Infection with human papillomaviruses (HPV), and suppression of apoptosis and cell adhesion are putative aetiological factors to cervical carcinogenesis. However, controversial results have been reported with respect to their relationships with cervical carcinomas. Here we analysed papillomavirus infection, apoptotic index (AI), expressions of the anti-apoptotic proteins Bcl-2 and Survivin, and expression of the cell-adhesion protein CD44 in cervical tissue samples from individuals with and without cervical carcinomas. Although both HPV16 and HPV18 are reportedly important aetiological factors, we found that cervical carcinomas were highly associated with HPV16 but not HPV18 infection. Immunohistochemistry showed that the percentages of cells expressing Bcl-2, Survivin, and CD44v6 were greatly increased in samples of cervical carcinomas. Furthermore, the expression rates of Survivin and CD44v6 increased whereas that of Bcl-2 declined as cervical cancers developed into more advanced clinical or histopathological stages. Surprisingly, there was little difference in AI between control and cervical cancer samples. These observations provide further evidence that HPV infection, apoptosis and cell adhesion abnormalities are related to cervical cancers. They also suggest that Bcl-2, Survivin and CD44v6 expressions, and HPV16 infection could be useful indices in screening of cervical carcinomas.
