چکیده

1. We produced mammalian expression vectors encoding the SARS coronavirus (SARS-CoV) accessory proteins with or without the fluorescence protein tag and cell lines with stable expression of these proteins. 2. The cellular localisation and function of the SARS-CoV accessory proteins was determined. 3. SARS 6 and SARS 8b proteins are localised to the endoplasmic reticulum and nucleus/cytoplasm, respectively, and both proteins stimulate host cell DNA synthesis.

Heterologous expression of SARS-CoV ORF10 and X5 genes in E. coli and Streptomyces lividans TK24.

In previous studies a variety of novel accessory genes has been identified that were interspersed among the structural genes of the SARS-CoV (severe acute respiratory syndrome coronavirus) genome. The predicted unknown proteins (PUPs) encoded by the accessory genes, which are considered to be unique to the SARS-CoV genome, might play important roles in the SARS-CoV infection. Two of these genes...

Investigating the Mechanism of Action of SARS-CoV-2 Virus for Drug Designing: A Review

Coronavirus Disease 2019 (COVID-19) is a viral pneumonia emerged in December 2019 in Wuhan, China. Its cause is a new virus from the coronavirus family scientifically named Coronavirus Acute Respiratory Syndrome 2 (SARS-CoV-2). In this review study, articles published in English until March 23, 2020 on new coronavirus infection were reviewed. These articles are obtained by searching in PubMed, ...

Molecular and genetic characterisation of the SARS coronavirus auxiliary protein X1 in Drosophila (Supplement 4)

1. We have generated monoclonal antibodies against the SARS coronavirus (SARS-CoV) X1/3a protein (3a), which are suitable for western blotting, immunocytochemistry, and immunohistochemistry. 2. We have established and characterised an in-vivo 3a transgenic Drosophila model, and demonstrated its usefulness in studying SARS-CoV 3a gene function. 3. We validated our in-vivo findings on 3a gene fun...

Contributions of the structural proteins of severe acute respiratory syndrome coronavirus to protective immunity.

We investigated the contributions of the structural proteins of severe acute respiratory syndrome (SARS) coronavirus (CoV) to protective immunity by expressing them individually and in combinations from a recombinant parainfluenza virus (PIV) type 3 vector called BHPIV3. This vector provided direct immunization of the respiratory tract, the major site of SARS transmission, replication, and dise...
