Cervical cancer is, on a global scale, the second most common form of
cancer in women. Development of cervical carcinoma is strongly associated
with infection by certain types of human papillomavirus (HPV). To
facilitate the detection and molecular typing of HPV in clinical samples,
nested-PCR amplification systems were developed for regions of the E1 and
L1 genes. The nested amplifications were performed in a single reaction
tube, and shifting between inner and outer primer pairs was achieved by a
two-phase amplification with different annealing temperatures. This method
eliminates cross- contamination between samples during transfer from the
first to the second amplification step. A set of type-specific
oligonucleotide probes were designed for the E1 system and used to
distinguish 19 genital HPV types. The sensitivities of our amplification
systems compare favorably with that for the L1 system on the basis of the
MY09- MY11 primer pair (M.M. Manos, Y. Ting, D. K. Wright, A. J. Lewis, T.
R. Broker, and S. M. Wolinsky, Cancer Cells 7:209-214, 1989) and our
systems can be used on materials such as HPV-infected cell lines, cytobrush
samples, cancer biopsies, and recent as well as archival Papanicolaou (Pap)
smears. The high sensitivity coupled with the effective elimination of
contamination in the transfer between the two amplification steps of the
nested PCR makes these systems suitable for research as well as clinical
analyses.
