Purpose : Alterations of the p16INK4A and P15INK4B gene
which are separated by 25 kb on chromo-some 9p21 have been reported in various
tumor derived cell lines and primary tumors, but the role of these genes in cervical
cancer is unknown.
Material and Method : To determine the frequency of deletions and point mutations of
these genes in human cervical cancer, we examined 57 primary tumors and matched
normal tissues, and 3 cervical cancer derived cell lines. All the tumor tissues and cell
lines were human papillomavirus (HPV)-positive. Deletions or point mutations of exon 2
of the p15INK4B gene and exons 1, 2, and 3 of the
P16INK4A gene were examined by polymerase chain reaction (PCR) and
direct sequencing , respectively .
Result : Our data indicate no evidence for intragenic homozygous deletion or point
mutation in the cervical cancer or cervical cancer derived cell lines. Conclusion:
Deletions or point mutations in the p15INK4B and
p16INK4Agene may not be required for the development of HPV-positive
cervical cancer or for establishment of cervical cancer cell lines.
