Detection of the human papillomavirus 58 physical state using the amplification of papillomavirus oncogene transcripts assay
HPV 58 is detected commonly in cervical cancer in East Asian countries. To evaluate the HPV 58 physical state, the amplification of papillomavirus oncogene transcripts (APOT) and hybridisation assays were established. Episome- and integrate-derived transcripts were confirmed by direct sequencing. Tw...

HPV 58 is detected commonly in cervical cancer in East Asian countries. To evaluate the HPV 58 physical state, the amplification of papillomavirus oncogene transcripts (APOT) and hybridisation assays were established. Episome- and integrate-derived transcripts were confirmed by direct sequencing. Twenty-nine HPV 58 positive samples from various cervical lesions were used. The results showed that the episome-derived transcripts were recognised as two major specific amplified products (1040 and 714. bp).
