We speculate that the human papillomavirus late mRNAs , produced from several hundred copies of the virus genome present in infected cells , compete with the c - fos mRNAs for destabilizing cellular factors and that this may lead to elevated Fos protein levels in human papillomavirus infected cells .
 GENE: c - fos mRNAs; GENE: Fos protein
