Abstract
Here we analyzed the gene expression profile of cells that stably express the severe acute respiratory
syndrome coronavirus (SARS-CoV) 3a protein to determine its effects on host functions. A lung epithelial
cell-line, A549, was chosen for this study because the lung is the primary organ infected by SARS-CoV and
fatalities resulted mainly from pulmonary complications. Our results showed that the expression of 3a
up-regulates the mRNA levels of all three subunits, A , B , and , of fibrinogen. Consequently, the intracellular
levels as well as the secretion of fibrinogen were increased. We also observed increased fibrinogen levels
in SARS-CoV-infected Vero E6 cells.
