Nonstructural protein-1 of respiratory syncytial virus regulates HOX gene expression through interacting with histone.

Human respiratory syncytial virus (RSV), a major cause of severe respiratory diseases, constitutes an important risk factor for the development of subsequent asthma. In searching for its mechanism, the present study was designed to screen the interacting proteins of two important nonstructural (NS) proteins in human BECs. The subcellular localization and the effects of NS on HOX gene expression were also examined.
