[Cloning and sequencing of human papillomavirus 16 L1 gene from cervical carcinoma tissues of Chinese women].

OBJECTIVE

Human papillomavirus type 16 (HPV16) is highly related with the development of cervical carcinoma. HPV16 late gene L1 encodes its main capsid protein. This study is to analyze the whole sequence of L1 gene of HPV16 of the Chinese isolates.

METHODS

Three samples of HPV16 L1 gene were amplified from cervical carcinoma tissues of Chinese patients by PCR and then cloned and sequenced.

RESULTS

There were four sites in nucleic acid sequences of all three HPV16 L1 fragments were different from the originally reported sequence of HPV16 and the differed sequences had changed the triplet codes, therefore, subsequently changed the amino acids it coded.

CONCLUSION

The results showed that some mutation had taken place in the nucleotide sequence of L1 gene of HPV16 obtained from the cervical carcinoma tissues of Chinese women.
