Infectious bursal disease virus (IBDV) is the causative agent of Gumboro disease, an infectious disease of global economic importance in poultry. Structural protein VP2 of IBDV is the most frequently studied protein due to its significant roles in virus attachment, protective immunity, and serotype specificity. The objective of the present study was to improve the expression of hypervariable re...

28 The terminal non-coding region (NCR) sequences of the eight gene segments of the influenza 29 A/Brevig Mission/1/1918 (H1N1) virus were determined by rapid amplification of cDNA ends 30 (RACE). Chimeric viruses encoding the open reading frames of the 1918 virus but flanked by 31 either the wild-type 1918 NCR sequences, or the NCR sequences of two other H1N1 virus 32 strains, A/WSN/1933 and A...

Adaptation in the overall codon usage pattern of West Nile virus (WNV) to that of two hosts was estimated based on the synonymous codon usage value (RSCU). Synonymous codon usage biases for the beginning coding sequence of this virus were also analyzed by calculating the usage fluctuation for each synonymous codon along the target region (the first 270 codon sites of the whole coding sequence o...

We have sequenced the complete coding region of a chikungunya virus isolate (R91064) used in the formulation of CBER/FDA RNA reference reagents for nucleic acid technology testing.

background pe5 is a member of the pe protein family whose precise function is yet to be understood. there are about 100 members of the pe family proteins in mycobacterium tuberculosis. these glycine- and alanine-rich proteins consist of proline-glutamate motifs at their n-termini and may be implicated in pathogenesis of the bacilli. objectives we aimed to clone and over-express the rv0285 codin...

Previous results have indicated that Rous sarcoma virus env gene expression is specifically inhibited by antisense RNA (L.-J. Chang and C. M. Stoltzfus, Mol. Cell. Biol. 5:2341-2348, 1985). In this study, we compare the extents of inhibition by antisense RNA derived from different parts of the Rous sarcoma virus genome, and we show that antisense constructs containing the 3'-end noncoding regio...

We determined the nucleotide sequence of the acute transforming avian retrovirus MH2 from an HgiAI site within the coding region of its oncogene, v-myc, to the KpnI site within the long terminal repeat. Comparison with published sequences from other retroviruses allowed us to identify all sequence elements in this region. We conclude that MH2 contains a unique assembly of 3'-terminal sequences,...

results in this study, seven sirna molecules were rationally designed against the nucleoprotein gene and validated using various computational methods for silencing different strains of rsv. additionally, three effective sirna molecules targeting the overlapping region of m2/l mrna were designed. conclusions this approach provides insight and a validated strategy for chemical synthesis of an an...

The stability of potential RNA stem-loop structures in human immunodeficiency virus isolates, HTLV-III and ARV, has been calculated, and the relevance to the local significant secondary structures in the sequence has been tested statistically using a Monte Carlo simulation method. Potentially significant structures exist in the 5'non-coding region, the boundary regions between the protein codin...
