Defective expression of mouse adenovirus Fl in human cells

Abstract

HeLa cells infected with mouse adenovirus strain Fl ( AdFl ) produce at least 2000 times less virus than permissive mouse 3T3 cells. Viral DNA synthesis, however, proceeds unimpaired. The defect in virion production was linked to a dramatic reduction in the synthesis of AdFl structural proteins, in particular the hexon. The identity of the AdFl hexon gene product was recognized through its immunogenic reactivity towards an antiserum raised against the human adenovirus type 2 (Ad2) hexon gene product. This cross-reactivity is reflected in an extensive DNA sequence homology between AdFl and Ad2 DNA at position 53-60, the locus of the hexon gene, on the Ad2 physical map. Through hybridization at different formamide concentrations, the present study identifies one additional, highly conserved region at map positions 14-15 on the Ad2 genome.
