title: Repressed expression of the HER-2/c-erbB-2 proto-oncogene by the adenovirus E1a gene products.
abstract: The E3 region of adenovirus induces down-regulation of epidermal growth factor receptor (EGFR) through endocytosis. Here we report that an EGFR-related protein, the HER-2/c-erbB-2 gene product, p185, is also down-regulated by adenovirus, but via a different mechanism. We found that the adenovirus E1a gene is responsible for the repression of HER-2/c-erbB-2 at the RNA level.
