Translation Elongation Rate Measurement of Epstein-Barr Virus Strain GD1.

ABSTRACT: BACKGROUND:Epstein-Barr Virus (EBV) has a great co relationship with human malignancies such as gastric carcinoma. Synonymous codon investigations in viruses could help designing vaccine, to generate immunity. Codon Adaptation Index (CAI) has measured translation elongation rate, among the highly expressed genes. The aim of this study was: usage of "CAI" to measure translation efficiency to know how fast EBV-GD1 could produce its proteins. METHODS:The complete genomic sequences of human herpes virus 4 strain GD1 have retrieved from (GenBank accession no. AY961628) to extract all protein-coding genes. The sequences have analyzed with DAMBE software. RESULTS:The results have shown that CAI values for the EBV-GD1 genes were 0.76356 ± 0.02957. The highest and lowest CAI values were 0.82233 and 0.68321 respectively. The results have shown that highly expressed genes mostly had more codon usage bias than low expressed genes. CONCLUSION:The results provide and introduce not only a system, but also the principles in order to understand the pathogenesis and evolution of EBV-GD1, to open a window, in order to make a better product or vaccine to challenge with the virus.

Project description:The main target cells for Epstein-Barr virus (EBV) infection and persistence are B lymphocytes, although T and NK cells can also become infected. In this paper, we characterize the EBV present in 21 pediatric and adult patients who were treated in France for a range of diseases that involve infection of T or NK cells. Of these 21 cases, 5 pediatric patients (21%) and 11 adult patients (52%) were of Caucasian origin. In about 30% of the cases, some of the EBV genomes contain a large deletion. The deletions are different in every patient but tend to cluster near the BART region of the viral genome. Detailed investigation of a family in which several members have persistent T or NK cell infection by EBV indicates that the virus genome deletions arise or are selected independently in each individual patient. Genome sequence polymorphisms in the EBV in these T or NK cell diseases reflect the geographic origin of the patient and not a distinct type of EBV (the 21 cases studied included examples of both type 1 and type 2 EBV infection). Using virus produced from type 1 or type 2 EBV genomes cloned in bacterial artificial chromosome (BAC) vectors, we demonstrate infection of T cells in cord blood from healthy donors. Our results are consistent with transient infection of some T cells being part of normal asymptomatic infection by EBV in young children. IMPORTANCE EBV contributes to several types of human cancer. Some cancers and nonmalignant lymphoproliferative diseases involving T or NK cells contain EBV. These diseases are relatively frequent in Japan and China and have been shown sometimes to have deletions in the EBV genome in the disease cells. We identify further examples of deletions within the EBV genome associated with T or NK cell diseases, and we provide evidence that the virus genomes with these deletions are most likely selected in the individual cases, rather than being transmitted between people during infection. We demonstrate EBV infection of cord blood T cells by highly characterized, cloned EBV genomes and suggest that transient infection of T cells may be part of normal asymptomatic infection by EBV in young children.
