Germ-line mutations in the p53 gene predispose individuals to Li-Fraumeni syndrome (LFS). The cell cycle checkpoint kinases CHK1 and CHK2 act upstream of p53 in DNA damage responses, and recently rare germ-line mutations in CHK2 were reported in LFS families. We have analyzed CHK1, CHK2, and p53 genes for mutations in 44 Finnish families with LFS,(More)
Internationally comparable quality assurance of Human Papillomavirus (HPV) DNA detection and typing methods is essential for evaluation of HPV vaccines and effective monitoring and implementation of HPV vaccination programs. Therefore, the World Health Organization (WHO) HPV Laboratory Network (LabNet) designed an international proficiency study. Following(More)
A panel of 24 monoclonal antibodies (MAbs) was generated against human papillomavirus (HPV) types 16 and 18 L1 virus-like particles (VLPs). The MAbs were screened for reactivity to a variety of VLPs prepared from HPV-6, -11, -16, -18, -31, -33, -35, and -45, cottontail rabbit papillomavirus, bovine papillomavirus type 1, and a set of 35 overlapping(More)
Human papillomavirus (HPV) types 16 and 18 are the major risk factors for cervical carcinoma, whereas HPV types 6 and 11 cause benign genital lesions. We wanted to study the joint effect of simultaneous infections with the oncogenic and non-oncogenic HPV types on risk of subsequent development of cervical carcinoma. A cohort of 530,000 women who had donated(More)
The epidemiology of cervical cancer indicates the presence of a sexually transmitted risk factor, attributable at least in part to infection with human papillomavirus (HPV) type 16 or 18. We performed a seroepidemiological study of HPV and cervical cancer in the counties of Västerbotten and Norrbotten in Northern Sweden, a low-risk area for cervical cancer.(More)
Streptococcus pneumoniae serotypes 6B and 6A are important causes of infections, yet only 6B is included in current vaccines. It is, therefore, crucial to evaluate whether functional antibodies are produced against both types after vaccination. Concentration and opsonophagocytic activity (OPA) of antibodies to 6B and 6A polysaccharides were determined in(More)
OBJECTIVE The objective of the study was to evaluate whether typing of human papillomavirus (HPV) among women with low-grade cervical cytology can improve the ability to identify women with cervical cancer or cervical intraepithelial neoplasia grade III (CIN III or worse). STUDY DESIGN A total of 1595 women with low-grade cervical cytology participating(More)
Established Human Papillomavirus (HPV) types, up to HPV202, belong to 49 species in five genera. International standardization in classification and quality standards for HPV type designation and detection is ensured by the International HPV Reference Center. The center i) receives clones of potentially novel HPV types, re-clones and re-sequences them. If(More)
BACKGROUND Anal epidermoid carcinoma is a relatively rare tumor, but its incidence has been increasing rapidly during the past few years. Genetic material from the major oncogenic types of human papillomavirus (HPV), types 16 and 18, has regularly been demonstrated in a substantial proportion of anal cancers, suggesting an etiologic role of HPV infection.(More)
In a seroepidemiological study of incident cervical cancer, 94 cases and 188 population-based controls were used to evaluate the disease-association of IgG and IgA antibody responses against 6 human papillomavirus (HPV) type-16 antigens. Nine of the tested antibody responses were positively associated with cervical cancer, with odds ratios (ORs) ranging(More)
