides) strains isolated from maize. materials and methods: all fungal strains were cultured on potato dextrose agar (pda) slopes at 30°c for 7 days. the antifungal activity was evaluate...

This study investigated the possibility to improve use of plant based feed in common carp (Cyprinus carpio), via feeding diet from early life stage. Fry, obtained larvae produced by broodstock fed with either two diets viz. fish (F diet) or (P diet), were stocked into six earthen ponds triplicate. Fry F- and P- group also isoproteic (37% crude protein) isolipidic (6.5% lipid) respectively, for ...

Avian pneumovirus (APV) was first isolated from turkeys in the west-central US following emergence of turkey rhinotracheitis (TRT) during 1996. Subsequently, several APV isolates were obtained from the north-central US. Matrix (M) and fusion (F) protein genes of these isolates were examined for sequence heterogeneity and compared with European APV subtypes A and B. Among US isolates the M gene ...

background: the hbv-x (hbx) protein is believed to contribute to the development of hcc. however, the molecular mechanisms involved in hbx-mediated hepatocarcinogenesis remain obscure. in this study, the effect of hepatitis b virus x gene and its protein product hbxag on expression of p53 gene in hep g2 cell line was investigated. methods: viral dna extracted from hbv-positive serum and hbx gen...

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 isolat...
