Abstract:	Virus infection usually alters the host cell and shuts off the synthesis of cellular macromolecules. In order to screen the upregulated cellular transcripts during pseudorabies virus (PRV) infection, we employed the mRNA differential display technique. The screen is based on positive selection at the mRNA level for genes expressed in normal cells but increased in corresponding PRV-infected cells. Over 14000 species of mRNA, isolated from mock-infected and PRV-infected Madin-Darby bovine kidney cell at l h post infection, were screened, and 40 candidate clones were recovered. Southern blot analysis revealed that 17 out of 40 candidate clones, were enhanced in PRV-infected cells. Partial DNA sequences demonstrated that 17 clones were distinct cellular genes, including those encoding the modulators of signal transduction (saposin, 14-3-3, adenylate kinase, adenylyl cyclase, protein kinase C-α), those encoding the components of translation (fau, ribosomal proteins S11, L31, L36), other cellular genes (peptidase, cyclin E, rchl, oligo-C-rich single-stranded nucleic acid binding protein, rap, arginyl-tRNA synthetase), and two unknown genes. Thus, this study identifies successfully the transcriptionally regulated cellular genes which are associated with PRV infection. Furthermore, this study provides support for the use of mRNA differential display as a method to rapidly isolate differentially expressed genes in virus infection.
