Replicating, tumor selective viruses are being tested as potential treatments for human cancers. Hypoxia is a pathophysiological cancer condition that alters the lytic potential of the replication-competent adenovirus serotype 5 (Ad5) virus by a mechanism independent of receptor l evels or internalization rates. We extend these initial studies to examine the potential effects of hypoxia on the group B adenoviruses (Ads), adenovirus type 3 (Ad3) (group B1) and adenovirus type 11p (Ad11p) ( group B2). Receptor expression (CD46) is not altered by hypoxia. However, the lytic potential is compromised in a cell-dependent fashion. Consequently, our study suggests that group B replicating Ad-based treatments, like the group C Ad-5-based viruses, will need to be modified in order to effectively treat hypoxic components of human tumors.
