Expression of the human papillomavirus (HPV) gene was examined in HPV-positive laryngeal tumors. Moreover, the activity of the HPV long control region (LCR) was tested in cultured laryngeal epithelial cells. HPV-11 early genes were heterogeneously expressed in adult laryngeal papillomas. We found one laryngeal carcinoma case in whom the HPV-16 transforming genes, E6 and E7, were expressed. Both HPV-11 and -16 LCRs were active in cultured laryngeal epithelial cells from vocal cords. These results suggest that laryngeal epithelial and tumor cells are target cells for HPV gene expression.
